I-gel vs Ambu AuraGain in Laparoscopic Gynecological Surgery

Status Enrolling by invitation

Clinical Trial Summary

To compare the effects of i-gel and Ambu AuraGain on ventilation parameters and surgical view during Trendelenburg position laparoscopic gynecological surgery in cases administered positive pressure ventilation without the use of neuromuscular agents.

Clinical Trial Description

Prospective, multicenter, randomized and double-blind study, aged from 18 to 65 years undergoing elective laparoscopic gynecological surgery. The patients are randomly assigned to 2 groups: Group i-gel Group Ambu AuraGain Procedure: The investigation protocol contains the following sections: 1. Induction of anaesthesia. For preoperative sedation 0.02 mg/kg midazolam IV will be administered. 2 minutes of 0.2 µ/kg/min remifentanil and 6 mg kg st-1 propofol infusion, IV 1-2 mg kg-1 propofol . No muscle relaxant will be used for insertion of the airway device. 2. Bispectral index values will be held between 40-60.Bispectral index values will be within this interval by increasing or decreasing propofol infusion by 1 mg/kg after additional bolus dose of propofol (1 mg/kg). 3. Insertion of the airway device. The size of the airway device used is based on the manufacturers' recommendations. 4. Anesthesia maintenance will be ensured by 50% O2/air with 0.1-0.4 µ kg/min-1 remifentanil and 4-10 mg/kg/hr propofol IV infusion 5. Functionality of the gastric drainage channel of the airway device 6. Measurement of airway seal pressure (oropharyngeal leak pressure (OLP): at baseline, and at 2 minutes after airway device insertion (T1), 10 minutes after insufflation (T2), before desufflation (T3), before removal of airway device (T4). The maximum pressure allowed is 40 cm H2O. 7. Ventilatory mechanics and parameters and hemodynamic parameters are measured at baseline, and at T1, T2, T3 and T4. 8. Perioperative complications: Cough, vomiting, laryngeal spasm, laryngeal Stridor, airway intervention requirements, hypoxia (SpO2 < 92%) 9. Removal of the airway device: Presence of blood - 3 level grading (1:no blood; 2: trace amounts of blood; 3: clear amounts of blood). Complications: sore throat ( VAS:10-point scale), dysphonia (yes/no), dysphagia (yes/no). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
