Abstract

Assess to impact hypothermia on ABP, CPP, ICP and cerebral autoregulation. Material and methods. 14 patients with TBI (GOS<9) underwent hypothermia by Thermogard system within 32-35 °C (Zoll, USA). ICP was measured intraparenchymal by Codman sensor. Cerebral autoregulation was estimated by correlation coefficient Prx (Soft ICM Plus, Cambridge, UK). Temperature was measured in urinary bladder. There were selected five time periods: 1 - phase of initial state, 2 - phase of induction hypothermia, 3 - phase of hypothermia, 4 - phase of rewarming, 5 - phase after finishing hypothermia. All data preset as Mediana (min; max). Stat analysis was perfomed using Soft Statistica 10.0. Results. Phase 1 lasted nearly 7 (2; 12) h, ABP 94 (81; 102), CPP - 73 (52; 87), ICP 27 (16; 45) mm Hg, Prx 0,25 (-0,15; 0,7), temperature 38,2 °C (37; 39,8). Phase 2: 5 (2; 12) h, ABP 95 (85; 114), CPP 80 (65; 96), ICP 18 (10; 22) mm Hg, Prx -0,055 (-0,15; 0,7), temperature 35,2 °C (34,5; 35,5). Phase 3: 55 (20; 100) h, there were not significant changed ABP, CPP, Prx, ICP 15 (10; 18) mm Hg, temperature was 33,5 °C (32; 34,7). Phase 4: 17 (8; 24) h, ABP 90 (70; 100), CPP 77 (55; 85), ICP 15 (9; 27) mm Hg and Prx 0,2 (-0,2; 0,32). Temperature 36,9 °C (35,9; 38,5). Phase 5: 20 (6; 240) h, ABP 87(53; 110), CPP 72 (47; 107), ICP 17 (10; 32) mm Hg and Prx 0,2 (-0,2; 0,6). Temperature 37,7 °C (36,7; 39,0). Conclusion. Hypothermia is an effective method for correction of intracranial hypertension. Hypothermia can use as a additional option of intensive care during refractory intracranial hypertension. Rewarming phase is the most dangerous time on the re-development of intracranial hypertension and disruption of autoregulation.

摘要

评估体温过低对动脉血压(ABP)、脑灌注压(CPP)、颅内压(ICP)和脑自动调节的影响。材料与方法。14例格拉斯哥预后评分(GOS)<9分的创伤性脑损伤(TBI)患者通过美国佐尔公司的Thermogard系统在32 - 35°C进行体温过低治疗。通过Codman传感器进行脑实质内颅内压测量。通过相关系数Prx(英国剑桥Soft ICM Plus公司)评估脑自动调节。在膀胱测量体温。选取五个时间段:1 - 初始状态阶段,2 - 体温过低诱导阶段,3 - 体温过低阶段,4 - 复温阶段,5 - 体温过低结束后阶段。所有数据表示为中位数(最小值;最大值)。使用Soft Statistica 10.0进行统计分析。结果。第1阶段持续约7(2;12)小时,动脉血压94(81;102),脑灌注压 - 73(52;87),颅内压27(16;45)毫米汞柱,Prx 0.25(-0.15;0.7),体温38.²°C(37;39.8)。第2阶段:5(2;12)小时,动脉血压95(85;114),脑灌注压80(65;96),颅内压18(10;22)毫米汞柱,Prx -0.055(-0.15;0.7),体温35.²°C(34.5;35.5)。第3阶段:55(20;100)小时,动脉血压、脑灌注压、Prx无显著变化,颅内压15(10;18)毫米汞柱,体温为33.5°C(32;34.7)。第4阶段:17(8;24)小时,动脉血压90(70;100),脑灌注压77(55;85),颅内压15(9;27)毫米汞柱,Prx 0.2(-0.2;0.32)。体温36.9°C(35.9;38.5)。第5阶段:20(6;240)小时,动脉血压87(53;110),脑灌注压72(47;107),颅内压17(10;32)毫米汞柱,Prx 0.2(-0.2;0.6)。体温37.7°C(36.7;39.0)。结论。体温过低是纠正颅内高压的有效方法。体温过低可作为难治性颅内高压时重症监护的额外选择。复温阶段是颅内高压再次发生和自动调节破坏最危险的时期。
