Randomized Controlled Trial Comparative Study Clinical TrialConscious sedation and cardiorespiratory safety during colonoscopy.
Cardiorespiratory events during colonoscopy are common. The effect of sedative premedication on cardiorespiratory parameters during colonoscopy has not been studied in controlled, prospective trials. ⋯ Premedication with midazolam induced a statistically significant decrease in arterial oxygen saturation and increased the risk for hypotension. However, colonoscopy proved to be a safe procedure both with and without sedation.
