Comparison of propofol and thiopentone as anaesthetic agents for electroconvulsive therapy.
Propofol and thiopentone were compared as anaesthetic agents for electroconvulsive therapy in 31 patients on four occasions in a repeated measure crossover study. Discomfort on injection was significantly more common with propofol (51.6% of anaesthetics) compared to thiopentone (1.6% of anaesthetics). The duration of seizure was shorter with propofol in both treatments but there was significant drug-time interaction. Propofol gave a milder tonus and clonus during seizure when both treatments were considered together. The increase in systolic and diastolic arterial pressures and heart rate after treatment were significantly higher with thiopentone. Apnoea was significantly longer with propofol. The times to sitting up unaided and opening the eyes on command were the same for both drugs. The ability to walk 10 m 20 minutes after anaesthesia was significantly better with propofol (p less than 0.0001).
