Unconventional Warfare Medicine Is the Ultimate Prolonged Field Care.

While conventional military forces have long been the focus of modern warfare, unconventional warfare (UW) will be waged behind enemy lines by US, allied, partner special operations forces (SOF), and civilian resistance movements. Prolonged field care (PFC) will be a forced necessity in the UW environment with unique challenges to mobility and security. Recorded experiences from World War II of allied surgeons and others reveal insights about how to prepare for this unique set of special warfare in the future, including in the areas of manning, training, planning, operations, and equipping. Countries at potential seams of conflict, like the Baltic States, possess significant UW experience. Lithuanian SOF medical leaders have developed a guerilla medicine course that increases readiness to provide PFC and austere resuscitative surgical care in UW. US military medical forces can benefit from partners like Lithuania and others by sharing knowledge, experiences, and adapting best practices to our tactics, techniques, and procedures.

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.

Evaluation of volume status in a prehospital setting by ultrasonographic measurement of inferior vena cava and aorta diameters.

OBJECTIVES: The aim of this study was to evaluate the utility of ultrasonographic measurement of the diameter of the inferior vena cava (IVCD) and abdominal aorta (AAD) for assessing volume status. MATERIAL AND METHODS: This was a prospective, observational study. A total of 23 volunteers participated in the study. Each participant was selected randomly. All participants completed the 2016 Kaunas Marathon. Participants filed out a brief survey about their fluid intake (in standardised glasses) in the 24 h before the race and during the race. Participants underwent ultrasound measurements 10-40 min before the start of the race and 3-15 min after finishing the race. To visualize respiratory variation, M-mode was used, with the beam crossing the IVCD 2 cm from the right atrium. The AAD was measured 1 cm above the celiac trunk. IVCD in expiration (IVCDexp)/AAD was calculated by dividing the value of IVCDexp by the value of AAD. The findings were compared with difference in body mass index. RESULTS: The mean weight lost after the marathon was 2.93 kg (p < 0.001). Mean IVCD in inspiration (IVCDins) after the run was lower by 0.39 cm (p < 0.001) then before the run. Mean IVCDexp/AAD after the run was 0.24 cm lower than before the run (p = 0.03). Before and after the marathon, there was a statistically significant negative correlation in weight difference, with mean IVCDexp difference (p = 0.047). There was no statistically significant difference in caval index before and after running. CONCLUSION: Ultrasonographic assessment of IVCDexp could be useful in the evaluation of volume status.

Factors influencing the suicide intervention skills of emergency medical services providers.

BACKGROUND: Lithuania currently has the highest suicide rate in Europe and the fifth highest worldwide. AIMS: To identify the factors that influence the suicide intervention skills of emergency medical services (EMS) providers (doctors, nurses, paramedics). METHOD: Two hundred and sixty-eight EMS providers participated in the research. The EMS providers were surveyed both prior to their training in suicide intervention and six months later. The questionnaire used for the survey assessed their socio-demographic characteristics, suicide intervention skills, attitudes towards suicide prevention, general mental health, strategies for coping with stress, and likelihood of burnout. RESULTS: Better suicide intervention skills were more prevalent among EMS providers with a higher level of education, heavier workload, more positive attitudes towards suicide prevention, better methods of coping with stress, and those of a younger age. Six months after the non-continuous training in suicide intervention, the providers' ability to assess suicide risk factors had improved, although there was no change in their suicide intervention skills. CONCLUSIONS: In order to improve the suicide intervention skills of EMS providers, particular attention should be paid to attitudes towards suicide prevention, skills for coping with stress, and continuous training in suicide intervention. ABBREVIATIONS: EMS: Emergency medical services; SIRI: Suicide intervention response inventory.

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.

Magical manoeuvre: a 5-s instructor's intervention helps lightweight female rescuers achieve the required chest compression depth.

BACKGROUND: Adequate chest compression (CC) depth is crucial for resuscitation outcomes. Lightweight rescuers, particularly women, are often unable to achieve the required 5-6 cm CC depth. This nonrandomized cohort study investigated new strategies to improve CC performance. OBJECTIVE: To evaluate the effects of a 5-s instructor's intervention on the depth of CCs performed by female rescuers during standard video self-instruction basic life support training. METHODS: Data were prospectively collected from January 2011 to January 2012 from 336 female medical and pharmacy students undergoing cardiopulmonary resuscitation (CPR) training at the Lithuanian University of Health Sciences. During the training process, the instructors performed a simple 5-s intervention (Andrew's manoeuvre) with all of the rescuers in the study group. The instructor pushed 10 times on the shoulders of each trainee while she performed CCs to achieve the maximal required compression depth. Immediately after training, the participants were asked to perform a 6-min basic life support test on a manikin that was connected to a PC with Skill Reporter System software; the quality of the participants' CPR skills was then evaluated. RESULTS: The CC depth in the study group increased by 6.4 mm (P<0.001) compared with the control group (52.9 vs. 46.6 mm). A regression analysis showed that Andrew's manoeuvre increased the depth of the CCs among women by 14.87×(1-0.01×weight) mm. CONCLUSION: A simple 5-s instructor's intervention during the CPR training significantly improved the performance of the female rescuers and helped them achieve the CC depth required by 2010 resuscitation guidelines. Andrew's manoeuvre is most effective among the women with the lowest body weight.

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.

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.
