Peripheral Venous Catheter-related Bloodstream Infections in Hospitalized Children: The Role of Gram-negative Bacteria

Factors associated with the disinfection of devices attached to peripheral intravenous catheters performed by the nursing team in pediatric units

Background

Peripheral intravenous catheterization, as well as drug administration through it, represents one of the most performed procedures by the Nursing team and, for that, precautions need to be adopted to offer harm-free care.

Objective

To verify the association of Nursing professionals' work shift and training time with proper disinfection of intravenous catheter devices in pediatric units.

Methods

A cross-sectional and analytical study conducted between June and August 2021 in three hospitalization units of a Pediatric Hospital. The inclusion criterion was drug administration via peripheral intravenous catheters performed by Nursing professionals. The data were analyzed according to inferential statistics, adopting p ≤ .05 as significance level.

Results

There were a total of 385 observations of drug administration procedures. The device was not disinfected in 60.3% of the cases, there was no friction at the suitable time in 86.3%, and the disinfectant was not allowed to dry in 72.5%. The work shift exerted no influence on performance of the disinfection procedure (p = .376). However, longer training time was associated with a lower rate in performing such procedure (p < .001).

Conclusion

Performing friction below the recommended time can cause a false sense of prevention of catheter-associated bloodstream infection; therefore, training sessions and strategies for adherence to the disinfection procedures should be considered, mainly for professionals with more training time.

Care bundle for the prevention of peripheral venous catheter blood stream infections at a secondary care university hospital: Implementation and results

BACKGROUND

Venous catheterization for diagnostic and therapeutic purposes is part of routine hospital practice, as approximately 70% of hospitalized patients have a peripheral venous catheter (PVC). This practice, however, can lead to both local complications, (e.g., chemical, mechanical and infectious phlebitis) and systemic complications (e.g., PVC-related bloodstream infections [PVC-BSIs]). Surveillance data and activities are central to preventing nosocomial infections, phlebitis and improving patient care and safety. The aim of this study was to evaluate the impact of a care bundle on reducing PVC-BSI rates and phlebitis at a secondary care hospital in Mallorca, Spain.

METHODS

Three-phase intervention study targeting hospitalized patients with a PVC. The VINCat criteria were used to define PVC-BSIs and calculate incidence. In phase I (August-December 2015), we retrospectively analyzed baseline PVC-BSI rates at our hospital. In phase II (2016-2017), we conducted safety rounds and developed a care bundle with the goal of reducing PVC-BSI rates. In phase III (2018), we expanded the PVC-BSI bundle to prevent phlebitis and analyzed its impact.

RESULTS

The incidence of PVC-BSIs decreased from 0.48 episodes per 1000 patient-days in 2015 to 0.17 episodes per 1000 patient-days in 2018. The 2017 safety rounds also detected a reduction in phlebitis (from 4.6% of 2.6%). Overall, 680 healthcare professionals were trained in catheter care and five safety rounds were conducted to assess bedside care.

CONCLUSION

Implementation of a care bundle significantly reduced PVC-BSI rates and phlebitis at our hospital. Continuous surveillance programs are needed to adapt measures to improve patient care and guarantee safety.

The efficacy and safety of midazolam with fentanyl versus midazolam with ketamine for bedside invasive procedural sedation in pediatric oncology patients: A randomized, double-blinded, crossover trial

Children with cancer often require sedation before undergoing invasive procedures. Fentanyl, ketamine, and midazolam are effective drugs widely used for procedural sedation. This study aimed to investigate the efficacy and safety of midazolam-fentanyl (M-F) compared with midazolam-ketamine (M-K) for bedside procedural sedation among pediatric oncology patients. A randomized, double-blinded, crossover trial was conducted among children with cancer requiring procedural sedation for invasive procedures. Patients were randomly assigned either intravenous M-F or M-K and subsequently received the alternate regimens following the crossover design of the study. The efficacy and safety of the sedations including sedation time intervals, nausea score, vomiting episodes, pain score, adverse effects, and parent's satisfaction were evaluated. In all, 58 patients with 116 procedural sedations were enrolled. M-K provided a shorter induction time (0:58 vs. 1:23 min) (p = 0.005), but longer sedation (9:02 vs. 5:50 min) (p = 0.019) and emergence time (4:26 vs. 0:56 min) (p = 0.011) compared with M-F. Sedation routes affected the sedation time intervals. Patients had higher rates of vomiting (0, range 0-8 vs. 0, range 0-2) (p = 0.033) but experienced less pain (0 vs. 2) (p = 0.008) in the M-K group. Overall satisfaction and other adverse effects were comparable among both sedation regimens. Combined sedative drugs are recommended to improve the effectiveness of bedside procedural sedation. M-K provided shorter induction, but longer sedation and emergence time compared with M-F. These findings correlated with sedative routes. Patients receiving M-K experienced a higher rate of vomiting, but less painfulness compared with M-F. Overall satisfaction and tolerable side effects were comparable among both sedative regimens.
