abstract = "Background: Surgical stress and pain result in activation of hypothalamus-pituitary-adrenal axis. The aim of this study was to establish the effects of postoperative pain and various modalities of analgesic administration on salivary and serum cortisol levels, as well as to establish the validity of salivary cortisol as a stress indicator in surgical patients. Methods: A randomized controlled trial involved 60 patients scheduled for elective abdominal aortic aneurysm surgery. Patients were randomly divided into two groups depending on the model of postoperative analgesia. The first group (MI – morphine intermittently) included patients given morphine doses 0.1 mg/kg/6h s.c. intermittently. The second group (MPCA – morphine patient-controlled analgesia) included patients who received morphine via the PCA system – intravenous administration of morphine adjusted to a dose of 1 mg per shot and a lockout interval of 6 minutes. Results: The intensity of pain did not significantly vary until the hour 10 post-surgery. However, in the period from hour 10 to hour 18 post-surgery, higher intensity of pain was reported in group MPCA (P < 0.05). Hemodynamic instability was more prevalent in the MI group (40.0% vs 6.7%, P = 0.0048). Serum cortisol levels were almost identical in both groups (MI 509.4 nmol/L vs MPCA 511.0 nmol/L, P = 0.1473). Higher values of salivary cortisol were recorded in group MPCA; however, the difference was not statistically significant (47.1 nmol/L vs 116.3 nmol/L, P = 0.0970). Conclusion: Our study confirmed that salivary cortisol is a more sensitive stress biomarker in surgical patients as compared to blood cortisol., Uvod: Hirur{ki stres i bol su uzrok aktivacije hipotalamus- no-hipofizno-nadbubre`ne osovine. Cilj ove studije bio je da se utvrdi uticaj postoperativnog bola i razli~itih vidova administracije analgetika na vrednosti kortizola u serumu i salivi, kao i da se utvrdi da li je salivarni kortizol dobar poka- zatelj stresa kod hirur{kih pacijenata. Metode: Randomizovana kontrolisana studija koja je uklju- ~ila 60 pacijenata primljenih za elektivnu operaciju ane- urizme abdominalne aorte. Pacijenti su metodom slu~ajnog izbora podeljeni u dve grupe u zavisnosti od modela post- operativne analgezije. Prvu grupu (MI – intermitentna pri- mena morfina) su ~inili pacijenti koji su dobijali morfin intermitentno u dozi od 0.1 mg/kg/6h s.c. U drugoj grupi (MPCA – analgezija morfinom kontrolisana od strane paci- jenta) su bili pacijenti koji su dobijali morfin takozvanom PCA metodom – intravenska primena morfina 1 pritisak/1 mg, interval 6 minuta. Rezultati: Intenzitet bola se nije zna~ajno razlikovao do desetog sata nakon operacije. Me|utim, u periodu od de- setog do osamnaestog sata nakon operacije bol je bio izra`eniji u MPCA grupi (P < 0.05). Hemodinamska nesta- bilnost je bila zastupljenija u grupi MI (40.0% vs 6.7%, P = 0.0048). Serumski kortizol bio je gotovo identi~an po gru- pama (MI 509.4 nmol/L vs MPCA 511.0 nmol/L, P = 0.1473). Salivarni kortizol je bio vi{i u grupi MPCA ali razika nije statisti~ki zna~ajna (47.1 nmol/L vs 116.3 nmol/L, P = 0.0970). Zaklju~ak: Na{a studija je pokazala da je salivarni kortizol senzitivniji biomarker stresa kod hirur{kih pacijenata u odnosu na serumski kortizol.",
