Multicenter Study Comparative Study Clinical TrialEvaluation of entropy for monitoring the depth of anesthesia compared with bispectral index: a multicenter clinical trial.
As a new electroencephalogram (EEG) signal processing technique for monitoring the depth of anesthesia, entropy consists of two indices: reaction entropy (RE) and state entropy (SE). Our study compared entropy with classical bispectral index (BIS) in reduction of myoelectrical interference and noxious stimuli with EEG signals. ⋯ This large-sample multicentric study confirmed the values of RE and SE as approximating BIS value, at the onset of unconsciousness during propofol TCI anesthesia. After elimination of myoelectrical activation, all values of RE, SE and BIS decreased significantly and the three indices were less sensitive to noxious stimuli than cardiovascular responses.

Impact of emergency percutaneous coronary intervention on outcomes of ST-segment elevation myocardial infarction patients complicated by out-of-hospital cardiac arrest.
Cardiac arrest is one of the most serious complications of acute myocardial infarction (AMI), especially in the out-of-hospital patients. There is no general consensus as to whether percutaneous coronary intervention (PCI) is effective in treating ST-segment elevation myocardial infarction (STEMI) patients complicated by out-of-hospital cardiac arrest (OHCA). In our study, we evaluated the efficacy of PCI in treating STEMI patients complicated by OHCA through observing their clinical conditions in hospital; including total mortality, adverse cardiac events, stroke, acute renal failure, and gastrointestinal bleeding events. ⋯ During hospitalization, the incidence of adverse events and mortality are higher in the STEMI with OHCA patients, comparing with the STEMI without OHCA. Emergency PCI reduces the incidence of adverse events and decreases mortality during hospitalization, which is effective for treating STEMI with OHCA patients.

Patients with pelvic fractures are often treated in hospitals without the capacity to implement an open reduction internal fixation (ORIF). This often leads to pelvic malunion in patients with unstable pelvic fracture, shock or even death due to uncontrollable pelvic hemorrhage and unstable hemodynamics. This study explored the role of early external fixation (within 7 days) for patients with unstable pelvic fractures. ⋯ The early application of external fixation in unstable pelvic fracture patients positively affects hemodynamic stability, with outstanding efficacy as a final fixation option for unstable pelvic fractures.

Impact of a nationwide training program for neonatal resuscitation in China.
Seventeen million births occur in China each year. Neonatal mortality is the leading cause of under 5-year-old child deaths, and intrapartum-related injury accounts for much of mental retardation in young children. The Chinese Ministry of Health sought to improve infant and child survival through a nationwide initiative to have at least one person trained in neonatal resuscitation at every birth. The aim of the current study was to evaluate the impact of China Neonatal Resuscitation Program (NRP) on policy and infrastructure changes and its effectiveness in decreasing the incidence of mortality among newborn infants. ⋯ The Chinese NRP achieved policy changes promoting resuscitation, trained large numbers of professionals, and contributed to reduction in delivery room mortality. Improved adherence to the resuscitation algorithm, extension of training to the township level, and coverage of births now occurring outside health facilities can further increase the number of lives saved.

Combined laparoscopic and thoracoscopic Ivor Lewis esophagectomy for esophageal cancer: initial experience from China.
Minimally invasive Ivor Lewis esophagectomy was usually performed with either hand-sewn or circular stapler anastomosis through a small thoracotomy or using a side-to-side stapler anastomotic technique. This study aimed to present our initial results of Ivor Lewis esophagectomy using a circular-stapled anastomosis with transoral anvil technique. ⋯ The initial results of this small series suggest that minimally invasive Ivor Lewis esophagectomy for malignant esophageal tumor is technically feasible. However, further multi-center prospective studies and thorough evaluation are needed to evaluate the long-term results.
