A "champagne tap" is a lumbar puncture with no cerebrospinal fluid (CSF) red blood cells (RBCs). Clinicians disagree whether the absence of CSF white blood cells (WBCs) is also required. ⋯ In infants, a lumbar puncture with a CSF RBC count of 0 cells/mm3 regardless of the CSF WBC count occurred eight-times more frequently than one with both CSF WBC and RBC counts of 0 cells/mm3 . A broader champagne tap definition would allow more frequent recognition of procedural success, with the potential to foster a supportive community during medical training, potentially protecting against burnout.
