Results: Retrospective method has been used to analyze theperiod from January to December 2012. From a total of 116 patientsin cardiac arrest 4 patients were taken to the infirmary emergencymedicine and 112 patients were treated at the site of the incident.Average response time of emergency medical team was 6.35 min.Of the total number 21.5% patients had shockable rhythm on themonitor. Return of spontaneous circulation – ROSC – is achieved in17.25% of patients.

Cardiopulmonary resuscitation performed by bystenders at thescene increases the survival rate of 2–3 times. Experience ofemergency medical teams in the implementation of early car-diopulmonary resuscitation performed by bystenders includingother health professionals (primary care workers) is devastating.Neither one of victims of cardiac arrest receive cardiopulmonaryresuscitation until the arrival of emergency medical team.

Conclusion: It is necessary to develop programs to raise aware-ness among the population about the importance of providingassistance to victims of cardiac arrest, as well as education pro-grams of basic cardiopulmonary resuscitation and AED use. Goodequipment, organization and education of emergency medicalteam to care for victims of cardiac arrest is crucial to improvingsurvival.

Role of the emergencies coordinating centermanaging an OHCA call and its influence on thevariables that may improve the outcome of theEMS response

Objectives: To define variables occurring in the lapse betweenreception of an OHCA-call and arrival of ALS-Team to evaluate theirinfluence on the outcome of EMS response.

Rates of telephonic diagnosis of OHCA and DA-CPR, times of acti-vation and mobilization of ALS-Team and rates of bystanders CPRare related to the ratio of survival at hospital arrival.

Materials and methods: Descriptive study of the OHCA assistedby SAMU-Asturias from July 1st to September 30th 2013. Dataextracted from medical records and UTSTEIN data base, andprocessed using SPSS Statistics 21 programme.

Results: 90 cases meet the criteria for inclusion: OHCA with esti-mated collapse time prior to call time. Activation cause: OCHA in65.6% of cases with DA-CPR was provided in 46.6% of them. OHCAdiagnosed “in call” mean activation (154.0 s, s = 83.9) and mobiliza-tion (105.9 s, s = 74.6) times do not statistically differ (p > 0,05) fromthose when it is not diagnosed (138.3 s, s = 53.5 and 85.5 s, s = 71.2,although mean activation and mobilization times recorded in “aliveat hospital arrival” group (120.7 s, s = 49. and 64.2 s, s = 40.7) aresmaller than those recorded in “non ROSC” group (158.0 s, s = 80.2and 110.7 s, s = 78.4) (p < 0.05). OHCA identified calls get bystandersCPR in 41.9% of cases, while on other calls it is in 17.2% (p < 0.05).DA-CPR get bystanders CPR in 60% of cases, opposed to 15.9% ifnot (p < 0.05). In the “alive at hospital arrival” group 65.7% gotbystanders CPR, while in the “non ROSC” group 21.8% got it.

Conclusions: Telephonic diagnosis of OHCA increases the rateof bystanders CPR, thus it implies DA-CPR, improving our survivalrate. Other variables studied are not modified significantly. It isimperative to increase the sensibility of the dispatcher to diagnose

OHCA to, and combined with widespread CPR education, improvethe survival rate in OHCA.

Background: This study is justified by the need to dispose arapid vascular access for the administration of drugs, in patientsunder resuscitation with difficult peripheral veins in emergencyoutside the hospital. Current European Resuscitation Council (ER)Guidelines recommend intraosseous (IO) vascular access if intravenous (IV) access is difficult to administer. A comparative ofintraosseous study, compared the central venous access and theaccess via IO in adult under resuscitation with an inaccessibleperipheral vein in emergency. In conclusion the IO access is moreeffective with higher success rate on first attempt and a lower pro-cedure time.

Methods: Observational study. Study period: from January2011 to January 2014. Sample: patients assisted by EMS 061-Jaen. Database: CMBD Public Company for Health Emergencies anddocumentation of cases of CPR in which professionals used theintraosseous drill.

Results: The study used 100% of the cases (20 cases) of CPR inwhich the intraosseous access device was used.

Data obtained:

Patients age: 4 children (under 12 years) (20%) and 16 adults (80%).Puncture site: proximal tibia 14 (70%) distal tibia 5 (25%) proximalhumerus 1 (5%)Children: Proximal Tibia: 4 (100%)Adults: Proximal Tibia: 10 (62.5%) distal tibia: 5 (31.25%) proximalhumerus: 1 (6.25Results puncture: Strength: 15 (75%) No effective: 5 (25%)Children: Strength: 3 (75%) No effective: 1 (25%)Adults: Strength: 12 (75%) No staff: 4 (25%).

Conclusion: The intraosseous access as an alternative to thosesituations where it is not possible peripheral venous access, itbecomes a real and reliable alternative, fast implementation andhigh success rate of CPR in which administration is required press-ing of drugs and fluids.
