Meta AnalysisRisk Factors for Postanesthetic Emergence Delirium in Adults: A Systematic Review and Meta-analysis.
Emergence delirium (ED) is delirium that occurs during or immediately after emergence from general anesthesia or sedation. Effective pharmacological treatments for ED are lacking, so preventive measures should be taken to minimize the risk of ED. However, the risk factors for ED in adults are unclear. ⋯ Postoperative risk factors were indwelling urinary catheters, the presence of a tracheal tube in the postanesthetic care unit or intensive care unit, the presence of a nasogastric tube, and pain. Knowledge of these risk factors may guide the implementation of stratified management and timely interventions for patients at high risk of ED. The majority of studies included in this review investigated only hyperactive ED and further research is required to determine risk factors for hypoactive and mixed ED types.

Events occurring after randomization, such as use of rescue medication, treatment discontinuation, or death, are common in randomized trials. These events can change either the existence or interpretation of the outcome of interest. ⋯ This article describes how the estimand framework can be used in anesthesia trials to precisely define the treatment effect to be estimated, key attributes of an estimand, common intercurrent events in anesthesia trials with strategies for handling them, and use of the estimand framework in a hypothetical anesthesia trial on postoperative delirium. When planning anesthesia trials, clearly defining the estimand is vital to ensure that what is being estimated is clearly understood, is clinically relevant, and helps answer the clinical questions of interest.
