“…During this period, the environment for mothers and children must be as comfortable as possible.. 11 As stated by Correa and Neves, the prevention, assessment and treatment of neonatal pain are top priorities. It is important to find a solution that allows everyone to work, do a good job, produce better working solutions and define what is needed.. 12 In the studies by Alencar and Ramos, the authors aimed to characterize the assessment of pain in NBs who were hospitalized in the NICU, proposing to demonstrate the importance of properly assessing pain and treating it efficiently..Therefore, the authors determined that scientific evidence demonstrated that in addition to some discomfort caused by a large amount of sensory stimulation in the intensive care unit environment, the NB admitted to the intensive care unit received a procedure that would cause pain, so the use of the pain assessment scale is crucial, so that the newborn can be hospitalized in a more harmonious and humane way. Therefore, it is necessary to adequately prepare the professionals who work in these sectors, and to be attentive to all signs that may indicate that the patient is in a certain state of pain, so that the mechanism mentioned in this study can be used for pain relief, and thus, provide for those who already suffer, newborns bring greater comfort.…”
