[Physiopathology and principles of intensive care in intestinal obstructions].
The physiopathology of intestinal obstruction consists of increased intestinal peristaltis, distension by gas and fluids, contraction of the extracellular fluid volumes (plasma and interstitial sectors) and bacterial proliferation. To this must be added, in obstruction by strangulation, the passage of bacteria and bacterial products into the general circulation and the peritoneal cavity through an ischaemic or necrotic intestinal wall. Metabolic disorders consist of water, sodium and potassium deficits and acid-base disturbances. Water and electrolyte replacement should take into account the deficits that existed at the beginning of treatment, the additional losses expected during treatment and the needs for daily maintenance of water and electrolyte balance. The therapeutic procedure is simple provided it is systematized.
