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.

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.

ReviewAnesthetic management of noncardiac surgery for patients with single ventricle physiology.
Patients with congenital heart diseases are a growing population, and noncardiac surgeries will become an important health care issue. Patients with single ventricle physiology are a particularly challenging population who will undergo staged, palliative repair toward a final step of Fontan circulation. Although Fontan surgery creates a serial circulation in which the ventricle pumps blood to the systemic circuit, pulmonary blood flow occurs without a dedicated ventricle. ⋯ Health care professionals must prepare for these patients to present to noncardiac surgery at any stage of intervention, possibly with complications. Given that staged, palliative repair has undergone multiple modifications, patients who present for surgery can vary in types and timing of the repair. Anesthesiologists who care for them must be familiar with perioperative issues to optimize outcomes, especially because congenital heart disease is a risk factor for increased mortality for noncardiac surgery.

Comparative StudyUse of rocuronium-sugammadex, an alternative to succinylcholine, as a muscle relaxant during electroconvulsive therapy.
We compared the recovery time from neuromuscular blockade induced by rocuronium combined with sugammadex versus succinylcholine during electroconvulsive therapy (ECT). Anesthesia was induced using propofol, followed by succinylcholine (1 mg/kg) or rocuronium (0.6 mg/kg). Immediately after the seizure stopped, 16 mg/kg sugammadex was infused. ⋯ Although recovery time of T1 to 10 and 90% in the rocuronium-sugammadex group was shorter than in the succinylcholine group, the difference was not statistically significant. Further, the seizure duration with succinylcholine (33 ± 8 s) was shorter than that with rocuronium-sugammadex (39 ± 4 s). In conclusion, this study demonstrates the potential benefit of use of rocuronium-sugammadex as an alternative to succinylcholine for muscle relaxation during ECT.
