Comparative Study[Sterilization of women. Waiting lists, surgical techniques and type of anesthesia].
The surgical and anaesthesiological techniques of tubal sterilization in Norway were studied by means of questionnaire. All hospitals returned the questionnaire. 94% of the operations were performed by gynaecologists, and in 99% of the cases by bipolar or endothermal laparoscopy. ⋯ There were significant regional differences in sterilization rates and waiting time. We found no simple relation between sterilization technique and waiting lists.

Comparative Study
Neonatal wellbeing after elective caesarean delivery with general, spinal, and epidural anaesthesia.
A comparison was made of the acid-base and Apgar status of neonates following general (n = 34), spinal (n = 28) and epidural (n = 23) anaesthesia for elective caesarean section. Neonates delivered following spinal anaesthesia were more acidaemic (pH = 7.249) (P < 0.05) than those delivered following epidural (pH = 7.291) or general anaesthesia (pH = 7.296) despite measures taken to minimize hypotension. ⋯ The difference between epidural and general anaesthesia was significant (P < 0.05). Using these two measures of neonatal wellbeing, epidural anaesthesia provided the most favourable outcome.

Randomized Controlled Trial Comparative Study Clinical Trial
[Acoustic evoked potentials of medium latency. Anesthesia induction with S-(+)-ketamine versus ketamine racemate].
Mid-latency auditory evoked potentials (MLAEP) reflect the primary cortical processing of auditory stimuli. They are widely suppressed during general anaesthesia with volatile anaesthetics. Under ketamine, in contrast, they seem to be preserved, which has been interpreted as indicating insufficient suppression of consciousness during ketamine anaesthesia. ⋯ MLAEP do not change in amplitude or latency during induction of general anesthesia with S-(+)-ketamine or ketamine-racemat. Primary cortical processing of auditory stimuli seems to preserved under S-(+)-ketamine and ketamine-racemat. This must be viewed in connection with dreams and hallucinations and could be interpreted as inadequate suppression of auditory information processing during general anaesthesia with S-(+)-ketamine and ketamine-racemat.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective randomised study of local versus general anaesthesia for cataract surgery.
One hundred and sixty-nine patients (aged 65-98 years) were randomised to receive either local or general anaesthesia for cataract surgery. Cognitive function was assessed using a battery of psychometric tests performed pre-operatively, and at 24 h, 2 weeks and 3 months postoperatively. ⋯ Pulse rate and blood pressure were stable in the local anaesthetic group compared with the general anaesthetic group where marked fluctuations were noted; 61% of patients in the general anaesthetic group experienced falls in systolic blood pressure greater than 30% of the pre-induction value. No evidence of long-term postoperative cognitive dysfunction was detected and there was no significant difference between the performances of the two groups.
