Randomized Controlled TrialComparison of three obturator nerve block techniques for injectate spread into the obturator canal: a randomized controlled trial.
The obturator nerve branches into the obturator canal; therefore, local anesthetic spread into the obturator canal predicts the success of the obturator nerve block (ONB). We compared three ONB techniques for the spread of local anesthetic mixed with contrast medium into the obturator canal. ⋯ Local anesthetic spread into the obturator canal using the UMA was superior to that using the PA and IA. Both branches of the obturator nerve could be blocked using the UMA.

Case ReportsVenoarterial extracorporeal membrane oxygenation for septic cardiomyopathy caused by Pasteurella multocida infection: a case report.
Pasteurella is a gram-negative coccobacillus that is commonly transmitted through cat and dog bites and causes various diseases in humans. In the present case, kissing an animal caused Pasteurella multocida infection, leading to sepsis and cardiogenic shock. We used venoarterial extracorporeal membrane oxygenation (VA-ECMO) to support the cardiovascular system until recovery. ⋯ He was discharged home and resumed his former life 50 days later. Pasteurella multocida infection can cause sepsis followed by severe cardiac dysfunction in healthy adults. Therefore, VA-ECMO may be a useful treatment option in patients with sepsis-induced myocardial dysfunction and refractory cardiogenic shock.

Review Meta AnalysisDural puncture epidural versus conventional epidural analgesia for labor: a systematic review and meta-analysis of randomized controlled studies.
Dural puncture epidural (DPE) technique is a modification of the conventional epidural (EP) technique in that the dura is intentionally punctured with a spinal needle but without any spinal injection. This meta-analysis aimed to evaluate the benefits and risks associated with the DPE technique for labor analgesia. Randomized trials comparing DPE analgesia with EP analgesia for labor pain relief were systematically searched in the database of Medline, Embase, Cochrane Controlled Trials Register, Web of Science, and China Biology Medicine till 1st August 2021. ⋯ No adverse event was found with DPE analgesia. We conclude that compared with EP analgesia, DPE analgesia is beneficial for labor pain relief by shortening the time to achieve satisfactory pain control. Meanwhile, DPE analgesia is not associated with increased adverse maternal/fetal events.

Effects of anesthetics on expression of dopamine and acetylcholine receptors in the rat brain in vivo.
Dopamine D2 and acetylcholine M1 receptors might be related to post-operative cognitive dysfunction. The aim of the present study is to investigate whether several anesthetics which are used for general anesthesia and/or sedation, affect expression of dopamine D2 and acetylcholine M1 receptors in the rat brain. Thirty-six male rats aged 5-9 weeks old were divided into six groups (n = 6 in each group); five groups for anesthetics and one for control. ⋯ Then, real-time polymerase chain reaction was performed to examine the expression of Drd2 (cord dopamine D2 receptor) and Chrm1 (cord acetylcholine M1 receptor). There were no significant differences among the groups regarding Drd2 and Chrm1 mRNA expression of each region of the brain. Postsynaptic changes of dopamine D2 and acetylcholine M1 receptors due to administration of dexmedetomidine, propofol, midazolam, sevoflurane, and nitrous oxide are unlikely to occur at the doses of each anesthetic used in the present study.

Multicenter Study Observational StudyThe frequency of postoperative BNP measurement and intervention threshold of BNP concentration in pediatric cardiac intensive care unit: a prospective multicenter observational study.
The purpose of this study is to investigate the current status of postoperative BNP measurement in the pediatric cardiac intensive care unit (PCICU). ⋯ High BNP concentration, especially more than 1000 pg/ml, was more often intervened upon compared to that of less than 1000 pg/ml.
