Are all helicopter dispatches really necessary? a cross-sectional study.

Background: Pre-hospital emergency care is a critical part of the health care system. Helicopter emergency medical service (HEMS) is a novel part of the medical services of the health care delivery system. The goal of these medical services is to provide appropriate treatments at the right place and time.

A retrospective study on evaluating GAP, MGAP, RTS and ISS trauma scoring system for the prediction of mortality among multiple trauma patients.

Objectives: Predicting the outcome of trauma helps clinician to prioritize patients and provide timely and effective treatment. Several scoring systems are implemented to predict prognosis and mortality among these patients. Our study aims to use four scoring systems to predict mortality among multiple trauma patients.

Airway Management: Difficulty of Intubation and Range of Movement of the Thyroid Cartilage.

Purpose: Difficult endotracheal intubation has been associated with a number of anatomic factors. According to our experience, the range of movement of thyroid cartilage can be used as a useful test to determine the difficulty in endotracheal intubation. The aim of this study was to evaluate the association between the range of movement of thyroid cartilage and difficulty in intubation.

Invasive mechanical ventilation and clinical parameters in COVID19 patient: Can age be a factor?

Background: Severity of corona virus disease 2019 (COVID19) is presented with respiratory distress and requires mechanical ventilation. Advanced age is one of the significant risk factors of the worst prognosis and mortality in this disease. The aim of this study is to investigate the clinical parameter among COVID19 patients under mechanical ventilation in regard to the age groups.

Evaluating characteristics associated with the mortality among invasive ventilation COIVD -19 patients.

Background: Coronavirus disease 2019 (COVID-19) is associated acute respiratory distress syndrome that leads to intensive care unit admission and subsequent need of invasive ventilation. The aim of this study is to evaluate mortality rate and associated parameters among COVID 19 patients under invasive ventilation.

Methods: In this retrospective studies, COVID 19 patients referred to our center we evaluated.

Pulmonary thromboembolism with transthoracic ultrasound and computed tomography angiography.

Objective: The detection of pulmonary embolism in emergency department requires an urgent therapeutic and diagnostic attention. This study was performed to determine the accuracy and efficacy of ultrasound in the diagnosis of pulmonary embolism.

Methods: In this study, 110 patients who referred to the emergency department with traumatic embolism symptoms were enrolled.

Evaluation of invasive ventilation (intubation) prognosis in patients with Covid-19 symptoms.

Background: Coronavirus 2019 (COVID 19) has been reported as a pandemic by the world health organization. Increasing number of cases and associated mortality have demanded the need for clinical studies and researches.

Objective: The aim of this study is to evaluate intubation prognosis of the COVID 19 patients referred to Shahid Beheshti hospital in Qom city.
