    Repeatedly catheterising the internal jugular vein percutaneously through the same site, between the heads of the sternomastoid, resulted in soft tissue cleavage planes. The catheter entered the pleural cavity from the superior vena cava, a site remote from the percutaneous entry.
    The internal jugular line can be misplaced in spite of respiratory fluctuation, free flow, and reflux with the container lowered below cardiac level. Radiological confirmation is mandatory.

    This is a case report of a patient with difficult venous access following thrombosis of major superficial and deep veins of the limbs as documented by ultrasound doppler and venography. The insertion of a few central ports were infected and the vein thrombosed. Venography revealed that central venous access was no longer feasible. The previous laparotomies had resulted in dense intra-peritoneal adhesions, and rendered further laparotomy virtually impossible. The patient had occasional adhesion colics, vomiting and hypoglycemic episodes. A rarely performed retro-peritoneal approach of inserting an improved non-heparinised port proved to be effective for long-term management of this patient. The surgical approach and the selected port are discussed.

    Hickman catheters have previously been conventionally placed by surgical dissection. This usually performed by experienced surgeons and is carried out under general anaesthesia. We report our preliminary experience in Hickman catheter placement by percutaneous technique in twenty patients. We outline the implantation methods and complications encountered by this technique. The procedure is relatively simple provided the operator is skilled in central venous cannulation. The chief advantages are that the procedure can be done under local anaesthesia and results in less trauma compared with surgical dissection. Such an alternative in catheter insertion would promote wider usage of Hickman catheters in cancer patients.

    Point-of-care ultrasound is currently widely used across the landscape of pediatric care. Ultrasound machines are now smaller, are easier to use, and have much improved image quality. They have become common in emergency departments, ICUs, inpatient wards, and outpatient clinics. Recent growth of supportive evidence makes a strong case for using point-of-care ultrasound for pediatric interventions such as vascular access (in particular, central-line placement), lumbar puncture, fluid drainage (paracentesis, thoracentesis, pericardiocentesis), suprapubic aspiration, and soft tissue incision and drainage. Our review of this evidence reveals that point-of-care ultrasound has become a powerful tool for improving procedural success and patient safety. Pediatric patients and clinicians performing procedures stand to benefit greatly from point-of-care ultrasound, because seeing is believing.

    Objective: We compared sonoanatomy of the internal jugular vein (IJV) the high (HA), conventional (CA) and the medial oblique approach (MA) to identify the best approach and head position for IJV cannulation.

    Materials & Methods: Total of 45 volunteers aged 18-65 years were included in this study. The degree of overlap in percentage, depth of IJV from skin, antero-posterior (AP) and transverse diameters (TD) of IJV were measured in real time with ultrasound (US). Measurements were taken in the HA, CA and MA in neutral and 30° head rotation on both the right and left side of the neck.

    Results: The HA had lower percentage of overlap when compared to CA and MA in neutral and 30° head rotation (p= 0.002 to ≤0.001). The IJV was more shallow in the CA and MA. The AP and TD of the IJV were larger in the MA when compared to HA (p=<0.001) and CA (p =0.026 to < 0.001) and the right IJV has a larger AP and TD in all approaches.

    Discussion: The HA had the least percentage of overlap compared to CA and MA, therefore the risk of accidental ICA puncture can be reduced. The apparent overlap seen in MA may not reflect the actual scenario because of the way the US beam cuts the vessel. The AP and TD of IJV were significantly increased in the MA, which would ease CVC.

    Conclusion: We conclude and recommend the medial oblique probe position with 30° head rotation provides optimal real time sonographic parameters for US guided IJV cannulation.

    The use of intravascular hypothermia in the treatment of hemorrhagic stroke is currently still being researched. The exact therapeutic properties and effect of hypothermia on the natural progression of the disease are not known, and a only small number of papers has been published with results from these studies. Mild hypothermia at 34°C was induced in six patients with hemorrhagic stroke in the first 48 h after presentation, using an intravascular catheter placed in the inferior vena cava. The hypothermia was induced and maintained for 24 h followed by gradual rewarming. Another 18 patients with hemorrhagic stroke but not receiving hypothermia were then taken as the control group, and all patients were treated with standard stroke management. The patients were then followed up using the modified Rankin Scale (mRS) for 6 months and 1 year. There was a statistically significant improvement at 6 months and 1 year follow-up using the mRS score in the hypothermia group, indicating a possible beneficial effect of early therapeutic hypothermia in the management of acute hemorrhagic stroke. However, a larger study is needed in order to confirm our finding.

    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).

    A young lady with an arteriovenous (AV) fistula on hemodialysis was referred for surgical management following a failed endovascular approach to relieve central venous occlusion. She had an obstructed left brachiocephalic vein with a history of numerous central vein catheter placements. Alternative routes for new arteriovenous fistula creation had been exhausted due to previous contralateral upper limb fistula rupture and ligation. To the best of our knowledge, no similar cases of airway obstruction in central venous occlusion occurring in hemodialysis patients with AV fistula have been reported. The importance of identifying the possible emergency red flags in hemodialysis patients with central venous occlusion is important to prevent unwanted consequences.

    BACKGROUND: Noncuffed catheters (NCC) are often used for incident hemodialysis (HD) patients without a functional vascular access. This, unfortunately results in frequent catheter-related complications such as infection, malfunction, vessel stenosis, and obstruction, leading to loss of permanent central venous access with superior vena cava obstruction. It is important to preserve central vein patency by reducing the number of internal jugular catheter insertions for incident HD patients with a functional vascular access. We sought to achieve this by introducing in-patient intermittent peritoneal dialysis (IPD) as bridging therapy while awaiting establishment of long-term vascular access for HD patients.

    METHODS: Incident HD patients without permanent vascular access encountered from January to December 2014 were included in this study. Patients were divided into 2 groups: Group 1 were encountered within 6 months prior to introduction of in-patient IPD bridging therapy in substitution of noncuffed catheter (NCC) insertion while awaiting maturation of permanent vascular access. Group 2 were encountered within 6 months after the introduction of this policy. The number of NCC and peritoneal dialysiscatheter insertion, along with catheter-related infections were evaluated during this period.

    RESULTS: Approximately 450 patients were distributed in each group. We achieved 45% reduction in internal jugular catheter insertion from 322 to 180 catheters after policy change. This led to a significant drop in catheter-related blood stream infection (53%, P <0.001). On the other hand, 30% more peritoneal dialysiscatheter were inserted to accommodate our IPD bridging therapy.

    CONCLUSIONS: The introduction of IPD as bridging therapy while awaiting maturation of permanent vascular access significantly reduced the utilization of NCC in incident HD patients and catherter-related blodstream infection. With this, it is our hope that it will contribute to the preservation of central vein patency.

    Background: The efficacy of antimicrobial central venous catheters (CVCs) remains questionable. In this network meta-analysis, we aimed to assess the comparative efficacy of antimicrobial CVC impregnations in reducing catheter-related infections in adults.

    Methods: We searched 4 electronic databases (Medline, the Cochrane Central Register of Controlled Trials, Embase, CINAHL) and internet sources for randomized controlled trials, ongoing clinical trials, and unpublished studies up to August 2016. Studies that assessed CVCs with antimicrobial impregnation with nonimpregnated catheters or catheters with another impregnation were included. Primary outcomes were clinically diagnosed sepsis, catheter-related bloodstream infection (CRBSI), and all-cause mortality. We performed a network meta-analysis to estimate risk ratio (RR) with 95% confidence interval (CI).

    Results: Sixty studies with 17255 catheters were included. The effects of 14 impregnations were investigated. Both CRBSI and catheter colonization were the most commonly evaluated outcomes. Silver-impregnated CVCs significantly reduced clinically diagnosed sepsis compared with silver-impregnated cuffs (RR, 0.54 [95% CI, .29-.99]). When compared to no impregnation, significant CRBSI reduction was associated with minocycline-rifampicin (RR, 0.29 [95% CI, .16-.52]) and silver (RR, 0.57 [95% CI, .38-.86]) impregnations. No impregnations significantly reduced all-cause mortality. For catheter colonization, significant decreases were shown by miconazole-rifampicin (RR, 0.14 [95% CI, .05-.36]), 5-fluorouracil (RR, 0.34 [95% CI, .14-.82]), and chlorhexidine-silver sulfadiazine (RR, 0.60 [95% CI, .50-.72]) impregnations compared with no impregnation. None of the studies evaluated antibiotic/antiseptic resistance as the outcome.

    Conclusions: Current evidence suggests that the minocycline-rifampicin-impregnated CVC appears to be the most effective in preventing CRBSI. However, its overall benefits in reducing clinical sepsis and mortality remain uncertain. Surveillance for antibiotic resistance attributed to the routine use of antimicrobial-impregnated CVCs should be emphasized in future trials.
