乳腺癌游离皮瓣乳房重建术后的麻醉管理

背景与目的：围术期的麻醉管理对游离皮瓣乳房重建术成功与否至关重要。该研究拟探讨游离腹壁下深血管穿支皮瓣(deep inferior epigastric perforator flap，DIEP)乳房重建术中的补液、血流动力学以及体温管理。方法：收集自2011年6月—2015年12月共126例接受DIEP乳房重建术的患者资料。回顾性分析患者术后并发症、术中补液速度、以下时点的平均动脉血压(mean arterial blood pressure，MAP)和中心体温：麻醉诱导前(T0)、皮瓣切取完毕移植前(T1)、皮瓣血管吻合完毕后15 min(T2)，手术结束(T3)。结果：9例患者发生皮瓣危象，其中7例解救成功，2例失败。术中平均补液速度为(5.44±1.66)(mL·kg-1)/h。T0、T1、T2和T3的MAP分别为(87.45±8.90)、(74.19±8.63)、(74.60±8.71)和(79.62±7.88) mmHg。T0、T1、T2和T3的中心体温分别为(36.69±0.14)、(36.36±0.18)、(36.27±0.14)和(36.21±0.15)℃。结论：研究者应该针对游离皮瓣乳房重建术中的补液、血流动力学以及体温管理建立规范化标准，以优化皮瓣转归。

Intraoperative anesthetic management in breast cancer patients undergoing free flap breast reconstruction

Background and purpose:Perioperative anesthetic management is thought to be critical to the success of free flap breast reconstruction. The purpose of this study was to discuss intraoperative fluid, hemodynamic and temperature management in patients undergoing deep inferior epigastric perforator (DIEP) flap breast reconstruction.Methods:From Jun. 2011 to Dec. 2015, 126 patients underwent DIEP lfap breast reconstruction. Postoperative complications were reviewed. Intraoperative fluid infusion rate was analyzed. Mean arterial blood pressure (MAP) and core temperature were measured before induction (T0), after lfap elevation but before lfap transfer (T1), 15 min after flap revascularization (T2), and at the end of surgery (T3).Results:Nine patients developed flap compromised: 7 were salvaged and 2 failed. The mean intraoperative lfuid infusion rate was (5.44±1.66) (mL?kg-1)/h. MAP at T0, T1, T2 and T3 were (87.45±8.90), (74.19±8.63), (74.60±8.71) and (79.62±7.88) mmHg, respectively. Core temperature at T0, T1, T2 and T3 were (36.69±0.14), (36.36±0.18), (36.27±0.14) and (36.21±0.15)℃, respectively. Conclusion:Standard practice focusing on intraoperative lfuid management, hemodynamic adjustment and temperature control in microsurgical reconstruction of the breast should be established to further improve free lfap outcome.
