"Effects of Conventional and Video Laryngoscopy Methods on VIDIAC Scores and Hemodynamic Stability in Obese Patients: Comparison of Storz C-MAC3, Scoper MAC-3 and Macintosh"
This study aims to evaluate how intubation performed with two different brands of videolaryngoscope and the Macintosh laryngoscope during surgeries in obese patients requiring general anesthesia affects the VIDIAC score, hemodynamic response, and early postoperative complications. Complications such as sore throat, hoarseness, nausea, and vomiting will be recorded in the recovery room prior to discharge.
Success in airway management is critical for the safety of anesthesia practices. Unsuccessful airway management is a leading cause of anesthesia-related morbidity-including airway trauma, dental injury, pulmonary aspiration, unplanned tracheostomy, hypoxic brain injury, and cardiopulmonary arrest-and mortality.
Unsuccessful airway management accounts for approximately 30-40% of anesthesia-related deaths. In a review of closed insurance claims against anesthesiologists, 17% were related to difficult or impossible intubation without documented preoperative airway assessment.
Video laryngoscopes are technological tools used to visualize airway structures and facilitate endotracheal intubation, particularly in patients with anticipated difficult airways.
Obesity is a metabolic disorder characterized by excessive fat accumulation and is associated with both physical and psychological complications. It is an independent risk factor for difficult airway and increases the risk of anesthesia-related complications. Obesity is also linked to restrictive lung disease due to increased intra-abdominal pressure and decreased thoracic compliance. The resulting reductions in static and dynamic lung volumes lead to rapid desaturation during apnea or hypoventilation, primarily due to reduced functional residual capacity and expiratory reserve volume.
In this prospective observational study, the investigators aim to perform a comparative analysis of VIDIAC scores, hemodynamic responses (heart rate, systolic and diastolic blood pressure, mean arterial pressure), and early postoperative complications following laryngoscopy performed with Storz C-MAC videolaryngoscope, Scoper videolaryngoscope, and Macintosh laryngoscope in obese patients undergoing elective surgery under general anesthesia.
