Is this trial a fit for you?

Likely a good fit

Adults aged 60 years or older with ASA I–III scheduled for elective hip surgery under spinal anesthesia.

Probably not a fit

Patients with severe cardiac disease, uncontrolled hypertension, contraindications to spinal anesthesia, or other exclusion criteria may not benefit.

What this trial studies

This is a prospective, randomized, double-blinded study enrolling elderly patients (60 years and above) scheduled for elective hip surgery under spinal anesthesia. Participants will be assigned to receive prophylactic norepinephrine infusion or phenylephrine infusion immediately after spinal block, with primary outcome focusing on heart rate during vasopressor infusion. Secondary outcomes include incidence of hypotension, severe hypotension, bradycardia, reactive hypertension, intraoperative fluid needs, blood loss, transfusion requirements, and postoperative nausea and vomiting. The study aims to compare hemodynamic stability and safety between the two vasopressor strategies in an older population with ASA I–III status, conducted at Sohag University Hospitals after ethics approval.

Why it matters

Potential benefit: If successful, this approach could improve hemodynamic stability and reduce perioperative complications for elderly patients undergoing hip surgery under spinal anesthesia.

How similar studies have gone: Previous studies have explored vasopressors for spinal anesthesia-induced hypotension, with mixed results; this study adds randomized, blinded data in an elderly hip-surgery population.
