Clinical Trial Summary

Comparison of second generation supraglottic airway devices about anesthesiologist, endoscopist and patient, which used for gastrointestinal procedures. The investigators believe that the endoscope will be easier to reach by the part of GLT extending to the esophagus, but the structural stiffness of this part may damage the esophageal mucosa. On the other hand, since the endoscopic canal of the LMA® Gastro ends at the upper end of the esophagus, it may be more difficult to orient the endoscope to the esophagus, but it may be superior in terms of ventilation efficiency. Therefore these two device worth for comparing.


Description:

Supraglottic airway (SGA) devices are produced for avoiding endotracheal intubation for anesthesic interventions. Second generation SGA's like GLT and LMA® Gastro airway are using for endoscopic biliopancreatic procedures. Both of them have an airway canal and endoscopic canal. Although they can use for same reason, their designs are different. So, their airway securities, endoscopic manipulations and complications, would be different. This study planned as single blind. American Society of Anesthesiologists (ASA) Physical status 1-2 100 patients which will be take endoscopic retrograde cholangiopancreatography (ERCP) included. The study starts after randomization and ends after discharge from the recovery room. All patients will be monitorised for hemodynamic parameters. Depth of anesthesia will be provided by bispectral index (BIS) monitoring. After anesthesia induction SGA will placed by an experienced anesthesiologist. Bilateral chest movements and auscultation, capnogram graphy and oropharyngeal leak pressure test will be used for confirmation of placement. After procedure endoscopist will take pictures of esophagus and hypopharynx. After extubation and sufficient consciousness and breathing of patient, patients will be transferred to post-anaesthesia care unit (PACU). Vital parameters will continue to monitoring in PACU. Patients will be discharge as usual with an Aldrete score ≥ 9. Data will be collected during the procedure and in recovery room. Data will be stored in electronic database without mention to patient's name.

Outcome

Type Measure Description Time frame Safety issue
Primary Oropharyngeal leak pressure Oropharyngeal leak pressure is the airway pressure at which the circuit pressure stabilizes by closing the expiratory valve of the circle system at a constant gas flow of 3 L / min. Intra-operative; after device insertion
Primary Endoscopist satisfaction analysis: score Endoscopist will score from 0 (worst) to 10 (best) Immediately after the procedure
Primary Leakage rate percentages The leakage rate percentage is the calculation of the difference between the adjusted tidal volume and the exhaled tidal volume and then proportioning to the adjusted tidal volume. Intra-operative; after device insertion at first minute
Secondary Hypopharyngeal/Esophageal Mucosal status Number of patients with hyperemia, laceration (while extubating patient, endoscopist will take pictures of esophagus for if there is any mucosal damage). Esophageal and hypopharyngeal mucosal damage was determined in 5 grades by a visual mucosal damage scoring system [grade 1- normal mucosa, grade 2- mild hyperemia, grade 3-severe hyperemia, grade 4-bloody gross hyperemia, grade 5- laceration]. Within the first minute after the procedure is completed, while the duodenoscope is being removed while it passes through the esophagus and hypopharynx
Secondary Blood staining on the device Whether there is blood on the supraglottic airway device or not Immediately after removing the supraglottic airway device
Secondary Presence of sore throat Sore throat if present, was classified as mild, moderate or severe. One hour after extubation
