Objective: To explore the clinical effect of nerve block combined with tracheal intubation general anaesthesia in elderly patients undergoing hip surgery.

Methods: A total of 74 elderly patients who underwent hip surgery in our hospital from April 2017 to April 2019 were selected as the research subjects. The patients were randomly divided into two groups by a simple random grouping method. The patients in the study group (n=37) received nerve block combined with general anaesthesia for tracheal intubation, and the patients in the control group (n=37) received general anaesthesia for tracheal intubation. Heart rate (HR), diastolic blood pressure (DBP) and systolic blood pressure (SBP) were observed before induction of anaesthesia (T0), after loss of consciousness (T1), immediately after endotracheal intubation (T2), 2 minutes after endotracheal intubation (T3) and at extubation (T4), as well as pain scores at 6, 12 and 24 hours after the operation and the incidence of complications.

Result: Repeated-measurement variance analysis showed significant differences between groups, with time and group as the main effect factors (P < 0.05). The HR, DBP and SBP in the study group were not significantly different from those in the control group (P>0.05), whereas the HR, DBP and SBP in the control group were significantly different (P<0.05). No significant difference was found in hemodynamic parameters at T0 and T1 between the two groups (P>0.05). HR, DBP and SBP at T2–T4 in the study group were lower than in the control group (P<0.05). Repeated measurements of variance analysis showed significant differences in visual analogue scale (VAS) scores between groups, with time and group as the main factors (P<0.05). The VAS scores of the study group at 6, 12 and 24 hours after the operation were significantly lower than those of the control group (P<0.05). The incidence of complications in the study group was significantly lower than in the control group (P<0.05).

Conclusion: The application of nerve block combined with tracheal intubation general anaesthesia in elderly patients undergoing hip surgery was beneficial to maintaining stable haemodynamics, alleviating early postoperative pain and reducing complications, so it has certain clinical application value.
