I-Gel versus Laryngeal Suction Tube- II: Comparison of Two Supraglottic Airway Devices in Elective Surgical Procedures
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 12
Abstract
Context: Supraglottic airway devices have been established in clinical anesthesia practice and have been previously shown to be safe and efficient. Two new supraglottic airway devices, I-gel and laryngeal suction tube-II offer potential benefits when used in elective surgical procedures. Aims: The objective of this study was to compare I-Gel with LTS II to determine device performance during general anesthesia and controlled ventilation, by comparing the ease of insertion, number, and duration of insertion attempts and complications among the two devices. Settings and Design: This study was conducted as randomized controlled study in a teaching hospital. Subjects and Methods: Sixty patients undergoing elective surgical procedures of 60-90 minutes duration were randomly divided in two groups of thirty each, I-gel (Group I) or LTS II (Group L) group. Anesthesia was induced with standard drugs and the supraglottic airway device was inserted. The following parameters were noted: hemodynamic changes ease and time required for insertion, successful placement of device, correct placement of nasogastric tube and post-operative morbidity (dysphagia, sore throat) Statistical Analysis Used: Descriptive analyses were expressed as a mean ± standard deviation and proportions or percentage as appropriate. Data are presented as mean ± standard deviation and proportions or percentage as appropriate. Data comparison was performed by Student's t-test (continuous variables) and chi-square test (categorical variables). A significant difference was assumed with p-value less than 0.05. Results: I-gel was significantly easier to insert with success rate of 100% on first attempt (P< 0.010) as compared to 93.33% for the LTS II. The airway of two patients could not be managed with LTS II after two attempts, and were thus intubated with endotracheal tube. More patients complained of sore throat with LTS II than I-gel (13.33% vs10.00%) at 6hrs post-extubation. Conclusion I-Gel is a supraglottic device which is easier to insert with increased likelihood of successful insertion on first attempt and less traumatic with lower incidence of sore throat. Hence I-Gel can be a good alternative to LTS II, though both devices provide a secure airway.
