Comparison of prophylactic use of midazolam, ketamine, and ketamine plus midazolam for prevention of shivering during regional anaesthesia: a randomized double-blind placebo controlled trial

摘要

Background Regional anaesthesia, like general anaesthesia, influences the thermoregulatory process. The aim of the present study was to compare the efficacy of low-dose prophylactic midazolam with that of placebo, ketamine, and a combination of ketamine and midazolam in the prevention of shivering caused by regional anaesthesia.
