Meta AnalysisThe efficacy of Perfusion Index for identifying failed nerve block in patients receiving upper extremity surgery: a meta-analysis.
Nerve block success is commonly assessed through a variety of techniques, including testing sensations for temperature over the relevant dermatomes and evaluating pain response (e.g., pin-prick). This meta-analysis aimed to investigate the diagnostic efficacy of Perfusion Index (PI) in identifying failed nerve blocks in patients undergoing upper extremity surgery. ⋯ Our meta-analysis confirmed that the PI values and ratios are promising objective predictors of nerve block failure. The simplicity of these techniques supports their feasibility for routine clinical practice. Further studies focusing on different patient populations, such as pregnant women or the elderly, are needed to validate and expand upon our findings.
