Abstract

Background: Factors such as abstinence from drinking, fasting, intestinal preparation, and stress responses can contribute to issues like inadequate blood volume, hypoglycemia, and electrolyte imbalances. The ASA classification presently serves as a primary assessment standard globally. In response to prevailing clinical challenges, we propose enhancing the preoperative assessment for elderly patients undergoing painless gastroenteroscopy. This enhancement involves incorporating the Frailty score, bedside ultrasound, and bedside laboratory results alongside the ASA classification, to establish a comprehensive assessment system. This holistic approach aims to monitor patients’ fluid balance, electrolyte levels, and blood glucose changes, facilitating precise interventions and optimized anesthesia strategies. The ultimate goal is to diminish perioperative adverse events, especially those related to the cardiovascular system, thereby enhancing prognosis, outcomes, and patient satisfaction among the elderly.
Methods: This study is a randomized controlled trial conducted at a single center. It includes 204 patients scheduled for painless gastroenteroscopy. Eligible subjects will be randomly assigned to either Group A or Group B. Pre-anesthesia assessments will be conducted twice – during the preoperative visit and upon entry to the endoscopy center on the examination day. Evaluation parameters will encompass the Edmonton Frail Scale (EFS), bedside ultrasound measurements including inspiratory IVCDmax, expiratory IVCDmin, and calculation of the inferior vena cava collapse index (IVC-CI). Additionally, serum electrolyte (potassium) and blood glucose levels will be measured. Patients in Group A will receive specific interventions based on predetermined criteria. The primary endpoint is anesthesia-related adverse events. The measurements will be performed perioperatively, post-treatment, and at 1 day, 3 days, and 7 days after the end of treatment.
