山羊高原重度原发性肺冲击伤模型的建立

目的建立山羊在海拔4 600 m高原环境下的重度原发性肺冲击伤模型,分析高原重度原发性肺冲击伤的特点,为院前救治提供实验基础。 方法选取健康山羊28只,随机分为3 m组22只,3.5 m组6只,采用8 kg TNT当量新型爆炸物,在相同的环境条件下致伤,观察致伤后山羊肺冲击伤伤情,分别于伤前、伤后1 h、24 h监测山羊生命体征、肌钙蛋白Ⅰ,观察肺大体解剖,测肺组织重量、湿/干比重(W/D)等,对重伤山羊进行院前ABC救治。 结果伤后t≤15 min死亡12只,伤后15 min相似文献   

对新护士进行积极心理健康知识培训的效果研究

目的：探讨对新护士进行积极心理健康(PMH)知识培训的效果。方法选择本院2014年7~9月新入职的26名护士,对其进行PMH知识培训,于培训前后采用幸福进取者问卷(HEIQ)和护生职业认同调查问卷(NSPIQ)评价培训效果。结果培训前,新护士HEIQ、NSPIQ评分的总分为(3.48±0.41)、(101.43±12.85)分,培训后分别为(4.21±0.58)、(127.05±15.16)分,培训前后比较,差异有统计学意义(t=5.24、6.57,P<0.01)。结论对新护士进行PMH知识培训能够提高其职业认同感。

Pathogen-Reservoir Interactions: What We Do Not Know Likely Will Hurt Us

The establishment of selective colonies of potential vertebrate hosts for viruses would provide experimental models for the understanding of pathogen-host interactions. This paper briefly surveys the reasons to conduct such studies and how the results might provide information that could be applied to disease prevention activities.     

Barriers to implementing expert safety recommendations for early mobilisation in intensive care unit during mechanical ventilation: A prospective observational study

BackgroundEarly mobilisation in the intensive care unit (ICU) has been consistently reported as feasible and safe with minimal adverse events; however, invasive mechanical ventilation patients are rarely actively mobilised. An expert consensus group developed and published recommendations using a traffic light system on safety criteria to promote active mobilisation of invasive mechanical ventilation patients.ObjectivesThe aim of this study was to determine whether, in clinical practice, the safety consensus recommendations resulted in (1) increased early mobilisation in patients assessed as appropriate to mobilise based on the risk classification and (2) early mobilisation without adverse events.MethodsA prospective observational study of 100 patients requiring invasive mechanical ventilation (IMV) for greater than 24 h admitted to the ICU at The Alfred Hospital. Patients were assessed daily (Monday to Friday) to determine their ability to perform early mobilisation.ResultsData were collected on 100 patients, resulting in 280 physiotherapy–patient interactions during IMV. Of the 100 patients, five patients actively mobilised out of bed during IMV. No adverse event occurred during active physiotherapy–patient interactions. There were 15 physiotherapy–patient interactions that had a low risk of an adverse event, and on nine (60.0%) of these physiotherapy–patient interactions, patients were actively mobilised out of bed with the main reported barrier being time constraints. Of 208 physiotherapy–patient interactions where there were significant potential risks of an adverse event identified for mobilising, active out of bed mobilisation did not occur, with sedation being reported as the main barrier in 170 (82%) patients.ConclusionsThe translation of expert consensus recommendations for early mobilisation into clinical practice was poor. Clinicians were safe and conservative in the implementation of early mobilisation during IMV.     

An investigation of the effectiveness against bacteriuria of silver-coated catheters in short-term urinary catheter applications: A randomized controlled study

AimThe aim of this study was to investigate the effectiveness of antimicrobial-coated catheters against bacteriuria and urinary tract infection in patients who have urinary catheterization.MethodsTwenty eight and twenty six people similar in terms of demographic characteristics and primary and underlying diseases were randomly selected from patients undergoing short-time urinary catheterization in the intensive care unit. Silver-coated slicone foley catheters and normal slicone foley catheters were used for uninary catheterization in the first and second group of the patients respectively. Urine specimens were collected from patients at 2-day intervals and assessed in terms of bacteriuria.ResultsBacteriuria was found in 12 (46.2%) of the patients using normal catheters and 13 (46.4%) of those using silver-coated catheters throughout the monitoring period. No significant relationship was determined between use of different catheter types and bacteriuria (p = 0.98). The most common microorganism was identified as E. coli in the normal catheter group while microorganism other than E. coli was identified in the silver-coated catheter group. The prevalence of bacteriuria was statistically significantly higher in patients with a history of hospitalization in the previous 3 months (p = 0.028).ConclusionThe use of silver-coated silicone catheters was not shown to have a protective effect against bacteriuria in this study. Further well-designed studies with larger case numbers are now needed to confirm whether history of hospitalization, which emerged as a statistically significant factor in this study, increases the prevalence of catheter-related bacteriuria.
