Researchers discover possible method to relieve pain in neonates measure
Scientists think they have found a method to have found to the pain that babies experience to be able to measure. By brain activity in infants to measure would be can be assessed, or the child is experiencing pain.
The results of the research, in Science Translational Medicine, are published, the coming time will be used to measure the effectiveness of painkillers for babies to investigate.
British researchers placed at eighteen babies electrodes on the head and chest while keeping the heel prick test had. The electrodes are laid on an Electro-Encefalografie (EEG) the electrical activity of the children when they are pricked. On the graph of the EEC was seen that the stimuli in the brain changed as soon as the children pain experienced.
Then it was up to 72 babies tested whether the means of measurement is valid. This was a heel prick test-EEG compared with EEG which was created while children of a non-painful stimulus were administered. So they were exposed to bright light or loud sound. From this second test showed that the pattern in the chart is not the same as in the pijnprikkel of the heel prick test.
Also found the researchers that the graph changed when the child during a painful stimulus, an analgesic was given. When the heel of the child was smeared with numbing cream, reduced brain activity, while in the brain activity, nothing changed if the cream was not lubricated. In this way knew the scientists a pattern in the brain activity to figure out that occurs when pain.
Research leader Rebecca Slater of the University of Oxford recognises that the measuring instrument is never absolute certainty can provide. “Even in people who can talk, it remains difficult to determine whether they experience pain. Pain is subjective. The only one who knows how much pain you have, is yourself.”
Dick Tibboel, professor of research intensive care in childhood in the Erasmus MC, calls the research in The newspaper “an important step.” According to Tibboel is the first time that an objective measure is developed for pijnregistratie in children.
Until now doctors could only figure out how much pain a child experiences due to the behavior of the newborns to observe. “There are so-called pain scales, where physical features, scores are awarded. There are more than forty pain scales to measure pain,” says Tibboel. “That shows that we are still not much aware of.
However, to place the professor remarks on research. “That the EEC is changing as a baby’s a pijnprikkel, proves yet one thing: the pijnbanen are well laid out,” he says. “The heel prick test activates pain receptors through the nerves electrical impulses to the ruggenmerk send. There, the impulses are converted into signals sent to the brain.”
Tibboel wonders whether the changes in the EEG pattern also prove that the child actually pain experience and a conscious experience of pain. “Pain is hugely complex. There are parts of the brain involved. It makes a big difference which area you measure.”
