Meta AnalysisAnalgesic Effects of Regional Analgesic Techniques in Pediatric Inguinal Surgeries: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.
Various regional analgesic techniques have been used in pediatric inguinal surgery to facilitate postoperative recovery. However, each technique's relative performance was undetermined owing to the lack of quantitative analysis. ⋯ The quadratus lumborum and transversus abdominis plane blocks had the longest time to the first rescue analgesic and the least rescue analgesic requirement for pediatric inguinal surgeries. Specifically, the quadratus lumborum block had the longest analgesic duration in inguinal hernia repair, and the caudal block was found to be the only regional analgesia that extended the time to the first rescue analgesic in pediatric orchidopexy. Most included randomized controlled trials had some concern or a high risk of bias, and future studies should focus on providing high-quality evidence to further clarify the analgesic effects of regional analgesia for pediatric inguinal surgeries.

ReviewThe Role of Remimazolam in Neurosurgery and in Patients With Neurological Diseases: A Narrative Review.
Remimazolam is a novel ultrashort-acting benzodiazepine that produces sedation by acting as a positive allosteric modulator of the gamma-amino butyric acid-A receptor. Its high water solubility and metabolism via tissue esterases allow for a rapid onset of sedation/anesthesia and prompt arousal despite prolonged use. In addition, the effects of remimazolam can be reversed with flumazenil. ⋯ Considerations for remimazolam use in patients with neurological diseases are also highlighted. In addition, the impact of remimazolam on postoperative excitation, risk for postoperative delirium, and delayed neurocognitive recovery are discussed. Although there seems to be a clinical promise for remimazolam based on limited case studies and our own institutional experience of its use, further clinical investigation is warranted to understand the potential impact of remimazolam on surgical and neurological outcomes.

Observational StudyPrevalence and Predictors of Preoperative Anxiety in Patients With An Intracranial Supratentorial Neoplasm Undergoing Surgery.
Preoperative anxiety is common among patients, particularly in neurosurgical patients. The aim of the study was to evaluate the incidence and predictive factors of preoperative anxiety using the state anxiety scale of the State-Trait Anxiety Inventory (STAI-S) among patients undergoing elective craniotomy for a supratentorial neoplasm. This study also determined the optimal Amsterdam Preoperative Anxiety and Information Scale (APAIS) score for the identification of preoperative anxiety in this cohort. ⋯ Patients with supratentorial neoplasms have a high incidence of preoperative anxiety; an APAIS score of 10 is the optimal cutoff to identify anxious patients in the preoperative period. Need-for-information about surgery and right-sided tumor laterality are independent predictors of preoperative anxiety.

Randomized Controlled Trial
Delayed vs. Early Laparoscopic Appendectomy (DELAY) for Adult Patients with Acute Appendicitis: A randomized controlled trial.
To assess whether delaying appendectomy until the following morning is non-inferior to immediate surgery in those with acute appendicitis presenting at night. ⋯ The DELAY study is the first trial to assess delaying appendectomy in those with acute appendicitis. We demonstrate the noninferiority of delaying surgery until the after morning.
