Madam,

A 21-year-old male patient was posted for left femur osteosarcoma excision with free flap repair. He had undergone three chemotherapy cycles in the past. Surgery was done in supine position under general anesthesia. Epidural was not used as the patient was scheduled to receive fondaparinux during the surgery. His head was kept in midline on a head ring and both the arms were on arm boards at around 70°. Anesthesia time was 660 min and surgical time was 640 min. There were no episodes of hypotension or desaturation. Blood loss was 600 mL, and he received one packed red blood cell (PRBC) intraoperatively. He was extubated at the end of surgery without any complications and was shifted to the ward. The next morning, he complained of left upper limb weakness mainly at the shoulder and elbow joint. He had power 2/5 on left shoulder flexion, 0/5 on left shoulder extension, 2/5 on left shoulder adduction and abduction, 2/5 power on left elbow flexion, and 0/5 on left elbow extension. He complained of paresthesia along the left forearm. The power in the right upper limb, both lower limbs, and left wrist and fingers was 5/5. A neurologist's opinion was sought and a clinical diagnosis of brachial plexus injury (BPI) at C5–C6 level was made. Magnetic resonance imaging and electromyography (EMG)/nerve conduction velocity studies were deferred by 2–3 weeks according to the extent of recovery.

He was promptly started on intravenous methyprednisolone 500 mg for 3 days. Vitamin B12 was concurrently administered. Oral gabapentin 300 mg BD was started for pain and paresthesia. The arm was secured in a sling. He underwent regular physiotherapy of the affected arm and operated leg.

He started showing signs of recovery on day 4 with reduction in paresthesia and improvement in elbow flexion to 4/5. He kept improving and was discharged on day 7 with no paresthesia. Power was 2/5 on shoulder extension, 4/5 on shoulder flexion, 4/5 on shoulder adduction and abduction, 2/5 on elbow extension, and 4/5 on elbow flexion. The patient and his family were counseled about good rate of recovery and were advised to continue physiotherapy for 1 month. On 1-month follow-up, elbow flexion extension had completely recovered with power 5/5, shoulder power flexion was 4/5 and extension was 3/5, and power on shoulder adduction and abduction was 4/5. At 2 months' follow-up, there was full recovery of left shoulder and elbow.

The brachial plexus is anatomically prone to damage because it is fixed at the cervical vertebra, precervical fascia, and axillary fascia.[1] Causative factors for BPI during surgery are intraoperative positioning of the neck and arms, and comorbidities such as diabetes mellitus, anatomical malformations, prolonged operative times, median sternotomy, Trendelenberg position, obesity, hypotension, and hypothermia.[2] Suspicion of BPI in the postoperative period should arise when the patient complains of dysesthesia, heaviness, weakness, and altered sensation in the affected limb. Clinical examination detailing the sensory and motor loss should be meticulously done. Electrodiagnostic studies with nerve conduction and EMG will help in diagnosing BPI. Denervation changes in the nerves appear 2–3 weeks after the injury, and hence an EMG study done immediately after the injury may not reveal the correct picture.[3] Physiotherapy is the mainstay of treatment where the limb is put through full range of passive motion to keep the joints supple. A protective splint is provided to prevent damage to the flail limb.[4] Pharmacological agents used include gabapentin, steroids, and nonsteroidal analgesics. Vitamin B12 helps in rapid reinnervation of muscles and can be added.[5] In general, the prognosis of intraoperative BPI is fairly good, and patients feel symptomatic improvement within 10 weeks.[6]

Prevention of BPI primarily requires minimization of operating time in susceptible individuals and positions, hyperextension of the head, abduction, external rotation, and extension of the arm should be avoided.[1] Also, repetitive check on patient's intraoperative postures is necessary for prolonged surgeries. Recent studies have reported that utilization of cross chest straps, gel mattress, vacuum bags, and so on was helpful in staving off BPI for long-duration laparoscopy requiring the Trendelenburg position.[7] More recently, continuous monitoring of the somatosensory potentials in the ulnar nerve and transcranial electric motor-evoked potentials has shown that impending BPI can be detected earlier. This has been done more in relation to robotic thyroid surgery, but can be adopted in other cases as well.[8]

Despite considerable knowledge and preventive strategies, BPI remains a frequent occurrence in the perioperative setting. The importance of careful positioning is stressed; however, our patient despite being operated in supine position developed BPI. Mention of this complication in the preoperative discussion and consent forms will be helpful. A high index of suspicion and awareness of this complication among all involved personnel is needed so that preventive measures can be adopted along with constant monitoring of vulnerable patients.
