Unusually prolonged motor and sensory block following single injection ultrasound-guided infraclavicular block with bupivacaine and dexamethasone.

We present a case of unexpectedly prolonged motor and sensory block following a successful single injection ultrasound - guided infraclavicular block with bupivacaine (0.25%) and dexamethasone (8 mg). ultrasound guidance and safety measurement such as injection of the local anaesthetic at a slow rate and verifying that usual resistance was felt throughout the injection, has been applied.
