Objective To study the impacl of ship vacillation under different sea conditions on the ihoracic and abdominal operations, and Lo help evaluate the rescuing ability of medical ship during war. Methods We selecled splenectomy and closed thoracic drainage as representative operalions by the Delphi melhod. Tolally 20 mongrel dogs were randomly divided into group A (the continental group, n = 5 ) , group B (the second level sea conditions group, n = 5 ) , group C (the fifth level sea condilions group, n = 5 ) and group D ( the eiqhlh- level sea conditions group, n = 5 ). The operalion time, reactions of surgeons and nurses, and factors affecling the operalion were recorded. Results The operations were accomplished smoolhly in every group,and there was no significant difference among 4 groups having closed thoracic drainage ( P＞ 0. 05 ). But when having spleneclomy, significant differences were showed belween group D and group A (P＜0. 01) , group B and group C ( P ＜0. 05 ). However, there was no significant difference among group A,B and C (P ＞0. 05 ). Conclusion Simple operation can be accomplished smoolhly in medical ship under the eighlh - level sea conditions, otherwise it will be more difficult to accomplish complicated operation with the increasing of swing angle.%目的 通过对在陆地和不同摇摆度模拟器内开展脾切除术和胸腔闭式引流术进行对比研究,初步了解不同海况下卫生船舶内完成胸腹部手术情况及完成手术用时变化,为评估卫生船舶战时救治能力提供参考.方法 通过Delphi法,咨询全军野战外科专业15名专家,通过3轮咨询,筛选出脾切除术和胸腔闭式引流术做为胸腹部急救手术的代表术式.20只成年杂种犬随机分成A组(陆基组)、B组(2级海况组)、C组(5级海况组)、D组(8级海况组),每组5只,行脾切除术和胸腔闭式引流术,记录手术完成情况及所用时间(s),同时记录实验过程中手术人员反应和影响手术完成的因素.结果 4组手术均顺利完成,B、C组完成脾切除术用时与A组无统计学差异(P>0.05),D组完成脾切除术用时与B、C组有统计学差异(P<0.05),与A组比较有非常显著差异(P<0.01).而各组行胸腔闭式引流术所用时间均无统计学差异(P>0.05).实验过程中,手术人员轻度头晕,但对完成手术操作无明显影响.结论 卫生船舶在8级以下海况条件,手术人员可顺利完成胸腹部急救手术,当摇摆幅度较大时,完成复杂手术难度及手术用时相应增加,而对简单操作影响不大.
