Groups2
Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Vasopressin and Methylprednisolone | The study drugs will consist of 40 mg methylprednisolone (Solu-medrol®, Pfizer) and 20 IU of vasopressin (Empressin®, Amomed Pharma GmbH) given as soon as possible after the first dose of adrenaline. Additional doses of vasopressin (20 IU) will be administered after each adrenaline dose for a maximum of four doses (80 IU).~Vasopressin, Arginine: 20 IE of vasopressin per dose for a maximum of four doses (80 IU)~Methylprednisolone: 40 mg methylprednisolone once | 18 | 237 | OG000 |
| Group 2 | Placebo | The placebo for vasopressin will consist of 1 mL of 9 mg/mL NaCl (normal saline) from 2 mL ampules identical to the vasopressin ampules. The placebo for methylprednisolone will also consist of 1 mL of 9 mg/mL NaCl.~NaCl: Placebo | 20 | 264 | OG001 |
