Slow water intake in LVT may be related to catheter drift, catheter blockage, and tubing wrapped in omentum. 1. Catheter drift: it may be related to the catheter drifting to the upper abdomen or other parts of the body, then slow water intake may occur. 2. Catheter blockage: Because the peritoneal fluid contains a large amount of protein, prolonged drainage may result in protein blockage of the catheter, which in turn leads to slow water intake into the abdominal cavity. 3. Duct wrapped by omentum: if the duct is wrapped by omentum, it will cause poor drainage of peritoneal fluid. In short, if the situation of slow water intake of peritoneal dialysis, it is recommended to go to the hospital in a timely manner to improve the abdominal plain film or imaging, to identify the cause of the timely treatment.
