ClinConnect Summary
This clinical trial is studying how certain changes in blood flow and oxygen levels in the brain occur during a specific type of surgery called laparoscopic cholecystectomy, which is commonly performed to remove the gallbladder. The researchers want to understand how a technique called pneumoperitoneum, which involves inflating the abdomen with gas to allow better access to the organs, affects blood flow in the brain. They will use two different methods, Near-Infrared Spectroscopy (NIRS) and Transcranial Doppler (TCD) ultrasonography, to measure these changes and see if one method is more effective than the other.
To participate in this trial, you need to be between 18 and 65 years old and scheduled for this type of surgery. The study is looking for patients in good health (classified as ASA 1-3), meaning they have no serious health issues. However, individuals with certain medical conditions, such as severe heart or vascular diseases, or those who have had a stroke, cannot participate. If you join the study, you can expect to have your brain's blood flow and oxygen levels monitored during your surgery to help researchers gather important information that may improve patient care in the future.
