Background:Supraglottic-airway devices (SAD) are divided into first-generation and second-generation devices. Baska Mask and i-gel device are the two commonly used second-generation SADs in anaesthetic practice. This study compares the i-gel and Baska Mask in terms of efficacy and safety as a ventilatory device in anaesthetized patients undergoing elective surgeries.
Materials and Methods: The study was carried out in Department of Anaesthesiology, Government Medical College and Dr.Sushila Tiwari Hospital, Haldwani. Patients were allocated into 2 groups: Group A (i-gel, n=35) and Group B (Baska Mask, n=35). All patients were pre-oxygenated for 3-minutes and anaesthesia was induced. Successful insertion of the device was confirmed by chest wall movement, auscultation of breath sounds and square wave capnographic tracing. At the end of the surgical procedure, anaesthesia was discontinued and patients were reversed with the standard dose of neostigmine and glycopyrrolate after proper suctioning. Complications, if any were noted after 2 hours and 24 hours period.
Results: The mean age of the study population was 35.83±9.50 years. Among i-gel group, there were 24 (68.6%) males and 11 (31.4%) females. Among Baska Mask group, there were 20 (57.1%) males and 15 (42.9%) females. The percentage of patients with easy insertion was 80% and 68.6% for i-gel and Baska Mask respectively. The mean time taken for SAD was significantly more among Baska Mask (24.49±4.39) in comparison to i-gel (16.19±2.38). Sore throat at 2 hours was seen in 3 (8.6%) and 2 (5.7%) patients of i-gel and Baska Mask group respectively. Dysphagia at 2 hours was seen in 2 (5.7%) and 1 (2.9%) patient of i-gel and Baska Mask group respectively, while dysphagia at 24 hours was seen in 1(2.9%) patient of i-gel group only, also hoarseness at 2 hours was seen in 1(2.9%) patient of i-gel group. Incidence of all the complications reported with i-gel and Baska Mask group were comparable.
Conclusion: This study demonstrated that both Baska Mask and i-gel provided a similar performance in airway management. In terms of the total time taken for insertion, i-gel has a lesser time of insertion than the Baska mask. The success rate of insertion of Baska Mask and i-gel was comparable and ease of insertion was also comparable. Complications observed in both devices were minimal.

The i-gel in paediatric patients is a single use supraglottic airway which was officially
launched for use in January 2010. This device differs from other supraglottic airways in that
it has an anatomically designed mask made up of thermoplastic elastomer & the cuff which
does not require inflation with air. Evaluation of i-gel in adult patient has shown that it is easy
to insert and provides an effective airway in majority of patients. We conducted a
prospective, randomized, single blind study to compare i-gel and cLMA in the Indian
paediatric population of age group from six months to 8 years belonging to ASA physical
status I or II, scheduled to undergo elective surgery under general anaesthesia. We analysed igel
with cLMA of paediatric sizes for peak airway pressures and oropharyngeal seal pressure.
And we found i-gel provides better OSP and lower PAP than cLMA making this better
device for controlled ventilation.

Evaluation of the Efficacy of I-gel Supraglottic Airway Device in Relation to Ease of Insertion, Time Taken to Establish Effective Ventilation and Gastric Insufflation

European Journal of Molecular & Clinical Medicine, 2022, Volume 9, Issue 3, Pages 5712-5718

Introduction: I-gel is a novel supraglottic airway device with anatomically designed,
non-inflatable mask, which is soft gel like and transparent made of medical grade
thermoplastic elastomer called styrene ethylene butadiene styrene.The present study is
carried out to evaluate the efficacy of I-gel with regard to easiness of insertion of I-gel,
number of insertion attempts, time taken and maneuvers required; time taken to
establish effective ventilation and gastric insufflation.
Material and Methods: A prospective randomized controlled study was conducted on 40
patients scheduled for elective surgical procedures and requiring controlled ventilation.
Patients were induced with thiopentone 4-6 mg/kg. Size 3 I-gel was used in patients
weighing 30-60 kg and size 4 I-gel was used in patients weighing 60-90 kg. Correct I-gel
insertion was assessed clinically by subjective assessment of appropriate length of
airway tube outside the mouth, gastric insufflation and adequacy of manual ventilation
which was assessed by proper chest expansion and presence of CO2 waveform.
Results: The study included the patients with MMP classI/II and ASA grade I/II. The
mean time taken for insertion was 14.75±1.48 seconds and 95% patients required single
attempt for successful device insertion and 5% patients required second attempt for
successful device insertion. In two patients head tilt and chin lift maneuver was used for
the correct placement of the device.In 38(95%) patients the insertion of the I-gel was
scores very easy(grade1) and in 2(5%) patients it was scored easy(grade 2).
Conclusion: I-gel is an effective supraglottic airway device which can be rapidly
inserted. It provides a leak free glottis seal during positive pressure ventilation. The
nasogastric tube can be easily placed

A Study to Observe the Hemodynamic Changes Following Insertion of I-gel and to Access Incidence of Any Postoperative Side Effects

Introduction: Supraglottic airway devices (SADs) are used to keep the upper airway
open to provide unobstructed ventilation. I-gel is a second generation extraglottic
airway device. SADs now provide successful rescue ventilation in > 90% of patients in
whom mask ventilation or tracheal intubation is found to be impossible.The present
study was carried to observe the hemodynamic changes following insertion of I-gel and
to evaluate any incidence of post – operative sore throat or any other side effects.
Material and Methods: A prospective randomized controlled study was conducted on 40
patients scheduled for elective surgical procedures and requiring controlled ventilation.
Patients were induced with thiopentone 4-6 mg/kg. Size 3 I-gel was used in patients
weighing 30-60 kg and size 4 I-gel was used in patients weighing 60-90 kg. Correct I-gel
insertion was assessed clinically by subjective assessment of appropriate length of
airway tube outside the mouth, gastric insufflation and adequacy of manual ventilation
which was assessed by proper chest expansion and presence of CO2 waveform.
Results: Slight rise in MAP of 97.58±9.29 mmHg from BL value of 93.13±9.03 was
observed (p=0.836). The mean %age rise was 4.66±2.83 after insertion of the I-gel in
comparison with the base line value. It was found to be statistically insignificant.
Oxygen saturation was maintained between 99-100% for all the patients till the end of
the surgery. There was not any significant change in the ETCO2 after I-gel insertion. As
revealed from the data there was very less incidence of post-operative complications.
Two patients complained of sore throat at 6 hours and 24 hours post-operatively.
