This study was undertaken to assess stress hormones response after awake videoassisted thoracoscopic surgery (VATS). Plasma levels of adrenal-corticotropic hormone (ACTH), cortisol, epinephrine, norepinephrine, and glucose were assessed at baseline, 3 h postoperatively (T1), and on postoperative mornings 2 (T2) and 3 (T3) in 21 patients undergoing awake VATS with epidural anesthesia for non-malignant conditions (n=11) or equivalent procedures performed with general anesthesia. Epinephrine level peaked in both groups at T1, although significant change from baseline values occurred in the control group only [median-Delta: 6 ng/l (IQR: 4-6), P=0.005]. Cortisol level was lower in the study group at T1 (15.5 microg/dl vs. 23.0 microg/dl, P=0.001) and T2 (15.2 microg/dl vs. 19.2 microg/dl, P=0.002). In the control group, peak cortisol level proved not to be related to changes in ACTH (R=0.23, P=0.46). At T2, glucose (137 mg/dl vs. 98 mg/dl, P=0.01) and C-reactive protein (P=0.04) were higher in the control group. No other clinically relevant between-groups differences were found in aspecific acute-response factors. Overall, these preliminary findings suggest attenuated stress response after awake VATS in comparison with equivalent procedure performed under general anesthesia and one-lung ventilation.

Abstract
This study was undertaken to assess stress hormones response after awake videoassisted thoracoscopic surgery (VATS). Plasma levels of adrenal-corticotropic hormone (ACTH), cortisol, epinephrine, norepinephrine, and glucose were assessed at baseline, 3 h postoperatively (T1), and on postoperative mornings 2 (T2) and 3 (T3) in 21 patients undergoing awake VATS with epidural anesthesia for non-malignant conditions (n=11) or equivalent procedures performed with general anesthesia. Epinephrine level peaked in both groups at T1, although significant change from baseline values occurred in the control group only [median-Delta: 6 ng/l (IQR: 4-6), P=0.005]. Cortisol level was lower in the study group at T1 (15.5 microg/dl vs. 23.0 microg/dl, P=0.001) and T2 (15.2 microg/dl vs. 19.2 microg/dl, P=0.002). In the control group, peak cortisol level proved not to be related to changes in ACTH (R=0.23, P=0.46). At T2, glucose (137 mg/dl vs. 98 mg/dl, P=0.01) and C-reactive protein (P=0.04) were higher in the control group. No other clinically relevant between-groups differences were found in aspecific acute-response factors. Overall, these preliminary findings suggest attenuated stress response after awake VATS in comparison with equivalent procedure performed under general anesthesia and one-lung ventilation.File | Dimensione | Formato | |
