Physiologic Evaluation of Ventilation Perfusion Mismatch and Respiratory Mechanics at Different Positive End-expiratory Pressure in Patients Undergoing Protective One-lung Ventilation

Authors: Savino Spadaro, M.D., Ph.D. et al Anesthesiology 3 2018, Vol.128, 531-538. Background: Arterial oxygenation is often impaired during one-lung ventilation, due to both pulmonary shunt and atelectasis. The use of low tidal volume (VT) (5 ml/kg predicted body weight) in the context of a lung-protective approach exacerbates atelectasis. This study sought to determine the combined physiologic effects […]

Four Types of Pulse Oximeters Accurately Detect Hypoxia during Low Perfusion and Motion

Authors: Aaron Louie, B.S. et al Anesthesiology 3 2018, Vol.128, 520-530. Background: Pulse oximeter performance is degraded by motion artifacts and low perfusion. Manufacturers developed algorithms to improve instrument performance during these challenges. There have been no independent comparisons of these devices. Methods: We evaluated the performance of four pulse oximeters (Masimo Radical-7, USA; Nihon Kohden OxyPal Neo, […]

Effect of Thoracic Epidural Ropivacaine versus Bupivacaine on Lower Urinary Tract Function: A Randomized Clinical Trial

Authors: Stefan A. Girsberger, M.D. et al Anesthesiology 3 2018, Vol.128, 511-519. Background: Thoracic epidural analgesia with bupivacaine resulted in clinically relevant postvoid residuals due to detrusor underactivity. This study aimed to compare the risk of bladder dysfunction with ropivacaine versus bupivacaine using postvoid residuals and maximum flow rates. Our hypothesis was that ropivacaine would result in lower postvoid […]

Temporal Trends in Difficult and Failed Tracheal Intubation in a Regional Community Anesthetic Practice

Authors: Rebecca A. Schroeder, M.D. et al Anesthesiology 3 2018, Vol.128, 502-510. Background: When tracheal intubation is difficult or unachievable before surgery or during an emergent resuscitation, this is a critical safety event. Consensus algorithms and airway devices have been introduced in hopes of reducing such occurrences. However, evidence of improved safety in clinical practice related to […]

Advancing Patient Safety in Airway Management

Author: Michael F. Aziz, M.D. Anesthesiology 3 2018, Vol.128, 434-436. TRACHEAL intubation is a critical procedure that unites anesthesiologists as the definitive experts in the field of medicine. Not surprisingly, difficult airway management is the primary patient safety concern among anesthesiologists.1  Decades ago, the introduction of pulse oximetry and end-tidal CO2 were associated with a reduction in respiratory-related […]
