Nasotracheal intubation for giving general anesthesia

 Nasotracheal intubation is performed to anesthetise the patient before surgery. Intravenous line is started first using a venflon. Injection pentathol sodium is used to induce anesthesia. Injection scoline is used to paralyse voluntary muscle. Respiratory muscles are paralyzed. Patient is oxygenated using oxygen mask. Oxygenation is performed for one full minute. Endotracheal tube of appropriate size is used to intubate. This tube is passed through the nasal cavity. Macintosh laryngoscope is used to keep the mouth open and a megils forceps is used to guide the endotracheal tube under the epiglottis into the trachea. The site of the endotracheal tube is verified by auscultating for breath sounds. Injection Pavlon is used to keep the patient paralysed. A mixture of nitrous oxide and oxygen is administered via the endotracheal tube for maintaining anesthesia. After surgery is over a reversal drug is administered (Neostigmine or edrophonium). This drug reverses the paralysis caused by pavulon (Pancuronium). After injecting reversal drug the endotracheal tube is removed after proper suction of the endotracheal tube. This process is known as extubation.
