Patient and Operative Factors Predict Risk of Discretionary Prolonged Postoperative Mechanical Ventilation in a Broad Surgical Cohort.
Patients undergoing surgery with general anesthesia and endotracheal intubation are ideally extubated upon case completion, as prolonged postoperative mechanical ventilation (PPMV) has been associated with poor outcomes. However, some patients require PPMV for surgical reasons, such as airway compromise, while others remain intubated at the discretion of the anesthesia provider. Incidence and risk factors for discretionary PPMV (DPPMV) have been described in individual surgical subspecialties and intensive care unit (ICU) populations, but are relatively understudied in a broad surgical cohort. The present study seeks to fill this gap and identify the perioperative risk factors that predict DPPMV. ⋯ DPPMV was uncommon in this broad surgical cohort but could be accurately predicted using readily available patient-specific and operative factors. These results may be useful for preoperative risk stratification, postoperative resource allocation, and clinical trial planning.

Randomized Controlled TrialBenefit of Flow-Controlled Over Pressure-Regulated Volume Control Mode During One-Lung Ventilation: A Randomized Experimental Crossover Study.
Application of a ventilation modality that ensures adequate gas exchange during one-lung ventilation (OLV) without inducing lung injury is of paramount importance. Due to its beneficial effects on respiratory mechanics and gas exchange, flow-controlled ventilation (FCV) may be considered as a protective alternative mode of traditional pressure- or volume-controlled ventilation during OLV. We investigated whether this new modality provides benefits compared with conventional ventilation modality for OLV. ⋯ The application of FCV in OLV led to improvement in gas exchange and respiratory elastance with lower ventilatory pressures. Our findings suggest that FCV may offer an optimal, protective ventilation modality for OLV.

Age-Stratified Propofol Dosage for Pediatric Procedural Sedation and Analgesia.
Procedural sedation and analgesia (PSA) for diagnostic and minimally invasive therapeutic procedures has become common practice in children of all ages. Based on our clinical experience, we suspected an inverse relation between age and dosage. However, a schedule for age-stratified propofol induction and maintenance dosage for PSA was not available and could be helpful to many anesthesiologists as a reference. ⋯ We found a noteworthy inverse age-effect on propofol dosage for both induction and maintenance of pediatric procedural sedation. Furthermore, our study revealed that remarkably higher propofol sedation doses were needed for infants and toddlers than previously expected and reported.

Perioperative Tracking of Intravenous Iron in Patients Undergoing On-Pump Cardiac Surgery: A Prospective, Single-Center Pilot Trial.
Preoperative intravenous iron administration is a frequently used patient blood management procedure. If the timeframe of intravenous iron administration before surgery is short, (1) the concentration of the intravenous iron compound might still be high in patients' plasma when undergoing surgery and (2) this iron in patients' plasma is at risk to be lost due to blood loss. The aim of the current study was, therefore, to track the iron compound ferric carboxymaltose (FCM) before, during, and after cardiac surgery requiring cardiopulmonary bypass, with an emphasis on intraoperative iron losses in shed blood and potential recovery through autologous cell salvage. ⋯ The data generate the hypotheses that nearly all FCM is incorporated into iron stores with administration ≥48 hours before surgery. When FCM is given <48 hours of surgery, the majority is incorporated into iron stores by the time of surgery, although a small amount may be lost during surgical bleeding with limited recovery by cell salvage.

A Consensus-Driven Approach to Redesigning Graduate Medical Education: The Pediatric Anesthesiology Delphi Study.
Pediatric anesthesiology fellowship education has necessarily evolved since Accreditation Council for Graduate Medical Education (ACGME) accreditation in 1997. Advancements in perioperative and surgical practices, emerging roles in leadership, increasing mandates by accreditation and certification bodies, and progression toward competency-based education-among other things-have created pressure to enrich the current pediatric anesthesiology training system. The Society for Pediatric Anesthesia (SPA) formed a Task Force for Pediatric Anesthesiology Graduate Medical Education that included key leaders and subject matter experts from the society. A key element of the Task Force's charge was to identify curricular and evaluative enhancements for the fellowship program of the future. ⋯ A Delphi process achieved robust consensus in assessing current training and recommending future directions for pediatric anesthesiology graduate medical education.
