Cold therapy for the management of pain associated with deep breathing and coughing post-cardiac surgery.

Abstract

Background: Coughing has been identified as the most painful experience post cardiac surgery.

Methods: Participants (n = 32), in a randomized crossover trial, applied a frozen gel pack to their sternal incision dressing before performing deep breathing and coughing (DB & C) exercises. Pain scores from 0 to 10 at rest were compared with pain scores post DB & C with and without the gel pack. Participants were also asked to describe their sensations with the frozen gel pack, as well as their preferences for gel pack application.

Results: The repeated measures analysis of variance revealed a significant reduction in pain scores between pre- and post-application of the gel pack (F = 28.69, p < .001). There were 22 (69%) participants who preferred the application of the gel pack compared with no gel pack. All 32 (100%) participants would reapply the gel pack in the future.

Conclusion: This study demonstrates that cold therapy can be used to manage sternal incisional pain when DB & C.
