Disritmias cardíacas e alterações do segmento ST em idosos no perioperatório de ressecção transuretral da próstata sob raquianestesia: estudo comparativo
Abstract: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.
Arrhythmias are the most commonly encountered cardiovascular complications during anesthesia administration. Perioperative arrhythmias disrupt the hemodynamic state of the patients and are known to cause increases in mortality and morbidity. Anesthetic agents and methods affect cardiac conduction and cause arrhythmia. At the same time, patients with additional cardiac diseases and other systemic diseases affecting the cardiovascular system have increased risk of perioperative arrhythmia. For the patient, regardless of whether due to the surgical procedure or anesthesia type, the most important effect of intraoperative arrhythmias is undoubtedly the resulting hemodynamic instability. It is possible to encounter a broad range of serious rhythm and hemodynamic disorders from rare ventricular extrasystole to malignant character arrhythmia and sudden cardiac arrest. Temperature changes occurring in the intraoperative period, hypoxia, acid-base disorders and variations in electrolyte balance are significant factors affecting the occurrence of arrhythmia. As there are many factors and mechanisms in the etiology, identifying arrhythmia under anesthesia and performing the necessary intervention in the shortest time possible has vital importance. This review deals with the importance of arrhythmia occurring in the perioperative period and methods of approach for arrhythmia.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
