| 1 | Management of polytrauma patients in emergency department:An experience of a tertiary care health institution of northern India显示文摘BACKGROUND:In a tertiary care institute of northern India,the emergency department receives an average of 6-7 patients with poly trauma every day.Of these patients,some come directly and many are referred from other hospitals from the region.Various problems are faced in the management of patients with poly trauma.This study aimed to elicit various complaints,suggestions and possible solutions in the management of patients with poly trauma.METHODS:A retrospective cross sectional study was done on 210 patients in the emergency OPD for a period of 2 months.All the records of the patients with poly trauma were studied and the problems during their management were measured against 6 predetermined steps(step Ⅰ to step Ⅵ).RESULTS:In the younger generation,males were predominantly the primary victims of poly trauma injury,and road traffic accident was the major etiological factor.Injuries involving more than2 specialties induced many problems during the management of patients with poly trauma.Of 210 patients we studied,32 patients had problems at various steps and maximum problems in step Ⅲ,i.e.co-ordination between various specialties in the management of patients with poly trauma.CONCLUSION:A proper poly trauma management team and a well defined standard operative procedure are the keys to effective management of patients with poly trauma by minimizing the problems encountered. | Puri Payal Goel Sonu Gupta Anil K Verma Prachi | 2013 | World Journal of Emergency Medicine2013，4，1： | 2 |
| 2 | Lumped parameter analytic modeling and behavioral simulation of a 3-DOF MEMS gyro-accelerometer显示文摘A new analytical model of a 3-degree-of-freedom(3-DOF) gyro-accelerometer system consisting of a 1-DOF drive and 2-DOF sense modes is presented. The model constructs lumped differential equations associated with each DOF of the system by vector analysis. The coupled differential equations thus established are solved analytically for their responses in both the time and frequency domains. Considering these frequency response equations, novel device design concepts are derived by forcing the sense phase to zero, which leads to a certain relationship between the structural frequencies, thereby causing minimization of the damping effect on the performance of the system. Furthermore, the feasibility of the present gyro-accelerometer structure is studied using a unique discriminatory scheme for the detection of both gyro action and linear acceleration at their events. This scheme combines the formulated settled transient solution of the gyro-accelerometer with the processes of synchronous demodulation and filtration, which leads to the in-phase and quadrature components of the system's output signal. These two components can be utilized in the detection of angular motion and linear acceleration. The obtained analytical results are validated by simulation in a MATLAB/Simulink environment, and it is found that the results are in excellent agreement with each other. | Payal Verma Sandeep K.Arya Ram Gopal | 2015 | Acta Mechanica Sinica2015，31，6： | 1 |
