Randomized Controlled Trial Comparative StudyComparison of an ultrasound-guided technique versus a landmark-guided technique for internal jugular vein cannulation.
Central venous cannulation is a commonly preformed procedure in many branches of medicine, particularly in anaesthesia and intensive care medicine. The purpose of this study was to compare the landmark-guided technique to the ultrasound-guided technique for internal jugular vein cannulation in cardiovascular surgery patients. One hundred cardiovascular surgery patients, of whom 65 were male and 35 were female with ages ranging from 22 to 65, who had internal jugular cannulation between December 2010-March 2011 in our clinic were investigated prospectively. ⋯ Four patients had an arterial punction [group U (n=0) and group A (n=4)] and two patients had a hematoma [group U (n=1) and group A (n=1)]. Arterial punction complication was increased significantly in landmark group (p=0.041). The findings of this study indicate that internal jugular vein catheterization guided by real-time ultrasound results in a lower access time and a lower rate of attempts.

Real-time two-dimensional and three-dimensional echocardiographic imaging of the thoracic spinal cord: a possible new window into the central neuraxis.
Transesophageal echocardiography of the spine has been difficult to perform, and high-quality images have been difficult to obtain with earlier available technology. New capabilities in hardware and software reconstruction may allow more reliable clinical data to be obtained. We describe an initial successful attempt to image the adult spinal canal, its contents, and in situ instrumentation. ⋯ Pulsed-wave Doppler determined a biphasic pattern of blood flow in the anterior spinal artery through pulse mapping of the anatomic area. New, advanced imaging hardware and software generate clinically useful imaging of the thoracic spine in 2-D and 3-D using TEE. We believe this technology holds promise for future diagnostic and therapeutic interventions in the operating room that were previously unavailable.

Observational StudyThe use of a clinical database in an anesthesia unit: focus on its limits.
Anesthesia information management system (AIMS) can be used a part of quality assurance program to improve patient care, however erroneous or missing data entries may lead to misinterpretation. This study assesses the accuracy of information extracted for six consecutive years from a database linked to an automatic anesthesia record-keeping system. An observational study was conducted on a database linked AIMS system. ⋯ However exhaustivity/completeness of some other variable, such as nausea and vomiting started as low as 50% to reach 20% at 2008. After cross analysing pain and post-operative nausea and vomiting scores with related medication consumption, (morphine and ondansetron) we conclude that missing data was due to omission of a zero score rather than human error. The follow-up of quality assurance program may use data from AIMS provided that missing or erroneous values be mentioned and their impact on calculations accurately analysed.
