Performance of Easytube,Esophageal-Tracheal Combitube and Laryngeal Tube Suction : a Comparative Study

ABSTRACT

Background: The aim of study is to compare easytube, etc,and lts in terms of - difficulty of device insertion, time to achieve airway, insertion success rate, haemodynamic parameters following device insertion and frequency of adverse effects. Methods: This randomised single blind study was conducted on 90 patients of age 18-60 years, undergoing elective surgery requiring general anaesthesia. Patients were randomly allocated in three groups- Group ETC (n= 30), Group EzT (Esophageal Tracheal Combitube) (n=30). After preoxygenation, induction and muscle relaxation appropriate ETC, Easy Tube,LTS was inserted and all parameters were noted by an independent observer. For statistical analysis, Student t-test was employed to compare the means and Chi-square test was used for categorical variables. Results: The demographic profile of patients in all groups was similar. Amongst each group device was placed in single attempt in all patients . The mean time for effective placement of the device was longer in group EzT (49.13±7.49 ) compared to groupETC and LTS(48.76±7.15). Conclusion: The intraoperative ventilation was equally effective and safe with all three devices. The intubation response was similar in magnitude with all devices and more importantly it was transient, not interfering with intraoperative usage. We also conclude that placement of ETC and LTS is easier than Easytube.
