Аннотация
BACKGROUND: Polyethylene glycol (PEG) is widely used as an additive because of its hydrophilic and chemically inert properties. However, there are been increasing reports of PEG allergies, including anaphylaxis, although they are still rare. This case report aims to raise awareness, that the commonly used bowel cleansing agent containing PEG can cause serious allergic reactions.
CASE SUMMARY: Prior to surgery for sigmoid colon cancer, a 63-year-old man was prescribed a bowel cleansing agent containing PEG. Within 30 min of ingestion, he developed symptoms of anaphylactic shock and did not respond to initial intramuscular epinephrine injection. Under diagnosis of anaphylaxis to PEG, he was stabilized with fluid hydration and continuous norepinephrine infusion.
CONCLUSION: While allergic reactions to PEG are rare, they can be life-threatening. Therefore, it is crucial for clinicians to be aware of this possibility and to diagnose and resuscitate patients immediately.
