Health Care–Associated Infection in the Pediatric Intensive Care Unit

INJEX50 could improve the success rate of local anesthesia for arterial cannulation in the pediatric intensive care unit: A randomized, double-blind, single-center study

BACKGROUND

Quick arterial cannulation is required in pediatric emergency situation, which require effective local anesthesia to avoid withdrawal movement. However, pediatric local anesthesia could be difficult because of withdrawal movement. Jet injectors, which are needleless and provide local anesthesia quickly, could be helpful for pediatric local anesthesia during arterial cannulation.

AIMS

This study aimed to examine whether new jet injector "INJEX50" could improve the success rate of local anesthesia for arterial cannulation in pediatric intensive care unit compared with the current standard of care, infiltration using a 26-gauge needle.

METHODS

This study was a randomized, double-blind, single-center study. Participants were infants and young children in the pediatric intensive care unit, who required an arterial line. Local anesthesia was performed with either a 26-gauge needle (group C) or INJEX50 (group I) before arterial cannulation. The primary outcome (success of local anesthesia) was the presence of withdrawal movement at the time of skin puncture for arterial cannulation. The secondary outcomes included rescue sedation during arterial cannulation. Data were analyzed using Fisher's exact test and the Mann-Whitney U-test, with values of p < .05 considered statistically significant.

RESULTS

Seventy patients were randomly assigned to groups C and I. The local anesthesia success rate in group I (30/35 [86%]) was significantly higher than that in group C (15/35 [43%], odds ratio, 8.00; 95% confidence interval, 2.51-25.5; p = .0005). In conclusion, INJEX50 could improve success rate of local anesthesia for arterial cannulation in pediatric intensive care unit compared with 26-gauge needle.

Short-duration selective decontamination of the digestive tract infection control does not contribute to increased antimicrobial resistance burden in a pilot cluster randomised trial (the ARCTIC Study)

OBJECTIVE

Selective decontamination of the digestive tract (SDD) is a well-studied but hotly contested medical intervention of enhanced infection control. Here, we aim to characterise the changes to the microbiome and antimicrobial resistance (AMR) gene profiles in critically ill children treated with SDD-enhanced infection control compared with conventional infection control.

DESIGN

We conducted shotgun metagenomic microbiome and resistome analysis on serial oropharyngeal and faecal samples collected from critically ill, mechanically ventilated patients in a pilot multicentre cluster randomised trial of SDD. The microbiome and AMR profiles were compared for longitudinal and intergroup changes. Of consented patients, faecal microbiome baseline samples were obtained in 89 critically ill children. Additionally, samples collected during and after critical illness were collected in 17 children treated with SDD-enhanced infection control and 19 children who received standard care.

RESULTS

SDD affected the alpha and beta diversity of critically ill children to a greater degree than standard care. At cessation of treatment, the microbiome of SDD patients was dominated by Actinomycetota, specifically Bifidobacterium, at the end of mechanical ventilation. Altered gut microbiota was evident in a subset of SDD-treated children who returned late longitudinal samples compared with children receiving standard care. Clinically relevant AMR gene burden was unaffected by the administration of SDD-enhanced infection control compared with standard care. SDD did not affect the composition of the oral microbiome compared with standard treatment.

CONCLUSION

Short interventions of SDD caused a shift in the microbiome but not of the AMR gene pool in critically ill children at the end mechanical ventilation, compared with standard antimicrobial therapy.

Challenges to infection control in early communication intervention: A scoping review

Background: Personal protective equipment (PPE) and infection prevention and control (IPC) measures are crucial to preventing the spread of coronavirus disease 2019 (COVID-19). This study used a scoping review to investigate the challenges that exist when speech–language therapists (SLTs) use IPC measures for providing early communication intervention (ECI).Objectives: To describe existing, recent literature on PPE and IPC measures used in early intervention through a scoping review (steps 1–5) and to consult local clinicians to investigate how SLTs who provide ECI in South Africa relate to these findings (step 6 of the scoping review).Method: A scoping review was performed which followed the PRISMA-ScR framework. Because of limited literature on PPE and IPC measures used by SLTs in providing ECI, the inclusion criteria were adjusted to include PPE and IPC measures used by healthcare workers (HCWs) who provide early intervention to the population of infants and toddlers up to 3 years old. At the time of the review, articles were not older than 10 years and were published between 2011 and 2020. The scoping review included a consultation with South African SLTs who provide ECI, including during the COVID-19 pandemic. A pilot study was conducted prior to the consultations. Seventeen clinicians were included in total. Data from both the pilot study and main consultation were transcribed and analysed in the results using thematic analysis.Results: Fourteen articles were included in the study. The scoping review of existing literature identified challenges to implementing IPC measures, namely the care and behaviour of young children, infrastructure and system challenges, poor compliance and lack of training and a lack of standard IPC protocols. Clinicians in the consultation phase confirmed these challenges and reported that IPC measures did not consider ECI populations nor the settings in which services were provided. Suggestions from the literature for improved infection control included hand hygiene, improved supplies and infrastructure and education and training. Clinicians in the consultation added practical suggestions for implementing IPC measures within ECI, which included an increase in parent-led intervention as well as cleaning and disinfection strategies.Conclusion: This study identified challenges and recommendations of SLTs who use PPE and IPC measures whilst providing ECI. Understanding these challenges can benefit ECI services and future research efforts focused on improving ECI services whilst maintaining IPC standards.

Impact of dry hydrogen peroxide on hospital-acquired infection at a pediatric oncology hospital

BACKGROUND

This study aims to describe the effect of Dry Hydrogen Peroxide (DHP), as an adjunct to environmental cleaning and disinfection, on the incidence of hospital-acquired infections (HAIs) at Unidad Nacional de Oncologia Pediatrica (UNOP) in Guatemala City, Guatemala.

METHODS

A retrospective study of all HAI data from the hospital's surveillance system, which follows Centers for Disease Control and Prevention (CDC) protocols, was conducted from January 2019 to November 2020. DHP was installed in all Pediatric Intensive Care Unit (PICU) rooms in January 2020, but nowhere else in the hospital, including the Intermediate Care Unit (IMCU).

RESULTS

There were 189 HAI cases during the study period, with 173 occurring in either the PICU or IMCU. A statistically significant decrease in HAI incidence rates occurred in the PICU in 2020 compared to 2019 (P = .028), including Clostridiodes-associated gastroenteritis (P = .048). Logistic multivariate regression yielded a significant association between DHP exposure and reduced odds of developing an HAI during the study (OR = 0.3857, P = .029).

CONCLUSION

The use of DHP as an adjunct technology for environmental cleaning and disinfection contributed to the reduction in HAIs in the PICU. Our study highlights the value of such an approach as an addition to manual cleaning to decrease the risk of infection from environmental contamination.
