The Claim

Salivary cortisol measurement is a feasible and reliable method for tracking the hypothalamic-pituitary-adrenal axis response to anesthesia in children aged 3 to 12 years, as demonstrated by consistent circadian patterns in healthy volunteers and clear separation of anesthetic effects in the study population.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Salivary cortisol levels accurately reflect the stress response to anesthesia in children aged 3 to 12 years, showing predictable daily rhythms in healthy children and distinct changes during anesthesia.

See the scientific wording

Salivary cortisol measurement is a feasible and reliable method for tracking the hypothalamic-pituitary-adrenal axis response to anesthesia in children aged 3 to 12 years, as demonstrated by consistent circadian patterns in healthy volunteers and clear separation of anesthetic effects in the study population.

Why this might work

When a child receives etomidate for anesthesia, it blocks a key enzyme in the adrenal glands that makes cortisol. This causes cortisol levels in the blood to drop and stay low for about a day. Since cortisol moves from the blood into saliva, the amount of cortisol in saliva also drops. This drop is clear and consistent, so measuring cortisol in saliva shows exactly how much the anesthesia affected the body's stress system.

    Scientists measured stress hormones in kids' saliva before and after surgery and found it worked well — they could tell which anesthesia drug lowered stress hormones and when, without any problems.
