The Claim

A single 2 mg/kg intravenous dose of propofol does not significantly alter salivary cortisol levels in healthy children aged 3 to 12 years undergoing urologic surgery, with cortisol concentrations remaining stable from preoperative baseline through 24 hours postoperatively, except for a minor transient rise at 11:00 AM before surgery.

Description
1 study reviewed
In plain English

In healthy children aged 3 to 12 years undergoing urologic surgery, a single intravenous dose of propofol at 2 mg/kg does not change salivary cortisol levels from before surgery to 24 hours after surgery, except for a small temporary increase at 11:00 AM before the procedure.

See the scientific wording

A single 2 mg/kg intravenous dose of propofol does not significantly alter salivary cortisol levels in healthy children aged 3 to 12 years undergoing urologic surgery, with cortisol concentrations remaining stable from preoperative baseline through 24 hours postoperatively, except for a minor transient rise at 11:00 AM before surgery.

Why this might work

Propofol does not interfere with the adrenal glands' ability to make cortisol, and it does not trigger or suppress the brain's stress response system, so cortisol levels stay normal before and after surgery except for a small, natural rise just before the procedure due to the body's normal reaction to being in a hospital environment.

  1. Study: The Effects of Single-Dose Etomidate Versus Propofol on Cortisol Levels in Pediatric Patients Undergoing Urologic Surgery: A Randomized Controlled Trial

    This study found that giving kids propofol for surgery doesn’t change their stress hormone (cortisol) levels, except for a tiny, harmless spike right before surgery — so propofol is safe in that way. Unlike another drug called etomidate, which lowers cortisol a lot, propofol leaves it normal.
