After intubation, the endotracheal tube was finally fixed after palpating endotracheal cuff at three sites (just below the cricoid cartilage, at suprasternal level and just below suprasternal notch). Fibre optic bronchoscopy will be done to find distance between tip of endotracheal tube and carina. This distance will be measured repeatedly, after pneumoperitoneum, after trendelenburg position and after making the patient supine at the end of surgery. Change in the distance will be noted.
The endotracheal tube (ETT) will be placed according to the black mark on the tube, post-intubation, the tube will be finally fixed after palpating endotracheal cuff at three sites (below cricoid cartilage, at suprasternal level and just below suprasternal notch). ETT cuff position will be scanned by sonography of airway to confirm the position of the proximal end of the ETT cuff. Fibre optic bronchoscopy will be done to find distance between tip of endotracheal tube and carina. This distance will be measured repeatedly 5 minutes after pneumoperitoneum, 10 minutes after trendelenburg position and 10 minutes after making the patient supine at the end of surgery. Change in the distance will be noted to confirm the migration of ETT.

RECRUITINGMeasure the distance between tip of endotracheal tube and Carina by fiber-optic bronchoscopy and measuring scale at various phases of robotic surgical procedure.
proper endotracheal tube placement is labelled when the distance between the tip of tube and Carina is more than 2.5 cm, after placement the tube by three point cuff palpation technique, its position will be assessed at respective time points.
Time frame: Throughout robotic surgical procedure, immediately after intubation, 5 minute after pneumoperitoneum, 10 minutes after trendelenburg position and after dedocking and making patient supine.pneumoperitoneum.
find the effect of cricod cartilage and supra-sternal distance on endotracheal tube tip to Carina distance.
cricoid cartilage to suprasternal distance changes with the position of neck, so it could affect the distance between the endotracheal tube tip and carina as the position of patient changes during various robotic surgical steps.
Time frame: Throughout robotic surgical procedure, immediately after intubation, 5 minute after pneumoperitoneum, 10 minutes after trendelenburg position and after dedocking and making patient supine.
