Hydrogen inhalation ameliorates oxidative stress in transplantation-induced intestinal graft injury
Buchholz BM et al. · Am J Transplant. 2008;8(10):2015–2024.
What kind of evidence is this?
Preclinical
Controlled syngeneic orthotopic small-intestinal-transplant experiment in rats
Critical care and ischemia-reperfusion
Inhaled H₂
Not reported in this record.
Not reported in this record.
Methods at a glance
Lewis-rat intestinal donors and recipients after 3 hours of cold ischemia
Group and total sample sizes require further extraction from the freely accessible article
Perioperative exposure; principal outcomes 24 hours after transplantation
Donors and recipients inhaled 2% H₂ perioperatively
H₂ diluted in air — not Brown’s gas.
2% H₂ in air.
Not reported — the accessible abstract gives concentration but no H₂ flow in mL/min.
O₂ was present at the ambient-air fraction; no supplemental O₂ or absolute O₂ flow was reported.
Perioperative air without added H₂
Outcomes and reported result
Gastrointestinal transit, muscle contractility, inflammatory mediators, lipid peroxidation, histology, permeability and remote-lung inflammation
The article reports improved graft transit and contractility and lower inflammatory, oxidative, barrier-injury and remote-lung measures with H₂ inhalation.
Gas concentration, model and principal results extracted; group sizes, exact chamber flow, funding and complete methods require further full-text extraction.
A reported association, difference or mechanism is not automatically a clinical benefit. Null findings, outcome type, study design and precision all matter.
Cautions and applicability
Rat transplantation model, perioperative exposure, multiple organ outcomes and incomplete flow/sample extraction. It is not a clinical transplantation trial.
Experimental small-intestinal transplantation in rats.

No single-study GRADE certainty rating is assigned. Certainty is assessed by important outcome across a complete eligible evidence set, not by attaching a final grade to one source.
