The book "Near-infrared spectroscopy: diagnosis of neonatal hypoxia-ischemia" by Kenneth Tichauer provides a comprehensive analysis of the application of near-infrared spectroscopy for diagnosing hypoxia-ischemia in newborns. It highlights the risks associated with asphyxia during birth and the potential brain damage that can result. A central theme of the book is the importance of early prognosis and treatment to improve outcomes for affected newborns. The technique presented is minimally invasive and allows for precise measurement of brain metabolism and blood circulation, making it a promising diagnostic tool. The book also offers an overview of the current state of clinical care for asphyxiated newborns and validates the diagnostic capabilities of near-infrared spectroscopy.
