Wound catheter shows shorter hospital stay after abdominal surgery

This research combined results from several studies to compare two pain control methods after major abdominal surgery. It looked at 778 patients who received either a wound infusion catheter or an epidural for pain relief after a midline laparotomy. The main finding was that patients with a wound catheter had a shorter hospital stay by about half a day. Pain scores at rest and morphine use were similar between the two groups. A subgroup analysis suggested wound catheters might offer slightly better pain control with movement two days after surgery, but this finding is from a smaller group and needs more research. There were no significant differences in safety issues like respiratory depression or catheter problems. The main reason to be careful is that the better pain control with movement came from a subgroup analysis, which is less reliable than the main results. Readers should know that wound catheters appear to provide comparable pain relief to epidurals and may allow patients to go home sooner, but the evidence is not yet practice-changing.
