Visual Tube Operation For Abdominal Puncture

1. Selection of parts

(1) Parapubic puncture point of the lower abdomen: 1cm above the midpoint of the line between the umbilical cord and the upper margin of the pubic symphysis, 1 ~ 2cm to the left or right. There are no important organs here, so puncture is safe and easy to heal.

(2) Puncture point in the left lower abdomen: the junction between the middle 1/3 and outer 1/3 of the connection between the umbilical cord and the left anterior superior iliac spine can avoid damage to the inferior abdominal artery here, and the intestine is relatively free and not easily damaged.

(3) Puncture point in lateral decubial position: the point where the umbilical plane intersects with the anterior or midaxillary line. This puncture is usually suitable for diagnostic puncture with a small amount of fluid in the peritoneal cavity.

2. Position reference

According to the condition and needs, it is advisable to sit, half decumbent and supine position, and try to make the patient comfortable, so that they can tolerate longer operation time.

Procedure of puncture

(1) Disinfect and spread towels.

(2) Local anesthesia.

(3) Puncture: The surgeon fixes the puncture skin with his left hand, and thrusts the needle vertically into the abdominal wall through the anesthetic area with his right hand. When the needle edge resistance suddenly disappears, it indicates that the needle tip has passed through the parietal peritoneum. After the assistant wears gloves, he fixes the needle with disinfection vascular forceps.
