PARO robotic seal to reduce agitation after visceral surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study introduces the PARO robotic seal to adult patients undergoing elective visceral surgery and monitors patient-robot interactions in the postoperative period. PARO responds to touch, sound, facial expressions and gestures and uses audiovisual recognition, tactile sensors, and embedded AI to engage patients. The study compares the occurrence, duration, and severity of postoperative agitation in a cohort using PARO versus a cohort not using the device. The trial is conducted at the Medical School Hannover with in-person enrollment and follow-up.
