Oral ketamine versus oral clonidine to calm children before elective lower abdominal day-case surgery

Premedication in Children: a Clinical Trial Comparing Oral Ketamine and Oral Clonidine With Respect to Sedation Level and Opioid Consumption in Pediatrics Undergoing Elective Lower Abdominal Day-case Surgery.

Not applicable Interventional Cairo University · NCT07461376

We will test whether a single dose of oral ketamine or oral clonidine given before elective lower abdominal day-case surgery helps children be calmer and reduces the need for opioid pain medicines.

What this trial studies

This interventional trial enrolls children aged 3–12 years (ASA I–II) having elective lower abdominal day-case operations and gives one group oral ketamine and the other oral clonidine as premedication. Sedation level is measured before and after surgery and intraoperative opioid consumption is recorded to compare the two drugs. Children with significant cardiac, respiratory, neurologic disease or drug allergies are excluded. The trial is conducted at the Faculty of Medicine, Cairo University and uses standard anesthesia and monitoring protocols.

Who should consider this trial

Good fit: Children aged 3 to 12 years, ASA I–II, scheduled for elective lower abdominal day-case surgery (for example inguinal herniorrhaphy, hypospadias repair, or circumcision) whose parents consent and who have no major cardiac, respiratory, neurologic disorders or drug allergies.

Not a fit: Children with ASA score > II, significant heart/lung/neurologic disease, known allergy to the study drugs, or those having other types of surgery are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could identify a premedication that reduces preoperative anxiety and lowers intraoperative opioid requirements for children undergoing these procedures.

How similar studies have performed: Prior pediatric research shows clonidine reliably produces preoperative sedation and can reduce anesthetic and opioid needs while ketamine is established for sedation and analgesia, though direct head-to-head comparisons in this exact setting have been limited.
