Local anesthetic infiltration may reduce postthyroidectomy pain. We performed a double-blinded, randomized, placebo-controlled trial to assess the analgesic efficacy of bilateral superficial cervical plexus blocks performed at the end of surgery. Ninety patients undergoing elective thyroid surgery by the same surgeon under general anesthesia were randomized to receive 20 mL isotonic sodium chloride or 20 mL bupivacaine 0.25% with 1:200,000 epinephrine. Postoperative pain was assessed every 4 h using an 11-point numeric rating scale (NRS-11). All patients received acetaminophen every 6 h. In addition, morphine was administered following a standardized protocol if the NRS-11 score was > or = 4. The main outcome variables were pain scores (NRS-11), the proportion of patients given morphine at any time during the 24-h period, and the amount of morphine administered. The Bupivacaine group had a smaller proportion of patients given morphine (66.0% vs 90.0%; P = 0.016), and lower initial median pain scores (P = 0.002). We conclude that bilateral superficial cervical plexus blocks significantly reduce pain intensity in the postoperative period after thyroid surgery but do not provide optimal pain relief alone.

Unilateral neck exploration (UNE) is a controversial approach to the treatment of primary hyperparathyroidism (PHP), and most surgeons favor bilateral neck exploration. The aim of this study was to assess the value of ultrasonography, sestamibi scintigraphy, and intraoperative measurement of urinary cyclic AMP (UcAMP) or 1-84 PTH in 200 patients undergoing unilateral neck exploration under local anesthesia. Conditions for UNE were (1) a presumed solitary adenoma detected by ultrasonography, (2) no thyroid disease, and (3) no family history of PHP or multiple endocrine neoplasia. Patient's consent was obtained for conversion to bilateral exploration according to surgical and biologic findings. Sensitivity of ultrasonography was 92.5%. Sestamibi scintigraphy, performed in 70 patients, was less sensitive than ultrasonography (80%). Persistent PHP was accurately detected by intraoperative measurement of UcAMP or 1-84 PTH in all cases. At follow-up, 96.0% of the patients were cured either after unilateral neck exploration only (90.5%), or after conversion into bilateral exploration. Ultrasonography and intraoperative measurement of 1-84 PTH allow unilateral neck exploration with excellent results in a selected group of patients with PHP.

The thoracoscopic approach for mediastinal parathyroidectomy is feasible and safe. An accurate preoperative work-up should be standardized to avoid useless procedures. In case of negative preoperative localization of the abnormal gland, thoracoscopy should not be adopted as a diagnostic tool.

We diagnosed transient left ventricular apical wall motion abnormalities after surgery in a patient presenting with a clinical and electrocardiographic picture of acute myocardial infarction in the absence of significant coronary disease. These angiographic, clinical, and electrocardiographic features satisfied the criteria of the recently described tako-tsubo-like left ventricular dysfunction.
