Background: The I-gel is a second-generation supraglottic airway device that is built with a noninflatable elliptical gel material cuff and has a wide semirigid stem. The I-gel supralaryngeal seal has shown promising efficacy for both spontaneous and controlled ventilation under general anesthesia. The recommended, standard I-gel insertion technique is relatively challenging due to its shape and cuff size. Usually, the I-gel becomes entrapped at the oral cavity and requires excessive force to negotiate across the oropharynx, resulting in insertion resistance, tongue obstruction, insertion failure, and intraoral trauma. This case series evaluated a modified jaw thrust I-gel insertion technique because it is claimed to allow smooth and atraumatic I-gel placement in adults.
Case presentation: In this case series, ten male and female Indo-Aryan group of Asian patients aged 18-60 years were recruited for I-gel device placement through a modified jaw thrust technique for short to intermediate surgical duration in below-umbilical surgical procedures. Patient consent was obtained, and baseline vital signs such as electrocardiogram, noninvasive blood pressure, and peripheral oxygen saturation readings were recorded. Following preoxygenation, propofol 2 mg/kg was administered for anesthesia induction and nalbuphine 0.1 mg/kg for analgesia. In all patients, an I-gel was placed by the modified jaw thrust technique. The patient's demographics, number of attempts, I-gel insertion resistance, and insertion time duration were recorded.
Conclusion: The findings showed a 100% first-attempt insertion rate along with negligible insertion resistance and convincing insertion time duration with modified jaw thrust I-gel insertion technique. However, a blood-stained I-gel was observed in one male patient at the time of removal. The patient's demographics such as age, weight, American Society of Anesthesiologists status, and surgical and anesthesia duration were found not to be significant. The modified jaw thrust I-gel insertion technique could be considered as an alternative in adults when difficulty is encountered with the standard I-gel insertion technique.
