hypovolaemia must be corrected with an appropriate fluid management plan
to restore intravascular volume.
Arterial blood gas: PaO2 should remain above 150 mmHg when using 100%
oxygen as the carrier gas during volatile inhalation agent anaesthesia.
Venous blood gas: The central venous saturation of haemoglobin should be
more than 70%. This indicates adequate blood content of oxygen to meet the
metabolic demand of the patient. This parameter is gaining a tremendous
amount of interest from human and veterinary clinicians working in the
critical care industry (Tranquilli et al. 2007).
Conclusion
Effective monitoring of responses to fluid and pharmacological interventions to
maintain tissue perfusion will allow for effective manipulations of the initial plan.
Some horses require tweaking of the initial plan. Remember to make adjustments
and allow time to gauge the patient’s response. Usually most pharmacological
interventions will take 5 to 15 minutes before you can notice an onset of action.
Remember to always assess anaesthetic depth; excessively deep anaesthesia is
arguably the major cause of hypotension and hypoventilation.
