A prospective study to evaluate and compare laryngeal mask airway ProSeal and i-gel airway in the prone position

Abstract

Background:Prone position is commonly used to provide surgical access to a variety of surgeries. In view of the advantages of induction of anesthesia in the prone position, we conducted a randomized study to evaluate and compare ProSeal laryngeal mask airway (LMA) and i-gel in the prone position.Materials and Methods:Totally, 40 patients of either sex as per American Society of Anesthesiologists physical status I or II, between 16 and 60 years of age, scheduled to undergo surgery in prone position were included in the study. After the patients positioned themselves prone on the operating table, anesthesia was induced by the standard technique. LMA ProSeal was used as an airway conduit in group 1 while i-gel was used in group 2. At the end of surgery, the airway device was removed in the same position.Results:Insertion of airway device was successful in first attempt in 16, and 17 cases in ProSeal laryngeal mask airway (PLMA) and i-gel groups, respectively. A second attempt was required to secure the airway in 4 and 3 patients in PLMA and i-gel groups, respectively. The mean insertion time was 21.8 ± 2.70 s for group 1 and 13.1 ± 2.24 s for group 2, the difference being statistically significant (P < 0.05). The mean seal pressure in group 1 was 36 ± 6.22 cm H2 O and in group 2 was 25.4 ± 3.21 cm H2 O. The difference was statistically significant (P < 0.05). 13 patients in group 1 had fiberoptic bronchoscopy (FOB) grade 1 while it was 6 for group 2. The remaining patients in both groups had FOB grade 2.Conclusion:Insertion of supraglottic airways and conduct of anesthesia with them is feasible in the prone position. The PLMA has a better seal while insertion is easier with i-gel.

Evaluation of performance of Streamlined Liner of the Pharynx Airway™, Laryngeal Mask Airway-ProSeal and endotracheal tube in prone position: A prospective, randomised study

“…The mean leak pressure recorded in Group-P in prone [ Table 3 ] are slightly less than that reported in the previous studies (31–36 cmH 2 O). [ 15 16 17 ] The mean leak pressure recorded in Group-S in supine position was similar to that reported earlier (23.4–30 cmH 2 O). [ 7 18 19 20 21 ]…”

“…Only a few studies have evaluated PLMA during prone anaesthesia[ 15 16 17 26 ] and there are no prospective studies on SLIPA™. López et al .…”

Supraglottic airway devices: a powerful strategy in airway management

“…Another clinical trial examining the performance of the pLMA and I-gel airways in the prone position similarly confirmed this finding. Insertion of the SAD was feasible in the prone position [130]. pLMA demonstrated superior closure, whereas I-gel demonstrated an easier insertion process.…”

A Novel and Modified Technique in the Prone Position for Radiotherapy Processes in Children

“…The i-gel is often used during minor surgeries with the patient in the supine position. The i-gel has been used in the prone position by various authors in elective surgeries ( 2 , 3 ). However, with its’ thick airway tube, occasionally, achieving the airway can be difficult because of obstruction in the prone position.…”
