Association between body mass index, lactate dehydrogenase, and postoperative pain


  • A high body mass index (BMI) is not associated with higher postoperative pain; however, serum lactate dehydrogenase (LDH) levels may be associated with increased risk of postoperative pain.

Why this matters

  • Obesity is associated with increased general pain; however, it is unknown what effect obesity has on postoperative pain.

  • Understanding the association between obesity and postoperative pain may lead to improved clinical outcomes.
