Abstract
Background:
Thoracic epidural analgesia is the gold standard for major thoracic and abdominal surgeries.
Aim:
Ultrasound-guided and landmark-based thoracic epidural insertion are compared in this systematic review.
Methods:
Randomised controlled trials were sought in six databases for a systematic review and meta-analysis. With a 95% confidence interval, a fixed-effects model calculated risk ratio or mean difference. Cochrane risk of bias assessed bias. Four randomised controlled trials were examined.
Findings:
Preprocedural ultrasound increased thoracic epidural placement first-puncture success rate (risk ratio = 1.28, 95% confidence interval (1.05 to 1.56), p value = 0.02) and decreased the need for two or more skin punctures (mean difference = −2.41, 95% confidence interval (−3.34 to −1.47), p value = 0.00001). The ultrasound group reduced needle redirections (risk ratio = 0.6, 95% confidence interval (0.38 to 0.94), p value = 0.02). The epidural block success rate was equal in both groups (risk ratio = 1.02, 95% confidence interval (0.96 to 1.07), p value = 0.6).
Conclusion:
Thoracic epidural insertion is improved by ultrasound but not the success rate. Quality research with larger samples is needed to emphasise these conclusions.
