PCT showed comparable efficacy and safety to PMT with respect to respiratory complications, hypotension and arrhythmia, recovery time, procedure duration, patient satisfaction, and doctor satisfaction. However, the average dose of propofol used was higher in PMT.

Background: This study was purposed to compare in vitro the volumetric accuracy of a newly introduced automatic infusion controller, AutoClamp with that of other commonly used infusion devices. Methods: Four different volumetric infusion devices were used to examine the accuracy: Terufusion TE-112; Volumed μVP7000; AutoClamp; and Infucon. Accuracy was determined for each flow rate (20, 40, 100, and 200 ml/h) by using infusate volumes collected after 3 h of initiating the fluid administration. Accuracy was calculated as the percentage difference between set volume and actual volume delivered. The influences of fluid viscosity and flow resistance on infusion device accuracy were also evaluated. Results: There were no cases of a greater-than-10% difference between set volume and actual delivered volume. The accuracy of the Infucon was significantly less than that of the other devices. Infusion devices proved to be consistent and unaffected by fluid viscosity or flow resistance except for the Infucon. Conclusion: The accuracy of the AutoClamp was comparable to that of other commonly used infusion pumps (Terufusion TE-112 and Volumed μVP7000) regardless of infusate viscosity and flow resistance.This is an open access article licensed under the terms of the (https://creativecommons.org/licenses/by/4.0/legalcode), which permits unrestricted, noncommercial use, distribution and reproduction in any medium, provided the work is properly cited.

In this study, we aimed to compare the effect of desflurane and sevoflurane on postoperative nausea and vomiting and pain in patients receiving opioid-based intravenous patient-controlled analgesia (IV-PCA) after thyroidectomy.We reviewed the electronic medical records of 1042 patients administered opioid-based IV-PCA after a thyroidectomy at Chung-Ang University Hospital between January 1, 2010 and June 30, 2016. We classified the patients into 2 groups according to the inhalation anesthetic used for anesthesia: desflurane versus sevoflurane (groups D and S, n = 587 and 455, respectively). Then, propensity scoring was used to select 234 matched subjects between both groups based on their confounding factors. A propensity score matching method was used to match patients from the 2 groups in a 1:1 ratio.Before the propensity score analysis, there was no significant difference between the 2 groups. However, after the propensity score matching, the frequency of complete remission (CR, defined as no nausea and vomiting) was significantly higher in group S than it was in group D. The number of patients administered rescue antiemetics on day 0 in group S was lower than that in group D, although it was not statistically significant.In patients receiving opioid-based IV-PCA after thyroidectomy, sevoflurane seems to be more beneficial in achieving CR than desflurane was. However, further randomized controlled studies are needed to confirm this conclusion.
