Postoperative delirium has the potential to impact individuals of all age groups, with a significant emphasis on the elderly population. Its presence leads to an increase in surgical morbidity and mortality rates, as well as a notable prolongation of hospital stays. However, there is a lack of research regarding the prevalence, risk factors, and implications of postoperative delirium in developing nations like Ethiopia, which affects both patients and healthcare institutions.

Article Synopsis
  • Caudal blocks are a pediatric anesthesia technique used to manage pain after circumcision; this study aimed to compare the duration of the block when using a high-volume, low-concentration (HVLC) local anesthetic with and without the addition of clonidine.
  • The study included 129 children aged 0-3 years and measured the effectiveness of pain relief based on how long patients waited before needing additional acetaminophen; no significant differences were found between the clonidine and no-clonidine groups regarding pain management or emergence agitation.
  • Overall, the addition of clonidine did not significantly improve the outcomes of HVLC caudal blocks for children undergoing circumcision.

Background: Delirium in the post-anesthesia care unit (PACU) may be associated with worse outcomes in children with moyamoya disease (MMD). This retrospective study aimed to describe the prevalence of PACU delirium in children with MMD and investigate its risk factors.

Methods: Patients with MMD aged < 15 years who underwent indirect revascularization between January 2014 and October 2023 were included in this study.

Background: In an aging surgical patient population, preventing complications such as oversedation has taken increasing priority in perioperative care. Intraoperative use of virtual reality (VR) may decrease sedative requirements. We hypothesize that the use of immersive VR during total knee arthroplasty (TKA) will lead to decreased propofol requirements, improved patient-reported satisfaction, and reduced postoperative opioid requirements compared to active and usual care controls.
