Multicenter Study Observational Study
Associations of intraoperative end-tidal CO2 levels with postoperative outcome-secondary analysis of a worldwide observational study.
Patients receiving intraoperative ventilation during general anesthesia often have low end-tidal CO2 (etCO2). We examined the association of intraoperative etCO2 levels with the occurrence of postoperative pulmonary complications (PPCs) in a conveniently-sized international, prospective study named 'Local ASsessment of Ventilatory management during General Anesthesia for Surgery' (LAS VEGAS). ⋯ LAS VEGAS was registered at Clinicaltrials.gov (NCT01601223), first posted on May 17, 2012.

Randomized Controlled Trial Multicenter Study
Reduction of postoperative pain and opioid consumption by VVZ-149, first-in-class analgesic molecule: A confirmatory phase 3 trial of laparoscopic colectomy.
VVZ-149 is a small molecule that inhibits the glycine transporter type 2 and the serotonin receptor 5-hydroxytryptamine 2 A. In this Phase 3 study, we investigated the efficacy and safety of VVZ-149 as a single-use injectable analgesic for treating moderate to severe postoperative pain after laparoscopic colectomy. ⋯ Trial Number NCT05764525.

Multicenter Study
Intraoperative FiO2 and risk of impaired postoperative oxygenation in lung resection: A propensity score-weighted analysis.
To assess whether, in a lung resection cohort with a low probability of confounding by indication, higher FiO2 is associated with an increased risk of impaired postoperative oxygenation - a clinical manifestation of lung injury/dysfunction. ⋯ Despite plausible harm from hyperoxia, high intraoperative FiO2 is extremely common during lung resection. Nearly three-quarters of lung resection patients with acceptable oxygenation received median intraoperative FiO2 ≥ 0.8. Such higher FiO2 was associated with an increased risk of impaired postoperative oxygenation - a clinically relevant manifestation of lung injury or dysfunction. This observation supports the administration of a lower (< 0.8) intraoperative FiO2 and its further assessment in clinical trials.

Randomized Controlled Trial Multicenter Study
Personalized perioperative blood pressure management in patients having major non-cardiac surgery: A bicentric pilot randomized trial.
We hypothesize that personalized perioperative blood pressure management maintaining intraoperative mean arterial pressure (MAP) above the preoperative mean nighttime MAP reduces perfusion-related organ injury compared to maintaining intraoperative MAP above 65 mmHg in patients having major non-cardiac surgery. Before testing this hypothesis in a large-scale trial, we performed this bicentric pilot trial to determine a) if performing preoperative automated nighttime blood pressure monitoring to calculate personalized intraoperative MAP targets is feasible; b) in what proportion of patients the preoperative mean nighttime MAP clinically meaningfully differs from a MAP of 65 mmHg; and c) if maintaining intraoperative MAP above the preoperative mean nighttime MAP is feasible in patients having major non-cardiac surgery. ⋯ It seems feasible to determine the effect of personalized perioperative blood pressure management maintaining intraoperative MAP above the preoperative mean nighttime MAP on postoperative complications in a large multicenter trial.

Multicenter Study Observational Study
Patient/anesthesiologist intersubjective experiences and intravenous supplementation during elective cesarean delivery: A prospective patient-reported outcome study.
This prospective, observational study investigated the impact of patient/anesthesiologist interactions and socioeconomic factors on administering intravenous analgesics and anxiolytics during elective Cesarean delivery under spinal anesthesia. The study explored the role of emotional experiences and psychosocial characteristics on intraoperative administration of intravenous adjuncts. ⋯ The study revealed a substantial gap between patient requests for analgesics and their administration, as well as an overreliance on anxiolysis compared to analgesia. Unconscious attitudes related to patient factors and subjective physician perceptions played a role in medication decisions. The findings emphasize the need for better pain assessment and management training, and awareness of implicit biases in healthcare settings. Future research should investigate optimal communication strategies and address unconscious attitudes to improve patient-centered care.
