Rigamonti, S M; Bettschart-Wolfensberger, Regula; Schwarz, Andrea; Nussbaumer, Iwan (2018). Ermittlung eines feldtauglichen Injektionsanästhesieprotokolls zur Kastration von 8 bis 14-tägigen Ferkeln. Schweizer Archiv für Tierheilkunde, 160(7-8):469-474.

Abstract

The aim of this study was to find an intramuscularly (IM) injectable anaesthetic combination for 8 to 14-days old piglets, that guarantees a calm induction and sufficient quality of anaesthesia without excitations with a maximum of two hours long lasting recovery. In preliminary dose finding trials, different combinations of ­ketamine, azaperone and romifidine were compared. A constant dose of 0.2 mg/kg of butorphanol was added to each combination and all piglets received 0.4 mg/kg meloxicam. Subsequently a dosage algorithm for the main trial was developed. In case of insufficient analgesia, lidocaine 2% (0.25 ml) was injected intratesticular. If two piglets showed an insufficient anaesthetic induction phase, depth of anaesthesia or recovery, the next dosage in the algorithm was tried. With the combination of 3 mg/kg azaperone, 0.2 mg/kg romifidine, 15 mg/kg ketamine and 0.2 mg/kg butorphanol the requirement of a smooth anaesthesia induction, sufficient anaesthesia and a recovery without excitation was fulfilled but the recovery lasted more than 120 minutes.
