Brief Summary

Prediction of difficult preoperative intubation in obese patients and completion of preparations for difficult intubation both reduce the risk of repeated intubation and prevent complications. In this study, the investigators aimed to evaluate whether anthropometric measurements are superior in defining difficult preoperative airways.

Conditions

Intubation; Difficult or Failed; Obesity; Anesthesia

Outcome Measures

Primary Outcomes (1)

• Suprasternal Adipose Tissue Thickness

  It is predicted that it may indicate difficult intubation.

  within 10 minutes before going into surgery

Secondary Outcomes (13)

• Abdominal circumference

  within 10 minutes before going into surgery

• Waist circumference

  within 10 minutes before going into surgery

• Arm circumference

  within 10 minutes before going into surgery

• Distance between incisions

  within 10 minutes before going into surgery

• Thyromental distance measurement

  within 10 minutes before going into surgery

Study Arms (2)

Difficult Intubation

Abdominal circumference, waist circumference, arm circumference, distance between incisions,TMD and SMD measurements, Mallampati test, Wilson score, and suprasternal subcutaneous adipose tissue thickness were measured and recorded. ECG, SBP and DBP, and SpO2 monitoring were performed. Pre-oxygenation was performed using a 100% oxygen face mask for 3 min before the induction of anesthesia. Induction of anesthesia was achieved with IV 1 mg/kg lidocaine, 0.125 mcgr/kg fentanyl, 2 mg/kg propofol, and 0.6 mg/kg rocuronium bromide. After 2 min of adequate muscle relaxation, the patient was intubated with an endotracheal tube of appropriate diameter. Cormack-Lehane score was evaluated during laryngoscopy. Patients with more than 3 intubation attempts by an experienced anesthesiologist were considered difficult to intubate. In maintenance, 0.1 mcg/kg/h remifentanil was administered in sevoflurane O2-air mixture. Age, sex, body weight,BMI, and ASA scores were recorded.

Not Difficult Intubation

Abdominal circumference, waist circumference, arm circumference, distance between incisions,TMD and SMD measurements, Mallampati test, Wilson score, and suprasternal subcutaneous adipose tissue thickness were measured and recorded.
