Official title:
Pain Sensitivity and Outcome in Arthroscopic Shoulder Surgery
The purpose of this study is to investigate whether there is a correlation between a patients pain sensitivity and their subsequent post-operative pain and surgical outcome in arthroscopic shoulder surgery.
Arthroscopic shoulder surgery is increasingly performed on a daycase basis. Optimal pain
relief is the goal as this not only improves patient comfort and allows expedient discharge
from hospital, but also reduces the risk of developing postoperative chronic pain and may
improve surgical outcome. However, optimal postoperative pain control in daycase surgery
remains a challenge. There is considerable variation in the level of postoperative pain
experienced between individuals and subsequent analgesia requirements. Previous studies have
attempted to predict the level of postoperative pain an individual will experience, using a
variety of complex preoperative pain and psychological assessments. Other investigators have
focused on a simpler approach, by testing an individual's pain threshold to a single
preoperative nociceptive (painful) stimulus, e.g. heat or pressure. Recent work has produced
a simple questionnaire alternative to pain intensity testing, the Pain Sensitivity
Questionnaire (PSQ). We hypothesise that a patient's pain sensitivity preoperatively may
both affect the level of pain they experience postoperatively and their final surgical
outcome.
The aim of our study is to correlate a patient's pain sensitivity, as measured by the Pain
Sensitivity Questionnaire, with the degree of acute postoperative pain (first 4 days) they
experience and subsequent surgical outcome at 6 months.
