Cluster headache is an excruciating disorder with no cure. Greater occipital nerve blockades can transiently suppress attacks in approximately 50% of patients, however, its mechanism of action remains uncertain, and there are no reliable predictors of treatment response. To address this, we investigated the effect of occipital nerve blockade on regional cerebral blood flow (rCBF), an index of brain activity, and differences between treatment responders and non-responders. Finally, we compared baseline perfusion maps from patients to a matched group of healthy controls. ⋯ We provide new mechanistic insights regarding the aetiology of cluster headache, the mechanisms of action of occipital nerve blockades and potential predictors of treatment response. Future investigation should determine whether observed effects are reproducible and extend to other headache disorders.

Retroauricular or facelift approach for robotic thyroidectomy involves a long incision with extensive subcutaneous dissection causing severe pain and discomfort. Multimodal analgesic regimen with inclusion of intermediate cervical plexus block by anterior route provided excellent perioperative analgesia without affecting recurrent laryngeal nerve monitoring in 10 cases. ⋯ Median numeric pain rating scale score in 24 hours postoperatively was 3. None of the cases had any significant complications on follow-up.

Effects of continuous erector spinae plane block on postoperative pain in video-assisted thoracoscopic surgery: a randomized controlled study.
The aim of this prospective, randomized, controlled study was to evaluate the analgesic effect of ultrasonography (USG) guided continuous erector spinae plane block (ESPB) for postoperative analgesia in video-assisted thoracoscopic surgery (VATS). ⋯ This study shows that USG-guided continuous ESPB provides adequate analgesia following VATS as part of multimodal analgesia. Continuous ESPB significantly reduced opioid consumption and opioid-related side effects compared to those in the Control Group.
