Pain in babies
Pain in babies, and whether babies feel pain, has been the subject of debate within the medical profession for centuries. Prior to the late nineteenth century it was generally considered that babies hurt more easily than adults.〔"The immaturity of the nervous system affecting mostly inhibitors filters; a whole body of evidence now suggests that the pain would be increased, potentiated by reducing the segmental spinal cord controls." (Dr Daniel Annequin, 1999 ) in french : L'immaturité du système nerveux touche plus particulièrement les filtres inhibiteurs; tout un faisceau d'arguments suggère maintenant que la douleur serait augmentée, potentialisée par la diminution de ces contrôles segmentaires médullaires.〕 It was only in the last quarter of the 20th century that scientific techniques finally established babies definitely do experience pain – probably more than adults – and has developed reliable means of assessing and of treating it.
==Effects==
There are a number of metabolic and homeostatic changes which result from untreated pain, including an increased requirement for oxygen, accompanied by a reduction in the efficiency of gas exchange in the lungs. This combination can lead to inadequate oxygen supply, resulting in potential hypoxemia. In addition, a rise in stomach acidity accompanies the stress reaction precipitated by pain, and there is a risk of aspirating this into the lungs, further endangering lung integrity and tissue oxygenation. In cases of acute, persistent pain, the metabolism becomes predominantly catabolic, causing reduced efficiency of the immune system and a breakdown of proteins caused by the action of the stress hormones. In combination, healing of damaged or infected tissue may be impaired, and morbidity and mortality increased.
The neuropsychological effect on the bonding between mother and child, on later contact with health professionals, and on personal and social psychological well-being is difficult to quantify. Research suggests that babies exposed to pain in the neonatal period have more difficulty in these areas. Professionals working in the field of neonatal pain have speculated that adolescent aggression and self-destructive behaviour, including suicide, may, in some cases, be attributed to the long-term effects of untreated neonatal pain.
