Research progress in application of different types of hemostatic materials in trauma first aid / 中华创伤杂志

Hemostatic materials are essential for the treatment of trauma patients with massive blood loss in battlefields and disaster environments. According to the site and severity of trauma, different types of hemostatic materials need to be used to stop bleeding urgently. At present, first-aid hemostatic materials for bleeding on body surface wounds, extremities and junctions have been well applied. However, in the case of deep bleeding wounds in the thoracic and abdominal cavity and internal organs and even non-compressible hemostasis, there are still no ideal hemostatic materials in early emergency treatment. In this review, the authors elaborate the classification and mechanism of hemostatic materials and their application in trauma first aid, so as to provide references for the use of hemostatic materials in first aid.

Effect of Shanghai's standardized training of residents on the history taking mode of physicians / 中华医学教育探索杂志

Objective To evaluate the needs of performing a standardized communication skill training program for residents according to the differences in history taking mode of residents with different degrees and before and after the standardized training in Shanghai Changhai Hospital in 2010.Methods History taking modes of 81 residents in 2010 before and after the standardized training in Shanghai Changhai hospital were categorized.History taking modes were classified into:no effectiveness mode,traditional mode,disease-sickness mode and Calgary-Cambridge Guide mode.Distribution differences of history taking mode of residents with different medical degrees were analyzed by Fisher exact probability method (α =0.05).Distribution differences of history taking mode of residents before and after standardized training were analyzed by Pearson x2 test (α =0.05).Results 19.8％ residents took no effectiveness mode,53.0％ took traditional mode and 27.2％ used disease-sickness mode.There were significant differences in history taking modes among residents with different medical degrees (P =0.008).After training,history taking modes of residents were significantly changed (P=0.001),only 1.2％ residents used no effectiveness mode,59.3％ used traditional mode and 34.6％ used disease-sickness mode.But residents using the Calgary-Cambridge mode were not increased.Conclusions There are significant differences in history taking modes among residents with different medical degrees.History taking mode of residents changed after standardized training.But some of the residents still use non-optimal history taking modes; therefore a standardized communication skill training program might be needed in the future.
