Short time effects of compliance guided flow-controlled ventilation versus standard of care pressure-controlled ventilation - a prospective porcine trial.
Flow-controlled ventilation (FCV) represents a novel ventilation method, which guarantees a continuous gas flow during inspiration and expiration. Long term comparison to volume- and pressure-controlled ventilation (PCV) after five- and ten hours have shown improved gas exchange parameters and lung tissue aeration. Aim of this porcine trial was to compare gas exchange parameters and lung tissue aeration in short time application of FCV compared to PCV to determine effects which will most probably pertain in short lasting procedures under general anesthesia. ⋯ In this short-term ventilation comparison FCV improved gas exchange parameters without differences in lung tissue aeration compared to PCV.

To estimate the incidence of unwanted spontaneous responsiveness and burst suppression (BSupp) in patients undergoing state entropy (SE) and surgical pleth index (SPI)-guided total intravenous anesthesia (TIVA) with target-controlled infusion (TCI). ⋯ The SE-SPI-guided TIVA-TCI did not prevent unwanted spontaneous responsiveness and BSupp. CeP RoR may be used as a proxy for anesthetic sensitivity.

Neuraxial Use Among Total Knee and Hip Arthroplasty Patients With Multiple Sclerosis or Myasthenia Gravis.
Surgical patients with preexisting neurological diseases create greater challenges to perioperative management, and choice of anesthetic is often complicated. We investigated neuraxial anesthesia use in total knee and hip arthroplasty (TKA/THA) recipients with multiple sclerosis or myasthenia gravis compared to the general population. ⋯ Neuraxial anesthesia use was lower in surgical patients with multiple sclerosis compared to the general population but no different in those with myasthenia gravis. Neuraxial use was associated with lower odds of prolonged length of stay.

Racial/Ethnic Variability in Use of General Anesthesia for Pediatric Magnetic Resonance Imaging.
Children increasingly undergo diagnostic imaging procedures, sometimes with general anesthesia (GA). It is unknown whether the use of GA differs by race/ethnicity among children undergoing magnetic resonance imaging (MRI) scans. ⋯ Asian, Black, and Hispanic children of some ages were more likely to receive GA during MRI scans than White children in the same age group. Future research is warranted to delineate whether this phenomenon signifies disparate care for children based on their race/ethnicity.

Deep sedation without tracheal intubation (monitored anaesthesia care) and general anaesthesia with tracheal intubation are commonly used anaesthesia techniques for endoscopic retrograde cholangiopancreatography (ERCP). There are distinct pathophysiological differences between monitored anaesthesia care and general anaesthesia that need to be considered depending on the nature and severity of the patient's underlying disease, comorbidities, and procedural risks. An international group of expert anaesthesiologists and gastroenterologists created clinically relevant questions regarding the merits and risks of monitored anaesthesia care vs general anaesthesia in specific clinical scenarios for planning optimal anaesthetic approaches for ERCP. ⋯ Patient age and ASA physical status were not considered to be factors for choosing between monitored anaesthesia care and general anaesthesia. Monitored anaesthesia care is the favoured anaesthesia plan for ERCP. An individual risk-benefit analysis that takes into account provider and institutional experience, patient comorbidities, and procedural risks is also needed.
