title: Post-operative headache--a multifactorial analysis.
abstract: ASA Grade I and II patients admitted for day-case urological surgery received no premedication or an oral dose of temazepam 10 mg. Anaesthesia was induced with methohexitone and maintained with nitrous oxide, oxygen and halothane or enflurane via a Mapleson A circuit. The incidence of post-operative headache was investigated by an independent observer. Eighty patients were studied (50 male and 30 female) of whom 32 (40%) had post-operative headaches. Post-operative headache was significantly correlated with female sex and frequent 'normal' headache occurrence. The lack of previous surgical experience was a significant risk factor and a loose insignificant association existed with age, the use of halothane and the presence of pre-operative headache. Temazepam premedication had no effect and was associated with significantly more patients complaining of feeling cold.
