Comparative Assessment of a Special Protective and Moistening Bandages for Eventrated Abdominal Organs in Experiment
Abdominal organs eventration refers to absolute findings of penetrating injury of the abdomen, its rate reaching 35% in the given casualty category. Complete eventration is always complicated by abdominal cavity infection contamination that can result in serious consequences, such as intestinal obstruction, postoperative peritonitis, which in the case of its persistence for 20 min or more, can inevitably cause adhesions development. At present, there are no ready-to-use multipurpose aseptic impregnated bandages including those to protect eventrated abdominal organs, in the enclosures of complete-authorised equipment of the Medical Corps, the Armed Forces of the Russian Federation. A series of long-term experiments dealing with the use of traditional and experimental bandages to protect and moisten eventrated small intestine loops was carried out. 45 laboratory rodents were subdivided into 6 groups: 2 control groups using traditional covering methods and 4 experimental groups using ready-to-use samples. 4 h, 2 and 7 days after bandaging the bandage efficiency was assessed with respect to visual and laboratory criteria (bandage adhesion, presence of peritonitis and adhesions, complete blood count findings). It was shown that in the case of traditional bandages the animals from the group using saline solution developed peritonitis and adhesions in 50% of cases whereas in the group using petrolatum - in 14 and 57% of cases respectively. Proposed ready-to-use bandages demonstrated better protection: there was no peritonitis in all the experimental groups, and only 25% of animals developed adhesions. The lowest rate of complications was noted when «spunlace» bandages without impregnation and «spunbond» bandages impregnated with vinyl+silicone were used. The results of the conducted experimental study evidence the need to revise and improve traditional protective and moistening techniques for eventrated abdominal organs (gauze bandage impregnated with saline or petrolatum) presently used. At present, by an order of the Ministry of Defence of the Russian Federation, experimental samples of special aseptic bandages made of nonwoven textile material impregnated with vinyl-silicone gel and chlorhexidine are being developed. These samples after being improved and tested could be recommended for addition to the enclosures of complete-authorised equipment and supply registration of the Medical Corps, the Armed Forces of the Russian Federation.
