目的 探讨双管喉罩与气管插管用于全身麻醉妇科腹腔镜手术的安全性和可行性。 方法 2009年1月-5月择期妇科腹腔镜手术患者60例，ASAⅠ～Ⅱ级，随机分为喉罩组（P组）和气管插管组（T组）。记录入室基础值（T0），置罩（管）前（T1），置罩（管）后即刻（T2），置罩（管）后5 min（T3 ），拔除罩（管）即刻（T4），拔除罩（管）后5 min（T5）的收缩压（systolic pressure, SBP），舒张压（diastolic pressure, DBP），心率（heart rate, HR）和脉搏血氧饱和度（pulse oxygen saturation, SpO2），喉罩和气管插管控制呼吸时气腹前后不同时段的气道峰压（airway. maximum pressure, Pmax），潮气量（vital volume, VT）和呼气末二氧化碳分压（end tidal CO2, PETCO2）。记录插罩（管）成功率，及相关并发症。 结果 T2时T组SBP，DBP和HR显著高于P组（P＜0.05），两组术中通气均满意；Pmax，VT和PETCO2组间比较各时点无差异（P＞0.05）。气腹后Pmax和PETCO2组内比较均高于气腹前，差异有统计学意义（P＜0.05）。置罩（管）成功率组间比较差异无统计学意义，拔罩（管）期及术后24 h并发症，喉罩组明显低于气管导管组，差异显著（P＜0.05）。 结论 双管喉罩用于全麻妇科腹腔镜手术通气效果满意，安全可行。
Objective To investigate the effect of accuracy of phase 3 Oxford prosthesis positioning on short-term effectiveness of unicompartmental knee arthroplasty (UKA). Methods The clinical data of 26 patients (26 knees) who were treated with UKA between September 2015 and November 2015 was retrospectively analyzed. The single-peg Oxford prosthesis was implanted in 15 patients (single-peg group), and twin-peg Oxford prosthesis was implanted in 11 patients (twin-peg group). There was no significant difference in gender, age, body mass index, Kellgren-Lawrence grading, and preoperative Hospital for Special Surgery (HSS) scores between 2 groups (P>0.05). HSS, knee society score (KSS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and Oxford knee score (OKS) were used to evaluate the knee function. Radiographic criteria for Oxford UKA was used to evaluate the prosthesis position. The reason and treatment of bearing dislocations were recorded. Results All patients were followed up with mean follow-up time of 26.2 months in single-peg group (range, 24-27 months) and 25.2 months in twin-peg group (range, 24-26 months). The bearing dislocation occurred in 2 cases of twin-peg group during follow-up. At last follow-up, there was no significant difference in HSS, WOMAC, OKS, and KSS scores between 2 groups (P>0.05). There was no significant difference in radiographic scores of femoral component, tibial component, and overall components between 2 groups (P>0.05). No significant correlation was found between radiographic scores and postoperative functional outcome in 2 groups (P>0.05). Conclusion Within a safe range, the accuracy of phase 3 Oxford prosthesis positioning has limited influence on the short-term functional outcome.
