Abstract
BackgroundBrachial plexus block is useful for upper extremity surgery, and many techniques are available. The aim of our study was to compare the efficacy of axillary brachial plexus block using an ultrasound technique to the peripheral nerve stimulation technique.Methods60 patients scheduled for surgery of the forearm or hand were randomly allocated into two groups (n = 30 per group). For Group 1; US, and for Group 2 PNS was applied. The quality and the onset of the sensorial and motor blockade were assessed. The sensorial blockade, motor blockade time and quality of blockade were compared among the cases.ResultsThe time needed to perform the axillary brachial plexus block averaged is similar in both groups (p > 0.05). Although not significant statistically, it was observed that the sensory block had formed earlier in Group 1 (p > 0.05). But the degree of motor blockade was intenser in Group 1 than in Group 2 (p < 0.05).ConclusionsUltrasound offers a new possibility for identifiying the nerves of the brachial plexus for regional anesthesia. The ultrasound-guided axillary brachial plexus block is a safe method with faster onset time and better quality of motor blockade compared to peripheral nerve stimulation technique.
Highlights
Regional anaesthesia can be defined as removing nerve conduction and pain at the certain parts of a body without causing sensory loss [1]
A method of regional anaesthesia used for this purpose is brachial plexus block that is applied in operations to be carried out on the 1/3 distal part of upper extremities as well as hands, forearms and arms
We have aimed to compare the sensory and motor block effects of peripheral nerve stimulation (PNS), that facilitates the application of axillary brachial plexus block (AXB) and increases the prospects, and the technique of ultrasonography (US) that has recently been put into use
Summary
Regional anaesthesia can be defined as removing nerve conduction and pain at the certain parts of a body without causing sensory loss [1]. A method of regional anaesthesia used for this purpose is brachial plexus block that is applied in operations to be carried out on the 1/3 distal part of upper extremities as well as hands, forearms and arms. Axillary block techniques can be applied by using transarterial fixation, In our study, we have aimed to compare the sensory and motor block effects of peripheral nerve stimulation (PNS), that facilitates the application of axillary brachial plexus block (AXB) and increases the prospects, and the technique of ultrasonography (US) that has recently been put into use.
