Cardiac arrhythmias and ST changes in the perioperative period of elderly patients submitted to transurethral prostatectomy under spinal anesthesia: comparative study. Rev. Bras. Anestesiol. [online]. 2004, vol.54, n.2, pp. 190-203. ISSN 1806-907X. http://dx.doi.org/10.1590/S0034-70942004000200006.
BACKGROUND AND OBJECTIVES: Elderly account for 25% of surgical patients. Several patients with arterial heart disease have normal preoperative ECG and a high incidence of silent myocardial acute infarction in the first postoperative week. Arrhythmias increase with age and supraventricular and ventricular premature complexes, atrial fibrillation and intraventricular conduction abnormalities are observed. This study aimed at evaluating the prevalence of perioperative arrhythmias and ST changes through Holter System in elderly patients submitted to transurethral prostatectomy and inguinal hernia repair under spinal anesthesia. METHODS: Participated in this study 21 patients aged 65 to 84 years submitted to transurethral prostatectomy (TUP) and 16 patients aged 63 to 86 years submitted to inguinal hernia repair under spinal anesthesia. Monitoring with Holter System was performed in the preoperative (12 hours), intraoperative (3 hours) and postoperative (12 hours) periods. RESULTS: The prevalence of supraventricular premature complex was 85.7% vs. 93.7% in the preoperative period, 85.7% vs. 81.2% in the intraoperative and 76.2% vs. 100% in the postoperative period, respectively for groups TUP and control. The prevalence of ventricular premature complex was 76.2% vs. 81.2% in the preoperative period, 80.9% vs. 68.7% in the intraoperative period, and 80.9% vs. 81.2% in the postoperative period, respectively for groups TUP and control. The prevalence of ST changes was 19% vs. 18.7% in the preoperative period, 4.7% vs. 18.7% in the in the intraoperative period, and 14.3% vs. 18.7% in the postoperative period between groups TUP and control, without statistical significance. CONCLUSIONS: Elderly patients have a high prevalence of supraventricular and ventricular cardiac arrhythmias. The total number of preoperative arrhythmias and ST changes was not changed as a function of transurethral prostatectomy surgery or inguinal hernia repair, in the intra and postoperative periods.
