[Electrostimulation anaesthesia and neurolept anaesthesia for cholecystectomy. A comparative study (author's transl)]

In 26 patients, undergoing cholecystectomy under electrostimulation anaesthesia (ESA) (n = 14) and neurolept anesthesia (NLA) (n = 12) the effects on consumption of anaesthetic agents, mean arterial pressure, heart rate, blood gases, lung function, serum cortisol and awareness are compared. Consumption of anaesthetic agents was 21.6 per cent in ESA compared to 100 per cent in NLA. Mean arterial pressure, heart rate and serum cortisol were elevated in ESA compared to NLA, probably due to elevated stress. Awareness 4 hours after anaesthesia was higher in ESA, probably due to less persistence of anaesthetics. Blood gases 1 hour after operation were slightly better after ESA, as also were forced vital capacity and peak flow one day after operation. The results are discussed.
