Arritmias e alterações do segmento ST em idosos no perioperatório de ressecção transuretral da próstata sob raquianestesia

Abstract

Objective: evaluate the prevalence of cardiac arrhythmias and ST changes during the preoperative, intraoperative e postoperative periods through the electrocardiographic Holter monitoring in aged patients undergoing transurethral prostatectomy and inguinal herniorraphy under spinal anaesthesia. Patients and Method: 21 patients with benign prostatic hyperplasia and 16 with inguinal hérnia, aged 63 to 86 years, negative sorology to Chagas disease, submited to transurethral prostatectomy and inguinal hérnia repair under sipinal anaesthesia. They were evaluated with clinicai exam, laboratory and electrocardiographic tests. Ambulatory ECG Holter was used during the preoperative (12 hours), intraoperative (3 hours) and postoperative (12 hours) periods. Results: there was no difference between groups in age average (p=0,246). The prevalence of bradicardia among RTU group and control was, in the preoperative period, (85,71% vs. 75%), in intraoperative period (95,23% vs. 68,75%) and Postoperative (85,71% vs. 68,75%), without statistical significance. The prevalence Of supraventricular arrhythmias was (85,71% vs. 93,75%) in the preoperative period, (85,71% vs. 81,25%) in the intraoperative and (76,19% vs. 100%) in the postoperative, that was estatistically significant in control group (p=o,015). The prevalence of ventricular arrhythmyas among RTU group and control was, in the preoperative period (76,19% vs. 81,25%), intraoperative (80,95% vs. 68,75%) and postoperative (80,95% vs. 81,25%), without statistical significance.90 The prevalence of ST changes between RTU group and control was, in the preoperative period, (19,05% vs. 18,75%), in the intraoperative (4,75% vs. 18,75%) and postoperative (14,28% vs. 18,75%), without statistical significance. Conclusion: the aged patients have a high prevalence of supraventricular and ventricular cardiac arrhythmias. The total number of arrhythmias and ST changes in the preoperative period was not changed by transurethral prostatectomy surgery and inguinal hérnia repair, in intraoperative and postoperative periods.
