Analysis On Influencing Factors Of Survival Rate Of Replantation Of Severed Cut-fingers With Logistic Regression

Objective 1 Investigate on influencing factors of survival rate of replantation of severed cut-fingers.2 Patients in the control of gender , age, type of hand type,fingers, from broken plane, is completely preserved from the broken body of confounding factors and the means to explore the causes of finger injuries, the ratio of arteriovenous anastomosis. cut-fingers warm ischemia time and microsurgical replantation surgery skills on survival rate of replantation.Methods 1 A cluster sampling method, that is, lluazhong University of Sciencc and Technology, Lnion Hospital, longji Medical College, Hand Surgery and Division of Mcdical Rccords collected from December 2005 to December 2008 has done all of replantation of severed cut-fingers surgery patients,612 patients a total of 692 cut-fingers.2 Logistic regression model to explore wi th the patients gender, age, reason for finger injuries, the ratio of arteriovenous anast omosis, finger warm ischemia time, and surgery and so the relationship between survival rate and replantation of severed cut-fingers.Results 1 Tongji Medical College, Huazhong University of Hand Surgery and Division of Medical Records, Union Hospital,612 patients with a total of 692 of cut-fingers 616 that survived after replantation, necrosis of 76 means that the survival rate of 89%,11% necrosis rate.2 In the control patient's age, type of hand fingers, type finger amputation plane, finger amputation level and mode of preservation of severed fingers factors affecting the survival rate of replantation of severed cut-fingers factors:2.1 To tear off from the injury control group, cut off from the injury after digital replantation survival rate of wounded is a tear out of 36.14 times; mild compression of wounded after digital replantation survival rate is torn off from the injury of 15.31 times.2.2 To cut-fingers warm ischemic time greater than 12 hours for the control group, cut-fingers warm ischemic time 12 hours or less survival rate after replantation of severed cut-fingers warm ischemia time is more than 12 hours of 819.37 times.2.3 To refer to the ratio of 2:4 arteriovenous anastomosis as the control group, refers to the ratio of arteriovenous anastomosis 1-0 of digital replantation survival rate refers to the arteriovenous anastomosis for the 2:4 ratio of 0.0004 times (P=0<0.05); means the arteriovenous anastomosis of the ratio of 1:1 after digital replantation survival rate refers to the arteriovenous anastomosis 2:4 ratio of 0.0016 times (P=0<0.05); means moving venous ratio of 1:2 and the mean survival rate after replantation arteriovenous anastomosis ratio of 2:4 for digital replantation survival rate was not statistically significant (P=0.45>0.05); Research in this topics, because that arteriovenous anastomosis 2:1 and 2:2 ratio of complete necrosis after replantation, they refer to the ratio of arteriovenous anastomosis for replantation surgery survived 2:4 rates are not comparable.2.4 To junior resident in the control group, the total resident surgeon of digital replantation survival rate is junior resident of 18.47 times.Conclusion 1 Finger injury causes and inversely proportional to survival rate after replantation of severed cut-fingers.2 Amputated fingers warm ischemia time and replantation of severed cut-fingers, the survival rate after surgery was inversely proportional.3 The ratio of finger arterial and venous anastomosis and the survival rate of replantation of severed cut-fingers surgery were curve.1 Who amputated finger surgery micromanipulation level and survival rate after replantation of severed cut-fingers proportional.
