Decline of Pediatric Ambulatory Surgery Cases Performed at Florida General Hospitals Between 2010 and 2018: An Historical Cohort Study.
In the province of Ontario, nonphysiologically complex surgical procedures have increased at 4 pediatric hospitals with a reciprocal decline among the other (general) hospitals performing pediatric surgery. Given the differences between the Canadian and US health systems, we studied whether a similar shift occurred in the state of Florida and examined the age dependence of the shift. ⋯ The decline across all age groups was inconsistent with multiple general hospitals increasing their minimum age threshold for surgical patients because, otherwise, the younger patients would have accounted for a larger share of the decreases in caseload. Pediatric hospitals and their anesthesiologists have greater surgical growth than expected from population demographics. Many general hospitals can expect either needing fewer pediatric anesthesiologists or that their pediatric anesthesiologists, who also care for adults, will have smaller proportions of pediatric patients in their practices.

Using the 12-item World Health Organization Disability Assessment Schedule (WHODAS-12), we measured the prevalence of disability in all eligible patients during a 4-month period who were presenting for preoperative evaluation at a US Veterans Affairs hospital. Overall disability was at least moderate in more than half of these patients (total n = 472 at Durham, NC). Two of the 6 WHODAS domains, "Getting Around" and "Participation in Society," contributed most to the overall scores-25% and 20%, respectively. Further studies are needed to determine the impact of domain-specific disabilities on postoperative outcomes and to identify potential interventions to address these vulnerabilities.

Observational StudyThromboelastographic Assessment of Fibrinolytic Activity in Postpartum Hemorrhage: A Retrospective Single-Center Observational Study.
Postpartum hemorrhage is a leading cause of maternal mortality. Antifibrinolytic therapy has the potential to influence outcomes in postpartum hemorrhage, but the incidence of elevated fibrinolytic activity in postpartum hemorrhage is unknown. ⋯ Our observation that none of the patients in our sample with kaolin TEG Ly30 values ≥3% had a nonzero functional fibrinogen TEG Ly30 value suggests that the observed elevations in kaolin TEG Ly30 may have been secondary to platelet-mediated clot retraction as opposed to fibrinolysis. Platelet-mediated clot retraction should be distinguished from fibrinolysis when assayed using viscoelastic techniques in postpartum hemorrhage. Further research is necessary to determine the optimal methods to assess fibrinolytic activity in postpartum hemorrhage.

Analysis of 1478 Cases of Hypospadias Repair: The Incidence of Requiring Repeated Anesthetic Exposure as Well as Exploration of the Involvement of Trainees on Case Duration.
Recently, there has been significant focus on the effects of anesthesia on the developing brain. Concern is heightened in children <3 years of age requiring lengthy and/or multiple anesthetics. Hypospadias correction is common in otherwise healthy children and may require both lengthy and repeated anesthetics. At academic centers, many of these cases are performed with the assistance of anesthesia and surgical trainees. We sought to identify both the incidence of these children undergoing additional anesthetics before age 3 as well as to understand the effect of trainees on duration of surgery and anesthesia and thus anesthetic exposure (AE), specifically focusing on those cases >3 hours. ⋯ The majority of children with hypospadias were repaired within a single AE. In general, most children did not require repeated AE before age 3. While presence of nonattending surgeons was associated with an increase in AE, this might at least partially be due to differences in case complexity. Moreover, the increase is likely not clinically significant. While it is critical to maintain a training environment, attempts to minimize AE are crucial. This information facilitates parental consent, particularly with regard to anesthesia duration and the need for additional anesthetics in hypospadias and nonhypospadias surgeries.

Propofol Attenuates Isoflurane-Induced Neurotoxicity and Cognitive Impairment in Fetal and Offspring Mice.
Anesthesia in pregnant rodents causes neurotoxicity in fetal and offspring rodents. However, the underlying mechanisms and targeted treatments remain largely to be determined. Isoflurane and propofol are among commonly used anesthetics. Thus, we set out to investigate whether propofol can mitigate the isoflurane-induced neurotoxicity in mice. ⋯ These findings suggest that gestational isoflurane exposure in mice induces neuroinflammation and apoptosis in embryos and causes cognitive impairment in offspring. Propofol can attenuate these isoflurane-induced detrimental effects.
