inhalant anesthesia) |
Moderate sedation at low

ANESTHESIA |
|
|
Telazol® |
1-5 mg/kg IM |
Sedation at low doses,
anesthesia at high doses Poor muscle relaxation,
intubation difficult Prolonged recovery at high
doses (link to video) |
Xylazine Telazol® |
0.5-2.2 mg/kg IM 3-6 mg/kg IM |
Anesthesia with good
analgesia and muscle relaxation.
Intubation possible. Apnea may
occur. |
Telazol® Ketamine } TKX Xylazine |
4.4 mg/kg IM 2.2 mg/kg IM 2.2 mg/kg IM IV (for induction prior to inhalant anesthesia)
– give slowly (over 1min) to reduce respiratory depression |
Reconstitute powdered
Telazol® with 250mg xylazine (2.5ml) and 250mg ketamine (2.5ml). Dose at 1ml/25-35kg (use 1
ml/ 75kg for IV induction) Intubation possible, apnea

Mix to final concentration
of 50mg/ml guafenesin, 2 mg/ml ketamine
and 1 mg/ml xylazine Good for Cesearian sections because piglets are only minimally
depressed |
Propofol |
IV infusion Induction: 2-5 mg/kg CRI : 4-8 mg/kg/hr |
Rapid onset, short
