背景:改正臓器移植法施行後,全国から小児重症心不全患者の相談が増加するのに伴い,ハイリスク患者の病院間搬送も重要な課題となっている.

方法:2010年7月~2018年12月に重症心不全のため病院間搬送となった42症例を対象とした.患者背景,搬送形態,搬送後補助人工心臓(VAD)装着状況,予後を調査し,病院間搬送に伴う課題を検討した.

結果:原疾患は,拡張型心筋症25例,拘束型心筋症12例,急性心筋炎5例であり,搬送形態は,陸路26例,空路16例であった.人工呼吸管理22例(52.3%),補助循環装着14例(33.3%)と集中治療継続下の搬送が多く,搬送直後に治療強化を要する例が8例あり,より低年齢の症例で必要となる傾向にあった.最終的に8割以上がVAD装着となり,10例が心臓移植に到達,死亡例は11例であった.

結語:小児重症心不全患者の病院間搬送には,早期からの情報共有と状況に応じた搬送計画が重要であり,人員の確保と経験を要する特殊な領域である.同時に中枢ルート確保時の留意や家族ケアにも配慮が必要であり,よりよい病院間搬送の体制づくりが望まれる.

Background: The number of medical consultations for severe heart failure in pediatric patients has been increasing in all regions in Japan. As a result, high-risk interhospital transport is becoming a more challenging task.

Methods: Forty-two pediatric patients with severe heart failure who were transferred to our hospital between July 2010 and December 2018 were reviewed. We investigated patient characteristics, type of transport, and outcomes after transportation, including implantation of a ventricular assist device. We also discuss practical issues of interhospital transportation in Japan.

Results: The underlying cardiac diseases were dilated cardiomyopathy in 25 patients, restrictive cardiomyopathy in 12 patients, and acute myocarditis in 5 patients. Twenty-six patients were transferred by land and 16 patients by air. The continuation of intensive care was mandatory especially in 22 cases (52.3%) with ventilator and 14 (33.3%) with PCPS. More than 80% of cases required VAD implantation after interhospital transport. In addition, 8 cases who needed treatment intensification after transportation tend to be younger. Ten patients underwent heart transplantation, whereas 11 cases were deceased. It is also important to consider appropriate blood access and to provide sufficient information to family members.

Conclusion: Early interhospital collaboration and transport planning based on a patient’s condition are essential for the treatment of severe heart failure in pediatric patients. Interhospital transportation should be supported by a medical team with special experience. To improve the prognosis of severe heart failure in children, we need to consider further improvement in the management of interhospital medical transport.
