About this study

Tree different head and neck positions will compare for glottic visualization and intubation success rates in obese patients (BMI> 30 kg / m2) who required endotracheal intubation for general anesthesia between 18-65 years of age.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Being 18-65 aged
  • Being obese
  • Undergoing surgery under general anesthesia

Exclusion criteria

  • Having difficult airway
  • Being American Society of Anesthesiologist (ASA) 4 physical status
  • Undergoing emergency surgery

Treatment and study plan

McGrath MAC videolaryngoscope

Device

Patient's laryngoscopy will be done using McGrath Mac video laryngoscope

Primary outcomes

  1. Glottic view

    Time frame: During laryngoscopy

    the percentage of glottic opening (POGO) and cormack-lehane scores will be used to rate of the glottic view

  2. Intubation Success

    Time frame: During intubation

    Intubation attempt number will be recorded

Secondary outcomes

  1. Intubation difficulty

    Time frame: During Laryngoscopy

    Intubation Difficulty Scale(IDS) score will be recorded.The IDS score is derived from seven variables. N1 represents the number of additional intubation attempts, N2 represents the number of additional operators, N3 is the number of alternative intubation techniques used; N4 represents the laryngoscopic view, N5 represents the lifting force applied during laryngoscopy, N6 represents the necessity to apply external laryngeal pressure to optimize glottic exposure, N7 represents the mobility of vocal cord. The IDS score is the sum of all variables and ranges from zero to infinity. A score of 0 indicates an easy tracheal intubation. Intubation is considered difficult if the score is greater than 5.

  2. Intubation time

    Time frame: During Intubation

    The duration of the endotracheal tube placement will be recorded
