Abstract: The nursing experience of repair and reconstruction for severely mangled legs in 32 patients was reported. In view of the risk of acute renal failure after severe trauma,the possibility of vascular crisis after vascular and skin flap transplantation,and the failure of negative pressure closure drainage of wound,infection of external bone fixation needle tract and cross infection of multiple drug-resistant bacteria,the monitoring of renal function should be strengthened after operation,and we combined with percutaneous oxygen saturation monitoring to judge the blood circulation of the affected limb,and grasped the observation method and opportunity of skin flap. The needle care program was implemented in stages and the patients infected with multi-drug-resistant bacteria were seperated into different rooms or treated independently. All the 32 cases got successful limb salvage,the average hospital stay was 21 days. They were followed up for more than 1 year,25 cases had satisfactory functional evaluation,5 cases had basic functional recovery,2 cases retained the function of the affected limb to the maximum extent and had walking lameness with pain.
