Abstract: This study investigated the anesthesia effect of senile laparoscopic appendix surgery under general anesthesia combined with ultrasound. Chosen 160 patients underwent laparoscopic appendectomy, with a prospective randomized trial protocol they were divided into ultrasound group and control group with 80 cases respectively. Both groups were treated with laparoscopic surgery under general intravenous anesthesia. Patients in the ultrasound group were combined with ultrasound-guided transversus abdominis plane block anesthesia based on the above anesthesia methods, and the control group was combined with anatomical methods to locate the transversus abdominis plane based on the above anesthesia methods, and intravenous self-controlled analgesia was used in both groups after operation. The results showed that the operation time of the ultrasound-guided abdominal transverse muscle plane block in the ultrasound group was shorter than in the control group, and the ultrasound-guided block was more accurate, and the block onset time was shorter than the control group (P<0.05). In terms of the dose of anesthesia-related drugs (propofol, remifentanyl), the ultrasound group was lower than that in the control group, and the amount of anesthetic drugs was lower in the ultrasound group (P<0.05). The VAS score at 6 hour and 12 hour after surgery at rest and the VAS score at 2 hour, 6 hour and 12 hour after surgery at cough state in the ultrasound group were all lower than in the control group (P<0.05). General anesthesia and ultrasound-guided anesthesia is more accurate and has better anesthesia effect, and patients have lower postoperative pain degree and higher comfort level.
