目的研究分析气压泵联合肢体锻炼与低分子量肝素钠预防ICU长期住院患者下肢深静脉血栓形成的效果评价。方法选取该院30例ICU长期住院患者为研究对象(2015年2月-2016年3月收治),随机分为对照组和实验组,每组患者15例。对照组进行气压泵联合肢体锻炼,实验组进行低分子量肝素钠治疗。实验组与对照组患者连续治疗21 d,比较分析两组患者相关临床指标。结果经过治疗后,实验组全血黏度高切与全血黏度低切为(8.52±1.28)mpa·s与(3.20±0.62)mpa·s,对照组全血黏度高切与全血黏度低切为(9.20±1.22)mpa·s与(3.65±0.74)mpa·s,差异具有统计学意义(P<0.05)。对照组中,1例患者出现深静脉血栓。实验组患者中,3例出现深静脉血栓。实验组发生深静脉血栓率为6.7%显著低于对照组深静脉血栓发生率为20.0%,差异有统计学意义(P<0.05)。结论低分子量肝素钠与气压泵联合肢体锻炼相比,预防ICU长期住院患者下肢深静脉血栓形成的临床疗效为理想,能够显著降低深静脉血栓发生率,帮助患者恢复健康,具有临床推广的意义。
Objective To study the effect of pneumatic pump combined with limb exercises and low molecular weight heparin on the prevention of deep venous thrombosis of lower extremities in ICU long term inpatients. Methods 30 long-term hospitalized patients with ICU in our hospital were selected as the research object (February 2015-March 2016) and randomly divided into control group and experimental group, 15 cases in each group. Control group were combined with pneumatic pump limb exercises, the experimental group of low molecular weight heparin treatment. The patients in experimental group and control group were treated for 21 consecutive days, and the relative clinical indexes of two groups were compared. Results After treatment, the whole blood viscosity and the whole blood viscosity of the experimental group were (8.52 ± 1.28) mpa · s and (3.20 ± 0.62) mpa · s, respectively. The control group had high whole blood viscosity and low whole blood viscosity (9.20 ± 1.22) mpa · s and (3.65 ± 0.74) mpa · s, the difference was statistically significant (P <0.05). In the control group, 1 patient developed deep vein thrombosis. In the experimental group of patients, deep vein thrombosis occurred in 3 cases. The rate of deep venous thrombosis in the experimental group was 6.7%, which was significantly lower than that in the control group (20.0%), the difference was statistically significant (P <0.05). Conclusion Low molecular weight heparin sodium is superior to pneumatic pump combined with limb exercises in preventing long-term lower extremity deep venous thrombosis in ICU patients. It can significantly reduce the incidence of deep venous thrombosis and help patients recover health. It is of clinical significance.
