Use of New Supraglottic Airway Devices in Severely Obese Patients: A Feasibility Study

Phase 4
Withdrawn
Conditions
Obesity
Interventions
Device: IGEL
Device: King airway
Registration Number
NCT01124825
Lead Sponsor
University of Louisville
Brief Summary

The purpose of this study is to determine whether two new airway devices used during anesthesia called iGEL™ and KING-LTS-DTM work well and are safe in obese patients. They both work well in thin patients, but have not been tested in obese patients.

Inclusion Criteria
  • Scheduled for elective surgery with an estimated duration of 30 to 120 minutes
  • American Society of Anesthesiologists (ASA) status I-III
  • Aged 18 to 65 years.
  • Body mass index (BMI) ≥ 35 kg/m2
Exclusion Criteria
  • A history of difficult intubation;
  • Immobilized cervical spine;
  • Oxygen saturation less than 95% at room air;
  • A history of uncontrolled gastroesophageal reflux or hiatus hernia;
  • A history of ulcer surgery including vagotomy;
  • Previous gastric bypass surgery;
  • Diabetic gastroparesis;
  • Patients with known coagulation disorders (e.g. hemophilias, von Willebrand disease, factor V leiden diseases) or on systemic anticoagulation drugs (e.g. continuous heparin infusion); Patients with abnormal coagulation tests will be also excluded. However, asymptomatic patients will not be tested on any coagulation disorders.
  • Any pathologies of the mouth, pharynx or larynx, the access to the airway is restricted, or a difficult tracheal intubation is anticipated.
