Application and nursing of positive pressure intravenous catheter in AIDS patients＇ infusion

Abstract

Objective To study the positive pressure intravenous catheter in HIV patients＇ infusion. Methods 4000 HIV out-patients from Feb 2010 to Mar 2012 were studied and divided into experimental group and control group depending on patients＇ intention for positive pressure venous catheter. 2000 cases in the experimental group were applied with positive-pressure intravenous catheter infusion. Traditional needle was used for the infusion in 2000 cases of the control group. Fluid fluency, skin lesions, phlebitis, needle injuries, and incidence of occupational exposure of the patients were observed by the responsible nurses. Results In the experimental group, 1 870 cases （93.5%） of infusion were fluent; 180 cases （9.0%） had red and swollen at the puncture site; 189 cases （9.5%） had vascular damage. No phlebitis, needle injuries and occupational exposure were observed. On the contrary, fluency, red and swollen at puncture site and vascular damage were found 1 729 （86.5%）, 250（ 12.5% ） and 235（ 11.8% ） cases respectively in the control group. 4 cases of needle injuries and occupational exposure were found in the control group. The difference between two groups was statistically significant （ χ2 = 55. 103,12. 768,5. 582,4. 004,4. 004, respectively;P 〈 0. 01 or P 〈0.05 ）. Conclusions Positive-pressure intravenous catheter provides a safe and effective infusion for AIDS patients. It avoids the pain caused by repeated puncture to patients, effectively protects blood vessels, reduces the risk of needle injuries and occupational exposure due to repeated puncture. The positive pressure intravenous catheter plays an important role in promoting the treatment of AIDS patients. Key words: AIDS; Nursing; Infusion; Positive-pressure intravenous catheter
