In view of the current trend towards carrying out termination of pregnancy as day cases it is also important that the patient should be free from pain with a rapid recovery from anesthesia and a minimum of post operative sequalae. We compared the effects of three other anesthetic techniques for the termination of pregnancy in 100 healthy womes as day cases. 1) Anesthesia with thiopental sodium alone was associated with a high score of pain sensation(2±0.93) and with considerably rapid recovery(103±57.6 mins). 2) The combination of thiopental sodium and meperidine was associated with a lower score of pain sensation(1.58±0.8) and with rapidl recovery(101±56.4 mins). 3) Meperidine with diazepam was associated with the lowest score of pain sensation(1.4±0.69), but had prolonged recovery time(206±126 mins) twice that of other techniques. It was conclued that the combination A thiopental sodium and meperidine was the technique of choice for termination of pregnancy as day-cases.
