Extracorporeal Membrane Oxygenation with Right Ventricular Assist Device for COVID-19 ARDS.

Background: Right ventricular failure is an underrecognized consequence of COVID-19 pneumonia. Those with severe disease are treated with extracorporeal membrane oxygenation (ECMO) but with poor outcomes. Concomitant right ventricular assist device (RVAD) may be beneficial.

A comparison between the Supreme laryngeal mask airway and the laryngeal tube suction during spontaneous ventilation: A randomized prospective study.

Background And Aims: The Supreme laryngeal mask airway (SLMA) and the laryngeal tube suction-disposable (LTS-D), both second-generation supraglottic airway devices, have a record of efficiency when used for airway management in mechanically ventilated patients, during general anesthesia. There is no published data comparing these two devices in patients breathing spontaneously during general anesthesia.

Material And Methods: Eighty patients with normal airways undergoing elective general anesthesia with spontaneous ventilation were randomized to airway management with a SLMA or LTS-D.

The prediction of difficult intubation in obese patients using mirror indirect laryngoscopy: A prospective pilot study.

Background: The incidence of difficult laryngoscopy and intubation in obese patients is higher than in the general population. Classical predictors of difficult laryngoscopy and intubation have been shown to be unreliable. We prospectively evaluated indirect mirror laryngoscopy as a predictor of difficult laryngoscopy in obese patients.

Use of a third-generation perfluorocarbon for preservation of rat DCD liver grafts.

Background: Cold storage in any of the commonly used preservation solutions is not always adequate for donation after cardiac death (DCD) liver grafts due to prolonged warm ischemic time. In this study, we used a third-generation perfluorocarbon (PFC), Oxycyte, for DCD liver graft preservation in a rat model.

Materials And Methods: Twenty-eight rats (14 in each group) were used.

Transesophageal echocardiographic and oxymetric evidence of intraoperative reversal of flow through a patent foramen ovale during an off-pump coronary artery bypass grafting.

Mechanical stabilization of target coronary arteries in the beating heart has facilitated the practice of "off-pump" coronary artery bypass grafting. Exposing the target coronary artery for stabilization involves maneuvers that frequently cause hemodynamic alterations including decreased cardiac output and increased pulmonary artery and/or central venous pressures (CVP). The presence of a patent foramen ovale (PFO) in the setting of increased CVP may produce a right-to-left shunt through the PFO.

Comparison of arterial systolic pressure variation with other clinical parameters to predict the response to fluid challenges during cardiac surgery.

Prophylactic optimization of stroke volume during surgery has been thought by some to reduce complications following surgery. Mechanical ventilation has been shown to induce variations in systolic systemic arterial blood pressure. Measuring such variations in systolic pressure (SPV) might serve as an attractive method for guiding fluid therapy intraoperatively.

Central neuraxial analgesia in cardiac surgery.

An ideal anesthetic for cardiac surgery should provide intraoperative cardiovascular stability and a stable and pain-free recovery. High-dose narcotics, whether given as an initial bolus or by the continuous infusion method, certainly have brought current practice closer to this ideal. Central neuraxial analgesia is an alternative to high-dose narcotics, but its use has long been an issue of debate and concern in cardiac surgery.
