The purpose was to review our experiences and determine if applying the sky blue method is reliable in confirming gastric tube (GT) placement in neonates.
The study population consisted of 44 infants (55 placements) who were admitted to the Takeda General Hospital between April 2012 and March 2013 and who required GT exchange. The sky blue method using indigo carmine (IC) was indicated for planned tube exchange only. Diluted IC was injected into the gastric space via the old GT just before the tube exchange. The tube was exchanged using a standard method. Then, we checked whether the diluted IC could be collected through the new GT or not.
The reasons for GT placement were a gestational age of < 35 weeks in 31 (56.4%), poor sucking or swallowing disorders in 17 (30.4%), and respiratory disorders in 7 (12.7%) of the 55 placements. GT placement using the sky blue method was considered successful in 52 placements (94.4%), with the remaining 3 placements (5.6%) considered to be failures due to the inability to obtain IC from the gastric space. No adverse events were observed during the tube exchange period.
Based on the results, the sky blue method can be considered to be reliable method for the confirmation of GT placement. These results also suggest that the number of radiologic evaluations performed to confirm correct replacement of the GT in infants can be reduced in the future.
目的是回顾我们的经验，并确定应用天蓝色法确认新生儿胃管（GT）置入是否可靠。
研究对象为2012年4月至2013年3月期间入住武田综合医院且需要更换GT的44例婴儿（55次置管）。仅在计划更换胃管时采用靛胭脂（IC）天蓝色法。在更换胃管前，通过旧的胃管将稀释后的IC注入胃腔。采用标准方法更换胃管。然后，检查是否能通过新的胃管收集到稀释后的IC。
55次置管中，胃管置入的原因有：胎龄<35周者31例（56.4%），吸吮或吞咽功能差或有障碍者17例（30.4%），呼吸功能障碍者7例（12.7%）。采用天蓝色法进行胃管置入，52次置管（94.4%）被认为成功，其余3次置管（5.6%）因无法从胃腔获取IC而被认为失败。在更换胃管期间未观察到不良事件。
基于这些结果，天蓝色法可被认为是确认胃管置入的可靠方法。这些结果还表明，未来可减少用于确认婴儿胃管正确更换的放射学评估次数。
