Abstract
Objective: This study investigates the impact of preoperative fasting time on patients undergoing partial nephrectomy and analyzes the risk factors for postoperative hemorrhage to provide clinical reference for physicians treating patients undergoing partial nephrectomy.
Methods: A retrospective analysis was conducted on 74 patients who underwent partial nephrectomy for renal tumors between January 2022 and March 2024. Baseline and perioperative data were collected. The effects of long-term and short-term preoperative fasting on patients undergoing partial nephrectomy were compared. Additionally, univariate and multivariate logistic regression analyses were performed to identify risk factors for hemorrhagic complications following partial nephrectomy.
Results: Among the patients in this study, 26 (35.14%) underwent short-term preoperative fasting, while 48 (64.86%) underwent long-term preoperative fasting. The hemoglobin difference in the short-term fasting group was 21.08 ± 12.44 ml, compared to 13.65 ± 11.69 ml in the long-term fasting group, showing a statistically significant difference (p = 0.020). Differences in serum calcium (p = 0.003), serum magnesium (p = 0.031), and serum phosphorus (p = 0.001) between the short-term and long-term fasting groups were also statistically significant. Univariate and multivariate regression analyses identified the type of surgery (p = 0.050) and preoperative fasting time (p < 0.001) as independent risk factors for postoperative hemorrhage following partial nephrectomy.
Conclusion: Patients undergoing partial nephrectomy with short-term preoperative fasting experience a more significant decrease in hemoglobin compared to those with long-term fasting. The type of surgery and preoperative fasting time are independent risk factors for postoperative hemorrhage in patients undergoing partial nephrectomy.
期刊介绍：
Evidence of surgical interventions go back to prehistoric times. Since then, the field of surgery has developed into a complex array of specialties and procedures, particularly with the advent of microsurgery, lasers and minimally invasive techniques. The advanced skills now required from surgeons has led to ever increasing specialization, though these still share important fundamental principles.
Frontiers in Surgery is the umbrella journal representing the publication interests of all surgical specialties. It is divided into several “Specialty Sections” listed below. All these sections have their own Specialty Chief Editor, Editorial Board and homepage, but all articles carry the citation Frontiers in Surgery.
Frontiers in Surgery calls upon medical professionals and scientists from all surgical specialties to publish their experimental and clinical studies in this journal. By assembling all surgical specialties, which nonetheless retain their independence, under the common umbrella of Frontiers in Surgery, a powerful publication venue is created. Since there is often overlap and common ground between the different surgical specialties, assembly of all surgical disciplines into a single journal will foster a collaborative dialogue amongst the surgical community. This means that publications, which are also of interest to other surgical specialties, will reach a wider audience and have greater impact.
The aim of this multidisciplinary journal is to create a discussion and knowledge platform of advances and research findings in surgical practice today to continuously improve clinical management of patients and foster innovation in this field.
