Abstract:

Objective To investigate the effect of anesthesia and analgesia and the influence on cognitive function of different routes of nerve block guided by ultrasound in breast cancer patients. Method A total of 100 breast cancer patients admitted to the 73rd Group Military Hospital of the PLA Army from January 2020 to January 2021 were selected and divided into a control group (intercostal nerve block + general anesthesia, 50 patients) and observation group (50 cases with chest wall nerve block + general anesthesia)by different surgical methods. The anesthesia and analgesia effect, cognitive function and occurrence of adverse reactions were compared between the two groups. Result Compared with the control group, the pain scores of patients in the observation group were significantly lower after leaving the recovery room and 24 hours after operation (P ＜ 0.05); after operation, the level of cognitive function in the observation group was significantly higher than that in the control group (P

＜ 0.05); the incidence of adverse reactions in the observation group was 8.00%, significantly lower than 24.00% in the control group (P ＜ 0.05). Conclusion For breast cancer patients, the use of chest wall nerve block has achieved good results in analgesia, greatly improved the patient's cognitive function, reduced the adverse reaction rate.
