Dexmedetomidine Nasal Spray on Emergence Agitation After Ear, Nose, and Throat Surgery: Protocol for a Randomized, Double-Blind, Controlled Trial.

Background: Emergence agitation (EA) is a state of psychomotor hyperactivity following general anesthesia and is associated with postoperative complications. Patients undergoing ear, nose, and throat (ENT) surgery are at a high risk for EA. We aim to assess whether preoperative dexmedetomidine nasal spray reduces the occurrence of EA for patients undergoing ENT surgery.

Use of dexmedetomidine during light versus deep anaesthesia on postoperative delirium among elderly patients undergoing major non-cardiac surgery: protocol for a multicentre randomised factorial trial.

Introduction: Elderly patients are at a high risk of postoperative delirium (POD), leading to increased postoperative morbidity and mortality. The use of dexmedetomidine and depth of anaesthesia may influence POD. This study aims to determine the effects of dexmedetomidine infusion versus normal saline placebo during light versus deep anaesthesia on POD among elderly patients undergoing major non-cardiac surgery.

Intravenous Lidocaine Compared with Quadratus Lumborum Block on Postoperative Analgesia Following Laparoscopic Renal Surgery: Protocol for a Randomized Noninferiority Trial.

Background: Patients undergoing laparoscopic renal surgery often experience significant postoperative pain. Quadratus lumborum block (QLB) provides effective postoperative pain control after laparoscopic procedures, while lidocaine administered intravenously also exerts analgesic effects for surgical patients. We design this trial to compare the effects of i.

Oxycodone vs. sufentanil combined with quadratus lumborum block vs. transverse abdominis plane block in laparoscopic major gastrointestinal surgery: A randomized factorial trial protocol.

Background: Multimodal analgesia plays a key role in enhanced recovery after surgery. Herein, we describe a trial protocol investigating the effects of oxycodone-vs. sufentanil-based patient-controlled analgesia in combination with quadratus lumborum block (QLB) vs.

Intraoperative dexmedetomidine on postoperative sleep disturbance in older patients undergoing major abdominal surgery: A randomized controlled trial protocol.

Background: Postoperative sleep disturbance (PSD) occurs frequently in patients who undergo major abdominal surgical procedures. Dexmedetomidine is a promising agent to improve the quality of sleep for surgical patients. We designed this trial to investigate the effects of two different doses of intraoperative dexmedetomidine on the occurrence of PSD in elderly patients who have major abdominal surgery.
