Effects of two indwelling needles with different materials on catheterization-associated complications and comfort of cerebral angiography patients / 中国实用护理杂志

ABSTRACT

Objective:To explore the effects of two kinds of indwelling needles with different materials on catheterization related complications and comfort of patients undergoing cerebral angiography.Methods:A total of 120 patients who were hospitalized in Neurology Department of Qinhuangdao First Hospital and were given venous indwelling needles for intravenous infusion from July 2018 to May 2019 were randomly enrolled. According to admission order, they were numbered and divided into observation group and control group by random number table method, 60 cases in each group. The control group was given common intravenous indwelling needle, while observation group was given indwelling needle of positively pressurized needle-free link-reservation. The differences in catheterization related complications, catheterization time and comfort were compared between the two groups.Results:At 24 h after catheterization, the incidence rates of tube blockage, fluid exudation and phlebitis in observation group were 0, 1.67% (1/60), 0, while 3.33% (2/60), 3.33% (2/60), 3.33% (2/60) in control group, there were no significant differences between the two groups ( χ2 values were 2.037, 0.348, 2.039, P> 0.05). At 48 h after catheterization, the incidence rates of tube blockage, fluid exudation and phlebitis in observation group were 1.67% (1/60), 1.67% (1/60), 1.67% (1/60), while 10.00% (6/60), 8.33% (5/60), 6.67% (4/60) in control group, there were no significant differences between the two groups ( χ2 values were 3.793, 2.814, 1.884, P>0.05). At 72 h after catheterization, the incidence rates of tube blockage, fluid exudation and phlebitis in observation group were all 3.33% (2/60), which were lower than 16.67% (10/60), 15.00% (9/60), 13.33% (8/60) in control group, there were significant differences between the two groups ( χ2 values were 5.934, 4.905, 3.937, P<0.05). At 24, 48 and 72 h after catheterization, liquid flow rates per unit of time before and after tube flashing in observation group were (506.15 ± 66.84), (483.55 ± 36.87), (410.62 ± 41.66) ml/h, which were higher than (474.77 ± 45.71), (417.80 ± 22.14), (310.87 ± 20.96) ml/h in control group ( t values were 3.002, 11.842, 16.568, P<0.05). The comfort score was (8.53 ± 1.41) points in observation group, higher than (7.97 ± 1.23) points in control group, and indwelling time of indwelling needles was (84.45 ± 8.95) h in observation group, longer than (76.97 ± 6.77) h in control group ( t values were 2.318, 5.163, P<0.05). Conclusions:Indwelling needle of positively pressurized needle-free link-reservation can effectively reduce incidence of complications in patients undergoing cerebral angiography, and improve their comfort during catheterization.
