Randomized Controlled TrialDetermination of the Optimal Volume of Programmed Intermittent Epidural Bolus When Combined With the Dural Puncture Epidural Technique for Labor Analgesia: A Random-Allocation Graded Dose-Response Study.
The dural puncture epidural (DPE) and the programmed intermittent epidural bolus (PIEB) techniques are recent innovations for labor analgesia. The optimal volume of PIEB during traditional epidural analgesia has been investigated previously but it is unknown whether these findings are applicable to DPE. This study aimed to determine the optimal volume of PIEB for effective labor analgesia after initiation of analgesia using DPE. ⋯ Under the conditions of the study, after initiation of analgesia using DPE, the EV90 of PIEB for effective labor analgesia using ropivacaine 0.1% with sufentanil 0.5 μg/mL was approximately 11.3 mL.

Randomized Controlled TrialPreoperative Ultrasound-Guided Internal Branch Block of Superior Laryngeal Nerve Reduces Postoperative Sore Throat Caused by Double Lumen Endotracheal Intubation: A Randomized Trial.
Postoperative sore throat (POST) is one of the more common side effects of tracheal intubation patients under general anesthesia (GA) after extubation using double-lumen endobronchial tubes (DLTs). The internal branches of the superior laryngeal nerve (SLN) block (iSLNB) have been reported to anesthetize the larynx for airway manipulation (such as awake tracheal intubation) and pain treatment efficiently. We hypothesized that ultrasound-guided iSLNB (US-guided iSLNB) combined with GA would ameliorate the incidence and severity of POST and hoarseness. ⋯ Preoperative US-guided iSLNB could significantly ameliorate the incidence and severity of POST induced by double-lumen bronchial catheter intubation.
