Abstract
Lidocaine and prilocaine stabilize the neuronal membranes inhibiting the flow of natrium ions and induce a biphasic vascular response, when initial vasoconstriction is followed by vasodilation. Mixture of lidocaine/prilocaine has been used successfully for topical anaesthesia in veterinary medicine. The aim of this study was evaluation of the practical use of lidocaine/prilocaine as the local anaesthetics for surgical treatment of prolapsed penile in male chelonians. Eighteen males of chelonians were included to this study; 14 chelonians with acute penile prolapse and 4 males with chronic penile prolapse. Systemic analgesia has been induced by NSAIDs and opioids. The prolapsed penis was cleaned of debris with saline wash and lidocaine/prilocaine cream was administered topically on its mucosa. The time interval from lidocaine/prilocaine administration to loss of hind limbs withdrawal reflex and response to penile mucosa pinching was recorded as induction time for surgical anaesthesia, and it was 19.22 ± 4.36 minutes. The time interval from lidocaine/prilocaine administration to full recovery of tail and hind limbs withdrawal reflex and response to pinching was recorded as the recovery time, and it was 40.83 ± 7.68 minutes. In all 18 male chelonians the surgical treatment of prolapsed penile was uneventful. Topical administration of lidocaine/prilocaine cream can be recommended as a feasible form of local anaesthesia for the minor surgical procedures in chelonians.
