Abstract:
Objective To explore effects of marine environment on the treatment of severe sea - battle casualties so as to improve medical care of casualties at sea. Methods Sixty mongrel dogs were randomly divided into 3 groups: the dock group, sea group 1 (scale of wind force 2～4, waves 2～3 m, rolling and pitching of the ship with 5°～10°) and sea group 2 ( scale of wind force 5～7, waves 3～5 m, rolling and pitching of the ship with 11°～25°), each group consisting of 20 dogs. For sea group 1 and 2, experiments were made while the hospital ship was underway. And for the dock group, researches were made in the laboratory at the dock side of the same sea region. The animals were subjected to craniocerebral firearm injury,open chest injury, open abdominal injury, pelvic limb injury, bum injury, and then were treated with seawater immersion. The dogs were thereafter given surgical operation and routine treatment. A total of 20 operations were performed in each group, including craniotomy, thoracotomy, ventrotomy, lower limb fracture internal fixation, arteriorrhaphy, tracheotomy, venesection and debridement. Surgery time, quality and mortality of the animals 3 days after injury were compared between the 3 groups. Results Two hundred and eighty operations were performed in each group, in different surgery time, with the dock group totaling 300.6 minutes, sea group 1 and 2 totaling 369.9 and 426.3 minutes respectively. The surgery time of sea group 1 was longer by 22.9%than the dock group (P ＜0. 01 ＝, and the surgery time of sea group 2 was longer by 15.4% than that of sea group 1 (P＜0. 01 ＝. Following arteriorrhaphy, obstruction of 1 vessel was noted in the dock group, while obstruction of 3 and 5 vessels were seen in sea group 1 and 2. Mortality of the animals in the dock group was 35% (7/20) in 3 days, while that of the animals in sea group 1 and 2 was 45% (9/20) and 55% (11/20)respectively. Mortality of the animals in sea group 2 was apparently the highest ( P＜0. 01＝. Conclusions Marine environment had obvious effects on surgery time, quality and mortality of animals. Understanding of the surgery features at sea, improvement of shipboard surgical skills of medical personnel and acclimatization of marine environment are the key to the shortening of surgery time, improvement of surgical quality and reduction of mortality.
