“…We routinely insert cLMA with the aid of muscle relaxants to reduce deep anesthesia-related side effects and possible injuries to patients, although we do not have clear evidence, which might be different from the clinical practice in other institute or country where muscle relaxants are not used for LMA insertion. Muscle relaxants may affect the difficulty level of LMA insertion [24], but it does not affect our conclusions because both groups of patients in our study received muscle relaxants before cLMA insertion. Our patients kept breathing spontaneously during surgery, so results may be less applicable to patients who are paralyzed by muscle relaxants.…”

“…After loss of consciousness, mask ventilation was performed using 3-5% sevoflurane in oxygen. 14 Cricoid pressure was applied at a standardized force of 30 N, 5 8 which sufficiently prevents regurgitation into the pharynx, even in patients with a full stomach undergoing Caesarean section. 15 An independent anaesthetist was trained to apply the force by practising on a weighing scale with a top board; within an error of 5%.…”

“…For example, Fujiwara et al reported that success rate in first attempt with i-gel was 100%, however, success rate in first attempt with LMA was 84%. 20 Similarly, Acharya et al reported that ease of insertion is higher in i-gel TM as compared LMA classic TM (p<0.05). 21 In the current study, among all patients in i-gel group, insertion time was found to be lower (9.5sec±0.7SD) as compared to patients in LMA group (10.67sec±1.6SD) (p=0.02).…”

Background: Upper airways collapse during anesthesia is a common issue faced by anesthetists. Air way maintenance is an essential component of general anesthesia. Laryngeal mask airway and Intersurgical-gel (i-gel) air way devices are new advances in general anesthesia. Present study aims to compare the ease of insertion and hemodynamic response of i-gel supraglottic and laryngeal mask airway (LMA). Material and Methods: A Randomized Clinical trial was conducted at the Department of Anesthesia, Shaikh Zayed Hospital, Lahore. Study duration was 6 months (June 2014- December 2014). A total of 60 patients were selected through non-probability consecutive sampling. Ethical approval was taken from ethical review board of Sheikh Zayed Hospital and informed written consents were taken from all the participants. Patients were randomly divided into two groups using lottery method. Group A was given laryngeal mask airway device while group B patients were provided with i-gel supraglottic device during anesthesia. Patients were compared for ease of insertion and hemodynamic parameters. Data was analyzed using SPSS version 24. Chi-square and t-test were applied and p-value ≤0.05 was considered statistically significant. Results: A total of 60 patients were included in study. Mean age of patients was 35.2±11.7 years in LMA group and 36.7±13 years in i-gel group. Group B had lower number of insertion attempts (p=0.01) and high insertion satisfaction (p=0.4) as compared to group A. However, process failure and bleeding rate was found to be slightly higher in group B (16% and 13% respectively) as compared to group A (p>0.05). Conclusion: i-gel supraglottic device is a successful alternative option in terms of ease of insertion and less hemodynamic response as compared to laryngeal mask airway during general anesthesia.

Muscle relaxant effects on insertion efficacy of the laryngeal mask ProSeal® in anesthetized patients: a prospective randomized controlled trial

Abstract: Muscle relaxation appears to facilitate ProSeal insertion efficacy by enabling higher successful insertion rates, higher sealing pressure, lower leakage volume, and lower subjective difficulty of insertion in anesthetized patients.
