Abstract
Background: The central veins’ catheterization, required in critically ill patients, is more successful in larger veins. Some researchers hypothesized that hand preference might be associated with larger ipsi/contra central veins. 
Objective: To determine the diameter and depth of internal jugular and subclavian veins on both sides and its association with left- or right-handedness.
Methods: This cross-sectional study, was conducted on patients referring for elective breast or thyroid check-up to Shahid Faghihi Hospital ultrasound unit, Shiraz, Iran, from September 2014 to May 2015. Inclusion criteria consisted of adult normotensive patients with American Society of Anesthesiology (ASA) class I without underlying diseases. The patients’ demographics were recorded and the diameter and depth of the internal jugular and subclavian veins were measured by ultrasound. The results of measurements were compared between patients’ hand preference by SPSS version 19, using paired-samples t-test and independent-samples t-test.
Results: Of 65 patients, 86% were women and 19 were left-handed (29%) with the only significant difference between the right and left subclavian diameter in right-handed individuals (p=0.007) and no significant difference between the left and right internal jugular vein diameter and depth and subclavian vein depth between the left- and right-handed patients. The subclavian diameter of the right and left side was also not different in left-handed patients. 
Conclusion: The right or left central veins are not superior to each other with respect to diameter and depth in right- or left-handed patients.

Volume 12, issue 1, January-March 2020


Next Editorial:

In April-June 2020 issue, the journal will publish an editorial from Morocco (Dr. Benksim, Higher Institute of Nursing Professions and Health Techniques, Morocco). The editorial talks about lessons from COVID-19 pandemic and the Morocco’s success story. The April-June issue is expected to be published by end of June 2020.


 

The worldwide spread of COVID-19 as an emerging, rapidly evolving situation, and the dramatic need of urgent medicine or vaccine, has rapidly brought new hypotheses for pathophysiology and potential medicinal agents to the fore. It is crucial that the research community provide a way to publish this research in a timely manner.

To contribute to this important public health discussion, the Electronic Physician Journal is excited to announce a fast-track procedure to help researchers publish their articles on COVID-19 related subjects that fall under the broad definition of public health, internal medicine, and pharmacology. We are especially welcome to all hypotheses about the pathological basis of the COVID-19 infection and the possible characteristics of potential medicine and vaccine. Submit your manuscript here


 

The 6th World Conference on Research Integrity (WCRI) is to be held on June 2-5, 2019 in Hong Kong.

The WCRI is the largest and most significant international conference on research integrity. Since the first conference in Lisbon in 2007, it has given researchers, teachers, funding agencies, government officials, journal editors, senior administrators, and research students opportunities to share experiences and to discuss and promote integrity in research. Read more:
