Background: Droperidol and ondansetron have previously been found to prolong the QT interval in the treatment of postoperative nausea and vomiting. However, this adverse effect has never been confirmed and compared with both drugs under controlled conditions. The objective was to study the effects of droperidol and ondansetron alone or in combination on QT interval duration in healthy subjects.
Methods: Sixteen healthy volunteers, eight males and eight females, were enrolled in this prospective, double-blind, randomized, placebo-controlled study. Subjects received 1 mg droperidol, 4 mg ondansetron, 1 mg droperidol plus 4 mg ondansetron, or a placebo, intravenously in a crossover design. Fridericia-corrected QT interval (QTcF) and plasma concentrations were measured repeatedly during 10 h at each study period. The primary endpoint was the maximal placebo time-matched and baseline-subtracted QTcF prolongation (DeltaDeltaQTcF).
Results: Compared with placebo, both droperidol and ondansetron significantly prolonged the QTcF interval. DeltaDeltaQTcF prolongation was 25 +/- 8 ms after droperidol, significantly greater than the 17 +/- 10-ms prolongation with ondansetron (P = 0.014). The combination of droperidol and ondansetron significantly increased the mean maximal DeltaDeltaQTcF by 28 +/- 10 ms. The combination induced greater QTcF prolongation compared with ondansetron alone (P = 0.001), but not with droperidol alone (P = 0.33). There was no significant pharmacokinetic interaction between droperidol and ondansetron.
Conclusions: Under controlled conditions, both droperidol and ondansetron either alone or in combination induced significant marked QTc interval prolongation. However, the combination of both drugs did not significantly increase QTc prolongation compared with that induced by droperidol alone.

Background: Cannabinoid Hyperemesis Syndrome (CHS) is characterized by recurrent, paroxysmal episodes of nausea, vomiting, and abdominal discomfort in chronic cannabis users. Optimized CHS treatment data remain limited. Recent prospective evidence have demonstrated haloperidol superiority over ondansetron.

Background And Aims: Mammoplasty, a common cosmetic procedure involving breast augmentation and reduction surgeries, has gained global popularity. Recently, attention has shifted towards understanding the prevalence and significance of gastrointestinal (GI) symptoms following mammoplasty. This systematic review aims to consolidate existing literature to provide a comprehensive overview of the type and frequency of GI problems associated with various mammoplasty procedures.

The fourth Society for Academic Emergency Medicine (SAEM) Guidelines for Reasonable and Appropriate Care in the Emergency Department (GRACE-4) is on the topic of the emergency department (ED) management of nonopioid use disorders and focuses on alcohol withdrawal syndrome (AWS), alcohol use disorder (AUD), and cannabinoid hyperemesis syndrome (CHS). The SAEM GRACE-4 Writing Team, composed of emergency physicians and experts in addiction medicine and patients with lived experience, applied the Grading of Recommendations Assessment Development and Evaluation (GRADE) approach to assess the certainty of evidence and strength of recommendations regarding six priority questions for adult ED patients with AWS, AUD, and CHS. The SAEM GRACE-4 Writing Team reached the following recommendations: (1) in adult ED patients (over the age of 18) with moderate to severe AWS who are being admitted to hospital, we suggest using phenobarbital in addition to benzodiazepines compared to using benzodiazepines alone [low to very low certainty of evidence]; (2) in adult ED patients (over the age of 18) with AUD who desire alcohol cessation, we suggest a prescription for one anticraving medication [very low certainty of evidence]; (2a) in adult ED patients (over the age of 18) with AUD, we suggest naltrexone (compared to no prescription) to prevent return to heavy drinking [low certainty of evidence]; (2b) in adult ED patients (over the age of 18) with AUD and contraindications to naltrexone, we suggest acamprosate (compared to no prescription) to prevent return to heavy drinking and/or to reduce heavy drinking [low certainty of evidence]; (2c) in adult ED patients (over the age of 18) with AUD, we suggest gabapentin (compared to no prescription) for the management of AUD to reduce heavy drinking days and improve alcohol withdrawal symptoms [very low certainty of evidence]; (3a) in adult ED patients (over the age of 18) presenting to the ED with CHS we suggest the use of haloperidol or droperidol (in addition to usual care/serotonin antagonists, e.

Background: Droperidol is a butyrophenone, with antiemetic, sedative, anxiolytic, and analgesic properties. Although droperidol was once widely used in both emergency and perioperative settings, use of the medication declined rapidly after a 2001 U.S.

Objective: A randomised single-blind trial was undertaken in an adult ED population, comparing the effectiveness of droperidol 2.5 mg IV with ondansetron 8 mg IV for the treatment of nausea and vomiting.
Methods: Patients were randomly allocated to receive droperidol (n = 60) or ondansetron (n = 60).
