Is this trial a fit for you?
✓Likely a good fit
Adults (18+) with complicated acute appendicitis presenting with generalized peritonitis who understand French, have a smartphone with internet access, and can give informed consent are ideal candidates.
✕Probably not a fit
Patients with intraperitoneal abscess or plastron, sensory or neurological impairments preventing video use, active cancer or immunosuppression, those treated after interval appendectomy, or those without a smartphone or French language ability are unlikely to benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Adults with complicated acute appendicitis and generalized peritonitis who undergo emergency laparoscopic appendectomy at Nice University Hospital will be enrolled. Participants who have a smartphone will view hypnosis videos delivered via their phone during the perioperative period in addition to the center's standard pain management protocols. The study will measure immediate postoperative pain levels, anxiety, opioid and analgesic consumption, and length of hospital stay. Patients with exclusion conditions or who cannot use video on a smartphone will not be included.
Why it matters
Potential benefit: If successful, smartphone-delivered hypnosis could reduce acute postoperative pain and anxiety, lower opioid use, and shorten hospital stays for these patients.
How similar studies have gone: Hypnosis has shown benefit for perioperative pain and anxiety in prior studies, but delivering hypnosis via smartphone for acute post-appendectomy peritonitis is relatively novel.
