Comparative StudyMode of delivery and lymphocyte beta 2-adrenoceptor density in parturients and newborns.
Twenty-six women with uncomplicated pregnancy at term were selected for the study. Nine had spontaneous vaginal delivery without medication, 8 elective caesarean section under epidural and 9 under general anaesthesia. ⋯ Vaginally delivered newborns have lower lymphocyte beta 2-adrenoceptor density than those delivered by caesarean section. A plausible explanation is the down-regulation of the beta 2-adrenoceptors during labour and delivery.
