Effects of wrist hand thumb joint fixtures in infants to prevent the unplanned extubation of radial artery manometric tube in children with congenital heart disease / 中国实用护理杂志

ABSTRACT

Objective:To understand clinical effect of a homemade infants wrist hand thumb joint fixtures to prevent the unplanned extubation (UEX) in radial arterial puncture tube in children with congenital heart disease.Methods:From October 2016 to October 2019, 150 cases infants patients with simple congenital heart disease in cardiac surgery of the First Affiliated Hospital of University of Science and Technology of China were selected as the research objects, and the radial artery invasive manometric tube was routinely indwelling after operation. Subjects were randomly divided into observation group and control group, with 75 cases in each group. In the observation group, the wrist joint of children was fixed with homemade fixation device. The control group used conventional fixation methods to fix the wrist joint of infants. The incidence of pressure injury and unplanned extubation were compared between the two groups.Results:There was 1 case (1.33%) pressure injury in the observation group and 2 cases (2.67%) in the control group, and there was no statistical significance in the two groups ( P>0.05). The unplanned extubation rate of radial artery pressure tube occurred in 5 cases (6.67%) in the observation group, and lower than that in the control group (17/75, 22.67%) ( χ2=7.67, P<0.01). When children in the state of agitation and very agitation, the incidence of unplanned extubation rate in the observation group was 0 and 4.35%(1/23), lower than that in the control group 15.79%(6/38) and 35.00% (7/20), respectively ( χ2=6.19, 6.64, both P<0.05). With the extension of ICU time, the incidence of unplanned extubation rate was increased. The incidence of unplanned extubation rate was 4.76% (2/42) and 9.09% (3/33) in the observation group and 18.18%(8/44) and 29.03% (9/31) in the control group when ICU time was ≤24 h and>24 h, respectively. The difference was statistically significant ( χ2=5.51, 4.17, both P<0.05). Conclusions:The homemade wrist thumb joint fixtures device for infants does not increase the pressure injury of the fixed part, and can reduce the incidence of unplanned extubation of radial artery manometric tube in children with congenital heart disease.
