Hypothalamic-pituitary-adrenocortical function after the dexamethasone-promethazine adhesion regimen

Area of Science:

• Reproductive Medicine
• Endocrinology

Background:

• Dexamethasone and promethazine are common antiadhesion treatments in infertility surgery.
• Concerns exist regarding dexamethasone's potential to suppress the hypothalamic-pituitary-adrenal (HPA) axis.

Purpose of the Study:

• To evaluate the short-term impact of a dexamethasone-promethazine regimen on HPA axis function in women undergoing infertility surgery.

Main Methods:

• Twenty-five healthy women received dexamethasone and promethazine for 48 hours around surgery.
• Insulin hypoglycemia testing was conducted on postoperative day 6 to assess cortisol response.

Main Results:

• 19 out of 21 women demonstrated a normal cortisol rise (≥7 µg/dL) after insulin hypoglycemia.
• Two women exhibited an inadequate cortisol response despite adequate hypoglycemia, suggesting potential HPA axis suppression.

Conclusions:

• The dexamethasone-promethazine regimen may cause short-term HPA axis suppression in some patients.
• Close postoperative supervision is recommended for women receiving this treatment regimen.
