Safe and effective anaesthesiological protocols in domestic pig.The aim of this study was to establish a neuroleptanalgesic protocol anda general anaesthetic protocol in domestic pigs. The study was approved by approved by the Local Ethical Commission of the University of Warmia and Mazury in Olsztyn (the permit no. 73/2015). Fifteen juvenile female crossbred gilts were used. The drugs used in intramuscularly injection were: atropine (0.035 mg/kg b.w.), ketamine (7.0 mg/kg b.w.), medetomidine (0.063 mg/kg b.w.). The main anaesthetic drug, propofol, was given intravenously for induction and maintenance of general anaesthesia. To achieve the adequate neuroleptanalgesia the animals required in intramuscular injection atropine, ketamine and medetomidine mixing in the same syringe. The average time from muscular injection to the point at which pigs remained laterally recumbent was 1.95 ± 0.72 min. The average time from muscular injection to the point at which pigs managed to stand in recovery was 75.80 ± 13.14 min. To achieve the general anaesthesia the pigs required atropine, ketamine, medetomidine and propofol. Premedication with mixture of atropine, ketamine and medetomidine was achieved rapidly after intramuscular injection. All pigs became recumbent within 1.20 ± 0.19 min without any signs of excitement. The average time from muscular injection to the point at which pigs remained laterally recumbent was 2.06 ± 0.67 min. The induction dose of propofol was 4.5 mg/kg b. w.. Anaesthesia was maintained with propofol 2.0 mg/kg b.w.. During the surgery no complications occurred intraoperatively concerning. Concluding the findings demonstrate that the proposed protocols permits to obtain a safe and effective neuroleptanalgesia and general anaesthesia in swine and can be useful in biomedical investigations. A short-lasting time for recumbency after intramuscularly injection of atropine, ketamine and medetomidine mixture injection can allow optimizing the workflow of clinical practice in a laboratory animal farm.
