However, healthcare professionals are commonly worried about the possible consequences that may result using a central venous access device(CVAD)(mainly, bloodstream infections and thrombosis), both peripherally inserted central catheters(PICCs) and centrally inserted central catheters(CICCs). This review aims to discuss indications, insertion techniques, and care of PICCs in critically ill patients. PICCs have many advantages over standard CICCs. First of all, their insertion is easy and safe-due to their placement into peripheral veins of the armand the advantage of a central location of catheter tip suitable for all osmolarity and p H solutions. Using the ultrasound-guidance for the PICC insertion, the risk of hemothorax and pneumothorax can be avoided, as wellas the possibility of primary malposition is very low. PICC placement is also appropriate to avoid post-procedural hemorrhage in patients with an abnormal coagulative state who need a CVAD. Some limits previously ascribed to PICCs(i.e., low flow rates, difficult central venous pressure monitoring, lack of safety for radio-diagnostic procedures, single-lumen) have delayed their start up in the intensive care units as common practice. Though, the recent development of power-injectable PICCs overcomes these technical limitations and PICCs have started to spread in critical care settings. Two important take-home messages may be drawn from this review. First, the incidence of complications varies depending on venous accesses and healthcare professionals should be aware of the different clinical performance as well as of the different risks associated with each type of CVAD(CICCs or PICCs). Second, an inappropriate CVAD choice and, particularly, an inadequate insertion technique are relevant-and often not recognized-potential risk factors for complications in critically ill patients. We strongly believe that all healthcare professionals involved in the choice, insertion or management of CVADs in critically ill patients should know all potential risk factors of complications. This knowledge may minimize complications and guarantee longevity to the CVAD optimizing the risk/benefit ratio of CVAD insertion and use. Proper management of CVADs in critical care saves lines and lives. Much evidence from the medical literature and from the clinical practice supports our belief that, compared to CICCs, the so-called power-injectable peripherally inserted central catheters are a good alternative choice in critical care.展开更多

However, complications can be devastating. We present a case of a fatal septic shock due to vertebral osteomyelitis after PVC-related Staphylococcus aureus bacteremia (SAB). Staphylococcus aureus is a leading cause of bacteraemia in both the community and the hospital with a significantly increased incidence over the last several decades. Intravascular catheters are the most common cause of SAB. Morbidity and mortality are high, even with appropriate therapy. Although complications are known and common, they may be difficult to recognize. Vertebral osteomyelitis is one of these known severe complications.展开更多

METHODS: Three commonly used transthoracic echocardiography(TTE) views were used to confirm PAC position in 103 patients undergoing elective cardiac surgery- the parasternal short axis right ventricular inflow-outflow view; the subcostal short axis right ventricular inflow-outflow view; and the parasternal short axis ascending aortic view. All PACs were inserted by the managing anesthesiologist under pressure waveform guidance alone, who was blinded to all sonographic information. A sonographer blinded to all pressure waveform information confirmed visualisation of an "empty" PA before PAC insertion, and visualisation of the PAC balloon in the main PA(MPA) or right PA(RPA) after attempts at placement were complete. Agreement, sensitivity and specificity of TTE in confirming appropriate PAC placement was compared against pressure waveformguidance as the "gold standard". The successful view used was compared against patients' anthropomorphic indices, presence of lung hyperinflation, and insertion of PAC during positive pressure ventilation. Agreement between TTE and pressure waveform guidance was analysed using Cohen's Kappa statistic. The relative proportion of total RPA seen by subcostal vs parasternal TTE views was also compared with a further 20 patients' computed tomography(CT) pulmonary angiograms(CTPA), to determine efficacy in detection of distal RPA PAC placement. RESULTS: Appropriate positioning of the PAC balloon, and its to-and-fro movement consistent with a nonwedged state, within the MPA or RPA was confirmed by TTE in 98 of the 103 patients [sensitivity 95%(95%CI: 89%-98%)], and absence of the PAC balloon before insertion correctly established in 100 patients [specificity 97%(92%-99%)]. This was in very good agreement with pressure waveform guidance [Cohen's Kappa 0.92,(0.87-0.98)]. The subcostal view was the best view to visualise the PAC tip when it was placed in the right pulmonary artery(OR 70, P < 0.0001), was more successful in patients with COAD(OR 9.5, P = 0.001), and visualized 61%(vs 44% by parasternal views, P < 0.001) of mean RPA lengths compared with CTPA; however the parasternal views were more successful in patients with higher body mass indexs(OR 0.78 for success with subcostal views, P < 0.001). There was a trend towards insertion during intermittent positive pressure ventilation favoring visualisation by subcostal views(OR 3.9, P = 0.08). The subcostal view visualized a greater length of the RPA than parasternal views(3.9 cm vs 2.9 cm, P < 0.0001). PACs were more often placed in the MPA than RPA(80 vs 18 patients). Three patient's pulmonary arteries were not visible by any TTE view; in a further 2 patients, despite preinsertion visualisation of their pulmonary arteries, the PAC balloon was not visible by any view with TTE where correct placement by pressure waveform was unequivocal.展开更多

Method: A prospective cohort study was carried out over a 9-month period from February to October 2016 involving 144 inpatients at PICU of Irmandade da Santa Casa de Sao Paulo Hospital, undergoing central venous catheterization. The patients were matched in pairs of identical patients according to the levels of potentially intervening variables (age, nutritional status, puncture site, professional experience), differing only as to the CVC technique: ultrasound-guided (USG-CVC) or conventional (C-CVC). Discarding data from non-paired patients, the remaining did forming 47 pairs, matched as two related samples: USG-CVC and C-CVC groups. Success parameters: number of puncture attempts;time spent at CVC;success rate and complications. Results: In the USG-CVC group, the number of attempts (mean = 2.04) and the time spent at catheterization (mean = 11.89 minutes) were lower (t = 2.34, df = 46, t 0.95 = 2.02, p t = 3.07, df = 46, t 0.95 = 2.02, p < 0.05), respectively, when compared to the results obtained for the control group (C-GVC), (mean = 3.21) and (mean = 28.26 minutes), respectively. As to success, there was observed a significant difference (F (1, 46) = 16.6;Q (1) = 12.5, p < 005) when considering only one trial (USG -CVC = 27/47;C-CVC = 9/47), but no significant difference (F (1, 46) = 3.76;Q (1) = 3.56, p > 0.05) when considering several attempts. Complications were found less frequently in the USG-CVC group (3/47) than in the CVC-C (13/47), (F (1, 46) = 8.24;Q (1) = 7.14, p < 0.05). Conclusion: USG-CVC was found to be more effective than the conventional technique, especially regarding success at the first puncture attempt.展开更多

Compared to developed countries, there is a shortage of skilled human resources, lower availability of technological resources, greater difficulty of access and a higher incidence of infections, including both those acquired prior to admission and those resulting from treatment and hospitalization (i.e., healthcare-associated infections (HAIs)). HAIs in the PICU include ventilator-associated pneumonia and catheter-related bloodstream infections. Actions for the prevention of HAIs can minimize the occurrence of negative outcomes. Materials and Methods: This is an epidemiological study comparing admissions at the PICU of a high-complexity hospital in South Brazil over two three-year periods: 2012-2014 (before the measures were adopted) and 2015-2017 (after the measures). The care measures were adopted mainly at the beginning of 2015 and consisted of expansion of physical therapy care, adoption of care protocols, acquisition of new materials and equipment (transparent dressings for central catheters, high-tech mechanical ventilators and multiparametric monitors) and multidisciplinary team training. The frequency of the outcomes mortality, length of PICU stay, diagnosis of catheter-related bloodstream infection, need for and duration of ventilatory support and diagnosis of ventilator-associated pneumonia were compared between the two trienniums using logistic regression with adjustment for age in months and need of vasoactive drugs. Results: A total of 1140 admissions were analyzed (470 in the first triennium and 670 in the second), representing an increase in the admission rate of 42.6% after the adoption of the measures. After adjustments, significant reductions in the frequency of mortality (adjusted OR [adjOR] = 0.54;CI 95%: 0.34 - 0.84), length of PICU stay > 7 days (adjOR = 0.75;CI 95%: 0.57 - 0.97) and duration of ventilatory support > 7 days (adjOR = 0.54;CI 95%: 0.39 - 0.74) were observed. Conclusion: The results indicate the benefits of care measures for children admitted to the PICU in terms of a reduction in adverse events and expansion of access.展开更多

文摘AIM: To investigate the utility of transthoracic echocardiography in confirming appropriate pulmonary artery catheter(PAC) placement. METHODS: Three commonly used transthoracic echocardiography(TTE) views were used to confirm PAC position in 103 patients undergoing elective cardiac surgery- the parasternal short axis right ventricular inflow-outflow view; the subcostal short axis right ventricular inflow-outflow view; and the parasternal short axis ascending aortic view. All PACs were inserted by the managing anesthesiologist under pressure waveform guidance alone, who was blinded to all sonographic information.

Results: In the USG-CVC group, the number of attempts (mean = 2.04) and the time spent at catheterization (mean = 11.89 minutes) were lower (t = 2.34, df = 46, t 0.95 = 2.02, p t = 3.07, df = 46, t 0.95 = 2.02, p < 0.05), respectively, when compared to the results obtained for the control group (C-GVC), (mean = 3.21) and (mean = 28.26 minutes), respectively. As to success, there was observed a significant difference (F (1, 46) = 16.6;Q (1) = 12.5, p < 005) when considering only one trial (USG -CVC = 27/47;C-CVC = 9/47), but no significant difference (F (1, 46) = 3.76;Q (1) = 3.56, p > 0.05) when considering several attempts. Complications were found less frequently in the USG-CVC group (3/47) than in the CVC-C (13/47), (F (1, 46) = 8.24;Q (1) = 7.14, p < 0.05). Conclusion: USG-CVC was found to be more effective than the conventional technique, especially regarding success at the first puncture attempt.
文摘Introduction: In low- and middle-income countries, including Brazil, conditions that favor mortality in the PICU remain significant. Compared to developed countries, there is a shortage of skilled human resources, lower availability of technological resources, greater difficulty of access and a higher incidence of infections, including both those acquired prior to admission and those resulting from treatment and hospitalization (i.e., healthcare-associated infections (HAIs)). HAIs in the PICU include ventilator-associated pneumonia and catheter-related bloodstream infections. Actions for the prevention of HAIs can minimize the occurrence of negative outcomes. Materials and Methods: This is an epidemiological study comparing admissions at the PICU of a high-complexity hospital in South Brazil over two three-year periods: 2012-2014 (before the measures were adopted) and 2015-2017 (after the measures). The care measures were adopted mainly at the beginning of 2015 and consisted of expansion of physical therapy care, adoption of care protocols, acquisition of new materials and equipment (transparent dressings for central catheters, high-tech mechanical ventilators and multiparametric monitors) and multidisciplinary team training. The frequency of the outcomes mortality, length of PICU stay, diagnosis of catheter-related bloodstream infection, need for and duration of ventilatory support and diagnosis of ventilator-associated pneumonia were compared between the two trienniums using logistic regression with adjustment for age in months and need of vasoactive drugs. Results: A total of 1140 admissions were analyzed (470 in the first triennium and 670 in the second), representing an increase in the admission rate of 42.6% after the adoption of the measures. After adjustments, significant reductions in the frequency of mortality (adjusted OR [adjOR] = 0.54;CI 95%: 0.34 - 0.84), length of PICU stay > 7 days (adjOR = 0.75;CI 95%: 0.57 - 0.97) and duration of ventilatory support > 7 days (adjOR = 0.54;CI 95%: 0.39 - 0.74) were observed. Conclusion: The results indicate the benefits of care measures for children admitted to the PICU in terms of a reduction in adverse events and expansion of access.
