摘 要:目的观察颅内高压患者术中应用3%高渗盐水(HS)与20%甘露醇(M)的血流动力学及内环境的变化。方法60例颅内高压患者随机分为HS组(n=30)和M组(n=30),观察开始用药时(T0)、用药后(T1)、5min(T2)、15min(T3)、30min(T4)、45min(T5)、60min(T6)、90min(T7)、120min(T8)的心率(HR)、平均动脉压(MAP)、每搏量指数(SVI)、每搏量变异度(SVV)、中心静脉压(CVP)、体循环血管阻力指数(SVRI)和尿量,Tn、L时点桡动脉血pH值、Na+、K+、Ca+、血乳酸(BLA)。结果(1)HS组:与Tn比较,输注后T1-T8时点SVV降低,SVI、CVP、MAP值升高(P〈0.05);HR值T1时点升高,R—T8时点降低(P〈0.05);SVRI值T1-T5时点降低(P〈0.05)。(2)与Tn比较,HS组B时点Na+值升高,BLA值降低(P〈0.05);两级比较,R时点组间Na+值比较差异有统计学意义(P〈0.05)。(3)与M组比较,L—B时点SVV、SVI、CVP、MAP、HR、SVRI差异有统计学意义(P〈0.05)。(4)各时点M组尿量多于HS组(P〈0.05)。结论颅内高压患者术中输注3%HS在维持血流动力学稳定和改善内环境方面优于20%M。Objective To observe the changes in hemodynamics and internal environments after application Of 3% hypertonic saline (HS) vs 20% mannitol (M) in intracranial hypertensive patients. Methods Sixty patients with intracranial hypertension were randomly allocated to HS group ( n = 30) and M group (n = 30), receiving 3% HS and 20% M respectively. Heart rate (HR), mean arterial pressure (MAP) , stroke volume index (SVI) , stroke volume variation (SVV) , central venous pressure (CVP) , systemic vascular resistance index (SVRI) and urine output were measured before injection ( To ) , immedi- ate (T1), 5 min (T2), 15 min (T3), 30 min (T4), 45 min (T5), 60 min (T6), 90 rain (TT), and 120 min (T8 ) after injection. The radial artery blood was collected for measuring the pH, Na+ , K+, Ca2 + , blood lactate (BLA) at To and T8. Results ( 1 ) In HS group, the levels of SYV were decreased, and those of SVI, CVP and MAP increased at T1 -T8 as compared with To ( P 〈 0.05 ) ; HR was increased at TI and decreased at T6-T8 ( P 〈 0. 05 ) ; SVRI was decreased at T1 -T5 ( P 〈 0. 05 ) ; ( 2 ) As compared with To, the levels of blood Na + were increased and BLA contents decreased at T, in HS group ( P 〈 0.05 ) ; (3) There was significant difference in the levels of SVV, SVI, CVP, MAP, HR and SVRI between HS group at T5-T8 and M group ( P 〈 0. 05 ) ; (4) The hydrouria in M group at T1 -T8 was greater than in HS group (P〈0.05). Conclusions 3% HS is superior to 20% M in maintaining circulation stability and improving internal environments during operation in patients with intracranial hypertension.
