Effect of Infusion Warming on Mannitol Infusion Pain in Patients With Acute Ocular Hypertension

Brief Summary

Acute ocular hypertension is a common ophthalmic emergency that often requires rapid reduction of intraocular pressure. Intravenous mannitol is widely used for this purpose, but infusion-related pain and local venous irritation may reduce patient comfort, interfere with infusion speed, and affect treatment experience. This randomized controlled study aims to evaluate whether use of an infusion warming device during intravenous mannitol administration can reduce infusion-related pain, improve patient comfort, decrease local infusion-related complications, and improve infusion efficiency and short-term intraocular pressure outcomes in patients with acute ocular hypertension. Participants with acute ocular hypertension who required intravenous mannitol treatment were randomly assigned to either a warming group or a non-warming group. In the warming group, mannitol was administered using an infusion warming device; in the non-warming group, mannitol was administered according to routine practice without warming. Outcomes included peak pain score during infusion, comfort score, infusion rate, infusion duration, local infusion-related adverse reactions, and intraocular pressure change after treatment.
