Case Reports Clinical Trial
Adjuvant Sufentanil Decreased the EC50 of Epidural Ropivacaine for Labor Analgesia in Healthy Term Pregnancy.
The optimal concentration of ropivacaine as epidural labor analgesia combined with sufentanil has not been established. This study aimed to determine the median effective concentration (EC50) of epidural ropivacaine for labor analgesia in healthy term pregnancy when co-administered with sufentanil as an adjuvant or alone. ⋯ The EC50 of ropivacaine was reduced by 22% when co-administered with sufentanil for epidural labor analgesia in primipara.

To compare the efficacy of a lower dose background infusion of oxycodone for patient-controlled intravenous analgesia (PCIA) with the conventional dose, following intercostal nerve block, for the management of postoperative pain in patients undergoing thoracoscopic lobectomy for lung cancer. ⋯ A low-dose background infusion of oxycodone for postoperative PCIA can achieve a comparable analgesic effect to the conventional dose after thoracoscopic lobectomy for lung cancer. Furthermore, the low-dose regimen was associated with reduced consumption of oxycodone and increased patient satisfaction.

Randomized Controlled Trial
The Safety and Efficacy of Ultrasound-Guided Bilateral Dual Transversus Abdominis Plane (BD-TAP) Block in ERAS Program of Laparoscopic Hepatectomy: A Prospective, Randomized, Controlled, Blinded, Clinical Study.
Postoperative pain management for patients undergoing hepatic resection is still a challenge due to the risk of perioperative liver dysfunction. The transversus abdominis plane (TAP) block is a promising regional analgesic technique. However, the correct guidelines regarding the dose and regimen of local anesthetics in patients undergoing hepatic resection have yet to be established completely. This study aimed to evaluate the safety and efficacy of ultrasound-guided BD-TAP block with a large dose of ropivacaine in laparoscopic hepatectomy. ⋯ Ultrasound-guided BD-TAP block provides effective postoperative analgesia after laparoscopic hepatectomy. This study also confirms that ultrasound-guided BD-TAP blocks with 3 mg/kg ropivacaine during laparoscopic hepatectomy almost never results in the plasma ropivacaine concentrations associated with neurotoxicity.

The novel coronavirus 2019 (2019-nCoV), formally named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a novel human infectious coronavirus. The disease caused by SARS-CoV-2 is named COVID-19. Development and manufacturing of specific therapeutics and vaccines to treat COVID-19 are time-consuming processes. ⋯ However, information related to COVID-19 is rapidly growing. Several clinical trials are ongoing for the management of COVID-19 using remdesivir. In this study, characteristics of remdesivir and its usage for treatment of COVID-19 are reviewed based on an electronic search using PubMed and Google Scholar.

This study aims to comprehensively evaluate the characteristics of clinical drug trials to facilitate the collection of evidence for COVID-19 drug treatments. ⋯ The designs of COVID-19 clinical drug trials have greatly improved in terms of the implementation of randomization and, particularly, blinding methods. In terms of drug reuse, the number of drug types has greatly increased, and hundreds of drugs have been used for efficacy screening. The emergence of large-sample registration trials is expected to address the uncertainty regarding the current clinical efficacy of some drugs.
