Abstract

There are many intramuscularly injectable drugs commonly used for anesthesia in dogs and combination of drugs were used for decrease the side effects. The objective of this study was to evaluate the anesthetic and cardiopulmonary effects of butorphanol-tiletamine-zolazepam-medetomidine and tramadol-tiletamine-zolazepam-medetomidine in dogs. Ten healthy beagle dogs (intact male; mean body weight : $9.5{\pm}1.60$ kg) were used in the study. Experimental animals were divided into two groups (n=5, each) and received 0.2 mg/kg of butorphanol (BZM) and 2 mg/kg of tramadol (TZM) according to the group after injection of $Zoletil^{(R)}$ (5 mg/kg) and medetomidine (10 ug/kg). All drugs were administered intramuscularly. Anesthesia and recovery, sedation and analgesia score, cardiovascular and respiratory parameters were measured. Induction and recovery time were not significantly different between the groups. Anesthesia time was $117.4{\pm}25.64$ minute and $81.2{\pm}12.50$ minute in BZM and TZM groups, respectively. Sedation and analgesia were satisfied in both groups. In both groups, common side effects related to the medetomidine, significant bradycardia and hypertension were not observed. There were no significant changes in respiratory data. In conclusion, tiletamine-zolazepam-medetomidine in combination with either butorphanol or tramadol can be suitable anesthetic protocol for minor procedures in dogs. They produced adequate anesthesia characterized by rapid induction, adequate analgesia and muscle relaxation without remarkable side effects.

개의 마취를 위해 많은 주사용 마취제를 사용하고 있으며, 그 부작용을 줄이기 위하여 다양한 약물을 병용하여 사용한다. 본 실험은 개에서 tiletamine-zolazepam-medetomidine과 함께 butorphanol 또는 tramadol을 병용투여 하여 마취효과 및 심폐기능에 미치는 효과를 비교하였다. 임상적으로 건강한 중성화 하지 않은 10 마리의 수컷 비글견 (체중: 평균 $9.5{\pm}1.60$ kg)을 사용하였다. 실험군은 BZM군과 TZM군으로 나누었으며, BZM군은 0.2 mg/kg의 butorphanol과 tiletamine (2.5 mg/kg)-zolazepam (2.5 mg/kg)-medetomidine (10 ${\mu}g/kg$)의 혼합용액을 0.1 ml/kg의 용량으로 투여하였다. TZM군에서는 2 mg/kg의 tramadol과 동량의 혼합용액을 투여하였다. 모든 주사는 근육 내로 투여하였다. 마취유도 및 회복시간, 진정 및 진통점수, 심박수, 혈압, 직장온도 및 호흡수를 측정하였으며 동맥혈액가스분석을 실시하였다. 마취유도시간과 회복시간에는 BZM과 TZM군간 유의성은 없었으며, 두 군간 마취시간은 BZM군 ($117.4{\pm}25.64$ minutes)이 TZM군 ($81.2{\pm}12.50$ minutes)보다 유의성 있게 길었다. 진정 및 진통은 BZM군과 TZM군 두 군 모두에서 만족스러운 결과를 얻었다. 심박수는 투여 후 20분부터 두 군 모두에서 유의성 있게 감소하였으며 군간 유의적인 차이는 없었다. 두 군에서 혈압과 직장온도는 유의적인 차이를 보이지 않았다. 호흡수는 TZM 군에서 투여 후 30분에 BZM군보다 유의적인 증가를 나타내었다. 동맥산소분압($PaO_2$) 및 동맥산소포화도($SaO_2$)는 군 간 유의적인 차이를 보이지 않았다. 본 실험 결과를 바탕으로 개에서 butorphanol-tiletamine-zolazepam-medetomidine 및 tramadol-tiletaminezolazepam-medetomidine 병용마취는 만족할만한 마취효과를 얻을 수 있었으며 심폐기능에 큰 영향을 미치지 않았으므로, 단 시간의 마취가 필요한 진단 또는 가벼운 수술에 효과적으로 적용될 수 있을 것으로 생각한다.
