Randomized Controlled Trial
Greater occipital and supraorbital nerve blockade for the preventive treatment of migraine: a single-blind, randomized, placebo-controlled study.
Nerve injections have been used for the acute and preventive treatment of migraine in recent decades. Most of these injections focused on greater occipital nerve (GON) blockade. However, few studies were placebo controlled, and only a few of them investigated GON and supraorbital nerve (SON) blockade together. This study aimed to evaluate the efficacy of GON and SON blockade with local anesthetics for the preventive treatment of migraine without aura. ⋯ The results suggest that GON and SON blockade with lidocaine was more effective than the placebo in the prophylactic treatment of both episodic and chronic migraine.

Thoracotomy is one of the most painful surgeries; therefore, video-assisted thoracoscopic surgery (VATS) was developed to reduce the surgical stress of thoracotomy. Although VATS results in reduced postoperative pain compared with thoracotomy, it is still painful. Serratus plane block (SPB) is a novel technique that provides lateral chest wall analgesia by blocking the lateral branch of the intercostal nerve. ⋯ Ultrasound-guided SPB could be a safe and effective regional anesthesia technique for VATS.

Impact of Ultrasound-Guided Transversus Abdominis Plane Block on Postoperative Pain and Early Outcome After Laparoscopic Bariatric Surgery: a Randomized Double-Blinded Controlled Trial.
Based on the promising results of transversus abdominis plane (TAP) block in various abdominal procedures, this study aimed to investigate its effect on postoperative pain and early outcome after laparoscopic bariatric procedures. ⋯ Using US-guided TAP block in adjunct with laparoscopic bariatric surgery managed to achieve lower pain scores, lower opioid requirements, lower PONV scores, earlier ambulation, shorter time to pass flatus, and comparable hospital stay and complication rate to the control group.

This study modeled image-guided epidural drug delivery to test whether intraprocedural distribution of pre-injected contrast reliably predicts the neuroanatomical reach of resiniferatoxin-mediated nociceptive neurolysis. ⋯ Periganglionic resiniferatoxin/Tween80 induced bilateral ablation of spinal cord substance P despite exclusively unilateral targeting. These data suggest that the location of pre-injected contrast is an imperfect surrogate for the neuroanatomical range of drugs delivered to the dorsal epidural compartment that may fail to predict contralateral drug effects.
