Effect of intravenous amiodarone in patients with intraventricular conduction disorders

Using His bundle recordings and stimulation techniques, theelectrical effects of amiodarone (5 mg/kg intravenously) wereassessed in 12 patients aged 34–80 years (mean 65) exhibitingin sinus rhythm, intraventricular conduction disturbances. Bundlebranch block was present in 10 patients: left bundle branchblock in three patients, right bundle branch block in three,bilateral bundle branch block in four. All the patients hada long H-V interval (65–80 ms; mean 71). As has been previouslyreported, amiodarone slowed the sinus rate, prolonged the QTinterval, increased the atrial effective refractory period anddepressed A-V nodal conduction. Despite the presence of advancedconduction disturbances within the His-Purkinje system, amiodaronedid not alter the H-V interval in 11 patients and increasedit in one by only 5 ms. Thus, clinically, the use of amiodaronein patients with bundle branch block should be safe.     

The use of intravenous buprenorphine for the treatment of opioid withdrawal in medically ill hospitalized patients

The aim of this study was to assess the safety of buprenorphine administered intravenously for the treatment of opioid withdrawal in medically ill hospitalized patients. Data regarding demographic information, number of doses of buprenorphine, and measures of buprenorphine's effects were collected via chart reviews for 30 heroin-dependent patients who received buprenorphine intravenously during their hospitalization for an acute medical problem. No respiratory depression was observed, and no patients reported feeling "high." All patients reported that buprenorphine decreased withdrawal symptoms. Thus, intravenous administration of buprenorphine appears to be safe for the treatment of opioid withdrawal.     

Hemodynamic effects of intravenous amiodarone

Amiodarone is a potent antiarrhythmic agent that is effective in controlling both atrial and ventricular arrhythmias. Recently, intravenous administration was demonstrated to be effective in the acute management of rhythm disorders and, in addition, appeared to shorten the loading period normally required for oral drug administration. This investigation examined the hemodynamic effects of amiodarone after both acute intravenous bolus and continuous intravenous administration. Patients with a left ventricular ejection fraction greater than 0.35 experienced improved cardiac performance due to both acute and chronic peripheral vasodilation. However, patients with a lower ejection fraction developed a 20% decrease in cardiac index and clinically significant elevation of right heart pressures after acute bolus administration; these changes were variably compensated for by peripheral vasodilation when the drug was administered intravenously over 3 to 5 days continuously. Therefore, intravenous amiodarone can result in significant impairment of left ventricular performance in patients with preexisting left ventricular dysfunction.     

静脉用胺碘酮和毛花甙C转复阵发性房颤即时疗效对比

目的:比较静脉用胺碘酮和毛花甙C治疗阵发性房颤(PAF)的即时疗效和安全性。方法:84例发作时间在 24～72 h的PAF患者被随机分为胺碘酮组和毛花甙C组(每组42例),分别静脉内给予胺碘酮150～1180 mg和毛花甙C 0．4～0．8 mg。结果:胺碘酮和毛花甙C PAF转复率分别是83．3％和42．9％(P<0．01);未转复者的心室率在胺碘酮组由(128．4±12．3)降至(87．8±11．4)次／min(P<0．01),毛花甙C组由(129．6±13．1)降至(90．3± 11．9)次／min(P<0．01)。两组均无严重副作用发生。结论:静脉用胺碘酮治疗阵发性房颤有效且安全,其转复率显著高于毛花甙C。     

Use of intravenous amiodarone for emergency treatment of life-threatening ventricular arrhythmias

Efficacy, side effects and predictors of response for intravenous amiodarone were evaluated in 46 patients with recurrent drug-refractory sustained ventricular tachycardia or ventricular fibrillation, or both, who were treated with intravenous amiodarone. Of the 46 patients, 27 (58.5%) responded early to intravenous amiodarone and 6 (13%) showed a late response to amiodarone. The majority of patients who responded to intravenous amiodarone did so within the first 2 h of therapy, and all responded within 84 h. Patients with an ejection fraction greater than 25% were more likely to respond (p less than 0.05). Major side effects occurred in 13% of patients. The cumulative 2 year mortality rate due to arrhythmia recurrence or sudden death for responders discharged from the hospital was 23% and the cumulative overall 2 year mortality rate was 46%. In conclusion, intravenous amiodarone is rapidly effective in the majority of patients with recurrent ventricular tachycardia or ventricular fibrillation refractory to other drugs. The poor long-term outcome of patients who require this therapy, respond to it and are discharged on long-term oral amiodarone therapy warrants consideration of other long-term treatment of these patients. Use of intravenous amiodarone is an important new modality in the treatment of drug-refractory malignant ventricular arrhythmias.
