Evaluation of I-Gel™ versus classic LMA™ for airway management by paramedics and medical students: A manikin study

Background and Aim Airway management is a lifesaving skill which all health-care workers should possess. Currently, most of the resuscitation councils recommend supraglottic airway devices as the technique of choice for airway management during cardiopulmonary resuscitation by health-care providers without expertise in tracheal intubation. This is because of its high first-pass success rate and easy to acquire and retain skill even by novices. Materials and Methods The present study was planned to compare the efficacy of two commonly available supraglottic airway devices, classic LMA (cLMA) and I-gel in securing airway in adult manikin by inexperienced persons (58 paramedics and 46 medical students), after a brief training. Our primary aim was to determine the first attempt success rate, and other parameters studied were the time and ease of insertion, overall success rate, and preference for device. Results The first-attempt success rate of I-gel was higher in both groups of participants (74% in students and 69% in paramedicals) compared to that of cLMA (70% in l students and 53% in paramedics) although the overall success was the same. Majority of participants could secure airway quickly and easily by I-gel than by cLMA. More than 90% of participants preferred I-gel over cLMA. Conclusion This study shows that inexperienced persons could learn to place the I-Gel and cLMA successfully in the manikin after a brief training in manikin. The first-attempt success rate and insertion of I-gel was easier and faster than that of cLMA by both groups of participants and most participants preferred I-gel due to ease of handling.
