Abstract
NAJERA GONZALEZ, Eduardo Alberto et al. Haemodynamic variables and outcomes of renal function on intensive care patients. Med. crít. (Col. Mex. Med. Crít.) [online]. 2019, vol.33, n.4, pp.189-195. Epub July 30, 2021. ISSN 2448-8909.
Introduction:
Haemodynamic variables inform us about the progression of acute kidney injury (AKI).
Material and methods:
Prospective, observational and longitudinal study of patients admitted to Intensive Care (ICU) from 2017-2018. patients over 18 years were included, with acute kidney injury (AKI 1, 2), and hemodynamic monitoring of mean arterial blood pressure (MAP), diastolic blood pressure (DBP), heart rate (HR) and central venous pressure (CVP). Determined from 24 hours after diagnosis and its evolution was recorded until discharge.
Results:
A total of 164 patients were included, progression of AKI presented when MAP < 75.98 mmHg, DBP < 61 mmHg, CVP < 8 cmH2O, FC 90 x’, MAP-CVP 67.64 mmHg, DBP-CVP 53.28 mmHg, HR > 90 beats/minute.
Conclusions:
MAP, DBP and CVP have the greatest impact on the risk of AKI progression, especially when the mean perfusion pressure (PPM) is calculated with these two variables.
Keywords : Renal perfusion pressure; mean perfusion pressure; acute kidney injury; central venous pressure; mean arterial pressure.
