简要总结
The aim of the study is to compare the performance of two supraglottic airway devices (SGA), the new Ambu AuraGain and the LMA Supreme, in sixty female patients undergoing gynaecologic laparoscopy in the trendelemburg position.
Primary outcome is the airway seal pressure. Secondary outcomes are ease of insertion, quality of ventilation, endoscopic view of the glottis, gastric tube passage and complications.
详细描述
The patients are randomly assigned to 2 groups:
- Group 1: Ambu AuraGain.
- Group 2: LMA Supreme, Teleflex
Procedure:
The investigation protocol contains the following sections:
- Induction of anaesthesia. Intravenous infusion of remifentanil and propofol targeting the effect site (2-4 ng/ml and 4-6 µg/ml respectively). No muscle relaxant will be used for insertion of the SGA. Rocuronium 0.2 mg/Kg will be administered before initiation of pneumoperitoneum.
- Insertion of the SGAs. The size of the SGA device used is based on the manufacturers' recommendations. All devices are deflated a lubricated prior to use. Once inserted, the cuff is be inflated with a manometer up to 60 cm H20 Position of the device is adjusted if needed. Data recorded: size of SGA, time an number of attempts.
- Fibreoptic evaluation of the SGAs anatomical position: complete view of the vocal cords (I), epiglottis visible inside, but not causing obstruction (II), epiglottis visible and obstructing the glottic inlet (III), or glottic structures not identified (IV).
- Functionality of the gastric drainage channel of the SGAs: passage of a 16 G size tube.
- Measurement of airway seal pressure (oropharyngeal leak pressure (OLP): at baseline, and at 15, 30 and 60 minutes. The maximum pressure allowed is 40 cm H2O.
- Ventilatory mechanics and parameters are measured at baseline, and at 15, 30 and 60 minutes.
