Weakness of contralateral upper limb after interscalene block - A case report.

We have reported a case of right upper limb injury of shoulder and elbow who was managed with ultrasound-guided interscalene block during surgery and indwelling catheter for postoperative analgesia. He developed weakness in the contralateral upper limb in the postoperative period due to inadvertent spread of local anaesthetic in the cervical epidural space. No serious complication occurred due to timely intervention.

Comparative evaluation of monopolar and bipolar radiofrequency ablation of genicular nerves in chronic knee pain due to osteoarthritis.

Background And Aims: Monopolar radiofrequency ablation (MRFA) of the genicular nerve is effective in managing chronic knee pain from osteoarthritis (OA); however, the procedure itself is associated with significant pain due to manipulation of electrode to localise tiny genicular nerves. We hypothesised that inserting two electrodes to target the genicular nerves [bipolar radiofrequency ablation (BRFA)] without sensory localisation can decrease the procedural pain with equal analgesic efficacy in treating knee pain.

Methods: Thirty patients with chronic knee pain due to OA were randomised to receive either MRFA ( = 15) or BRFA ( = 15), after having 50% pain relief with diagnostic genicular nerve block.

Fluoroscopic-guided erector spinae plane block: A feasible option.

Erector spinae plane block (ESPB) is a new truncal block which has been used successfully to manage many acute and painful conditions including multiple fractured ribs. This block is primarily an ultrasound-guided block. We have evaluated the feasibility of fluoroscopic guidance for this block.
