ABSTRACT
Neuraxial opioid administration is one of the most common methods of anesthesia and analgesia,while itching is the most troublesome adverse effect.The current treatments for neuraxial opioid-induced pruritus still have certain limitations.This article reviews the current treatments and basic scientific findings(including neurotransmitters,opioid receptors,and signaling pathways)of pruritus caused by neuraxial opioids.Based on our recent findings on N-methyl-D-aspartate(NMDA)receptors and pruritus caused by neuraxial opioids,we provide new ideas for the treatment of itching caused by neuraxial opioids.Since NMDA receptors may play a key role in neuraxial opioid-induced pruritus,NMDA receptor antagonists can have certain therapeutic advantages.

Interfascial plane block is a quick,safe and simple technique that offers effective analgesia for video-assisted thoracotomy.However,the currently described methods still have certain limitations.We explored the application of a novel interfascial plane block method-iliocostal plane block in video-assisted thoracotomy,along with the use of stained cadaveric anatomy,with an attempt to shed new light on the analgesia for video-assisted thoracotomy.

Perioperative pulmonary aspiration is a serious complication during general anesthesia .For patients with un-known gastric condition , there is no effective method for the noninvasive evaluation of gastric content and volume preop-eratively.Because of the portable and real-time detection, bedside ultrasound can significantly reduce the risk of periop-erative reflux and pulmonary aspiration , which makes preoperative gastric contents visualized and accurate .
