The Effect of Changes in Postural Position Angle Degree on Central Venous Pressure Measurement

Abstract

Background: Central venous pressure is often used in intensive care, especially in patients who ex\xadpe\xadrience impaired fluid balance, heart failure, evaluation of therapeutic response and media for the\xad\xadrapy or hypertonic fluid. The patient s hemodynamic condition during treatment in the intensive care unit (ICU) is con\xad\xadstantly changing (unstable), therefore, serial monitoring of central venous pressure is needed and the patient s position must be constant. Changing the position of the patient in a place is some\xadti\xad\xadmes something that cannot be avoided when the patient is in intensive room. This study aimed to examine the effect of changing the position of patients in bed at 0 0 , 15 0 , 30 0 , and 45 0 on central venous pressure (CVP) va\xadlues. Subjects and Method: This was quasi-experimental study, using a post test with\xadout control group with repeated measures. This study was conducted in the ICU/ICCU Room at Tarakan Ho\xads\xadpital, No\xadrth Kalimantan, from May to June 2019. A total of 30 patients was selected by acci\xadden\xad\xad\xadtal sampling. The dependent variable was central venous pressure. The independent variable was the position of the patient when a central venous pressure examination was carried out, with the degree of positions which were 0 0 , 15 0 , 30 0 , and 45 0 . The data was obtained from observation she\xadet. CVP was measured by water manometer. The data were analyzed by Anova. Results: The lowest mean CVP was achieved at 0o (Mean=15.13; SD= 5.79). The highest mean CVP was achieved at 45o (Mean=18.18; SD=5.35). The different mean between 0o and 45o was sta\xadtis\xadtically significant (p=0.001). The mean CVD at 15o was mean=16.35; SD=5.73. The mean CVD at 30o was mean=17.07; SD=5.42). The different mean between 15o and 30o was statistically sig\xadni\xadfi\xadcant (p=0.047). Conclusion: The best position for perform central venous pressure is 45 o . Keywords: \xa0central vein pressure, intensive care, patient position Correspondence:\xa0 Hendy Lesmana.
