Influence of supraglottic airway device placement on cerebral hemodynamics.

Background: Supraglottic airway devices (SGDs) are of current use in anesthesia practice and in emergency conditions. It has been suggested that cerebral blood flow (CBF) can decrease after SGD insertion or cuff inflation; however, it is uncertain if this reduction is caused by the SGD or the anesthetic drugs utilized for the anesthetic procedure. During minor surgery we separated CBF measurements by an adequate time interval in order to measure the distinctive changes in cerebral hemodynamics associated with anesthesia induction, SGD insertion and cuff inflation.

Near-zero difficult tracheal intubation and tracheal intubation failure rate with the "Besta Airway Algorithm" and "Glidescope® in morbidly obese" (GLOBE).

Background: Unpredicted Difficult Tracheal Intubation (DTI) with Macintosh occurs frequently in obese patients. We investigated the incidence of DTI using an algorithm based on preoperative assessment with the El-Ganzouri Risk Index (EGRI) and Glidescope® routine use.

Methods: We prospectively enrolled morbidly obese patients undergoing abdominal surgery.
