When a woman undergoes chest puncture surgery, the surgical site needs to be determined first, then anesthesia is applied for puncture, and finally the fluid is aspirated. First, the second intercostal space in the midclavicular line or four to five intercostal spaces in the midaxillary line on the affected side of the patient is selected as the puncture site, and then the skin of the puncture site is disinfected from the inside out with alcohol and iodophor, respectively. After disinfection, 2% procaine was injected into the skin at the upper edge of the rib cage to complete local anesthesia of the pleural wall. After anesthesia was completed, the rubber rubber tube behind the puncture needle was clamped with hemostatic forceps, the skin at the puncture site was fixed tautly with the left hand, and the puncture needle was held in the right hand, and the puncture needle was inserted vertically and slowly along the anesthetized site through the upper edge of the ribs, and the puncture was successfully performed when the sense of resistance at the tip of the needle suddenly disappeared. When the puncture was completed, the left hand released the hemostatic forceps, and at the same time used the hemostatic forceps to assist in fixing the puncture needle. Subsequently, the extraction of thoracic fluid was started, and after the syringe was filled, the hose was clamped with hemostatic forceps, the syringe was removed, and the procedure was completed. After the chest puncture surgery, patients need to pay attention to maintain sufficient rest, ensure a light diet, pay attention to the puncture site dry and clean, avoid strenuous exercise, and immediately consult a doctor if discomfort is found.
