A 60-year-old female weighing 38 kg had complaints of bone pain, weight loss, easy fatigability, and recurrent history of flank pain. She was a diagnosed case of hypertension, with a history of resting tremors, chronic obstructive pulmonary disease, and hyperthyroidism and was recently diagnosed to have Parkinsonism More Details. She was on amlodipine, levodopa, carbidopa, trihexyphenidyl, bisphosphonates, propylthiouracil, inhaled corticosteroids, and levosalbutamol. Her investigations revealed parathormone levels 296.90 pg/ml, serum calcium 11.6 mg/dl, ionized calcium 1.62 mmol/l, phosphorus 2.3 mg/dl, Vitamin D3 7.2 ng/ml, and thyroid-stimulating hormone 0.3 μIU/ml. Ultrasound neck revealed multiple nodules in the bilateral thyroid lobes and a well-defined hypoechoic lesion in the inferior pole of left thyroid lobe. This case was taken up as a semiemergency and planned to be carried out under superficial and intermediate cervical plexus block using bupivacaine 0.5%. To allay anxiety, 1 mg midazolam was given, and as a part of preanesthetic medication, dexmedetomidine 0.7 μg/kg intravenous (iv) bolus was given, followed by infusion at a rate of 0.4 μg/kg/h. Bupivacaine 0.5% was injected bilaterally at two points approached by going just posterior and medial to the clavicular head of sternocleidomastoid muscle at a level midway between the mastoid process and clavicle. The first point injection was given after a pop was felt by penetrating cervical fascia (intermediate cervical plexus block) and the second point being superficially just medial and posterior to belly of sternocleidomastoid (superficial cervical plexus block) [Figure 1]. The patient was maintained on O2 by nasal prongs, dexmedetomidine infusion, and intermittent boluses of propofol 20 mg iv and fentanyl 25 μg iv. Intraoperative frozen section biopsy of the tissue revealed parathyroid with areas of calcification and parathormone (PTH) levels after removal of parathyroid was within normal limits. On follow-up, the patient was comfortable and pain-free, with a normal voice.

Parathyroid adenomas are associated with decreased bone density, so careful patient positioning is important to prevent fractures. Severe hypercalcemia can occur on rare occasions and should be managed using iv bisphosphonates, calcitonin, and steroids. Uncontrolled hypertension was one of the major concerns in this case, which was managed by the use of dexmedetomidine and fentanyl to diminish sympathetic response and labetalol to maintain blood pressure near baseline. In patients of parathyroid adenoma presenting with hypertension, abdominal scan is done to rule out pheochromocytoma associated with MEN2a. Adequate preparations were made to manage the precipitation of thyroid storm, which could have occurred on account of hyperthyroidism. Patients with Parkinson's disease can have pharyngeal muscle dysfunction, respiratory impairment due to rigidity and uncoordinated muscle movement, arrhythmias, muscle rigidity tremors, and confusion. Higher fentanyl doses and morphine can cause muscle rigidity; succinylcholine can possibly cause hyperkalemia; neuromuscular blocking drugs can mask tremors., All this was avoided by using cervical plexus block. In the postoperative period, special attention was paid to any possible voice change owing to recurrent laryngeal nerve injury., Cervical plexus block is an effective modality for anesthesia in surgeries on thyroid and parathyroid glands in patients suffering from multiple comorbidities.
We would like to acknowledge Dr. S. P. Agarwal, Plastic Surgeon (and his team), for excellent surgical skills, meticulous approach, and dedication toward patient's care.
