Filter by:Sedatives and analgesics are usually given for analgesic, anxiolytic, or sedating purposes for patients with critical illness, while they inevitably inhibit respiratory and circulatory function. Sometimes, patients receive deep sedation to induce hypoventilation or suppress spontaneous respiratory effort. The sedation level in clinical practice is usually assessed with subjective sedation scoring systems, such as the Richmond Agitation Sedation Scale (RASS). However, studies have found that sedation depth based on RASS is not a reliable marker of respiratory drive during critical illness. In recent years, researchers have proposed to monitor the effects of sedatives and analgesics on respiratory indicators and to implement lung-protective sedation, such as P0.1, Pocc, Pmus, WOB, and PTP. However, different pharmacological characteristics, different depths of sedation, and different sedation regimens among different sedatives and analgesics make a great difference in their effects on respiration. Ciprofol is an analog of propofol, with increased stereoselective effects adding to its anesthetic properties, is increasingly used in the intensive care unit, but its effects on respiration are not well understood. Therefore, this study aims to investigate the effects of ciprofol on respiratory patterns, respiratory drive, and inspiratory effort in mechanically ventilated patients.
The aim of this study is to conduct a prospective, single-center randomized controlled study to investigate the effect of mild midazolam combined with sufentanil on radial artery cannulation in novice operators.
In this parallel, multicenter, single-blind randomized controlled trial, mechanical ventilated patients will be randomly assigned to two groups. One receives remimazolam to achieve sedation goals, while the other receives Midazolam. The primary outcome is the effect of remimazolam on duration of mechanical ventilated of critical patients compared to midazolam.
This study aims to evaluate the effectiveness of sedation and analgesia in the treament of colorectal polyps by colonoscopy.
The purpose of this study is to evaluate the anti-emetic effect of oral ondansetron. For this evaluation, the investigators will perform a multi-center, double-blind, placebo-controled, randomized study. The investigators assumption is that oral ondansetron prior to intramuscular ketamine will reduce the occurrence of ketamine-induced vomiting.
