间歇充气加压预防神经重症患者下肢静脉血栓的临床效果分析

Clinical Effect Analysis of Intermittent Inflation and Compression for Prevention of Lower Limb Venous Thrombosis in Neurologically Critically Ill Patients

目的:探究间歇充气加压(IPC)预防神经重症患者下肢静脉血栓的临床效果。方法:选取2021年1月—2022年7月钦州市第一人民医院重症医学科收治的66例神经重症患者作为研究对象,参照随机数字表法分为对照组和观察组,各33例。对照组给予常规护理干预,观察组在对照组基础上采用IPC。比较两组下肢静脉血栓发生率、下肢静脉血流速度、下肢周径。结果:观察组下肢静脉血栓发生率低于对照组,差异有统计学意义(P=0.046)。治疗后,观察组腘窝静脉、股总静脉、股浅静脉血流速度均快于对照组,差异有统计学意义(P<0.001)。观察组双下肢膝下10 cm、膝上15 cm周径均小于对照组,差异有统计学意义(P<0.001)。结论:IPC预防神经重症患者下肢静脉血栓的临床效果显著,能够提高下肢静脉血流速度,改善下肢肿胀情况,降低下肢静脉血栓发生率。

Objective:To investigate the clinical effect of intermittent inflation and compression(IPC)for the prevention of lower limb venous thrombosis in neurologically critically ill patients.Methods:Sixty-six neurologically critically ill patients admitted to the Department of Critical Care Medicine of Qinzhou First People's Hospital from January 2021 to July 2022 were selected as study subjects and divided into a control group and an observation group with thirty-three cases each with reference to the random number table method.The control group was given conventional nursing intervention,and the observation group was given IPC on the basis of the control group.The incidence of lower limb venous thrombosis,lower limb venous blood flow velocity,and lower limb circumference were compared between the two groups.Results:The incidence of lower limb venous thrombosis in the observation group was lower than that in the control group,and the difference was statistically significant(P=0.046).After treatment,the blood flow velocity of popliteal vein,common femoral vein and superficial femoral vein in the observation group was faster than that in the control group,and the difference was statistically significant(P<0.001).The circumference of 10 cm below the knee and 15 cm above the knee of both lower limbs in the observation group was smaller than that in the control group,and the difference was statistically significant(P<0.001).Conclusion:The clinical effect of IPC in preventing lower limb venous thrombosis in neurologically critically ill patients is significant,which can improve the lower limb venous blood flow velocity,improve the swelling of lower limbs and reduce the incidence of lower limb venous thrombosis.
