Brief Summary:
This study was designed to determine whether the success or failure of interscalene brachial plexus block under general anesthesia can be predicted using perfusion index (PI).
Detailed Description:
The success of peripheral nerve blocks is usually evaluated by assessment of sensory and motor function; however, this method cannot be applied in the patient who has uncheckable mental status, e.g. general anesthesia, or who is uncommunicable, e.g. different language user.
The perfusion index (PI) is a numerical value for the ratio between pulsatile and non-pulsatile blood flow measured by a special pulse oximeter, and PI had been proved as a useful tool for evaluation of successful supraclavicular nerve block in awake patients as an objective method.
With the use of ultrasound guidance in skilled hands, it is a reasonable option to perform neuraxial and peripheral regional blocks in sedated or anesthetized patients. However, there has been no evidence of applying PI for predicting the success of nerve block in general anesthetized patients.
