Acute respiratory failure during pediatric anesthesia: atelectasis and hypertensive pneumothorax: case report.

Background And Objectives: The main anesthesiologist's task is to ensure appropriate oxygenation of patient. The objective of this report is to describe both diagnosis and behavior in case of acute respiratory failure during anesthesia, with educational purposes.

Case Report: Three-year-old child underwent anesthesia for urologic surgery presented respiratory failure by bronchial obstruction by secretion, evolving to atelectasis and hypertensive pneumothorax.

Intraoperative lactate measurements are not predictive of death in high risk surgical patients.

Objectives: An increased lactate level is classically considered a marker for poorer prognosis, however little information is available on intraoperative lactate's kinetics and its connection with prognosis. This study aimed to evaluate the time when perioperative lactate is most relevant for prognosis.

Methods: This was an observational prospective study conducted in a tertiary hospital.
