BACKGROUND: We sought to determine whether a pilot goal-directed perfusion
initiative could reduce the incidence of acute kidney injury after cardiac
surgery. METHODS: On the basis of the available literature, we identified goals
to achieve during cardiopulmonary bypass (including maintenance of oxygen
delivery >300 mL O2/min/m(2) and reduction in vasopressor use) that were combined
into a goal-directed perfusion initiative and implemented as a quality
improvement measure in patients undergoing cardiac surgery at Johns Hopkins
during 2015. Goal-directed perfusion initiative patients were matched to controls
who underwent cardiac surgery between 2010 and 2015 using propensity scoring
across 15 variables. The primary and secondary outcomes were the incidence of
acute kidney injury and the mean increase in serum creatinine within the first
72 hours after cardiac surgery. RESULTS: We used the goal-directed perfusion
initiative in 88 patients and matched these to 88 control patients who were
similar across all variables, including mean age (61 years in controls vs
64 years in goal-directed perfusion initiative patients, P = .12) and
preoperative glomerular filtration rate (90 vs 83 mL/min, P = .34). Controls
received more phenylephrine on cardiopulmonary bypass (mean 2.1 vs 1.4 mg,
P < .001) and had lower nadir oxygen delivery (mean 241 vs 301 mL O2/min/m(2),
P < .001). Acute kidney injury incidence was 23.9% in controls and 9.1% in
goal-directed perfusion initiative patients (P = .008); incidences of acute
kidney injury stage 1, 2, and 3 were 19.3%, 3.4%, and 1.1% in controls, and 5.7%,
3.4%, and 0% in goal-directed perfusion initiative patients, respectively.
Control patients exhibited a larger median percent increase in creatinine from
baseline (27% vs 10%, P < .001). CONCLUSIONS: The goal-directed perfusion
initiative was associated with reduced acute kidney injury incidence after
cardiac surgery in this pilot study.
