目的 探讨层流手术室动态空气菌落数超标的高危因素。 方法 回顾分析2010年3月－2011年11月168台次特别洁净层流手术室动态空气样品细菌培养结果的资料，依据层流手术室动态环境下空气样品是否超过10个菌落形成单位（CFU）/m3将168例空气样品细菌培养的资料分别命名为超标组和正常组。超标组有56台次，正常组有112台次。将超标组与正常组就有关手术持续的时间、参与手术的医务人员数量、参观人数、手术过程中开门的次数、是否为污染手术、手术及麻醉设备是否在手术过程中有搬动、是否为接台手术、患者术前1 d是否更衣洗澡以及麻醉方式等因素进行分析比较。 结果 层流手术室动态空气菌落数超标与参观手术的人数、术中开门次数、手术类型、术中有无设备搬动及患者术前1 d是否进行更衣洗澡等因素有关（P＜0.05），而与手术持续时间、参加手术的人员数量、是否接台手术及麻醉方式等无关（P＞0.05）。 结论 参观手术的人数＞3人、术中开门次数＞10次、手术类型为污染手术、术中有设备搬动及患者术前1 d未进行沐浴更衣是层流手术室动态空气菌落数超标的高危因素。
ObjectiveTo analyze the risk factors of postoperative cognitive dysfunction (POCD) in elderly patients after abdominal surgery. MethodsThe clinical data of 2 286 patients over 60 years old after abdominal surgery were retrospectively analyzed, which were divided into non-POCD group with 2 248 patients and POCD group with 38 patients. The influencing factors of POCD in elderly patients after abdominal surgery, including the age, gender, anesthetic way, the premedication, cormobided with lung or heart disease, diabetes, jaundice, anemia or hypoproteinemia, the duration of surgery, and postoperative analgesia protocols, were analyzed between two groups. ResultsThe age, anesthetic way, cormobided with lung or heart disease, diabetes, jaundice, with or without continuous postoperative effective analgesia, and surgery duration over four hours were relevant with POCD (Plt;0.05), while gender, the premedication, and preexisted anemia or hypoproteinemia were not relevant with that (Pgt;0.05). ConclusionAge over 70 years, general anaesthesia, cormobided with lung or heart disease, diabetes, jaundice, surgery duration over four hours, and incomplete postoperative analgesia are the risk factors of POCD after abdominal surgery.
【摘要】 目的 探讨腹部非胃、十二指肠手术后胃瘫综合征（postoperative gastroparesis syndrome，PGS）发生的高危因素。 方法 回顾分析2004年9月-2010年3月2 559例腹部非胃、十二指肠术后患者的临床资料，将患者分为PGS组和非PGS组，其中PGS组23例，非PGS组2 536例。 结果 比较PGS组和非PGS组间年龄、性别、术后开始进食时间、手术持续时间、是否为肿瘤晚期、有无贫血低蛋白血症、既往有无腹部手术史、术后早期有无营养支持等因素，χ2值分别为:19.687、0.018、0.346、48.243、21.801、16.803、24.679、0.870，P值分别是:lt;0.01、gt;0.05、gt;0.05、lt;0.01、lt;0.01、lt;0.01、lt;0.01、gt;0.05。 结论 年龄gt;65岁、手术持续时间gt;4 h、肿瘤晚期、既往有腹部手术史及贫血低蛋白血症是腹部非胃、十二指肠手术后PGS发生的高危因素。【Abstract】 Objective To analyze the risk factors of postoperative gastroparesis syndrome (PGS) after non-gastroduodenal abdominal surgery. Methods We retrospectively analyzed the clinical data of 2 559 patients who underwent non-gastroduodenal abdominal surgeries in our hospital between September 2004 and March 2010. We divided them into the PGS group with 23 patients and the non-PGS group with 2 536 patients. Results By comparing the age, the gender, the starting time of eating after surgery, the duration of surgery, whether the patients had advanced cancer, whether anemia or hypoproteinemia existed, whether the patients had a history of previous abdominal surgery, and whether nutritional support was provided early after operation between the PGS group and the non-PGS group, we found that the chi-square value was 19.687, 0.018, 0.346, 48.243, 21.801, 16.803, 24.679, 0.870 and the P value waslt;0.01, gt;0.05, gt;0.05, lt;0.01, lt;0.01, lt;0.01, lt;0.01, gt;0.05 respectively. Conclusion Over 65 years of age, the duration of surgery over four hours, advanced cancer, the history of previous abdominal surgery and anemia or hypoproteinemia are the risk factors of PGS after non-gastroduodenal abdominal surgery.
