RESUMO
INTRODUCTION: Sedatives applied to cardiac surgery patients can act on the respiratory tract, creating a demand for a tracheal prosthesis in the artificial route, whose distal part (cuff) has a recommended pressure of 20 to 25 mm Hg. The professional's lack of knowledge about procedures and adequate pressure can pose risks to patients' health. OBJECTIVE: To analyze the effect of anesthesiologists awareness on the control of cuff pressure. METHODOLOGY: A prospective cohort study. At the beginning of the research, cuff pressures were consecutively measured immediately after the patient's admission to the intensive care unit (ICU). After this period, anesthesiologists were trained by the responsible researchers for 1 month. In the final 2.5 months of the research, cuff pressure was again measured immediately after the patient's admission to the ICU. RESULTS: A total of 70 patients were evaluated, 37 of whom were pre-awareness and 33 were post-awareness. Male sex was the most prevalent with 46 (66%) patients and the mean age was 58 ± 10 years. There was a reduction from 76 ± 14 to 28 ± 9 in cuff pressure (P < .01). CONCLUSION: The training of anesthesiologists who assist cardiac surgery patients allowed a reduction in cuff pressure abnormalities.
