Videolaryngoscope vs VideoLMA for Endotracheal Intubation in RIRS

This study is a prospective, randomized, parallel-group clinical trial comparing videolaryngoscope and videoLMA for endotracheal intubation in adult patients undergoing surgery. Patients will be randomly assigned into two groups. The primary outcome is intubation time. Secondary outcomes include first attempt success rate, number of attempts, oxygen desaturation, hemodynamic changes, and postoperative complications.

About this study

Airway management is a critical component of anesthesia practice. Videolaryngoscopes and videoLMA devices are widely used tools for endotracheal intubation. While videolaryngoscopes provide improved visualization of the glottis, videoLMA devices can facilitate both airway management and guided intubation.

In this prospective randomized study, 100 patients will be assigned to either videolaryngoscope or videoLMA groups. Standard anesthesia induction will be applied. Intubation time, success rates, hemodynamic responses, and complications will be recorded and analyzed.

Device

Patients undergoing endotracheal intubation using videolaryngoscope

VideoLMA

Device

Patients undergoing endotracheal intubation using videoLMA

Primary outcomes

  1. Intubation Time

    Time frame: From insertion of the airway device to confirmation of endotracheal tube placement (during anesthesia induction, within approximately 0-5 minutes)

    Time from insertion of the airway device into the patient's mouth until successful placement of the endotracheal tube, confirmed by continuous capnography.

Secondary outcomes

  1. First Attempt Success

    Time frame: During first intubation attempt (within 0-2 minutes)

    Successful placement of the endotracheal tube on the first attempt without the need for additional airway maneuvers.

  2. Number of Attempts

    Time frame: During intubation procedure (within approximately 0-10 minutes

    Total number of attempts required to achieve successful endotracheal intubation.

  3. Oxygen Desaturation

    Time frame: During intubation procedure (from induction until successful intubation, approximately 0-10 minutes)

    Occurrence of oxygen desaturation defined as peripheral oxygen saturation (SpO₂) below 92% during the intubation procedure.

  4. Heart rate

    Time frame: At baseline (pre-induction), immediately after intubation, and at 1, 3, and 5 minutes post-intubation

    changes in heart rate measured at predefined time points

  5. Postoperative Sore Throat

    Time frame: At postoperative 1 hour and 2 hours

    Presence of sore throat assessed using a standardized patient-reported scale.

  6. Hoarseness

    Time frame: At postoperative 1 hour and 2 hours

    Presence of voice changes (hoarseness) assessed based on patient self-report.

  7. Complications

    Time frame: During intubation and intraoperative period (approximately 0-60 minutes)

    Occurrence of airway-related complications including mucosal injury, dental trauma, or esophageal intubation observed during the procedure.

  8. mean arterial pressure

    Time frame: baseline, post intubation,1,3,5 min

    changes in mean arterial pressure measured at predefined time points
