Iwata AJ, et al. - In this investigation, researchers evaluated the capacity of different techniques to lessen non-operative times during parathyroid surgery and studied the impact of monitored anesthesia care (MAC) instead of general anesthesia and the preoperative placement of a second peripheral intravenous catheter (PIV). Between November 2013 and October 2016, a retrospective case series at an academic medical center was conducted to study patients undergoing parathyroidectomy by a single surgeon. Three operating room (OR) time measurements have been compared: preincision time, postclosure time, and total OR time. Compared with those in which general anesthesia (n = 169) was used, surgeries performed under MAC (n = 21) had statistically shorter preincision (33.2 min vs 39.7 min), postclosure (10.1 min vs 16.2 min), and total operative times (113.0 min vs 151.5 min). Findings suggested that placing a second PIV in the preoperative holding area and performance of surgery under MAC can significantly shorten non-operative and total OR time in patients undergoing parathyroid surgery in which ioPTH levels will be used.
