초록

본 연구는 비글견에서 medetomidine-midazolam-ketamine 병용 마취 시 마취효과와 심혈관계 및 호흡기계에 미치는 영향을 평가하였다. Medetomidine 0.015 mg/kg (MMK-L군) 또는 medetomidine 0.02 mg/kg (MMK-H군)을 근육 주사한 후에 midazolam (0.3 mg/kg) 및 ketamine (5 mg/kg)을 근육 주사하였다. 마취유도 및 회복시간, 진정 및 진통점수, 심박수, 혈압, 직장 온도 및 호흡수 측정 및 동맥혈액가스분석을 실시하였다. 평균 마취 시간은 MMK-L군 ($52.4{\pm}11.08$분)과 MMK-H군($78.2{\pm}20.72$분)이 유의성 있게 달랐다. 두 군 모두에서 MMK 투여로 인해 개에서 만족스런 진정 및 진통을 얻을 수 있었다. 두 군 모두에서 심박수는 유의적인 감소를 보였으며 MMK-H군은 투여 후 5분부터 MMK-L군은 투여 후 20분부터 유의적인 심박수의 저하가 확인되었다. MMK 투여 후 두 군 모두에서 혈압은 증가하였으나 두 군사이의 유의적인 차이는 확인되지 않았다. 실험 결과 비글견에서 medetomidine-midazolam-ketamine 병용마취는 양호한 마취효과를 나타냈으며, 개의 MMK 병용마취에서 부작용을 최소화 하면서 만족할 만한 마취효과를 얻을 수 있는 medetomidine의 용량은 0.015 mg/kg 인 것으로 생각된다.

This study was performed to examine the anesthetic and cardiopulmonary effects of medetomidine, midazolam and ketamine (MMK) combination in ten beagle dogs. Dogs were randomly allocated to two groups. Treatment group MMK-L received 0.015 mg/kg medetomidine followed by 0.3 mg/kg midazolam and 5 mg/kg ketamine by intramuscular injection. Treatment group MMK-H received 0.02 mg/kg medetomidine followed by 0.3 mg/kg midazolam and 5 mg/kg ketamine by intramuscular injection. Induction, anesthesia, sternal recumbency, standing, walking time, heart rate, arterial blood pressure, rectal temperature, respiratory rate and arterial blood gases were measured. Mean anesthesia time was significantly different between MMK-L group ($52.4{\pm}11.08$ minutes) and MMK-H group ($78.2{\pm}20.72$ minutes). Sedative scores and noxious stimuli were raised to the maximum value at 5 minutes after administration of the test dose and maintained until 40 minutes in both groups. In both groups, the heart rate significantly decreased after MMK administration. The blood pressures (MAP, SAP and DAP) increased after MMK administration but there were no significant differences in blood pressures between two groups. In conclusion, intramuscular administration of medetomidine followed by intramuscular injection of midazolam and ketamine in beagle dogs, leads immediate and sufficient anesthesia and proper doses of medetomidine for minimal adverse effects in intramuscular MMK combination will be 0.015 mg/kg in dogs.
