The effect of fascia iliaca compartment block continuous analgesia in the early stage on early postoperative cognitive in patients with hip fractures / 中国医师进修杂志

ABSTRACT

Objective:To investigate the effect of fascial iliaca compartment block (FICB) continuous analgesia in the early stage after admission on early postoperative cognitive and motor function in elderly patients with hip fractures.Methods:A total of 80 elderly patients with hip fractures admitted toThe First Affiliated Hospital of Tsinghua University from June 2018 to June 2020 were selected and randomly divided into the control group and the observation group, with 40 cases in each group. The control group adopted the routine postoperative analgesia regimen, while the observation group adopted FICB analgesia immediately after admission to the hospital until before the operation. Postoperative analgesia pattern was consistent with that of the control group, and both groups were given postoperative analgesia for 48 h. The scores of visual analogue scale (VAS), mini mental state assessment scale (MMSE), Harris hip score (Harris) and surgical indexes, stress indexes and incidence of adverse reactions were compared between the two groups.Results:The levels of postoperative blood glucose, cortisol, angiotensin Ⅱin the observation group were lower than those in the control group (5.21 ± 1.03) mmol/L vs. (7.03 ± 1.06) mmol/L, (643.08 ± 77.28) nmol/L vs. (747.96 ± 82.80) nmol/L, (41.03 ± 5.22) ng/L vs. (57.15 ± 8.16) ng/L, there were statistically differences ( P<0.05). The dosage of sufentanil in the observation group was lower than that in the control group (27.48 ± 3.25) mg vs. (58.54 ± 4.86) mg, there was statistically difference ( P<0.05). The scores of VAS score at 12 h before surgery, 12 h and 48 h after surgery in the observation group were lower than those in the control group, and the scores of MMSE score were higher than those in the control group, there were statistically differences ( P<0.05). After the surgery, the Harris scores in the observation group was higher than that in the control group (76.09 ± 6.11) scores vs. (65.62 ± 6.13) scores, there was statistically difference ( P<0.05). The incidence rate of postoperative cognitive dysfunction (POCD) in the observation group was lower than that in the control group 2.5%(1/40) vs. 15.0%(6/40), there was statistically difference ( χ2 = 3.91, P<0.05). Conclusions:FICB continuou sanalgesic in the early stage after admission of elderly patients with hip fracture is satisfactory, which can effectively relieve postoperative pain, while the stress response is relatively mild, the recovery of postoperative cognitive function and hip function is good.
