PEROPERATIVE MEDIAN NERVE BLUSHING, A PREDICTOR OF ADEQUATE DECOMPRESSION!

Abstract

INTRODUCTION: Median Nerve has small vessel on the volar aspect of the nerve which is filled with blood and results in so called ‘ BLUSHING’ of the nerve once it has been decompressed. It was thought that the nerve which didnot blush meant an inadequate decompression was carried out.

PURPOSE: To evaluate whether ‘Blushing’ of the Median Nerve is correlated with adequate decompression and level of recovery in Carpal Tunnel Syndrome through Mini Palmar Incision.

METHODS & MATERIALS: Retrospective analysis of a Single Surgeon practise where it was documented in operation notes whether the nerve was seen to ‘Blushed’ at the time of surgery.They were assessed postoperatively from notes for complete resolution of symptoms and whether there was any recurrence of symptoms.

RESULTS: n=330 Carpal Tunnel Decompressions were reviewed. It was noted that those who had complete resolution of symptoms had ‘Blushing’ noted at the time of surgery compared to those who had partial or incomplete resolution of symptoms wher ‘No BUSHING’ was noticed. Average time of follow up = 6 weeks. Blushing Noted at the time of decompression 192, Recovery/ improvement of symptoms 189, Blushing not noted at the time of surgery 38, NO documentation about Blushing in 100

CONCLUSION: Blushing of Median Nerve intraoperatively is a reliable sign for complete decompression of the nerve and is correalted with good final outcome.
