Simultaneous determination of 11 related impurities in propofol by gas chroma…

A variety of related impurities, including starting materials, process impurities, and degradation products, can be detected in propofol. In this article, a sensitive and selective GC-MS/MS method using pulsed splitless injection technique for the determination of 11 main related impurities in propofol in one chromatogram is investigated. This method is extensively validated for its linearity, …

Recovery profile and side effects of remifentanil-based anaesthesia with desf…

Nitrous oxide (N2O) has been suggested to contribute to bowel distension, resulting in worsened operating conditions for laparoscopic surgery, and to increase incidence of postoperative nausea and vomiting. Therefore, our objective was to assess the feasibility of two remifentanil-based anaesthetic regimens free from N2O with special regard to recovery profile, postoperative analgesic demand an…

Changes in Concentrations of Free Propofol by Modification of the Solution

Because free propofol is thought to be responsible for pain on injection, we investigated the changes in concentrations of free propofol by modifying two kinds of propofol products in a medium- and long-chain triglyceride (MCT/LCT) emulsion and in an LCT emulsion. The techniques used in this study were 1) mixing 2% lidocaine (10:1), 2) mixing 5% dextrose in acetated Ringer’s solution to r…

Avoiding propofol injection pain in children: a prospective, randomized, doub…

Pain on injection limits the use of propofol in children. The combination of lidocaine and propofol is widely used to reduce pain. A new solvent [medium-chain triglyceride (mct)/long-chain triglyceride (lct)] has been advocated to be less painful than standard (lct) propofol in adults, but no information is available of its usefulness in pre-school children. We designed a prospective, randomiz…

Comparison of Sevoflurane versus Propofol under Auditory Evoked Potential Mon…

General anesthesia is used for most major surgeries, and the most common side effects include headache, nausea, vomiting, and sore throat. Major breast surgery is associated with a high incidence of postoperative nausea and vomiting (PONV). We compared the postoperative nausea and vomiting of propofol-based total intravenous anesthesia (TIVA) and sevoflurane (SEVO) anesthesia under auditory evo…

Propofol and survival: an updated meta-analysis of randomized clinical trials

Propofol is one of the most widely used hypnotic agents in the world. Nonetheless, propofol might have detrimental effects on clinically relevant outcomes, possibly due to inhibition of other interventions’ organ protective properties. We performed a systematic review and meta-analysis of randomized controlled trials to evaluate if propofol reduced survival compared to any other hypnotic agen…

Clinical trial: rebamipide promotes gastric ulcer healing by proton pump inhi…

Endoscopic submucosal dissection (ESD) is useful for treating gastric tumors. Several trials have shown the efficacy of 4 or 8 weeks of proton pump inhibitor (PPI) administration for post-ESD ulcers. However, if the size of the post-ESD ulcer is larger than predicted, PPI administration alone might not be sufficient for the ulcer to heal within 4 weeks. We examined the efficacy of a combination…

Anti-inflammatory Effects of Rebamipide According to Helicobacter pylori Stat…

The aim of the study was to investigate the effects of rebamipide on symptom, histology, endogenous prostaglandin, and mucosal oxygen free radicals in chronic erosive gastritis (CEG) patients by using sucralfate as a control. The trial also examined whether Helicobacter pylori infection would affect rebamipide-induced protection. A total of 453 endoscopy-confirmed CEG patients from 11 hos…
