Objective To investigate the mental status of medical staffs in the orthopedics department during the earthquake, providing evidence for psychological intervention. Methods Choosing 104 staffs in the orthopedics department as eligible subject with convenient sampling; the research tool was Symptom Checklist-90. The questionnaire was done by the participants with the same instruction from psychological professionals; analyze the results. Results The score in somatization, anxiety and phobic anxiety of staffs in the orthopedics department was significantly higher than the national norm. Conclusion There exists disorder in mental health of medical staffs in orthopedics department, it is necessary to implement mental intervention.
Objective To evaluate the safety and efficacy of intermittent pneumatic compression in prevention of deep venous thrombosis after major orthopedic operation. Methods We searched MEDLINE (1966 to January 2008), The Cochrane Library (Issue 2, 2008), CBM (1996 to January 2008), CNKI (1998 to January 2008), VIP (1998 to January 2008), and retrieved clinical controlled trials (CCTs) or randomized controlled trials (RCTs) in which IPC was used as an intervention to prevent DVT, and all the trials were published in English or Chinese. The methodological quality of the included studies was assessed according to the standard of Cochrane systematic review. RevMan 4.2 software was used for meta-analysis. Results Seven RCTs and 1 CCT were included. Their methodological quality was poor. The results of Meta–analyses showed: (1) The incidence of DVT in the IPC group was lower than that in the control group (RR=0.20, 95%CI 0.11 to 0.35, Plt;0.000 01); (2) There was no difference in the incidence of DVT between the IPC group and the LMWH group (RR=0.70, 95%CI 0.28 to 1.74, P=0.44); (3) The incidence of DVT in the IPC plus LMWH group was lower than that in the LMWH-alone group (RR=0.23, 95%CI 0.10 to 0.52, P=0.000 4). Furthermore, the incidence of DVT in the IPC plus LMWH group was lower than that in the GCS plus LMWH group (Plt;0.000 1). No severe adverse reaction of IPC in DVT prevention was reported. Conclusion IPC shows an effective tendency in DVT prevention, but because of the low quality and the small sample of the included studies, this conclusion needs to be verified by protocols of more samples and high quality.
【摘要】 目的 探討口服百草枯中毒患者口腔護理的方法及早期護理的臨床意義。 方法 2009年1月-2010年3月，采用半隨機方法將62例白草枯中毒患者按中毒時間的長短分A組（中毒時間lt;3 d，n=32）、B組（中毒時間gt;3 d，n=3），比較兩組患者口腔潰瘍的治愈率、并發癥發生狀況，分析早期口腔護理的必要性。 結果 A組患者百草枯所致的口腔黏膜損害明顯減輕，并發癥發生率降低，為改善預后提供了條件，顯示了早期加強口腔護理的成效。 結論 重視百草枯早期口腔護理，能夠減輕口腔糜爛潰瘍痛苦，減少并發癥，提高患者生活質量。【Abstract】 Objective To investigate the clinical significance of early oral care for paraquat-poisoned patients. Methods A quasi-randomized controlled trial was used. A total of 62 paraquat-poisoned patients (from January 2009 to March 2010) were divided into experimental group and control group in order to compare the healing rate of oral ulcer, complications and the necessity of early oral care between the two groups. Results The oral mucosa lesions in experimental group obviously alleviated and the complications decreased. The effective early oral care provided the very favorable conditions for better prognosis. Conclusion The early oral care for paraquat-poisoned patients could relieve the pain of oral ulcer, reduce the complications and improve patient′s life quality.
Objective To observe the efficacy of hydrogel dressings in preventing and treating vein injury of rabbits so as to provide a experimental evidence for cl inical appl ication. Methods Twenty-four healthy large-eared Japanese rabbits (48 ears) were choosen, weighing (2.15 ± 0.15) kg, and divided into 3 groups randomly. The vein injury models were made byintravenously infusing 20% mannite (2.5 mL/kg). The sites of puncture were treated with hydrogel dressings (group A, n=8) and 25%MgSO4 (group B, n=8) 5 minutes after infusion. The sites of puncture were not treated as a blank control (group C, n=8). The tissue specimens were collected from the auricular veins at 24 hours after mannite infusion for histological observation by HE staining. The injury of the vessel wall, hemorrhage around the vessels, infiltration of inflammatory cells, and disturbance of circulation were observed to evaluate the injury degree of vein. Results There existed redness and congestion in the injured veins of each group. HE staining showed that in both groups A and B, the vessel wall was sl ightly injured and hemorrhage around the vessel was mild. There existed infiltration of inflammatory cells in the vessel wall and surrounding tissues. There also existed congestion and thrombus in the vessel lumen in these two groups. While in group C, the injury of vessel wall was severe, and schistic bleeding in the surrounding tissue of the vessel was existed. The severe congestion and thrombus in the vessel lumen was observed. There was no significant difference among three groups in the extent of vein wall injury and hemorrhage around the vessel (P gt; 0.05). The degree of infiltration of inflammatory cells and circulatory disturbance in both groups A and B were significantly less than that of group C (P lt; 0.05); but there was no significant difference between groups A and B (P gt; 0.05). Conclusion Hydrogel dressing is helpful to prevent vein injury of rabbits induced by mannite.
Nursing is one of the disciplines that has been influenced and inspired by the evidence-based medical thinking model during early times. In the past 20 years, evidence-based nursing has developed rapidly and vigorously in the field of international nursing and has become an inevitable trend of future nursing practice. Evidence-based nursing education, research and practice have been simultaneously promoted, and construction of the platform has gradually improved, forming a systematic evidence-based nursing science system and enriching the connotation of evidence-based science.
