Study Overview
Brief Summary
This is a prospective, observational study designed to evaluate airway management techniques used during elective surgery under general anesthesia. The study focuses on perioperative hemodynamic parameters and airway-related procedural characteristics.
Detailed Description
Study Design This is a single-center, prospective, observational study conducted at Akdeniz University Hospital after approval by the Institutional Ethics Committee (Approval No: 70904504/139). Written informed consent was obtained from all participants prior to enrollment.
Participants Adult patients scheduled for elective surgery under general anesthesia between March and June 2024 were screened for inclusion.
Exclusion Criteria Patients were excluded if they were under 18 years of age, pregnant, had known hypersensitivity to anesthetic agents, gastroesophageal reflux disease, or active upper respiratory tract infection.
Group Allocation and Airway Management
Due to the observational design of the study, randomization was not performed. Patients were allocated to groups according to the airway management technique selected by the attending anesthesiologist:

Arms & Interventions
Group 1: SaCoVLM™ Video Laryngeal Mask Group 2: Direct Laryngoscopy
Group 1: SaCoVLM™ Video Laryngeal Mask (VLM), "Intubation performed using SaCoVLM™ video laryngeal mask under general anesthesia."
Group 2: Direct Laryngoscopy (DL),: "Intubation performed using direct laryngoscopy under general anesthesia."
Outcomes
Primary Outcomes
Change in Mean Arterial Pressure During Intubation
Time Frame: Baseline (pre-induction) and 1 minute after endotracheal tube placement
Mean arterial pressure (MAP) measured non-invasively at baseline (before induction of anesthesia) and at 1 minute after successful endotracheal tube placement.
Secondary Outcomes
- First-Attempt Intubation Success(During airway instrumentation (peri-procedural) Unit of Measure Percentage (%))
- Heart Rate Response to Intubation(Baseline (pre-induction) and 1 minute after endotracheal tube placement Unit of Measure beats per minute)
- Oxygen Saturation During Airway Management(Baseline and during airway instrumentation Unit of Measure Percentage (%))
