Determine mid-term postoperative outcomes among coronavirus disease 2019 (COVID-19)-positive (+) patients compared with those who never tested positive before surgery. ⋯ This is the first report of mid-term outcomes among COVID-19 patients undergoing surgery. COVID-19 is associated with decreased overall and complication-free survival primarily in the early postoperative period, delaying surgery by 5 weeks or more reduces risk of complications. Case urgency has a multiplicative effect on short-term and long-term risk of postoperative mortality and complications.

ReviewPulse wave analysis: basic concepts and clinical application in intensive care medicine.
The measurement of cardiac output ( CO ) is important in patients with circulatory shock. Pulse wave analysis (PWA) estimates CO continuously and in real-time using the mathematical analysis of the arterial pressure waveform. We describe different PWA methods and provide a framework for CO monitoring using PWA in critically ill patients. ⋯ Noninvasive PWA methods are generally not recommended in critically ill patients (who have arterial catheters anyway). PWA systems can be used to continuously track stroke volume and CO in real-time during tests of fluid responsiveness or during therapeutic interventions. During fluid challenges, continuous CO monitoring is important because - if CO decreases - a fluid challenge can be stopped early to avoid further unnecessary fluid administration. PWA externally calibrated to indicator dilution methods can be used - in addition to echocardiography - to diagnose the type of shock.

Compare adverse outcomes up to 5 years after sleeve gastrectomy and gastric bypass in patients with Medicaid. ⋯ Among patients with Medicaid undergoing bariatric surgery, sleeve gastrectomy was associated with a lower risk of mortality, complications, hospitalization, ED use, and reoperations, but a higher risk of revision compared with gastric bypass. Although the difference between sleeve and bypass was generally similar among White, Black, and Hispanic patients, the magnitude of this difference was smaller among Black patients for ED use and Hispanic patients for reoperation.

Transnasal Videoendoscopy for Preoperative Airway Risk Stratification: Development and Validation of a Multivariable Risk Prediction Model.
Transnasal flexible videoendoscopy (TVE) of the larynx is a standard of care for the detection and staging of pharyngolaryngeal lesions in otorhinolaryngology. Patients frequently present with existing TVE examinations before anesthesia. Although these patients are considered high risk, the diagnostic value of TVE for airway risk stratification is currently unknown. How can captured images or videos be used for anesthesia planning, and which lesions are most concerning? This study aimed to develop and validate a multivariable risk prediction model for difficult airway management based on TVE findings and to determine whether the discrimination of the Mallampati score can be improved by adding this new TVE model. ⋯ Stored images and videos from TVE examinations can be reused for the purpose of predicting risk associated with airway management. Vestibular fold, supraglottic, and arytenoid lesions are most concerning, especially if they are accompanied by secretion retention or restrict the glottic view. Our data indicate that the TVE model improves discrimination of the Mallampati score and might, therefore, be a useful addition to traditional bedside airway risk examinations.

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.
