A Descriptive Comparison of Ultrasound-guided Central Venous Cannulation of the Internal Jugular Vein to Landmark-based Subclavian Vein Cannulation

ACADEMIC EMERGENCY MEDICINE, Issue 4 2010
Daniel Theodoro MD
Abstract Objectives:, The safest site for central venous cannulation (CVC) remains debated. Many emergency physicians (EPs) advocate the ultrasound-guided internal jugular (USIJ) approach because of data supporting its efficiency. However, a number of physicians prefer, and are most comfortable with, the subclavian (SC) vein approach. The purpose of this study was to describe adverse event rates among operators using the USIJ approach, and the landmark SC vein approach without US. Methods:, This was a prospective observational trial of patients undergoing CVC of the SC or internal jugular veins in the emergency department (ED). Physicians performing the procedures did not undergo standardized training in either technique. The primary outcome was a composite of adverse events defined as hematoma, arterial cannulation, pneumothorax, and failure to cannulate. Physicians recorded the anatomical site of cannulation, US assistance, indications, and acute complications. Variables of interest were collected from the pharmacy and ED record. Physician experience was based on a self-reported survey. The authors followed outcomes of central line insertion until device removal or patient discharge. Results:, Physicians attempted 236 USIJ and 132 SC cannulations on 333 patients. The overall adverse event rate was 22% with failure to cannulate being the most common. Adverse events occurred in 19% of USIJ attempts, compared to 29% of non,US-guided SC attempts. Among highly experienced operators, CVCs placed at the SC site resulted in more adverse events than those performed using USIJ (relative risk [RR] = 1.89, 95% confidence interval [CI] = 1.05 to 3.39). Conclusions:, While limited by observational design, our results suggest that the USIJ technique may result in fewer adverse events compared to the landmark SC approach.

Right Axillary Vein Cannulation for Percutaneous Cardiopulmonary Support

ARTIFICIAL ORGANS, Issue 2 2007
Masato Tochii
Abstract:, A 34-year-old male with a past history of permanent inferior vena cava (IVC) filter placement was referred to us for chronic thromboembolic pulmonary hypertension. Percutaneous cardiopulmonary support (PCPS) was required for the lung hemorrhage and reperfusion injury, although the thromboendarterectomy was successfully completed. The arterial cannula was inserted into the femoral artery, and the venous cannula was inserted into the right axillary vein. The patient was weaned from PCPS 1 day after the operation and was discharged 35 days after the operation. Axillary vein cannulation is thought to be a feasible method when PCPS is required for a patient with previous IVC filter placement. [source]

An outcome study on complications using routine ultrasound assistance for internal jugular vein cannulation

ACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 10 2007
M. Lamperti
Background:, Ultrasound guidance for central venous cannulation is advised by recent guidelines, but is not being applied in everyday practice. The purpose of this study was to determine the reduction in complications when applying an ultrasound locating device for internal jugular vein catheterization. Methods:, An observational study was conducted from November 2004 to October 2005 in a tertiary neurosurgical hospital on 300 patients undergoing internal jugular vein cannulation using an ultrasound technique. Patients were not randomized and operators were trained using theoretical and practical courses. Prior to the study, the investigators, who were consultant anaesthesiologists, had to perform at least 20 successful supervised cannulations. Results:, Cannulation was successful in all cases. The incidence of arterial puncture was 2.7%, and multiple venous punctures represented the main minor complication (14%). Bivariate analysis of the overall complications revealed no significant correlation with age group, American Society of Anesthesiologists' (ASA) classification, body mass index, or position and diameter of the vein. Conclusions:, Ultrasound cannulation of the internal jugular vein minimized complications. These could be avoided when new ultrasound probes and specific needles are introduced. [source]

ORIGINAL ARTICLE: Ultrasonographic evaluation of the femoral vein in anaesthetised infants and young children

ANAESTHESIA, Issue 9 2010
E. H. Suk
Summary We investigated the cross-sectional area of the femoral vein and its relationship to the femoral artery at two anatomical levels, in infants and children. Sixty-six subjects were allocated to one of two groups: infants (< 1 year, n = 31) or children (1,6 years, n = 35). After induction of general anaesthesia, the femoral vein was evaluated by ultrasound with the patients' legs at 30° and 60° of abduction and their hips externally rotated. In each position, measurements were taken at the level of the inguinal crease and 1 cm below the crease. Hip rotation with 60° leg abduction decreased femoral artery overlap at the level of the inguinal crease in both infants (p = 0.013) and children (p = 0.003). Thus, the optimal place for femoral vein cannulation in paediatric patients seems to be at the level of the inguinal crease with 60° leg abduction and external hip rotation. [source]

Effects of head rotation on the right internal jugular vein in infants and young children

ANAESTHESIA, Issue 3 2010
M. J. Gwak
Summary We investigated the effects of head rotation on the cross-sectional area of the right internal jugular vein and its relative position to the carotid artery. Eighty-eight subjects were divided into infants and children groups. The cross-sectional area of the right internal jugular vein and the degree of the carotid artery overlap were measured at 0° (neutral), 40° and 80° of head rotation. The cross-sectional area of the right internal jugular vein was significantly larger at 40° and 80° head rotation compared with the neutral position in both infants and children (p < 0.001). As the head was rotated, the percentage overlap of the carotid artery increased significantly (p < 0.001). We suggest that 40° head rotation appears to be optimal for right internal jugular vein cannulation in paediatric patients. [source]
