What this study is about

This study aims to evaluate whether the Left Head Rotation (LeHeR) maneuver improves visualization of the vocal cords during video laryngoscopy in obese adult patients undergoing general anesthesia. Obesity is associated with increased difficulty in airway management due to excess upper airway soft tissue and altered anatomy, which may impair visualization during intubation. In this prospective observational study, 50 adult patients with a body mass index (BMI) ≥30 kg/m² will undergo video laryngoscopy using a C-MAC D-blade. The glottic view will be assessed using the Percentage of Glottic Opening (POGO) score in the standard sniffing position and after rotating the head 45 degrees to the left (LeHeR maneuver). A difference in POGO score between the two positions will be analyzed. Secondary outcomes include ease of intubation, number of attempts, time to successful intubation, and occurrence of complications such as desaturation or airway trauma. The study is expected to determine whether the LeHeR maneuver is a simple and effective technique to improve airway visualization in obese patients.

A promising-looking record is not the same as confirmed eligibility. The study team must review the full criteria and current recruitment status.

Primary outcomes

Change in Percentage of Glottic Opening (POGO) Score between Sniffing Position and Left Head RotationBaseline during induction of anaesthesia at the time of video laryngoscopy on Day 1 (single intra-operative assessment)

The Percentage of Glottic Opening (POGO) score will be assessed during video laryngoscopy in the sniffing position and after 45-degree left head rotation (LeHeR maneuver). The difference in POGO score between the two positions will be recorded for each participant.
