BackgroundAnesthetic technique affects the neuroendocrine stress response to surgery. In this retrospective study, we compared the neuroendocrine stress response in patients undergoing endoscopic transsphenoidal pituitary adenoma surgery (ETSPAS) with total intravenous anesthesia (TIVA) with propofol-remifentanil or balanced anesthesia (BAL) with sevoflurane-remifentanil.Materials And MethodsEighty-nine patients undergoing ETSPAS were anesthetized with either propofol-remifentanil (TIVA group, n=62) or sevoflurane-remifentanil (BAL group, n=27). Data were retrospectively collected regarding preoperative and immediate postoperative serum levels of adrenocorticotropic hormone (ACTH) and cortisol (primary outcome measures), as well as other pituitary hormones and their target organ hormones (secondary outcome measures).ResultsThere were no significant differences in preoperative pituitary hormone levels between the 2 groups. The immediate postoperative ACTH (89.5 [62.1 to 162.6] vs. 256.0 [92.0 to 570.7] pg/mL; P<0.001) level was lower in the TIVA group than in the BAL group, whereas immediate postoperative cortisol levels were similar between the 2 groups. The immediate postoperative thyroid-stimulating hormone (1.85 [1.21 to 2.98] vs. 1.21 [0.44 to 1.71] μIU/mL; P=0.003), triiodothyronine (91.0 [82.0 to 103.0] vs. 69.1 [64.6 to 76.2] ng/dL; P<0.001), luteinizing hormone (2.2 [1.2 to 4.0] vs. 1.0 [0.5 to 2.3] mIU/mL; P=0.005), and prolactin (22.6±15.8 vs. 12.8±10.2 ng/mL; P=0.005) levels were higher in the TIVA group compared with the BAL group. In both groups, none of the patients who had sufficient preoperative ACTH without hydrocortisone supplementation (n=15) showed hypocortisolism in the immediate postoperative measurement.ConclusionsCompared with BAL, TIVA resulted in reduced release of ACTH and increased release of thyroid-stimulating hormone, triiodothyronine, luteinizing hormone, and prolactin in patients undergoing ETSPAS.Copyright © 2019 Wolters Kluwer Health, Inc.
