title: [Thyroidectomy in the ambulatory setting. A prospective study].
abstract: BACKGROUND
  The recent reintroduction of local/regional anesthesia (LRA) for thyroidectomy has enabled this intervention to be performed in the outpatient setting. The aim of this study was to compare the results of thyroidectomy using two anesthesia methods.
  
  
  METHODS
  One hundred twenty-five patients requiring thyroidectomy and who met the criteria for outpatient surgery were prospectively selected. The patients were offered LRA plus sedation; patients who did not accept this option were offered LRA combined with orotracheal intubation (CLRA). LRA was accepted by 58 patients and CLRA by 67. Age, sex, anesthesia risk, body mass index, and thyroid function were similar in both groups. Postoperative vomiting, pain at discharge, need for admission, postoperative morbidity, and complaints occurring at home were evaluated.
  
  
  RESULTS
  Sixty-one bilateral and 64 unilateral thyroidectomies were performed, with no statistically significant difference between the two groups. There were no differences in surgical time, conversion to general anesthesia, intraoperative events, pathological diagnosis, or size and weight of the surgical specimen. The only difference between the two groups was the hour of discharge (LRA: 6.5 +/- 1.2 hours; CLRA: 7.76 +/- 2.07 hours; p = 0.0003). The admission rate was higher in the CLRA group (22.4%) than in the LRA group (8.62%); this difference was not statistically significant (p = 0.06) and the main cause was personal preference in patients in the CLRA group. Rates of postoperative morbidity, vomiting (7.2%) and nausea (6.4%), postoperative pain (2.47 +/- 1.85 on a visual analog scale), and analgesic requirements showed no differences between the two groups. One patient in the LRA group developed a noncompressive asymptomatic neck hematoma 36 hours after discharge. The patient was admitted for observation but did not require reoperation. Complaints occurring at home were minor. Satisfaction with the procedure was high or very high in 95% of the patients, with no differences between the two groups.
  
  
  CONCLUSIONS
  In selected patients, outpatient thyroidectomy is safe and produces good patient satisfaction. Both anesthesia methods were valid, but postoperative recovery was faster with LRA than with CLRA.
