Is this trial a fit for you?

Likely a good fit

Children aged 3–12 years with cancer, ASA class I–III, scheduled for elective abdominal surgery under general anesthesia, who are not allergic to nalbuphine or tramadol and are not on chronic opioids.

Probably not a fit

Children outside the 3–12 age range, those allergic to either drug, those already using chronic opioids, or those having emergency procedures are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Children with cancer aged 3–12 who are scheduled for elective abdominal surgery under general anesthesia will receive either nalbuphine or tramadol for postoperative pain management. Investigators will monitor pain scores and common opioid-related side effects such as respiratory depression, nausea/vomiting, and pruritus in the immediate postoperative period. Patients with allergies to the study drugs or on chronic opioid therapy are excluded. The goal is a direct comparison of analgesic effectiveness and safety between the two drugs in this surgical pediatric population.

Why it matters

Potential benefit: If successful, this could identify which opioid provides better pain relief with fewer side effects for children with cancer after abdominal surgery.

How similar studies have gone: Prior adult studies and some pediatric reports show tramadol provides effective analgesia with comparatively fewer adverse effects, but direct head‑to‑head pediatric comparisons with nalbuphine after abdominal surgery are limited.
