Best choice of central venous insertion site for the prevention of catheter-related complications in adult patients who need cancer therapy: a randomized trial. Femoral vs jugular venous catheterization and risk of nosocomial events in adults requiring acute renal replacement therapy: a randomized controlled trial. Complications of femoral and subclavian venous catheterization in critically ill patients: a randomized controlled trial.
Central venous access is extensively used in oncology, though practical information from randomized trials on the most convenient insertion modality and site is unavailable.
                Four hundred and three patients eligible for receiving i.v. chemotherapy for solid tumors were randomly assigned to implantation of a single type of port (Bard Port, Bard Inc., Salt Lake City, UT), through a percutaneous landmark access to the internal jugular, a ultrasound (US)-guided access to the subclavian or a surgical cut-down access through the cephalic vein at the deltoid-pectoralis groove. Early and late complications were prospectively recorded until removal of the device, patient's death or ending of the study.
                Four hundred and one patients (99.9%) were assessable: 132 with the internal jugular, 136 with the subclavian and 133 with the cephalic vein access. The median follow-up was 356.5 days (range 0-1087). No differences were found for early complication rate in the three groups {internal jugular: 0% [95% confidence interval (CI) 0.0% to 2.7%], subclavian: 0% (95% CI 0.0% to 2.7%), cephalic: 1.5% (95% CI 0.1% to 5.3%)}. US-guided subclavian insertion site had significantly lower failures (e.g. failed attempts to place the catheter in agreement with the original arm of randomization, P = 0.001). Infections occurred in one, three and one patients (internal jugular, subclavian and cephalic access, respectively, P = 0.464), whereas venous thrombosis was observed in 15, 8 and 11 patients (P = 0.272).
                Central venous insertion modality and sites had no impact on either early or late complication rates, but US-guided subclavian insertion showed the lowest proportion of failures. Based on concerns about the risk of infection, the jugular site is often preferred over the femoral site for short-term dialysis vascular access.
                To determine whether jugular catheterization decreases the risk of nosocomial complications compared with femoral catheterization.
                A concealed, randomized, multicenter, evaluator-blinded, parallel-group trial (the Cathedia Study) of 750 patients from a network of 9 tertiary care university medical centers and 3 general hospitals in France conducted between May 2004 and May 2007. The severely ill, bed-bound adults had a body mass index (BMI) of less than 45 and required a first catheter insertion for renal replacement therapy.
                Patients were randomized to receive jugular or femoral vein catheterization by operators experienced in placement at both sites.
                Rates of infectious complications, defined as catheter colonization on removal (primary end point), and catheter-related bloodstream infection.
                Patient and catheter characteristics, including duration of catheterization, were similar in both groups. More hematomas occurred in the jugular group than in the femoral group (13/366 patients [3.6%] vs 4/370 patients [1.1%], respectively; P = .03). The risk of catheter colonization at removal did not differ significantly between the femoral and jugular groups (incidence of 40.8 vs 35.7 per 1000 catheter-days; hazard ratio [HR], 0.85; 95% confidence interval [CI], 0.62-1.16; P = .31). A prespecified subgroup analysis demonstrated significant qualitative heterogeneity by BMI (P for the interaction term < .001). Jugular catheterization significantly increased incidence of catheter colonization vs femoral catheterization (45.4 vs 23.7 per 1000 catheter-days; HR, 2.10; 95% CI, 1.13-3.91; P = .017) in the lowest tercile (BMI <24.2), whereas jugular catheterization significantly decreased this incidence (24.5 vs 50.9 per 1000 catheter-days; HR, 0.40; 95% CI, 0.23-0.69; P < .001) in the highest tercile (BMI >28.4). The rate of catheter-related bloodstream infection was similar in both groups (2.3 vs 1.5 per 1000 catheter-days, respectively; P = .42).
                Jugular venous catheterization access does not appear to reduce the risk of infection compared with femoral access, except among adults with a high BMI, and may have a higher risk of hematoma.
                clinicaltrials.gov Identifier: NCT00277888. Whether venous catheterization at the femoral site is associated with an increased risk of complications compared with that at the subclavian site is debated.
                To compare mechanical, infectious, and thrombotic complications of femoral and subclavian venous catheterization.
                Concealed, randomized controlled clinical trial conducted between December 1997 and July 2000 at 8 intensive care units (ICUs) in France.
                Two hundred eighty-nine adult patients receiving a first central venous catheter.
                Patients were randomly assigned to undergo central venous catheterization at the femoral site (n = 145) or subclavian site (n = 144).
                Rate and severity of mechanical, infectious, and thrombotic complications, compared by catheterization site in 289, 270, and 223 patients, respectively.
                Femoral catheterization was associated with a higher incidence rate of overall infectious complications (19.8% vs 4.5%; P<.001; incidence density of 20 vs 3.7 per 1000 catheter-days) and of major infectious complications (clinical sepsis with or without bloodstream infection, 4.4% vs 1.5%; P =.07; incidence density of 4.5 vs 1.2 per 1000 catheter-days), as well as of overall thrombotic complications (21.5% vs 1.9%; P<.001) and complete thrombosis of the vessel (6% vs 0%; P =.01); rates of overall and major mechanical complications were similar between the 2 groups (17.3% vs 18.8 %; P =.74 and 1.4% vs 2.8%; P =.44, respectively). Risk factors for mechanical complications were duration of insertion (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.03-1.08 per additional minute; P<.001); insertion in 2 of the centers (OR, 4.52; 95% CI, 1.81-11.23; P =.001); and insertion during the night (OR, 2.06; 95% CI, 1.04-4.08; P =.03). The only factor associated with infectious complications was femoral catheterization (hazard ratio [HR], 4.83; 95% CI, 1.96-11.93; P<.001); antibiotic administration via the catheter decreased risk of infectious complications (HR, 0.41; 95% CI, 0.18-0.93; P =.03). Femoral catheterization was the only risk factor for thrombotic complications (OR, 14.42; 95% CI, 3.33-62.57; P<.001).
                Femoral venous catheterization is associated with a greater risk of infectious and thrombotic complications than subclavian catheterization in ICU patients.
Subclavian and internal jugular CVA routes have similar risks for catheter-related complications in long-term catheterization in cancer patients. Subclavian CVA is preferable to femoral CVA in short-term catheterization because of lower risks of catheter colonization and thrombotic complications. In short-term haemodialysis catheterization, femoral and internal jugular CVA routes have similar risks for catheter-related complications except internal jugular CVA routes are associated with higher risks of mechanical complications.
