    PRIJEOPERACIJSKA PRIMJENA KLONIDINA ILI LEVOBUPIVAKAINA – UČINAK NA SUSTAVNI UPALNI ODGOVOR ORGANIZMA ----- Potpunom kontrolom perioperacijske boli možemo nadzirati odgovor imunosnog sustava i oslobađanje medijatora upale, čime izravno utječemo na ishod liječenja. Primjena analgetika prije nastanka bolnog podražaja (preventivna analgezija) sprječava razvoj neuroplastičnih promjena u sredi{njem živčanom sustavu, te može smanjiti razinu boli. Hipoteza istraživanja je da prijeoperacijska epiduralna primjena klonidina značajno učinkovitije blokira bol i sustavni upalni odgovor organizma u odnosu na levobupivakain. Bolesnici su razvrstani u tri skupine, obzirom na prijeoperacijsku epiduralnu primjenu klonidina, levobupivakaina ili fiziolo{ke otopine (kontrolna skupina). Prije operacije, 1 h nakon početka operacije, te 1 h, 6 h, 12 h i 24 h nakon operacije analizirani su parametri: interleukin-6, C-reaktivni protein i leukociti. Između ispitivanih skupina nije bilo statistički značajne razlike u dobi, spolu, tjelesnoj masi i trajanju operacije. U skupini s klonidinom prije operacije dokazane su statistički značajno najniže vrijednosti interleukina-6 tijekom cijelog vremena ispitivanja, u usporedbi s skupinom s levobupivakainom prije operacije i kontrolnom skupinom ispitanika. Dokazane su značajno najniže vrijednosti C-reaktivnog proteina na kraju ispitivanja, u usporedbi s druge dvije skupine ispitanika. Vrijednosti leukocita su tijekom cijelog vremena ispitivanja značajno najniže i unutar normalnih granica jedino u skupini s klonidinom prije operacije. Istraživanjem su dokazane statistički značajne razlike, koje potvrđuju važnost centralnog učinka klonidina na puteve boli i blokadu upalnog odgovora organizma.

    English abstract

    With perioperative pain control it is possible to supervise immune system, release of inflammation mediators, and influence on treatment outcome. Use of analgetics before the pain stimulus (preventive analgesia) obstruct development of neuroplastic changes in central nervous system, and reduces pain. Investigation hypothesis was that preoperative epidural clonidine is more efficient in blockade of systemic inflammatory stress response comparing to levobupivacaine. Patients were allocated to three groups, according to preoperative epidural use of clonidine, levobupivacaine or saline (control group). Before operation, 1 h after the beginning, 1 h, 6 h, 12 h and 24 h after the operation following parameters were analyzed: interleukine-6, C-reactive protein and leukocyte count. There were no significant differences between groups in age, gender, body mass index and operation time. In preoperative clonidine group, we found significant reduction in interleukine-6 levels throughout investigation time, compared to preoperative levobupivacaine group and control group. Also, C-reactive protein was significantly lower at the end of investigation, compared to other two groups. Leukocyte count was lower, and within the normal range in all investigation times only in preoperative clonidine group. We demonstrated significant difference that support importance of clonidine central effect on pain pathways and systemic inflammatory blockade.
