The process of laparoscopic surgery includes selection of anesthesia, position selection, establishment of artificial pneumoperitoneum, establishment of surgical channel, surgical operation and postoperative treatment. 1. Selection of anesthesia: most of laparoscopic surgery chooses endotracheal anesthesia, and epidural anesthesia can be used for some operations. Good anesthesia can reduce the patient’s pain and facilitate laparoscopic surgery. 2. Selection of body position: generally choose supine position or truncated position, empty the bladder before doing the operation, choose iodophor alcohol to disinfect the operation range, and cover it with sterile towel or bed sheet. 3. Artificial pneumoperitoneum establishment: Insert the pneumoperitoneum needle into 1cm above the navel. The operator injects carbon dioxide into the abdominal cavity to form an artificial pneumoperitoneum, which facilitates intraoperative operation and reduces bleeding. Establishment of surgical channel: According to the surgical requirements, make 2~4 surgical incisions in the abdomen, the length of which is about 0.5~1cm, and implant the sheath tube into the incision. 4. Surgical operation: by connecting the laparoscope with a cold light TV camera system, the operator first observes the lesions in the abdominal cavity or gynecological organs, and then takes surgical actions according to the specific lesions. More common laparoscopic surgeries include colon resection, cholecystectomy, appendectomy and hysterectomy under laparoscopic conditions. 5. Post-operative management: After the operation, the bleeding will be stopped completely, the intra-abdominal gas will be released, the trocar puncture needle will be withdrawn, the surgical opening will be sutured, and the patient will be bandaged with a sterile dressing. After the patient is awake, he will be sent to the ward for further treatment. After the operation, pay attention to reasonable diet, nutritional balance, and follow the doctor’s instructions for treatment.
