Intraoperative hypovolemia is common and is a potential cause of organ dysfunction, increased postoperative morbidity, length of hospital stay, and death. The objective of this prospective, randomized study was to assess the effect of goal-directed intraoperative fluid administration on length of postoperative hospital stay.
One hundred patients who were to undergo major elective surgery with an anticipated blood loss greater than 500 ml were randomly assigned to a control group (n = 50) that received standard intraoperative care or to a protocol group (n = 50) that, in addition, received intraoperative plasma volume expansion guided by the esophageal Doppler monitor to maintain maximal stroke volume. Length of postoperative hospital stay and postoperative surgical morbidity were assessed.
Groups were similar with respect to demographics, surgical procedures, and baseline hemodynamic variables. The protocol group had a significantly higher stroke volume and cardiac output at the end of surgery compared with the control group. Patients in the protocol group had a shorter duration of hospital stay compared with the control group: 5 +/- 3 versus 7 +/- 3 days (mean +/- SD), with a median of 6 versus 7 days, respectively ( = 0.03). These patients also tolerated oral intake of solid food earlier than the control group: 3 +/- 0.5 versus 4.7 +/- 0.5 days (mean +/- SD), with a median of 3 versus 5 days, respectively ( = 0.01).
Goal-directed intraoperative fluid administration results in earlier return to bowel function, lower incidence of postoperative nausea and vomiting, and decrease in length of postoperative hospital stay.
术中低血容量很常见,是器官功能障碍、术后发病率增加、住院时间延长及死亡的潜在原因。这项前瞻性随机研究的目的是评估目标导向性术中液体输注对术后住院时间的影响。
100例预计失血超过500ml的择期大手术患者被随机分为对照组(n = 50),接受标准术中护理;或方案组(n = 50),除接受标准术中护理外,还接受食管多普勒监测仪引导下的术中血浆容量扩充以维持最大每搏输出量。评估术后住院时间和术后手术并发症。
两组在人口统计学、手术操作和基线血流动力学变量方面相似。与对照组相比,方案组在手术结束时每搏输出量和心输出量显著更高。方案组患者的住院时间比对照组短:5±3天对7±3天(均值±标准差),中位数分别为6天对7天(P = 0.03)。这些患者也比对照组更早耐受固体食物的口服摄入:3±0.5天对4.7±0.5天(均值±标准差),中位数分别为3天对5天(P = 0.01)。
目标导向性术中液体输注可使肠功能更早恢复,术后恶心和呕吐的发生率降低,并缩短术后住院时间。
