Immobilisering efter trauma: Retrospektiv studie av förekomsten av spinala skador

Bakgrund: Immobilisering är en vedertagen omvårdnadsåtgärd inom dagens prehospitala traumavård, detta trots att det inte finns några randomiserade kontrollerade studier angående åtgärden. Många studier har dock visat att riskerna med immobilisering är många varför det är viktigt att undersöka omvårdnadshandlingen närmare. Syfte: Syftet med studien var att undersöka förekomsten av radiologiskt fastställda spinala skador hos patienter som immobiliserats prehospitalt efter trauman, samt på vilka indikationer denna immobilisering gjordes. Metod: En kvantitativ retrospektiv studie där 288 journaler granskades i ambulansens journalsystem MobiMed 3.0 och i sjukhusets journalsystem Cosmic. Därefter analyserades resultaten i SPSS deskriptivt och grafiskt, med chi2-test samt med oberoende t-test. Resultat: Resultatet visade att av de 246 patienter som genomgått en radiologisk undersökning fanns en konstaterad spinal skada hos 48 patienter, vilket motsvarade cirka 17 %. Alla inkluderade patienter hade varit utsatta för trubbigt våld och den vanligaste indikationen för immobilisering var smärta/ömhet över kotpelaren. Medelåldern hos patienterna med spinala skador var signifikant högre än medelåldern hos de utan spinala skador och en signifikant skillnad fanns mellan patienterna med spinal skada och utan spinal skada och samtidig smärta/ömhet över kotpelaren. Slutsats: Ett större antal patienter uppvisade skador i denna studie jämfört med tidigare studier, hos den stora majoriteten fanns dock inga spinala skador. Detta innebär att patienterna utsätts för en potentiellt onödig omvårdnadsåtgärd som är svagt vetenskapligt underbyggd och medför ett flertal risker. Fler studier inom området behövs för att kunna minska patienters potentiella lidande i och med att immobiliseras prehospitalt. Background: Spinal immobilization is an established practice in today’s prehospital trauma care. This even though there is a lack of randomized controlled studies regarding this practice. Many studies points to the risks regarding spinal immobilization why it is of importance to further examine the practice. Aim: The aim of this study was to investigate the incidence of radiologically confirmed spinal injuries in patients immobilized after prehospital trauma and on what indications this immobilization was done Method: A quantitative retrospective study of 288 medical records acquired from the ambulance medical record system Mobimed 3.0 and the hospital's medical record Cosmic were examined. The results were analyzed in SPSS descriptive and graphic, with chi2-test and independent t-test. Result: The results show that of the 246 patients who underwent a radiological examination, 46 had a spinal injury, approximately 17 %. All of the included patients had been exposed to blunt trauma and the most common indication for immobilization was pain/tenderness over the spine. The mean age of the patients with spinal injuries was significantly higher than the mean age of those without spinal injuries. A significant difference was also found between patients with pain/tenderness over the spine and spinal injury and those without spinal injury. Conclusion: A greater number of patients had a spinal injury in this study compared with previous studies, although the majority of the patients had no spinal injury. This means that the majority of the patients were exposed to a potentially unnecessary procedure that lacks scientifically evidence. More studies about immobilization are required to reduce the patients' potential suffering in connection with prehospital immobilization.

Alkoholvanor, träningsvanor och upplevd hälsa på läkarprogrammet och sjuksköterskeprogrammet

Bakgrund: Studenter har en hög konsumtion av alkohol och tränar i stor utsträckning. Alkohol i stora mängder har en negativ effekt på hälsan och träning har en positiv effekt på hälsan. Studenters upplever generellt sett sin hälsa som god. Syfte: Att undersöka alkoholvanor, träningsvanor och upplevd hälsa hos studenter på läkar-och sjuksköterskeprogrammet och undersöka eventuella samband och skillnader. Metod: Studien är en deskriptiv enkätstudie med 236 deltagare från läkar-och sjuksköterskeprogrammets termin ett och fyra. Resultat: Studenterna drack alkohol och intensivkonsumerade alkohol ofta. De tränade också ofta, upplevde liten påverkan av alkoholvanor på träningsvanor och upplevd hälsa. Med ökad ålder minskade alkoholkonsumtionen, läkarstudenter upplevde sin fysiska hälsa som bättre än vad sjuksköterskestudenterna gjorde och de studenter som tränade mycket upplevde sin fysiska hälsa som bättre än de studenter som inte tränade så mycket. Slutsats: Studenters alkohol-och träningsvanor och upplevda hälsa i studien visade stora likheter med tidigare forskning. Mindre andel än förväntat upplevde att alkoholintag hade en negativ påverkan på träningen. Mer forskning behövs inom området för att klargöra säkrare samband mellan faktorerna. Ökad kunskap om studenters alkoholvanor kan ge bättre underlag vid folkhälsofrämjande arbete

Physiological respiratory parameters in pre-hospital patients with suspected COVID-19 : A prospective cohort study

Background The COVID-19 pandemic has presented emergency medical services (EMS) worldwide with the difficult task of identifying patients with COVID-19 and predicting the severity of their illness. The aim of this study was to investigate whether physiological respiratory parameters in pre-hospital patients with COVID-19 differed from those without COVID-19 and if they could be used to aid EMS personnel in the prediction of illness severity. Methods Patients with suspected COVID-19 were included by EMS personnel in Uppsala, Sweden. A portable respiratory monitor based on pneumotachography was used to sample the included patient's physiological respiratory parameters. A questionnaire with information about present symptoms and background data was completed. COVID-19 diagnoses and hospital admissions were gathered from the electronic medical record system. The physiological respiratory parameters of patients with and without COVID-19 were then analyzed using descriptive statistical analysis and logistic regression. Results Between May 2020 and January 2021, 95 patients were included, and their physiological respiratory parameters analyzed. Of these patients, 53 had COVID-19. Using adjusted logistic regression, the odds of having COVID-19 increased with respiratory rate (95% CI 1.000-1.118), tidal volume (95% CI 0.996-0.999) and negative inspiratory pressure (95% CI 1.017-1.152). Patients admitted to hospital had higher respiratory rates (p<0.001) and lower tidal volume (p = 0.010) compared to the patients who were not admitted. Using adjusted logistic regression, the odds of hospital admission increased with respiratory rate (95% CI 1.081-1.324), rapid shallow breathing index (95% CI 1.006-1.040) and dead space percentage of tidal volume (95% CI 1.027-1.159). Conclusion Patients taking smaller, faster breaths with less pressure had higher odds of having COVID-19 in this study. Smaller, faster breaths and higher dead space percentage also increased the odds of hospital admission. Physiological respiratory parameters could be a useful tool in detecting COVID-19 and predicting hospital admissions, although more research is needed

Suction cup on a piston-based chest compression device improves coronary perfusion pressure and cerebral oxygenation during experimental cardiopulmonary resuscitation

Introduction: The presented study aimed to investigate whether a mechanical chest compression piston device with a suction cup assisting chest recoil could impact the hemodynamic status when compared to a bare piston during cardiopulmonary resuscitation. Methods: 16 piglets were anesthetized and randomized into 2 groups. After 3 minutes of induced ventricular fibrillation, a LUCAS 3 device was used to perform chest compressions, in one group a suction cup was mounted on the device's piston, while in the other group, compressions were per -formed by the bare piston. The device was used in 30:2 mode and the animals were manually ventilated. Endpoints of the study were: end tidal carbon dioxide, coronary and cerebral perfusion pressures, and brain oxygenation (measured using near infrared spectroscopy). At the end of the protocol, the animals that got a return to spontaneous circulation were observed for 60 minutes, then euthanized. Results: No difference was found in end tidal carbon dioxide or tidal volumes. Coronary perfusion pressure and cerebral oxygenation were higher in the Suction cup group over the entire experiment time, while cerebral perfusion pressure was higher only in the last 5 minutes of CPR. A passive tidal volume (air going in and out the airways during compressions) was detected and found correlated to end tidal carbon dioxide. Conclusions: The use of a suction cup on a piston-based chest compression device did not increase end tidal carbon dioxide, but it was associated to a higher coronary perfusion pressure

Continuous chest compressions are associated with higher peak inspiratory pressures when compared to 30:2 in an experimental cardiac arrest model

BACKGROUND: Ventilation during cardiopulmonary resuscitation (CPR) has long been a part of the standard treatment during cardiac arrests. Ventilation is usually given either during continuous chest compressions (CCC) or during a short pause after every 30 chest compressions (30:2). There is limited knowledge of how ventilation is delivered if it effects the hemodynamics and if it plays a role in the occurrence of lung injuries. The aim of this study was to compare ventilation parameters, hemodynamics, blood gases and lung injuries during experimental CPR given with CCC and 30:2 in a porcine model. METHODS: Sixteen pigs weighing approximately 33 kg were randomized to either receive CPR with CCC or 30:2. Ventricular fibrillation was induced by passing an electrical current through the heart. CPR was started after 3 min and given for 20 min. Chest compressions were provided mechanically with a chest compression device and ventilations were delivered manually with a self-inflating bag and 12 l/min of oxygen. During the experiment, ventilation parameters and hemodynamics were sampled continuously, and arterial blood gases were taken every five minutes. After euthanasia and cessation of CPR, the lungs and heart were removed in block and visually examined followed by sampling of lung tissue which were examined using microscopy. RESULTS: In the CCC group and the 30:2 group, peak inspiratory pressure (PIP) was 58.6 and 35.1 cmH2O (p < 0.001), minute volume (MV) 2189.6 and 1267.1 ml (p < 0.001), peak expired carbon dioxide (PECO2) 28.6 and 39.4 mmHg (p = 0.020), partial pressure of carbon dioxide (PaCO2) 50.2 and 61.1 mmHg (p = 0.013) and pH 7.3 and 7.2 (p = 0.029), respectively. Central venous pressure (CVP) decreased more over time in the 30:2 group (p = 0.023). All lungs were injured, but there were no differences between the groups. CONCLUSIONS: Ventilation during CCC resulted in a higher PIP, MV and pH and lower PECO2 and PaCO2, showing that ventilation mode during CPR can affect ventilation parameters and blood gases
