- Gothenburg EMS-system, GoteborgAIM: To evaluate the outcome among patients suffering from out-of-hospital cardiac arrest (OHCA) after the introduction of mechanical chest compression (MCC) compared with standard cardiopulmonary resuscitation (SCPR) in two emergency medical service (EMS) systems. METHODS: The inclusion criterion was witnessed OHCA. The exclusion criteria were age < 18 years, the following judged etiologies behind OHCA: trauma, pregnancy, hypothermia, intoxication, hanging and drowning or return of spontaneous circulation (ROSC) prior to the arrival of the advanced life support (ALS) unit. Two MCC devices were allocated during six-month periods between four ALS units for a period of two years (cluster randomisation). RESULTS: In all, 328 patients fulfilled the criteria for participation and 159 were allocated to the MCC tier (the device was used in 66% of cases) and 169 to the SCPR tier. In the MCC tier, 51% had ROSC (primary end-point) versus 51% in the SCPR tier. The corresponding values for hospital admission alive (secondary end-point) were 38% and 37% (NS). In the subset of patients in whom the device was used, the percentage who had ROSC was 49% versus 50% in a control group matched for age, initial rhythm, aetiology, bystander-/crew-witnessed status and delay to CPR. The percentage of patients discharged alive from hospital after OHCA was 8% versus 10% (NS) for all patients and 2% versus 4%, respectively (NS) for the patients in the subset (where the device was used and the matched control population). CONCLUSION: In this pilot study, the results did not support the hypothesis that the introduction of mechanical chest compression in OHCA improves outcome. However, there is room for further improvement in the use of the device. The hypothesis that this will improve outcome needs to be tested in further prospective trials.

- AIM: To describe health status and psychological distress among in-hospital cardiac arrest (IHCA) survivors in relation to gender.METHODS: This national register study consists of data from follow-up registration of IHCA survivors 3-6 months post cardiac arrest (CA) in Sweden. A questionnaire was sent to the survivors, including measurements of health status (EQ-5D-5L) and psychological distress (HADS).RESULTS: Between 2013 and 2015, 594 IHCA survivors were included in the study. The median values for EQ-5D-5L index and EQ VAS among survivors were 0.78 (q1-q3=0.67-0.86) and 70 (q1-q3=50-80) respectively. The values were significantly lower (p<0.001) in women compared to men. In addition, women reported more problems than men in all dimensions of EQ-5D-5L, except self-care. A majority of the respondents reported no problems with anxiety (85.4%) and/or symptoms of depression (87.0%). Women reported significantly more problems with anxiety (p<0.001) and symptoms of depression (p<0.001) compared to men. Gender was significantly associated with poorer health status and more psychological distress. No interaction effects for gender and age were found.CONCLUSIONS: Although the majority of survivors reported acceptable health status and no psychological distress, a substantial proportion reported severe problems. Women reported worse health status and more psychological distress compared to men. Therefore, a higher proportion of women may be in need of support. Health care professionals should make efforts to identify health problems among survivors and offer individualised support when needed.

- AIM: To describe all patients treated for out-of-hospital cardiac arrest (OHCA) according to the Utstein criteria and their characteristics and outcome with emphasis on whether they were available for early intervention trials. DESIGN: Retrospective analysis of a study where data were collected prospectively. SETTING: The Municipality of Goteborg/Molndal in Sweden. PATIENTS: All patients suffering from out-of-hospital cardiac arrest in the Municipality of Goteborg/Molndal in whom cardiopulmonary resuscitation (CPR) was attempted between May 2003 and May 2005. INTERVENTIONS: Part of the study cohort, i.e. patients with a witnessed, non-traumatic, out-of-hospital cardiac arrest were distributed (cluster) to mechanical (LUCAS) or manual chest compression. RESULTS: The overall survival to discharge from hospital among the 508 patients was 8.5%. The corresponding value for non-cardiac cases was 5.1% and for cardiac cases if crew witnessed 16.1%, bystander witnessed 12.7% and non-witnessed 1.4%. Fifty-nine percent of the patients fulfilled the inclusion criteria for the trial and had no exclusion criteria and 9.7% of these survived to discharge. Ten percent of patients fulfilled the inclusion criteria but were excluded and 20.4% survived to discharge. Thirty-one percent of patients did not fulfil the inclusion criteria and 2.5% survived. Among patients included in the LUCAS group, many of the survivors, 10/13 (77%), experienced a rapid return of spontaneous circulation (ROSC) before the application of the device. CONCLUSION: Among patients with OHCA in whom CPR was started 8.5% survived to hospital discharge and 59% were theoretically available for an early intervention trial. These patients have a different outcome compared with patients not available. However, among those available, the majority of survivors had a rapid ROSC before the application of the intervention (LUCAS). This raises concerns about the potential for early intervention trials to improve outcome after OHCA.

Tidskriftsartikel (refereegranskat)abstract
- AIM: In animal and human studies, measuring the pressure of end tidal carbon dioxide (P(ET)CO2) has been shown to be a practical non-invasive method that correlates well with the pulmonary blood flow and cardiac output (CO) generated during cardiopulmonary resuscitation (CPR). This study aims to compare mechanical active compression-decompression (ACD) CPR with standard CPR according to P(ET)CO2 among patients with out-of-hospital cardiac arrest (OHCA), during CPR and with standardised ventilation. METHODS: This prospective, on a cluster level, pseudo-randomised pilot trial took place in the Municipality of Göteborg. During a 2-year period, all patients aged >18 years suffering an out-of-hospital cardiac arrest (OHCA) of presumed cardiac etiology were enrolled. The present analysis included only tracheally intubated patients in whom P(ET)CO2 was measured for 15 min or until the detection of a pulse-giving rhythm. RESULTS: In all, 126 patients participated in the evaluation, 64 patients in the mechanical chest compression group and 62 patients in the control group. The group receiving mechanical ACD-CPR obtained the significantly highest P(ET)CO2 values according to the average (p=0.04), initial (p=0.01) and minimum (p=0.01) values. We found no significant difference according to the maximum value between groups. CONCLUSION: In this hypothesis generating study mechanical ACD-CPR compared with manual CPR generated the highest initial, minimum and average value of P(ET)CO2. Whether these data can be repeated and furthermore be associated with an improved outcome after OHCA need to be confirmed in a large prospective randomised trial.

Passive leg raising during cardiopulmonary resuscitation in out-of-hospital cardiac arrest--does it improve circulation and outcome?
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Passive leg raising (PLR), to augment the artificial circulation, was deleted from cardiopulmonary resuscitation (CPR) guidelines in 1992. Increases in end-tidal carbon dioxide (P(ET)CO(2)) during CPR have been associated with increased pulmonary blood flow reflecting cardiac output. Measurements of P(ET)CO(2) after PLR might therefore increase our understanding of its potential value in CPR. We also observed the alteration in P(ET)CO(2) in relation to the return of spontaneous circulation (ROSC) and no ROSC.

- AIM: To determine the number of CPR trained adults in Sweden, and the willingness of the non-trained population to attend a CPR course. An additional purpose was to investigate differences related to sex, age, residential area, socio-economic classification and country of origin. METHODS: Five thousand adults in Sweden were surveyed, which yielded 3167 valid responses, a response rate of 63%. The sample was selected at random and stratified to correlate to the geographic distribution of the population. RESULTS: The mean (S.D.) age was 46 (16) years, 54% of the respondents were females and 11% were people of foreign origin. Forty-five percent had participated in some form of CPR training. Younger respondents, those living in rural areas, those born in Sweden, employees, students and military conscripts were trained more frequently in CPR. Of the respondents with no CPR training, 50% expressed a willingness to attend a course. The most common reason for not being trained in CPR was that the respondent did not know such courses existed or that they did not know where to go for training. CONCLUSION: Somewhere between 30 and 45% of the adult population of Sweden had participated in CPR training. Half of the non-trained population was willing to learn CPR but frequently did not know that such courses existed or where they were held. Elderly people, people of foreign origin, or those not included in the workforce were less likely to have participated in CPR training.

- 59 years old. Only 1% had attended the course because of their own or a relative's cardiac disease. Ninety-four per cent believed there was a minor to major risk of serious disease transmission while performing CPR. When predicting their willingness to perform CPR in six scenarios, 17% would not start CPR on a young drug addict, 7% would not perform CPR on an unkempt man, while 97% were sure about starting CPR on a relative and 91% on a known person. In four of six scenarios, respondents from rural areas were significantly more positive than respondents from metropolitan areas about starting CPR. In conclusion, readiness to perform CPR on a known person is high among trained CPR rescuers, while hesitation about performing CPR on a stranger is evident. Respondents from rural areas are more frequently positive about starting CPR than those from metropolitan areas.
