Postoperative complications after central nervous system tumor resection in pediatric patients admitted to an intensive care unit in Colombia.

Introduction: Central nervous system (CNS) tumors are the second most prevalent malignant neoplasms in childhood, with surgical resection as the primary therapeutic approach. The immediate postoperative period following CNS tumor resection requires intensive care to mitigate complications associated with high morbidity and mortality.

Objective: The primary aim of this study is to comprehensively describe the postoperative complications observed in pediatric patients who underwent primary CNS tumor resection and were subsequently admitted to the pediatric intensive care unit (PICU) at Hospital Universitario Fundación Valle del Lili in Colombia.

Successful Use of Intraoperative Modified Valsalva Maneuver for Atrial Flutter Reversal in Pediatric Cardiac Surgery: Case Report and Review of Literature.

This case report describes the successful use of an intraoperative modified Valsalva maneuver to reverse atrial flutter in a pediatric patient with complex congenital heart disease undergoing systemic-to-pulmonary shunt surgery. The technique involved manipulating the Adjustable Pressure Limiting (APL) valve on the anesthesia machine to simulate the hemodynamic effects of the modified Valsalva maneuver, allowing for non-invasive management of supraventricular tachycardia without pharmacological intervention or electrical cardioversion. This intervention stabilized the patient's arrhythmia, maintaining hemodynamic stability throughout the procedure.
