Interrater agreement between student and teacher assessments of endotracheal intubation skills in a self-directed simulation learning environment.

BACKGROUND: Practical skill assessment is an important part of the learning process to confirm competencies in acquired medical knowledge. OBJECTIVE: This study aimed to compare the assessments of endotracheal intubation skills using the HybridLab® methodology between students and teacher in terms of interobserver reliability. METHODS: Reliability analysis was performed with observational data (data are reported according to STROBE guidelines). The study was conducted in two countries, the Lithuanian University of Health Science (LUHS) and Pennsylvania State University (PSU) in the US, between 1 January and 30 June 2020. A total of 92 students (60 from LUHS and 32 from PSU) were trained in endotracheal intubation using an algorithm-driven hybrid learning method. At the end of the training session, the participants had to complete the evaluation scenario, which was assessed by one of the students and evaluated remotely by a single teacher. The student assessment of the endotracheal intubation procedure was compared with the teacher's assessment using correlation and estimation of the intraclass correlation coefficient. RESULTS: Overall, the medians of the student and teacher assessments were both 100% (0%). Spearman's correlation coefficient between the student and teacher assessments was 0.879 (p = 0.001). The intraclass correlation coefficient used for interobserver variations between the students and teacher was 0.883 (95% confidence interval from 0.824 to 0.923). CONCLUSIONS: The algorithm-driven hybrid learning method allows students to reliably assess endotracheal intubation skills to a level comparable with that of the teacher's evaluation. This learning method has the potential to be a cost-effective and efficient way to provide high-quality education while also saving human resources.

Short- and long-term survival after out-of-hospital cardiac arrest in Kaunas (Lithuania) from 2016 to 2018.

BACKGROUND: No studies analysing out-of-hospital cardiac arrest (OHCA) epidemiology and outcomes in Lithuania were published in the last decade. METHODS: We conducted a retrospective analysis of prospectively collected data. The incidence of OHCA and the demographics and outcomes of patients who were treated for OHCA between 1 and 2016 and 31 December 2018 at Kaunas Emergency Medical Service (EMS) were collected and are reported in accordance with the Utstein recommendations. Multivariable logistic regression analysis was used to identify predictors of survival to hospital discharge. RESULTS: In total, 838 OHCA cases of EMS-treated cardiac arrest (CA) were reported (95.8 per 100.000 inhabitants). The median age was 71 (IQR 58-81) years of age, and 66.7% of patients were males. A total of 73.8% of OHCA cases occurred at home, 59.3% were witnessed by a bystander, and 54.5% received bystander cardiopulmonary resuscitation. The median EMS response time was 10 min. Cardiac aetiology was the leading cause of CA (78.8%). The initial rhythm was shockable in 27.6% of all cases. Return of spontaneous circulation at hospital transfer was evident in 24.9% of all cases. The survival to hospital discharge rate was 10.9%, and the 1-year survival rate was 6.9%. The survival to hospital discharge rate in the Utstein comparator group was 36.1%, and the 1-year survival rate was 27.2%. Five factors were associated with improved survival to hospital discharge: shockable rhythm, time from call to arrival at the patient less than 10 min, witnessed OHCA, age < 80 years, and male sex. CONCLUSION: This is the first OHCA study from Lithuania examining OHCA epidemiology and outcomes over a three year period. Routine OHCA data collection and analysis will allow us to track the efficacy of service improvements and should become a standard practice in all Lithuanian regions. TRIAL REGISTRATION: This research was registered in the clinicaltrials.gov database: Identifiers: NCT04784117, Unique Protocol ID: LITOHCA. Brief Title: Out-of-hospital Cardiac Arrest Epidemiology and Outcomes in Kaunas 2016-2021.

A novel algorithm-driven hybrid simulation learning method to improve acquisition of endotracheal intubation skills: a randomized controlled study.

BACKGROUND: Simulation-based training is a clinical skill learning method that can replicate real-life situations in an interactive manner. In our study, we compared a novel hybrid learning method with conventional simulation learning in the teaching of endotracheal intubation. METHODS: One hundred medical students and residents were randomly divided into two groups and were taught endotracheal intubation. The first group of subjects (control group) studied in the conventional way via lectures and classic simulation-based training sessions. The second group (experimental group) used the hybrid learning method where the teaching process consisted of distance learning and small group peer-to-peer simulation training sessions with remote supervision by the instructors. After the teaching process, endotracheal intubation (ETI) procedures were performed on real patients under the supervision of an anesthesiologist in an operating theater. Each step of the procedure was evaluated by a standardized assessment form (checklist) for both groups. RESULTS: Thirty-four subjects constituted the control group and 43 were in the experimental group. The hybrid group (88%) showed significantly better ETI performance in the operating theater compared with the control group (52%). Further, all hybrid group subjects (100%) followed the correct sequence of actions, while in the control group only 32% followed proper sequencing. CONCLUSIONS: We conclude that our novel algorithm-driven hybrid simulation learning method improves acquisition of endotracheal intubation with a high degree of acceptability and satisfaction by the learners' as compared with classic simulation-based training.

How the changes in the system affect trauma care provision: The assessment of and implications for Lithuanian trauma service performance in 2007-2012.

OBJECTIVE: The aim of this study was to identify and assess the effects of changes in the Lithuanian trauma service from 2007 to 2012. We postulate that the implications derived from this study will be of importance to trauma policy planners and makers in Lithuania and throughout other countries of Eastern and Central Europe. MATERIALS AND METHODS: Out of 10,390 trauma admissions to four trauma centers in 2007, 294 patients (2.8%) were randomly selected for the first arm of a representative study sample. Similarly, of 9918 trauma admissions in 2012, 250 (2.5%) were randomly chosen for comparison in the study arm. Only cases with a diagnosis falling into the ICD-10 "S" and "T" codes were included. A survey of whom regarding changes in quality of trauma care from 2007 to 2012 was carried out by emergency medical service (EMS) providers. RESULTS: The Revised Trauma Score (RTS) mean value was 7.45±1.04 for the 2007 year arm; it was 7.53±0.93 for the 2012 year arm (P=0.33). Mean time from the moment of a call from the site of the traumatic event to the patient's arrival at the trauma center did not differ between the arms of the sample: 49.95min in 2007 vs. 51.6min in 2012 (P=0.81). An application of the operational procedures such as a cervical spine protection using a hard collar, oxygen therapy, infusion of intravenous fluids, and pain relief on the trauma scene was more frequent in 2012 than in 2007. Management of trauma patients in the emergency department improved regarding the availability of 24/7 computed tomography scanner facilities and an on-site radiographer. Time to CT-scanning was reduced by 38.8%, and time to decision-making was reduced by 16.5% in 2012. CONCLUSIONS: Changes in operational procedures in the Lithuanian pre-hospital care provision and management of trauma patients in emergency departments of trauma centers improved the efficiency of trauma care delivery over the 2007-2012 period.

Microcirculatory, mitochondrial, and histological changes following cerebral ischemia in swine.

BACKGROUND: Ischemic brain injury due to stroke and/or cardiac arrest is a major health issue in modern society requiring urgent development of new effective therapies. The aim of this study was to evaluate mitochondrial, microcirculatory, and histological changes in a swine model of global cerebral ischemia. RESULTS: In our model, significant microcirculatory changes, but only negligible histological cell alterations, were observed 3 h after bilateral carotid occlusion, and were more pronounced if the vascular occlusion was combined with systemic hypotension. Analysis of mitochondrial function showed that LEAK respiration (measured in the presence of pyruvate + malate but without ADP) was not affected in any model of global cerebral ischemia in pigs. The OXPHOS capacity with pyruvate + malate as substrates decreased compared with the control levels after bilateral carotid artery occlusion, and bilateral carotid artery occlusion + hypotension by 20% and 79%, respectively, resulting in decreases in the respiratory control index of 14% and 73%, respectively. OXPHOS capacity with succinate as a substrate remained constant after unilateral carotid artery occlusion or bilateral carotid artery occlusion, but decreased by 53% after bilateral carotid artery occlusion and hypotension compared with controls (p < 0.05, n = 3-6). Addition of exogenous cytochrome c to mitochondria isolated from ischemia brains had no effect on respiration in all models used in this study. CONCLUSIONS: We found a decrease in microcirculation and mitochondrial oxidative phosphorylation activity, but insignificant neuronal death, after 3 h ischemia in all our pig models of global cerebral ischemia. Dysfunction of the mitochondrial oxidative phosphorylation system, particularly damage to complex I of the respiratory chain, may be the primary target of the ischemic insult, and occurs before signs of neuronal death can be detected.

Impact of video recordings review with structured debriefings on trauma team performance: a prospective observational cohort study.

PURPOSE: To determine the impact of structured debriefings (SD) with audio/video review of trauma patients' resuscitation events on trauma team (TT) technical and non-technical skills. METHODS: Single-center prospective observational cohort study. The study included all emergency department patients aged 18 years or older who received resuscitation from the TT. Virtual meeting was held with the TT using SD to review one trauma patient resuscitation video. Technical skills improvement was based on adherence to the ATLS protocol and non-technical skills based on T-NOTECHS scale. RESULTS: There was statistically significant improvement in adherence to the ATLS protocol: 73% [55-82%] vs 91% [82-100%] (p < 0.001); and improvement in T-NOTECHS scale: 12 [10-14] vs 16 [14-19] points (p < 0.001). CONCLUSION: In this study, we found that structured debriefings with review of patients' resuscitation video recordings can have a significant positive impact on trauma team performance in the emergency department in both technical and non-technical skills.

Can lightweight rescuers adequately perform CPR according to 2010 resuscitation guideline requirements?

AIM: To evaluate associations between rescuers' anthropometric characteristics and chest compressions (CC) depth according to 2010 resuscitation guidelines. METHODS: 186 medical and pharmacy students, never trained in basic life support (BLS) before, underwent video self-instruction training. The participants were asked to perform a BLS test on a manikin connected to a PC for 6 min immediately after training, and the quality of the cardiopulmonary resuscitation (CPR) skills was evaluated. RESULTS: Women with body weights less than 56 kg were 6.29 times more likely to produce insufficient CCs than women weighing 56-62.7 kg, and 4.72 times more likely to produce insufficient CCs compared with women weighing more than 62.7 kg. CONCLUSIONS: Lightweight rescuers may have difficulty achieving the full compression depth of 5-6 cm required by new resuscitation guidelines. These rescuers require special attention during CPR training, with an emphasis on correct body positioning and use of body weight for CCs.

Electronic field protocols for prehospital care quality improvement in Lithuania: a randomized simulation-based study.

BACKGROUND: Prehospital emergency care is complex and influenced by various factors, leading to the need for decision-support tools. Studies suggest that cognitive aids improve provider performance and patient outcomes in clinical emergencies. Electronic cognitive aids have rarely been investigated in prehospital care. Therefore, this study aimed to evaluate the effects of the electronic field protocol (eFP) module on performance, adherence to the standard of care, and satisfaction of prehospital care providers in a simulated environment. METHODS: This randomised simulation-based study was conducted at the Lithuanian University of Health Sciences in Kaunas, Lithuania. The simulation scenarios were developed to test 12 eFPs: adult resuscitation, pediatric resuscitation, delivery and postpartum care, seizures in pregnancy, stroke, anaphylaxis, acute chest pain, acute abdominal pain, respiratory distress in children, severe trauma, severe infection and sepsis, and initial neonatal evaluation and resuscitation. Sixteen prehospital practitioners with at least 3 years of clinical experience were randomly assigned to either use the eFP module or perform without it in each of the 12 simulated scenarios. Participant scores and adherence to standardised checklists were compared between the two performance modes. Participant satisfaction was measured through a post-simulation survey. RESULTS: A total of 190 simulation sessions were conducted. Compared to the use of memory alone, the use of the eFP module significantly improved participants' performance in 10 out of the 12 simulation scenarios. Adherence to the standardised checklist increased from 60 to 85% (p < 0.001). Post-simulation survey results indicate that participants found the eFP module easy to use and relevant to prehospital clinical practice. CONCLUSIONS: The study findings suggest that the eFP module as a cognitive aid can enhance prehospital practitioners' performance and adherence to the standard of care in simulated scenarios. These results highlight the potential of standardised eFPs as a quality improvement step in prehospital care in Lithuania.

AI-Enabled Public Surveillance Cameras for Rapid Emergency Medical Service Activation in Out-of-Hospital Cardiac Arrests.

This study aims to evaluate the potential usefulness of a novel artificial intelligence (AI)-based video processing algorithm for rapidly activating ambulance services (EMS) in unwitnessed out-of-hospital cardiac arrest (OHCA) cases in public places. We hypothesized that AI should activate EMS using public surveillance cameras after detecting a person fallen due to OHCA. We created an AI model based on our experiment performed at the Lithuanian University of Health Sciences, Kaunas, Lithuania, in Spring 2023. Our research highlights the potential benefits of AI-based surveillance cameras for rapidly detecting and activating EMS during cardiac arrests.

Early course of microcirculatory perfusion in eye and digestive tract during hypodynamic sepsis.

INTRODUCTION: The aim of the study was to evaluate and compare the microcirculatory perfusion during experimental sepsis in different potentially available parts of the body, such as sublingual mucosa, conjunctiva of the eye, and mucosa of jejunum and rectum. METHODS: Pigs were randomly assigned to sepsis (n = 9) and sham (n = 4) groups. The sepsis group received a fixed dose of live Escherichia coli infusion over a 1-hour period (1.8 × 10(9)/kg colony-forming units). Animals were observed 5 hours after the start of E. coli infusion. In addition to systemic hemodynamic assessment, we performed conjunctival, sublingual, jejunal, and rectal evaluation of microcirculation by using Sidestream Dark Field (SDF) videomicroscopy at the same time points: at baseline, and at 3 and 5 hours after the start of live E. coli infusion. Assessment of microcirculatory parameters of convective oxygen transport (microvascular flow index (MFI) and proportion of perfused vessels (PPV)), and diffusion distance (perfused vessel density (PVD) and total vessel density (TVD)) was done by using a semiquantitative method. RESULTS: Infusion of E. coli resulted in a hypodynamic state of sepsis associated with low cardiac output and increased systemic vascular resistance despite fluid administration. Significant decreases in MFI and PPV of small vessels were observed in sublingual, conjunctival, jejunal, and rectal locations 3 and 5 hours after the start of E. coli infusion in comparison with baseline variables. Correlation between sublingual and conjunctival (r = 0.80; P = 0.036), sublingual and jejunal (r = 0.80; P = 0.044), and sublingual and rectal (r = 0.79; P = 0.03) MFI was observed 3 hours after onset of sepsis. However, this strong correlation between the sublingual and other regions disappeared 5 hours after the start of E. coli infusion. Overall, the sublingual mucosa exhibited the most-pronounced alterations of microcirculatory flow in comparison with conjunctival, jejunal, and rectal microvasculature (P < 0.05). CONCLUSIONS: In this pig model, a time-dependent correlation exists between sublingual and microvascular beds during the course of a hypodynamic state of sepsis.

Microvascular distribution in the ocular conjunctiva and digestive tract in an experimental setting.

UNLABELLED: Recently improved microcirculatory imaging techniques, such as orthogonal polarization spectral (OPS) and its technical successor sidestream dark field (SDF) imaging, in handheld devices have allowed a direct observation of the microcirculation at the bedside. Usually a cut-off of 20 µm in diameter is used to differentiate small vessels (mainly capillaries) from large vessels (mainly venules) during this technique. We hypothesized that it was possible to measure the small vessels with a considerably smaller inner diameter. MATERIAL AND METHODS: Images of the sublingual, conjunctival, jejunal, and rectal mucosa microcirculation were obtained with SDF videomicroscopy (Microscan®, Microvision Medical, Amsterdam, the Netherlands). Using the validated software, the length and diameter of microvessels were manually traced with a computer-generated line. All vessels were divided into the groups according to the inner diameter. RESULTS: A total of 156 SDF images of the sublingual, ocular conjunctival, jejunal, and rectal mucosa were taken in 13 pigs. The length of microscopic vessels progressively increased with a decrease in the vessel diameter less than 8 mm in all the lodges, such as sublingual (80.6% of total vessel length), ocular conjunctival (76.5% of total vessel length), jejunal (99.8% of total vessel length), and rectal (97.8% of total vessel length), due to capillary network formation. There was no significant difference in the distribution of vessels from 0 to 10 µm in diameter comparing sublingual and eye conjunctival as well as jejunal and rectal mucosa. CONCLUSION: In pigs, small-diameter microscopic vessels (<10 µm) dominated in all the studied lodges (sublingual, ocular conjunctival, jejunal, and rectal mucosa), and this is evidence to establish a new cut-off for capillaries in microcirculatory analysis of SDF imaging in experimental and clinical studies.

Impact of the COVID-19 lockdown on trauma team activations in a single major Lithuanian trauma center: A retrospective single-center study.

Background: As a result of the coronavirus disease 2019 (COVID-19) pandemic and national quarantine, different levels of social and movement restrictions, and stay-at-home requests, trauma trends have changed. The aim of the present study was to determine the impact of lockdown on patients treated by the trauma team (TT) at a single major Lithuanian trauma center during the COVID-19 pandemic. Methods: This is a retrospective, descriptive study of adult (≥18 years old) trauma patients (for whom the TT was activated). Consequently, we analyzed the national lockdown periods from 16 March to 15 May 2020 and from 16 December 2020 to 28 February 2021, compared with the corresponding period of the previous year. Results: There was a 10% reduction in TT activations during the national lockdown period. No significant differences were noted in patient demographics. In the COVID-19 cohort, patients had higher Injury Severity Score (14 [IQR 6-21] vs. 9 [IQR 3-18], P = 0.025) and longer time to computed tomography scan (33 [IQR 25-43] vs. 23 [IQR 20-31] min, P < 0.001). Moreover, in the COVID-19 cohort, three times more patients were transferred from the emergency department (ED) straight to the operating room (n = 12 [19%] vs. n = 4 [5.7%], P = 0.018, Cramer's V = 0.21). Conclusion: Patients were more severely injured, and more patients required emergent surgery during the lockdown. In addition, it took longer to transfer patients to the ED and to perform a computed tomography scan.

New insights for adult cardiopulmonary resuscitation. Up-coming resuscitation guidelines 2010.

Despite advances in cardiac arrest care, the overall survival to hospital discharge remains poor. The objective of this paper was to review the innovations in cardiopulmonary resuscitation that could influence survival or change our understanding about cardiopulmonary resuscitation. We have performed a search in the MEDLINE and the Cochrane databases for randomized controlled trials, meta-analyses, expert reviews from December 2005 to March 2010 using the terms cardiac arrest, basic life support, and advanced life support. The lack of randomized trials during the last 5 years remains the main problem for crucial decisions in cardiopulmonary resuscitation. Current trends in cardiopulmonary resuscitation are toward minimizing the interruptions of chest compressions and improving the quality of cardiopulmonary resuscitation. In addition, attention should be paid to all the parts of chain of survival, which remains essential in improving survival rates.

What happens in the shock room stays in the shock room? A time-based audio/video audit framework for trauma team performance analysis.

INTRODUCTION: A precise tool for analysis of trauma team performance is missing. OBJECTIVES: To create a framework for trauma team performance analysis and feedback. METHODS: An observational study in a level I trauma centre in Lithuania was performed from January 1 2017 to August 31 2017. Audio/video review process was used to evaluate technical and nontechnical performance of the trauma team. RESULTS: In total, 143 trauma team activations were analysed. The mean rate of completion for the primary survey based on Advanced Trauma Life Support principles was 68.5%. Technical steps of patient resuscitation were measured in seconds during first hour of the treatment. The T-NOTECHS scale mean score was 11.99 (SD 2.9). CONCLUSION: During the study period, we were able to measure the time needed for certain steps in trauma patient evaluation and management. Based on this analysis, a performance improvement program will be devised, including the HybridLab medical simulation, audio/video debriefing, and individualised feedback sessions.

Initial neonatal resuscitation: skill retention after the implementation of the novel 24/7 HybridLab® learning system.

BACKGROUND: Ensuring long-term retention of the acquired practical skills is one of the major aims of a medical school. This depends on the application of training techniques and their combinations. In order to standardize the teaching process, to acquire and maintain a broad array of technical, professional, and interpersonal skills and competencies, and to improve the retention of practical skills, we developed a new training technique - the HybridLab® learning method. It consists of an e-learning platform, hands-on simulation, carefully elaborated learning algorithms (DRAKON), peer-to-peer teaching, and assessment and feedback by peers, and later - by a remote instructor. Summary of the work: The subjects of the study were fifth-year students of the Lithuanian University of Health Sciences Medical Academy who during 2014-2015 were studying the obstetrics and gynecology module in the neonatology cycle. We analyzed the retention of practical skills in the initial neonatal resuscitation among students who were training with the use of our developed HybridLab® technique at 6 and 12 months after the completion of the cycle. SUMMARY OF RESULTS: After 6 and 12 months, mean changes in the subjects' evaluation scores (percentage drop-off between the first and the second total score) dropped by, respectively, 31.8% (SD: 27.5) and 7.7% (SD: 25.6), and did not differ statistically significantly (p = .2). In the group of subjects who were not given a possibility to remember the skills and the course of initial neonatal resuscitation, the mean change between the first and the second total evaluation scores was 42.5% (SD: 26.7). In students who were given such possibility, the mean change between the first and the second total evaluation scores was significantly smaller -12.7% (SD: 13.8) (p < .001). Changes in the evaluation scores of individual skills (first steps, mouth-to-mouth ventilation, and chest compressions) between the first and the second evaluation also differed statistically significantly and were smaller in the group of students who were given a possibility to remember their skills (p < .001). DISCUSSION: The HybridLab® learning method is a novel technique, and thus more studies are required to evaluate the significance of the HybridLab® technique for long-time retention of practical skills. CONCLUSION: As a result of the application of the HybridLab® training technique, practical skill retention among medical students after 6 and 12 months dropped by only about 13%. A recall system significantly improved practical skill retention.

EMS systems in Lithuania.

In Lithuania pre-hospital medical services were started at the end of the 19th century. Emergency care for patients is provided free of charge and funded from a Compulsory Health Insurance Fund and by Government. Ambulance response target times are 15 min in urban areas and up to 30 min in rural areas. Personnel on ambulances consist of nurses and physicians. In the near future it is expected that paramedics will replace ambulance drivers. The emergency medical system is in a transition period: Admission departments are developing into emergency departments, residency programmes for emergency medicine are being prepared, and emergency medicine is going to be recognised as a separate specialty.

The dependence of successful resuscitation on electrocardiographically documented cardiac rhythm in case of out-of-hospital cardiac arrest.

OBJECTIVE: To determine the influence of electrocardiographically documented cardiac rhythm during sudden cardiac arrest on successful resuscitation among out-of-hospital deaths in Kaunas city. MATERIAL AND METHODS: An observational prospective study was conducted between 1 January, 2005, and 30 December, 2005, in Kaunas city with a population of 360,627 inhabitants. In this period, all cases of cardiac arrest were analyzed according to the guidelines of the Utstein consensus conference. Cardiac arrest (both of cardiac and noncardiac etiology) was confirmed in 72 patients during one year. Effective cardiopulmonary resuscitation was performed in 18 patients. RESULTS: The total number of deaths from all causes in Kaunas during 1-year study period was 6691. Sixty-two patients due to sudden death of cardiac etiology were resuscitated by emergency medical services personnel. Return of spontaneous circulation was achieved in 11 patients. Ventricular fibrillation was observed in 33 (53.2%) patients. Asystole was present in 11 (17.7%) and other rhythms in 18 (29.1%) cases. Patients with ventricular fibrillation as an initial rhythm were more likely to be successfully resuscitated than patients with asystole. CONCLUSIONS: Ventricular fibrillation was the most common electrocardiographically documented cardiac rhythm registered during cardiac arrest in out-of-hospital settings. Ventricular fibrillation as a mechanism of cardiac arrest was associated with major cases of successful resuscitation.

The ability of Lithuanian ambulance services to provide first medical aid in trauma cases.

OBJECTIVE: To evaluate the ability of country ambulance services to provide first medical aid in trauma cases. MATERIAL AND METHODS: A survey of chiefs of emergency medicine service was performed in October-November 2005, in which 34 of the 59 institutions (58%) were participating. The questionnaire presented questions concerning physical and human resources, performance values, and system configuration. The study has shown that emergency medicine service operates in radius of 23 km, each team providing service for about 40,000 inhabitants. Taking into consideration distance and average on-scene time values, emergency medicine service is capable to render the first medical aid within so-called "golden hour" in case the accident is reported immediately. The physical resources are not quite complete. Not all the cars are equipped with essential first aid measures. Among more rarely found resources are vacuum pumps, intubation sets, defibrillators, vacuum splints, back immobilization devices, and hammock immobilization devices. There are less mentioned resources than working teams and even more than two times less than emergency cars at all. Two-thirds of the operating emergency medicine services do not provide advanced life support procedures. The evaluation of theoretical/practical ability to provide some important medical procedures used in emergency medical care showed that medical staff quite often fails to perform defibrillation, intubation, and pleural cavity drainage. CONCLUSIONS: Country ambulance service network configuration according to area under service, number of people served, and response frequency comply with the requirement set. The ambulance vehicles lack complete set up as well as some important supplies. Only rarely the staff is skilled enough to perform such advanced life support procedures as intubation, defibrillation, and pleural drainage.

[New guidelines for resuscitation in adults]. / Naujos suaugusiuju gaivinimo rekomendacijos.

Five years after the last issue of the guidelines for cardiopulmonary resuscitation and emergency cardiovascular care, in 2005 American Heart Association and European Resuscitation Council published new guidelines. In this review, basic life support (BLS) technique, indications for use of an automated external defibrillator (AED), recognition of sudden cardiac arrest, and management of choking (foreign-body airway obstruction) are presented according to the "Resuscitation Guidelines 2005."

Time Evolution of Sublingual Microcirculatory Changes in Recreational Marathon Runners.

We aimed to evaluate changes in sublingual microcirculation induced by a marathon race. Thirteen healthy male controls and 13 male marathon runners volunteered for the study. We performed sublingual microcirculation, using a Cytocam-IDF device (Braedius Medical, Huizen, Netherlands), and systemic hemodynamic measurements four times: 24 hours prior to their participation in the Kaunas Marathon (distance: 41.2 km), directly after finishing the marathon, 24 hours after the marathon, and one week after the marathon. The marathon runners exhibited a higher functional capillary density (FCD) and total vascular density of small vessels at the first visit compared with the controls. Overall, we did not find any changes in sublingual microcirculation of the marathon runners at any of the other visits. However, in a subgroup of marathon runners with a decreased FCD compared to the subgroup with increased FCD, the subgroup with decreased FCD had shorter running time (190.37 ± 30.2 versus 221.80 ± 23.4 min, p = 0.045), ingested less fluids (907 ± 615 versus 1950 ± 488 mL, p = 0.007) during the race, and lost much more weight (-2.4 ± 1.3 versus -1.0 ± 0.8 kg, p = 0.041). Recreational marathon running is not associated with an alteration of sublingual microcirculation. However, faster running and dehydration may be crucial for further impairing microcirculation.
