Meta AnalysisSystematic Review and Meta-analysis of Virtual Reality in Pediatrics: Effects on Pain and Anxiety.
Medical procedures often evoke pain and anxiety in pediatric patients. Virtual reality (VR) is a relatively new intervention that can be used to provide distraction during, or to prepare patients for, medical procedures. This meta-analysis is the first to collate evidence on the effectiveness of VR on reducing pain and anxiety in pediatric patients undergoing medical procedures. ⋯ VR research in pediatrics has mainly focused on distraction. Large effect sizes indicate that VR is an effective distraction intervention to reduce pain and anxiety in pediatric patients undergoing a wide variety of medical procedures. However, further research on the effect of VR exposure as a preparation tool for medical procedures is needed because of the paucity of research into this field.

Pharmacological Characters of Oliceridine, a μ-Opioid Receptor G-Protein[FIGURE DASH]Biased Ligand in Mice.
A major advancement in the field of analgesic pharmacology has been the development of G-protein-biased opioid agonists that display less respiratory depression than conventional drugs. It is uncertain, however, whether these new drugs cause less tolerance, hyperalgesia, and other maladaptations when administered repeatedly. ⋯ Aside from reduced respiratory depression, G-protein-biased agonists such as oliceridine may reduce opioid maladaptations and enhance the quality of surgical recovery.

Narcolepsy, Anesthesia, and Sedation: A Survey of the Perioperative Experience of Patients With Narcolepsy.
Patients with narcolepsy may be at increased perioperative risk due to the interactions among anesthesia, narcolepsy, and narcolepsy medications. This study sought to determine the perioperative experience of narcoleptic patients undergoing anesthesia or sedation, the frequency of perioperative counseling, and self-reported surgical complications. ⋯ Most narcoleptic patients report not receiving counseling regarding potential worsening of narcolepsy symptoms postanesthesia or an increased risk of drowsy driving. Enhanced education of perioperative providers about potential narcolepsy-related issues is essential. Respondents frequently self-report adverse events in the perioperative period. Future studies should clarify the perioperative risk associated with narcolepsy to optimize the care and safety of narcoleptic patients.

Comparative StudyCulture-Negative and Culture-Positive Sepsis: A Comparison of Characteristics and Outcomes.
The primary objective of this study was to compare the characteristics of culture-positive and culture-negative status in septic patients. We also determined whether culture status is associated with mortality and whether unique variables are associated with mortality in culture-positive and culture-negative patients separately. ⋯ While culture status is important for tailoring antibiotics, culture-negative and culture-positive patients with sepsis demonstrate similar characteristics and, after adjusting for severity of illness, similar mortality. The most important factor associated with negative cultures is receipt of antibiotics during the preceding 48 hours. The risk of death in patients suspected of having an infection is most associated with severity of illness. This is aligned with the Sepsis-3 definition using Sequential Organ Failure Assessment score to better identify those suspected of infection at highest risk of a poor outcome.

Randomized Controlled Trial Comparative StudyComparison of Intermittent Intravenous Boluses of Phenylephrine and Norepinephrine to Prevent and Treat Spinal-Induced Hypotension in Cesarean Deliveries: Randomized Controlled Trial.
Phenylephrine (PE) is currently the vasopressor of choice to prevent and treat spinal-induced hypotension at cesarean delivery (CD). However, its use is often associated with reflex bradycardia. Norepinephrine (NE) has been put forward as an alternative vasopressor during CD due to its ability to treat hypotension while maintaining heart rate (HR). Recent studies have focused on the role of NE used as an infusion with favorable results compared to PE. No studies have compared equipotent bolus doses of PE and NE at CD. We hypothesized that when used in equipotent doses as an intermittent bolus regimen to prevent and treat spinal-induced hypotension, NE would result in a reduction in the incidence of bradycardia compared to PE. ⋯ When used as an intermittent bolus regimen to prevent and treat spinal-induced hypotension during CD, NE resulted in a significant reduction in the incidence of bradycardia as compared to an equipotent bolus regimen of PE. We conclude that the hemodynamic profile offered by NE during CD is superior to that of PE due to less fluctuations in HR and possibly cardiac output.
