Association Between Plasma Neurofilament Light Concentration and Postoperative Delirium After Cardiac Surgery

J Cardiothorac Vasc AnesthPublished Prospective observational study

Authors' conclusion

Preoperative plasma NFL concentration was associated with POD, whereas changes in NFL were not.

Study context

Population
Patients aged ≥65 years scheduled for elective cardiac surgery with CPB
Participants
151 patients
Exposure
Perioperative plasma NFL concentration and postoperative delirium (POD)
  • PODn = 60
Outcome
Association of log(NFL) with POD
Methodological detailssingle-centre, Plasma NFL measured at induction and 6 hours postoperatively
  • Single-centre
  • Plasma NFL measured at induction and 6 hours postoperatively

Main finding

As reported in the abstract

  • Baseline and postoperative log(NFL) significantly associated with delirium
  • Perioperative changes in NFL not associated with delirium
  • Baseline log(NFL) remained an independent predictor of POD in multivariable analysis

Observational data: associations, not effects.

Further findings

Incidence of POD · 7 days

Delirium occurred
60 (40%)

Perioperative changes in NFL and POD

Perioperative changes in NFL not significantly associated with delirium

Clinical factors associated with POD

POD associated with congestive HF, lower educational status, more erythrocyte transfusion, complex procedures, prolonged deep anesthesia and intraoperative burst suppression
