Supraglottic airway devices are very useful devices in short duration surgeries with or without muscle relaxants with lesser hazards of intubation reflexes. This prospective, randomized study was conducted in 60 spontaneously breathing patients undergoing for breast surgery[Group I - I-gel insertion(n = 30) and Group L - LMA insertion (n =30)] of ASA grades I/II, in the age group of 18-60 years, body weight 30-50 kg. Both groups were compared with respect to insertion time, insertion attempts, insertion failure and hemodynamic parameters (pulse, blood pressure, sp02) and peri operative complications. On the night prior to the operation all patients received Tab. Alprazolam 0.5 mg and Tab. Ranitidine 150 mg. Hemodynamic parameters recorded 5 min before induction. All patients were given Inj. Glycopyrrolate 0.2 mg, Inj Fentanyl 2mcg/kg and then induction was done with Inj Propofol 2mg/kg body weight. The I-gel size3 were used in Group I patients and LMA classic size 3 were used in Group L patients. After confirming the correct placement, LMA-C or I-gel was connected to breathing system and maintenance were done with nitrous oxide, oxygen and isoflurane. After completion of the surgery, anesthetic agents were discontinued allowing smooth recovery of the patient. The devices was removed after the patient regained consciousness spontaneously and responded to verbal command to open the mouth .Chi-square test and independent t-test used for statistical analysis. Mean insertion time for the I-gel (8.810 ± 0.1914,sec)was lower than that of the LMA (10.66 ± 0.1894sec) (P < 0.0001).No. of insertion attempts are similar in both groups(p value = 0.7282].There is no statistical difference in pulse rate, blood pressure and spo2 during insertion time of both groups. No peri operative and postoperative complications regarding insertion and post removal was reported during the study.
