| 目的:观察多功能自控加压止血绷带对犬股动脉出血的止血效果，探讨其控制动脉出血的有效性和安全性，为临床应用奠定基础。方法:采用橡皮带止血带、卡式止血带和多功能自控加压止血绷带（简称止血绷带）3种止血带对18只犬进行股动脉止血。分别在止血后0.5、1、3、6 h检测3组动物的止血带下压力、相关生理生化指标，观察受累组织病理损伤程度。结果:3种止血带止血效果确切，均达到动脉切口无出血。止血绷带组的带下压力小于其他两组（P<0.05）。止血后各时间点，止血绷带组犬血清生化指标（CK、K+）和皮温（T）变化小于橡皮管组、卡式止血带组（P<0.05）；止血绷带组静脉血气指标PvO2、SvO2高于卡式止血带组、橡皮管组（P<0.05），PvCO2低于卡式止血带、橡皮管组（P<0.05）。束扎6 h后病理分析显示，止血绷带组肌肉组织损伤小于其他两组。结论:止血绷带对犬股动脉出血的止血效果与橡皮带及卡式止血带相当，且对组织损伤更小。 |

| Abstract: |
| Objective:To observe the efficacy and safety of the multi-functional self-controlled pressure hemostatic bandage(MSPHB) in treatment of canine femoral artery bleeding,so as to lay a foundation for clinical application.Methods:Rubber tubing,half-hitch tourniquet and our MSPHB were used to treat 18 anesthetized mongrel dogs with fatal femoral artery injury. The pressure under the tourniquet and the related physiopathological parameters were measured 0.5,1,3,and 6 h after tourniquet application. The injuries of the involved tissues were observed.Results:The 3 treatments all had prominent hemostasis effect and the arterial incisions had no bleeding after treatment in all groups. The pressure produced by MSPHB was significantly lower than those by the other two tourniquets (P<0.05). The changes of serum CK,K+ and skin temperature in MSPHB group were significantly smaller than those of the other 2 groups at all defined time points (P<0.05). Also,PvO2 and SvO2 in the MSPHB group were significantly higher than those of the other 2 groups (P<0.05),but the PvCO2 was significantly lower than those in the other 2 groups(P<0.05).The injury of the muscle in the MSPHB group was slighter than those of the other 2 groups 6 h after application of tourniquets. Conclusion:MSPHB has similar hemostasis effect to rubber tubing and half-hitch tourniquet,and it also has less injury to the involved tissues. |
