Background and Aims:

Peripheral nerve blocks (PNB) are an integral part of todays anesthetic management,worldwide. Although residual neurological deficits after a peripheral nerve block, subsides within 24 hours of postoperative period,sometimes it extends beyond 48 hours. We want to find the incidence of patients who continue to experience postoperative neurologic deficits 48 hours after a PNB and assess if we are in accordance with the incidence found internationally (3.7% - 8.2%). We also want to identify possible causes which could have resulted in these neurologic deficits.


Aftter obtaining approval from Dubai health Authority,we identified total number of patients receiving PNBs in year 2014,2015,2016 by retrospectively searching our database. Then we identified the number of patients who experienced neurologic deficits extending beyond 48 hours after a PNB. To identify a cause, we have so far analysed 50 out of a total of 92 of these patients with respect to their diagnosis, surgical details, anesthetic details, neurologic deficit experienced,investigations and results,followups.


 Incidence for a combined 3 years period (2014-2016) was found to be 1.25% .Out of 50 patients that we analysed so far,10 patients experienced neurologic deficits extending beyond 48 hours due to anesthetic causes,6 due to surgical reasons,a combined 8 due to nature of injuries itself.In rest 26 patients no obvious cause could be identified.


A careful selection of patients who will receive peripheral nerve blocks, a higher emphasis on block technique and right concentration and volume planned for each patient, can further reduce the anesthetic related neurologic deficits extending beyond 48 hours.
