Objective To evaluate the possibility of monitoring regional tissue oxygen saturation by near-infrared spectroscopy (NIRS) for early predicting adverse events in patients with pulmonary atresia.Methods Twenty-six patients aged under 3 months who were diagnosed with pulmonary atresia and admitted to cardiovascular intensive care unit in our hospital between January 2016 and May 2017, accepted regional tissue oxygenation (cerebral and splanchnic) by near-infrared spectroscopy. There were 19 males and 7 females at age of 2–89 days. A total of 625 times of heart rate, blood pressure, pulse saturation, regional tissue oxygenation, and 98 serum lactate were retrospectively analyzed. The relationship of the tissue oxygen saturation and clinical adverse events was explored.Results The adverse event by routine monitoring was 69 (11.04%) person-time: isolated hypoxia in 27, hypoxia combined increased lactate in 16, hypotension in 6, hypotension combined increased lactate in 17, isolated increased lactate in 3. A reduction of 12.80% in cranial oxygen predicted the high probability of adverse events, with a sensitivity of 85.30% and a specificity of 87.00%. A reduction of 20.60% in splanchnic oxygen predicted the high probability of adverse event, with a sensitivity of 73.50% and a specificity of 91.2%. On average, the splanchnic oxygenation had fell 3 minutes before a reduction of blood pressure, or 45 minutes before an increase in lactate.Conclusion For preoperative patients with pulmonary atresia, a fall of 12.80% in cranial oxygen saturations, or of 20.60% in splanchnic oxygen saturation, should attract clinician’s awareness.
