Brief summary

Following arthroscopic shoulder surgery a small but significant number of people suffer severe postoperative pain. This study aims to predict which patients are at risk of developing severe post operative pain so that they may be targeted with a more aggressive post operative pain regimen.

Detailed description

Patients presenting for elective (day case) arthroscopic shoulder surgery for either Arthroscopic Subacromial Decompression (ASD Group) or Rotator Cuff Repair (RCR Group) are recruited. Using a Cefar PainMatcher, a pain and sensory threshold assessment tool, consenting patients will have their preoperative pain thresholds recorded. The patients will then have a standard anaesthetic administered with TIVA (propofol/remifentanil) and either a subacromial injection (ASD Group) or interscalene block (RCR Group). Four days following surgery a telephone questionnaire will be completed by the patients recording their worst pain score since surgery.

Interventions

DEVICEElectrical pain threshold measurement

Assessment of preoperative pain threshold using electrical stimulation using a Painmatcher machine.

DEVICEMeasurement of electrical pain threshold

Measurement of preoperative electrical pain threshold and self reporting of postoperative pain scores (for 4 days) on VAS.

Measure	Time frame	Description
Post operative pain level	4 days	Post operative pain level recorded on a VAS (0-10) at rest and movement for the first four days pots shoulder surgery. This information will be correlated with the preoperative pain threshold of patients taken with the Pain matcher machine.
