Investigating how serum calcium levels affect pain after abdominal surgery
The Effect of Serum Calcium Levels on Postoperative Pain in Patients Undergoing Abdominal Surgery: A Prospective Observational Study
The Second Affiliated Hospital of Chongqing Medical University · NCT06957158
This study is testing if changes in calcium levels in the blood can affect how much pain people feel after having abdominal surgery.

What this trial studies
This prospective observational study examines the relationship between serum calcium levels and postoperative pain in patients undergoing elective abdominal surgery. Researchers will measure total serum calcium and ionized calcium levels before and after surgery, while also recording pain scores at various time points using a numerical rating scale (NRS). The goal is to determine if fluctuations in serum calcium levels can be a risk factor for experiencing postoperative pain.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18-70 who are undergoing elective abdominal surgery and are classified as ASA I-III.
Not a fit: Patients with severe diseases, chronic pain conditions, or those requiring intensive care post-surgery may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management strategies for patients after surgery.
How similar studies have performed: While there have been studies exploring postoperative pain management, the specific focus on serum calcium levels is relatively novel and has not been extensively tested.
