Effect of optimal time of intermittent pneumatic compression on deep venous thrombosis of critical patients in respiratory department / 中国实用护理杂志

ABSTRACT

Objective:To investigate the effect of optimal time of intermittent pneumatic compression(IPC) on deep venous thrombosis (DVT) of critical patients in respiratory department.Methods:Totally, 105 critical patients in Department of Respiratory and Critical Care Medicine,Nanjing Drum Tower Hospital, Nanjing University Medical School from July 2018 to October 2019 were divided into experimental group 1, group 2 and group 3 by random digits table method, with 35 cases in each group. The experimental group 1 received IPC treatment with 30 min every time, twice a day; and group 2 received 40 min every time, twice a day; and group 3 received 1 hour every time, twice a day. The incidence of DVT and deep tissue injury was observed among three groups, meanwhile, the coagulation function index among three groups was compared before and after IPC treatment.Results:There was no significant difference in the incidence of DVT among the three groups ( P>0.05), however, the deep tissue injury rate were 22.9% (8/35) in the experimental group 3, significantly higher than 2.9% (1/35) in the experimental group 1 and 5.7% (2/35) in experimental group 2, the difference was statistically significant ( χ2 values were 6.248, 4.200, P<0.05). After 2 weeks of treatment, the levels of fbgrinogen and D-Dimer were (5.32±1.82) g/L, (0.71±0.38) mg/L and (4.15±1.82) g/L, (0.39±0.13) mg/L and (3.75±1.46), (0.33± 0.14) mg/L in the experimental group 1, experimental group 2, experimental group 3, respectively; the fbgrinogen and D-Dimer was significantly decreased in the experimental group 2 and experimental group 3 compared to the experimental group 1 ( t values were 2.131-3.977, P<0.05), however, there was no significant difference between experimental group 2 and experimental group 3 ( P>0.05). Conclusions:IPC can be extend to 40 min every time, twice a day, which can significantly improve coagulation function and do not increase the incidence of skin pressure injury of critical patients in respiratory department. It is worth being applied in clinic.
