A survey of anaesthetic techniques used for caesarean section in the UK in 1997.
A prospective survey of anaesthesia for caesarean section was performed for the year 1 January to 31 December, 1997. Two hundred and fifty maternity hospitals were sent questionnaires from which 129 responses were obtained. The data provided information on anaesthesia for 60 455 caesarean sections. ⋯ There was a wide range of regional anaesthesia use among the units, varying from an overall rate of 95% at one extreme to 41% at the other. Similarly, there was a wide range of conversion of regional anaesthesia to general anaesthesia, varying from 0% to 88%. Overall, 10.6% of the general anaesthetics were the result of regional to general anaesthesia conversion.

Paraesthesiae and nerve damage following combined spinal epidural and spinal anaesthesia: a pilot survey.
Concern has been expressed that recent changes in techniques of spinal blockade may have resulted in an increase in frequency of neurological sequelae. In order to make preliminary enquiries about anaesthetists' recent experiences of neurological sequelae following spinal and combined spinal-epidural anaesthesia, a questionnaire, covering numbers of procedures, needles used and any neurological problems that had been encountered, was sent to the anaesthetist in charge of each obstetric centre on the Royal College of Obstetricians and Gynaecologists' United Kingdom list. ⋯ Whitacre atraumatic needle (odds ratio 1.40, confidence interval 0.64 to 3.08). A prospective survey, or better still, randomisation would be needed to verify these findings.

Randomized Controlled Trial Clinical TrialThe effect of prophylactic glycopyrrolate on maternal haemodynamics following spinal anaesthesia for elective caesarean section.
We conducted a randomised controlled trial to compare the severity of hypotension and ephedrine requirements following spinal anaesthesia for elective caesarean section in women pretreated with either i.v. glycopyrrolate 4.0 microg/kg (group G) or saline (group S). Data were analysed using sequential analysis which allowed us to terminate the study after data from 40 patients had been analysed (20 in each group). ⋯ Intra-operative heart rate increased by a greater amount in group G than in group S (58 +/- 26% vs 35 +/- 21% mean +/- SD;P = 0.002) and there was a greater incidence of dry mouth (75% vs 15%;P = 0.0006) but no difference in the incidence of nausea and vomiting (30% vs 50%;P = 0.33). Pretreatment with glycopyrrolate did not confer an advantage in this study.
