Randomized Controlled Trial
Analgesic effect of ultrasound-guided erector spinae plane block (espb) in general anesthesia for cesarean section: a randomized controlled trial.
The analgesic effects of erector spinae plane block in general anesthesia for cesarean section and recovery from puerperae remain unclear. ⋯ Ultrasound-guided ESPB applied to general anesthesia for a cesarean section can significantly reduce the required dose of general anesthetic drugs, shorten the recovery time of the puerperae, and improve postoperative analgesia.

Observational Study
Validation of the Dutch translation of the quality of recovery-15 scale.
The 15-item Quality of Recovery-15 (QoR-15) scale is strongly recommended as a standard patient-reported outcome measure assessing the quality of recovery after surgery and anesthesia in the postoperative period. This study aimed to validate the Dutch translation of the questionnaire (QoR-15NL). ⋯ The QoR-15NL scale is a valid, easy-to-use, and reliable outcome assessment tool with high responsiveness for patient-reported quality of recovery after surgery and general anesthesia in the Dutch-speaking population. The QoR-15NL's measurement properties are comparable to the original questionnaire and other translated versions.

Ultrasound-assisted modified paramedian technique for spinal anesthesia in elderly.
At present, there are two techniques which are widely applied clinically; the midline and the paramedian. Both methods are difficult for clinicians when treating the elderly. The aim of this work is to explore the feasibility of an ultrasound-assisted modified paramedian technique for spinal anesthesia in the elderly. This would provide clinicians with a new and easy-to-operate technique. ⋯ The modified paramedian technique in spinal anesthesia for elderly patients can significantly improve the first-attempt success rate, reduce both the number of attempts and procedure time, and minimize tissue damage during the operation. Compared with the traditional techniques, the modified paramedian technique combines the advantages of both the midline and the paramedian methods, and is easy to learn. It is worthy of further research and application.

Randomized Controlled Trial
Opioid-free anesthesia compared to opioid anesthesia for laparoscopic radical colectomy with pain threshold index monitoring: a randomized controlled study.
Few studies have investigated the depth of intraoperative analgesia with non-opioid anesthesia. This study evaluated whether opioid-free anesthesia can provide an effective analgesia-antinociception balance monitored by the / pain threshold index in laparoscopic radical colectomy. ⋯ This study suggests that compared to the opioid anesthesia regimen, our opioid-free anesthesia regimen achieved an equally effective intraoperative pain threshold index in laparoscopic radical colectomy. The incidence of opioid-related adverse reactions was not different between regimens, and intraoperative blood glucose levels were higher with opioid-free anesthesia.

Hypotension that is resistant to phenylephrine is a complication that occurs in anesthetized patients treated with angiotensin converting enzyme (ACE) inhibitors. We tested the hypothesis that Ang 1-7 and the endothelial Mas receptor contribute to vasodilation produced by propofol in the presence of captopril. ⋯ Mas receptor activation by Ang 1-7 contributes to phenylephrine-resistant vasodilation in resistance arterioles pretreated with captopril and exposed to propofol. These data suggest an alternative mechanism by which refractory hypotension may occur in anesthetized patients treated with ACE inhibitors.
