Iwata AJ, et al. - Researchers evaluated the capacity of different techniques to lessen non-operative times during parathyroid surgery and analyzed 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 carried out 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). Results of this study 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.
