目的 探討雙管喉罩與氣管插管用于全身麻醉婦科腹腔鏡手術的安全性和可行性。 方法 2009年1月-5月擇期婦科腹腔鏡手術患者60例，ASAⅠ～Ⅱ級，隨機分為喉罩組（P組）和氣管插管組（T組）。記錄入室基礎值（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）的收縮壓（systolic pressure, SBP），舒張壓（diastolic pressure, DBP），心率（heart rate, HR）和脈搏血氧飽和度（pulse oxygen saturation, SpO2），喉罩和氣管插管控制呼吸時氣腹前后不同時段的氣道峰壓（airway. maximum pressure, Pmax），潮氣量（vital volume, VT）和呼氣末二氧化碳分壓（end tidal CO2, PETCO2）。記錄插罩（管）成功率，及相關并發癥。 結果 T2時T組SBP，DBP和HR顯著高于P組（P＜0.05），兩組術中通氣均滿意；Pmax，VT和PETCO2組間比較各時點無差異（P＞0.05）。氣腹后Pmax和PETCO2組內比較均高于氣腹前，差異有統計學意義（P＜0.05）。置罩（管）成功率組間比較差異無統計學意義，拔罩（管）期及術后24 h并發癥，喉罩組明顯低于氣管導管組，差異顯著（P＜0.05）。 結論 雙管喉罩用于全麻婦科腹腔鏡手術通氣效果滿意，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.
