Changes in anal pressure have been monitored during the induction of anaesthesia. Falls in pressure accompany loss of consciousness following bolus doses of commonly used intravenous and inhalational anaesthetic agents. Subsequent rises in pressure towards pre-anaesthetic levels are usually associated with the time taken to correct responses and initial recovery. Premedication, including anticholinergic drugs in conventional dosage, does not affect anal pressure.
在麻醉诱导期间监测了肛门压力的变化。静脉注射和吸入常用麻醉剂后，随着意识丧失，压力会下降。随后压力回升至麻醉前水平通常与恢复反应和初步恢复所需的时间有关。术前用药，包括常规剂量的抗胆碱能药物，不影响肛门压力。
