What this trial studies

This clinical trial investigates the effectiveness of intravenous ketorolac as a regional analgesic in patients undergoing elective unilateral lower limb orthopedic surgeries with spinal anesthesia. Participants will be randomly assigned to receive either 30 mg of ketorolac administered intravenously after tourniquet inflation or 30 mg administered 10 minutes prior to tourniquet application. The primary outcome is to assess the duration of postoperative analgesia provided by this method compared to standard analgesic protocols. All patients will also receive standard postoperative analgesia with paracetamol and diclofenac.

Who should consider this trial

Good fit: Ideal candidates are patients classified as American Society of Anesthesiologists physical status I or II, scheduled for elective unilateral lower limb orthopedic surgery with tourniquet under spinal anesthesia.

Not a fit: Patients who are pregnant, have a high body mass index, or have specific medical conditions such as allergies to ketorolac or renal diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance postoperative pain management for patients undergoing lower limb surgeries.

How similar studies have performed: Previous studies have shown the effectiveness of intravenous ketorolac in similar settings, suggesting a promising approach for pain management.
