Anaesthesia & Analgesia: General Anaesthesia: Termination of Anaesthesia (excretion of anaesthetic) / Aftercare / treatment of pain
Terms in this set (12)
Especially in small animals it is recommended that the waking phase be kept
as short as possible because of the risk of cooling
If anaesthetics capable of antagonism (opioid, alpha2-agonist or benzodiazepine) are used, the effect
can be rapidly abolished by competitive antagonists
is an antagonist for medetomidine/xylazine anaesthesia
The patient must be regularly monitored until
it is again able to control and regulate its reflexes and bodily functions itself.
The following points should be borne in mind in the waking phase:
prone or lateral positioning of animal to make it easier for them to breath, quiet surroundings, choose suitable material to lie on to avoid injuries or inhalation of substrate, external heat supply, individual housing of animals until awake, food and water only after fully awake, administration of O2 or substitution of physiological liquids such as NaCl, administration of analgesics
treatment of pain after a minor procedure
single dose of an opioid or non-opioid
treatment of pain after a moderately complicated procedure
single dose of an opioid, followed by a non-opioid for 24-48 hours
treatment of pain after a major procedure
an opioid and non-opioid for at least 3 days, followed by a non-opioid for at least 2-3 days.
The optimum interval for administering analgesics depends on
the substance, its half-life and the route of administration (oral, local = patch, epidural, intravenous, intramuscular, subcutaneous) and, like the dose, varies from one animal species to another.
Close postoperative monitoring of the animals using score sheets with species-specific criteria helps
to ensure good analgesia management and to avoid gaps in therapy.
Efforts to use as little analgesic as possible is the wrong way to go. It may even be advisable
to administer a test dose if the pain diagnosis is unclear in order to evaluate whether this changes the wellbeing of the animal for the better.
