The whole procedure (beginning 2 minutes before the OGT insertion and continuing till 4 minutes after it is inserted) will be video recorded on a fixed camera focusing on the face of the patient. Neonate will be monitored using a non invasive vital signs monitor to monitor his heart rate and SpO2 changes during the entire procedure and for 2 minutes post procedure. The highest heart rate and lowest SpO2 obtained during the procedure till 2 minutes post procedure will be recorded. The research candidate will evaluate the pain response to the procedure according to the PIPP scale at time t=pre-procedure, t=intra-procedure,t=post 30 sec, t=post 1min, & t=post 2 min; wherein t denotes the time at which tube is inserted into the oral cavity. The research candidate will also monitor the time taken in the OGT insertion using a stopwatch. The neonatal nurse putting the OGT will rate the procedure as easy, difficult or very difficult.
