[Evolution of the carboxyhemoglobinemia and methemoglobinemia during endoscopic resection: An observational study].

CONCLUSION: MetHb did not increase during endoscopic surgery. In contrast, COHb increases, and can, in some patients, exceed 2-4 %. This could be responsible for a decreased angina threshold in patients with ischemic heart disease. LEVEL OF EVIDENCE: 4. PMID: 28117232 [PubMed - as supplied by publisher]
