Abstract :

Summary

Objective: Describe the practice of axillary blockade with ultrasound guidance for surgery to create an arteriovenous fistula of the upper limb in the Anesthesia Department of Morafeno Toamasina Teaching Hospital.

Material and methods: A prospective descriptive study was carried out over a 12–month period at Morafeno Toamasina Teaching Hospital. It deals with patients who have undergone surgery for the creation of an arteriovenous fistula under axillary ultrasound guidance. Sociodemographic characteristics, preoperative anxiety, duration of the block, the time of installation of the sensory block, the incidents, the success rate, the duration of the sensory block, the comfort of the patient and the complications related to the technique were evaluated.

Results: We collected 74 cases, all classified ASA III, whose mean age was 46.7 ± 18.6 years divided into 52 men and 22 women. The mean duration of axillary block development was 8.4 ± 4.8 minutes. Complications and adverse events were 24.3% (n = 18). The average time to install the sensory block was 15.4 ± 6.2 minutes. The mean sensory block duration was 300.4 ± 120.8 minutes. The success rate of the axillary ultrasound–guided block was 89.2%. The patients were in a very comfortable state in 46 cases (62.2%).

Conclusion: These results have shown the interest of axillary blocking ultrasound for the surgery of creation of arteriovenous fistula of the upper limb with a high success rate and a not insignificant comfort.
