CORPUS CAVERNOSUM AS AN ALTERNATIVE MEANS OF INTRAVENOUS ACCESS IN THE EMERGENCY SETTING

ANZ JOURNAL OF SURGERY, Issue 7 2000
D. Nicol
Background: The present study was designed to investigate the feasibility of using the corpus cavernosum as an alternative means of intravenous access in the emergency setting. Methods: The feasibility of achieving the infusion flow rates was first ascertained using direct intracavernous infusion of normal saline. The effect of atropine and adrenaline when given via this route was then studied. Hypovolaemic shock was then induced in dogs who were then actively resuscitated via this route using normal saline, Haemaccel and whole blood. Results: Infusion flow rates were achieved for normal saline of 32.3, 50.3 and 67.3 mL per min at 100, 200 and 300 mmHg pressure, respectively. The peak effects of atropine and adrenaline via this route were seen at approximately 1 min after injection. Resuscitation using this method was uniformly successful in all dogs via the corpus cavernosum, with all reaching or exceeding their premorbid central venous pressure (CVP), and approaching or reaching their premorbid mean arterial pressure (MAP). In comparison the control dog's CVP and MAP did not rise during the period of observation after it was bled. Conclusions: The corpus cavernosum is a practical alternative means of intravenous access in the emergency setting in the dog model. [source]


Implementing Early Goal-directed Therapy in the Emergency Setting: The Challenges and Experiences of Translating Research Innovations into Clinical Reality in Academic and Community Settings

ACADEMIC EMERGENCY MEDICINE, Issue 11 2007
Alan E. Jones MD
Research knowledge translation into clinical practice pathways is a complex process that is often time-consuming and resource-intensive. Recent evidence suggests that the use of early goal-directed therapy (EGDT) in the emergency department care of patients with severe sepsis and septic shock results in a substantial mortality benefit; however, EGDT is a time- and resource-intensive intervention. The feasibility with which institutions may translate EGDT from a research protocol into routine clinical care, among settings with varying resources, staff, and training, is largely unknown. The authors report the individual experiences of EGDT protocol development, as well as preimplementation and postimplementation experiences, at three institutions with different emergency department, intensive care unit, and hospital organization schemes.

Using Design Effects From Previous Cluster Surveys to Guide Sample Size Calculation in Emergency Settings

DISASTERS, Issue 2 2006
Reinhard Kaiser
Abstract A good estimate of the design effect is critical for calculating the most efficient sample size for cluster surveys. We reviewed the design effects for seven nutrition and health outcomes from nine population-based cluster surveys conducted in emergency settings. Most of the design effects for outcomes in children, and one-half of the design effects for crude mortality, were below two. A reassessment of mortality data from Kosovo and Badghis, Afghanistan revealed that, given the same number of clusters, changing sample size had a relatively small impact on the precision of the estimate of mortality. We concluded that, in most surveys, assuming a design effect of 1.5 for acute malnutrition in children and two or less for crude mortality would produce a more efficient sample size. In addition, enhancing the sample size in cluster surveys without increasing the number of clusters may not result in substantial improvements in precision. [source]


Another patient with an umbilical hernia and massive ascites: What to do?

LIVER TRANSPLANTATION, Issue 1 2008
James D. Perkins M.D. Special Editor
Background Optimal management in patients with umbilical hernias and liver cirrhosis with ascites is still under debate. The objective of this study was to compare the outcome in our series of operative versus conservative treatment of these patients. Methods In the period between 1990 and 2004, 34 patients with an umbilical hernia combined with liver cirrhosis and ascites were identified from our hospital database. In 17 patients, treatment consisted of elective hernia repair, and 13 were managed conservatively. Four patients underwent hernia repair during liver transplantation. Results Elective hernia repair was successful without complications and recurrence in 12 out of 17 patients. Complications occurred in 3 of these 17 patients, consisting of wound-related problems and recurrence in 4 out 17. Success rate of the initial conservative management was only 23%; hospital admittance for incarcerations occurred in 10 of 13 patients, of which 6 required hernia repair in an emergency setting. Two patients of the initially conservative managed group died from complications of the umbilical hernia. In the 4 patients that underwent hernia correction during liver transplantation, no complications occurred and 1 patient had a recurrence. Conclusions Conservative management of umbilical hernias in patients with liver cirrhosis and ascites leads to a high rate of incarcerations with subsequent hernia repair in an emergency setting, whereas elective repair can be performed with less morbidity and is therefore advocated.

Predicting postoperative morbidity by clinical assessment

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 1 2005
P. M. Markus
Background: The aim of this study was to determine the accuracy of prediction of the surgeon's ,gut-feeling' in estimating postoperative outcome. Methods: A prospective series of 1077 consecutive patients undergoing major hepatobiliary or gastrointestinal surgery were studied. Patients having elective (n = 827) and emergency (n = 250) procedures were included. The surgeon predicted the development of postoperative complications immediately after completion of surgery on a scale from 0 to 100 per cent. These predictions were compared with the actual outcome and with predictions made using the Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM). The Portsmouth predictor equation (P-POSSUM) was applied for the estimation of mortality. Results: The observed morbidity and mortality rates were 29·5 and 3·4 per cent respectively. POSSUM predicted a morbidity rate of 46·4 per cent and P-POSSUM a mortality rate of 6·9 per cent. The surgeon's gut-feeling was more accurate in the prediction of morbidity at 32·1 per cent. On the basis of gut-feeling, surgeons overpredicted morbidity in elective surgery, but underestimated the risk of complications in the emergency setting. The (P)-POSSUM scoring system overpredicted morbidity and mortality for elective and emergency operations. Conclusion: The surgeon's gut-feeling is a good predictor of postoperative outcome, especially after elective surgery. (P)-POSSUM overpredicted morbidity and mortality in this series of major gastrointestinal and hepatobiliary operations. Copyright © 2005 British Journal of Surgery Society Ltd.

Using the ,protective environment' framework to analyse children's protection needs in Darfur

DISASTERS, Issue 4 2009
Alastair Ager
A major humanitarian concern during the continuing crisis in Darfur, Sudan, has been the protection of children, although there has been little in the way of comprehensive analysis to guide intervention. Founded on a situational analysis conducted between October 2005 and March 2006, this paper documents the significant threats to children's well-being directly linked to the political conflict. It demonstrates the role of non-conflict factors in exacerbating these dangers and in promoting additional protection violations, and it uses the ,protective environment' framework (UNICEF Sudan, 2006a) to identify systematic features of the current environment that put children at risk. This framework is shown to provide a coherent basis for assessment and planning, prompting broad, multidisciplinary analysis, concentrating on preventive and protective action, and fostering a systemic approach (rather than placing an undue focus on the discrete needs of ,vulnerable groups'). Constraints on its present utility in emergency settings are also noted. [source]

Competence profiles of recently registered nurses working in intensive and emergency settings

JOURNAL OF NURSING MANAGEMENT, Issue 8 2007
ANNE H. SALONEN MNSc
Background, Preceptorship is an essential method of supporting nurse competence, guaranteeing high quality care and increasing job satisfaction. Aim, To describe recently registered nurses' perceptions of their competence level, and to identify factors influencing these perceptions. Method, The survey was conducted by using Meretoja's Nurse Competence Scale. The sample comprised 235 registered nurses working in intensive and emergency settings. The data were analysed by using statistical methods. Results, Nurses' self-assessed competence level ranged from moderate to good. A statistically significant association was seen between competence level and age, length of current work experience and the frequency of using competencies. Conclusions, The results shed useful light on the educational needs of nurses and provide important clues for the development of preceptorship programmes. The Nurse Competence Scale proved to be a reliable and valid instrument in assessing the competence of recently registered nurses. Implications for nursing management, We recommend that management strategies be developed to enhance and support positive learning environments for competence development. We recommend preceptorship programmes based on systematic competence assessments made by nurses themselves, their preceptors and managers. [source]


Use of a think-aloud procedure to explore the relationship between clinical reasoning and solution-focused training in self-harm for emergency nurses

JOURNAL OF PSYCHIATRIC & MENTAL HEALTH NURSING, Issue 2 2009
M. MCALLISTER rn edd
Self-harm is a risk factor for further episodes of self-harm and suicide. The most common service used by self-injurers is the emergency department. However, very often, nurses have received no special training to identify and address the needs of these patients. In addition this care context is typically biomedical and without psychosocial skills, nurses can tend to feel unprepared and lacking in confidence, particularly on the issue of self-harm. In a study that aimed to improve understanding and teach solution-focused skills to emergency nurses so that they may be more helpful with patients who self-harm, several outcome measures were considered, including knowledge, professional identity and clinical reasoning. The think-aloud procedure was used as a way of exploring and improving the solution-focused nature of nurses' clinical reasoning in a range of self-harm scenarios. A total of 28 emergency nurses completed the activity. Data were audiotaped, transcribed and analysed. The results indicated that significant improvements were noted in nurses' ability to consider the patients' psychosocial needs following the intervention. Thus this study has shown that interactive education not only improves attitude and confidence but enlarges nurses' reasoning skills to include psychosocial needs. This is likely to improve the quality of care provided to patients with mental health problems who present to emergency settings, reducing stigma for patients and providing the important first steps to enduring change , acknowledgment and respect.
