Endotracheal Oxygen Insufflation Associated with Life-Threatening Barotrauma during Apnea Testing.

Apnea testing is a standard method when diagnosing brain or more specifically brainstem death; however, it is imperative to acknowledge the potential for lung injury during this procedure and follow clinical practice guideline recommendations that may reduce the risk of complications. Two cases of barotrauma leading to pneumothorax occurred during apnea tests that used higher-than-recommended oxygen flow rates. Additional data are necessary to clarify the mechanism and incidence of this life-threatening complication.

Determining the optimal time for liberation from renal replacement therapy in critically ill patients: a systematic review and meta-analysis (DOnE RRT).

Introduction: Renal replacement therapy (RRT) is associated with high mortality and costs; however, no clinical guidelines currently provide specific recommendations for clinicians on when and how to stop RRT in recovering patients. Our objective was to systematically review the current evidence for clinical and biochemical parameters that can be used to predict successful discontinuation of RRT.

Methods: A systematic review and meta-analysis were performed with a peer-reviewed search strategy combining the themes of renal replacement therapy (IHD, CRRT, SLED), predictors of successful discontinuation or weaning (defined as an extended period of time free from further RRT), and patient outcomes.

Determining the optimal time for liberation from renal replacement therapy in critically ill patients: protocol for a systematic review and meta-analysis (DOnE RRT).

Introduction: Renal replacement therapy (RRT) is a complex and expensive form of life-sustaining therapy, reserved for our most acutely ill patients. While a number of randomised trials have evaluated the optimal timing to start RRT among critically ill patients in the intensive care unit (ICU), there has been a paucity of trials providing guidance on when and under what circumstances to ideally liberate a patient from RRT. We are conducting a systematic review and meta-analysis to identify clinical and biochemical markers that predict kidney recovery and successful liberation from acute RRT among critically ill patients with acute kidney injury.
