Impact of different syringe pumps on red cells during paediatric simulated transfusion.

BACKGROUND: Critically ill patients frequently need blood transfusions. For safety, blood must be delivered via syringe infusion pumps, yet this can cause red cell damage and increase the rate of haemolysis. AIMS AND OBJECTIVES: To evaluate biochemical and haemolytic markers of red blood cells transfused in three different types of syringe infusion pumps at two different infusion rates (10 and 100 mL/h). DESIGN AND METHODS: A lab-based study using aliquots of 16 red blood cell bags was undertaken. Haemolysis markers (total haemoglobin [g/dL], haematocrit [%], free haemoglobin [g/dL], potassium [mmol/L], lactate dehydrogenase [U/L], osmolality [mOsm/kg], pH, degree of haemolysis [%]) were measured before and after red blood cell infusion and exposure. Three different syringe infusion pumps brands (A, B, and C) were compared at two different infusion rates (10 and 100 mL/h). RESULTS: Total haemoglobin fell significantly in all red blood cell units during manipulation (pre-infusion: 26.44 ± 5.74; post-exposure: 22.62 ± 4.00; P = .026). The degree of haemolysis significantly increased by 40% after manipulation of the red blood cells. Syringe infusion pump A caused a 3-fold increase in potassium levels (3.78 ± 6.10) when compared with B (-0.14 ± 1.46) and C (1.63 ± 1.98) (P = .015). This pump also produced the worst changes, with an increase in free haemoglobin (0.05 ± 0.05; P = .038) and more haemolysis (0.08 ± 0.07; P = .033). There were significant differences and an increase in the degree of haemolysis (P = .004) at the infusion rate of 100 mL/h. CONCLUSIONS: Syringe infusion pumps may cause significant red blood cell damage during infusion, with increases in free haemoglobin, potassium, and the degree of haemolysis. Some pump types, with a cassette mechanism, caused more damage. RELEVANCE TO CLINICAL PRACTICE: In many intensive care units, bedside nurses are able to consider infusion pump choice, and understanding the impact of different pump types on red blood cells during a transfusion provides the nurses with more information to enhance decision-making and improve the quality of the transfusion.

Effect of warming and infusion of red blood cell concentrates on markers of haemolysis: An ex vivo simulation study.

BACKGROUND: Transfusion of red blood cell (RBC) concentrates is a common procedure to restore blood volume and tissue oxygen delivery in patients with trauma. Although RBC warmers may prevent hypothermia, some warming or infusion equipment may lead to haemolysis and patient injury. OBJECTIVES: The aim of this study was to test the effect of (i) RBC warming and (ii) administration via manual vs. pump infusion on haemolysis. METHODS: This experimental ex vivo study studied haemolysis markers of RBC injury. The sample consisted of 90 RBC infusions in two simulations, randomly, 45 warmed RBC infusions and 45 nonwarmed RBC infusions, in two or three stages: before the intervention (baseline-warming, N= 45; nonwarming, N= 45), after water bath warming at 42 °C (warmed, N= 45), and then after the warmed or nonwarmed RBCs were infused by manual or pump infusion at a rate of 100 mL/h (infusion-warming, N= 45; nonwarming, N= 45). RESULTS: Warmed RBCs showed significantly lower total haemoglobin (Hb) and haematocrit levels and increase in free Hb levels, haemolysis levels, and lactate dehydrogenase (LDH) activity (all p<0.05) than baseline RBCs. Pump infusion RBCs were associated with reduced total Hb and increased free Hb, haemolysis, and potassium (K) levels (all p<0.05) compared with warmed RBCs. In contrast, manual infusion of warmed RBCs resulted in significantly reduced total Hb levels and increased LDH activity (both <0.05). After infusion, total Hb, free Hb, haematocrit, haemolysis, and LDH values were significantly different for warmed vs. nonwarmed RBCs (p<0.05). CONCLUSIONS: Haemolysis biomarkers increase with RBC warming and infusion, especially when using infusion pumps. Critically ill patients should be carefully monitored for possible complications during and after RBC infusion.

Evaluating pharmaceutical waste disposal in pediatric units.

OBJECTIVE: To verify the disposal of pharmaceutical waste performed in pediatric units. METHOD: A descriptive and observational study conducted in a university hospital. The convenience sample consisted of pharmaceuticals discarded during the study period. Handling and disposal during preparation and administration were observed. Data collection took place at pre-established times and was performed using a pre-validated instrument. RESULTS: 356 drugs disposals were identified (35.1% in the clinic, 31.8% in the intensive care unit, 23.8% in the surgical unit and 9.3% in the infectious diseases unit). The most discarded pharmacological classes were: 22.7% antimicrobials, 14.8% electrolytes, 14.6% analgesics/pain killers, 9.5% diuretics and 6.7% antiulcer agents. The most used means for disposal were: sharps' disposable box with a yellow bag (30.8%), sink drain (28.9%), sharps' box with orange bag (14.3%), and infectious waste/bin with a white bag (10.1%). No disposal was identified after drug administration. CONCLUSION: A discussion of measures that can contribute to reducing (healthcare) waste volume with the intention of engaging reflective team performance and proper disposal is necessary. OBJETIVO: Verificar o descarte dos resíduos de medicamentos realizado em unidades pediátricas. MÉTODO: Estudo descritivo e observacional, realizado em um hospital universitário.

Michigan appropriateness guide for intravenous catheters in pediatrics - miniMAGIC-Brasil: translation into Brazilian portuguese.

OBJECTIVE: To perform the translation and adaptation of the Michigan Appropriateness Guide for Intravenous Catheters in Pediatrics (miniMAGIC) into Brazilian Portuguese. METHODS: Methodological study performed in five recommended stages: initial translations; synthesis of the translations; back translations; assessment of the back translations; expert committee assessment. The expert committee was composed of three registered nurses and two doctors who had a Master's and/or PhD degree, and an expertise in intravenous therapy and pediatric and neonatal care. To assess the semantic, idiomatic, experiential and conceptual adequacy, a Likert scale was applied, in which 1, "not equivalent"; 2, "inequivalent"; 3, "cannot assess"; 4, "quite equivalent"; 5, "totally equivalent". The terms mostly analyzed as negative in equivalence and with a lower than 20 score were reviewed and submitted to a new assessment, with the Delphi Technique until consensus was obtained. The results were stored in electronic spreadsheets and treated with concordance index, with a minimum acceptable result of 0.80. RESULTS: The content of all recommendations, named as miniMAGIC-Brasil, was validated by the expert committee after two stages of evaluation. All recommendations had an overall agreement index of 0.91. CONCLUSIONS: The miniMAGIC-Brazil guide was validated in respect to the adequacy of the translation after two steps.

[Assertiveness and peripheral intravenous catheters dwell time with ultrasonography-guided insertion in children and adolescents]. / Assertividade e tempo de permanência de cateteres intravenosos periféricos com inserção guiada por ultrassonografia em crianças e adolescentes.

Randomized controlled trial which aimed to verify whether the use of vascular ultrasound (VUS) increases assertiveness in the use of peripheral venous catheter in children, and the catheter dwell time, when compared to traditional puncture. Data were collected after approval of theethical merit. Children and adolescents undergoing VUS-guided peripheral intravenous (GVUS) or puncture guided by clinical assessment of the venous conditions(CG) were included in the study. Significance level was set at p< or =0.05. The sample was composed of 382 punctures, 188 (49.2%) in VUS Gand 194 (50.8%) in CG, performed in 335 children. Assertiveness was found in 73 (71.6%) GVUS catheters and in 84(71.8%) of the CG (p=0.970), and catheter dwell time presented a median of less than one day in both groups (p=0.121), showing nostatistically significant difference. VUS did not significantly influence the results of the dependent variables investigated. ClinicalTrials.govNCT00930254.

Placement of peripherally inserted central catheters in children guided by ultrasound: a prospective randomized, and controlled trial.

OBJECTIVE: To compare the use of vascular Doppler ultrasound with vein visualization and palpation for positioning peripherally inserted central catheters in children and to determine the influence of these methods on the success of the first puncture attempt, catheter positioning, and time required for the accomplishment. DESIGN: A prospective randomized, controlled trial was conducted in a university hospital after ethical approval and was carried out among children (from birth to 18 yrs). SETTING: São Paulo Hospital, São Paulo, Brazil. PATIENTS: The sample comprises 42 peripherally inserted central catheters insertions allocated randomly into two groups: 1) an ultrasound group with 21 peripherally inserted central catheters guided by ultrasound; and 2) a control group with 21 catheters, in which the peripherally inserted central catheters were inserted using vein visualization and palpation. INTERVENTIONS: The procedure was performed by two trained nurses using a standard protocol for peripherally inserted central catheter insertion and ultrasound use. Ultrasound group equipment was ILook25 (Sonosite, Bothell, WA) with a 25-mm, 10- to 15-MHz linear array transducer that reaches a 4-cm depth. MEASUREMENTS AND MAIN RESULTS: Success in the first puncture attempt was higher (p = .003) in the ultrasound group (90.5%) than in the control group (47.6%). The catheter positioning success rate was 85.7% in the ultrasound group and 52.4% in the control group (p = .019). The median time spent on the procedure for the ultrasound group was 20 mins, whereas it was 50 mins for the control group (p = .001). CONCLUSION: The use of ultrasound increased the successful positioning of peripherally inserted central catheters in comparison with the venous anatomic landmark visualization and palpation technique and further optimized the time spent on the procedure.

Oral care and oropharyngeal and tracheal colonization by Gram-negative pathogens in children.

BACKGROUND: Critical care nursing interventions to oral care can reduce microorganisms in the oropharynx available for translocation. OBJECTIVES: To analyse the effect of 0·12% chlorhexidine digluconate on the colonization of oropharyngeal and tracheal secretions by Gram-negative pathogens in mechanically ventilated children. METHODS: A randomized, controlled and double-blinded study was performed in the paediatric intensive care unit (PICU) of a Brazilian university hospital. Exclusion criteria included child age under 28 days, pneumonia diagnosis at admission, use of tracheostomy, PICU length of stay (LOS) less than 48 h and refusal to participate. Children were randomly allocated to the interventional group (IG), in which oral care with chlorhexidine was administered, or to the placebo group (PG), which received oral care without antiseptic use. The data were analysed through Pearson's χ(2) test, Fisher's exact and ANOVA tests with significance levels set at 0·05. RESULTS: The demographic characteristics of the 74 children were not statistically different between groups. No between-group differences in oropharyx colonization by Gram-negative pathogens were identified (p = 0·316). Pathogens were isolated in the tracheal secretions of two (10·0%) children in the PG and four (19·0%) children in the IG (p = 0·355). CONCLUSION: The use of chlorhexidine did not significantly influence the colonization of oropharyngeal and tracheal secretions by Gram-negative pathogens of the studied sample. RELEVANCE TO CLINICAL PRACTICE: This study demonstrated no influence of a specific antiseptic agent on colonization profile of mechanically ventilated children in PICU. Further research in this field is necessary to promote evidence-based nursing practice on oral care of critically ill children.

[Care bundle to reduce central venous catheter-related bloodstream infection: an integrative review]. / Método bundle na redução de infecção de corrente sanguínea relacionada a cateteres centrais: revisão integrativa.

This is an integrative review of literature aimed to identify evidence-based interventions which make up care bundles to reduce central venous catheter-related or associated bloodstream infections. To collect data in Brazilian and international databases were used the key word bundle and the descriptors catheter-related infection, infection control and central venous catheterization, resulting in fifteen articles, after inclusion criteria application. This work showed five interventions as those commonly employed in the bundles methods: hand hygiene, chlorhexidine gluconate for skin antisepsis, use of maximal sterile barrier precaution during the catheter insertion, avoid the femoral access and daily review of catheter necessity with prompt removal as no longer essential. The majority of the studies showed a significant reduction in bloodstream infection related to or associated with central venous catheters.

[Hydrogen potential of antibiotic solutions subjected to environmental conditions: a preliminary trial]. / Potencial hidrogeniônico de soluções de antibióticos submetidas a condições ambientais: ensaio preliminar.

This experimental study was performed to assess the hydrogen potential (pH) of the antimicrobials ceftriaxone sodium, vancomycin hydrochloride, metronidazole, penicillin G potassium, and amikacin sulphate, following reconstitution, diluted with NaCl 0.9% (SF) and glucose solution 5% (GS), at eight different time intervals and under the normal daily conditions of lighting and temperature within the hospital unit (no air conditioning). The objective of this study was to verify the changes in the acid-base behavior of the solutions, which indicate chemical instability and can be associated with complications during intravenous therapy. Of the 186 analyzed pH values, there were no variations greater than 1.0 and no physical alterations visible to the naked eye. All solutions had a pH less than 7, and there were no significant differences for clinical practice regarding the diluent. The mean pH values after dilution with SF and GS for vancomycin hydrochloride, metronidazole, and amikacin sulphate are a risk factor for the development of intravenous complications due to their extreme acidity.

Start-up delay in syringe infusion pumps with different rates and priming techniques of intravenoust sets.

OBJECTIVE: To investigate infusion pumps start-up delay according to different brands of infusion pumps, flow rates and intravenous sets priming techniques. METHOD: The experimental study simulated clinical practice under controlled conditions, using a 50 mL syringe with NaCl 0.9% solution, two syringe infusion pumps (A and B), six rates (0.3, 0.5, 1.0, 5, 10 and 20 mL/h), two purging techniques (manually or infusion pump's electronic bolus). Data were analyzed according to mean, standard deviation, Student's t and ANOVA tests (p<0.05). RESULTS: The start-up delay was greater in low rates regardless the priming technique. The electronic bolus increased the infusion pump A accuracy at 0.3mL/h (p=0.010), 0.5 mL/h (p=0.002) and 1.0mL/h (p=0.004). Pump's accuracy in all studied rates and manual IV sets filling was similar. CONCLUSION: In low infusion rates the start-up delay was greater despite the infusion pump brand and electronic bolus improved pumps accuracy.

This scale obtained a content validity index of 0.96 and a universal agreement of 0.78. In the cross-cultural adequacy analysis phase, a score of 0.77 was obtained. The majority (90.5%) of the participants judged the scale's decision support property as positive. CONCLUSION: The VIA Scale was validated and culturally adapted to the Brazilian Portuguese language, resulting in the VIA Scale - Revised (VIA-R).

A Pediatric Intensive Care Checklist for Interprofessional Rounds: The R-PICniC Study.

BACKGROUND: The use of checklists in the pediatric intensive care unit can help improve the quality of care and patient safety. OBJECTIVES: To build and validate a checklist for use in interprofessional rounds in a pediatric intensive care unit. METHODS: This methodological study was conducted in a 20-bed pediatric intensive care unit serving children up to 14 years old. A checklist prototype was constructed through review of the literature and achievement of consensus among the professionals providing care in the unit. Content validation was performed using a modified Delphi technique involving specialists with more than 5 years of experience in pediatric intensive care, methodological studies, and patient safety. Content validity ratios were calculated for the elements of the checklist, which were considered valid when they reached values greater than 0.78. The checklist was tested for usability, application time, and effects on patient care, and feedback was obtained from potential users. RESULTS: Before content validation, the checklist contained 11 domains, 32 items, and 6 daily goals. The invitation to validate content was sent to 86 specialists, and content validity was achieved after 2 rounds of evaluation, with the checklist elements having content validity ratios ranging from 0.94 to 0.97. The mean application time of the checklist was 5 minutes. The final version consisted of 11 domains, 33 items, and 8 daily goals. CONCLUSIONS: This study resulted in a useful and valid instrument for application in interprofessional rounds that was tailored to the needs of local health care professionals.

Stability of vancomycin hydrochloride employed in antimicrobial seal solutions of central intravenous catheters. / Estabilidade do cloridrato de vancomicina empregado em soluções de selo antimicrobiano de cateteres intravenosos centrais.

OBJECTIVE: to verify the stability of vancomycin hydrochloride in antimicrobial seal solutions with and without association of heparin sodium according to temperature and association time. METHOD: an experimental study designed for the analysis of hydrogenionic potential and concentration by means of high-efficiency liquid chromatography of vancomycin hydrochloride (n=06) and vancomycin hydrochloride and heparin sodium (n=06). The solutions studied were submitted to absence of light, as well as to 22°C and 37°C. Analyses in triplicate (n=192) were performed at the initial moment (T0) and three (T3), eight (T8) and 24 hours (T24) after preparation. The data were submitted to analysis of variance (p≤0.05). RESULTS: concentration of the antimicrobial at 22°C presented a reduction (T0-T8) and a subsequent increase (T24); hydrogenionic potential decreased significantly over time. At 37°C, the concentration increased up to T3 and decreased at T24, with a reduction of hydrogenionic potential up to 24 hours. Concentration of the vancomycin hydrochloride and heparin sodium solutions varied with a reduction at 22°C, accompanied by increased hydrogenionic potential. Precipitate formation was observed by visual inspection of the vancomycin hydrochloride-heparin sodium association (T3). CONCLUSION: pharmacological stability of vancomycin hydrochloride (5 mg/mL) and physical incompatibility with heparin sodium (100 IU/mL) were evidenced after three hours of association in the antimicrobial seal solutions studied.

Peripheral vascular catheter use in Latin America (the vascular study): A multinational cross-sectional study.

Background: Peripheral intravenous catheter (PIVC) insertion is one of the most common clinical procedures worldwide, yet little data are available from Latin America. Our aim was to describe processes and practices regarding PIVC use in hospitalized patients related to hospital guidelines, characteristics of PIVC inserters, prevalence of PIVC complications, and idle PIVCs. Methods: In 2019 we conducted a multinational, cross-sectional study of adult and pediatric patients with a PIVC in hospitals from five Latin American countries: Argentina, Brazil, Chile, Colombia, and Mexico. We used two data collection tools to collect hospital guidelines and patient-specific data on the day of the study. The vessel health and preservation (VHP) model guided synthesis of the study aims/questions and suggested opportunities for improvement. Results: A total of 9,620 PIVCs in adult (86%) and pediatric inpatients in 132 hospitals were assessed. Routine replacement 8-72 hourly was recommended for adults in 22% of hospitals, rather than evidence-based clinical assessment-based durations, and 69% of hospitals allowed the use of non-sterile tape rather than the international standard of a sterile dressing. The majority (52%) of PIVCs were inserted by registered nurses (RNs), followed by nursing assistants/technicians (41%). Eight percent of PIVCs had pain, hyperemia, or edema, 6% had blood in the extension tubing/connector, and 3% had dried blood around the device. Most PIVCs had been inserted for intravenous medications (81%) or fluids (59%) in the previous 24 h, but 9% were redundant. Conclusion: Given the variation in policies, processes and practices across countries and participating hospitals, clinical guidelines should be available in languages other than English to support clinician skills and knowledge to improve PIVC safety and quality. Existing and successful vascular access societies should be encouraged to expand their reach and encourage other countries to join in multinational communities of practice.

Hydrogen-ion potential of antibiotics according to the environment factors temperature and luminosity.

The objective of this experimental study was to measure the pH of antibiotics administered by intravenous infusion--ceftriaxone sodium, vancomycin hydrochloride, metrodinazole, penicillin G potassium and amikacin sulfate--after reconstitution with sterile water and dilution with NaCl 0.9% or dextrose 5% in water, according to temperature and luminosity of the environment. The results showed that variation in the drugs' pH was less than 1.0 value and that some antibiotics remained acidic after dilution and maintained this chemical profile in all situations studied, suggesting that the studied environmental factors did not change the solutions' acid base characteristic. Some pH values measured characterize risk for the development of chemical phlebitis and infiltration, and it is important for clinical practice to emphasize the profile of intravenous solutions of antibiotics, considering method of dilution, and time to infusion.

Time-related factors for peripheral intravenous catheterization of critical children.

OBJECTIVE: To verify characteristics related to critical children, the catheter, and the professionals that will influence the time for the success of the puncture. METHOD: Descriptive, prospective, and correlation study, collected with an unique instrument, and a sample consisting of 89 children cared for in the emergency room. Statistical analysis of the association between time and explanatory variables was performed, considering a significance of 5%. RESULT: The median time for success was 193.4 seconds. Multivariate analysis showed that hypothermic patients (p=0.009) presented prolonged times for success and that the puncture was performed in a shorter time with Vialon® 22G catheters (p=0.045). CONCLUSION: The median time for success was higher than recommended, being influenced by hypothermia and condition of veins the children. The Vialon® 22G catheter is the most suitable for puncturing critical patients. Thus, the incorporation of new practices and technologies is necessary for success to occur in less time.

Effects of Blood Transfusion Sets on Red Blood Cell Hemolysis.

This experimental randomized study compared the effects of macrodrop and microdrop blood transfusion sets on red blood cell (RBC) hemolysis. Twenty units of packed RBCs from different donors were infused through 48 infusion sets from 2 manufacturers at infusion rates of 10 and 100 mL/h. Pre- and postinfusion analysis was performed to determine total hemoglobin (g/dL), hematocrit (%), free hemoglobin (g/dL), potassium (mmol/L), haptoglobin (g/L), and degree of hemolysis (%). The results demonstrated that the level of free hemoglobin (P < .001) and degree of hemolysis (P < .001) increased postinfusion. A higher degree of hemolysis was noted when the RBCs were infused at a rate of 10 mL/h through a microdrop blood transfusion set.
