Pre-Operative Diet for Vascular Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
A randomized, controlled trial to evaluate patient compliance and biologic mechanisms of a short-term pre-operative Protein-Calorie Restriction (PCR) diet in comparison to a normal ad libitum diet for 4 days before elective vascular surgery involving a major operation. After a pilot study exploring the safety and feasibility of the PCR diet conducted inpatient before carotid endarterectomy titled Short-Term Endogenous Hydrogen Sulfide Upregulation, and a follow-up study titled Dietary Restriction in Vascular Surgery, the investigators now aim to expand the study to at home diet among a variety of vascular surgery procedures. This study will further elucidate not only the practicality of pre-operative short term dietary restriction, but also provide early data to inform biologic mechanisms and to inform future efficacy trails.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
How does the treatment Scandi-Shake differ from other treatments for vascular disease?
The treatment Scandi-Shake, used as part of a pre-operative diet, focuses on reducing calorie and protein intake to decrease surgery-related risks by improving metabolic fitness and insulin sensitivity. This approach is unique as it aims to modulate the body's response to surgical stress, unlike other treatments that may not specifically target dietary changes before surgery.12345
What data supports the effectiveness of the treatment Scandi-Shake for vascular disease?
Research suggests that short-term dietary interventions, like protein-calorie restriction, can improve surgical outcomes by reducing complications and enhancing recovery in vascular surgery patients. Additionally, targeted nutritional support has been shown to improve nutritional status and reduce hospital stays in similar surgical contexts.15678
