RESUMO

On the strengh of the large number of cesareans in Brazil and concerning the humanizing project of the pregnancy-puerperal cycle, it can be observed the importance of researching and prescribing non-pharmacological resources that can help by the recovery of puerperal women from the cesarean section. The pain and the discomfort by reason of the surgery and of those necessary movements for the self-help and to take care of the baby. The Transcutanous Electrical Nerve Stimulation (TENS) is a therapeutic technique commonly used for easing the pain, including the post-operating acute pain. The objective of this research is to analyze the effectiveness of the TENS in the pain relief after cesarean. Hence a simple-blind and a random clinical-controlled study was done. Twenty puerperal women composed the experimental group in which TENS technique was applied and 20 others puerperal women composed the control group in which the pain was only evaluated. The puerperal was evaluated the pain the Numeric Rating Scale (NRS) and the McGill Pain Questionnaire were chosen a first assessment was followed by a 45 minutes session of TENS technique with the experimental group, while the control group was only followed at the same time. After this period happened a second assessment and, an hour later, a third assessment. The puerperal presented limitations in sitting down, stand up and walking movements. The pain was characterized chiefly as rhythmic and located. The words more commonly used to describe pain were "painful", "that holds", "colic" and "that pulls". The highest scores of pain were related to the movements of sitting down, stand up and walking. By this Mann-Whitney non-parametric test, it was possible to observe that the experimental group presented a pain reduction more statistically significant than that of the control group in the second and third NRS (p<0,001) and McGill (p<0,001) assessment. The conclusion is that TENS is an efficient technique to promote pain reduction and resulting relief remains at least an hour after its use. More researches should be developed in order to make possible the use of TENS technique in the clinical practice and as a non-pharmacological humanizing resource in the puerperal condition of cesarean section.
