Preoperative Pain Catastrophizing and Its Association With Postoperative Pain After Lower Limb Trauma Surgery

September 6, 2019 updated by: Dr Asish Subedi, B.P. Koirala Institute of Health Sciences

Association of Preoperative Pain Catastrophizing With Postoperative Pain After Lower Limb Trauma Surgery

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Correlation of preoperative pain catastrophizing scale (PCS) scores with maximum pain severity at 24 hrs post-operatively.
Time Frame: 24 hours postoperatively
Correlation of preoperative pain catastrophizing scale scores with maximum pain severity at 24 hrs post-operatively. PCS consists of 13 items rated on a 5-point Likert scales from 0 (never) to 4 (all the time) points. The total score for the PCS is 52, with points more than 24 indicating a high level of catastrophizing. Worst or maximum pain intensity during the first 24 hours after surgery is assessed on an 11-point numerical rating scale (NRS). Pain is rated on a 0 to 11 NRS, with 0="no pain" or and 10=pain "as bad as you can imagine."
24 hours postoperatively

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Correlation between preoperative pain catastrophizing scale (PCS) scores with total tramadol consumption postoperatively at 24 hrs
Time Frame: 24 hrs postoperatively
Correlation between preoperative pain catastrophizing scale scores with total tramadol consumption postoperatively upto 24 hrs. PCS consists of 13 items rated on a 5-point Likert scales from 0 (never) to 4 (all the time) points. The total score for the PCS is 52, with points more than 24 indicating a high level of catastrophizing.
24 hrs postoperatively
Correlation of preoperative pain catastrophizing scale (PCS) scores with risk factors for severe pain postoperatively
Time Frame: 24 hrs postoperatively
risk factors include: Age, gender, BMI, socio-economic condition, preoperative anxiety
24 hrs postoperatively
