Effectiveness of Hydrogen Water Intervention on Acute Oral Inflammation, Oral Microbiota, and Pain Following Free Flap Reconstruction in Patients With Oral Cancer

This randomized, double-blind, parallel-group controlled trial evaluates the effectiveness of hydrogen water oral care on acute oral inflammation, oral microbiota, and pain in patients with oral cancer who have undergone free flap reconstruction. After postoperative transfer from the intensive care unit to the plastic surgery ward, eligible patients who provide written informed consent are randomly assigned in a 1:1 ratio to receive oral care with either hydrogen water or boiled drinking water for 7 days. Saliva samples and pain assessments are collected at baseline (T0), Day 3 (T1), and Day 7 (T2) of the intervention.
