Pain relief following sternotomy in conventional cardiac surgery: A review of non neuraxial regional nerve blocks

Acute post-operative pain following sternotomy in cardiac surgery should be adequately managed so as to avoid adverse hemodynamic consequences and pulmonary complications. In the era of fast tracking, adequate and efficient technique of post-operative analgesia enables early extubation, mobilization and discharge from intensive care unit. Due to increasing expertise in ultrasound guided blocks there is a recent surge in trial of bilateral nerve blocks for pain relief following sternotomy. The aim of this article was to review non-neuraxial regional blocks for analgesia following sternotomy in cardiac surgery. Due to the paucity of similar studies and heterogeneity, the assessment of bias, systematic review or pooled analysis/meta-analysis was not feasible. A total of 17 articles were found to be directly related to the performance of non-neuraxial regional nerve blocks across all study designs. Due to scarcity of literature, comments cannot be made on the superiority of these blocks over each other. However, most of the reviewed techniques were found to be equally efficacious or better than conventional and established techniques.
