The risks and microbiology for peripherally inserted central catheters (PICCs) are less well described than those for traditional central catheters, particularly as they pertain to duration of catheterization. We compared patients with early- and late-onset PICC bloodstream infections at our institution and found significant differences in microbiologic etiologies.

Inadvertent cannulation of the azygos vein can occur during central vein cannulations,especially from the left side. This can cause several complications, including rupture ofthe azygos vein. This complication is unlikely from the more commonly used right internaljugular vein access, although that approach is not free of complications. An abruptcurve at the tip of the central venous catheter showing venous wave forms and highoxygen saturations suggest azygos vein cannulation. Azygos vein cannulations may bemore common in patients with heart failure in which the vein is dilated.

INTRODUCTION: The purpose of this study was to establish the late onset sepsis (LOS) rate of our service, characterize the intestinal microbiota and evaluate a possible association between gut flora and sepsis in surgical infants who were receiving parenteral nutrition (PN). METHODS: Surveillance cultures of the gut were taken at the start of PN and thereafter once a week. Specimens for blood culture were collected based on clinical criteria established by the medical staff. The central venous catheter (CVC) tip was removed under aseptic conditions. Standard laboratory methods were used to identify the microorganisms that grew on cultures of gut, blood and CVC tip. RESULTS: 74 very low birth weight infants were analyzed. All the infants were receiving PN and antibiotics when the gut culture was started. In total, 21 (28.4%) infants experienced 28 episodes of LOS with no identified source. Coagulase negative staphylococci were the most common bacteria identified, both in the intestine (74.2%) and blood (67.8%). All infections occurred in patients who received PN through a central venous catheter. Six infants experienced episodes of microbial translocation. CONCLUSIONS: In this study, LOS was the most frequent episode in neonates receiving parenteral nutrition who had been submitted to surgery; 28.6% of this infection was probably a gut-derived phenomenon and requires novel strategies for prevention.

Abstract Introduction： Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic serious complication during assisted reproductive technology, the aim of our research is to explore the differences of pregnancy outcome between severe OHSS patients and the non-OHSS IVF patients, and also compare the pregnancy outcome of different ascites drainage way of severe OHSS patients.Design: This is a retrospective cohort analysis carried out in a University-affiliated reproductive center from 2012 to 2019 ,between 359 women with severe OHSS following ascites draining and 345 non-OHSS women (matched by age and retrieved oocyte number).We examined the rates of clinical pregnancy, multiple pregnancies, miscarriage, live birth and preterm delivery between the two groups. Within the OHSS group (central venous catheter group vs paracentesis group), odds ratios (ORs) and 95% confidence intervals (CIs) of measure of clinical pregnancy were also analyzed.Result： The biochemical pregnancy loss rate of non-OHSS patients was significantly higher than that of severe OHSS patients (11.1% vs 0.6%) , the live birth, multiple pregnancy (twin pregnancy ) was much more in severe OHSS group than in control group(88.9% vs 73.5%; 57.6% vs 28.1% respectively), and there was no significant difference between singleton and twin preterm rate and neonatal birth weight between OHSS and control group. Binary logistic regression analysis revealed multiple pregnancy and long-protocol showed relatively high odds ratio, suggest that thelong-protocol of COS and multiple pregnancy are the risk factor of severe OHSS.Among severe OHSS following ascites draining, in comparison with abdominal paracentesis and central venous catheter, the ascites volume in central venous catheter group was much more than abdominal paracentesis group, there was significant difference between the two groups. There was no significant difference between the two groups in comparison of live birth, and the birth weight of singleton and twin between these two groups. but the premature birth rate of singleton in group 1 was 9.3% (10/107), whereas in group 2, it was 3.75%.Conclusion： In conclusion, this preliminary report suggests that for the IVF-ET patients, less basic follicle number, GnRH antagonist cycle, singleton maybe the protective factors for the late-onset OHSS. Paracentesis and central venous catheter are all the effective modality to manage the ascites for the severe OHSS patients. For the patients who have the possibility of repeated paracentesis, catheter is a safe and effective way.

As many as 80% of upper-extremity venous thrombosis cases develop in response to an easily identified problem, such as central venous catheter. The remaining 20% of obstructions are caused by other central venous obstruction, trauma, or Paget-Schroetter syndrome. Appropriate clinical indications for upper-extremity venous duplex evaluation include (but are not limited to) unilateral upper-extremity swelling in the presence of indwelling central venous catheter, upper-extremity erythema and tenderness, superficial palpable cord, or facial swelling. Physical examination and thorough patient history compliment the duplex findings to arrive at an accurate diagnosis. The most effective way to determine the presence or absence of thrombosis is with vein wall compressions. However, most of the upper-extremity central vein segments are located beneath bony structures, which prevent extrinsic compression with transducer pressure. Therefore, the spectral Doppler waveform analysis component of the duplex exam becomes crucial in determining venous obstruction. Common technical components and pitfalls include appropriate color and spectral Doppler settings to reliably demonstrate presence/absence of flow or accurate accounting for innominate vein and supraclavicular/infraclavicular subclavian vein versus occluded native anatomy and large patent branches. When properly executed, the aforementioned components comprise a thorough duplex evaluation of the upper extremity venous system.

Catheter Related Bloodstream Infection

Central venous catheters are used frequently in patients on hemodialysis as a bridge to a permanent vascular access. They are prone to frequent complications, including catheter-related bloodstream infection, catheter dysfunction, and central vein obstruction. There is a compelling need to develop new drugs or devices to prevent central venous catheter complications. We convened a multidisciplinary panel of experts to propose standardized definitions of catheter end points to guide the design of future clinical trials seeking approval from the Food and Drug Administration. Our workgroup suggests diagnosing catheter-related bloodstream infection in catheter-dependent patients on hemodialysis with a clinical suspicion of infection (fever, rigors, altered mental status, or unexplained hypotension), blood cultures growing the same organism from the catheter hub and a peripheral vein (or the dialysis bloodline), and absence of evidence for an alternative source of infection. Catheter dysfunction is defined as the inability of a central venous catheter to (1) complete a single dialysis session without triggering recurrent pressure alarms or (2) reproducibly deliver a mean dialysis blood flow of >300 ml/min (with arterial and venous pressures being within the hemodialysis unit parameters) on two consecutive dialysis sessions or provide a Kt/V≥1.2 in 4 hours or less. Catheter dysfunction is defined only if it persists, despite attempts to reposition the patient, reverse the arterial and venous lines, or forcefully flush the catheter. Central vein obstruction is suspected in patients with >70% stenosis of a central vein by contrast venography or the equivalent, ipsilateral upper extremity edema, and an existing or prior history of a central venous catheter. There is some uncertainty about the specific criteria for these diagnoses, and the workgroup has also proposed future high-priority studies to resolve these questions.
