LMA® Gastro Airway Versus Gastro-Laryngeal Tube in Endoscopic Retrograde Cholangiopancreatography

Airway Complication of Anesthesia Clinical Trial

Official title: Comparison of LMA® Gastro Airway and Gastro-Laryngeal Tube in Endoscopic Retrograde Cholangiopancreatography: a Prospective Randomized Observational Trial

Status Completed

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.

Clinical Trial 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. ;
