title: Effect of Intramuscular Adrenaline on Histamine‐Induced Hypotension: A Randomised Placebo‐Controlled Pilot Trial

description: Data from: Effect of Intramuscular Adrenaline on Histamine‐Induced Hypotension: A Randomised Placebo‐Controlled Pilot Trial

Description of the data and file structure

Clinical and demographic data on subjects challenged with intravenous histamine (0.25 to 1 µg/kg/min) for 15 minutes; includes pharmacological intervention data from intramuscular adrenaline/epinephrine and placebo periods where applicable.

Files and variables

File: EPI-HIS_Dataset_Zenodo.xlsxDescription: This Excel workbook contains two Sheets, one for hemodynamic and laboratory parameters and one for adverse events.

Variables

Sheet: EPI_HIS_Dataset  - Subject_ID — individual ID  - Periode — treatment period (0 = Screening/Baseline, 1-4 = different interventional periods)  - Time — minutes relative to start of histamine infusion (= 0 min)  - Intervention — Intervention of respective period (Dose-finding, Adrenaline, Fluids, Leg-Elevation) [see study protocol for interventional procedure]  - Responder — individual with any single timepoint >60 mmHg MAP after adrenaline/Placebo application  - Adrenaline_Dose — in µg  - HIS-dose — in µg/kg/min  - Exploratory_Confirmatory — part of study  - PR_b/min — bpm  - delta-PR — Delta: value at time t minus baseline; baseline = subject- and period-specific average during −10 to −0.33 min before time zero (t = 0)  - SYS_mmHg — systolic blood pressure in mmHg  - delta-SYS — Delta: value at time t minus baseline; baseline = subject- and period-specific average during −10 to −0.33 min before time zero (t = 0)  - DIA_mmHg — diastolic blood pressure in mmHg  - delta-DIA — Delta: value at time t minus baseline; baseline = subject- and period-specific average during −10 to −0.33 min before time zero (t = 0)  - MAP_mmHg — mean arterial pressure in mmHg  - delta-MAP — Delta: value at time t minus baseline; baseline = subject- and period-specific average during −10 to −0.33 min before time zero (t = 0)  - adrenaline_concentration — plasma adrenaline concentration in pg/mL  - histamine_concentration — plasma histamine concentration in ng/mL  - Hemoglobin — g/dL  - Hematocrit — %  - PLT — platelets ×10^9/L  - WBC — white blood cells ×10^9/L  - Creatinine — mg/dL  - BUN — Blood urea Nitrogen mg/dL  - ALP — Alkaline phosphatase U/L  - AST — Aspartate aminotransferase U/L  - ALT — Alanine aminotransferase U/L  - GGT — Gamma-glutamyl transferase U/L  - LDH — Lactate dehydrogenase U/L  - CRP — C-reactive protein mg/dL  - Tryptase — µg/L (≙ ng/mL)  - Lactate — mmol/L  - CystatinC — mg/L  - Age — ranges (decades)  - Sex — male/female (self-reported)  - BMI — kg/m^2

Sheet: EPI_HIS_Adverse_Events  - Subject-ID — individual ID  - Period — treatment period (0 = Screening/Baseline, 1-4 = different interventional periods)  - Adverse Event   - duration — duration in min from beginning of adverse event  - Severity — (mild = 1, moderate =2, severe = 3)  - Dose change — change of histamine dose due to adverse event  - ConMed — Administration of concomitant medication due to adverse event  - Relationship — 1=definitely, 2=probably, 3=possible, 4=unlikely, 5=not related
