Description
Mangabeira and colleagues compare two pain-control methods for cats having spay surgery, in a 2026 randomized, blinded animal anesthesia trial. Twenty female cats received a lumbosacral epidural, numbing drug injected near the spinal cord, or quadratus lumborum blocks, ultrasound shots into a muscle layer, using levobupivacaine. Heart and breathing measures were recorded at seven time points. Pain was scored for 6 hours afterward on a pain scale, with methadone on hand as rescue relief.
No real differences appeared in any heart-lung variable between the two methods during surgery. Anesthetic infusion rates were similar, at 0.36 against 0.39 milligrams per kilogram per minute for the epidural and block groups. Pain scores after surgery did not differ, and no cat needed rescue analgesia. Only one cat, in the block group, needed methadone, at the 6-hour check. Mangabeira concludes the ultrasound block matches the epidural, a useful alternative when a spinal shot is impractical.
