摘　　要：目的分析广西境内两种常见神经毒类毒蛇咬伤中毒的临床特点,总结其院前急救策略,为临床提供参考。方法选择2007—2012年在我科急诊抢救与住院的102例眼镜王蛇与银环蛇咬伤中毒患者,根据咬伤蛇类将患者分为眼镜王蛇组35例和银环蛇组67例,对比两组患者的院前急救措施、就诊时间、出现呼吸肌麻痹时间、伤情分级、临床表现、呼吸机治疗情况、预后情况及院外与院内死亡率等。结果两组患者的性别、年龄、院前急救措施及就诊时间比较,差异均无统计学意义(P>0.05)。眼镜王蛇组危重型患者所占比例高于银环蛇组(80.00%和58.21%,P=0.028)。两组患者均出现了全身症状,眼镜王蛇组局部肿痛发生率(8.57%和0,P=0.015)、多器官功能障碍综合征(MODS)发生率(20.00%和5.97%,P=0.030)高于银环蛇组,出现呼吸肌麻痹时间短于银环蛇组〔(3.8±2.2)h和(7.1±8.4)h,P=0.042〕。眼镜王蛇组治愈率低于银环蛇组(77.14%和95.52%),死亡率高于银环蛇组(22.86%和4.48%),且眼镜王蛇组院外死亡率高于银环蛇组(11.43%和1.49%,P=0.027)。结论相对于银环蛇,被眼镜王蛇咬伤患者病情更为凶险,出现呼吸肌麻痹的时间更短,MODS发生率及院外死亡率更高,医务工作者应充分认识呼吸机辅助呼吸治疗的关键性,加强神经毒类毒蛇咬伤院前急救策略的宣教。Objective To analyze the clinical features of poisoning from common nerve poison snake bites and summarize its pre-hospital care strategy in Guangxi province.Methods A total of 102 patients hospitalized due to bites from king cobra or bungarus multicinctus from 2007 to 2012 were divided into groups A（bitten by king cobra,n = 35）,B（bitten by bungarus multicinctus,n = 67）.Pre-hospital emergency measures,treatment time,time of respiratory muscle paralysis onset,injury classifications,clinical manifestations,ventilator treatment,prognoses,mortalities in or out of hospital were compared between 2 groups.Results There was no significant difference in gender,age,pre-hospital emergency measure,treatment time between 2 groups（P〈0.05）.The proportion of critically-ill patients was higher in group A than in group B（80.00% vs.58.21%,P = 0.028）.Both groups had systemic symptoms,but the incidences of local selling,multiple organ dysfunction syndrome（MODS） were higher in group A than in group B（8.57% vs.0,P = 0.015;20.00% vs.5.97%,P = 0.030）,and time of respiratory muscle paralysis onset shorter 〔（3.8 ± 2.2） h vs.（7.1 ± 8.4） h,P = 0.042〕,the curative rate lower（77.14% vs.95.52%）,mortality rate higher（22.86% vs.4.48%）,and out-of hospital death rate higher（11.43% vs.1.49%,P = 0.027）.Conclusion The patients who were bitten by king cobra have severer condition,shorter time of respiratory muscle paralysis onset,higher incidence of MODS and out-of-hospital death rate as compared with those who were bitten by bungarus multicinctus.Physicians should be fully aware of the importance of ventilator-assisted breathing therapy and strengthen the education about pre-hospital strategy for nerve poison snake bites.
