Stability of sufentanil and baclofen mixtures for intrathecal analgesia at different concentrations in polypropylene syringes.

Background: Intrathecal analgesia is a method using various molecules alone or in combination. Among these, the association sufentanil/ baclofen is widely used. Instead of moving patients to the few expert centers taking charge of these specific preparations, it could be better to transport syringes to peripheral centers managing pump refilling.

Validated chromatographic method for the simultaneous determination of eight drugs (morphine, ropivacaine, bupivacaine, baclofen, clonidine, sufentanil, fentanyl and ziconotide) for intrathecal analgesia.

Intrathecal analgesia has increased over the past two decades in various indications: chronic refractory pain from cancerous or non-cancerous origins, spasticity. These different indications involve the use of different molecules alone or in combination such as morphine, ropivacaine, bupivacaine, fentanyl, sufentanil, clonidine, baclofen and ziconotide. Pump refills are prepared at the pharmacy under a laminar flow hood.

[Study of the reproducibility of the sterilization process and proposal of an sterilizer requalification protocol].

Unlike EN 554, and since the publication of ISO 17665-1 standard, the user of autoclaves may use methods other than those indicated in the guidelines. Outsourcing the requalification of sterilizers by an external service provider and after observing from the previous requalification reports that the thermometric data seemed reproducible, we decided to propose and validate a validation method for the reproducibility of the sterilization process. This is to exempt from the study of the repeatability of the EN 554 standard in future requalifications.
