ABSTRACT
Background: Central Venous Access (CVA) is acommon requirement in the critically ill patient for avariety of indications including Central VenousPressure (CVP) monitoring, haemodialysis, placementof pulmonary artery catheters, cardiac pacing and foradministration of drugs especially vasoactive,chemotherapy agents and parenteral nutrition.Traditionally, Central Venous Catheter (CVC)placement is performed using Landmark (LM)technique and is associated with complications likearterial puncture, pneumothorax, hemothorax, airembolism, catheter embolism, and cardiac arrhythmias.Use of Ultrasound (US) is currently indicated forvarious clinical situations to reduce complication rate ofLM technique. Aim and Objectives: The purpose of thisstudy was to determine whether US guidance couldimprove the success rate, number of attempts, and rateof acute complications like inadvertent arterialpuncture, hematoma formation, and pneumothorax ofsubclavian venous catheterization. Material andMethods: Sixty patients in need of central venouscatheter were prospectively randomized in two groupsof 30 each. In the LM group patients were catheterizedusing the LM method and in US group patients werecatheterized by real-time US-guidance. Number ofattempts, success rate, access time and complicationslike accidental subclavian artery puncture, haematomaformation, pneumothorax, were recorded. p values<0.05 were considered statistically significant. Results:In the US group 30 (100%) of patients were successfullycannulated with the US guidance while the landmarktechnique was successful in 26 (86.66%) of patients. Inthe US group the success on first attempt was 83.33 %which was a significantly higher from 56.67% achievedin the LM group (p=0.025). The average number ofattempts for successful cannulation in the US group was1.16 ± 0.4, while in the LM group it was 1.56 ± 0.9 withstatistically significant difference (p=0.046). Accesstime was 27.26 ± 04.62 seconds in the US group, whilethe access time was significantly more in the LM group36.56 ± 17.35 seconds (p=0.0062). Conclusion: USguidance during subclavian vein catheterizationincreases overall and first attempt success, improvesaccess time with reduced average number of attemptsand complications.
ABSTRACT
Central venous catheterization is an essential procedure in patient undergoing cardiac surgery, as it provides central venous pressure monitoring, fluid administration, and infusion of inotropes during perioperative period. In the cardiac surgery, where the patients are anticoagulated, an inadvertent arterial puncture can lead to serious complications. Hematoma following inadvertent arterial puncture is one of the common complications, which can compromise cerebral circulation. We report a rare case of inadvertent cannulation of internal carotid artery in patients of tetralogy of Fallot undergoing intracardiac repair during an attempt to cannulate internal jugular vein.
ABSTRACT
Introduction: Introducer needle tip is not clearly visible during the real‑time ultrasound (US)‑guided central vein cannulation (CVC). Blind tip leads to mechanical complications. This study was designed to evaluate whether real‑time US‑guided CVC with a marked introducer needle is superior to the existing unmarked needle. Methodology: Sixty‑two critically ill patients aged 18–60 years of either sex were included in the study. The patients were randomized into two groups based on whether a marked or unmarked introducer needle was used. Both groups underwent real‑time US‑guided CVC by a single experienced operator. Aseptically, introducer needle was indented with markings spaced 0.5 cm (single marking) and every 1 cm (double marking). This needle was used in the marked group. Approximate depths (centimeter) of the anterior and posterior wall of the internal jugular vein, anterior wall of the internal carotid artery, and lung pleura were appreciated from the midpoint of the probe in short‑axis view at the level of the cricoid cartilage. Access time (seconds) was recorded using a stopwatch. A number of attempts and complications such as arterial puncture, hematoma, and pneumothorax of either procedure were compared. Results: Both marked needle and unmarked needle groups were comparable with regard to age, gender, severity scores, platelet counts, prothrombin time, and distance from the midpoint of the probe to the vein, artery, and pleura and skin‑to‑guide wire insertion access time. However, an average number of attempts (P = 0.03) and complications such as hematoma were significantly lower (P = 0.02) with the marked introducer needle group. Pneumothorax was not reported in any of the groups. Conclusion: Our study supports the idea that marked introducer needle can further reduce the iatrogenic complications of US‑guided CVC.
ABSTRACT
Central venous cannulation is often associated with complications during insertion even by expert’s hand and with the aid of ultrasound. We encountered a patient for central line insertion through the right internal jugular vein having a retropharyngeal abscess of tubercular origin. We accidentally punctured the abscess cavity leading to increased respiratory distress and subsequent need of intubation to the patient. This kind of complication during central line insertion has never been reported before. We intend to report such a case to alert everyone about the grave complications it can lead to and the methods to minimize them in the times ahead.
ABSTRACT
<p><b>INTRODUCTION</b>We studied the effect of head rotation on the relative position of the right common carotid artery (CCA) and the right internal jugular vein (IJV) in patients with laryngeal mask airway (LMA) insertion to evaluate the accuracy of anatomical landmarks for right IJV cannulation.</p><p><b>METHODS</b>We simulated needle insertion to the right IJV on sonograms via the central landmark approach and an approach using the external jugular vein, in patients with LMA insertion (n = 50) or endotracheal intubation (E-tube, n = 50). Overlap index and successful simulation rates were measured according to the different degrees of head rotation.</p><p><b>RESULTS</b>The overlap index between the right CCA and the right IJV increased with greater degrees of head rotation. It was significantly greater in the LMA insertion group than in the E-tube group in the following head rotation positions: neutral, 15° and 45°. The success rate of the simulation was lower in the LMA insertion group than in the E-tube group. In the LMA insertion group, the success rate of the simulation was highest (62%) with the central landmark approach and in the 15° head rotation position.</p><p><b>CONCLUSION</b>In the LMA insertion group, the overlap index increased incrementally with greater head rotation degrees (from neutral to 45°). The central landmark approach and 15° head rotation position appear to be the optimal puncture site and degree of head rotation for right IJV cannulation in patients with LMA insertion.</p>

Background: Catheterization of Internal Jugular Vein (IJV) is commonly attempted to obtain central venous access for hemodynamic monitoring, long term administration of fluids, total parenteral nutrition and hemodialysis in critical care patients. The safe puncture of the IJV is achieved by using anatomical land marks on skin surface. Ultrasound guidance could be beneficial in placing central venous catheters by improving the success rate, reducing the number of needle passes, decreasing access time and decreasing complications. Material andMethods: Sixty critical care patientswere selected for IJV cannulation either by landmark technique or by ultrasound guided technique in two groups of thirty each. Results: In our study there was 100% success rate for first attempt cannulation in USG technique and where as it was 83.3% in LMG technique. The mean access time in USG technique was 152.50 ± 63.90 sec as against 323.23 ± 146.19 sec in LMG group. Conclusion: Ultrasound guided technique improves the cannulation of the IJV with respect to safety, rapidity and comfort to the patient during the procedure.
ABSTRACT
La cateterización venosa central de la vena subclavia que utiliza reparos anatómicos, es empleada rutinariamente en la unidad de cuidados intensivos. Sin embargo, la técnica guiada por ultrasonido en tiempo real, se ha convertido en una de las 10 prácticas más seguras que mejoran la calidad de la atención en los pacientes críticos. Todavía existe cierta incertidumbre al comparar ambos métodos. Se realizó una revisión de la literatura en las bases de datos PUBMED y EMBASE desde 1985 al 2013, con el objetivo de proveer estudios que utilicen la novedosa técnica de cateterización de la vena subclavia guiada por ultrasonido, así como recomendaciones de su utilización. Se encontraron un total de 102 artículos, tres metaanálisis y dos guías de cateterización venosa central por ultrasonido. El método guiado por ecografía es una técnica promisoria, con una creciente utilización en recién nacidos, niños y adultos. La mayoría de la evidencia demuestra mejores tasas de efectividad, así como disminución del número de complicaciones en comparación con la técnica de reparos anatómicos. Las recomendaciones actuales son las de utilizar el método estático y dinámico para la cateterización; se plantea que este último no debe ser realizado durante la emergencia.
Central venous catheterisation of the subclavian vein using anatomical repairs is routinely used in the intensive care unit. However, ultrasound-guided real-time technique has become one of the 10 safest practices that improve the quality of care in critically ill patients. There is still some uncertainty when comparing both methods. A review of the literature in PubMed and EMBASE databases was performed from 1985 to 2013, with the objective of providing studies using the novel technique of catheterisation of the subclavian vein under ultrasound guidance and recommending its use. A total of 102 articles, three meta-analyzes and two ultrasound-guided subclavian venous catheterisations were found. The ultrasound-guided method is a promising technique, with an increasing use in newborns, children, and adults. Most evidence shows better success rates and fewer complications compared with the technique of anatomical repairs. Current recommendations are to use static and dynamic method for catheterisation; it is argued that the latter should not be performed during the emergency.

OBJECTIVES: To compare the landmark-guided technique versus the ultrasound-guided technique for internal jugular vein cannulation in spontaneously breathing patients. METHODS: A total of 380 patients who required internal jugular vein cannulation were randomly assigned to receive internal jugular vein cannulation using either the landmark- or ultrasound-guided technique in Bursa, Uludag University Faculty of Medicine, between April and November, 2008. Failed catheter placement, risk of complications from placement, risk of failure on first attempt at placement, number of attempts until successful catheterization, time to successful catheterization and the demographics of each patient were recorded. RESULTS: The overall complication rate was higher in the landmark group than in the ultrasound-guided group (p < 0.01). Carotid puncture rate and hematoma were more frequent in the landmark group than in the ultrasound-guided group (p < 0.05). The number of attempts for successful placement was significantly higher in the landmark group than in the ultrasound-guided group, which was accompanied by a significantly increased access time observed in the landmark group (p < 0.05 and p < 0.01, respectively). Although there were a higher number of attempts, longer access time, and a more frequent complication rate in the landmark group, the success rate was found to be comparable between the two groups. CONCLUSION: 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 immediate complications.

Ultrasound-guided catheterization of the central vein is a precise, safe, and easy compared with the conventional landmark method. We incidentally detected thrombosis in the right internal jugular vein (IJV) during the ultrasound-guided cannulation (on) in a 22-month-old male patient. Cardiac operations had been performed 5 times previously and the right IJV was cannulated lastly 2 months ago. The thrombosis occluded right IJV near totally, so we cannulated the left IJV instead using the ultrasound. This case demonstrates that ultrasound-guided central vein catheterization approach is helpful not only in precise puncture but also in selection of appropriate vessel.

Wolff-Parkinson-White (WPW) syndrome is a cardiac conduction disorder that presents potentially life-threatening consequences, and it is important that anesthesiologists recognize this syndrome because the sudden development of tachyarrhythmias may result in deleterious hemodynamic changes. We report an episode of severe hemodynamic changes induced by the insertion of a guide wire during central venous cannulation and operation in a 62-yr-old female patient with WPW syndrome. Initially, unstable paroxysmal supraventricular tachycardia was developed during central venous cannulation, which was disappeared immediately upon removing the guide wire. Subsequently, paroxysmal supraventricular tachycardia with severe hemodynamic changes developed 2 hours after operation, and this was successfully treated with an intravenous injection of adenosine, deep anesthesia with sevoflurane and fentanyl, and dopamine infusion. The patient recovered uneventfully after the operation.

Central venous cannulation via an internal jugular vein has become a common procedure in the management and monitoring of severely ill patients. Although complications such as carotid artery puncture or pneumothorax have been reported, hemothorax is relatively uncommon. We describe a case of hydrohemothorax and subclavian artery laceration which occurred during right internal jugular vein cannulation. A 44-year-old female patient was admitted for laparoscopic adrenalectomy under general anesthesia. For central venous pressure monitoring, central venous cannulation performed. However, dilator overinsertion injured the right subclavian artery. This led to a massive ipsilateral hydrohemothorax requiring thoracotomy for subclavian artery repair. This case suggests that central venous cannulation should be done carefully and improves awareness of the potential for dilator induced injury.

BACKGOUND: This study was designed to evaluate the effectiveness and feasibility of central venous catheterization via the external jugular vein (EJV). We compared the success rate of left and right EJV catheterization. The influence of the course of left and right external jugular vein on success rate was investigated also. METHODS: Eighty anesthetized adult surgical patients were studied consecutively. Patients were allocated to left or right EJV catheterization and measured the angles between EJV and clavicle and transverse shoulder line. Catheterization was performed under sterile conditions by Seldinger technique after angiography of EJV and subclavian vein. We analyzed the relationship between the angles and success rate and time for catheterization. We compared the success rate of left and right EJV catheterization. RESULTS: The overall rate of intrathoracic placement was 74 from 80 catheterization (92.5%). Analysis of success in left and right EJV catheterization did not reveal statistically significant differences. The success rates did not show any correlation with course of EJV. Complications were few and not serious. CONCLUSIONS: This study indicated that left and right EJVs were good routes for central venous catheterizationan with acceptably high success rate. However, we could not find the predictor of success for central venous catheterization via EJV.
