Symptoms of Aspiration of gastric contents:
Gastric contents are visible in a company to a throat.
The raised PDV.
Plentiful tracheal secretion.
Cough, laryngospasm, rattles or retraction of a thorax.
Disturbances of breath, apnoea or tachypnea.
Given to a thorax X-ray analysis:
in 15 — 20% of cases not informatively;
pneumonic infiltrates and atelectases.
Situations with similar signs:
Anoxemia owing to other reasons.
Obstruction of ETT.
Bronchospasm owing to other reasons.
High PDV owing to other reasons.
Reasons of Aspiration of gastric contents:
Passive regurgitation or active vomiting to gastric contents at the patients deprived of an opportunity to protect respiratory tracts.
Treatment of Aspiration of gastric contents:
If during an intubation emergence of gastric contents is noticed or there was a suspicion on its pulmonary aspiration, immediately execute suction from a trachea prior to ventilation with positive pressure;
if ETT in a trachea, move the patient to situation with the head with raising of the right edge of a table down; carry out a suction catheter to ETT.
If there was an aspiration of solid particles, execute a bronkhoskopiya.
For removal of aspirirovanny particles lavage plus suction can be required.
Take sample of gastric contents for a research рН, crops and a bacterioscopy.
Cancel planned operation. The volume of an immediate surgery has to be limited to the minimum dictated by patient safety. You carry out auxiliary therapy.
Infusional therapy, preferably crystalloids, colloids — according to indications.
For prevention of stressful ulcers educate the patient Н^-блокаторы:
Cimetidinum in/in, 300 mg each 6 h;
ranitidine in/in, 50 mg each 6 h.

Lavage through ETT is usually not shown. Consider prescription of antibiotics:
the choice of an antibiotic has to be based on results of a bacteriological research of pulmonary aspirate;
preventive prescription of antibiotics is shown at aspiration with impurity of fecal masses.
