Pancreatic enzyme supplementation is an important part of management for a number of gastrointestinal conditions. For patients who are unable to swallow pancreatin capsules or granules, enteral feeding tubes can be used to administer the pancreatic enzyme. This presents challenges given the unique format of the pancreatic enzyme supplements, with common problems including tube blockage and loss of the enzyme's effect.
A novel technique is described for administration of pancreatic enzyme via feeding tubes. For gastrically placed tubes, this involves opening the pancreatin capsules and suspending the enzyme microspheres in thickened acidic fluid (such as the mildly thickened or "nectar-thick" fruit juice used for dysphagia) for delivery into the feeding tube. This technique minimizes tube blockage by preventing the enzyme from clumping in the tube. For jejunally placed tubes, enzyme microspheres can be crushed and activated with sodium bicarbonate before flushing into the tube, or the activated enzyme mixture can be added to enteral feeds.
Pancreatic enzyme supplementation can continue while patients receive enteral feeding. Using the described technique can help to avoid tube blockage and maintain optimal enzyme activity.
胰酶补充是许多胃肠道疾病治疗的重要组成部分。对于无法吞咽胰酶胶囊或颗粒的患者,可以使用肠内喂养管来给予胰酶。但鉴于胰酶补充剂的独特形式,这带来了一些挑战,常见问题包括管腔堵塞和丧失酶的作用。
本文描述了一种通过喂养管给予胰酶的新方法。对于胃内放置的管子,将胰酶胶囊打开,将微球悬浮在浓稠的酸性液体中(如用于吞咽困难的轻度浓稠或“花蜜稠”果汁),然后输送到喂养管中。这种技术通过防止酶在管腔中结块,最大限度地减少了管腔堵塞。对于空肠内放置的管子,可以在将微球压碎并与碳酸氢钠混合激活后冲洗入管内,或者将激活的酶混合物添加到肠内喂养中。
患者接受肠内喂养时可以继续进行胰酶补充。使用描述的技术可以帮助避免管腔堵塞并保持最佳的酶活性。
