 Clinical situation:

  • Patient M., 30 years old, after an accident, has multiple fractures of the lower jaw and tissue damages. An active feeding is not possible due to injuries. 
  • Feed the patient with a nasogastral tube.

Order of the skill performance:

 The main indications: tumours, especially in the region of head, neck and stomach,jaw injury, comas, mental disorders-psychological absence of appetite, severe depression, swallowing and speech disorder, swelling of the tongue, pharynx, larynx

 The main contra-indications: peptic ulcer disease in the acute stage, acute pancreatitis, severe forms of malabsorbtion, gastrointestinal bleeding, shock, anuria, severe vomiting.

Preparatory stage:

  •       Check the integrity of the packages of sterile medical instruments and sterile dressings, the expiration date.
  •       Greet the patient, introduce yourself, identify the patient (specify the last name, first name and patronymic of the patient), check the appointment sheet
  •       Inform the patient about the procedure, get verbal consent to giving it

  •       Place the disconnected Janet syringe and trays in the Disinfection of MI container.
  •       Place the Enterolin inside Plastic container
  •       Place all MI packages inside Packages container
  •       Take off the apron from the patient, place the disposable apron in the container “Disinfection of dressings, PPE”, in case of using a reusable apron, disinfect it by spray metod.
  •       Place the absorbent sheet inside waterproof bag for linen
