About

The PABLOS study (NCT05345639) recently realised at the University Hospital of Angers looked at the place of loco-regional anesthesia (LRA) in the optimization of analgesia and the early post-operative recovery of patients operated from cardiac surgery by sternotomy.

All randomized patients (n=253) were followed for 30 days as part of PABLOS monitoring with the aim of optimizing acute care.

However, sternotomy surgery causes chronic pain with neuropathic components. Indeed, numerous recent studies suggest that cardiac surgery by median sternotomy is associated with the development of chronic sternal pain with an incidence of 11% to 56% one year after surgery. Most patients with chronic post-sternotomies pain report mild pain (1 to 3 on the Numerical Scale), however, up to 18% report moderate to severe pain (4 to 10 on the EN).

It therefore seems important to the investigator to evaluate the prevalence of chronic post-sternotomies pain within our PABLOS cohort and to know whether performing a post-operative LRA limits their occurrence.

Full description

PABLOS 2.0 is a non-interventional cohort study with prospective data collection by telephone questionnary, with three groups from a single-center superiority interventional study. Patients remained blinded for the duration of the study.

The patients in the cohort come from the precedent PABLOS study (NCT05345639). They receive oral and written information, and confirm orally their non-opposition to participating in the PABLOS 2.0 study.

The specific procedures of the PABLOS 2.0 study are the collection using a telephone questionnary of the score of the numerical scale (from 0 to 10) of pain at rest and with effort, of the DN4 (proportion of chronic pain with a neuropathic component), of the EQ-5D-5L scale (quality of life) and of consumption of painkillers.
