How surgery timing affects blood clotting
Part of Blood & lymphatic, Cancer clinical trials.
This study looks at how the time of day (morning vs. evening) affects blood clotting during surgery for digestive tract tumors. It may help doctors better manage bleeding risks for patients like you.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 20 and 70 years old.
- You are having surgery for a digestive tract tumor (stomach, intestines, etc.).
- Your surgery starts either in the morning (8–9 AM) or in the evening (7–8 PM).
- Your overall health is good (classified as ASA I or II).
- You have not had blood clots or taken blood thinners (except aspirin stopped a week before).
- You do not have diabetes, low red blood cell count (hemoglobin below 90), and have not needed ICU care after surgery.

This study looks at how bleeding problems in patients with cancer affect the body's ability to break down blood clots. Researchers hope to find better ways to manage and treat these complications.
This study looks at how cancer and surgery affect blood clotting. It may help doctors understand and prevent blood clots in patients having surgery for certain cancers.
This study looks at how the time of day you receive your blood thinner shot affects how well it works in preventing blood clots in the hospital. It may help doctors find the best time to give this medicine to trauma patients.
This study looks at a special blood test (called thromboelastography) that checks how well your blood clots. The goal is to see if this test can predict how the surgery goes and whether you might get a blood clot after surgery. If you join, the test will be done before and after your brain surgery, and you will be monitored for any blood clot complications.
This study is testing a new device that may quickly measure how well your blood clots while you are on a blood thinner. They will take a small blood sample to see if the device works well for patients like you.
This trial tests two ways to prevent blood clots (deep vein thrombosis and pulmonary embolism) after colorectal cancer surgery. The study aims to find out if a new method is as good as the standard one, which could help reduce the risk of these serious complications.
