Frailty among patients undergoing surgery is strongly associated with an elevated risk of adverse perioperative outcomes, heightened incidence of postoperative complications, increased mortality rates, and prolonged hospital length of stay. Our focus centers on investigating the frailty index in the context of complications experienced by patients undergoing oncologic gynecology surgery. The principal objective of this research is to elucidate the extent to which residual neuromuscular blocking agents are linked to frailty.
Among patients undergoing oncologic gynecological procedures, such as those for vulvar cancer, endometrial cancer, and ovarian cancer, the incidence of frailty has been observed to range from 14% to 45%. Frailty directly influences the metabolism of anesthetic agents and intraoperative management. Furthermore, the prevalence of residual neuromuscular blocking agents following surgery can be as high as 26% to 53%. No prior research has investigated the correlation between residual muscle relaxants and frailty in gynecologic oncology patients. This study is designed to assess the prevalence of residual muscle relaxants in these patients with frailty. Additionally, data on the incidence of frailty and its impact on postoperative outcomes and prognosis in patients undergoing gynecologic oncology surgery will be collected and reported.
