Ograđeni prostori i utočišta za zbrinjavanje europskih smeđih medvjeda (Ursus arctos) ograničeni su površinom za prihvat napuštenih jedinki. Budući da je smeđi medvjed zaštićena vrsta, valja voditi brigu o broju jedinki njihove populacije. Najbolja kontrola broja jedinki u zatočeništvu je putem kirurškoga zahvata kastracije odnosno orhiektomije mužjaka zbog relativno jednostavne izvedbe zahvata. Orhiektomija četiriju mužjaka obavljena je u općoj anesteziji kombinacijom ketamin i ksilazin hidroklorida primijenjenih intramuskularno. U sva četiri medvjeda orhiektomija je obavljena zatvorenom metodom. U jednoga je primijenjena metoda dva kožna reza usporedno s mošnjičnim šavom, a u tri medvjeda preskrotalna metoda orhiektomije. U svih je primijenjena tehnika tri hemostata prilikom podvezivanja sjemenova užeta, a rane su bile sašivene resorptivnim koncem pojedinačnim čvorastim šavom. Buđenje iz anestezije bilo je uobičajenoga tijeka bez nuspojava. Zahvat je prosječno trajao 54 minute, a opća anestezija 171,5 minuta. Sve kirurške rane zacijelile su „per primam”, a oporavak je prošao bez nuspojava. Facilities for captive holding of European brown bears (Ursus arctos) are usually limited in capacity and already filled. The brown bear is a protected species, reduction of free-living population is not allowed and protection of existing numbers is requested by international conventions. The best regulation of population in captivity is by orchiectomy because of surgical simplicity and efficiency. We achieved general anaesthesia by use of a combination of ketamine hydrochloride and xylazine hydrochloride applied intramuscularly in four treated males. Surgical procedure of orchiectomy was carried out by closed method using two skin incisions parallel to raphe scroti in one bear and prescrotal incision in the remaining 3 bears. Spermatic cord was ligated by a triple clamp technique. Skin incisions were sutured by simple interrupted pattern with absorbable suture material. Recovery from general anaesthesia was without side-effects after a mean duration of 172 min. Mean surgery time was 54 min. The surgical wounds healed “per primam”.
