Administration of Ketamine to Prevent the Post-operative Pain (KETAMINE)

September 8, 2025 updated by: Institut Bergonié

Effect of Ketamine, at the Induction and Its Maintenance to Prevent the Post-operative Pain: Clinical Trial in Cancerology

The surgery of breast cancer is responsible for post-operative pain, needing in about 30% some morphine consumption; like that, the association of ketamine with general anaesthesia may decrease morphine's use and so its adverse effects. The purpose is to evaluate the analgesic effect of a receptor NMDA's antagonist ( ketamine)

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Morphine Consumption (First 48 Post-operative Hours)
Time Frame: within 48 hours following surgery
Number of participants with at least one consumption of morphine within 48 hours following surgery.
within 48 hours following surgery

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Post-operative Pain
Time Frame: 48 hours after surgery

Count of participants with post-operative pain. Pain was measured using a Visual Analog Rating Scale (VAS), ranging from 0 (no pain) to 10 (pain).

A VAS score >= 4 wwas considered as "Pain". A VAS sore <4 was considered as "No pain".

48 hours after surgery
