The efficacy of fascia iliaca compartment block combined with general anesthesia for total hip arthroplasty

Abstract

Objective To investigate the efficacy of fascia iliaca compartment block combined with general anesthesia for total hip arthroplasty. Methods Fifty patients underwent total hip arthroplasty were divided into trial group or control group by random digits table method with 25 cases each. Preoperatively, both groups were given fascia iliaca compartment block with the trial group receiving 60 ml 0.25% ropivacaine and the control group receiving 60 ml 0.9% sodium chloride. Both groups received general anesthesia. The consumption of general anesthetics and intraoperative hemodynamic variation in the 2 groups were recorded. The recovery time, extubation time, observer's assessment of alertness/sedation score (modified OAA/S) at 15 and 30 min postoperative and visual analog score (VAS) at postoperative instantly were compared between the 2 groups. Results The consumptions of propofol and remifentanil during maintenance of anesthesia in trial group were significantly lower than those in control group, and there were statistical differences: (250±40) mg vs. (420±85) mg and (300±50) μg vs. (600±150) μg, P<0.01. The recovery time and extubation time in trial group were significantly shorter than those in control group, and there were statistical differences: (7.2±4.5) min vs. (16.2±7.1) min and (8.0±2.8) min vs. (20.0±8.3) min, P<0.01. The modified OAA/S at 15 and 30 min postoperative in trial group were significantly higher than those in control group, and there were statistical differences: (4.3±0.3) scores vs. (3.0±1.2) scores and(4.6±0.2) scores vs. (3.9±0.8) scores, P<0.01. The VAS at postoperative instantly in trial group was significantly lower than that in control group, there was statistical difference: (1.6±0.9) scores vs. (4.5±0.8) scores, P<0.01. The degree of satisfaction in trial group was better than that in control group, and there was statistical difference (P<0.05). Conclusion Compared with general anesthesia alone for total hip arthroplasty, the fascia iliaca compartment combined with general anesthesia has better hemodynamic stability, marked reduction of consumption of general anesthetics, rapid recovery and good postoperative analgesia.
