Randomized Controlled Trial Clinical Trial
[Narcotrend EEG monitoring during total intravenous anaesthesia in 4.630 patients].
The Narcotrend is a new EEG monitor designed to measure the hypnotic component of anaesthesia; however, a major clinical evaluation is still missing. This prospective multicentre study was designed to investigate the feasibility of Narcotrend monitoring in a large number of patients under different clinical conditions and to define its impact on recovery times after propofol-based total intravenous anaesthesia. ⋯ The EEG monitor Narcotrend can be used for adult patients of different ages and during various surgical procedures.Narcotrend monitoring facilitates a reduction of recovery times after propofol-based total intravenous anaesthesia,presumably by allowing for an individual titration of the propofol dosage. Moreover, it appears that the profile of recovery can be optimised when at the end of surgery,the propofol infusion is controlled to Narcotrend stage C instead of D, E, or F.

Randomized Controlled Trial Comparative Study Clinical Trial
[Recovery from anaesthesia and incidence and intensity of postoperative nausea and vomiting following a total intravenous anaesthesia (TIVA) with S-(+)-ketamine/propofol compared to alfentanil/propofol].
Opioids contribute to postoperative nausea and vomiting (PONV). An intraoperative analgesia with S-(+)-ketamine will make opioid administration dispensable and may reduce postoperative analgesic requirements. The aim of the study was to record the incidence and intensity of PONV following a total intravenous anesthesia (TIVA) with S-(+)-ketamine/propofol (K/P) or alfentanil/propofol (A/P) as well as recovery from anaesthesia. ⋯ A TIVA with K/P did not reduce PONV when compared to A/P, but prolonged recovery.
