To evaluate the quality of successful ultrasound guided supraclavicular brachial plexus block and its correlation with perfusion index ratio
Keywords:
supraclavicular brachial plexus, perfusion index ratio, upper limbAbstract
Background: Ultrasound-guided supraclavicular nerve block is a popular approach for anesthesia for upper limb surgeries. Perfusion index can considered as an objective measure for peripheral perfusion that can predict peripheral block success. Early and accurate detection of peripheral block success would enable rapid corrective action this would save the operating room time and improve patient satisfaction. The main objective was to evaluate the quality of supraclavicular brachial plexus block and it’s correlation with Perfusion Index ratio. Method: It was a prospective observational study carried out over a period of 18 months from November 2018 to April 2020 in the department of anesthesia. Patients aged between 18 to 65 years. Written informed consent, 30 patients of either sex, belonging to ASA grade I and II, scheduled for elective upper limb, under supraclavicular brachial plexus block were selected for the study. Quality of block was made on the basis of 3 point scale. Result: In this study we observed that the Perfusion index was significantly higher in blocked limbed at all time points.
