Whether intense pain before emergency surgery leads to long-term pain after the operation
Acute Preoperative Pain and Chronic Post-surgical Pain in Emergency Surgery
We will test whether people having emergency abdominal or orthopedic surgery who have strong pain before the operation are more likely to have ongoing pain three months afterward.

What this trial studies
Adults undergoing emergency abdominal or orthopedic surgery at a single university hospital will report their preoperative pain intensity using a numerical scale. Data will be collected with questionnaires and follow-up phone calls, and outcomes will include the presence of chronic postsurgical pain at three months. Patients requiring postoperative ICU, undergoing ambulatory or endoscopic procedures, or unable to self-report pain are excluded. The study is conducted at CHU Amiens-Picardie with enrollment limited to patients able to consent and communicate in French.
Who should consider this trial
Good fit: Adults (age ≥18) having emergency orthopedic or abdominal surgery who can give informed consent, communicate in French, self-rate pain, and are affiliated with a social security scheme are ideal candidates.
Not a fit: Patients admitted to postoperative intensive care, having ambulatory or endoscopic procedures, repeat surgery at the same site within three months, pregnant or breastfeeding individuals, those with significant psychiatric or neurodegenerative disorders, or those unable to self-report pain are unlikely to benefit from this study's findings.
Why it matters
Potential benefit: If successful, this could help identify patients at higher risk of chronic postsurgical pain so clinicians can target prevention and pain management earlier.
How similar studies have performed: Previous work in scheduled surgery links preoperative pain to worse short-term postoperative pain, but the long-term effects of acute preoperative pain in emergency surgery remain largely untested.
