Background & objectives: Trauma is one of the most common causes of death in  the age range 1 to 44 and the third cause of death regardless of age. Abdominal trauma is one of the most common types of trauma. This study aimed to investigate the frequency of causes of laparotomy in penetrating and blunt abdominal traumas in 2016.
Methods: This descriptive study was conducted on 120 medical records of patients hospitalized for penetrating and blunt abdominal traumas in Fatemi Hospital, Ardabil, 2016. The inclusion criterion consisted of all patients undergoing laparotomy due to abdominal trauma. In this study, age, gender, education level, type of trauma (blunt or penetrating), results of laparotomy surgery, physical examination and paraclinical findings of patients before operation were collected by a researcher- made checklist.
Results: The results showed that 80% of the patients were male and 35% were in the age range 20-29years. Of patients, 38.3% had penetrating trauma and 61.7% blunt trauma. The most common mechanism of blunt abdominal trauma was car accident (83.8%). Penetrating object was the cause of all penetrating abdominal traumas. Peritoneal stimulation symptoms were observed in 56.5% of penetrating abdominal traumas and 62.2% of blunt abdominal traumas. Hypotension was observed in 21.7% of patients with penetrating abdominal trauma compared with 62.2% in patients with blunt abdominal trauma. The most prevalent damaged organ in patients with blunt trauma was spleen (51.4%). The most prevalent damaged intraabdominal organ was small bowel (17.4%). Negative laparotomy was significantly higher in patients with penetrating trauma than those with blunt trauma (p<0.0001). Moreover, 9.2% of all patients had died and mortality rate was higher in patients with blunt trauma than penetrating trauma (p<0.05) .
Conclusion: The results of this study showed that: 1. Road traffic accident and penetrating object were the most common causes of laparotomy in patients with blunt and penetrating trauma respectively; 2. Spleen and small bowel were the most prevalent damaged organs in blunt and penetrating abdominal trauma respectively and; 3. Young males were at highest risk of abdominal traumas.

Background & objectives: The main motivator of hospitals is manpower. The expansion and complexity of educational medical centers and the appearance of new diseases such as Covid-19 have increased the need for effective management. During the Covid-19 crisis, in which hospitals are at the forefront, special measures should be taken for better management in critical situations. The current study has been conducted with the aim of identifying the main factors affecting management in crisis and its control.
Methods: The study method was the "Mix Method" performed in two stages. The first stage was exploratory; in this stage 19 university experts as a research sample were selected by simple random sampling. The second stage was a quantitative, confirmative, and survey study. 202 patients were selected randomly as a research sample from both educational-medical centers involved in Covid-19 of Ardabil city. Data were collected by using a questionnaire. Descriptive analysis of data was performed using SPSS software for heuristic factor analysis, and LISREL software was also used for confirmatory factor analysis and finding correlations between factors.
Results: In this study, 17 factors were identified and confirmed, affecting the crisis management in 5 dimensions, including; safety training, crisis control, trust in human resources, sense of vulnerability, the physical and mental health, transparency, justice, participation in decision-making, trust in the manager, honesty, the expectation of needs, efficiency, reward, elimination of stresses, fulfillment of manager's promises, controlling of crisis, inter-sectorial solidity. There was a significant correlation between factors with latent variables.
Conclusion: From the perspective of management, being prepared and training the committed forces are very important in controlling the crisis. Manpower plays the main role in the Covid-19 crisis and treating patients, so paying attention to them by considering the factors and dimensions of leadership, social, motivation, organization, and quickness has high importance.
