Abstract

Supraclavicular brachial plexus block is commonly used for upper extremity surgery. Respiratory arrest in three patients with end-stage renal disease after ultrasound-guided supraclavicular brachial plexus block for creation of an arteriovenous graft over a 6-month period is presented. Patients with renal failure may represent a group at particular risk for respiratory failure following supraclavicular brachial plexus block.

Introduction

Regional anesthesia for upper extremity surgery, including creation of arteriovenous (AV) grafts and fistulas, is increasingly more common. Decreased hospital length of stay, increased patient satisfaction, effective postoperative analgesia, reduced opioid requirements, and avoidance of airway instrumentation are just some of the reasons that regional anesthesia has gained popularity [1], [2], [3]. Regional anesthesia for AV graft formation has the additional benefit of improved graft patency [4].

Known complications of brachial plexus blocks include inadvertent subarachnoid or epidural injection, vertebral artery injection, recurrent laryngeal, cervical sympathetic, and vagus nerve blockade, pneumothorax, and phrenic nerve blockade manifesting as ipsilateral hemidiaphragmatic paresis [5], [6]. Hemidiaphragmatic paresis is a common complication of brachial plexus blocks, occurring 67% [7] of the time following a supraclavicular brachial plexus block, and up to 100% of the time following interscalene block [8]. Three cases of respiratory failure after supraclavicular brachial plexus block for AV graft placement at a single institution, over a 6-month period, are presented.

Case 1

A 48 year old man presented for right arm AV graft insertion for dialysis for end-stage renal disease (ESRD). His past medical history was significant for hypertension, congestive heart failure requiring an implantable cardioverter defibrillator, and morbid obesity, with a body mass index (BMI) of 40.3 kg/m2 and baseline shortness of breath. The patient received midazolam 1 mg for premedication and oxygen via nasal cannula. Initial oxygen saturation (SpO2) was 98%. Shortly following

Discussion

Three cases of respiratory distress following supraclavicular brachial plexus block in patients with ESRD undergoing AV graft formation are presented. These cases occurred over the course of 6 months, during which time we performed 67 brachial plexus blocks for AV graft formation, giving an incidence of 4.5%. During the same 6-month period, 421 supraclavicular brachial plexus blocks were placed for other procedures in patients without renal failure, primarily orthopedic, without respiratory

    However, in these studies [16,28] a much higher volume of local anesthetic was injected (30–50 ml and 33 ± 8 ml, respectively). A recent case series describes three patients who developed respiratory insufficiency requiring endotracheal intubation following an ultrasound-guided SCB for arterio-venous fistula surgery [39]. Chest X-ray showed no evidence of a pneumothorax.

    Inflammation including adhesions, fascial thickening, vascular changes, myotoxicity and the predisposing anatomy of the phrenic nerve may all play a role. Respiratory: In a single-centre institutional case series over a 6-month period a total of 67 supraclavicular blocks in patients with renal failure for arteriovenous graft formation were performed, and 3 cases of respiratory arrest occurred (4.5% incidence) [6C]. The authors conclude that ipsidiaphragmatic paresis, a known complication of supraclavicular block and its associated drop in forced vital capacity is poorly tolerated by some chronic renal failure patients and contributed to the respiratory arrests.
