Management of blunt injuries to the spleen

Non-operative management (NOM) of blunt splenic injuries is nowadays considered the standard treatment. The present study identified selection criteria for primary operative management (OM) and planned NOM.

[Treatment practice in patients with isolated blunt splenic injuries : A survey of Swiss traumatologists.]

The non-operative management (NOM) of blunt splenic injuries has gained widespread acceptance. However, there are still many controversies regarding follow-up of these patients. The purpose of this study was to survey active members of the Swiss Society of General and Trauma Surgery (SGAUC) to determine their practices regarding the NOM of isolated splenic injuries.

Concomitant injuries are an important determinant of outcome of high-grade blunt hepatic trauma

BACKGROUND: Little is known about the clinical importance of concomitant injuries in polytraumatized patients with high-grade blunt liver injury. A retrospective single-centre study was performed to investigate the safety of non-operative management of liver injury and the impact of concomitant intra- and extra-abdominal injuries on clinical outcome. METHODS: Some 183 patients with blunt liver injury were admitted to Berne University Hospital, Switzerland, between January 2000 and December 2006. Grade 3-5 injuries were considered to be high grade. RESULTS: Immediate laparotomy was required by 35 patients (19.1 per cent), owing to extrahepatic intra-abdominal injury (splenic and vascular injuries, perforations) in 21 cases. The mortality rate was 16.9 per cent; 22 of the 31 deaths were due to concomitant lesions. Of 81 patients with high-grade liver injury, 63 (78 per cent) were managed without surgery; liver-related and extra-abdominal complication rates in these patients were 11 and 17 per cent respectively. Grades 4 and 5 liver injury were associated with hepatic-related and extra-abdominal complications. CONCLUSION: Concomitant injuries are a major determinant of outcome in patients with blunt hepatic injury and should be given high priority by trauma surgeons. An algorithm for the management of blunt liver injury is proposed.

Patientensicherheit in der Shuntchirurgie

Zusammenfassung Hintergrund. Hämodialysepatienten, die operativ mit einem Gefäßzugang versorgt werden müssen, sind eine vulnerable Patientengruppe, die aufgrund von Multimorbidität, der intensiven und oft fragmentierten Behandlung und vieler Schnittstellen ein erhöhtes Risiko für vermeidbare unerwünschte Ereignisse tragen. Fragestellung. Aktuelle Entwicklungen und Maßnahmen zur Förderung der Patientensicherheit mit Fokus auf die Shuntchirurgie. Material und Methoden. Auswertung und Aufarbeitung aktueller Daten zur Patientensicherheit und Instrumenten zu ihrer Förderung. Ergebnisse. Fehler im nicht operativen Management verursachen einen wesentlichen Anteil der unerwünschten Ereignisse. Checklisten, präoperative Seitenmarkierung, Zählkontrollen und interprofessionelle Teamtrainings sind wichtige Instrumente der Patientensicherheit im OP. Standardisierungen von postoperativen Übergaben durch einfache Protokolle können erheblich zur Reduktion von Fehlern und Schädigungen beitragen. Die Sicherheitskultur einer Abteilung ist ein Umgebungsfaktor, der für die Effektivität dieser Sicherheitsbarrieren wesentlich ist. Schlussfolgerungen. Es existieren wirksame Instrumente, die die Patientensicherheit in der Shuntchirurgie fördern. Gerade an den Schnittstellen zur weiteren Versorgung können durch die konsequente Implementierung und Nutzung dieser Maßnahmen und ein aktives Sicherheitsmanagement unerwünschte Ereignisse vermieden werden. Die interprofessionelle und interdisziplinäre Zusammenarbeit und der Einbezug der Patienten sind wichtige Ressource für die Behandlungssicherheit, die stärker genutzt werden sollten.

Ethnosciences - A step towards the integration of scientific and non-scientific forms of knowledge in the management of natural resources for the future

Integration of indigenous knowledge and ethnoscientific approaches into contemporary frameworks for conservation and sustainable management of natural resources will become increasingly important in policies on an international and national level. We set the scene on how this can be done by exploring the key conditions and dimensions of a dialogue between ‘ontologies’ and the roles, which ethnosciences could play in this process. First, the roles which ethnosciences in the context of sustainable development were analysed, placing emphasis on the implications arising when western sciences aspire to relate to indigenous forms of knowledge. Secondly, the contributions of ethnosciences to such an ‘inter-ontological dialogue’ were explored, based on an ethnoecological study of the encounter of sciences and indigenous knowledge in the Andes of Bolivia, and reviewed experiences from mangrove systems in Kenya, India and Sri Lanka, and from case-studies in other ecosystems world-wide.

The efficacy of non-pharmacological interventions in the management of procedural pain in preterm and term neonates. A systematic literature review

BACKGROUND: Neonates in a neonatal intensive care unit are exposed to a high number of painful procedures. Since repeated and sustained pain can have consequences for the neurological and behaviour-oriented development of the newborn, the greatest attention needs to be paid to systematic pain management in neonatology. Non-pharmacological treatment methods are being increasingly discussed with regard to pain prevention and relief either alone or in combination with pharmacological treatment. AIMS: To identify effective non-pharmacological interventions with regard to procedural pain in neonates. METHODS: A literature search was conducted via the MedLine, CINAHL, Cochrane Library databases and complemented by a handsearch. The literature search covered the period from 1984 to 2004. Data were extracted according to pre-defined criteria by two independent reviewers and methodological quality was assessed. RESULTS: 13 randomised controlled studies and two meta-analyses were taken into consideration with regard to the question of current nursing practice of non-pharmacological pain management methods. The selected interventions were "non-nutritive sucking", "music", "swaddling", "positioning", "olfactory and multisensorial stimulation", "kangaroo care" and "maternal touch". There is evidence that the methods of "non-nutritive sucking", "swaddling" and "facilitated tucking" do have a pain-alleviating effect on neonates. CONCLUSIONS: Some of the non-pharmacological interventions have an evident favourable effect on pulse rate, respiration and oxygen saturation, on the reduction of motor activity, and on the excitation states after invasive measures. However, unambiguous evidence of this still remains to be presented. Further research should emphasise the use of validated pain assessment instruments for the evaluation of the pain-alleviating effect of non-pharmacological interventions.

Psychoendocrine validation of a short measure for assessment of perceived stress management skills in different non-clinical populations

BACKGROUND: We investigated the psychometric properties of a short questionnaire for combined assessment of different perceived stress management skills in the general population and tested whether scores relate to physiological stress reactivity. METHODS: For psychometric evaluation, we determined the factor structure of the questionnaire and investigated its measurement invariance in the participant groups and over time in three different independent samples representing the general population (total N=332). Reliability was tested by estimating test-retest reliability, internal consistency, and item reliabilities. We examined convergent and criterion validity using selected criterion variables. For endocrine validation, 35 healthy non-smoking and medication-free men in a laboratory study and 35 male and female employees in a workplace study underwent an acute standardized psychosocial stress task. We assessed stress management skills and measured salivary cortisol before and several times up to 60 min (workplace study) and 120 min (laboratory study) after stress. Potential confounders were controlled. RESULTS: The factor structure of the questionnaire consists of five scales reflecting acceptably distinct stress management skills such as cognitive strategies, use of social support, relaxation strategies, anger regulation, and perception of bodily tension. This factor structure was stable across participant groups and over time. Internal consistencies, item reliabilities, and test-retest reliabilities met established statistical requirements. Convergent and criterion validity were also established. In both endocrine validation studies, higher stress management skills were independently associated with lower cortisol stress reactivity (p's<.029). CONCLUSIONS: Our findings suggest that the questionnaire has good psychometric properties and that it relates to subjective psychological and objective physiological stress indicators. Therefore, the instrument seems a suitable measure for differential assessment of stress management skills in the general population.
