        摘  要   目的 研究丙戊酸钠对严重烫伤合并海水浸泡延迟补液模型大鼠心脑损伤的保护作用。方法 将大鼠按照随机数字表法
        分为烫伤+延迟补液组(S组)、烫伤+海水浸泡+延迟补液组(SS组)、烫伤+海水浸泡+丙戊酸钠+延迟补液组(SSV组),每组60只。
        所有大鼠采用沸水水浴法建立35%总体表面积Ⅲ度烫伤模型。SS组和SSV组大鼠烫伤后立即浸泡于人工海水中(30 min),其中
        SSV组出水后即刻皮下注射丙戊酸钠300 mg/kg。各组烫伤后2 h按1/2 Parkland公式于30 min内静脉输入乳酸钠林格注射液进
        行延迟补液。记录大鼠死亡时间,计算各组大鼠平均生存时间和24 h生存率;分别于烫伤前和烫伤后0、2、5 h检测大鼠的平均动
        脉压(MAP)、心率(HR)、呼吸频率(RR)、直肠温度(RT)、动脉血pH、动脉血氧分压(PaO2 )、动脉血二氧化碳分压(PaCO2 )、实际碳
                  -
        酸氢根(HCO3 )、肌酸激酶同工酶(CK-MB)、神经元烯醇化酶(NSE);观察大鼠心脏、脑组织病理变化。结果 SS组大鼠24 h生存
        率(55%)较S组(90%)显著降低,而SSV组大鼠24 h生存率(75%)较SS组显著升高(P<0.05);与S组比较,SS组大鼠烫伤后0、2、5
        h的 MAP、RT、HR、pH、PaO2、HCO3 显著降低而CK-MB、NSE水平显著升高,烫伤后2、5 h的PaCO2显著升高,烫伤后0、2 h的RR
                                   -
                                                                                   -
        显著降低(P<0.05);与 SS 组比较,SSV 组大鼠在烫伤后 2、5 h 的 MAP、RT、HR、pH、PaO2、HCO3 显著升高而 PaCO2和 CK-MB、
        NSE水平显著降低,烫伤后2 h的RR显著升高(P<0.05)。在烫伤后2、5 h,SS组大鼠心脏、脑组织损伤程度较S组明显加重;SSV
        组大鼠心脏、脑组织病理损伤程度较SS组明显减轻。结论 严重烫伤大鼠合并海水浸泡后,皮下注射丙戊酸钠能保护大鼠心脑功
        能,改善生命体征和血气指标,延长其存活时间,提高其生存率。

        ABSTRACT    OBJECTIVE To study the protective effects of valproic acid on cardiac and cerebral injury in rats subjected to
        severe scalding combined with seawater immersion injury with delayed fluid replacement. METHODS The rats were divided into
        scalding+delayed fluid replacement group(group S),scalding+seawater immersion+delayed fluid replacement group(group SS),
        scalding+seawater immersion+valproic acid+delayed fluid replacement group(group SSV)according to random number table,with
        60 rats in each group. All groups were subjected to 35%total body surface area third-degree full-thickness scalding with boiled
