Meta AnalysisWhich 5-HT3 antagonist prevents nausea and vomiting in cesarean section more effectively: a network meta-analysis.
Selective 5-hydroxytryptamine 3 receptor (5-HT3) antagonists are commonly used to prevent nausea and vomiting (NV) after cesarean section, but the comparative efficacy of different 5-HT3 antagonists remains unclear. This network meta-analysis aimed to determine which 5-HT3 antagonists might be the preferred choice for preventing NV in parturient scheduled for elective cesarean delivery under spinal anesthesia. ⋯ Based on available data, ondansetron 12 mg may have the best efficacy in preventing PONV, PON, and POV. Additionally, more studies are warranted to compare the safety of ondansetron 12 mg versus granisetron two mg.

ReviewRecruitment-to-inflation ratio for bedside PEEP selection in acute respiratory distress syndrome.
In acute respiratory distress syndrome, the role of positive end-expiratory pressure (PEEP) to prevent ventilator-induced lung injury is controversial. Randomized trials comparing higher versus lower PEEP strategies failed to demonstrate a clinical benefit. This may depend on the inter-individually variable potential for lung recruitment (i.e. recruitability), which would warrant PEEP individualization to balance alveolar recruitment and the unavoidable baby lung overinflation produced by high pressure. ⋯ In case of intermediate R/I (≈0.5), a more granular assessment of recruitability may be needed. This could be accomplished with advanced monitoring tools, like sequential lung volume measurement with granular R/I assessment or electrical impedance tomography monitoring during a decremental PEEP trial. In this review, we discuss R/I rationale, applications and limits, providing insights on its clinical use for PEEP selection in moderate-to-severe acute respiratory distress syndrome.

Remimazolam for anesthesia and sedation in cardiac surgery and for cardiac patients undergoing non-cardiac surgery: a systematic-narrative hybrid review.
Remimazolam, an ultra-short-acting benzodiazepine recognized and approved as an anesthetic and sedative in multiple countries, offers a distinctive pharmacokinetic profile, boasting advantages such as rapid onset, short action duration, and rapid recovery. These attributes may contribute to enhanced hemodynamic stability and a diminished risk of respiratory depression compared to other sedatives. ⋯ Though remimazolam has demonstrated potential safety, efficacy, and ease-of-use for both anesthesia induction and maintenance in cardiac surgery patients and high-risk cardiovascular patients undergoing non-cardiac surgery, further research is imperative to delve into specific patient subgroups (e.g., the elderly or emergent procedures) so as to ascertain optimal dose ranges to suit diverse clinical scenarios.

Observational StudyIncidence of emergence delirium after homeostasis-guided pediatric anesthesia for ear-nose-throat surgery.
Emergence delirium is a complication of pediatric anesthesia during the early recovery period. Children undergoing ear, nose, and throat surgery are at high risk. The Pediatric Assessment of Emergence Delirium (PAED) scale is used for diagnosis and founded to specify the degree of emergence delirium. However, there is no consensus regarding a threshold value for emergence delirium diagnosis. Homeostasis-guided pediatric general anesthesia aims to maintain physiological parameters within normal ranges. In this prospective, observational study we evaluated the incidence of emergence delirium in children undergoing elective ear, nose, and throat surgery under standardized homeostasis-guided general anesthesia. Secondarily, we identified risk factors associated with an increased PAED score. ⋯ Our cohort observed a lower incidence of emergence delirium than in the literature. Higher pain intensity and lower blood glucose levels were risk factors for PAED > 0, whereas preoperative ketone body levels were protective.
