Papel da eletroanalgesia na função respiratória de pacientes submetidos à operação de revascularização do miocárdio

Abstract

Objective: To assess the electroanalgesia as an effective method in the reduction of pain and consequent improvement in lung function in patients undergoing coronary artery bypass graft surgery. Methods: During the period of one year were studied 30 patients undergoing surgery for treatment of the ischemic coronary disease. After randomization, 15 patients were allocated in the study group (that received electroanalgesia) and 15 patients from the control group (placebo). From the 1st until the 5th postoperative day were performed two applications of eletroanalgesia or the placebo current, according to the group where the patient was allocated. Results: There was a reduction in the levels of pain in the study group compared to the control group, evidenced by the value P<0,05; however, there is no evidence of statistical difference of the spirometric variables between them. Conclusion: The group that did eletroanalgesia presented reduction in the intensity of postoperative pain, which however did not mean improvement in respiratory function of these patients.
