Plasma beta-endorphin, pain and anxiety were measured in patients before, during, and 1 and 3 hours following oral surgery. Diazepam and fentanyl blocked the stress induced increase in plasma beta-endorphin experienced by patients administered placebo. Moreover, intra-operative anxiety and post-operative pain appear to constitute independent and possibly equipotent stimuli for release of pituitary beta-endorphin in humans.
在口腔手术前、手术期间以及术后1小时和3小时测量患者的血浆β-内啡肽、疼痛和焦虑水平。地西泮和芬太尼可阻断给予安慰剂患者所经历的应激诱导的血浆β-内啡肽增加。此外,术中焦虑和术后疼痛似乎是促使人体垂体释放β-内啡肽的独立且可能等效的刺激因素。
