What this trial studies

Adults 18–75 scheduled for thyroidectomy at Sohag University Hospital will be assigned to receive a perioperative infusion of lidocaine, ketamine, or saline and postoperative pain outcomes will be compared. The protocol excludes patients with toxic goiter, hyperthyroidism, BMI over 30, uncontrolled hypertension, severe liver or kidney disease, or known allergies to the study drugs. Pain scores, analgesic (including opioid) consumption, and adverse events will be recorded after surgery to measure effectiveness and safety. This single-center interventional trial aims to identify which infusion provides better pain relief and potentially reduces opioid needs after thyroidectomy.

Who should consider this trial

Good fit: Adults aged 18–75 of either sex scheduled for thyroidectomy who do not have toxic goiter, hyperthyroidism, BMI over 30, uncontrolled hypertension, severe liver or kidney disease, or allergies to lidocaine or ketamine.

Not a fit: Patients with toxic goiter or hyperthyroidism, BMI >30, uncontrolled hypertension, severe liver or kidney disease, or allergy to the study drugs are excluded and would not be eligible to participate or benefit.

Why it matters

Potential benefit: If successful, one of the infusions could lower postoperative pain and reduce opioid use after thyroidectomy.

How similar studies have performed: Previous studies in various surgical populations have shown that IV lidocaine and low‑dose ketamine can reduce postoperative pain and opioid requirements, but direct comparisons specifically in thyroidectomy are limited.
