초록

이번 연구는 비글 개에서 medetomidine(D), medetomidine, tiletamine/zolazepam(DZ) 합제, medetomidine, tiletamine/zolazepam, tramadol(DZT) 합제를 이용한 진정/마취 후 심근 기능을 평가하였다. 10 마리의 건강한 성견 비글(체중 $8.6{\pm}1.0$ kg)를 이번 연구에 사용하였다. M-mode 심장초음파를 사용하여 심박수(HR), 구획단축률(%FS), 좌심실 박출기계수(%LVEF), 박출량(SV), 심박출량(CO), 수축기 좌심실 내강 직경 (LVIDs), 이완기 좌심실 내강 직경(LVIDd)을 마취 전, 그리고 마취 후 10분 간격으로 60분 동안 측정하였다. HR, %FS, %LVEF, SV, CO 는 D, DZ 합제, DZT 합제 로 진정된 동안 심각하게 감소하였다. 이번 실험에 사용된 마취 프로토콜은 사용 가능할 정도의 진정/마취가 이뤄졌지만, 심혈관계 압박의 정도가 심했고 지속적이었고, 따라서, 어떠한 상황에서도 생체지수에 대한 모니터링이 동반되어야 한다. 본 마취 프로토콜은 심장질환을 가지고 있어서 심맥관계 억압의 가능성이 높은 환자에서는 주의해서 사용해야 한다.

This study evaluated the myocardial performance on echocardiography after the sedation/anesthesia of medetomidine (D), the combination of medetomidine and tiletamine/zolazepam (DZ), and the combination of medetomidine, tiletamine/zolazepam and tramadol (DZT) in Beagle dogs. Ten healthy adult Beagle dogs (weighing $8.6{\pm}1.0kg$) were enrolled in this study. Heart rate (HR), fractional shortening (%FS), left ventricular ejection fraction (%LVEF), stroke volume (SV), cardiac output (CO), left ventricular internal diameter in systole (LVIDs) and left ventricular internal diameter in diastole (LVIDd) using M-mode echocardiography were measured prior to anesthesia, then every 10 min for 60 min. The HR, %FS, %LVEF, SV and CO were significantly decreased during sedation/anesthesia with D, DZ and DZT combination of anesthesia. Although those anesthetic protocols provided acceptable quality of sedation/anesthesia, levels of cardiovascular suppression were substantial and persistent and thus the continuous monitoring on vital signs should be accompanied in any situation. Close attention is required for dogs with pre-existing heart diseases, when those anesthetic protocols were applied.
