Will abdominal puncture bleed?

Before abdominal puncture, appropriate puncture needle was selected and checked whether the puncture needle was unobstructed. The surgeon fixed the skin of puncture part with the left hand, and held the needle in the right hand to Pierce the abdominal wall vertically through the anesthesia place. When the resistance of needle front disappeared suddenly, indicating that the needle tip had passed through the parietal peritoneum, ascites could be extracted and samples were kept for examination. Diagnostic puncture can be performed directly with a 20ml or 50ml syringe and an appropriate needle. When a large amount of fluid is released, no. 8 or 9 needle can be used, and a rubber tube is connected to the needle holder. The assistant fixes the needle with disinfection vascular forceps, holds the hose, adjusts the speed with infusion clamp, and puts the ascites into the container for measurement and inspection.

After drainage, pull out the puncture needle, cover with sterile gauze, press with fingers for several minutes, and then fix with adhesive tape. After a large amount of fluid discharge, it is necessary to bind multiple abdominal bands to prevent sudden drop in abdominal pressure and dilation of internal organs from causing blood pressure drop or shock.

After the operation, the patient was ordered to lie flat, and physical examination and blood pressure and pulse were measured.
