Scientific publications in anesthesiology journals from East Asia: a 10-year survey of the literature.
The scientific publications in anesthesiology research from East Asian authors have not been reported yet. The present study was designed to analyze the contribution of articles from East Asia to anesthesiology research. Articles published in 17 journals in anesthesiology originating from Japan, China, and South Korea from 2000 to 2009 were retrieved from the PubMed database and Web of Science. ⋯ Our analysis showed that Japan was the most productive region in East Asia, but there was a notable decrease in publications from Japan in 2000-2009. The impact factor of the articles suggests similar levels of scholarship. Anesthesia & Analgesia was the most popular journal in East Asia.

Randomized Controlled TrialOral melatonin, dexmedetomidine, and midazolam for prevention of postoperative agitation in children.
Several studies have reported that sevoflurane was associated with a relatively high incidence of emergence agitation in children even in the absence of any surgical intervention. The aim of this study was to compare early agitation characteristics of oral melatonin, dexmedetomidine, and midazolam premedication in children who were given sevoflurane anesthesia for esophageal dilatation. ⋯ We found that oral melatonin, dexmedetomidine, and midazolam reduced the incidence of emergence agitation in children after sevoflurane anesthesia.

Comparative StudyAccuracy of arterial pressure waveform analysis for cardiac output measurement in comparison with thermodilution methods in patients undergoing living donor liver transplantation.
The aim of this study was to assess the accuracy of the first and third versions of arterial pressure waveform cardiac output (APCO(v.1.0) and APCO(v.3.0)) measurements in comparison with thermodilution methods in patients undergoing living donor liver transplantation. ⋯ These data suggest that the accuracy of APCO(v.3.0) has improved compared to APCO(v.1.0) due to the updated algorithm, but additional improvements should be evaluated, especially in patients undergoing living donor liver transplantation with low systemic vascular resistance.

Comparative StudyPreoxygenation with 20º head-up tilt provides longer duration of non-hypoxic apnea than conventional preoxygenation in non-obese healthy adults.
Failed airway is the anesthesiologist's nightmare. Although conventional preoxygenation can provide time, atelectasis occurs in the dependent areas of the lungs immediately after anesthetic induction. Therefore, alternatives such as positive end-expiratory pressure (PEEP) and head-up tilt during preoxygenation have been explored. We compared the conventional preoxygenation technique (group C) with 20º head-up tilt (group H) and 5 cmH(2)O PEEP (group P) in non-obese individuals for non-hypoxic apnea duration. ⋯ Preoxygenation is clinically and statistically more efficacious and by inference more efficient in the 20º head-up position than with conventional technique in non-obese healthy adults. Although application of 5 cmH(2)O PEEP provides longer duration of non-hypoxic apnea compared to conventional technique, it is not statistically significant.

Randomized Controlled Trial Comparative StudyA randomized comparison of different doses of intrathecal levobupivacaine combined with fentanyl for elective cesarean section: prospective, double-blinded study.
Levobupivacaine may produce a sensory and motor block different from that produced by bupivacaine, which is the most popular local anesthetic in parturients undergoing cesarean section. The aim of this study was to investigate the block characteristics, the clinical efficacy, surgeon and patient satisfaction, and hemodynamic effects of using different doses of intrathecal plain levobupivacaine combined with fentanyl. ⋯ The incidence of hypotension was higher in the levobupivacaine 10 mg group, even though this group presented more effective anesthesia and greater patient and surgeon satisfaction compared with the levobupivacaine 5 and 7.5 mg groups. As a result, we believe that levobupivacaine 7.5 mg combined with fentanyl 15 μg is suitable for combined spinal-epidural anesthesia in elective cesarean section.
