Precautions Of Abdominal Puncture Needle

1. During the operation, the patient should be closely observed. If dizziness, palpitations, nausea, shortness of breath, rapid pulse and pale face, etc., the operation should be stopped immediately and appropriate treatment should be carried out.

2. It should not be too fast or too much. Patients with cirrhosis usually do not drain more than 3000ml at a time, which can induce hepatic encephalopathy and electrolyte disorder. Attention should be paid to the color change of ascites during the discharge process.

3, if the outflow of ascites is not smooth, the puncture needle can be slightly moved or slightly change the position.

4. The patient was told to lie supine after surgery, and the puncture hole was located above to avoid further ascites leakage; For those with more abdominal water, 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 puncture needle head around slightly after the needle tip reaches the subcutaneous area 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, butterfly tape or cotton tape can be used to stick. After a large amount of liquid discharge, it is necessary to bundle with multiple abdominal bands to prevent abdominal pressure from plummeting; Dilatation of internal blood vessels 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. If the ascites is bloody, the suction or drainage should be stopped after the specimen is obtained.
