Little is known about the long-term health and mental health status of women Vietnam veterans. For many of these women, the effects of this war are still present in their daily lives. As these women approach their mid-sixties, it is important to understand the impact of wartime deployment on health and mental health outcomes nearly 40 years later. The investigators propose to assess the prevalence of posttraumatic stress disorder (PTSD) and other mental and physical health conditions for women Vietnam veterans, and to explore the relationship between PTSD and other conditions and the Vietnam deployment experience. The investigators are interested in studying women Vietnam veterans who may have had direct exposure to traumatic events. For the first time, the investigators also want to study those who served in facilities near Vietnam. These women may have had similar, but less direct exposures. This cross-sectional study will seek to contact approximately 10,000 women for participation in a mailed survey, telephone interview and a review of their medical records. Women identified as serving in Vietnam, near Vietnam (in Asia during the Vietnam Ware) and in the U.S. during the Vietnam War will be identified from an established cohort and sent a survey on demographics, behaviors, disability, health-related quality of life, and medical conditions. Women agreeing to be contacted will also be interviewed by study investigators using the modified CIDI to ascertain current and lifetime mental health conditions (including PTSD) and exposure to traumatic events. A more extensive chart review will be conducted by a clinician to validate self-report of key medical conditions.

Patients were randomly divided into two groups: ultrasound-guided (US-guided) in-plane infraclavicular subclavian vein (IP-ISV) and in-plane supraclavicular subclavian vein (IP-SSV) catheterization. For IP-ISV cannulation, a linear transducer is placed in the infraclavicular fossa. After obtaining a long-axis view of the axillary vein and distal subclavian vein ,the needle is inserted in the midpoint of the small footprint transducer. Then,the needle is advanced under real-time US guidance until visualizing the tip of the needle inside the vein while noticing the lung pleura underneath the vessels. For IP-SSV cannulation, a short-axis view of the IJV is obtained first. The probe is slid caudally following the IJV until getting the best long-axis view of the SCV. Using an in-plane approach, the needle is inserted at the base of the transducer at a 30° angle and advanced under the long axis under real-time US guidance targeting the SCV.
