The comparison of ProSeal and I-gel laryngeal mask airways in anesthetized adult patients under controlled ventilation

Abstract

Objectives:To compare the insertion time, ease of device insertion, ease of gastric tube insertion, airway leakage pressure, and complications between the laryngeal mask airway (LMA) ProSeal (P-LMA) and I-gel (I-gel) groups.Methods:Eighty patients with age range 18-65 years who underwent elective surgery were included in the study. The study took place in the operation rooms of Haydarpaşa Numune Hospital, Istanbul, Turkey from November 2013 to April 2014. Patients were equally randomized into 2 groups; the I-gel group, and the P-LMA group. In both groups, the same specialist inserted the supraglottic airway devices. The insertion time of the devices, difficulty during insertion, difficulty during gastric tube insertion, coverage of airway pressure, and complications were recorded.Results:The mean insertion time in the I-gel group was significantly lower than that of the P-LMA group (I-gel: 8±3; P-LMA: 13±5 s). The insertion success rate was higher in the I-gel group (100%, first attempt) than in the P-LMA group (82.5%, first attempt). The gastric tube placement success rate was higher in the I-gel group (92.5%, first attempt) than in the P-LMA group (72.5%, first attempt). The airway leakage pressures were similar.Conclusion:Insertion was easier, insertion time was lower, and nasogastric tube insertion success was higher with the I-gel application, and is, therefore, the preferred LMA.

Comparison of I-gel for general anesthesia in obese and nonobese patients

“…Insertion time (time elapsed between anesthesiologist first picking up the i-gel and correct i-gel placement), number of insertion attempts and ease of insertion (on following scale:[ 1 ] successful placement in the first attempt;[ 2 ] placement in the first attempt but with resistance;[ 3 ] placement required two attempts; and[ 4 ] failed placement) were recorded. OLP was measured by closing the adjustable pressure limiting valve of the circle breathing system and noting the pressure at which leak developed (detected by a stethoscope placed just lateral to thyroid cartilage) at fresh gas flow of 3 L/min.…”

“…I-gel is well known for its simplicity, ease of insertion and low complication rate; and has been studied by several authors. [ 1 2 3 4 ] It has high oropharyngeal leak pressure (OLP) and a gastric channel which reduces the risk of reflux and regurgitation. I-gel has been successfully inserted in 100% patients by inexperienced users.…”

Comparison of I-Gel and Proseal Laryngeal Mask Airway for Airway Management in Adult Patients Undergoing Elective Surgeries in General Anaesthesia

“…Based on previous similar study 7 done, the expected proportion of success in first attempt of insertion of device was determined (P0= 0.825 and P1= 0.99). The sample size was calculated with -error of 0.05 and power of study 80%.…”

Comparing performance of ProSeal laryngeal mask airway and I-gel in anesthetized adult patients

“…We have read Zhang et al’s comments on our publication 1 with great interest. We would like to thank them for their interest in our study, their recommendations, and the opportunity they have given us to describe and discuss certain details we refrained from including in the article, out of concern that by doing so, it would have excessively increased the article’s length.…”

“…With great interest, we read the recent article by Ekinci et al 1 comparing the performance of ProSeal laryngeal mask airway (PLMA) and I-gel in anesthetized adult patients. They showed that insertion was easier, insertion time was shorter, success rate of nasogastric tube insertion was higher, and complications were fewer with the I-gel compared to the PLMA.…”
