These computerized devices “analyze” the rhythm and indicate if a shock is appropriate 50 mg imuran sale spasms in lower abdomen. Cardioversion Used for VT with a pulse buy cheap imuran 50 mg online muscle relaxant reversal drugs, atrial arrhythmias with rapid ventricular response (PAT, AF, or atrial flutter); an attempt to slow the heart or convert rhythm. Agents can include diazepam, midazolam with or without a narcotic such as morphine, or fentanyl. Keep the synchronizer switch on (prevents shocking during vulnerable part of QRS complex when shock may cause VF, so-called R-on-T phenomenon). Place paddles, apply pressure, and verify area is cleared as for the defibrillation steps. Most defibrillators default back to the unsynchronized mode to allow rapid shock in case of VF. External pacemakers can be set in the asynchronous (nondemand or fixed mode) or demand mode in the range of 30–180 bpm with current outputs from 0–200 mA. Adjust current upward until capture is achieved (ie, wide QRS after each pacer spike on ECG for bradycardia. OTHER COMMON EMERGENCIES The following material gives the treatment for other common emergencies. IV/IM/PO 1 mg/kg • Methylprednisolone DOSAGE: 1–2 mg/kg IV • Ranitidine (Zantac) DOSAGE: Adults. Give early consideration to Hydrocortisone sodium DOSAGE: 4 mg/kg IV q2–4h or Methylprednisolone DOSAGE: 2–4 mg/kg IV q4h Anticholinergic Crisis 21 Usually related to drug overdose. Patients present “red as a beet, mad as a hatter, hot as a furnace, dry as a bone, blind as a bat. Administer 1 amp (50 mL) of D50 IV manually; some recommend checking a stat glu- cose first 6. Dental Emergencies Not including facial fractures, there are generally two major categories of dental emergen- cies: toothaches with associated abscesses and avulsed (knocked-out) teeth. Most toothaches may be managed with antibiotics (usually penicillin-V 500 mg, q6h) and anal- gesics until proper dental attention can be obtained. These patients should be held for observation with special attention to maintaining the airway until a dental consult can be obtained. Infraorbital infections can lead to a cavernous sinus throm- bosis if allowed to progress. The best treat- ment is to reposition the displaced tooth back in the socket within 30 min or as soon as pos- sible. Hypercalcemia See Chapter 9, page 188 Hyperkalemia See Chapter 9, page 186 Hypertensive Crisis 1. Give orange juice with sugar if the patient is awake and alert; if not, give 1 amp of D50 IV (Peds. The following is a list of some common poisons with their antidotes (Dosages for adults, unless otherwise specified): Acetaminophen N-acetylcysteine, 140 mg/kg Anticholinesterases Atropine 0. Conscious Patient • Activated charcoal 1 g/kg, Contraindicated for iron, lithium, lead, alkali, acid. Seizures/Status Epilepticus Status epilepticus refers to >1 min of continuous seizure activity or back-to-back seizures without recovery in between. Be familiar with all the indications, contraindications, adverse effects, and drug interactions of any medication you prescribe. Medications are listed by class, and then the individual medications are listed in alpha- betical order by generic name. Some of the more common trade names are listed (in paren- theses after the generic name) for each medication. Because many medications are used to treat various conditions based on the medical literature and not listed in their package insert, we list common uses of the medication rather than the official “labeled indications” (FDA approved). If no pediatric dosage is provided, we assume the agent is not well established for this age group. Drug Enforcement Agency (Schedule I–V controlled substances) are indicated by the symbol [C]. The following is a general descrip- tion for the schedules of controlled substances: • Schedule I:All nonresearch use forbidden (eg, heroin, LSD, mescaline, etc) • Schedule II: High addictive potential; medical use accepted. Some states require special prescription form (eg, cocaine, morphine, methadone) • Schedule III: Low to moderate risk of physical dependence, high risk of psycholog- ical dependence; prescription must be rewritten after 6 months or five refills (eg, ac- etaminophen plus codeine) 22 475 Copyright 2002 The McGraw-Hill Companies, Inc. Discontinue immediately if hypersensitivity symptoms arise (fever, skin rash, fatigue, nausea, vomiting, diar- rhea or abdominal pain).
