Randomized Controlled Trial
Comparison of the effect of different volumes ropivacaine on deep serratus anterior plane block in patients undergoing breast surgery: a prospective randomized double-blinded trial.
A larger volume of local anesthetic provides a wider range of blocked sensory but carries a greater risk. The purpose of this trial was to compare the effect of different volumes of ropivacaine injected to deep serratus anterior plane in patients undergoing breast surgery. ⋯ The blocked dermatomes increased with increasing volume when 10, 20 and 30 mL ropivacaine was used for deep serratus anterior plane block. The analgesic effects of 20 and 30 mL were similar to each other and better than 10 mL. Therefore, in breast surgery, volume of 20 mL ropivacaine is considered to be appropriate for deep serratus anterior plane block.

Efficacy and safety of ultrasound-guided above-knee lateral approach for popliteal sciatic nerve block in surgeries below the knee: a randomized controlled trial.
Ultrasound guidance has become a standard method for detection of nerve structures in regional anesthesia. During ultrasound-guided blockade, to identify anatomical structures is crucial but can be challenging. In clinical practice, we find a wide difference in the visibility score of the sciatic nerve (SN) through different approaches. This study aimed to compare SNB through the anterior and above-knee lateral approach in terms of identification ease, performance efficacy, and safety. ⋯ Based on the visibility score, the above-knee lateral approach allowed easy SN identification and safe SNB. Using the ultrasound-guided above-knee lateral approach for SNB in below-knee surgeries could be a reliable choice.

Remifentanil injected during analepsia shortens length of postanesthesia care unit stay in patients undergoing laparoscopic surgery for endometrial cancer: a randomized controlled trial.
To guarantee efficient operating room (OR) activity, tracheal extubation is often performed in the postanesthesia care unit (PACU). Therefore, the ability of PACU to accommodate postoperative patients is crucial. Optimizing extubation management may speed up the turnover of PACU beds. The aim of the present study was to investigate the effect of remifentanil, which is used during analepsia, on the length of PACU stay in patients undergoing laparoscopic surgery for endometrial cancer. ⋯ Remifentanil, which is injected during analepsia, significantly shortens the duration of PACU stay without increasing adverse events in the peri-extubation period.

Effects of different positive end-expiratory pressure titrating strategies on oxygenation and respiratory mechanics during one- lung ventilation: a randomized controlled trial.
Positive end-expiratory pressure (PEEP) is widely used to reduce the risk of hypoxemia and atelectasis during one-lung ventilation (OLV); however, the optimal strategy for PEEP titrating remains unclear.The purpose of the study was to investigate the effects of different PEEP titrating strategies on oxygenation and respiratory mechanics during OLV. ⋯ The PEEP titrating strategy according to dynamic compliance can improve respiratory mechanics, whereas it has no significant effects on oxygenation, dead space ratio, and intrapulmonary shunt, suggesting that it is better during OLV for thoracic surgery.

Randomized Controlled Trial
A randomized trial of the dural puncture epidural technique combined with programmed intermittent epidural boluses for labor analgesia.
Continuous epidural infusion (CEI) can provide analgesia during labor. The dural puncture epidural (DPE) technique is used to accelerate the onset of neuraxia anesthesia. The primary objective of this study was to compare the percentage of patients that received adequate labor analgesia following an injection of 0.08% epidural ropivacaine via the DPE and CEI techniques combined with the PIEB mode of maintenance. ⋯ The percentage of parturients with adequate analgesia at 10 minutes was higher with DPE + PIEB compared to CEI + PIEB. Furthermore, the DPE + PIEB mode was associated with a faster time to a VAS score ≤30 mm.
