Sublingual Sufentanil PCA Usability for Postoperative Pain (Zalviso® System)

Hospices Civils de Lyon119 enrolled

Overview

Intravenous patient-controlled analgesia (iv-PCA) is the gold standard for the treatment of moderate to severe postoperative pain. It is used in more than 20% of cases after major surgery. Well known disadvantages of this method include the need of intravenous line (invasive, infection risk), the risk of pump programming error, possible delay for ambulation/barrier for enhanced rehabilitation programmes, and time/resource demanding (the need of preparation and installation). Sublingual sufentanil based PCA (Zalviso®) addresses cited issues. The safety and analgesia efficiency of this system is well described. However, the usability and satisfaction of Zalviso® varies depending on clinical settings. The goal of this study is to evaluate the usability and satisfaction of patients, nurses, and physical therapists using Zalviso® System during the first 72 hours in the settings of Enhanced Recovery After Surgery protocol after major interventions associated with moderate to severe postoperative pain.

Interventions

Zalviso Device

The Zalviso device will be provided immediately before the Post anesthesia care unit (PACU) discharge. Patients will be queried every day during three postoperative days for the ability to use the device, their satisfaction, the level of pain, and the incidence of side effects. There will be no changes in usual care. In the end of this study ward nurses carrying Zalviso patients will be asked to provide their usability and satisfaction evaluation for Zalviso device management. Physical therapist will be asked to provide their satisfaction regarding patients' ability to follow physical therapy program.

Outcomes

Primary Outcomes

System Usability Score

A 10 items Licket type System Usability Score will be used in patients with ZALVISO® analgesia and in carrying ward nurses 72 hours the surgery per each case.

Time frame: 72 hours after use of Zalviso

Secondary Outcomes

Satisfaction Score

100 points (0 - no satisfaction; 100 - entire satisfaction) satisfaction score will be used in physical therapist 72 hours after the surgery per each case.
