- Data shown as n (%). Cohort 1: immediate sampling, high frequency; cohort 2: delayed sampling, high frequency, procedure effect; cohort 3: ibuprofen, high frequency, inflammation effect; cohort 4: immediate sampling, low frequency
- The laboratory parameters (clinical chemistry, hematology, urinalysis) were evaluated at screening, on days –1 and 2, and during follow-up (days 7–14 after removal of the spinal catheter). The vital signs and resting 12-lead ECGs were evaluated at screening, on days –1, 1, and 2, and during follow-up. The participants were physically and neurologically examined at screening, on days 1 and 3, and in follow-up. Fundoscopy was performed at screening to exclude intracranial pressure
