Researchers conducted a randomized trial to compare two ways of delivering ropivacaine, a numbing medication, to patients undergoing open heart surgery. The study focused on whether giving the medicine in intermittent boluses was more effective than a continuous infusion through a specific type of catheter called an ESP catheter.
The study included 240 adults in a large academic hospital. The results showed that patients receiving the intermittent boluses used slightly more opioid medication over 72 hours than those receiving the continuous infusion. However, this difference was not statistically significant, meaning the two methods performed similarly in practice.
Other measures, such as pain intensity, length of stay in the hospital, and the time to the first bowel movement, showed no significant differences between the two groups. Because the results were so similar, the study suggests that both methods of delivering the numbing medication are comparable for managing early pain after heart surgery.
Common questions
How did the two treatment methods compare?
The study compared giving ropivacaine in intermittent boluses versus a continuous infusion. While the group receiving intermittent boluses used 1.08-fold more opioid medication over 72 hours, the difference was not statistically significant. This means both methods were similar in how they managed pain after heart surgery.
Did the method of delivery affect how long patients stayed in the hospital?
No, the study found no statistically significant differences between the two groups regarding the length of stay in the hospital. Other factors, such as pain intensity and the time to the first bowel movement, also showed no significant differences between the two delivery methods.
Is one method better for managing pain after heart surgery?
The study did not find one method to be significantly better than the other. Both the intermittent bolus and the continuous infusion methods resulted in similar outcomes for pain intensity and quality of recovery. You should talk to your doctor about which pain management plan is best for your specific needs.
