Determination of the ED of intranasal sufentanil combined with intranasal dexmedetomidine for moderate sedation during endoscopic ultrasonography.

Background: Sedation during endoscopic ultrasonography (EUS) poses many challenges and moderate-to-deep sedation are often required. The conventional method to preform moderate-to-deep sedation is generally intravenous benzodiazepine alone or in combination with opioids. However, this combination has some limitations.

Commentary on "Multi-Component Care Bundle in Geriatric Fracture Hip for Reducing Postoperative Delirium".

The letter to the editor suggested several questions regarding the methodology of the recent article by Lam et al who determined effect of multicomponent care bundle on the development of postoperative delirium. This article is published in Geriatric Orthopaedic Surgery & Rehabilitation  2021; 12:21514593211004530. Our concerns included the incomplete preoperative assessment, possible influences of anaesthetic and intraoperative managements on the development of postoperative delirium, bias effect of postoperative analgesia on the primary and secondary findings, and real clinical value of multicomponent care bundle to decrease the risk of postoperative delirium.

Prospective, randomized comparison of two supplemental oxygen methods during gastroscopy with propofol mono-sedation in obese patients.

Background: Hypoxemia is a common complication in obese patients during gastroscopy with sedation. The Wei nasal jet tube (WNJT) is a new special nasopharyngeal airway with the ability to provide supraglottic jet ventilation and oxygen insufflation its built-in wall channels. The aim of this study was to compare the efficacy and safety of the WNJT a nasal cannula for supplemental oxygen during gastroscopy with propofol mono-sedation in obese patients.

Comparison of two supplemental oxygen methods during gastroscopy with propofol mono-sedation in patients with a normal body mass index.

Background: Hypoxemia due to respiratory depression and airway obstruction during upper gastrointestinal endoscopy with sedation is a common concern. The Wei nasal jet tube (WNJT) is a new nasopharyngeal airway with the ability to provide supraglottic jet ventilation and oxygen insufflation its built-in wall channel. The available evidence indicates that with a low oxygen flow, compared with nasal cannula, the WNJT does not decrease the occurrence of hypoxemia during upper gastrointestinal endoscopy with propofol sedation.
