ClinConnect Summary

This clinical trial is studying how levels of calcium in the blood may affect pain after abdominal surgery. Researchers want to see if changes in these calcium levels can increase the risk of experiencing more pain after the surgery. The trial is currently looking for participants aged 18 to 70 who are scheduled for elective abdominal surgery and are generally healthy. To join, individuals must be able to understand the study and give their consent.

If you or someone you know is eligible and decides to participate, you can expect to have your calcium levels measured before and after surgery. This information will help researchers determine if there is a link between calcium levels and postoperative pain. It's important to note that those with certain health conditions, including severe diseases or those who have ongoing pain issues, may not be able to participate. By taking part in this study, you could help doctors better understand how to manage pain after surgery for future patients.
