DIAGNOSIS OF PULMONARY EMBOLISM IN THE EMERGENCY DEPARTMENT.

The aim of this study was to determine the association of clinical presentation, the Wells scoring system and D-dimer values with MSCT pulmonary angiography. A case control study was conducted in the Emergency Department of the Clinical Hospital Sveti Duh throughout 2019. Patients with a referral diagnosis of a pulmonary embolism were included in the study. Patients were divided into two groups. The first group consisted of patients diagnosed with pulmonary embolism by MSCT pulmonary angiography or postmortem, and the second group consisted of patients excluded from pulmonary embolisms. For the Wells score, D-dimers, troponin, respiratory rate and peripheral blood oxygen saturation, statistically significant differences were found between groups of patients with confirmed or excluded pulmonary embolism (p <0.001). For heart rate, chest pain, syncope, and hemoptysis, no statistically significant differences were found between these two groups of patients. Deep venous thrombosis of the lower extremities was found by ultrasound in > 70% of patients with massive a pulmonary embolism. Pulmonary embolism was confirmed in all patients for whom a high risk was calculated according to the Wells score. In conclusion, a low degree of clinical probability (according to the Wells score), along with a normal concentration of D-dimer, are a sure strategy in excluding pulmonary embolism.

DIAGNOSTIC VALUE OF CARDIAC ULTRASOUND IN ESTIMATING THE DURATION OF ARTERIAL HYPERTENSION.

The aim of the study was to assess the correlation between the degree and duration of arterial hypertension and the hypertrophy of the left ventricle and the ejection fraction of the heart, with cardiac ultrasound. Our prospective study included 50 patients with arterial hypertension as leading diagnosis. All 50 patients were consecutively examined in the Emergency Department and then referred to the Cardiac clinic of the Clinical Hospital "Sveti Duh" for further evaluation. The inclusion criteria were male and female aged 18 and older and arterial hypertension as leading diagnosis during Emergency Department visit. Exclusion criteria were pathological conditions that alter myocardial architecture and impair contractility. Measurement of the left ventricle thickness based on the thickness of the intraventricular septum and the posterior wall of the left ventricle, and the ejection fraction was ultrasonically determined. The highest proportion of subjects was with the first degree of arterial hypertension, followed by subjects with a third degree. The average duration of arterial hypertension was 6.14 years. Of the total number of subjects, 28% did not take any antihypertensive drugs. A statistically significant association was found between the degree and duration of arterial hypertension with the development of left ventricular hypertrophy. Significant association wasn't found between the degree or duration of arterial hypertension and the heart ejection fraction. Our study have shown strong correlation between the degree and duration of arterial hypertension and the development of left ventricular hypertrophy and ultrasound could be a useful method in the evaluation of some patients with arterial hypertension in the emergency department.

PERIPHERAL NERVE BLOCKS FOR HIP FRACTURES IN EMERGENCY MEDICINE.

Hip fractures represent a major public health issue with increasing incidence as a population ages. The aim of this review is to describe peripheral nerve block techniques (the fascia iliaca compartment block and the pericapsular nerve group block) as pain management for hip fractures in emergency medicine, and to emphasize their benefits. Hip fractures are extremely painful injuries. The pain itself is unpleasant for patients and if left untreated it can lead to multiple complications during preoperative, operative and postoperative patient management. Pain management for elderly hip fracture patients is often challenging. Non-steroidal anti-inflammatory drugs are not recommended due to their side effects, the increased risk of gastrointestinal bleeding, renal function impairment and platelet aggregation inhibition. Paracetamol alone is often insufficient, and opioids have many potentially harmful side effects, such as delirium development. Peripheral nerve blocks for hip fractures are safe and effective, also in emergency medicine settings. The benefits for patients are greater pain relief, especially during movement, less opioid requirements and decreased incidence of delirium. Regional analgesia should be routinely used in hip fracture pain management.
