【摘要】：目的　探讨不同复温方式对犬腹部开放伤合并海水浸泡救治时血流动力学的影响。方法　成年杂种犬 30只制作成腹部开放伤动物模型 ,伤后均浸泡人工海水中 ,2h后打捞出水 ,随机分为 3组。自然复温组 (n=10 ) :将动物移至温暖环境 ,靠机体自身产热自发复温 ;体表复温组 (n=10 ) :用电热毯体表加温 ;体中心复温组 (n=10 ) :1/3张盐水 4 2℃水浴 2 0min后 ,腹腔用 1/2张盐水持续灌洗 2h。观察不同复温方式对犬腹部开放伤合并海水浸泡救治时体温、心率、平均动脉压、中心静脉压和心输出量的影响。结果　自然复温组复温效果不满意 ,救治 6h后体温 34 8℃ ,未恢复正常体温 ,血压提升困难、心动过速、心输出量降低。体表复温组复温效果优于前组 ,6h后体温 36 9℃ ,接近致伤前体温 ,但血压、心率和心输出量也出现同前组类似的表现 ,只是程度较轻。体中心复温组复温效果满意 ,救治后 4h体温、平均动脉压、中心静脉压和心输出量基本恢复正常。结论　腹部开放伤海水浸泡后体温过低的救治时最好采用体中心复温方式。
[Abstract]:Objective to investigate the effects of different rewarming methods on hemodynamics of dogs with open abdominal injury and seawater immersion. Methods Thirty adult mongrel dogs were made into an open abdominal injury animal model. All the dogs were soaked in artificial seawater for 2 hours after injury, and were randomly divided into 3 groups. Natural rewarming group (NN10): the animals were moved to a warm environment and spontaneously reheated by the body's own heat production; the body surface rewarming group (NN10) was heated with an electric blanket; the body center rewarming group (n / 10) was treated with 1 / 3 brine at 42 鈩，
