Abstract
Background: Central venous catheterization (CVC) is a common procedure associated with various side effects such as pneumothorax. Recently, the routine post-catheterization chest X-ray has been challenged. The aim of the present study was to design a scoring system for selecting patients requiring radiography after CVC procedure. Materials and Methods: In this cross-sectional study, 210 patients requiring CVC were enrolled in the study and pneumothorax potential risk factors, including body mass index>30, history of neck or chest surgery, emphysematous disease, history of catheterization, number of punctures, inappropriate position during CVC, and treatment with ventilator were recorded. Finally, chest radiography and clinical signs before and after CVC were compared and scoring system sensitivity and specificity were determined. Results: Incidence of pneumothorax was 5.24%. The number of punctures and patient's position and history of catheterization showed significant associations with pneumothorax development (p<0.001). Pneumothorax incidence in patients with score> 4 was 80% which was significantly higher than patients with score<4 (OR: 174.2, p<0.001). Sensitivity and specificity of using the scoring system at cut-off score> 2 were 81.8% and 87.9%, respectively. Conclusion: The results of this study showed that pneumothorax development risk is very low in patients with score<2 and there is no need for post CVC routine chest X-ray. However, in patients with score>4, pneumothorax development risk is high and it seems that chest radiography with close intervals even more than one time is necessary. Further studies are recommended to validate the proposed scoring system.

Abstract
Background and Aim This study aimed to investigate the demographic and clinical information of patients undergoing surgery with ultrasound in internal jugular vein cannulation.
Methods & Materials After the approval of the plan in the ethics committee of Guilan University of Medical Sciences, this study was performed in the general surgery department of Razi Hospital in 2018 on 100 patients in need of central venous catheter implantation. The neck type (distance between the two designated areas) was entered in a special form made by the researcher and after the completion of the design, it was examined and statistically analyzed.
Ethical Considerations This research ethically approved by the Ethics Committee of Guilan University of Medical Sciences (Code: IR.GUMS.REC.1396.20)
Results The mean age of the studied patients was 58.72±16.09 years. The anatomical and sonographic margins between the two Land Mark areas were higher in men VS women, but there was no statistically significant difference (P>0.05). However, there was no statistically significant difference between the other variables. (P>0.05).
Conclusion The findings of this study show that catheterization of the internal jugular vein under the guidance of ultrasound was less access time and fewer complications.
