Post-Operative Pain Management

Pain after surgery is more than discomfort. It shapes how quickly patients can move, eat, sleep and return to everyday life. Yet many traditional pain regimens rely on opioids, with side effects that slow recovery down rather than support it.

CIMPAX believes there is a better way. Our pain management portfolio is built around Continuous Wound Infiltration (CWI), a targeted technique that delivers local anesthetic directly to the surgical site. The medication works exactly where it is needed, with minimal impact on the rest of the body.

The problem with opioids

Opioids such as morphine and codeine remain widely used after surgery. They are effective at controlling pain, but they bring a long list of unwanted effects: nausea, constipation, drowsiness, respiratory depression, and the risk of dependence.

Post-operative pain itself is also a persistent problem. Studies show it is one of the greatest concerns patients carry into surgery, and inadequate control delays mobilization, prolongs hospital stays, and reduces patient satisfaction.

At the same time, the wider opioid crisis has put pressure on hospitals worldwide to find safer alternatives. In the United States alone, the CDC has reported tens of thousands of opioid-related deaths annually, many traceable to prescriptions that began after surgical procedures.

The clinical case for opioid-sparing recovery has never been stronger.

A better approach: Continuous Wound Infiltration

Local anesthetics offer a fundamentally different approach to post-operative pain. Instead of acting on the whole body, they block pain signals at the source. The challenge has always been delivery: getting the right medication to the right place, reliably, over time.

That is what CWI solves. A thin, multi-hole catheter is placed by the surgeon or anesthesiologist during the procedure, either directly in the wound or near the relevant nerve. A portable infusion pump then delivers local anesthetic at a steady, continuous rate for as long as it is needed.

The result is precise, site-specific pain relief with significantly fewer systemic side effects.

What this means for patients and hospitals

Improved analgesia at the source – Local anesthetic acts directly where it is needed, with predictable efficacy.

Reduced opioid consumption – Patients need fewer narcotics, with all the safety and recovery benefits that brings.

Fewer side effects – Less nausea, less drowsiness, less post-operative ileus, lower risk of respiratory complications.

Easier mobilization – Better pain control means patients can get up, move and start recovering sooner.

Faster recovery and shorter stays – Aligns with Enhanced Recovery After Surgery (ERAS^®) protocols and supports earlier discharge.

Higher patient satisfaction – Comfortable, opioid-sparing recovery is consistently rated higher in patient-reported outcomes.

Our solution: the CIMPAX C-CAT system

The CIMPAX^® C-CAT system makes CWI practical, reliable and easy to integrate into surgical workflows. It is built from components that work together as a complete therapy, or independently with compatible third-party systems.
