ABSTRACT
Objective To find out the causes of the failure of the replanted finger and to increase the survival rate of replantation.Methods The trauma,operation condition and nursing care after operation of the 24 failure cas- es of 31 replantation of severed fingers that have been treated in this hospital from January 1999 to December 2006 were retrospectively analyzed.Results Of the 31 necrotic fingers,there were 21 necrotic fingers caused by untimely treatment of vascular articulo,7 by infection,1 by smoking and 2 by uncooperative treatment because of out-of-bed activity.There were 9 replantation of fingers loss of blood supply in one day,12 fingers from one day to three days, 8 fingers from four days to seven days,2 fingers more than nine days.Conclusion The operation indication should be strictly mastered.There should be a complete debridement and haemostasis during the operation,the quality of vascular anastomose should be improved and the pressure of the anastomosing vascular should be avoided.Strict ob- servation after operation,intensive nursing and timely treatment of vascular articulo are the key factors for improving the survival rate of replantation of severed finger.
