ClinConnect Summary

This clinical trial is studying two methods for monitoring a patient’s fluid status during surgery, specifically for those undergoing laparoscopic surgery for gastrointestinal tumors. The researchers want to compare a traditional method called FloTrac, which involves a small device placed in the body to measure heart function and fluid levels, with a newer, non-invasive method called Thoracic Electrical Bioimpedance. This new method uses sensors on the skin to gather similar information without needing any invasive procedures.

To be eligible for this trial, participants should be between the ages of 18 and 65 and be scheduled for elective laparoscopic surgery. They should also have a body mass index (BMI) between 18 and 30 and not have certain health issues, such as severe heart or liver problems. If chosen to participate, individuals can expect to have their heart function and fluid responsiveness measured using both techniques during their surgery. It's important to note that this trial is not yet recruiting participants, so there may be a wait before it starts.
