Background. The role and significance of the technical aspects of interscalene brachial plexus block in the occurrence of sudden arterial hypotension and bradycardia events during shoulder arthroscopy in a semi-sitting position are ambiguous. Aim. The study aimed to assess the effect of interscalene brachial plexus block on the incidence of hypotension-bradycardia events during shoulder arthroscopic surgery in adolescents in a semi-sitting position. Materials and methods. This retrospective analysis of anesthesia protocols included 288 patients who underwent arthroscopic shoulder surgery in a semi-sitting position under the interscalene brachial plexus block. Regional blockades were performed with neurostimulation in Group 1 (n = 23), neurostimulation and ultrasound navigation without repositioning the needle in Group 2 (n = 70), and neurostimulation and ultrasound navigation with multiple precision repositioning the needle in Group 3 (n = 195). Results. Hypotension-bradycardia events were detected in 26 patients out of 288 (9%). There was a statistically significant difference in the frequency of hypotension-bradycardia in all groups: 10 (43.48%) in Group 1, 15 (21.43%) in Group 2, and 1 (0.51%) in Group 3 (p = 0.000). A direct correlation between hypotension-bradycardia episodes and local anesthetic volume (r = 0.405; p 0.05), and Horners syndrome (r = 0.684, p 0.05) was found. Conclusions. Interscalene brachial plexus block with a target delivery of low volume of local anesthetic and dual navigation reduces the risk of hypotension-bradycardia. Horners syndrome can be considered an early predictor of hypotension-bradycardia events.

System Toxicity

Local anesthetics are commonly administered by nuchal infiltration to provide a temporary interscalene brachial plexus block (ISB) in a surgical setting. Although less commonly reported, local anesthetics can induce central nervous system toxicity. In this case study, we present three patients with acute central nervous system toxicity induced by local anesthetics applied during ISB with emphasis on neurological symptoms, key neuroradiological findings and functional outcome. Medical history, clinical and imaging findings, and outcome of three patients with local anesthetic-induced toxic left hemisphere syndrome during left ISB were analyzed. All patients were admitted to our neurological intensive care unit between November 2016 and September 2019. All three patients presented in poor clinical condition with impaired consciousness and left hemisphere syndrome. Electroencephalography revealed slow wave activity in the affected hemisphere of all patients. Seizure activity with progression to status epilepticus was observed in one patient. In two out of three patients, cortical FLAIR hyperintensities and restricted diffusion in the territory of the left internal carotid artery were observed in magnetic resonance imaging. Assessment of neurological severity scores revealed spontaneous partial reversibility of neurological symptoms. Local anesthetic-induced CNS toxicity during ISB can lead to severe neurological impairment and anatomically variable cerebral lesions.

This study evaluated the effects of adding adjuvant clonidine to lidocaine with epinephrine on the characteristics of ultrasound-guided axillary brachial plexus block (ABPB) for upper extremity surgery. Twenty-four patients were randomised to receive an ultrasound guided ABPB with 20 mL of lidocaine 2% with 1:200,000 epinephrine plus 2 mL of either normal saline 0.9% (Group 1) or a mixture of clonidine 1 µg/kg and normal saline 0.9% (Group 2). The outcome measures that were recorded were the overall onset time and the duration of sensory and motor block. The median (IQR) overall onset time of sensory and motor block was significantly shorter in Group 2 vs. Group 1 (5 (5–7.5) min vs. 10 (8.8–12.5) min; p < 0.001) and (5 (2.5–7.5) min vs. 7.5 (6.3–7.5) min; p = 0.001), respectively. The median (IQR) overall duration of sensory and motor block was significantly longer in Group 2 vs. Group 1 (225 (200–231) min vs. 168 (148–190) min; p < 0.001) and (225 (208–231) min vs. 168(148–186) min; p < 0.001), respectively. In ultrasound-guided ABPB, the addition of clonidine to lidocaine with epinephrine resulted in shorter onset time and prolonged duration of sensory and motor block.

Objective: To evaluate the effectiveness of interscalene brachial plexus block versus combined suprascapular and axillary nerves block for shoulder arthroscopy. Methods: In this prospective study 174 patients were operated on the shoulder joint by the arthroscopic method under combined anesthesia. In the 1st group (n=96), for the purpose of analgesia, patients got interscalene brachial plexus block; in the 2nd group (n=78), patients received suprascapular and axillary nerves block. Ultrasound visualization and neurostimulation were used in both groups. Recorded the time from the start of blockade to the start of the operation, as well as the duration of the sensory and motor blockade. The intensity of postoperative pain was assessed with a 10-point Numeric rating scale, the need for additional analgesia, the quality of night sleep, and patient comfort. Neurological complications were also recorded. Results: There were no differences in the time from the admit patients to the operating room and before the start surgery. The analgesic effect in the early postoperative period in the 1st group was higher, but by the end of the first day there was no statistical difference between the groups in the intensity of the pain syndrome. Intake of non-narcotic and narcotic analgesics was higher in the 2nd group. Complications were noted only for the 1st group: diaphragm paresis in 6 (6.25%) patients, in 2 (2.08%) recurrent laryngeal nerve blockade. Satisfaction with postoperative analgesia was 100% in patients of the 2nd group. The choice of regional anesthesia for arthroscopic interventions on the shoulder did not affect the length of hospitalization. Conclusion: Selective anesthesia of the suprascapular and axillary nerves during shoulder arthroscopic surgery is an alternative of interscalene brachial plexus block; it is not associated by respiratory and neurological complications; does not violate movements in the distal upper limb, reduces psychological discomfort and anxiety of patients.

Aims: Ultrasound guidance has led to marked improvement in the success rate and characteristics of peripheral nerve blocks. However, effects of varying the volume or concentration of a fixed local anaesthetic dose on nerve block remains unclear. The purpose of our study was to evaluate whether at a fixed dose of lidocaine, altering the volume and concentration will have any effect on the onset time of ultrasound-guided axillary brachial plexus block.Material and methods: Twenty patients were randomised to receive an ultrasound-guided axillary brachial plexus block with either lidocaine 2% with epinephrine (20 ml, Group 2%) or lidocaine 1% with epinephrine (40 ml, Group 1%). The primary endpoint was block onset time. Secondary outcomes included duration of the block, performance time, number of needle passes, incidence of paraesthesia and vascular puncture.Results: The median [IQR] onset time of surgical anaesthesia was shorter in Group 1% when compared to Group 2% (6.25 [5-7.5] min vs 8.75 [7.5-10] min; p=0.03). The mean (SD) overall duration of surgical anaesthesia was significantly shorter in Group 1% compared to Group 2% (150.9±17.2 min vs 165.1±5.9 min; p=0.02). Group 1% had a shorter performance time with fewer needle passes. The incidence of vascular puncture and paraesthesia was similar in the two groups.Conclusion: Ultrasound-guided axillary brachial plexus blocks performed using a higher volume of lower concentration lidocaine was associated with shorter onset time and duration of surgical anaesthesia.
