Abstract | Diltiazem(DL)bolus投与による心循環系の反応を, 犬を用いIsoflurane(Iso)麻酔下とウレタン・クロラロース麻酔下(対照群)で比較し, 相互作用を検討した. 心循環系へのDLの作用態度は, LV dp/dtと心拍数以外, Iso群と対照群でその程度に差がなく, Isoの存在により影響をうけないと考えられ, さらにDLとIsoの心循環系に対する抑制作用は相加的であると云える. LV dp/dtは高濃度DLによりIso下でより抑制され, 心拍数は抑制程度は対照群と同じであるが, 抑制持続時間がIso下でより長くなった. これらのDLの反応態度は, Halothane下におけるものとほぼ同じであった. |

Abstract | Effects of bolus injection of diltiazem(DL) upon cardiovascular functions were compared between under 1−MAC of isoflurane (Iso group) and urethane−chloralose anesthesia (C group). Blood pressure, systemic vascular resistance, left ventricular pressure transiently (5 min) decreased, cardiac output (CO) and left atrial pressure transiently increased, and left ventricular (LV) dp/dt, pulmonary arterial pressure and resistance (PVR) were not altered in C group. The percent changes in these indices of C group did not differ to those of Iso group, except in CO, LV dp/dt and PVR. The increase in CO was smaller, and LV dp/dt and PVR depressed only with the higher dose of DL in Iso group. DL decreased heart rate (HR) in the same degree (in %) in both group, but the duration of this decrease was longer in Iso group. Thus, Iso does not modified cardiovascular responses to DL, and both drugs interact additively to each other, except on HR and LV dp/dt. |
