We present a case of unusually prolonged motor and sensory block for 30 hours after a successful single injection of ultrasound-guided interscalene block with 0.5% plain bupivacaine. All safety measures such as negative aspiration of blood injection at every 3 mL of drug with usual resistance, slow rate of injection and ultrasound documentation of spread of drug around C 5 and C 6 were followed. There was no evidence of neurological injury, but we should always be prepared to consider the possibility of nerve injury and take appropriate measures to prevent them.
