Continuous infraclavicular brachial plexus blockade: effect on survival of replanted digits

In replantation surgery, the use of continuous brachial plexus blockade (CBPB) is popular as it improves postoperative analgesia and vascular flow. The aim of our study was to determine whether CBPB may affect the odds of survivability of replanted digit(s). A four-year retrospective chart review was performed and various parameters affecting replant survival were examined. Outcome was recorded as successful if the transplanted digit(s) survived six months after discharge. All the independent variables were forced into a regression model without using a specific variable selection algorithm. The data for 146 patients was obtained from our chart review. The success rate of replanted digits in the patients reviewed was 65.8%. The logistic regression model showed a relation between the number of digits injured and replanted digit(s) survival. Our study showed that CBPB has no effect on the survivability of the replanted digit(s) till six months after hospital discharge.
