Randomized Controlled TrialAn Innovative Approach to Determine Programmed Intermittent Epidural Bolus Pump Settings for Labor Analgesia: A Randomized Controlled Trial.
Three settings are required on a programmed intermittent epidural bolus (PIEB) pump for labor analgesia: the PIEB next bolus (PIEBnb), PIEB interval (PIEBi), and PIEB volume (PIEBv). The ideal settings for these parameters are still unknown. We hypothesized a mathematical modeling tool, response surface methodology (RSM), could estimate 3 PIEB pump parameters while balancing 3 clinically important patient outcomes simultaneously. The study objective was to use RSM to estimate PIEB settings (PIEBnb, PIEBi, and PIEBv) while maximizing maternal satisfaction, minimizing the need for clinician-administered boluses, and optimizing the ratio of delivered/requested patient-controlled epidural analgesia (PCEA) boluses simultaneously. ⋯ This novel study used a mathematical model to estimate PIEB pump settings while simultaneously maximizing 3 clinical outcomes. Equally weighted clinical outcomes prevent maximal outcome optimization and may not reflect patient priorities. Future studies or quality improvement endeavors could use RSM methodology to estimate PIEB pump settings targeting optimal values for a single clinical outcome of determined importance to parturients.

Randomized Controlled Trial Comparative StudyEffect of Volatile Anesthesia Versus Intravenous Anesthesia on Postoperative Pulmonary Complications in Patients Undergoing Minimally Invasive Esophagectomy: A Randomized Clinical Trial.
The effect of intraoperative anesthetic regimen on pulmonary outcome after minimally invasive esophagectomy for esophageal cancer is yet undetermined. The aim of this study was to determine the effect of volatile anesthesia (sevoflurane or desflurane) compared with propofol-based intravenous anesthesia on pulmonary complications after minimally invasive esophagectomy. ⋯ In patients undergoing minimally invasive esophagectomy, the use of volatile anesthesia (sevoflurane or desflurane) resulted in the reduced risk and severity of pulmonary complications within the first 7 postoperative days as compared to propofol-based intravenous anesthesia.
