Background: Droperidol is a first-generation antipsychotic medication that has been used for various indications in the emergency department (ED); however, its use has been controversial due to reports of QT prolongation and the risk of torsades de pointes (TdP). The aim of the study is to evaluate the safety of droperidol administration in the ED.

Methods: This was a retrospective study, conducted at an academic level I trauma center.

Droperidol lowers the shivering threshold in rabbits.

J Anesth

December 2023

Department of Anesthesiology, Faculty of Medicine, University of Yamanashi, 1110 Shimokato, Chuo, Yamanashi, 409-3898, Japan.

Purpose: Perioperative shivering is common and can occur as a result of hypothermia or changes in the threshold of thermoregulation. Droperidol usage for anesthesia is currently limited to its sedative and antiemetic effects. We investigated the effects of high and low doses of droperidol on the shivering threshold in rabbits.

Background: To observe the effect of low-dose propofol combined with dexamethasone on the prevention of postoperative nausea and vomiting (PONV) in gynaecological day surgery under remimazolam-based general anesthesia.

Methods: A total of 120 patients, aged from 18 to 65 years old, American Society of Anesthesiologists grade I or II, were scheduled to undergo hysteroscopy under total intravenous anesthesia. The patients were divided into 3 groups (n = 40 each): dexamethasone plus saline group (DC group), dexamethasone plus droperidol group (DD group) and dexamethasone plus propofol group (DP group).

Background: Low-dose droperidol has been reported to suppress the amplitude of transcranial electrical motor-evoked potentials (TCE-MEPs), but no randomized controlled trials have been conducted to assess this. This randomized, double-blinded, placebo-controlled trial aimed to test the hypothesis that low-dose droperidol reduced TCE-MEP amplitudes.

Methods: Twenty female patients with adolescent idiopathic scoliosis, aged between 12 and 20 years, and scheduled to undergo corrective surgery were randomly allocated to receive droperidol (20 µg/kg) or 0.
