Abstract

OBJECTIVE

To compare sedation following premedication delivered subcutaneous (SC) injection at or adjacent to the Governing Vessel 20 acupuncture location (GV20adj), interscapular SC injection (iscapSC), or lumbar epaxial intramuscular (IM) injection.

ANIMALS

Cats receiving ovariohysterectomy or castration surgery, randomly allocated to GV20adj ( = 18), iscapSC ( = 18), or IM ( = 20) groups.

PROCEDURE

Premedication consisted of dexmedetomidine (10 μg/kg) and methadone (0.2 mg/kg). Sedation, infrared temperature (GV20adj and iscapSC sites), and signs of nausea and vomiting were recorded.

RESULTS

The GV20adj injection resulted in greater sedation than iscapSC injection ( < 0.05) and similar sedation compared to IM injection. Sedation was more consistent with GV20adj than IM injection. Site temperature was higher at the GV20adj site than the iscapSC site ( < 0.0001). Nausea symptoms were similar between groups ( = 0.209), with increased vomiting in the iscapSC group (15/18 cats) compared to GV20adj (8/18, = 0.035) and IM groups (9/20, = 0.021).

CONCLUSION

Sedation GV20adj injection was similar to, but more consistent than, IM injection, and superior to iscapSC injection. Higher GV20adj site temperature suggested greater perfusion, potentially explaining differences in sedation and vomiting.

CLINICAL RELEVANCE

The GV20adj injection route in cats is a viable route for premedication or sedation.

摘要

目的

比较在督脉20穴位（GV20adj）处或其附近进行皮下（SC）注射、肩胛间皮下注射（iscapSC）或腰部轴旁肌内注射（IM）进行术前用药后的镇静效果。

动物

接受卵巢子宫切除术或去势手术的猫，随机分为GV20adj组（n = 18）、iscapSC组（n = 18）或IM组（n = 20）。

方法

术前用药包括右美托咪定（10μg/kg）和美沙酮（0.2mg/kg）。记录镇静效果、红外温度（GV20adj和iscapSC部位）以及恶心和呕吐症状。

结果

GV20adj注射产生的镇静效果比iscapSC注射更强（P < 0.05），与IM注射产生的镇静效果相似。与IM注射相比，GV20adj注射的镇静效果更稳定。GV20adj部位的温度高于iscapSC部位（P < 0.0001）。各组之间恶心症状相似（P = 0.209），但iscapSC组呕吐增加（15/18只猫），与GV20adj组（8/18，P = 0.035）和IM组（9/20，P = 0.021）相比。
