Review Meta Analysis
Opioid-free anesthesia: A systematic review and meta-analysis.
To evaluate all available evidence thus far on opioid based versus opioid-free anesthesia and its effect on acute and chronic postoperative pain. ⋯ We concluded that we cannot recommend one strategy over the other. Future studies could focus on quality of recovery as outcome measure and adequately powered studies on the effects of opioid-free anesthesia on chronic pain are eagerly awaited.

Multicenter Study
The impact of residency training level on early postoperative desaturation: A retrospective multicenter cohort study.
We studied the primary hypothesis that the training level of anesthesiology residents (first clinical anesthesia year, CA1 vs CA2/3 residents) is associated with early postoperative desaturation (oxygen saturation < 90%). We also analyzed the change in the rate (trajectory) of desaturation during the resident's development from CA1 to CA2/3 resident, and its effects on postoperative respiratory complications. ⋯ Patients treated by CA1 residents have an increased risk of postoperative desaturation. Some residents show an improvement and others a decline in postoperative desaturation rate. Our secondary analysis suggests that there should be more focus on those residents who had a declining performance in postoperative desaturation despite becoming more experienced.

Randomized Controlled Trial
Comparison of propofol vs. remimazolam on emergence profiles after general anesthesia: A randomized clinical trial.
The emergence profiles in patients undergoing total intravenous anesthesia with either propofol or remimazolam with flumazenil reversal were compared. ⋯ Remimazolam-based total intravenous anesthesia with flumazenil reversal may be effective in reducing emergence time, but a significant incidence of re-sedation was observed in the PACU. Further studies are needed to determine adequate dose and timing of routine flumazenil use and minimize the risk of re-sedation.

Randomized Controlled Trial
Cost effectiveness and long-term outcomes of dexamethasone administration in major non-cardiac surgery.
Postoperative administration of dexamethasone has been proposed to reduce morbidity and mortality in patients undergoing major non-cardiac surgery. In this ancillary study of the PACMAN trial, we aimed to evaluate the cost effectiveness of dexamethasone in patients undergoing major non-cardiac surgery. ⋯ Of 1222 randomized patients in PACMAN, 137 patients (11%) were followed up until 12 months after major surgery (71 in the DXM group and 66 in the placebo group). Postoperative dexamethasone administration reduced costs per patient at 1 year by €358.06 (95%CI -€1519.99 to €803.87). The probability of dexamethasone being cost effective was between 12% and 22% for a willingness to pay of €100,000 to €150,000 per life-year, which is the threshold that is usually used in France and was 52% for willingness to pay of €50,000 per life-year (threshold in USA). At 12 months, 9 patients (13.2%) in the DXM group and 10 patients (16.1%) in the placebo group had died. In conclusion, our study does not demonstrate the cost effectiveness of perioperative administration of DXM in major non-cardiac surgery.

To measure the incidence of intraoperative hypotension (IOH) during surgery in ambulatory surgery centers (ASCs) and describe associated characteristics of patients and procedures. ⋯ There was substantial occurrence of IOH in ASCs, similar to that described in academic hospital settings in previous literature. We hypothesize that this may reflect clinician preference not to intervene in perceived healthy patients or assumptions about ability to tolerate lower blood pressures on behalf of these patients. Future research will determine whether IOH in ACSs is associated with adverse outcomes to the same extent as described in more complex hospital-based surgeries.
