摘要
目的 比较不同比例的晶体液与胶体液(晶胶比)早期液体复苏对小儿重症急性胰腺炎(SAP)血流动力学及预后的影响.方法 48例SAP患儿急性期早期给予对症支持治疗,并给予早期液体复苏,以晶胶比3为界,将患儿按数字表法随机分为低晶胶比组和高晶胶比组,各24例.观察复苏前(T0)及复苏结束后即刻(T1)、24 h(T2)、48 h(T3)血流动力学指标的变化,记录两组患儿的补液量、并发症发生率及病死率.结果 两组患儿T1、T2、T3时点的中心静脉压(CVP)、心指数(CI)、血管外肺水指数(ELWI)及胸腔内血容量指数(ITBI)均较同组T0时点明显升高(P值均<0.05).除高晶胶比组的ELWI在T2时点较低晶胶比组明显升高外[(14.9±4.2)ml/m2比(11.9 ±3.1)ml/m2,P<0.05)],其他时点两组血流动力学各指标的差异均无统计学意义.高晶胶比组24 h总补液量、晶体液量、第三间隙液体潴留量、晶胶比分别为(4931±518)、(3963±552)、(2619±367) ml及4.47±0.41,低晶胶比组分别为(4436±547)、(3348±421)、(1711±278) ml及2.31±0.37,高晶胶比组较低晶胶比组均显著升高(P值均<0.05),但高晶胶比组24 h胶体液量为(922±452) ml,显著低于低晶胶比组的(1117±390) ml(P<0.05).高晶胶比组机械通气率、心功能不全发生率、多器官功能衰竭发生率分别为58.3%、33.3%、25.0%,均显著高于低晶胶比组的25.0%、8.24%、4.12%(P值均<0.05),但两组病死率无显著差异.结论 小儿SAP采用低晶胶比液体进行限制性液体复苏,可有效改善血流动力学,减轻液体潴留,改善患儿预后.
Objective To investigate the impact of fluid resuscitation with different crystalloid-colloid ratios on hemodynamics and prognosis in pediatric patients with severe acute pancreatitis (SAP). Methods Forty-eight patients with pediatric SAP were given supportive therapy and fluid resuscitation in the early acute phase. Patients were randomly divided into low crystalloid-colloid ratio group and high erystalloid-colloid ratio group according to erystalloid-colloid ratio (3:1 ) as the cutoff value, with 24 patients in each group. Hemodynamic parameters were observed at the time point of before fluid resuscitation ( T0), and 0 ( T1 ) , 24 (T2) , 48 ( T3 ) hours after resuscitation, the quantity of fluid resuscitation, complications and mortality of the two groups were compared. Results Central venous pression(CVP) , Cardiac index (CI) , Extravascular lung water index (ELWI) ,Intrathoracic blood volume index (ITBI) at T1, T2, T3 were significantly higher than those at TO in both groups ( P 〈 0.05 ). The ELWI of high crystalloid-colloid ratio group at T2 was significantly higher than that in low erystalloid-colloid ratio group [( 14.9± 4.2)ml/m2 vs (11.9± 3.1)ml/m2, P 〈 0.05 ) ] , but the other hemodynamic parameters of both groups were not significantly different. The 24 h total volume of infused fluid, 24 h total volume of colloid, 24 h total amount of fluid retention in the third space, 24 h crystalloid-colloid ratio was ( 4931 ± 518 ), ( 3963 ± 552 ), ( 2619 ± 367 ) ml and 4.47 ± 0.41 in high crystalloid-eolloid ratio group, the corresponding values in low crystalloid-eolloid ratio group were (4436 ± 547) , (3348 ± 421 ) , ( 1711 ± 278 ) ml and 2.31 ± 0.37, the values in high crystalloid-colloid ratio group were significantly higher than those in low erystalloid-colloid ratio group (P 〈 0.05 ). However, 24 h total volume of colloid in high crystalloid-colloid ratio group was significantly lower than that in low crystalloid-colloid ratio group [ (922 ± 452) ml vs ( 1117 ± 390) ml, P 〈 0.05 ]. The incidence of mechanical ventilation rate, cardiac insufficiency, MODS was 58.3%, 33.3%, 25.0% in high crystalloid-colloid ratio group, which were significantly higher than those in low crystalloid-colloid ratio group (25.0%, 8.24%, 4.2%, P 〈 0.05 ), but the mortality was not significantly different. Conclusions A low crystalloid-colloid ratio should be considered for controlled fluid resuscitation in pediatric SAP patients in order to effectively improve hemodynamics, reduce fluid retention, and improve the prognosis.
