A 14-year-old boy was receiving subcutaneous infusions of treprostinil for pulmonary artery hypertension. Because he had severe infusion site pain in the lower abdomen, we changed his infusion site to the upper buttocks, adding some analgesics. His pain improved gradually. This change may be an effective method for reducing infusion site pain in subcutaneous treprostinil therapy, particularly in children.

以上臀部为皮下部位为肺动脉高压患儿输注曲前列素

一名 14 岁男孩因肺动脉高压而接受皮下注射曲前列环素。由于他的下腹部输液部位疼痛剧烈，我们将他的输液部位改为上臀部，加了一些镇痛药。他的疼痛逐渐好转。这种变化可能是减少皮下曲前列素治疗中输注部位疼痛的有效方法，特别是在儿童中。
