1Acupuncture accelerates recovery after general anesthesia: a prospective randomized controlled trial显示文摘BACKGROUND: Acupuncture anesthesia was created in the 1950's in China and continues to be used there today during most major surgeries. It is widely used in China for such complex operations as brain, heart, and abdominal surgery. It is popular in China because it is economical, practical, and beneficial to the patients. With acupuncture anesthesia there is less bleeding during surgery and there is also quicker post-operative recovery.OBJECTIVE: This randomized prospective study aims at comparing the effect of two acupoints(Yongquan, KI1 and Renzhong, DU26) with sham acupuncture and no acupuncture on the time to recovery of consciousness after general anesthesia by means of the Bispectral Index monitor(BIS).DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a prospective randomized controlled study. We randomly assigned 50 patients to 5 groups during recovery from surgical anesthesia. Four groups had acupuncture on KI1(group A), DU26(groups B), both KI1 and DU26(group C), and sham points(group D), and one had no acupuncture(group E).MAIN OUTCOME MEASURES: Bispectral Index(BIS), time to spontaneous eye opening, time to tracheal extubation, and time to following commands were measured as the main outcome measures.RESULTS: Time to spontaneous eye opening differed among groups(P=0.002), as well as time to tracheal extubation(P<0.000 1) and time to following commands(P=0.000 6). BIS values differed significantly among groups both 5 and 10 min after the end of anesthesia(P<0.000 1 and P=0.000 4,respectively). BIS values of groups D and E were lower than those of the other groups and those of group C were higher. The same pattern was observed also 15 and 30 min after the end of anesthesia, although the difference among groups was not significant at these time points(P=0.164 and P=0.104, respectively).CONCLUSION: Acupuncture on DU26 and KI1 accelerates recovery of consciousness after general anesthesia. Moreover, a possible synergistic effect of DU26 and KI1 is suggested. This issue may play a role in the optimization of operating room management and raise interest about the usefulness of acupuncture on unconsciousness states of different nature.Marco Gemma Elisa Nicelli Luigi Gioia Elena Moizo Luigi Beretta Maria Rosa Calvi 2015Journal of Integrative Medicine2015,13,2:13
2Timely reperfusion for ST-segment elevation myocardial infarction:Effect of direct transfer to primary angioplasty on time delays and clinical outcomes显示文摘Primary percutaneous coronary intervention(PPCI) is the preferred reperfusion therapy for patients presenting with ST-segment elevation myocardial infarction(STEMI) when it can be performed expeditiously and by experienced operators. In spite of excellent clinical results this technique is associated with longer delays than thrombolysis and this fact may nullify the benefit of selecting this therapeutic option. Several strategies have been proposed to decrease the temporal delays to deliver PPCI. Among them,prehospital diagnosis and direct transfer to the cath lab,by-passing the emergency department of hospitals,has emerged as anattractive way of diminishing delays. The purpose of this review is to address the effect of direct transfer on time delays and clinical events of patients with STEMI treated by PPCI.Rodrigo Estévez-Loureiro ángela López-Sainz Armo Pérez de Prado Carlos Cuellas Ramón Calvio Santos Norberto Alonso-Orcajo Jorge Salgado Fernández Jose Manuel Vázquez-Rodríguez Maria López-Benito Felipe Fernández-Vázquez 2014World Journal of Cardiology2014,6,6:6
3Simplified seismic performance assessment and implications for seismic design显示文摘The last decade or so has seen the development of refined performance-based earthquake engineering(PBEE) approaches that now provide a framework for estimation of a range of important decision variables,such as repair costs,repair time and number of casualties. This paper reviews current tools for PBEE,including the PACT software,and examines the possibility of extending the innovative displacement-based assessment approach as a simplified structural analysis option for performance assessment. Details of the displacement-based s+eismic assessment method are reviewed and a simple means of quickly assessing multiple hazard levels is proposed. Furthermore,proposals for a simple definition of collapse fragility and relations between equivalent single-degree-of-freedom characteristics and multi-degree-of-freedom story drift and floor acceleration demands are discussed,highlighting needs for future research. To illustrate the potential of the methodology,performance measures obtained from the simplified method are compared with those computed using the results of incremental dynamic analyses within the PEER performance-based earthquake engineering framework,applied to a benchmark building. The comparison illustrates that the simplified method could be a very effective conceptual seismic design tool. The advantages and disadvantages of the simplified approach are discussed and potential implications of advanced seismic performance assessments for conceptual seismic design are highlighted through examination of different case study scenarios including different structural configurations.Timothy J.Sullivan David P.Welch Gian Michele Calvi 2014Earthquake Engineering and Engineering Vibration2014,13,S1:3
