Extravasation of medications during peripheral intravenous (PIV) therapy can result in harm to pediatric patients. These medications have physical and/or biologic factors that cause tissue damage. To assist in clinical decisions when using these infusates, an evidence-based table of medications stratified by their relative risk of causing harm if extravasated was developed. Local data and experience, a systematic review of the pediatric literature, and measured pH and osmolality of common pediatric preparations of PIV infusates were used to create a 3-tiered table of PIV infusates categorized by relative risk of causing harm if extravasated.

Central venous catheters and peripherally inserted central catheters are widely used in children with serious chronic diseases. In this report, data about catheters and venous thromboembolic disease (VTE) in children will be reviewed, and the experience of a single academic children’s hospital will be described. Two separate data sets that examine overlapping subpopulations will be reported: (1) the proportion of pediatric patients with catheters who develop VTE and (2) the proportion of patients referred to pediatric hematology for VTE who have catheters. The limitations of current pilot data and the authors' approach to better define this problem and its prevention are discussed.

Rapid fluid resuscitation is used to treat pediatric septic shock. However, achieving fluid delivery goals while maintaining aseptic technique can be challenging. Two methods of fluid resuscitation-the commonly used push-pull technique (PPT) and a new fluid infusion technique using the LifeFlow device (410 Medical, Inc; Durham, NC)-were compared in a simulated patient model. PPT was associated with multiple aseptic technique violations related to contamination of the syringe barrel. This study confirms the risk of PPT-associated syringe contamination and suggests that this risk could be mitigated with the use of a protected syringe system, such as LifeFlow.

Short peripheral catheters (SPCs) vary by design and materials. The investigators conducted a before-and-after study comparing catheter dwell time and complications with open and closed system SPCs. Many SPCs in the study were saline locks. Results showed that the closed system SPCs had a significantly longer dwell time than open system SPCs. Complications overall were few and not different between groups. Nurse survey ratings were more positive for reduced blood spillage and materials with the closed system SPC but favored the open system SPC for ease of use when handling the catheter and venipuncture. The most common reason for discontinuing the catheter was for patient discharge.

The use of peripheral implanted ports to administer parenteral nutrition in a number of patient cohorts is increasingly seen as a safe alternative to chest ports with equivalence in long-term outcomes. Two insertion sites on the upper arm were compared using the zone insertion method (ZIM), which was developed as an approach to optimize and reduce catheter-related exit site complications. The ZIM divides the medial upper arm into 3 main colors, red, green, and yellow, which are based on musculoskeletal, skin, and vessel characteristics. The optimal exit site is considered to be the green zone, the middle third of the upper arm. Thirty-five patients were allocated to vein puncture at the yellow/green zone (group A) and 35 patients at the yellow zone near the axilla (group B). All devices were implanted in the distal green zone. Successful peripheral port implantation was 91.4% (n = 35) for group A and 100.0% (n = 35) for group B (P = .07). No procedural or postprocedural complications were observed.

Natalizumab is an effective treatment for multiple sclerosis that requires 4-weekly infusions that are usually provided in hospital outpatient clinics. In this study, a model of care (MOC), an overarching design for the provision of a health care service, was developed to permit home infusions of natalizumab. The proposed new MOC comprised 9 dimensions, in addition to the central concept of patient-centered care at home. The new MOC is responsive to patient needs and prioritizes the nurse-patient therapeutic relationship. It provides practical examples of patient-centered care to guide clinical practice for this patient population in the home setting.

Gammaplex 10% (immune globulin intravenous [human], Bio Products Laboratory, Ltd) can be administered with a 15-minute rate-escalation protocol. This analysis examined safety, patient satisfaction, and cost savings in 49 patients administered Gammaplex 10% via rapid infusion over 11 months. Fourteen patients reported 38 adverse reactions, 37 of which were deemed minor/moderate. Patient satisfaction was very good/outstanding. Infusions were estimated to be 2.4 hours shorter than previously administered intravenous immunoglobulin infusions, saving $151.61 per visit in nursing costs. Rapid infusion of Gammaplex 10% was found to be a safe option to reduce the costs of intravenous immunoglobulin treatment while maintaining patient satisfaction.

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.

Nursing practice and institutional policies regarding short peripheral catheter (SPC) flushing vary. These variations result in a lack of understanding about the factors that influence nurses' SPC flushing practices and leave their effect on outcomes unexplored-information that could potentially enhance nurses' clinical education, institutional policy efforts, and patient care. Using a mixed-methods design, this study examined SPC flushing practices and outcomes among a cohort of medical-surgical nurses and explored their rationale for flushing. Trends were noted in the timing of flushes, and the factors that influenced nurses' SPC flushing practices included patient acuity, experience, and workload.

This prospective, comparative study examined blood test results, hemolysis rates, and patient perceptions related to 2 blood sampling methods in pediatric inpatients (N = 95). Blood specimens were drawn via venipuncture and a short peripheral catheter used for fluid administration. Results revealed no significant differences in potassium and glucose levels. No clinically significant difference in hemoglobin was noted. Hemolysis rates were 4% for venipuncture samples and 15% when drawn from peripheral catheters. One catheter became occluded after a blood draw. Patients/parents rated distress and dissatisfaction with venipuncture as significantly greater compared with short peripheral catheter blood sampling (P < .001).
