| description | Introduction: Supraglottic Airway Devices (SAD) can be
used instead of endotracheal intubation in both regular and
complicated airway situations. Auragain, ProSeal and Protector
Laryngeal Mask Airways (LMA) are second generation LMAs.
They have a separate provision for gastric drainage. Auragain
LMA is a recent second-generation Supra Glottic Airway
device (SGA) with a pre-formed curved shaft and a double
lumen having wider airway path to aid endotracheal intubation.
ProSeal LMA also has a double cuff for better sealing to prevent
gastric insufflation and aspiration. Protector LMA has two
large-volume gastric drainage channels and an integrated cuff
pressure indicator called the cuff pilot which enables application
of higher respiratory pressure.
Aim: To compare the adequacy of placement of Auragain,
ProSeal and protector LMAs by vocal cord visualisation using
fiberoptic bronchoscopy.
Materials and Methods: A randomised clinical study was
conducted in the Department of Anaesthesiology, SRM Medical
College Hospital and Research Centre, Chennai, Tamil Nadu,
India, from October 2021 to October 2022 among 120 patients.
They were allocated by computer-generated random numbers
into three groups namely Auragain, ProSeal and Protector
LMA Group. The adequacy of placement of LMA through
Fiberoptic Bronchoscopy (FOB) using Brimacombe and berry
scoring, Oropharyngeal Leak Pressure (OLP), time of insertion
of LMA, number of attempts for insertion, ease of insertion
of LMA, Ryle’s tube insertion success rate and postoperative
complications were recorded immediately, after an hour and
24 hour, respectively. Statistical analysis was performed using
International Business Machines-Statistical Package for the
Social Sciences (IBM-SPSS) software version 21.0.
Results: The mean±Standard Deviation (SD) age in Auragain
groups, ProSeal and Protector LMA groups was 41.35±12.96
years, 36.58±12.62 years and 36.65±12.50 years, respectively.
The demographic data, procedures and duration of
anaesthesia were comparable between the three groups. The
mean insertion time (in seconds) was lower in the Auragain
LMA group (16.80±3.66) when compared to protector LMA
(20.20±6.93) and ProSeal LMA (21.68±4.44) with statistically
significant difference (p-value<0.0001). The OLP (in cm H2O)
was more with ProSeal LMA (34.43±5.26) than Protector LMA
(32.60±3.45) and Auragain LMA (28.55±1.85) with statistically
significant difference (p-value<0.0001). The fiberoptic view
was better with ProSeal LMA and statistically significant with
Grade 4 (p-value<0.0001) and Grade 3 (p-value=0.007). The
three devices were comparable in terms of ease and success
of insertion of LMA, ease of placement of gastric tube and
postoperative symptoms.
Conclusion: It can be concluded that the ProSeal LMA offers
better airway access and safety despite being slightly difficult to
insert compared to Ambu Auragain or Protector LMA. |
