The majority of pediatric surgeries are performed in a day surgery setting. The rate of adverse postoperative outcomes and the factors that influence them are poorly described in the Canadian setting. Concerns about the safety of adenotonsillectomy (AT) have been raised. The objective of this Ontario-based study was to determine the rates and risks of hospital readmission, emergency department (ED) visits, or deaths within 30 days following common pediatric surgeries, with an emphasis on AT. ⋯ Post-discharge readmissions and ED visits are relatively common after pediatric surgery, particularly for AT. Perioperative treatment algorithms that consider risk factors for hospital revisits are required in children.

The purpose of this study was to determine the contractile patterns induced by oxytocin in myometrium exposed to magnesium sulfate (MgSO4). We hypothesized that MgSO4pretreatment would reduce oxytocin-induced myometrial contractions in both oxytocin-naïve and oxytocin-desensitized myometrium. ⋯ Magnesium sulfate pretreatment does not impair oxytocin-induced myometrial contractility in oxytocin-naïve or desensitized myometrium unless it is continued during oxytocin dose-response testing. These results suggest that its tocolytic effect is likely dependent on an extracellular mechanism. The study was registered with ClinicalTrials.gov, number NCT02647268.

Perioperative antibiotics decrease rates of surgical-site infections. Numerous interventions have improved administration of the first antibiotic dose; however, failures in the administration of subsequent doses frequently occur. We hypothesized that modifications to the electronic medical record (EMR) would improve the administration of the second antibiotic dose and that such improvements would be sustained over time. ⋯ These inexpensive nonintrusive interventions to the EMR provided modest lasting improvements in proper administration of repeated doses of cefazolin. The fact that only approximately 70% compliance was reached highlights the difficulty in addressing this deficiency.
