The association between intraoperative fluid management and perioperative allogenic blood transfusion during adolescent idiopathic scoliosis surgery.
Bleeding and transfusion remain important concerns during surgical correction of scoliosis even when multiple conservative strategies, such as preoperative recombinant erythropoietin and/or antifibrinolytic agents, are used. The current work aimed to determine the impact of other potential risk factors, especially the volume of intraoperative fluid intake, on the perioperative risk of allogenic transfusion during surgical correction of adolescent idiopathic scoliosis. ⋯ These results indicate a statistical association between the increase in crystalloid intake and the risk of allogenic blood transfusion during surgical correction of adolescent idiopathic scoliosis. Controlled studies are needed to address the causative relation between intraoperative fluid intake and the risk of allogenic transfusion.

Benefits and challenges of combined pediatrics-anesthesiology residency programs: A qualitative study.
The combined pediatrics-anesthesiology residency program was created in 2011 for trainees interested in careers within both specialties. Prior studies have cited challenges of combined training, but none have systematically identified benefits. ⋯ This is the first study to describe the perceived educational and professional benefits of combined pediatrics-anesthesiology residency programs. Combined training affords exceptional clinical competence and autonomy in the management of pediatric patients and the ability to skillfully navigate hospital systems, and leads to robust academic and career opportunities. However, the duration of training and challenging transitions may threaten residents' sense of relatedness to colleagues and peers, and their self-perceived competence and autonomy. These results can inform mentoring and recruitment of residents to combined pediatrics-anesthesiology programs and career opportunities for graduates.

Observational StudyFunctional near-infrared spectroscopy guided mapping of frontal cortex, a novel modality for assessing emergence delirium in children: A prospective observational study.
Despite an 18%-30% prevalence, there is no consensus regarding pathogenesis of emergence delirium after anesthesia in children. Functional near-infrared spectroscopy (fNIRS) is an optical neuroimaging modality that relies on blood oxygen level-dependent response, translating to a mean increase in oxyhemoglobin and a decrease in deoxyhemoglobin. We aimed to correlate the emergence delirium in the postoperative period with the changes in the frontal cortex utilizing fNIRS reading primarily and also with blood glucose, serum electrolytes, and preoperative anxiety scores. ⋯ There is significant difference in the change in oxyhemoglobin concentration during induction, maintenance, and emergence in specific frontal brain regions between children with and without emergence delirium.

Effect of central venous pressure on fluid delivery during start-up of syringe infusion pumps for microinfusion.
Intravenous administration of highly concentrated and potent drugs at low flow rates is common practice, particularly in critically ill children. Drug delivery during infusion start-up can be considerably delayed by intrinsic factors of syringe infusion pump assemblies. The impact of central venous pressures on the course of start-up fluid delivery of such microinfusions remains unknown. ⋯ Depending on central venous pressure level, connection and starting a new syringe pump can result in significant antegrade or retrograde fluid volumes. In clinical practice, this can lead to hemodynamic instability and hence requires clinical alertness. Further research and methods to improve start-up performance in syringe infusion pump systems are desirable.
