Saline irrigation for the management of skin extravasation injury in neonates

Extravasation Injuries of the Limbs in Neonates and Children-Development of a Treatment Algorithm

BACKGROUND

Hospitalized children and neonates very often receive intravenous treatment. There has not yet been any systematic study of the incidence of extravasation injuries in this age group. In a few studies of neonates in intensive care receiving intravenous treatment, incidence figures in the range of 18-46% have been reported; 2.4-4% sustain serious complications, such as necrosis and ulceration, that can lead over the long term to contractures, deformities, and impaired limb function due to unfavorable scarring. No guidelines currently exist for the care of pediatric extravasation injuries.

METHODS

This review is based on pertinent publications (from 1979 to June 2020) retrieved by a selective search in PubMed, as well as on experience from the authors' own institution.

RESULTS

In the absence of randomized controlled trials on the care of pediatric extravasation injuries, the available evidence is limited to small-scale comparative studies and case series. Conservative, medical, or surgical treatment can be used, depending on the volume of the extravasate, the nature of the substrate, and individual patient-related factors. It should first be determined whether the extravasated substance has no primary toxic properties or is a tissue irritant or a necrosis-inducing substance (vesicant). The skin and subcutaneous tissue should be examined for injury, coloration, swelling, capillary refill time, and pulses distal to the injury. Depending on the volume of the extravasate, the substrate, and the degree of tissue damage, the injury can be treated conservatively; medically, with the administration of an antidote, hyaluronidase, or a vasodilator such as phentolamine; or surgically, with multiple puncture procedures, washouts, or liposuction.

CONCLUSION

As there is no clear evidence that one form of treatment is superior to any other, the treatment of pediatric extravasation injuries remains an individual decision, with the known attendant risks of off-label treatment.

Treatment of extravasation injuries in infants and young children: a scoping review and survey

BACKGROUND

Extravasation injuries are caused by unintended leakages of fluids or medicines from intravenous lines, but there is no consensus on the best treatment approaches.

OBJECTIVES

To identify which treatments may be best for treating extravasation injuries in infants and young children.

DESIGN

Scoping review and survey of practice.

POPULATION

Children aged < 18 years with extravasation injuries and NHS staff who treat children with extravasation injuries.

INTERVENTIONS

Any treatment for extravasation injury.

MAIN OUTCOME MEASURES

Wound healing time, infection, pain, scarring, functional impairment, requirement for surgery.

DATA SOURCES

Twelve database searches were carried out in February 2017 without date restrictions, including MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature) Plus and EMBASE (Excerpta Medica dataBASE).

METHODS

Scoping review - studies were screened in duplicate. Data were extracted by one researcher and checked by another. Studies were grouped by design, and then by intervention, with details summarised narratively and in tables. The survey questionnaire was distributed to NHS staff at neonatal units, paediatric intensive care units and principal oncology/haematology units. Summary results were presented narratively and in tables and figures.

RESULTS

The evidence identified in the scoping review mostly comprised small, retrospective, uncontrolled group studies or case reports. The studies covered a wide range of interventions including conservative management approaches, saline flush-out techniques (with or without prior hyaluronidase), hyaluronidase (without flush-out), artificial skin treatments, debridement and plastic surgery. Few studies graded injury severity and the results sections and outcomes reported in most studies were limited. There was heterogeneity across study populations in age, types of infusate, injury severity, location of injury and the time gaps between injury identification and subsequent treatment. Some of the better evidence related to studies of flush-out techniques. The NHS survey yielded 63 responses from hospital units across the UK. Results indicated that, although most units had a written protocol or guideline for treating extravasation injuries, only one-third of documents included a staging system for grading injury severity. In neonatal units, parenteral nutrition caused most extravasation injuries. In principal oncology/haematology units, most injuries were due to vesicant chemotherapies. The most frequently used interventions were elevation of the affected area and analgesics. Warm or cold compresses were rarely used. Saline flush-out treatments, either with or without hyaluronidase, were regularly used in about half of all neonatal units. Most responders thought a randomised controlled trial might be a viable future research design, though opinions varied greatly by setting.

LIMITATIONS

Paucity of good-quality studies.

CONCLUSIONS

There is uncertainty about which treatments are most promising, particularly with respect to treating earlier-stage injuries. Saline flush-out techniques and conservative management approaches are commonly used and may be suitable for evaluation in trials.

FUTURE WORK

Conventional randomised trials may be difficult to perform, although a randomised registry trial may be an appropriate alternative.

Treating extravasation injuries in infants and young children: a scoping review and survey of UK NHS practice

Background

Extravasation injuries are caused by unintended leakages of fluids or medicines from intravenous lines but there is no consensus on the best treatment approaches, particularly in infants and young children.

Methods

This paper presents a more succinct account of a study of treatments for extravasation injuries in infants and children which has also been reported in full as an NIHR HTA report. A systematic scoping review and survey of UK NHS practice were undertaken. Twelve databases - including MEDLINE and EMBASE - were searched for relevant studies in February 2017. Studies of children with extravasation injuries receiving any treatment for extravasation injury were eligible, providing they reported one of the following outcomes: wound healing time, infection, pain, scarring, functional impairment, and requirement for surgery. Studies were screened in duplicate. Data were extracted by one researcher and checked by another. Studies were summarised narratively. An online questionnaire was distributed to NHS staff at neonatal units, paediatric intensive care units and principal oncology/haematology units.

Results

The evidence identified in the scoping review was mostly comprised of small, retrospective, uncontrolled group studies or case reports. The studies covered a wide range of interventions including conservative management approaches, saline flush-out techniques (with or without prior hyaluronidase), hyaluronidase without flush-out, artificial skin treatments, debridement and plastic surgery. Few studies graded injury severity and the results sections and outcomes reported in most studies were limited. There was heterogeneity across study populations in many factors.

The survey yielded 63 responses from hospital units across the UK. Results indicated that although most units had written documentation for treating extravasation injuries, only one-third of documents included a system for grading injury severity. The most frequently used interventions were elevation of the affected area and analgesics. Saline wash-out treatments, either with or without hyaluronidase, were regularly used in about half of all neonatal units. Most responders thought a randomised controlled trial might be a viable future research design.

Conclusions

There is some uncertainty about which are most the promising treatments for extravasation injuries in infants and young children. Saline flush-out techniques and conservative management approaches are commonly used and may be suitable for evaluation in trials. Although conventional randomised trials may be difficult to perform a randomised registry trial may be an appropriate alternative design.

Contrast media extravasations in patients undergoing computerized tomography scanning: a systematic review and meta-analysis of risk factors and interventions

OBJECTIVE

To identify risk factors and interventions preventing or reducing contrast medium extravasation.

INTRODUCTION

Computed tomography (CT) is a radiological examination essential for the diagnosis and monitoring of many diseases. It is often performed with the intravenous (IV) injection of contrast agents. Use of these products can result in a significant complication, extravasation, which is the accidental leakage of IV material into the surrounding tissue. Patients may feel a sharp pain and skin ulceration or necrosis may develop.

INCLUSION CRITERIA

This review considered studies that included patients (adults and children) undergoing a CT with IV administration of contrast media. The risk factors considered were patient demographics, comorbidities and medication history. This review also investigated any strategies related to: contrast agent, injection per se, material used for injection, apparatus used, healthcare professionals involved, and patient risk assessment performed by the radiology personnel. The comparators were other interventions or usual care. This review investigated randomized controlled trials and non-randomized controlled trials. When neither of these were available, other study designs, such as prospective and retrospective cohort studies, case-control studies and case series, were considered for inclusion. Primary outcomes considered were: extravasation frequency, volume, severity and complications.

METHODS

The databases PubMed, CINAHL, Embase, the Cochrane Register of Controlled Trials, Web of Science PsycINFO, ProQuest Dissertations and Theses A&I, TRIP Database and ClinicalTrials.gov were searched to find both published and unpublished studies from 1980 to September 2016. Papers were assessed by two independent reviewers for methodological validity using the Joanna Briggs Institute System for the Unified Management, Assessment and Review of Information (JBI SUMARI). Data were extracted using the standardized data extraction tool from JBI SUMARI. In one case, quantitative data from two cohort studies were pooled in a statistical meta-analysis. However, generally, statistical pooling was not possible due to heterogeneity of the interventions, populations of interest or outcomes. Accordingly, the findings have been presented in narrative form.

RESULTS

Fifteen articles were selected from a total of 2151 unique studies identified. Two were randomized controlled trials and 13 were quasi-experimental and observational studies. The quality of these studies was judged to be low to moderate. Some patient characteristics, such as female sex and inpatient status, appeared to be risk factors for extravasation. Additionally, injection rate, venous access site and catheter dwelling time could affect the volume extravasated. Preliminary studies seemed to indicate the potential of extravasation detection accessories to identify extravasation and reduce the volume extravasated. The other interventions either did not result in significant reduction in the frequency/volume of extravasation, or the results were mixed across the studies.

CONCLUSIONS

The majority of the studies included in this review evaluated the outcomes of extravasation frequency and volume. Given the quality of the primary studies, this systematic review identified only potential risk factors and interventions. It further highlighted the research gap in this area and the importance of conducting trials with solid methodological designs.

Extravasation injuries

It is common for an intravascular catheter to be inserted to administer various types of therapy. Extravasation occurs frequently, and in the most severe cases plastic surgeons are often summoned to assess the extent of the injury and the possibility for reconstruction. The Department of Plastic and Reconstructive Surgery at Oslo University Hospital assesses approximately 15 severe cases of this type each year.

Combined treatment with chlorhexidine and 0·9% saline in a newborn infant with an infected surgical wound

Newborns are more susceptible to infection; this makes proper wound care extremely important in them. Unfortunately, in spite of successful surgery, patients can die as a result of wound area infections. Herein, we report a case in which a combined therapy of chlorhexidine (a disinfectant) and saline (a cleansing agent used in wound care) was used effectively to treat the wound in a newborn infant with an antibiotic-resistant, Gram-negative, bacteria-related surgical site infection.

Neonatal extravasation injury: prevention and management in Australia and New Zealand-a survey of current practice

Background

Extravasation injury remains an important cause of iatrogenic injury in neonatal intensive care. This study aims to describe the current approach to extravasation injury (EI) prevention and management in Neonatal Intensive Care Units (NICUs) in Australia and New Zealand.

Methods

A literature review regarding extravasation injury in the newborn was carried out to inform questionnaire design. An internet-based survey was then conducted with the clinical directors of the 27 tertiary NICUs in Australia and New Zealand.

Results

The survey received a 96% response rate. Approximately two thirds of Australian and New Zealand NICUs have written protocols for prevention and management of extravasation injury. Considerable practice variation was seen for both prevention and treatment of EI. 92% of units had experienced cases of significant EI.

Conclusions

Australian and New Zealand tertiary neonatal units clearly recognise EI as an important cause of iatrogenic morbidity and mortality. Significant variation still exists among units with regards to guidelines for both prevention and management of EI. We recommend that neonatal staff should remain vigilant, ensuring that guidelines for the prevention and treatment of EI are available, and rigorously followed.
