Determining ED90 of Flumazenil for Selective Respiratory Distress Improvement Using Remimazolam During Endoscopic Submucosal Dissection of Gastric Neoplasms: A Prospective Study.

Background: Patients undergoing endoscopic submucosal dissection under monitored anesthesia care (MAC) with remimazolam may develop respiratory distress during the procedure. In these cases, low doses of flumazenil improved respiratory distress without completely reversing sedation, which is a novel phenomenon. This study aimed to explore the ED90 of flumazenil to selectively improve respiratory distress in patients with MAC treated with remimazolam.

[The three-dimensional reconstruction of penile suspensory ligament and adjacent structures based on the MRI image].

Objective: To establish a three-dimensional image of the penile suspensory ligament, and explore a stereoscopic and multi angle observation method of patient' s penile suspensory ligament.

Methods: This study selected the patients with small penis from our hospital as subjects. The participants were conducted on magnetic resonance imaging (MRI) examination before operation.
