Cohorts and Interventions

Group / Cohort
Intervention / Treatment
High Sampling Rate
Samples will be obtained at a high rate
Both cohorts will have a lumbar catheter placed and CSF samples will be obtained. The only difference between the two arms will be the sampling rate of CSF. One arm will have a high sampling rate and the other will have a low sampling rate.
Low Sampling Rate
Samples will be obtained at a low rate
Both cohorts will have a lumbar catheter placed and CSF samples will be obtained. The only difference between the two arms will be the sampling rate of CSF. One arm will have a high sampling rate and the other will have a low sampling rate.
