Analysis of Influencing Factors of Early Necrosis of Affected Fingers after Replantation of Severed Fingers
Objective:To explore the influencing factors of early necrosis of affected finger after replantation of severed fingers.Method:The clinical data of 67 patients with replantation of severed fingers who admitted to Wudang Hospital Affiliated to Guizhou Medical University from January 2016 to December 2022 were retrospectively analyzed,all patients were treated with replantation of severed fingers,they were divided into the early necrosis group and the non-early necrosis group according to whether early necrosis occurred at 7 d after operation.The basic data of age,gender,smoking history,drinking history,diabetes mellitus,hypertension,fingering,preoperative ischemia time,vasospasm,injury type,postoperative infection,postoperative skin temperature and other aspects of two groups were collected,univariate analysis was performed first to obtain items with statistically significant differences,and then logistic regression analysis was performed to obtain the high-risk factors affecting early necrosis of the affected finger after replantation of severed fingers.Result:Among 67 patients,there were 13 cases of early necrosis after operation,and the early necrosis rate of the affected fingers was 19.40%(13/67).There were significant differences in smoking history,fingering,preoperative ischemia time,vasospasm,injury type,postoperative infection and postoperative skin temperature between two groups(P<0.05);there were no significant differences in age,gender,drinking history,diabetes mellitus and hypertension between two groups(P>0.05).Multivariate analysis showed that:smoking history(OR=7.255,95%CI:1.767,29.782),little finger(OR=7.040,95%CI:1.897,26.130),preoperative ischemia time≥8 h(OR=15.714,95%CI:3.095,79.798),vasospasm(OR=5.850,95%CI:1.563,21.894),crush injury of injury type(OR=5.667,95%CI:1.393,23.059),postoperative infection(OR=5.600,95%CI:1.544,20.312),postoperative skin temperature low temperature(OR=7.096,95%CI:1.872,26.906)were the high risk factors for early necrosis of the affected finger after replantation(OR>1,P<0.05).Conclusion:There is a certain risk of early necrosis of the affected finger after replantation of severed finger,which is closely related to smoking history,little finger,preoperative ischemia time≥8 h,vasospasm,crush injury of injury type,postoperative infection and postoperative skin temperature low temperature,early prevention and treatment are needed to avoid necrosis of affected limb.
