Background and Aims Minimally invasive cardiac surgery (MICS) has emerged as a promising approach for cardiac procedures, improving patient outcomes. However, postoperative pain management remains a significant challenge in this field. Various regional anesthesia techniques have been investigated with the erector spinae plane block (ESPB) being one of the relatively recent advancements. Our aim is to compare the efficacy of this block with a control group in patients undergoing MICS.
Methods PubMed, EMBASE, and Cochrane were searched for studies comparing the ESPB to control (non-block group). The outcomes included opioid consumption, postoperative duration of mechanical ventilation, and intensive care unit (ICU) and hospital lengths of stay. RevMan 5.4 analyzed data.
Results The present study systematically analyzed a total of six studies encompassing a sample size of 717 patients, with 43.2% of them undergoing the erector spinae plane block (ESPB). Our findings revealed that the implementation of ESPB yielded a statistically significant reduction in the duration of mechanical ventilation when compared to the control group (figure 1). Conversely, no significant differences were observed between the ESPB and control groups in relation to opioid consumption (figure 2). Furthermore, there were no significant disparities detected between the groups concerning the lengths of stay in the intensive care unit (ICU) and hospital (figure 3).
Conclusions Based on our findings, it can be inferred that the implementation of the ESPB may effectively decrease the duration of mechanical ventilation. However, in order to draw more comprehensive conclusions, further investigations involving a larger number of patients are warranted.
