Jejunal probe

The Jejunalsonde is in the medical probe used form that the diet of patients is used when a supply of food in the stomach is not possible.

Surname

The name jejunal probe refers to the jejunum ( empty intestine ), the place where the exit of the probe is placed.

Depending on the location at which the probe is inserted into the patient, a distinction is made between probes inserted percutaneously, such as JET-PEG , PEJ and FNKJ probes and naso-jejunal probes.

description

The basic element of the jejunal probe is the flexible plastic tube with an outside diameter of 6 to 12  Ch (2–4 mm). The length of the tubing depends on the size of the patient and the point of entry and exit of the probe. Lengths up to 1.2 m are available. Jejunal probes are used with one to three channels. This enables simultaneous jejunal nutrition and gastric decompression with simultaneous ventilation. Up to five lumens are possible.

Percutaneous probes

PEJ probe

Percutaneous enteral jejunostomy . It is comparable to a PEG tube that ends in the jejunum.

JET-PEG or PEG-J probe

The name is derived from Jejunal tube through PEG.

FKJ probe

Fine needle catheter jejunostomy

PLJ

Percutaneous laparoscopic jejunostomy

Nasojejunal tube

The nasojejunal tube is suitable as a nasal tube for short-term care .

indication

Indications for jejunal probes,

• ICU patients with high gastroesophageal reflux
• severe blood poisoning , septic shock
• acute pancreatitis
• severe multiple trauma , traumatic brain injury
• Intensive care patients with gastric paralysis
• severe burns
• Peritonitis
• after complete surgical removal of the esophagus
• Bone marrow transplant
• in the absence of a stomach that had to be removed because of gastric ulcer or tumor

Contraindications

• Shock events of every genesis
• Insufficient supply of oxygen to the tissue (hypoxia)
  • Disturbance of the acid-base balance (acidosis)
• Acute abdomen; intestinal perforation
• severe acute blood loss into the lumen of the digestive tract
• mechanical intestinal obstruction (ileus)

Diet specifics

Since by placing the food into the jejunum part of the digestive tract with the held there digestion is omitted, the food should be adjusted The jejunum is not stretchable in contrast to the stomach. Therefore, feeding with jejunal tubes must always be continuous and slow.

advantages

The jejunal probe allows artificial nutrition in the form of enteral nutrition , even if the upper digestive tract is disturbed. Not only is it cheaper than parenteral nutrition, it is also more in line with physiological food intake.

disadvantage

Feeding with a jejunal tube must always be continuous. This means that the patient's mobility is impaired .
