Randomized Controlled Trial
Effect of a pre-emptive 2-hour session of high-flow nasal oxygen on postoperative oxygenation after major gynaecologic surgery: a randomised clinical trial.
We aimed at determining whether a 2-h session of high-flow nasal oxygen (HFNO) immediately after extubation improves oxygen exchange after major gynaecological surgery in the Trendelenburg position in adult female patients. ⋯ NCT04566419.

ReviewModulating anesthetic emergence with pathway-selective dopamine signaling.
To summarize the recent preclinical findings investigating dopaminergic circuits for their involvement in reversing anesthetic-induced unconsciousness. ⋯ Potential avenues for accelerating anesthetic emergence may be found through targeting specific arousal-promoting pathways in the brain. Accumulating evidence from rodent studies manipulating cell type- and circuit-specific signaling pathways have identified dopamine as a potent modulator of general anesthesia. Specifically, dopamine signaling along the mesolimbic and mesocortical pathways plays a fundamental role in regulating consciousness.

Patients with mastocytosis have an increased risk of anaphylaxis during surgical procedures with general anesthesia. Therefore, we reviewed the anesthesia course of a large cohort of patients with mastocytosis. ⋯ Intraoperative anaphylaxis can be the first presenting sign of mastocytosis. Patients with mastocytosis who received chronic antimediator therapy and/or preoperative prophylactic medications had an uneventful surgical course.

Observational StudyEvaluation of quality of care in neonatal anesthesia using a bundle of intraoperative parameters.
Maintenance of physiological homeostasis is key in the safe conduct of pediatric anesthesia. Achieving this goal is especially difficult in neonatal surgery. ⋯ Although a median of six out of the seven selected intraoperative parameters were monitored during gastroschisis repair, only two of them (oxygen saturation and heart rate) were maintained within the pre-defined range more than 80% of the time. It might be of interest to extend physiologic age- and procedure-based approach to the development of specific preoperative anesthetic planning.

Observational StudyMonitoring anesthesia depth with patient state index during pediatric surgery.
Monitoring anesthesia depth in children is challenging. Pediatric anesthesiologists estimate general anesthesia depth using indirect methods such as pharmacokinetic models and neurovegetative reflexes. The application of processed electroencephalography may help to identify the correct anesthesia depth (i.e., patient state index between 25 and 50). ⋯ NonpEEG-guided anesthesia in children led to median patient state index levels at the low range of recommended unconsciousness values with frequent episodes of burst suppression. Patient state index levels were generally higher in children below 2 years.
