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 | Regional Anesthesia | Approximately half of the subjects will be randomized to the arm which receives Regional Anesthesia.~Regional Anesthesia: Regional anesthesia involves temporarily numbing parts of the body with nerve blocks. Spinal anesthesia is a type of regional anesthesia that uses medications injected into the fluid surrounding the spinal cord to temporarily numb the legs and lower abdomen. Spinal anesthesia is the most widely used type of regional anesthesia for hip fracture surgery. While intravenous sedation is typically used for comfort with spinal anesthesia, invasive airway interventions are not typically required. | 132 | 712 | OG000 |
| Group 2 | General Anesthesia | Approximately half of the subjects will be randomized to the arm which receives General Anesthesia.~General Anesthesia: General anesthesia uses injected or inhaled medications to keep people unconscious during surgery. Since general anesthesia depresses breathing and impairs protective airway reflexes, invasive airway interventions such as breathing tube placement and mechanical ventilation are usually required. | 132 | 733 | OG001 |
