Dental procedures are a common reason for general anesthesia, and there is widespread concern among veterinarians that heart disease increases the occurrence of anesthetic complications. Anxiety about anesthetizing dogs with heart disease is a common cause of referral to specialty centers. To begin to address the potential effect of heart disease on anesthetic complications in dogs undergoing anesthesia for routine dental procedures, we compared anesthetic complications in 100 dogs with heart disease severe enough to trigger referral to a specialty center (cases) to those found in 100 dogs without cardiac disease (controls) that underwent similar procedures at the same teaching hospital. Medical records were reviewed to evaluate the occurrence of anesthetic complications. No dogs died in either group, and no significant differences were found between the groups in any of the anesthetic complications evaluated, although dogs in the heart disease group were significantly older with higher American Society of Anesthesiologists scores. Midazolam and etomidate were used more frequently, and alpha-2 agonists used less frequently, in the heart disease group compared to controls. This study suggests dogs with heart disease, when anesthetized by trained personnel and carefully monitored during routine dental procedures, are not at significantly increased risk for anesthetic complications.
牙科手术是全身麻醉的常见原因，兽医们普遍担心心脏病会增加麻醉并发症的发生率。对患有心脏病的犬只进行麻醉的担忧是转诊至专科中心的常见原因。为了开始探讨心脏病对接受常规牙科手术麻醉的犬只麻醉并发症的潜在影响，我们将100只患有严重心脏病且已转诊至专科中心的犬只（病例组）与100只在同一教学医院接受类似手术的无心脏病犬只（对照组）的麻醉并发症进行了比较。查阅病历以评估麻醉并发症的发生情况。两组均无犬只死亡，在评估的任何麻醉并发症方面，两组之间均未发现显著差异，尽管心脏病组的犬只年龄显著更大，美国麻醉医师协会评分更高。与对照组相比，心脏病组咪达唑仑和依托咪酯的使用频率更高，α-2激动剂的使用频率更低。这项研究表明，患有心脏病的犬只在由训练有素的人员进行麻醉并在常规牙科手术期间进行仔细监测时，发生麻醉并发症的风险不会显著增加。
