Objective To explore the application effect of multidisciplinary integrated nursing path combined with high-quality nursing in operating room on patients with lower limb fracture and the effect on postoperative lower limb venous thrombosis．Methods From January 2021 to October 2022,70 patients with lower limb fracture admitted to our hospital were randomly divided into combination group and conventional group,with 35 cases in each group．Patients in the conventional group received routine nursing,and patients in the combined group received multidisciplinary integrated nursing path combined with high-quality nursing in the operating room．The nursing effect of the two groups was compared．Results The first time of getting out of bed in the combined group was earlier and postoperative VAS score was lower than those in the conventional group（P<0.05）,and the length of hospital stay and drainage tube removal time were not significantly different between the two groups（P>0.05）．After nursing intervention,the prothrombin time（PT）and activated partial thromboplastin time（APTT）of the two groups were prolonged,and the plasma fibrinogen（FIB）decreased,and the change range of the combined group was greater（P<0.05）．The incidence of venous thrombosis in the combined group was significantly lower than that in the conventional group（0.00% vs 17.14%,P<0.05）．The nursing satisfaction of patients in combination group was higher（P<0.05）．The activities of daily living score and Fugl-Meyer score of both groups increased one month after surgery,and the combined group was higher than the conventional group（P<0.05）．Conclusions Multidisciplinary integrated nursing path combined with high-quality nursing in operating room can improve perioperative indicators and blood hypercoagulability of patients with lower limb fractures,reduce the incidence of lower limb venous thrombosis,improve nursing satisfaction,long-term daily living ability and limb motor function of patients．
