PURPOSE: Peripherally inserted central catheters (PICCs) have become an essential component of the management of an increasing number of patients, including patients who may require hemodialysis. Reported symptomatic venous thrombosis rates associated with PICC lines are based on clinical signs and symptoms and range from 1% to 4%. The purpose of this study is to evaluate the true rate of thrombosis of upper extremity veins after the placement of PICCs and the potential impact on future access in hemodialysis patients. MATERIALS AND METHODS: A retrospective analysis was performed. Patients who had (i) normal findings during initial venography, (ii) PICC placement, and (iii) who underwent subsequent repeated venography were included. Age, sex, vein cannulated, catheter size, location, and incidence of thrombosis were analyzed. RESULTS: Three hundred fifty-four PICCs were placed in 119 patients. Of the 144 extremities, 137 had normal findings during initial venography. Of the 137 extremities, 32 developed thrombosis of the cannulated vein (or central veins) after initial PICC placement (23.3%). When all extremities with multiple PICC lines placed were considered, 52 developed thrombosis, for an overall thrombosis rate of 38%. The incidence of thrombosis by site was cephalic 57%, basilic 14%, and brachial 10%. No significant differences were noted in the rates of thrombosis by age, sex, or catheter size. CONCLUSIONS: There is a relatively high rate of venous thrombosis associated with PICCs, particularly cephalic thrombus. Because of the high rate of thrombosis associated with these catheters, an alternative mode of access should be considered in current or potential hemodialysis patients. All patients with a history of PICC line placement requiring dialysis access should undergo upper extremity venography prior to the placement of permanent access. 相似文献

Venous thrombosis related to peripherally inserted central catheters 总被引:19,自引:0,他引:19
PURPOSE: To determine factors that may lead to venous thrombosis in patients with peripherally inserted central catheters (PICC). MATERIALS AND METHODS: The medical records of 678 patients with 813 PICCs during 1997 were cross-referenced with all patients receiving venous duplex examinations (1,631) during the same time period. Multiple factors were examined in the patients with catheter-related thrombosis, including diagnosis, solution infused, catheter tip position, vein accessed, and catheter diameter. RESULTS: Nurses placed 269 PICCs with 12 venous thromboses, for a rate of 4.5%. Radiologists placed 544 PICCs with 20 venous thromboses, for a rate of 3.7%. There was no significant difference in these rates. The overall thrombosis rate was 3.9%. After multivariate analysis, only catheter diameter remained significant. There were no thromboses in catheters 3 F or smaller. The thrombosis rate was 1% for 4-F catheters, 6.6% for 5-F catheters, and 9.8% for 6-F catheters. CONCLUSIONS: Thrombosis rate associated with PICCs was low (3.9%). The smallest acceptable catheter diameter should be used to decrease the incidence of venous thrombosis. 相似文献

PURPOSE: This study was conducted to evaluate the performance of a sutureless adhesive-backed device, StatLock, for securement of peripherally inserted central venous catheters (PICCs). Earlier studies have demonstrated that StatLock significantly reduces catheter-related complications when compared to tape. The purpose of this study was to determine whether a sutureless securement device offers an advantage over suture in preventing catheter-related complications. MATERIALS AND METHODS: 170 patients requiring PICCs, which were randomized to suture (n = 85) or StatLock (n = 85) securement were prospectively studied. Patients were followed throughout their entire catheter course, and PICC-related complications including dislodgment, infection, occlusion, leakage, and central venous thrombosis were documented. Catheter outcome data were compared to determine if statistically significant differences existed between the suture and StatLock groups. RESULTS: The groups had equivalent demographic characteristics and catheter indications. Average securement time with StatLock was significantly shorter (4.7 minutes vs 2.7 minutes;P <.001). Although StatLock was associated with fewer total complications (42 vs 61), this difference did not achieve significance. However, there were significantly fewer PICC-related bloodstream infections in the StatLock group (2 vs 10; P =.032). One securement-related needle-stick injury was documented during suturing of a PICC. CONCLUSION: The sutureless anchor pad was beneficial for both patients and health care providers. Further investigation to determine how StatLock helps reduce catheter-related blood stream infections is necessary. 相似文献

PURPOSE: To evaluate patient safety, catheter rupture rates, and computed tomography (CT) image quality when using peripherally inserted central catheters (PICCs) in vivo for the power injection of CT contrast media at standard injection rates. MATERIALS AND METHODS: A prospective study to evaluate the safety and effectiveness of power injection of contrast media via indwelling PICCs was performed. Single-lumen and double-lumen polyurethane PICCs (5 F) were injected in vivo with contrast media for clinical CT examinations at injection rates ranging from 1 mL/sec to 4 mL/sec. Data collected included PICC rupture rate, patient complications, injection rate, peak injection pressure, PICC length, PICC age, and quality of contrast enhancement on the CT images. RESULTS: One hundred ten power injections of PICCs for CT examinations were performed. There were 12 injections of single-lumen PICCs and 98 injections of double-lumen PICCs. The most common injection rate was 2 mL/sec, accounting for 89 of the 110 injections (81%). Two PICCs ruptured during power injection, both as a result of operator error. One of the PICCs that ruptured was clamped at the time of injection and the other one was kinked at its venous entry site. One additional PICC showed evidence of dysfunction; it ballooned without actually rupturing. No significant patient complications occurred. Contrast enhancement of the CT images was subjectively rated as average or above average in 95% of cases. CONCLUSIONS: Contrast media can be power-injected via PICCs for routine CT examinations at a rate of 2 mL/sec, yielding satisfactory image quality without exposing patients to significant additional risk. Power injection rates greater than 2 mL/sec, as are typically used in CT angiography applications, were not fully evaluated by this study. 相似文献

OBJECTIVE: The purpose of this study was to evaluate whether a valved peripherally inserted central catheter (PICC) design would result in a lower incidence of occlusion, infection, and malfunction than a clamped catheter. SUBJECTS AND METHODS: Three hundred sixty-two study patients (233 men, 129 women; mean age, 44 years) were randomized to receive a clamped (n = 182) or valved (n = 180) 5-French single-lumen PICC. Catheters were placed under fluoroscopic (n = 331) or sonographic guidance (n = 31). The valved PICC was flushed with saline solution, and the clamped PICC was flushed with a heparin-saline solution. All patients were prospectively followed up at least weekly for catheter status and complications. RESULTS: Percutaneous placement with the catheter tip in the central veins was successful in 99% of patients. Mean dwell time was 34 days. Twenty-six occlusive or infectious complications occurred in the clamped catheter group and 12 in the valved catheter group (p = .02). The clamped and valved catheter groups had 13 and five occlusions, respectively (p = .06), and 12 and five catheter-related blood stream infections, respectively (p = .09). Most occlusions (68%) were treated successfully with urokinase, and site infection or sepsis was treated by catheter removal. CONCLUSION: We found a statistically significant difference in the complication rate for the valved PICC compared with the clamped PICC. With the valved PICC, occlusion and infection were reduced, and patients having these catheters did not require heparin flushes. 相似文献

Placement of peripherally inserted central catheters without fluoroscopy in children: initial catheter tip position 总被引:8,自引:0,他引:8
PURPOSE: To determine how often placement of peripherally inserted central catheters (PICCs) without imaging guidance results in an initially correct central venous catheter tip location. MATERIALS AND METHODS: This study was approved by the hospital's institutional review board, which waived the requirement for informed consent. In a children's hospital, 843 PICCs were placed in 698 patients (age range, 0 days to 26 years; mean, 6.9 years) during a 14-month study period. All PICCs were placed by a specialized team of PICC nurses and interventional radiology technologists in an angiography suite with the supervision of pediatric interventional radiologists. All catheters were threaded blindly to a previously estimated length by either a PICC nurse or a pediatric interventional radiologist, according to National Association of Vascular Access Networks guidelines, and the initial PICC tip location was then determined by means of spot fluoroscopy. PICC tips were regarded as central if they resided anywhere within the superior vena cava (SVC). All catheters were then manipulated with intermittent fluoroscopic guidance to achieve a final central position in the distal third of the SVC. A chi2 test was used to compare initial and final PICC tip locations according to patient age, catheter size, accessed vein, and need for radiologist assistance. A t test was used to compare procedure time with and without radiologist assistance. RESULTS: Analysis included 843 consecutively placed pediatric PICCs, of which 723 (85.8%) had a noncentral initial PICC tip position and required additional manipulation. After catheter repositioning performed with intermittent fluoroscopic guidance, a final central PICC tip location was achieved in 760 PICCs (90.2%). CONCLUSION: Pediatric PICC placement without fluoroscopic guidance required catheter manipulation of initial PICC tip position in 723 cases (85.8%). PICC placement with fluoroscopic guidance is highly successful, and the authors believe it is best performed in an angiography suite. 相似文献

Peripherally inserted central catheters (PICCs) are frequently placed at the bedside. The purpose of our study was to evaluate the efficacy of the Sherlock II tip location system (Bard Access Systems, Salt Lake City, UT), which offers electromagnetic detection of the PICC tip to assist the operator in guiding the tip to a desired location. We performed a retrospective review of patients who had a bedside PICC using the Sherlock II tip location system. Three hundred seventy-five of 384 patients (97.7%) had the catheter tip positioned appropriately. Our results suggest that the Sherlock II tip location system is an efficacious system for bedside PICC placement. 相似文献

The objective of this study was to prospectively determine the incidence of venous thrombosis (VT) in the upper limbs in patients with peripherally inserted central catheters (PICC). We prospectively investigated the incidence of VT in the upper limbs of 26 patients who had PICC inserted. The inclusion criteria were all patients who had a PICC inserted, whilst the exclusion criterion was the inability to perform a venogram (allergies, previous contrast medium reaction and inability of gaining venous access). Both valved and non-valved catheters were evaluated. Prior to removal of the PICC, an upper limb venogram was performed. The number of segments involved with VT were determined. The duration of central venous catheterization was classified as; less than 6 days, between 6 days and 14 days and more than 14 days. VT was confirmed in 38.5% (10/26) of the patients. The majority 85.7% (12/14) were complete occlusive thrombi and the majority of VT only involved one segment. There was no statistical correlation between the site of insertion of the PICC and the location of VT. Neither was there any observed correlation between the occurrence of VT with the patient's history of hypertension, hypercholesterolaemia, coronary artery disease, diabetes mellitus, cardiac insufficiency, smoking or cancer. There was also no statistical correlation with the size of the catheter. In conclusion, PICCs are associated with a significant risk of upper extremity deep vein thrombosis (UEVT). 相似文献

The purpose of this prospective study was to evaluate the efficacy and complications associated with the use of 4-Fr single-lumen non-valved peripherally inserted central venous catheters (PICC) for the infusion of long-term antibiotics. Forty-four non-valved PICC were inserted using micropuncture technique by interventional radiologists. Six patients were lost to unrelated death or follow up. The remaining 38 patients (24 men and 14 women; mean age 54.79 years) were analysed. Catheters were placed under ultrasound guidance using micropuncture technique and subsequently advanced over guidewire through peel-away sheath under fluoroscopic guidance. Doppler ultrasound was used before PICC removal in order to detect possible complications. All non-valved PICC were flushed with 5 ml of heparinized saline before and after each antibiotic infusion. Efficacy was evaluated and analysed on the average duration of catheter patency and whether any complication was present. Procedural success rate was 100% in our patient population. Seven patients had complications necessitating early PICC removal with the average patency duration of 44 days (95% confidence interval 7.79-80.21 days), whereas an average indwelling patency duration of the remaining 31 patients with no complication was 30.58 days (95% confidence interval 25.74-35.43 days). Total complication rate was calculated to be 5.58 incidences per 1000 catheter days. Complication rate associated with the placement and use of 4-Fr non-valved PICC for antibiotic therapy was observed to be low when compared with other studies using valved and non-valved PICC for various infusates. 相似文献

PURPOSE: To analyze the patterns of postplacement tip malposition in peripherally inserted central catheters (PICCs) placed at bedside, and to describe results of bedside and imaging-guided correction of tip malposition. MATERIALS AND METHODS: With use of a quality assurance database, all episodes of tip malposition in PICCs placed at bedside were reviewed. Catheter tip location, success or failure of bedside repositioning (in a subset of patients, by using over-the-wire techniques), findings in the interventional radiology (IR) division, and tip correction method used in the IR suite (repositioning vs replacement) were determined with a review of medical records. RESULTS: During the 18-month study period, 2,367 attempts were made to place a PICC at bedside; 1,654 attempts (70%) were initially successful. Of these, 163 tips (10%) were malpositioned. Complete records for 132 malpositioned tips were available for analysis. Malpositioned tips were located in the ipsilateral internal jugular vein in 45 of the 132 cases (36%), axillary vein in 36 cases (27%), ipsilateral subclavian vein in 25 cases (19%), ipsilateral brachiocephalic vein in 15 cases (11%), contralateral subclavian vein in four cases (3%), contralateral brachiocephalic vein in two cases (2%), contralateral internal jugular vein in one case (1%), and subclavian tributary in one case (1%). In three cases (2%), the tip was coiled in the superior vena cava. Malposition was corrected with catheter exchange in 76 of the 132 cases (58%), repositioning in 48 cases (36%), or removal in one case (1%). Spontaneous correction occurred in seven of the 132 malpositioned tips (5%). One hundred nine tips (83%) were repositioned in the IR division with use of imaging guidance, with 100% success. Twenty-five attempts were made to correct malposition at bedside; 16 of those attempts (64%) were successful. CONCLUSION: Tip malposition is relatively frequent with bedside placement of PICCs. Preliminary data suggest that most malpositions can be corrected with bedside techniques. Spontaneous correction may occur but is relatively uncommon. 相似文献
