Intervention / Comparator Agent  
Type  Name  Details 
Comparator Agent  i-gel  i-gel of appropriate size will be inserted with the patient’s head in sniffing position. The lubricated i-gel will be grasped firmly along the integral bite block. The device will be positioned so that the i-gel cuff outlet is facing towards the chin of the patient. The chin will be gently pressed down before proceeding to insert the i-gel. The leading soft tip will be inserted into the mouth of the patient in a direction towards the hard palate. The device will be glided downwards and backwards along the hard palate with a continuous but gentle push until a definitive resistance is felt. At this point the incisors should be resting on the integral bite-block .i-gel has a non-inflatable cuff and does not need inflation. 
Intervention  LMA Protector  LMA Protector of appropriate size will be introduced. Cuff of the device will be fully deflated and posterior surface of the mask and airway tube will be lubricated with water soluble lubricating jelly. The patient’s head and neck will be placed in sniffing position. The mouth will be opened with the investigator’s nondominant hand. Using the dominant hand, device will be introduced in the oral cavity pressing the posterior part of the tip of the mask against the hard palate. Device will be advanced further into the hypopharynx in one smooth circular movement pressing against the contours of the hard and the soft palate, until definite resistance is felt. Cuff of LMA Protector will be inflated with air to 60 cm of water using cuff pressure gauge . Intracuff pressure will be checked every 30 minutes and adjusted to 60 cm of water throughout anaesthesia. The LMA Protector cuff pilot technology will be compared to the cuff pressure measured by a manometer.

Brief Summary    This prospective randomised study has been designed to evaluate and compare the clinical efficacy of LMA Protector with i-gel as a ventilatory device in adult patients undergoing elective surgery under general anesthesia with controlled ventilation.
We hypothesise that Laryngeal Mask Airway Protector will have a better clinical efficacy as a ventilatory device as compared to i-gel in terms of higher oropharyngeal leak pressure in adult patients undergoing elective surgery under general anaesthesia with controlled ventilation.
This study will be conducted in 100 adult patients of either gender, in age group of 18 to 60 years, weighing 30- 70 Kg, American society of Anaesthesiologists (ASA) physical status I and II undergoing elective surgery under general anaesthesia with controlled ventilation in supine position. 

 Patients will be randomly allocated to two groups of 50 each.
Group I- i- gel will be inserted in the patients (n= 50)
Group P- LMA Protector will be inserted in the patients(n= 50)
Computer generated random number table will be used to allocate patients to two groups. Allocation will be concealed in sequentially numbered  sealed opaque envelopes. Once a patient gives consent to enter the study, an envelope will be opened and the patient will then be offered the allocated group.

Preanaesthetic evaluation of the patient will be done ,those falling under exclusion criteria will be excluded, written informed consent will be taken from the patient
Patient will be taken to operation theatre . Baseline vitals noted
preoxygenation for 3 minutes with 100% oxygen
Induction with Fentanyl 2 μ/kg, Propofol 2-2.5mg/kg followed by vecuronium 0.1mg/kg
Face mask ventilation with Isoflurane (1-1.5%) in 50 % oxygen and 50% nitrous oxide for 3 minutes
Group P- LMA - Protector inserted n=50
Group I- i- gel inserted n=50

Confirmation of achieving effective ventilation and correct gastric catheter insertion
Parameters to be noted
1.Oropharyngeal seal pressure 2 .Insertion characteristics-Number of attempts taken for successful insertion of device, time for achieving effective ventilation, ease of insertion of device, ease of gastric catheter insertion 3.Anatomical alignment of device to glottic opening   

Postoperative pharyngolaryngeal morbidity noted

Primary objective is to compare Laryngeal Mask Airway Protector with i-gel in terms of oropharyngeal leak pressure in adult patients undergoing elective surgery under general anaesthesia with controlled ventilation.
SECONDARY OBJECTIVES:
To compare following insertion characteristics of Laryngeal Mask Airway Protector with i-gel in adult patients undergoing elective surgery under general anaesthesia with controlled ventilation:
-Number of attempts taken for successful insertion of device, 
-Time for achieving effective ventilation, 
-Ease of insertion of device, 
-Ease of gastric catheter insertion  
-Fibreoptic bronchoscopic score regarding anatomical alignment of device
