胃肠外科围手术期的液体治疗

外科液体治疗一直是关注的热点并存在争议。本文就液体治疗对术后肠道功能的影响、液体治疗对外科预后的影响和急性弥漫性腹膜炎围手术期液体治疗三方面进行讨论，应该注意在低灌注状况下胶体的补充和适当的晶／胶体比例。不同液体种类的选择在近年来的研究中未显示出远期效果的显著差异。关注2012SSC严重脓毒症及脓毒性休克指南更新中液体治疗新证据。

Perioperative fluid therapy of gastrointestinal surgery

Fluid therapy has been the focus of attention and dispute. In this paper, there are three aspects including postoperative bowel function, surgical prognosis, and acute diffuse peritonitis. Colloidal supplement and appropriate crystal /colloid ratio should he noted in low perfusion conditions. The different types of fluid in recent studies did not show a significant difference in the long term. The new evidence will be noted in fluid therapy among 2012 SSC Severe Sepsis and Septic Shock Guideline update（unpublished）.
