Estudo prospectivo das repercussões de baixas doses de remifentanil na função sinoatrial e na condução e refratariedade cardíaca

Abstract: ), após 5 minutos (M0) avaliou-se o grau de sedação de intensidade de dor, pressões arteriais sistólica e diastólica, freqüências cardíaca e respiratória e saturação de oxigênio. O eletrofisiologista avaliou as variáveis de condução cardíaca (duração do QRS, intervalos AA, AH, HV e PA), o tempo de recuperação do nódulo sinoatrial e as variáveis de refratariedade cardíaca (período refratário do átrio direito, período refratário do ventrículo direito e período refratário do nódulo atrioventricular). Após as medi… Show more

“…The higher doses of remifentanil in the latter group justify this effect. Leite et al 17 used low doses of remifentanil in 16 patients undergoing electrophysiologic study and concluded that this drug would not be ideal for this type of procedure because it produced a delay in cardiac conduction and refractoriness. The results obtained in this study, corroborating Leite et al, demonstrated that remifentanil used in low doses (0.025 to 0.075) may have altered atrial electrical properties.…”

“…The literature, however, is scarce 8 as for research that discuss advantages and disadvantages of the techniques, as well as to the establishment of specific guidelines on the subject. Most works show how the anesthetic technique used intravenous sedation (conscious or unconscious), based on the preference of the anesthesiologist or institutional protocols [14][15][16][17] . This study aims to compare the techniques of deep sedation and general anesthesia for curative ablation of atrial fibrillation and evaluate the hemodynamic and respiratory parameters, complications, and recurrence (outcome).…”
