What are the precautions for abdominal paracentesis and fluid drainage?
Ascites generally refers to the accumulation of fluid in the abdominal cavity. During abdominal paracentesis for ascites drainage, key considerations include close monitoring of the patient's condition, controlling the rate and volume of fluid removal, and maintaining aseptic technique. The details are as follows:
1. Monitor the Patient's Condition
The patient's condition must be closely observed throughout the procedure. If symptoms such as dizziness, rapid breathing, or nausea occur, the procedure should be stopped immediately. Severe symptoms require prompt symptomatic treatment.
2. Control the Rate and Volume
During abdominal paracentesis, care must be taken not to drain the fluid too quickly or in excessive amounts. It is recommended that the initial drainage volume be less than 1000 mL, with subsequent procedures limited to less than 3000 mL per session, to avoid rapid or excessive fluid removal that could lead to electrolyte imbalances.
3. Maintain Aseptic Technique
The entire procedure must follow strict aseptic principles. The puncture site and surrounding skin should be properly disinfected to minimize the risk of infection.
In addition, if the ascitic fluid appears bloody during the procedure, drainage should be stopped immediately after obtaining the specimen. Patients are advised to actively cooperate with their physicians during treatment.
