Abstract: 

Background: The reusable laryngeal tube "LT-RD and disposable laryngeal tube "LT-D" are two relatively new devices introduced for maintaining the airway during controlled ventilation under general ansthesia. Materials and Methods: The present investigation compared the performance of the LT-R and LT-D randomized controlled study 100 ASA I, II, III patients, aged 15-65 years undergoing elective minor surgery received either a LT-R (n=50) or LT-D (n=50) for airway management. After induction of general anesthesia, devices were inserted, correct placement was verified, and airway leak pressure was measured. Time of insertion, quality of airway seal, fiberoptic view and post-operative pharyngeal morbidity was examined.
Results: First time and second time success rates were comparable for both groups (90 vs 96% and 96 vs 98% in LT-D and LT-R groups, respectively). The airway of two patients in first group could not be maintained with LT-D. Time until delivery of first tidal volume for LT-D and LTR was 28.48
±2.1 sec and 23±2.1, fixation and manipulation time was 50±2.2 and 47±2.5 respectively.
Conclusion: Patients were questioned for a variety of post-operative pharyngeal morbidities. Significant differences were seen between these groups in the morbidities. Both devices seem to provide a secure airway, work similar in clinical utility, and are easy to insert.
