We describe a case in which a patient receiving parenteral nutrition (PN) developed hypophosphatemia. Due to lack of availability of parenteral phosphate supplements, we chose to restore phosphate using diluted hypertonic sodium phosphate enemas. Due to the recent shortages of parenteral minerals and vitamins, such an alternate means of repletion is of increasing importance. Diluted hypertonic sodium phosphate enemas are inexpensive, easy to administer, and effective since phosphate is readily absorbed across the rectal mucosa. We hope that through this type of repletion, life-threatening hypophosphatemia among patients receiving PN can be avoided.
我们描述了一例接受肠外营养（PN）的患者发生低磷血症的情况。由于无法获得肠外磷酸盐补充剂，我们选择使用稀释的高渗磷酸钠灌肠来恢复磷酸盐。由于最近肠外矿物质和维生素短缺，这种替代补充方法变得越来越重要。稀释的高渗磷酸钠灌肠价格低廉，易于管理，且效果确切，因为磷很容易通过直肠黏膜吸收。我们希望通过这种补充方式，避免接受 PN 的患者发生危及生命的低磷血症。
