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

Oxygen delivery through a Frova Intubating Introducer may be life-saving, and gas flow characteristics through this device have been described. Nevertheless, the feasibility of using a self-inflating resuscitation bag to deliver air or oxygen through this device has not been assessed. We compared volumes of air delivered and peak pressures generated with normal and maximal bimanual compression of a self-inflating resuscitation bag connected to a 70 cm Frova Intubating Introducer. ⋯ Clinically useful, life-sustaining volumes of air can be delivered using normal and maximal bimanual compression of a self-inflating resuscitation bag connected to a 70 cm Frova Intubating Introducer.

Females remain under-represented in academic anesthesiology. Our objectives were to investigate gender differences over time in the first and last authors of published articles as well as corresponding citation rates in the Canadian Journal of Anesthesia (CJA). ⋯ Our study shows that, despite a slow increase over time, female authors are under-represented relative to male authors in the CJA and relative to the changing demographics of anesthesiologists in Canada. The reasons for this disparity are multifactorial and further research is needed to identify effective solutions.

This narrative review discusses the incidence, risk factors, mechanisms of injury, complications, and treatment regimens for accidental intra-arterial injection of medications. Despite awareness of the issue and the establishment of safety recommendations by national agencies, accidental iatrogenic intra-arterial injection of medications continues to occur. Most of these injuries are caused by accidental injection into an established arterial cannula or the inadvertent and unrecognized cannulation of an artery instead of a vein. ⋯ While the characteristics of injuries from illicit injections are diverse and the optimal treatment modalities are still uncertain, a regimen that includes anticoagulation and intra-arterial injection of thrombolytics and prostaglandins may improve outcomes. Steroids, vasodilators, and sympathetic blocks do not appear to influence amputation rates. Owing to the small and sporadic number of cases, no definitive clinical trial evidence exists, but the treatment modalities found to be useful in the illicit intra-arterial injection group may benefit treatment of similar iatrogenic injuries.
