A Call to Action: Why Anesthesiologists Must Train, Prepare, and Be at the Forefront of Disaster Response for Mass Casualty Incidents.

Disasters, both natural and man-made, continue to increase. In Spring 2023, a 3-hour workshop on mass casualty incidents was conducted at the Society for Pediatric Anesthesia-American Academy of Pediatrics Annual conference. The workshop used multiple instructional strategies to maximize knowledge transfer and learner engagement including minididactic sessions, problem-based learning discussions in 3 tabletop exercises, and 2 30-minute disaster scenarios with actors in a simulated hospital environment. Three themes became evident: (1) disasters will continue to impact hospitals and preparation is imperative, (2) anesthesiologists are extensively and comprehensively trained and their value is often underestimated as mass casualty incident responders, and (3) a need exists for longitudinal disaster preparedness education and training over the course of a career. In this special article, we have sought to further define the problem and evidence, the capacity of anesthesiologists as leaders in disaster preparedness, and the rationale for preparation with current best practices to guide how best to move forward.

Paediatric patients in mass casualty incidents: a comprehensive review and call to action.

The paediatric population is disproportionately affected during mass casualty incidents (MCIs). Several unique characteristics of children merit special attention during natural and man-made disasters because of their age, physiology, and vulnerability. Paediatric anaesthesiologists play a critical part of MCI care for this population, yet there is a deficit of publications within the anaesthesia literature addressing paediatric-specific MCI concerns. This narrative review article analyses paediatric MCI considerations and compares differing aspects between care provision in Australia, the UK, and the USA. We integrate some of the potential roles for anaesthesiologists with paediatric experience, which include preparation, command consultation, in-field care, pre-hospital transport duties, and emergency department, operating theatre, and ICU opportunities. Finally, we propose several methods by which anaesthesiologists can improve their contribution to paediatric MCI care through personal education, training, and institutional involvement.

Predictors of transfusion outcomes in pediatric complex cranial vault reconstruction: a multicentre observational study from the Pediatric Craniofacial Collaborative Group.

PURPOSE: Pediatric patients undergoing complex cranial vault reconstruction (CCVR) are at risk of significant perioperative blood loss requiring blood product transfusion. Minimizing allogeneic blood product transfusion is an important goal because of the associated risks and cost. The impact of patient and surgical variables on transfusion is unknown in this population. Our primary aim was to examine relationships between demographic and perioperative variables and blood product transfusion outcomes in CCVR. METHODS: The multicentre Pediatric Surgery Perioperative Registry was checked for children undergoing CCVR between June 2012 and September 2016. Univariable and multivariable analyses were performed examining patient, procedure, and blood conservation variables and their relationship to three outcomes: intraoperative red blood cell-containing product (RBC-CP) transfusion, total perioperative blood donor exposures, and transfusion-free hospitalization. RESULTS: The registry search returned data from 1,814 cases. Age and surgical duration were the only variables significantly associated with all three outcomes studied. Predictors of reduced RBC-CP transfusion included lower American Society of Anesthesiologists (ASA) physical status and antifibrinolytic administration. Total cranial vault reconstruction, intraoperative vasoactive infusion, and presence of a tracheostomy predicted increased donor exposures. Increased body weight, higher preoperative hematocrit, and utilization of intraoperative cell saver and transfusion protocols were associated with transfusion-free hospitalization. CONCLUSION: Clinical factors associated with increased allogeneic blood product transfusion in pediatric CCVR include: age ≤ 24 months, ASA status ≥ III, preoperative anemia, prolonged surgical duration, lack of intraoperative antifibrinolytic use, lack of intraoperative cell saver use, and the lack of transfusion protocols.

RéSUMé: OBJECTIF: Les patients pédiatriques subissant une reconstruction complexe de la voûte crânienne courent un risque de pertes sanguines périopératoires importantes nécessitant la transfusion de produits sanguins. La minimisation de la transfusion de produits sanguins allogènes constitue un objectif majeur étant donné les risques et les coûts associés. L'impact des variables liées au patient et à la chirurgie sur la transfusion est inconnu dans cette population. Notre objectif principal était d'examiner les liens entre les variables démographiques et périopératoires, et les résultats des transfusions sanguines suite à une reconstruction complexe de la voûte crânienne. MéTHODE: Le Registre périopératoire multicentrique de chirurgie pédiatrique (Pediatric Surgery Perioperative Registry) a été consulté afin d'en extraire les dossiers de tous les enfants ayant subi une reconstruction complexe de la voûte crânienne entre juin 2012 et septembre 2016. Des analyses univariées et multivariées ont été réalisées et ont examiné les variables concernant les patients, l'intervention et la conservation du sang ainsi que les relations entre ces données et trois critères : la transfusion peropératoire de produits contenant des érythrocytes, l'exposition durant toute la période périopératoire aux dons de sang, et l'hospitalisation sans transfusion. RéSULTATS: L'examen du Registre a permis d'extraire les données de 1814 cas. L'âge et la durée de la chirurgie étaient les deux seules variables à afficher une association significative aux trois critères à l'étude. Les prédicteurs d'une transfusion réduite d'érythrocytes étaient un statut physique ASA (American Society of Anesthesiologists) plus bas et l'administration d'agents antifibrinolytiques. La reconstruction totale de la voûte crânienne, la perfusion peropératoire d'agents vasoactifs et la présence d'une trachéostomie constituaient des prédicteurs d'exposition plus importante aux dons de sang. Un poids corporel accru, un hématocrite préopératoire plus élevé et l'utilisation de systèmes d'autotransfusion peropératoire et de protocoles de transfusion étaient associés à une hospitalisation sans transfusion. CONCLUSION: Les facteurs cliniques associés à une augmentation des transfusions de produits sanguins allogènes dans les cas de reconstruction complexe de la voûte crânienne chez l'enfant sont : un âge ≤ 24 mois, un statut ASA ≥ III, une anémie préopératoire, la durée prolongée de la chirurgie, l'absence d'utilisation peropératoire d'antifibrinolytiques, l'absence d'utilisation de systèmes d'autotransfusion peropératoire, et l'absence de protocoles de transfusion.

Endoscopic Versus Open Repair for Craniosynostosis in Infants Using Propensity Score Matching to Compare Outcomes: A Multicenter Study from the Pediatric Craniofacial Collaborative Group.

BACKGROUND: The North American Pediatric Craniofacial Collaborative Group (PCCG) established the Pediatric Craniofacial Surgery Perioperative Registry to evaluate outcomes in infants and children undergoing craniosynostosis repair. The goal of this multicenter study was to utilize this registry to assess differences in blood utilization, intensive care unit (ICU) utilization, duration of hospitalization, and perioperative complications between endoscopic-assisted (ESC) and open repair in infants with craniosynostosis. We hypothesized that advantages of ESC from single-center studies would be validated based on combined data from a large multicenter registry. METHODS: Thirty-one institutions contributed data from June 2012 to September 2015. We analyzed 1382 infants younger than 12 months undergoing open (anterior and/or posterior cranial vault reconstruction, modified-Pi procedure, or strip craniectomy) or endoscopic craniectomy. The primary outcomes included transfusion data, ICU utilization, hospital length of stay, and perioperative complications; secondary outcomes included anesthesia and surgical duration. Comparison of unmatched groups (ESC: N = 311, open repair: N = 1071) and propensity score 2:1 matched groups (ESC: N = 311, open repair: N = 622) were performed by conditional logistic regression analysis. RESULTS: Imbalances in baseline age and weight are inherent due to surgical selection criteria for ESC. Quality of propensity score matching in balancing age and weight between ESC and open groups was assessed by quintiles of the propensity scores. Analysis of matched groups confirmed significantly reduced utilization of blood (26% vs 81%, P < .001) and coagulation (3% vs 16%, P < .001) products in the ESC group compared to the open group. Median blood donor exposure (0 vs 1), anesthesia (168 vs 248 minutes) and surgical duration (70 vs 130 minutes), days in ICU (0 vs 2), and hospital length of stay (2 vs 4) were all significantly lower in the ESC group (all P < .001). Median volume of red blood cell administered was significantly lower in ESC (19.6 vs 26.9 mL/kg, P = .035), with a difference of approximately 7 mL/kg less for the ESC (95% confidence interval for the difference, 3-12 mL/kg), whereas the median volume of coagulation products was not significantly different between the 2 groups (21.2 vs 24.6 mL/kg, P = .73). Incidence of complications including hypotension requiring treatment with vasoactive agents (3% vs 4%), venous air embolism (1%), and hypothermia, defined as <35°C (22% vs 26%), was similar between the 2 groups, whereas postoperative intubation was significantly higher in the open group (2% vs 10%, P < .001). CONCLUSIONS: This multicenter study of ESC versus open craniosynostosis repair represents the largest comparison to date. It demonstrates striking advantages of ESC for young infants that may result in improved clinical outcomes, as well as increased safety.

The Post-Anesthetic Care of Pediatric Patients With Pulmonary Hypertension.

Few conditions make even the most experienced pediatric anesthesiologists take pause. Pulmonary hypertension is one such condition due to the associated high perioperative morbidity and mortality. Much is written about the intraoperative management of pediatric pulmonary hypertension. This article will instead focus on postoperative care and review the evidence in support of a risk stratification approach for the post-anesthetic disposition of these patients. The total risk for post-anesthetic adverse events includes the patient's baseline risk factors and the incremental risks imposed by the procedure and anesthetic. A proposal with recommendations to guide practitioners and a table summarizing relevant factors are provided. Last, the readers' attention is drawn to the heterogeneity of pulmonary hypertensive disease. Pulmonary arterial hypertension (precapillary) differs significantly from pulmonary venous hypertension (postcapillary); the anesthetic management for one may be relatively contraindicated in the other. Their dissimilarities justify the need to distinguish them for study and research endeavors.

Management of preterm giant sacrococcygeal teratoma (GSCT) with an excellent outcome.

Infants born with a giant sacrococcygeal teratoma (GSCT; >10 cm) have high mortality. Risk factors for mortality include increased tumor vascularity, high cardiac output, rapid growth, diagnosis before 20-week gestation, delivery before 30-week gestation, hydrops, low birth weight, Apgar less than 7 at 5 min and polyhydramnios. We present the case of a 28-week infant born with a GSCT (15 × 12 × 16 cm) and all of these risk factors.
