Application of tourniquet in amputation for lower limb gangrene
Objective To explore the efficacy and safety of using a tourniquet in amputation for lower limb gangrene.Methods All patients underwent amputation for lower limb gangrene from January,2009 to June,2023 in Beijing Bo'ai Hospital were reviewed,involving 41 patients with a total of 44 limbs,and they were divided into non-tourniquet group(n=28)and tourniquet group(n=16)according to whether a tourniquet was used during surgery.The am-putation field clearness,surgical bleeding,incision healing,reoperation rate within 30 days post-operation,intra-operative blood pressure and heart rate,and operation time were compared.Results The amputation field was clearer in the tourniquet group(χ2=42.385,P<0.001),with less bleeding(Z=-2.082,P<0.05).No tourniquet-related local damages,such as nerve damage and skin injuries,was observed in the limbs using tourniquets.The incidence of grade A of incision healing was not significantly different(χ2=0.028,P=0.624).Conclusion Application of tourniquet can improve the amputation field clearness and reduce bleeding during amputation for lower limb gangrene,without affecting incision healing.
