The extraction time after intestinal obstruction catheterization ranges from about 5 days to 3 weeks, and the exact extraction time should be decided according to the individual’s condition and physical recovery. Intestinal obstruction is a common surgical emergency abdomen, and catheterization of intestinal obstruction is a common surgical method for intestinal obstruction. By inserting a catheter for intestinal obstruction, the intestinal contents that cause bacterial ectopic reaction can be decompressed. The condition of intestinal obstruction varies from person to person. In most cases of simple intestinal obstruction, the catheter can be removed after the obstruction is relieved in 5-7 days after the insertion of the catheter. However, if the condition of intestinal obstruction is more serious and the adhesion is obvious, the time for extubation is relatively longer, and sometimes it may take 3~4 weeks until the condition is stabilized before the tube can be removed. After intestinal obstruction patients undergo intubation treatment, it is necessary to judge their recovery by observing the color and quantity of the drainage fluid in the drainage tube. If the body recovers well, the tube can be removed after the drainage flow is reduced, abdominal distension is reduced, and exhaustion occurs; if the body recovers poorly and the intestinal dynamics is insufficient, the time of tube removal can be extended appropriately. After intubation for intestinal obstruction, the removal of the tube should be considered after the gradual recovery of the intestinal function, in order to prevent poor recovery and recurrence of the disease.
