Abstract

The effectiveness of hyperbaric oxygen treatment for acute cardiac diseases is unknown. Similarly, the effectiveness of hyperbaric oxygen treatment for carbon monoxide intoxication is also unknown, particularly for cases in which carboxyhemoglobin (COHb) levels return to normal. Our case study revolved around a healthy twenty-year-old male patient, who suffered from carbon monoxide intoxication. The patient presented to the Emergency Department unconscious. Blood workup revealed significant carbon monoxide intoxication and cardiac injury (COHb = 41%, troponin T = 0.38 ng/dl, ST depression). He was intubated and transferred to a specialist Centre for hyperbaric oxygenation treatment, whilst mechanically ventilated. COHb on arrival (5 hours later) was 4.3%. First echocardiography revealed estimated ejection fraction of 30%, moderate-severe left ventricular dysfunction and global hypokinesis. Patient received 3 rounds of HBOT; each round was 2.4 ATA, 100% O2 and 120 minutes long within the following 24 hours. Afterwards, the patient was successfully extubated. Three days later, a second echocardiography showed remarkable improvement with normal left ventricular size and function. The patient discharged the following day without co...Continue Reading
