| Summary: | The association of tiletamine with
zolazepam (T/Z) is commonly used in
dissociative anesthesia in household pets.
This combination induces short-duration
somatic analgesia, loss of voluntary
movements and myorelaxation caused by
the benzodiazepin, with stimulation of the
ardiovascular system and maintenance of
protective reflexes. Due to the large use of
this association in elective neutering of
felines and its anesthetic properties, we
chose to monitorize and identify
electrocardiographic (ECG) and clinical
changes during the anesthetic procedure,
with and without oxygen supplementation.
For this study, 20 female felines were
recruited. All animals were young adults,
healthy, no specific breed. The subjects
underwent clinical, laboratorial and
electrocardiographic evaluations prior to
anesthesia. Tramadol hydrochloride was
given as Preanesthetic medication
followed by anesthesia with T/Z. The
felines were randomly assigned to either
Group 1 (n=10), in which subjects received
oxygen supplementation through mask
during the anesthetic procedure, or Group
2 (n=10), in which subjects were not
supplemented with oxygen. Heart and
respiratory rates, systolic blood pressure,
rectal temperature and pulse oxymetry
were monitored in all subjects from both
groups. We also obtained recordings of
the ECG tracing and derivations for each
animal which were posteriorly evaluated
and interpreted. The results showed
significant differences between the groups
in respiratory rate (G1 = 26,8 +/- 2,1 and
G2= 38,5+/- 3,2) and pulse oxymetry (G1=
97,3 +/- 2,4% and G2 = 91,2 +/- 1,1%).
We also observed on the ECG recordings
development of periods of intermittent right
branch blockage and S-T elevation in both
groups. We therefore concluded that the
ECG recordings were identical in both
groups despite oxygenotherapy; however,
we observed an improvement in the
clinical parameters in animals who
received oxygen supplementation via
mask. |
