11.5 - Species Information: Guinea Pig


GUINEA PIG (Cavia porcellus)

Physiologic Parameters

Body temperature = 37.2-39.5oC
Heart rate = 230-380/min
Respiratory rate = 42-104/min
Tidal volume = 2.3-5.3 ml/kg

Large cecum can act as reservoir for anesthetics. Depending on drug solubility, the cecum can alter the pharmacologic effect.

Induction of anesthesia using volatile anesthetics (e.g., halothane and isoflurane) should be done with caution due to initial breath holding when animals are first exposed to irritating gas vapors.

11.4 - Species Information: Hamster


HAMSTER (Mesocricetus auratus)

Physiologic Parameters

Body temperature = 37-38oC
Heart rate = 250-500/min
Respiratory rate = 35-135/min
Tidal volume = 0.6-1.4 ml
Syrian or golden hamster is very resistant to morphine - no sedation or hypnotic effects.
Syrian or golden hamster has an increased tolerance to pentobarbital.

Drug Indication and Drugs Dosage and Route of Administration

Restraint/Pre-Anesthesia

Atropine 0.1 mg/kg IP IM SC
Ketamine, C-III (Ketaset®, Vetalar®) 22-44 mg/kg IM

11.3 - Species Information: Rat


RAT (Rattus norvegicus)

Physiologic Parameters

Body temperature = 35.9-37.5oC
Heart rate = 250-450/min
Respiratory rate = 70-115/min
Tidal volume = 0.6-2.0 ml

Male rats and animals receiving low calorie diets require higher doses of barbiturates.

Avertin has been reported to cause ileus in rats.

The therapeutic dose for carbon dioxide is close to the lethal dose; very short acting. Concurrent administration of 10-50% O2 is recommended.

11.2 - Species Information: Mouse


MOUSE (Mus musculus)

Physiologic Parameters

Body temperature = 36.5-38.0oC
Heart rate = 325-780/min
Respiratory rate = 94-163/min
Tidal volume = 0.09-0.23 ml

The use of chloroform as an anesthetic agent is discouraged. Chloroform can cause renal tubular calcification and/or necrosis, particularly in male mice; DBA/2 strain most susceptible.

Chapter 11 - Anesthesia and Analgesia for Laboratory Animals


Policy on Analgesic Use

  • Analgesics must be provided to all animals following survival surgery unless scientific justification for withholding post-operative analgesics is provided by the investigator and approved by the IACUC, or if a veterinarian examines the animal and determines that analgesic administration is no longer necessary.
