What this trial studies

This interventional study aims to assess the effects of Maxigesic, a combination of acetaminophen and ibuprofen, on the incidence and severity of postoperative delirium in elderly patients undergoing minimally invasive lung surgery. Participants aged 65 and older will receive either Maxigesic or a placebo (normal saline) during the perioperative period. The study will monitor patients for 5 days post-surgery to evaluate any changes in delirium symptoms. The goal is to determine if Maxigesic can effectively reduce the occurrence of delirium in this vulnerable population.

Who should consider this trial

Good fit: Ideal candidates are patients aged 65 years or older scheduled for minimally invasive lung lobectomy or segmentectomy.

Not a fit: Patients with severe pre-existing health conditions or those with hypersensitivity to the ingredients in Maxigesic may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative outcomes and reduced incidence of delirium in elderly patients after lung surgery.

How similar studies have performed: Other studies have shown promising results with similar perioperative analgesic approaches, suggesting potential for success in this trial.
