To explore the application effect of local nerve block combined with intravenous dexmedetomidine in elderly inguinal hernia repair.

Sixty elderly patients with inguinal hernia who received surgical treatment in Lujiang County People's Hospital of Anhui Province from June 2020 to June 2022 were selected. According to the random number table method, all patients were divided into a control group ( local nerve block + intravenous saline ) and an experimental group ( local nerve block + intravenous dexmedetomidine ), 30 cases in each group. Compare the heart rate and mean arterial pressure of patients in the two groups at different time points (before anesthesia, after anesthesia, at the beginning of surgery, and 15 and 30 minutes after anesthesia). The onset time and maintenance time of anesthesia were compared between the two groups. The analgesic effects of the two groups were compared. The pain feelings of patients in the rest state after operation were compared between the two groups. The pain relief satisfaction of the two groups was compared. The postoperative adverse reactions of the two groups were compared.

At the beginning of surgery and 15 min after anesthesia, the heart rate of patients in the experimental group was significantly lower than that of patients in the control group (P<0.05), and the differences in heart rate and mean arterial pressure between the two groups at all other time points were not statistically significant (P>0.05). The onset of anesthesia in experimental group patients was less than that in control group patients, and the maintenance of anesthesia was better than that in control group patients (P<0.05). The analgesic effect of patients in the experimental group was better than that of patients in the control group (P<0.05). The pain scores in the resting state at different time points after surgery were higher in the control group than in the experimental group patients (P<0.05). The analgesic satisfaction scores of patients in the experimental group were significantly higher than those of patients in the control group (P<0.05). The data of all types of postoperative adverse reactions in the 2 groups were not statistically different (P>0.05).

Local nerve block combined with intravenous dexmedetomidine has a good effect on anesthesia and postoperative pain relief in elderly inguinal hernia repair, but may induce a decrease in heart rate in these patients.
