Official title
Assessing Intraoperative Airway Changes and Their Regression to Baseline in Patients Undergoing Elective Surgical Procedures in the Prone and Trendelenburg Positions
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to track the intraoperative changes that occur in the airways of patients undergoing 1) laparoscopic surgeries in the Trendelenburg position, and 2) spinal surgeries in the prone position, as well as the regression of these changes postoperatively. These surgeries are known to cause edema and swelling of the soft tissues of the head and neck, temporarily worsening airway anatomy, but there is little data quantifying these changes, and no studies have investigated the time course required for the airway to return to its baseline after extubation. This would be important clinical information given that airway management is always a major concern perioperatively. The investigators will test hypotheses by evaluating patients' airways preoperatively, immediately post-extubation, and at regular intervals thereafter using the Modified Mallampati Score class (MMS), in which a patient's airway is scored from class 1 to 4 (in which 4 indicates the highest likelihood of a difficult intubation) based on the visibility of the soft palate, uvula, and faucial pillars inside the oral cavity.
