BACKGROUND: For aSAH patients with external ventricular drainage (EVD) because of hydrocephalus, the consensus on application of CSF drainage from the lumbar cistern is mixed owing to concerns about its safety and questionable effectiveness. This study evaluated the additional effectiveness of CSF drainage from the lumbar cistern in aSAH patients with EVD.
METHODS: This was a retrospective and observational study of adult patients with aSAH who were admitted to the intensive care unit at the Wuhan Union Hospital between June 2018 and June 2019. Three aSAH patients with EVD and serial lumbar punctures (LPs) were selected for comparison of CSF components. Four more aSAH patients who underwent divergent CSF drainage were selected to profile the additional effectiveness of lumbar cistern drainage in aSAH patients with EVD.
RESULTS: Cases 1-3 with EVD and serial LPs showed dramatically higher red blood cell (RBC) and leukocyte counts with steeper changing curve in the lumbar cistern CSF than in the ventricle CSF. Case 5 had EVD alone and showed a slower clearing rate of blood clot in subarachnoid space compared with case 1. Case 4, with serial LPs alone, showed a steep changing curve of both RBC and leukocyte counts in the lumbar cistern CSF. Cases 6 and 7, with EVD and follow-up LPs, showed dramatically higher RBC and leukocyte counts in the lumbar cistern CSF than in the ventricle CSF after almost 2 weeks of EVD.
CONCLUSIONS: For aSAH patients with EVD, serial LPs can accelerate clearance of toxic products from the subarachnoid space.
