Abstract
Background: Supraclavicular brachial plexus block is a common type of regional anaesthesia used during hand surgeries. Assessment of block success can be done using traditional methods as pin prick test for sensory assessment, however these traditional methods are time consuming and need patient cooperation which not applicable under general anesthesia. Peripheral perfusion index is a useful non invasive tool for evaluation of block success.
Objective: To predict successful supraclavicular brachial plexus block using peripheral perfusion index instead of traditional assessment of sensory and motor function.
Patients and Methods: A sample of 43 patients were selected according to our inclusion and exclusion criteria from population of patients undergoing elective hand surgeries at El-demerdash Hospital of Surgery during the study period.
Results: Perfusion index (PI) can be used as a predictor for supraclavicular brachial plexus block success in patients undergoing elective hand surgeries. PI of 3 and PI ratio of 2.2 after 10 min are accurate predictors for block success. Patients with PI of > 3 and PI ratio of > 2.2 have successful supraclavicular brachial plexus block when compared with those with PI < 3 and PI ratio< 2.2. Hence, peripheral perfusion index usage can be recommended in this regard.
Conclusion: Perfusion index (PI) is a useful tool for evaluation of supraclavicular brachial plexus block success. PI of 3 and PI ratio of 2.2 after 10 min are accurate predictors for block success.
