摘 要:目的观察不同潮气量及呼气末正压(PEEP)机械通气对复苏后综合征患者的影响,探讨心肺复苏后的机械通气策略。方法选择我院2008年12月—2011年12月收治的心搏骤停后复苏后综合征患者36例,采用数字表法随机分为A1、A2、A3、B1、B2、B3组,每组6例。A1组采用低潮气量(6 ml/kg)+低PEEP(3 cm H2O),A2组采用低潮气量(6 ml/kg)+中等PEEP(6 cm H2O),A3组采用低潮气量(6 ml/kg)+高PEEP(12 cm H2O),B1组采用常规潮气量(10 ml/kg)+低PEEP(3 cm H2O),B2组采用常规潮气量(10 ml/kg)+中等PEEP(6 cmH2O),B3组采用常规潮气量(10 ml/kg)+高PEEP(12 cm H2O)。自主循环恢复后开始计时,观察并记录各组患者1 h、6 h、12 h、24 h时氧合指数(OI)、血气分析〔pH值、动脉血氧分压(PO2)、二氧化碳分压(PCO2)〕、中心静脉压(CVP)、维持基础平均动脉压(MAP)所需多巴胺剂量、心率(HR)、肝肾功能〔丙氨酸氨基转移酶(ALT)、总胆红素(TBiL)、肌酐(Cr)〕、格拉斯哥昏迷量表评分(GCS评分)。结果 (1)各组组内24 h时PO2、OI与1 h、6 h、12 h时比较,差异均有统计学意义(P<0.05);A1组与A2、A3组,B1组与B2、B3组各时点PO2、OI比较,差异均有统计学意义(P<0.05)。(2)各组6 h时CVP最高、维持基础MPA所需多巴胺剂量最高、HR最快,12~24 h时CVP逐渐降低、维持基础MPA所需多巴胺剂量逐渐降低、HR逐渐减慢,与1 h、24 h时比较,差异均有统计学意义(P<0.05)。(3)各组1 h时ALT、TBiL、Cr水平与12 h、24 h时比较,差异均有统计学意义(P<0.05);各组pH值在6 h时均升高至正常,在6 h后又逐渐下降,A2组1 h、24 h时pH值与6 h时比较,差异有统计学意义(P<0.05)。A2组12 h、24 h时pH值、ALT、TBiL、Cr水平与其他各组比较,差异均有统计学意义(P<0.05)。(4)各组24 h内GCS评分均处于较低水平,A2组1 h时GCS评分与12 h、24 h时比较,差异均有统计学意义(P<0.05);A2组12 h、24 h时GCS评分与其他各组比较,差异均有统计学意义(P<0.05)。�Objective To compare the effect of different tidal volumes (TV) and mechanical ventilation (MV) with positive end - expiratory pressure (PEEP) on patients with post - resuscitation syndrome ( PRS), and discuss the ventilation strategy in cardiopulmonary resuscitation (CPR). Methods Thirty - six patients with PRS after cardiac arrest admitted in our hospital between December 2008 and December 2011 were randomly and evenly divided into group A1 , group A2 , group A3 , group B1, group B2 and group B3. Low TV (6 ml/kg) plus low PEEP (3 cm H2O) was applied to patients of group A1 , low TV (6 ml/kg) plus medium PEEP (6 cm H2O) to group A2, low TV (6 ml/kg) plus high PEEP (12 cm H2O) to group A3, routine TV (10 ml/kg) plus low PEEP (3 cm H2O) to group B1, routine TV (10 ml/kg) plus medium PEEP (6 cm H2O) to group B2, and routine TV ( 10 ml/kg) plus high PEEP ( 12 cm H2O) to group B3. Timing was started after res- toration of spontaneous circulation (ROSC). Patients'oxygenation index (OI), blood gas analysis (pH, PO2, PCO2 ), cen- tral venous pressure (CVP), dopamine dose for basal MAP maintenance, heart rate (HR) , hepatic and renal function (ALT, TBiL, Cr), and Glasgow coma score (GCS) were measured and recorded at 1 h, 6 h, 12 h and 24 h. Results PO2 and OIat 24 h was significantly lower than that of 1 h, 6 h and 12 h in all groups (P 〈0. 05). PO2 and OI at all time points in group A1 was significantly lower than that of group A2 and A3 , and that of group B1 was lower than that of group B2 and B3 ( P 〈 0. 05). Dopamine dose for basal MAP maintenance, HR and CVP reached the highest at 6 h and decreased gradually during 12 - 24 h in all groups. Dopamine dose for basal MAP maintenance, HR and CVP at 6 h in all groups was significantly different from that of 1 h and 24 h (P 〈0. 05). ALT, TBiL, Cr at 12 h and 24 h was higher than that of 1 h in all groups (P 〈0. 05). The pH increased to normal level at
