Objective:To investigate the intervention effect of decision aid on the fear of falling in elderly patients after total hip arthroplasty.Methods:This study was a quasi experimental research. From June 2021 to November 2021, 84 patients after total hip arthroplasty who were admitted to the Department of Orthopedics of Zhengzhou Central Hospital Affiliated to Zhengzhou University were selected as the research objects. According to the order of admission, they were divided into the control group (42 cases, 2 cases fell off ) and the observation group (42 cases). The control group was given routine nursing care and guidance for fear of falling, while the observation group was given a decision-making aid intervention program on the basis of the control group. The time to first getting out of bed, the scores of Modified Falls Efficacy Scale (MFES), Generalized Anxiety Disorder (GAD-7) and Harris Hip Score (HHS) were compared between two groups.Results:The time to get out of bed for the first time in the observation group was (42.71 ± 6.41) h, lower than that in the control group (49.95 ± 5.73) h, and the difference was statistically significant ( t=5.38, P<0.05). Twelve weeks after discharge, the GAD-7 score in the observation group was (4.64 ± 1.43), which was lower than that of the control group (6.85 ± 1.83), and the difference was statistically significant ( t=6.10, P<0.05). The score of the MFES in the observation group was [8.50(8.00,10.00)], which was higher than that in the control group [7.50(7.00,8.00)], and the difference was statistically significant ( Z=-6.26, P<0.05). The hip joint function score of the observation group was (81.74 ± 4.24), which was higher than that of the control group (74.30 ± 4.51), and the difference was statistically significant ( t=7.69, P<0.05). Conclusions:Decision support can advance the time of downward movement of elderly patients after total hip arthroplasty, reduce their anxiety and fear of falling, and improve hip function.

Objective To compare the safety and efficacy of direct thrombectomy versus bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke under different collateral circulation statuses.Methods Totally 93 patients with acute anterior circulation ischemic stroke admitted to the First Affiliated Hospital of Xinxiang Medical University from September 2020 to March 2023 were selected as the research subjects.Patients were divided into direct throm-bectomy group(n=47)and bridging thrombectomy group(n=46)based on the type of thrombectomy.Patients in the direct thrombectomy group received direct intravascular thrombectomy,while patients in the bridging thrombectomy group received intravenous thrombolysis with alteplase combined with mechanical thrombectomy.According computed tomography angiography,the collateral circulation Tan classification was applied to divide the patients into good collateral circulation sub-group and poor collateral circulation sub-group.The modified thrombolysis in cerebral infarction grading(mTICI)was used to evaluate vessel recanalization.Head computed tomography plain scan was performed at 24-48 hours postoperatively to assess if there was hemorrhagic transformation,and modified Rankin Scale score was performed at 90 days postoperatively.Information such as imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,prognosis and spontaneous non-traumatic symptomatic intracerebral hemorrhage(SICH)were collected.Results The age,gender,baseline Alberta stroke program early computed tomography score,baseline national institutes of health stroke scale score,proportions of hypertension,diabetes and atrial fibrillation,baseline systolic pressure,creatinine,baseline blood glucose,platelet count,occlusion site,stroke etiologies and collateral circulation status of patients in the two groups were not statistically significantly different(P＞0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between the two groups(P＞0.05).The hemorrhagic transformation rate of patients in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between patients with good collateral circulation and patients with poor collateral circulation in the two groups(P＞0.05).The hemorrhagic transformation rate of patients with good and poor collateral circulation in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).Conclusion Under different collateral circulation conditions,the safety and efficacy of direct thrombectomy and bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke are similar,but bridging thrombectomy is more likely to result in cerebral hemorrhage transformation compared with direct thrombectomy.
