Preface to the Sixth Edition The year 2005 marks the 10-year anniversary of the publication of the Medicine Blue Book. I wrote the draft during my intemship and completed the book my first year of residency at Manila Doctors Hospital. Even then, my utmost desire in sharing this book is to assist the many struggling doctors and nursesin our different training institutions. I had seen how hard and how unrewarding. medical training can be. I hope the Blue Book can be your friend and companion at some point in your career. One of the biggest problems afflicting our country right now is the high cost of healthcare. To address this, the Blue Book contains several unique features: 1) effective drug options are listed whenever possible and noted with a smile =) icon, (2) priority laboratory exams to request are highlighted in bold, (3) the treatment regimens are generally listed according to importance, which means that crucial treatment strategies are listed first and supportive treatments are listed last, (4) the dosages of drugs have been adjusted for the average Asian patient, and (5) only tests and drugs available in our local setting are included. This edition presents major revisions and updates in all chapters. The latest (local ones if available) have been utilized. Again, myprofuse thanks to, Clemente Amante, Dr. Virgilio Banez, Dr. Carlos Chua, Dr. Kenneth Hartigan-Go, Dr. Ruby Go, Dr. Cecilia Montalban, Dr. Elizabeth Montemayor and Camilo Roa Jr. for their selfless and untiring efforts in updating the text. I am also greatly indebted to several people in my medical education: Dr. P. Ariniego, Medical Director at De La Salle University Medical Center; , Dr. Nelson S. Abelardo, past Chair of the Department of Internal Medicine at TheManila Doctors Hospital; and Dr. Rody G. Sy, former Head of the Section of Cardiology at UP-Philippine General Hospital. Finally, I would like to thank my parents, Mr. Ong Yong and Mrs. Juanita Tan Ong, for their wholehearted support in this endeavour. And to my wife, Anna for all her hard work in publishing this book. Above all, I humbly thank the Lord God for His guidance and inspiration. I can accomplish nothing without Him but "I can do everything in Christ who strengthens me." Thank you for reading and may God bless us always. Willie T. Ong

I am Dr. Neo. Aside from being trained with the knowledge and skills of western medicine, I also have proclivities in unconventional software applications which lead me to this work, the 6 th Edition of the Medicine Blue Book. The medicine Blue book has been integral in our line of work. From med school, internship, moonlighting, cross consultation beyond our specialties to treating our neighbours knocking at our doors late at night with tummy cramps. We doctors live underpaid and overworked conditions. With the MD to nursing phenomena, the medical diasporas, the mistrust of patients, threat from the government and media of malpractice bills who know nothing of our line of work and passions. We are one of the unsung heroes of our nation. As part of this brotherhood in white, with blood and tears trailing our footsteps, this work is my tribute. To my mentors, seniors, subordinates, your ultimate sacrifices did not go unnoticed. To the original authors of the book, I deeply apologize for lifting your whole work to be shared to the medical force in their PDA, which is handier nowadays than bringing different books and references. I hope you could consider it as my ultimate complement and a gesturing of honouring you for choosing your work to be selflessly shared to our other brothers and sisters-in-arms braving their training and practice without gain except for the satisfaction that we have helped them. I hope you could also forgive my humility which would seem to be cowardice represented by my anonymity. Mabuhay tayong lahat.

ADVANCED CARDIAC LIFE SUPPORT To Cardiology Page To Main Table of Contents To Detailed Table of Contents Basic Principle: To sustain life, (1) blood must circulate and (2) blood must be oxygenated optimally. General Guidelines: Take command. Obtain brief history. Identify and treat reversible cause: 5H’s: Hypovolemia, Hypoxia, Hydrogen ion (acidosis), Hyperkalemia or hypokalemia (other metabolic problems), Hypothermia. 5T’s: Tablets (drug overdose, accidents), Tamponade cardiac, Tension pneumothorax, Thrombosis coronary (MI, Thrombosis pulmonary (embolism). Step 1: Circulation. Auscultate the precordial area for a heartbeat while palpating for the carotid pulse. If negative, start CPR. Note: Place bedboard. Do effective 4-5 cms sternal compressions. Step 2: Oxygenate Optimally. Is the patient cyanotic? Is the patient still breathing? If negative, check airway and do ambu bagging with 'tight' face mask. Note: Give 100% oxygen. Make sure ambu bag tube is connected to the oxygen tank. Suction secretions as needed. Hyperventilate initially. Step 3: Treat the Cardiac Rhythm. Assess by cardiac monitor. Done simultaneously: l. Insert IV line. 2. Intubate patient if necessary (for asystole, electromechanical dissociation, bradyarrhythmia, or persistently unstable rhythms). 3. Get ABG's if with pulse (treat hypoxemia and acidosis). I. Rhythm: Asystole (Silent Heart) 1. Continue CPR. Obtain IV access. 2. Epinephrine (1 mg/ampnle) 1-2 ampules IV stat q 3-5 minntes continuously until there is a cardiac rhythm or until CPR is stopped. May give epinephrine 1 mg ampule in 10 ml NSS via ET tube q 3-5 minutes if no IV line is inserted yet. 3. If unable to rule out fine ventricular fibrillation, defibrillate with 360 Joules. 4. Atropine 1 mg IV; repeat q 3-5 min. Maximum of 3 mg. 5. Consider external or transvenous pacing. 6. Consider Bicarbonate 1 amp (1 meq/kg) if more than 15 minutes have elapsed since the heart has stopped. II. Rhythm: Ventricular Fibrillation or Pulse less Ventricular Tachycardia l. Defibrillate with UNsynchronized 200 Joules stat, repeat with 300 Joules if unsuccessful, then 360 Joules. 2. Continue CPR between defibrillations or until a defibrillator is available. 3. If no conversion, give epineprhine 1 ampule prior to next defibrillation for cases of resistant or fine ventricular fibrillation. Repeat q 3-5 minutes as needed. 4. Continue Defibrillation until rhythm is converted to sinus. 5. Consider anti-arrhythmic drugs: a. Amiodarone 150-300 mg (1-2 ampules) slow IV in 10 minutes for resistant ventricular fibrillation or ventricular tachycardia. Repeat dose if necessary. or b. Lidocaine 50-100 mg (1 mg/kg) IV and then start drip at 2 mg/min. May repeat bolus 40 mg (0.5 mg/kg) IV ofter 5 minutes. Maximum of 200 mg (3 mg/kg). If necessary, increase drip rate by 1 mg/min to maximum of 4 mg/min. May give Lidocaine via ET tube plus 10 ml NSS.
6. For polymorphic ventricular tachycardia (torsade de pointes), give Magnesium Sulfate 1-2 gm IV diluted in 100 ml DSW and given in 2 minutes. 7. Consider Sodium Bicarbonate 1 amp slow IV. III. Rhythm: Unstable Ventricular Tachycardia with Pulse For presence of chest pain, dyspnea, MI, heart failure, or systolic BP < 90 mmHg: 1. Cardiovert with synchronized 100, 200, 300 Joules. If patient is awake give Midazolam 2-5 mg IV for sedation. May omit precordial thump. 2. Consider anti-arrhythmic: a. Amiodarone 150-300 mg (1-2 ampules) slow IV in 10 minutes. Repeat dose i f necessary. or b. Lidocaine 50-100 mg (1 mg/kg) IV and then start drip at 2 mg/min. May repeat bolus 40 mg (0.5 mg/kg) IV after 5 minutes. Maximum of 200 mg. 3. If no conversion, cardiovert at synchronized 360 J, or if recurrent ventricular tachycardia, cardiovert again starting at previously successful energy level, then after conversion, continue medications. IV. Rhythm: Stable Ventricular Tachycardia with Pulse 1. Precordial thump. 2. Give anti-arrhythmic drugs: a. Amiodarone 150 mg slow IV (1 ampule) in 10 minutes. or b. Lidocaine 50-100 mg (1 mg/kg) IV and then start drip at 2 mg/min. May repeat bolus 40 mg (0.5 mg/kg) 1V every 5 minutes until VT resolves. Maximum of 200 mg. 3. If drugs fail, cardiovert with synchronized 100, 200 Joules. 4. Treat accordingly if cardiac rhythm degenerates. V. Rhythm: Bradycardia A. For chest pain, dyspnea, drowsiness, heart failure, or systolic BP < 90 mm Hg: 1. Atropine 0.5-1 mg IV stat. Maximum of 3 mg (0.04 mg/kg). May give via ET tube with 10 ml NSS. 2. Continue CPR support if HR < 40 bpm. 3. Consider external or transvenous pacing. 4. Consider Dopamine drip or Epinephrine drip as a temporizing measure B. For type II second degree dh third degree AV block, consider external or transvenous pacing. C. If without symptoms, observe! VI. Rhythm: Electromechanical Dissociation (EMD) Definition: Sinus rhythm by cardiac monitor but without palpable pulses. No BP. Etiology: EMD can be secondary to inadequate fluid volume, pericardial tamponade, tension pneumothorax, hypoxemia or acidosis. Less correctible causes include massive MI, prolonged ischemia during resuscitation and pulmonary embolus. 1. Continue CPR 2. Correct primary problem (see etiology). 3.. Epineprhine 1 mg IV q 3-5 min 4. Consider Bicarbonate 1 amp (44 meq) slow IV. VI. Rhythm Successfully Converted to Sinus Rhythm: 1. If Systolic BP = 100 mm Hg: Obtain laboratory exams: ABG, ECG (check for MI), CXRCBC, Na, K, RBS, Creatinine 2 If Systolic BP =90 mm Hg: i. Start Inotropics: Dopamine with or without Dobutamine. ii. Correct low volume, acidosis and hypoxemia. iii. Do ABG and other laboratory exams if feasible. Advice
a. Adequate airway, ventilation, oxygenation, chest compression and defibrillation are more important than initiating IV line and injecting medications. b. IV medications should be given by bolus with few exceptions. After each IV medicine, give 20-30 ml bolus of IV fluid and elevate the extremity. c. Do most of your interventions in the first 10 minutes of the CPR. Otherwise, the chance of reviving the patient decreases markedly. d. Lastly, treat the patient, not the cardiac monitor.

CONGESTIVE HEART FAILURE (For Systolic Heart Failure) To Cardiology Page To Main Table of Contents To Detailed Table of Contents Data: Systolic vs. Diastolic Heart Failure: 1. Systolic Heart Failure: Markedly dilated left ventricle, low ejection fraction (problem with systolic LV contraction phase). Treatment approach indicated below. 2. Diastolic Heart Failure: Normal left ventricle size, usually concentrically hypertrophied, normal ejection fraction (problem with diastolic LV relaxation phase and stiff LV). Treatment is different from systolic heart failure. Give beta-blockers and calcium-channel blockers. Table 1-3.

Basic Exams: CBC, FBS, K, Creatinine, ECG, Chest X-ray PA-L B. Other Helpful Tests: Platelet count, PT, PTT, Urinalysis C. Optional Tests as Indicated: ABG, Total Bilirubin, Albumin, SGOT, 2-D Echo with doppler III. Treatment Approach: A. Correct anemia, poor nutritional status, hypovolemia, polycythemia, hypertension, electrolyte abnormality, cardiac arrhythmia, high blood sugar, pulmonary disease causing hypoxemia,
adrenal hyporesponse secondary to long-term steroid use. B. CP clearance and need for intraoperative monitoring. Three basic questions: 1. What is the medical status of the patient? a. What is the functional capacity of the patient? Can the patient climb at least two flights of stairs with ease? b. What is the patient's Goldman's Classification (Class I – IV)? Note: Low-risk patients to clear leave good functional capacity and are Goldman’s Class L 2. What is the operative procedure? a. High-risk surgery: Emergency major operation, aortic and other major peripheral vascular surgery, anticipated prolonged surgery with large blood loss. b. Intermediate risk surgery: Carotid endarterectomy, head and neck, intraperitoneal and intrathoracic, orthopedic, prostate surgery. c. Low-risk surgery: Breast, cataract, endoscopy, superficial procedures. 3. What type of anesthesia is to be used? From high-risk to low-risk: General anesthesia, spinal anesthesia, subarachnoid block, regional anesthesia, local anesthesia. C. Based on the answers above, we can now estimate the operative risk involved. Low-risk patients undergoing low-risk procedures have low operative risk. Conversely, high-risk patients undergoing high-risk procedures have high operative risk and need intraoperative monitoring. For other combinations of risk, the physician is advised to use his/her clinical judgment before clearing the patient. To Cardiology Page To Main Table of Contents To Detailed Table of Contents

INDICATIONS FOR PERMANENT PACEMAKER INSERTION To Cardiology Page To Main Table of Contents To Detailed Table of Contents Data There is general agreement that a permanent pacemaker should be implanted in the following conditions (Class I Indications): A. Complete Heart Block with l. (+) Symptoms due to the AV block (e.g. syncope, heart failure) 2. Asystole = 3 seconds by Holter monitoring even if without symptoms 3. HR < 40 bpm even without symptoms (any escape rhythm < 40 bpm) B. 2nd Degree AV block, permanent or intermittent, with symptomatic bradycardia C. Sinus node dysfunction with symptomatic bradycardia. In some patients this due to long-term essential drug therapy for which there are no acceptable alternatives e.g. digoxin for tachycardia-bradycardia syndrome. D. Carotid sinus stimulation causing recurrent syncope or asystole > 3 seconds in the absence of any medication that depresses the sinus node or AV conduction. Additional Data: 1. Patients should not be taking any drug that depresses the heart rate (i.e. digoxin, amiodarone, beta-blockers etc.). For example, digoxin needs 5 days to be completely excreted by the body, hence, we may opt to temporize the patient for 5 days even if he/she fulfills the above criteria. 2. The key clue in most of the above indications is the presence of symptoms. 3. Acute MI cases who develop bradyarryhthmias are usually treated with temporary internal pacing since the problem is reversible. Inferior wall MI is associated with edema of the AV node which usually resolves in 1- 2 weeks. 4. In poor patients who cannot afford permanent pacing, drug therapy with Bricanyl 2.5 mg tab BID-TID may be given with inconsistent results. In severe symptomatic cases, permanent pacing is the only alterative. The cheapest pacemaker available costs around Php 50,000.

WHO Category I* a. TB patients: new smear-positive PTB; new smear negative PTB with extensive parenchymal involvement; new cases of severe forms of extra-pulmonary TB. b. Alternative TB Treatment Regimen i. Initial phase: 2HRZE (four drugs) ii. Continuation phase: 4HR
2.
WHO Category II a. TB patients: Sputum smear-positive: relapse; treatment after interruption b. Alternative TB Treatment Regimen i. Initial phase: 2HRZES and 1HRZE (Five drugs) ii. Continuation phase: 5HRE
3.
WHO Category III** a. TB patients: New smear-negative PTB (other than in Category 1) new less severe forms of extra-pulmonary TB. b. Alternative TB Treatment Regimen i. Initial phase: 2HRZ (three drugs) ii. Continuation phase: 4HR
* Give this regimen if with high bacterial load, cavitary lesions, AFB+4 smears, or high community resistance (e.g. NCR, Cebu, Davao, Zamboanga, Cavite, Pampanga). If with cavitary disease, give Streptomycin IM alternate days (60 doses) instead of Ethambutol ** May give this cheaper regimen for newly diagnosed TB and those cases found in low community resistance Source: Maher D, Chavlet P, & Spinaci S, et el (1997).

ATS Class 4: Previous PTB disease (e.g. Chest X-ray with minimal infiltrates but no symptoms of active disease or previously treated PTB) Treatment Algorithm Has patient completed past treatment of PTB? NO: Check old CXR if:
o
o
6 months stable CXR § If age 60 Just observe) § Repeat CXR after 3 months § If infiltrates increase or decrease, treat PTB as Class III.. If infiltrates are stable, stop treatment No previous CXR § Give 2HRZ/4HR § Repeat CXR after 2 months § If infiltrates increase or decrease, treat PTB as Class III.. If infiltrates are stable, stop treatment
YES: Observe and then Check old CXR if: o X-ray normal with normal or less infiltrates § Treat as PTB 3, 2HRZE/4HR (or 2HRZ/4HR) o X-ray the same , no changes § No treatment
6. ATS Class 5: PTB Suspect Treatment Plan: Check previous Chest x-ray Reclassify patient into Class III or Class IV in 2-3 months using sputum bacteriology or serial x-ray changes. 7. Multi-drug Resistant TB: Infection with strain of Mycobacterium tuberculosis which shows in-vitro resistance to at least Isoniazid and Rifampicin Treatment Plans: Use at least 4-5 drugs as hng as, a. Use at least 4-5 drugs as long as these include 2 drugs not previously taken. Do not add a single drug to a failing regimen to avoid resistance to the new drug. Consider continuing with H & R (most bactericidal) despite resistance, for example, if patient took HREZ X 6 months, may then add Streptomycin (first line drug) and Ofloxacin (second line drug. May discontinue either E or Z. b. Continue treatment for 18 months more from the time the patient’s sputum becomes AFB and culture negative. Get cultures to check sensitivity of TB organism. c. Consider Surgery for unilateral cavitary lesions in whom MDR-TB is established by the laboratory. Legend: H or INH honiazid R or RIF = Rifampicin Z or PZA Pyrazinamide E or EMB = Ethambutol S or STM Streptomycin I. Notes on Anti-TB Drug Intake: (Additional Treatment Plan for Active PTB) l. Instill in the patient’s mind the need to complete 6 months treatment. a. Since it is very difficult for patients to comply with multiple drug for the duration of at least six months, incomplete treatment not only decrease cure rate but also enhance development of resistance. It is ideal that treatment of TB should be done under direct supervision. “DOTS”Directly Observed Therapy Short Course requires actual observation during drug intake. There are now several DOTS centers in Manila to help doctors implement DOTS treatment even for private patients. Refer patients to Manila Doctors Hospital, PGH, Makati Medical Center and UST. b. Give all medications 1 hour before meals. It is ideal not to break the dose of the drug. c. If drugs are to be staggered because of side effects, make sure each drug component is still single dose. e.g. Rifampicin - before breakfast, EMB - before lunch, PZA - before supper d. Use only fixed dose combination, since most of these contain only 450 mg Rifampicin, add 150 mg Rifampicin if patient weighs > 60 kg or 130 lbs.
2. If patient cannot complete treatment, better not to start treatment at all to avoid emergence of resistance (MDR-TB). 3. The allowance for non-compliance is two weeks maximum, otherwise the treatment regimen should be started all over again. 4. Follow-up patients monthly. During initiation of treatment make patients follow- up after a week to see if there are drug side effects. 5. If after 6 months, the patient is still symptomatic, continue treatment but do sputum AFB and culture and reassess if the patient has MDRTB or cured TB with bronchiectasis. 6. Post-treatmeat follow-up: If two years has elapsed and the patient is still asymptomatic, long-term cure is anticipated. Relapse occurs in 1-2 % of cases. J. Tuberculosis in Special situations: 1. Pregnancy: a. HRE X 9 months (Standard regimen for pregnant patients) b. Give 50 mg of Pyridoxine as vitamin supplements. c. Avoid PZA, especially in the first trimester, unless resistance to H and R is highly suspected. d. Avoid Streptomycin: May cause 8th cranial nerve fetal abnormality. e. Breastfeeding is allowed: Take drugs after breastfeeding; TB drugs do not have toxic effect on nursing newborns. 2. Uremia or end-stage renal disease a 2 HRZ / 6 HR (Safest regimen for renal disease) b. Give INH + RMF +/- Pyridoxine at the regular doses administered after dialysis. c. Ethambutol: Decrease dose to 8-10 mg/kg/day d. Pyrazinamide: Decrease dose to 12-20 mg/kg/day e. Avoid Streptomycin (nephrotoxic) 3. Liver Disease/ Drag-induced Hepatitis: a. Stop anti TB drugs if (1) (+) jaundice or (2) Liver function test (SGOT, SGPT) > 3X the normal values b. Slowly resume INH and Etlambutol during first week. Resume Rifampicin during the second week and then PZA 3 days after. 4. Diabetes Mellitus: Continue treatment for a minimum of 9 months 5. Elderly patients > 65 years: Give HR X 9 months 6. Extrapulmonary Tuberculosis: a. Same treatment regimen as pulmonary TB b. For Central Nervous System TB: i.Use H, R, Z because of good penetration to the CNS ii.EMB and STM penetrate inflamed meninges only. 7. PTB in Children (Primary Complex): a. mixed disease: INH 5mg/kg/day (max of 300mg) + RMP 10mg/kg/day (max of 600 mg) b. extensive disease: STM 10-18mg/kg/day (max of 750mg) or EMB 15-20 mg/kg/day – avoid in young children whose visual acuity cannot be monitored, PZA 20-30 mg/kg/day (no studies yet) To Pulmonology Page To Main Table of Contents To Detailed Table of Contents

HYPOKALEMIA To Nephrology Page To Main Table of Contents To Detailed Table of Contents Data: A. Etiology: Diarrhea, laxative abuse use diuretics vomiting, check for hypertension (hyperaldosteronism or glucocorticoid excess), renal tubular acidosis, polymyositis, hypokalemic peroidic paralysis. B. Principles of Management of Hypokalemia:, 1. The clinical context dictates the need for therapy of hypokalemia. Hypokelemia per se does not necessarily justify treatment with potassium supplements or potassium sparing diuretics. 2. Assess the etiology (redistribution versus deficit) of the hypokalemia. 3. Assess and correct acid-base balance and extracellular fluid volume abnormalities. 4. Assess the level of renal function 5. Assess and correct serum tonicity and serum magnesium, if needed. 6. Normokalemia or hypokamia in a context of metabolic acidosis or serum hypertonicity often indicates potassium deficits. 7. Potassium-sparing diuretics should not be used in patients at risk (patients with decreased renal function or patients receiving drugs impeding potassium homeostasis). 8. Only resistant hypokalmia justifies the use of two simultaneous treatment modalities of hypokalemia. 9. Assess the potential attribution of medications to hypokalemia and the underlying pathophysiology causative of hypokalemia and correct whenever possible. 10. Evaluate concurrent medications and/or existing clinical conditions that may aggravate the conscqueneps, of hypokalemia 11. Discontinue treatment of hypokaiemia whneever concentration is about 3.5-4.0 meq/l for fear of "overshoot" hyperkalemia or until a pattern of response is clearly established. 12. Whenever treating hypokalemia, follow the response to treatment by serial measurements of serum potassium concentration and if indicated, acid-base status. 13. The oral route of potassium replacement, using potassium chloride, is the safest and the preferred modality of treatment. The intravenous route of therapy should be reserved for extreme situations. C. Estimation of Potassium Deficit: 1. For a fall in serum potassium from 4.0 to 3,0 meq/l body potassium deficit is 200-3000 meq/70kg body weight 2. For serum potassium at 2.5 meq/L body deficit is 500 meq/70 kg body weight 3. For serum potassium at 2.0 meq/L body deficit is 700 meq/70 kg body weight Orders: Diagnostics: CBC, Serum K, repeat Serum K in 2-3 days Na, Ca, Mg, ABG Urine K, Urinalysis Therapeutics: 1. The oral route of administration is the safest and preferred mode of potassium replacement. Oral potassium should be given preferably as liquid with or after meals, or as tablet, which must be swallowed and not allowed to dissolve in the mouth; Dose depends on the clinical situation and the estimated deficit. e.g. Per Orem: Kalium durule 0.75gm (10 meq) TlD PO X 2-3 days or Oral KCl Solution 15-30 cc TID (1 gm KC1 = 14 meq K+) to be further diluted in oral feeding or water. Note: Each oral dose should not exceed 20-40 meq K+ 2. When potassium is provided by the intravenous route the use of peripheral vein is preferred over a
central route. The maximum rate at which potassium can be safely given into peripheral veins is usually 10-20 meq/hour. Higer rate maybe administeres if the clinical situation warrants more rapid correction of the hypokalemia. Usual concentration is 20-40 meq potassium in 1 liter of saline or dextrose solution. One must be aware of a decrement in serum potassium of about 0.2-1.4 meq/liter when potassium is administered glucose solute. e.g. Intravenous: Add 20-60 meq KCl in Plain NSS X 12 hours If potassium level is < 2 and (+) ECG abnormalities use glucose-free solution. When fluid restriction is necessary, up to 20 meq per 100 ml can be cautiously given over 1 hour via a microdrip. Higher concentrations of KCI may cause skin burns. 3. In the setting of severe hypokalemia, potassium can be delivered into the femoral vein with the tip of the catheter not in dose proximity to the heart The rate of administration should not exceed 60 meq/hour.

Serum potassium and the acuteness and rate of its rise 2. Clinics manifestatioas – ECG changes, cardiovascular, neuromuscular B. When possible, rapid determination of etiology 1. Inadequate renal excretion from renal failure with oliguria 2. Drugs that inhibit Renin-Angiotensin-Aldosterone system such as Beta-blockers, ACE-inhibitors, or NSAIDs C. Immediate discontinuation of all sources of potassium intake and agents that affect potassium homeostasis. D. Reversal of membreane abnormalities: Emergency treatment 1. Calcium gluconate 2. Hypertonic NaCl to yponatremic patients 3% NaCl or 50 ml sodium bicarbonate to 1 liter of NSS E. Redistribution of potassium from the extracellular space to the intrracellular space 1. Sodium bicarbonate IV 2. Insulin and glucose 3. Stimulation of Beta-2 adrenorcceptors (Salbutamol nebulization) F. External removal of potassium l. In stools: Cation exchange resin (Kayexelate or Sorbisterit) 2. In urine Increase urine flow rate and distal tubular delivery of sodium (loop diuretic: Furosemide IV bolus 70-80 mg) 3. By dialysis: Homodialysis or peritoneal dialysis Orders: Diagnostics: CBC Serum K, BUN, Creatinine, ECG-12 lead Therapeutics: A. Creatinine normal and not oliguric 1. Recheck serum potassium 2. Stop drugs which increase potassium (Beta-blockers ACE-inhibitors, NSAID) 3. Check other etiology of hyperkalemia B. Creatinlne increased and/or oliguria 1. Mild hyperkalemia (potassium level < 5.5 mmol/L): Restrict potassium intake; stop culprit drugs 2. Moderate hyperkalemia (potassium level = 5.5-6.5 mmo/L): a. Kayexelate or Sorbisterit 20 grams in 150 cc juice TID x 3 doses only (up to 4-5 doses/day) b. Diuretics: Furosemide 40-80 mg IV stat dose c. Optional: Beta -agonist (Salbutamol) nebulization 3. Severe hyperkalemia (potassium, level > 6.5 mmol.L) and/or (+) ECG changes: Mnemonic: G C S - Glucose, Calsium, gluconate & Sodium bicarbonate a. Calcium gluconate 10 ml 1 amp in 10% solution slow IV push in 5 minutes (at 2 ml/min) if with ECG changes. Repeat after 10 minutes if no improvement.. b. Glucose-Insulin: i. 50 ml of 50 % dextrose in water plus 10 units insulin in 2-5 minutes e.g. Mix D50-50 ml. + 10 units Humulin R slow IV stat then q 6 hours x 3 doges or ii. 500 ml of 10% dextrose 10 units insulin over 30-60 minutes (if volume overload is
not a problem) or iii. 1000 ml of 10% dextrose + 20 units insulin with one-third of the solution given in the first 30 minutes and the remainder over the subsequent 2-3 hours. Note: Method(a) can be repeated, if necessary, or can be followed by either (b) or (c). The latter 2 techniques lend themselves nicely to the additional maneuver of adding sodium bicarbonate (50-100 meq/L) to the dextrose solution. Potassium shift occurs in 30 minutes but benefits last for several hours. It is the best way to decrease potassium. c. Sodium Bicarbonate 1 amp slow IV push in 10 minutes Potassium shift occurs in < 15 minutes, with duration of 1-2 hours; this is the fastest way to decrease potassium. d. Beta-2 agonist :Albuterol (5 mg/ml) 20 mg by inhalation over 10 minutes. Onset of action is 15-30 minutes. 4. Prepare patient for dialysis if with renal failure or unresponsive to above measures.

2. Three Different Insulin Regimens: a. Insulin Alone (currently accepted) Shift completely to Insulin after failure of maximal oral hypoglycemics i. Single-dose: Less optimal control of postprandial blood glucose but convenient for the patient (once-a-day injection) ii. Split-dose:Better control than single-dose e.g. Humulin 15 units N SC at 6 a.m. (2/3 as morning dose) Humulin 5 units N SC at 6 p.m. (1/3 as evening dose) iii. Split-mix: Better control than single-dose or split-dose e.g. Humulin N 14 units, Humulin R 6 units at 6 a.m. Humulin N 7 units, Humulin R 3 units at 6 p.m. b. BIDS (Bedtime Insulin and Daytime Sulfonylureas) Combined Insulin & Oral hypoglycemic agents e.g. Diamicron 80 mg 1 tab TID PO 30 minutes before meals Humulin N 10-20 units SC at night c. Insulin + Oral Hypoglycemic Agents: Add Insulin treatment on top of Oral hypoglycemic agents Choose any of the 3 regimens in No.1 (usually Single-dose or Split-dose) eg. Humulin N 20 units SC at 6 a.m. single-dose + Diamicron 80 mg I tab TID 30 minutes premeals 3. Blood Sugar Monitoring of Patients: a. Out-patient: Two hours post-prandial, FBS, Hgb A1C b. In-patient: CBG (Capillary Blood Glucose) monitoring CBG OD = 6 a.m. premeals or 2 hours post-prandial (after) lunch CBG BID = 6 a.m. - 6 p.m. premeals CBG TID = 6 a.m. - 12 noon - 6 p.m. premeals CBG QID = 6 a.m. - 12 noon - 6 p.m. - 12 midnight premeals 4. How to Calculate the Daily Insulin Requirement of an In-patient. Step 1: Use Insulin Sliding Scale for 1 day only to observe daily insulin requirement of the patient. CBG < 160 = no insulin CBG 160 - 200 = 4 units Humulin R SC CBG 200-300 = 6-10 units Humulin R SC CBG 300-400 = 10-14 units Humulin R SC CBG > 400 = call Attending Physician Step 2: Get total daily Insulin requirement to achieve reasonable control. e.g. 30 units needed for the day Step 3: For patients on oral diet give 2/3 of total daily Insulin requirement in the morning and 1/3 in the evening e.g. Humulin N 20 units SC at 6 a.m. + Humulin N 10 units SC at 6 p.m. Step 4: For patients on oral NGT feedings round the clock, give 1/2 of total daily dose at 6 a.m. and 1/2 at 6 p.m. e.g. Humulin N 15 units SC at 6 a.m. + Humulin N 15 units SC at 6 p.m. Note: Give additional short-acting insulin as rescue doses for CBG > 200 mg % 5. For Type I Diabetes Mellitus: Refer these patients to an Endocrinologist for strict insulin treatment.

* In patients with severe thyrotoxicosis, points are assigned to the highest possible weighted description applicable in each category and scores totaled. When it is not possible to distinguish the effects of an intercurrent illness from those of the severe thyrotoxicosis per se, points are awarded such as to favor the diagnosis of storm and hence empiric therapy. A score of 45 or greater is highly suggestive of thyroid storm; a score of 25-44 is suggestive of impending storm, and a score below 25 is unlikely to re represent thyroid storm.

ALL ABOUT DRIPS To Main Table of Contents To Detailed Table of Contents
How to use the listed drip rates and equivalent dosages given: For example, the statement under number one for the daomine drip sees, “Drip of 2.5-10 mcg/kg/min is equivalent to 9-38 ugtts/min for a 50 kg patient.” This means that a dopamine drip of 2.5 mcg/kg/min is equivalent to giving 9 ugtts/min for a 50 kg patient while a dopamine drip of 10 mcg/kg/min is equivalent to 38 ugtts/min for a 50 kg patient. Using similar statements below as your guide, no tedious computations maybe necessary for the average patient. 1. Aminophylline Drip: D5W. 250 ml+ Aminophylline 250 mg/amp at 15-40 ugtts/min Maintenance Drip of 0.4-0.8 kg/kg/hr is equivalentto 20-40 ugtts/min for a 50 kg patient. Formula: ugtts/min= dose x BW LD = 5 mg/kg BW in 30 ml D5W in a soluset (if patient is not maintained on oral theophylline) Note: Maintenance infusion rate must be reduced to 0.2-0.3 mg/kg/hr for elderly patients, pregnant patients and those with CHF, liver disease or cor pulmonale 2. Amiodarone (Cordarone) Drip: Preparation: 150 mg/3 ml vial a IV Loading Dose: 5-10 mg/kgbody weightt/24 hour or 500-1000 mg in 24 hours Intravenous loading doses were given for an average of 4 days in clinical trials. Estimated maximum daily dose of 1000 rng/24 hours for Filipinos. Orders: Give 150 mg slow IV push over 10-30 minutes (with BP and HR monitoring) followed by D5W 250 ml+ 150 mg-300 mg IV Amiodarone to run for 24 hours. Supplemental doses of 150 mg IV over 10-30 mins may be given for recurrent arrhythmias especially during the early phases of dosing.
