Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The Pain Catastrophizing Scale (PCS) is a psychometric tool to identify PC. A positive correlation between PCS scores and various pain outcomes has been reported in acute and chronic pain settings. Preoperative catastrophizing is associated with an increased intensity of postoperative pain and more analgesic consumption. Likewise, a recent meta-analysis revealed that PC is a strong predictor of persistent postsurgical pain. The Nepali version of PCS has been validated recently in patients with chronic pain. However, it has not been used in patients with acute pain. Therefore, our aim is to assess the relationship between preoperative Nepali PCS (N-PCS) scores and postoperative pain intensity and total opioid consumption in patients with musculoskeletal trauma planned for surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

After approval from Institute Review Committee, we will assess eligibility of patients admitted in-patient-unit of orthopaedic ward planned for lower limb trauma surgery under spinal anesthesia. Recruited patients will be counseled and informed about the study and information sheet and consent form provided. Will obtain consent from the participant. patients will be asked to complete N- PCS questionnaire preoperatively a night before surgery in patient unit. On arrival to the operating room, standard monitoring will be applied. All the patients will receive spinal anaesthesia with 2.6 ml of hyperbaric bupivacaine (0.5%) and fentanyl 20 µg. NRS scale will be used to assess the intensity of their pain postoperatively on arrival to Post-anesthesia care unit, at 2, 4, 6, 12 h and 24 h after the end of surgery. One gram paracetamol IV and Ketorolac 30 mg IV will be given at the end of surgery and continued at 6 and 8 h intervals postoperatively. If the Numeric rating scale (NRS) for pain is \> 3 at rest, tramadol 50 mg IV bolus administered, and repeated at 10 min intervals until NRS was ≤ 3 for the first 24 h. Patients will be asked to rate their worst or maximum pain intensity during the first 24 hours after surgery, on an 11-point numerical rating scale. Socio-demographic variables (age, BMI, ethnicity, gender, socio-economic status, occupation and education), preoperative anxiety of the participant will be recorded.
