Virtual reality (VR), a technology that provides a stimulated sensory experience, has recently been implemented in various fields of medicine. Several studies have investigated the efficacy of VR on preoperative anxiety. The purpose of this meta-analysis was to validate whether VR could relieve preoperative anxiety in patients undergoing surgery. Electronic databases were searched to identify all randomized controlled trials (RCTs) investigating the effect of VR on preoperative anxiety. The prim

The purpose of this study was to compare the incidence of airway complications between extubation under deep anesthesia (deep extubation) and extubation when fully awake (awake extubation) in pediatric patients after general anesthesia. A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) statement standards. The review protocol was registered with the International Prospective Register of Systematic Reviews (registr

Ultrasound-guided erector spinae plane block (ESPB), a recent regional analgesic technique, has been used to manage acute pain after surgery. The aim of this meta-analysis is to identify the benefits of ESPB in patients undergoing laparoscopic cholecystectomy (LC). The authors searched PubMed, EMBASE, CENTRAL, CINAHL, and Web of Science to identify all randomized controlled trials (RCTs) evaluating the effects of ESPB on postoperative pain after LC. Primary outcome was defined as 24 h cumulative

High intraoperative inspired oxygen concentration is applied to prevent desaturation during induction and recovery of anesthesia. However, high oxygen concentration may lead to postoperative pulmonary complications. The purpose of this study is to compare the postoperative pulmonary parameters according to intraoperative inspired oxygen fraction in patients undergoing general anesthesia. We identified all randomized controlled trials investigating postoperative differences in arterial gas exchan

The use of lidocaine in spinal anesthesia may increase the risk of transient neurological symptoms (TNS) according to previous meta-analyses. However, the previous meta-analyses lacked data on some other local anesthetics and thus, more evaluations are still needed to compare the effect of lidocaine on the development of TNS. The objective of this study was to compare the risk of TNS according to lidocaine versus other local anesthetics in patients undergoing spinal anesthesia. A total of 39 ran

Urologic surgeries are widely performed, and the cases have increased owing to the fact that the elderly population is growing. The narrow and limited surgical space is a challenge in performing most urologic surgeries. Additionally, the elderly population is exposed to the risk of perioperative complications; therefore, a comprehensive understanding and approach are required to provide optimized anesthesia during surgery. We have searched the literature on anesthesia for urologic surgeries and

BACKGROUND: The role of intraoperative magnesium for the prevention of emergence agitation or delirium is unclear as there have been conflicting results reported by several randomized controlled trials. AIMS: The aim of this study was to investigate the effect of magnesium sulfate on emergence agitation or emergence delirium in pediatric patients. METHODS: Electronic databases, including PubMed, EMBASE, CENTRAL, CINAHL, Scopus, and Web of Science, were searched to identify studies which evaluate

Neurotoxic effects of local anesthetics (LAs) on developing motor neurons have not been documented. We investigated the neurotoxic effects of LAs on developing motor neurons in terms of cell viability, cytotoxicity, reactive oxygen species (ROS), and apoptosis. Embryonic spinal cord motor neurons were isolated from Sprague-Dawley rat fetuses and exposed to one of the three LAs-lidocaine, bupivacaine, or ropivacaine-at concentrations of 1, 10, 100, or 1000 µM. The exposure duration was set to 1 o
