Intubation procedures in infants differ significantly from those in adults because infants' anatomy and physiology are different from those of adults. Intubation of babies is usually performed by specialized doctors in a hospital's neonatal unit or intensive care unit. The following is a simplified overview of the steps for intubating an infant, but please note that this is only a basic guide and is not a substitute for professional medical care.

Preparing the child:

Place the child on an open radiant warming table with the head slightly tilted back, approximately 30 degrees below the body.

Clean the child's mouth and nasal cavity, and suck out mucus and aspirated matter to prevent vomiting during the operation.

If necessary, provide the child with a resuscitation bag and a mask to provide positive pressure oxygen until the child's face turns red and the heart rate rebounds.

Preparation for intubation:

Prepare appropriate intubation tools, such as laryngoscope, endotracheal tube, nebulizer, dental pad, adapter tube, intubation forceps, etc.

Choose an endotracheal tube that is appropriately sized for your baby.

Anesthesia and sedation:

Depending on the child's condition, anesthesia or sedation may be needed to reduce discomfort during the procedure.

Operation process:

The operator stands on the side of the child's head, supports the mandible with his left hand, and inserts the laryngoscope from the right side of the mouth with his right hand.

Push the tongue to the left, and when the laryngoscope enters the epiglottis cartilage, tilt the tip of the lens slightly upward to expose the epiglottis cartilage and glottis.

Use your right hand to insert the endotracheal tube with the catheter core into it from the right side of the mouth, deep into the glottis, withdraw the stylet core, and continue to push the tube to the estimated length.

Insert the mouth plug, push out the laryngoscope, and secure the intubation tube.

Confirmation and monitoring:

Confirm whether the tube is in the trachea and not the esophagus by auscultation and observing the rise and fall of the chest.

Once the correct position is confirmed, secure the catheter with tape or other device to prevent it from shifting.

Monitor the child's vital signs, such as heart rate, respiration, blood oxygen saturation, etc.

Follow-up care:

Keep the intubation tube clean and unobstructed, and suction sputum regularly to avoid clogging with secretions.

Closely monitor changes in the patient's condition and adjust treatment plans in a timely manner.

Please note that infant intubation is a highly specialized medical procedure that needs to be performed by a specially trained neonatologist or intensivist. Anyone attempting this operation must have relevant specialist knowledge and skills and should seek professional medical support in an emergency.
