Revision as of 13:33, 11 January 2024
Paul Emil Flechsig (29 June 1847 in Zwickau, Kingdom of Saxony – 22 July 1929 in Leipzig, Germany) was an eminent nineteenth-century German neuroanatomist, psychiatrist, and neuropathologist.
Professor Flechsig had an interest in myelinogenesis — the development of the myelin sheaths for nerves.[1] The myelin acts as an insulator to allow the electrical impulses to travel through the nerves.[1]
Flechsig (1872) observed that the myelin sheath is not yet formed in newborn babies,[2] which he reported in 1876.[3] Unfortunately, he came to the unfounded conclusion that the newborn cannot feel pain.[4] So great was his reputation and influence that his views were accepted without question, even though empirical studies had not been carried out. Surgical operations were carried out on infants without pain medication.
Publications
Flechsig PE (1927): Meine Myelogenetische Hirnlehre: Mit Biographischer Einleitung. [My myelogenetic brain theory: With a biographical introduction] (German). ISBN 978-3-662-32788-3. Retrieved 8 January 2024.
Professor Flechsig published numerous books, articles, and other publications in German on a wide variety of subjects. In accordance with Intactiwiki policy they will not be listed here.
Flechsig's views are disproved
It was not until a century later that medical science started to question his views. Talbert et al. (1976) measured the rise in cortisol and cortisone in circumcised infants and found an increase in "stress".[5] Gunnar et al. (1981) also examined serum cortisol and behavior after neonatal circumcision. They reported "striking increases in serum cortisol concentrations" after unanesthetized non-therapeutic circumcision.[6]
Anand & Hickey (1987) published a magisterial article in the New England Journal of Medicine that conclusively settled the issue. The authors stated:
Numerous lines of evidence suggest that even in the human fetus, pain pathways as well as cortical and subcortical centers necessary for pain perception are well developed late in gestation, and the neurochemical systems now known to be associated with pain transmission and modulation are intact and functional. Physiologic responses to painful stimuli have been well documented in neonates of various gestational ages and are reflected in hormonal, metabolic, and cardiorespiratory changes similar to but greater than those observed in adult subjects. Other responses in newborn infants are suggestive of integrated emotional and behavioral responses to pain and are retained in memory long enough to modify subsequent behavior patterns.[7]
Conclusion
Flechsig's error condemned millions of infant girls and boys to acute pain, trauma, and shock for more than a century and that practice is still ongoing today. Open heart surgery on infants was done without anesthesia until 1987.[8] The AAP belatedly acknowledged the need for anesthesia in 1987.[9] Boys may have suffered more than girls because of the practice of non-therapeutic neonatal circumcision, including the after effects of behavior changes[10] and PTSD.
