　未熟児無呼吸発作に対して，患児に手指を用いないで迅速な回復刺激が可能となる小型軽量バイブレーターを用いた無呼吸回復刺激装置を試作した。対象は新生児集中治療室に入室した低出生体重児17例（在胎週数27.8±1.9週，出生体重1,031±251g）で，認められた無呼吸発作の74.0%は本装置を用いて10秒以内に無呼吸状態から回復させることができた。なお，在胎24週の1例において振動部接触部位である足底に水疱形成を認めたため，装置の使用を一時中止した。本装置は消毒不十分な手指による回復刺激の頻度を減らせるという点で，未熟児無呼吸発作管理の一手段となり得る可能性が示唆された。

　We developed and examined the usefulness of a new breath-stimulating device that does not require direct manipulation by health workers during apnea of prematurity. The device, which is small and is wired with a vibrating unit, was fixed to the sole of the infants and was used to stimulate breathing during apnea. We utilized the device in 17 infants with a mean birth weight of 1,031 g（range：781-1,534 g）and a mean gestational age of 27.8 weeks（range：24-30 weeks）. The incidence of rapid restart of breathing was 74.0% in these infants. Only one patient who was born at 24 weeks gestation was discontinued from using the device because of sole blistering. Thus, we were able to reduce the necessity for stimulating infants with health workers’ fingers. In conclusion, our device may be helpful in managing apena of prematurity in the neonatal intensive care unit.
