目的 观察酒石酸布托啡诺与芬太尼合用于术后静脉自控镇痛（PCIA）的效果及最佳混合比例。 方法 2010年8月－2011年1月100例妇科手术患者，随机分为5组，每组20例。均全身麻醉术后采用负荷量+持续背景剂量+PCIA方案镇痛。根据不同配方分为F组：芬太尼1 mg+生理盐水至100 mL；B组：酒石酸布托啡诺10 mg+生理盐水至100 mL；BFⅠ组：芬太尼0.6 mg+酒石酸布托啡诺3 mg+生理盐水至90 mL；BFⅡ组：芬太尼0.5 mg+酒石酸布托啡诺5 mg+生理盐水至100 mL；BFⅢ组：芬太尼0.3 mg+酒石酸布托啡诺6 mg+生理盐水至90 mL。观察术后各时点视觉模拟评分（VAS）及镇静评分，患者满意度以及不良反应情况。 结果 术后早期BFⅢ组和B组VAS评分大于F组；镇静评分B组大于F组；B组满意度优良率小于其余各组；恶心呕吐发生率F组高于BFⅠ组及BFⅡ组。 结论 酒石酸布托啡诺和芬太尼合用于PCIA，镇痛效果确切，不良反应发生率低。推荐配比：BFⅠ组和BFⅡ组。
Objective To analyze the risk factors for postoperative cognitive confusion in a surgical intensive care unit. Methods A total of 388 consecutive patients in Surgical Intensive Care Unit of General Hospital of PLA were retrospectively studied. We posed clinical questions according to the patients with older age and large dosage corticosteroid. Using “Postoperative cognitive confusion” and“Intensive Care” as key words, we searched for evidence from MEDLINE (1968-2004). Results We found 3.1% (10/388) of the patients developed postoperative cognitive confusion. Of the 10 postoperative cognitive confusion patients, 9 were over 65 years old. 6.6% (9/136) of the patients (≥ 65 years old) developed postoperative cognitive confusion. While 0.4%(1/252) of the patients (＜65 years old) developed postoperative cognitive confusion. Older age (≥ 65 years old) may induce more postoperative cognitive confusion (P＜0.05). While 7.0% (5/71) of the patients treated by large dose corticosteroids (≥1 000 mg) developed postoperative cognitive confusion. And 1.65% (5/317) of the patients received corticosteroid with large dosage (＜1 000 mg) developed postoperative cognitive confusion. Large dosage corticosteroid (≥1 000 mg) may induce more postoperative cognitive confusion (P＜0.05). Conclusion Older age (≥ 65 years old) and high dose corticosteroid (≥1 000 mg) may be the two main risk factors for postoperative cognitive confusion.
ObjectiveTo evaluate the clinical feasibility of retroperitoneal necrosectomy using percutaneous nephroscope in management of post-traumatic pancreatitis. MethodsSix patients with post-traumatic pancreatitis were treated by percutaneous nephroscopic necrosectomy in our hospital. ResultsThere were no operative mortality and morbidity except that 1 patient developed hemorrhage in 11 days after operation. ConclusionPercutaneous nephroscopic necrosectomy has the advantage of small operation wound, little postoperative discomfort, and preventing relaparotomy. It is an ideal method for treating post-traumatic pancreatitis.
