| Abstract Introduction: The reusable Laryngeal tube "LT-R" and disposable Laryngeal tube "LTD" are two relatively new devices for maintaining the airway during controlled ventilation under general ansthesia. The present inventilation was ained to compare the performance of the LT-R and LT-D in a randomized controlled study. Materials & Methods: One huandred ASA (I-II-III) patientsm aged 15-65 years, undergoing elective minor surgeries were randomized to receive either a LTR (N= 50) or LTD (N=50) for airway management. After induction of general anesthedia, devices were inserted, correct placement was verified, and airway leak pressure was measured. Time of insertion, quality of air way seal, fiberoptic view and post- operative pharyngeal morbidity was examined. Finding: The first and second time success rates were comparable for both groups (90 vs 96% and 96 vs 98% in LT-D and LTR groups, respectively). The air wary of two patients in the first group could not be maintained with LT-D. The time until delivery of first tidal volume for LT-D and LT-R was 28.48 ± 2.1 sec and 23±2.1, while fixation and manipulation time was 50±2.2 and 47±2.5 respectively. Afterward, the patients were questioned for any post-operative pharyngeal complications. No significant differences were seen between the two groups, regarding possible after- effects. Conclusion: It is concluded that both The devices seem to provide a secure airway similar clinical efficacy. Furthermore, it is easy to insert them all the same. |
