“…Several volume reduction studies have shown the highly effective application of ultrasound for ulnar [18], sciatic [19] and ilioinguinal-iliohypogastric blocks [20] in adults and children. In addition, Ó Donnell et al and Marhofer et al [21,22] have described low volume blockade of the axillary part of the brachial plexus. Co-incidental blockage of the great auricular nerve can occur if large volumes of local anaesthetic are injected but that cannot have been the case in this study.…”

SummaryThis prospective, observational volunteer study aimed to describe the appearance of the great auricular nerve using ultrasound and its blockade under ultrasound guidance. An in‐plane needle guidance technique was used for blockade of the great auricular nerve with 0.1 ml mepivacaine 1%. Sensory block was evaluated by pinprick testing in comparison with the contralateral area propriae. The great auricular nerve was successfully seen in all volunteers and the tail of the helix, antitragus, lobula and mandibular angle were blocked in all cases whereas the antihelix and concha were never blocked. Ultrasound imaging of the great auricular nerve can be reliably achieved and successful blockade with minimal volumes of local anaesthetic is another example of the benefits of ultrasound‐guided peripheral nerve blocks.

“…Ponrouch [12] also indicated a positive correlation between the administered volume of the anaesthetic and the time of duration for the median nerve and the ulnar nerve block. Marhofer [14] noticed the trend towards prolongation of analgesia time after administration with a higher volume of local anaesthetic agent. This finding is not unambiguous, regardless of whether this effect may be caused by an increase in volume or the dose of local anaesthetic agent.…”

Axillary brachial plexus block is one of the most frequently employed peripheral blocks. The popularity of axillary block stems from its success as a safe and relatively easy technique with numerous applications. The technique of axillary block has evolved. It was modified after the development of precise nerve localization modalities. Currently, ultrasound is the most important localization technique for regional anaesthesia. Ultrasound-guided axillary block encompasses a spectrum of techniques. The selection of a specific technique can be adjusted to an operator's individual level of skill and proficiency. Axillary block under US-guidance can be performed using a traditional perivascular method and by placing a selective blockade of individual nerves that supply the surgical area. Regardless of the selected method, it enables the incorporation of individual patient anatomical variation in an anaesthesia plan. This paper discusses the technical details and efficacy issues of US-guided axillary brachial plexus block techniques.Keywords: regional anaesthesia, peripheral nerve block, brachial plexus; regional anaesthesia, peripheral nerve block, axillary block; regional anaesthesia, techniques Anaesthesiology Intensive Therapy 2015, vol. 47, no 4, 417-424 Axillary brachial plexus block is one of the most frequently employed peripheral blocks. The popularity of axillary block derives from its success as a very safe and relatively easy technique with numerous applications. The technique of axillary block has evolved. It was modified after the development of precise nerve localization modalities. Currently, ultrasonography is the most important localization technique for regional anaesthesia. Ultrasound-guided axillary block encompasses a spectrum of techniques. The selection of a specific technique can be adjusted to an operator's individual skills and proficiency. Ultrasound-guided axillary block can be performed using a traditional perivascular method and by placing a selective blockade of individual brachial plexus branches that supply the field of surgical operation. Regardless of the selected method, it enables the incorporation of individual anatomical variability into the anaesthesia plan of a patient. TECHNIQUE OF ULTRASOUND-GUIDED AXILLARY BRACHIAL PLEXUS BLOCKThe use of ultrasonography enables all steps of a regional block to be controlled, such as determination of the anatomical structure of the anaesthetized region via realtime control, operational correction of the needle position and verification of the injection site and pathway of local anaesthetic agent dispersion [2]. Ultrasonography enables the assignment of an optimal site of needle puncture and the planning of the insertion vector based on the topographic relationships among particular patients.The utilization of this technique has introduced new possibilities of axillary block performance and has significantly changed its operation compared with traditional methods. Assuming that a crucial factor of effective/failed block is the appr...

“…With the ultrasound to guide peripheral nerve block, the total volume of local anesthetic can be dramatically reduced so as to limit the risk of toxic side effects due to the drug. [3][4][5][6] The aim of this study is to determine the effectiveness of these two techniques, so that a more effective technique can be used for anesthesia superior extremity orthopedic surgery or can be used as an alternative option, and the authors believe that the particular regional anesthesia regional anesthesia is to minimize the inflammatory process that occurs as a result of actions surgery.…”

Background:Regional anesthesia has an anti-inflammatory effect that blockade the C-fiber hence reduced cytokine production and blocked the activity of the sympathetic nerve fibers. Postoperative pain caused primarily by tissue inflammation and activity of the C-fibers in the manner of reduced the production of cytokines, regional anesthesia may limit the inflammatory response after surgery and severity of postoperative pain. Methods: This study is a clinical experimental study with randomized pre and post test control group design. A total of 24 samples were recruited in this study divided into two groups each consisting of 12 samples. The first group was given regional anesthesia method of continuous brachial plexus block with ultrasound guidance and the second group with general anesthesia method. T-test or Mann-Whitney continued multivariate linear regression analysis was performed to analyze the differences in treatment and not because of differences in the initial values with significance level of p<0.05. Results: This study reports that the mean decreased levels of IL-6 postoperatively in 1 st group is 29.8 lower than in 2 nd group and it is statistically significant p< 0.05. There was an increase of IL-10 mean levels from preoperative to postoperatively with significance level of p<0.05 in both groups. Declined in the mean levels of PAF postoperatively in 1 st group 1.3 lower than 2 nd group and it was statistically significant p<0.05. The declined of postoperative VAS in 1 st group is 3.1 lower than 2 nd group and it is statistically significant p< 0.05, and it also contained the pure effect of PAF levels against value of VAS that any increased 1ng/ml levels of PAF then an increase in the value of 0.18 cm VAS and this was statistically significant p<0.05. Selection of this anesthesia technique in orthopedic antebrachii surgery provides better inflammatory response and improved clinical outcomes.
