Does Preoperative Vitamin D Level Effect Acute Postoperative Pain After Hip Arthroplasty Surgery

Abstract

Objective: 25-OH Vitamin D is well known that has an important role in the perception of pain. Vitamin D insufficiency is important health problem all over the world. Most of the research related to vitamin D and pain is about chronic pain. In this study, it was investigated whether there is an association between Vitamin D levels and acute postoperative pain.Methods: Preoperative Vitamin D levels were measured in patients who underwent elective hip replacement. Patients undergoing spinal anesthesia were administered patient-controlled analgesia (PCA). Patients whose pain assessment was performed with the postoperative visual analog scale (VAS), the time of initial analgesic administration, the number of analgesic needs, the number of bolus opioid use and additional NSAID use were evaluated. Results: It has seen that a negative correlation between the vitamin D values and postoperative VAS scores. It was determined that patients with low vitamin D had earlier postoperative first analgesic administration time. It was also determined that as the vitamin D values decreased, the number of bolus opioids and total analgesic requirements used was higher. Conclusion: In postoperative pain, low preoperative vitamin D level caused an increase in VAS scores and analgesic need and patients have low vitamin D also had earlier analgesic administration time.
