Precautions of abdominal puncture needle

1. During the operation, patients should be closely observed. In case of dizziness, palpitation, nausea, shortness of breath, rapid pulse and pallor, the operation should be stopped immediately and appropriate treatment should be carried out.

2. It should not be too fast or too much drainage. Generally, one drainage should not exceed 3000ml in patients with cirrhosis, and excessive drainage can induce hepatic encephalopathy and electrolyte disorder. Note the color change of ascites during drainage.

3. If the flow of ascites is not smooth, the puncture needle can be moved or changed slightly.

4. After surgery, the patient was instructed to lie supine, and the puncture hole was positioned above to avoid ascites leakage; For patients with a large amount of water in the abdomen, in order to prevent leakage, attention should be paid to not make the needle eye from the skin to the parietal peritoneum in a straight line during puncture. The method is to move the needle head slightly around after the needle reaches the subcutaneous layer through the skin, that is, with the assistance of the other hand, and then Pierce into the abdominal cavity. If the puncture hole continues to have ascites leakage, use butterfly tape or fire cotton tape. After discharging a large amount of liquid, it is necessary to bundle multiple abdominal belts to prevent sudden drop of abdominal pressure; Dilation of blood vessels in the viscera causes a drop in blood pressure or shock.

5. Pay attention to aseptic operation to prevent abdominal infection.

6. Abdominal circumference, pulse, blood pressure and abdominal signs should be measured before and after drainage to inspect the changes in the condition.

7, ascites for bloody specimens, should stop pumping or drainage.
