The use of prothrombin complex concentrate as a warfarin reversal agent in pediatric patients undergoing orthotopic heart transplantation.
Patients supported with a ventricular assist device are predisposed to severe bleeding at the time of orthotopic heart transplant due to several risk factors including anticoagulation with vitamin K antagonists. Kcentra, a four-factor prothrombin complex concentrate, has been approved by the FDA for warfarin reversal in adults prior to urgent surgery. There is a lack of published data on the preoperative use of four-factor prothrombin complex concentrates in pediatric patients undergoing cardiacsurgery. ⋯ This small retrospective study indicates that preoperative warfarin reversal with Kcentra reduces blood product exposure in pediatric patients with ventricular assist devices undergoing heart transplant.

Observational StudyEvaluation of Noninvasive Hemoglobin Monitoring in Children with Congenital Heart Diseases.
Noninvasive measurement of blood hemoglobin could save time and decrease the risk of anemia and infection. The accuracy of CO-oximetry-derived noninvasive hemoglobin (Sp-Hb) had been evaluated in pediatric population; however, its accuracy in children with congenital heart disease has not been studied till date. We evaluated the accuracy of Sp-Hb in relation to laboratory-measured hemoglobin (Lab-Hb) in children with congenital heart disease. ⋯ The large bias and the wide limits of agreement between Sp-Hb and Lab-Hb denote that Masimo-derived Sp-Hb is not accurate in children with congenital heart disease especially in the cyanotic group; the error in Sp-Hb increases when oxygen saturation decreases.

Peters anomaly is a rare, congenital eye malformation characterized by an opaque cornea and blurred vision. Central corneal opacification can lead to delayed progression of visual development caused by defects in Descemet membrane and the posterior stroma. These children require several anesthetics for multiple eye examinations under anesthesia and corneal transplantation. ⋯ Although limited by its retrospective nature, this case series describes the cardiac and systemic implications of patients undergoing anesthesia with Peters anomaly. Our experience indicates that general anesthesia and airway manipulation are tolerated with minor postoperative concerns in these infants. Pediatric patients with Peters anomaly require multiple anesthetics for repeated ophthalmologic interventions. The laryngeal mask airway can be routinely utilized in infants less than 3 months of age for an eye examination under anesthesia with no airway complications noted. Perioperative providers should be aware of the multisystemic implications in patients with Peters plus syndrome.
