Intercostal nerve block effective as epidural analgesia post thoracotomy
A new study by Zangong Zhou and team showed that after a thoracotomy, intercostal nerve block (ICB) may be just as helpful in relieving pain as Epidural analgesia (EPI). The findings of this study were published in Pain Physician Journal.
Thoracotomy is linked to severe postoperative discomfort. After a thoracotomy, effective pain management may lessen complications and persistent discomfort. Even while epidural analgesia is regarded as the ideal form of pain relief following a thoracotomy, it has drawbacks. An intercostal nerve block offers a minimal risk of serious consequences, according to newly available research. An evaluation of the benefits and drawbacks of ICB and EPI during thoracotomy would be helpful to anesthetists. This meta-analysis examined the effectiveness of ICB and EPI as analgesics and their side effects when used to alleviate pain following thoracotomy.
The International Prospective Register of Systematic Reviews received this study's registration. The databases PubMed, Cochrane, Embase, and Ovid were searched for pertinent papers. Analysis was done on the primary (postoperative pain when coughing and at rest) and secondary (morphine intake, nausea, and length of hospital stay) outcomes. Calculations were made to determine the risk ratio for dichotomous variables and the standard mean difference for continuous variables.
The key findings of this study were:
1. There were 498 individuals who received thoracotomies in nine randomized controlled trials.
2. The meta-analysis's findings showed that there were no statistically significant variations between the 2 procedures in terms of pain levels on the Visual Analogue Scale at 6–8, 12–15, 24–25, and 48–50 hours following surgery when resting and at 24 hours when coughing.
3. The ICB and EPI groups did not vary significantly in terms of morphine intake, nausea and vomiting, or hospital stay duration.
