Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Group NSS | The patients received normal saline with the same amount of magnesium sulphate for loading and continuous infusion started at skin incision until dura was closure. Anesthesia was maintained with propofol, fentanyl, cisatracurium and sevoflurane. Vasopressor or antihypertensive drug are used to control hemodynamics. | 1 | 38 | EG000 |
| Group 2 | Group Mg | The patients received 40 mg/kg of magnesium sulphate loading in 30 minutes at incision and then continuous drip 10 mg/kg/hr until dura was closure. Anesthesia was maintained with propofol, fentanyl, cisatracurium and sevoflurane. Vasopressor or antihypertensive drug are used to control hemodynamics. | 1 | 38 | EG001 |
