Acupuncture was given to patients before (preoperative-acupuncture group, PRE-ACU, n = 25) or after (postoperative-acupuncture group, POST-ACU, n = 25) operative removal of impacted mandibular third molars. Sixty patients did not receive acupuncture and participated as a control group (CG). All patients completed a questionnaire in order to characterize state tension and stress, degrees of neuroticism, extroversion, depression and psychosomatic disorders. We also recorded intraoperative discomfort and pain intensity, postoperative pain intensity and consumption of analgesics for 72 h. The PRE-ACU was significantly more tense following surgery and found the operative procedure more unpleasant than the other two groups. The PRE-ACU further rated intraoperative pain intensity higher than the CG and experienced higher pain intensity immediately postoperatively compared with POST-ACU and CG. Of the PRE-ACU patients 15/24 needed additional local anesthesia intraoperatively while none in the POST-ACU or CG requested extra lidocaine. Postoperatively patients in both PRE- and POST-ACU reported a higher total sum of pain scores (pain intensity) and the PRE-ACU consumed more analgesics compared with the CG. A significantly larger number of patients suffering from "dry socket" (a complication during wound healing) was found in both PRE- and POST-ACU compared with the CG. No correlation was found between assessed personality characteristics and reported postoperative pain/consumption of analgesics in any group and could thus not explain the observed differences between the groups. The reason for our unexpected "negative" findings is unclear but some hypothetical explanations are discussed.
对患者在拔除下颌阻生第三磨牙术前（术前针刺组，PRE - ACU，n = 25）或术后（术后针刺组，POST - ACU，n = 25）进行针刺。60例患者未接受针刺，作为对照组（CG）参与研究。所有患者均完成一份问卷，以描述状态紧张和压力、神经质程度、外向性、抑郁及身心障碍情况。我们还记录了术中不适和疼痛强度、术后疼痛强度以及72小时内的镇痛药消耗量。与其他两组相比，PRE - ACU组术后紧张程度明显更高，且觉得手术过程更不愉快。PRE - ACU组对术中疼痛强度的评分高于CG组，与POST - ACU组和CG组相比，术后即刻疼痛强度更高。PRE - ACU组中有15/24的患者术中需要额外的局部麻醉，而POST - ACU组和CG组均无人要求额外使用利多卡因。术后，PRE - ACU组和POST - ACU组患者报告的疼痛评分总和（疼痛强度）均较高，且与CG组相比，PRE - ACU组消耗的镇痛药更多。与CG组相比，PRE - ACU组和POST - ACU组中出现“干槽症”（伤口愈合期间的一种并发症）的患者数量明显更多。在任何一组中，评估的人格特征与报告的术后疼痛/镇痛药消耗量之间均未发现相关性，因此无法解释各组之间观察到的差异。我们意外的“负面”研究结果的原因尚不清楚，但讨论了一些假设性解释。
