Perineural and intravenous dexmedetomidine as a local anaesthetic adjunct has not been compared previously in fascia iliaca compartment block (FICB). The aim of this study was to compare the efficacy and side effect profile of dexmedetomidine as an adjunct to bupivacaine in single dose FICB for femur surgeries in two different routes i.e., perineural and intravenous route. ⋯ Perineural dexmedetomidine effectively prolongs the USG guided FICB analgesic duration and reduces the 24 h postoperative morphine consumption when compared to intravenous dexmedetomidine as a local anaesthetic adjuvant for femur surgeries.

Ultrasound (USG)-guided injection in pterygopalatine fossa is an indirect approach to block the trigeminal nerve. Trigeminal nerve block for maxillofacial surgeries may provide preemptive analgesia, reduce opioid consumption and opioid-related adverse effects. ⋯ USG-guided TNB reduces perioperative opioid consumption in patients undergoing faciomaxillary surgery with better patient pain scores.
