Effect of Electroacupuncture Analgesia on Changes of Vital Signs and Blood Chemical Values in Cats

다국어 초록 (Multilingual Abstract)

The present study was performed to investigate the anesthetic or analgesic effect of tiletamine-zolazepam
(TZ) and electroacupuncture analgesia (EAA) in cats. Twelve healthy cats were randomly assigned to receive either
TZ or EA. TZ group cats with weight of 3.65 ± 0.48 kg received 10.0 mg/kg of TZ intramuscularly. EA group cats
with weight of 3.62 ± 0.52 kg received 5 V, 30 Hz and 60minutes of EA. The acupoints used were Tian-ping (GV-5, +),
Bai-hui (GV-20, −). Therefore, after and before experiment, some serum chemistry profiles (alkaline phospatase, aspartate
aminotransferase, alanine aminotransferase, glucose and total protein) and change of vital signs (rectal temperature,
heart rate, respiratory rate) were examined. All cats were examined pre, and 5, 25, 65 and 105 minutes after
administration of TZ or operation of EA. The cats in EA group showed a smaller change in rectal temperature, heart
rate and respiratory rate than in the TZ group (p < 0.05). In both groups, total protein concentration was constant
throughout the period of anesthesia, and the serum glucose increased gradually throughout the period of anesthesia.
However, the cats in EA group showed a smaller change in alkaline phospatase, aspartate aminotransferase and alanine
aminotransferase within the limit of safety than in the TZ group (p < 0.05). While coming to induction, the TZ group
took a mean 2.4 ± 0.7 minutes to achieve sternal recumbency, compared with 10.5 ± 2.1 minutes by the EA group,
and 3.2 ± 0.6 minutes to achieve lateral recumbency, compared with 18.8 ± 1.9 minutes by the EA group (p < 0.05).
When recovering from anesthesia, the TZ group took 164.3 ± 17.9 minutes to achieve sternal position time, compared
with 67.7 ± 4.6 minutes by the EA group, and 202.0 ± 15.7 minutes to stand, compared with 73.0 ± 6.1 minutes for
the EA group (p < 0.05). In this study, the cats anesthetized with EA showed a more rapid recovery rather than the
cats under TZ anesthesia. Also, there do not appear to be any negative physiologic effects associated with acupunctureinduced
surgical analgesia. So, it was considered that EAA may be used effectively in shock, debilitated cats, as
compared to TZ.
