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

Acyclovir extravasation in a newborn: a case report

OBJECTIVE

Extravasation of infused drugs is not a rare problem in medical practice. Acyclovir is a vesicant and an antiviral medication commonly used for young children. In the present study, we presented a neonate with soft tissue damage due to acyclovir extravasation.

CASE REPORT

A female newborn (Iranian, Asian) with gestational age 37+2 weeks and breech presentation was born by Cesarean delivery from a mother with a recent history of Herpes simplex virus (HSV) infection (Yas Women's Hospital, Tehran, Iran). Intravenous administration of acyclovir was initiated through a peripheral catheter inserted on the dorsal side of the left hand. A few minutes after the second dose, the patient showed a diffused firm swelling, local discoloration, and induration in the dorsum of the hand. The peripheral catheter was removed immediately. Hyaluronidase was injected subcutaneously in five different regions around the catheterization site. Intermittent limb elevation and cold compression (for 10 minutes) were applied. Serial follow-ups and examinations were performed hourly to check limb inflammation, ischemia, and compartment syndrome. The limb swelling and discoloration significantly improved 4 hours after the second dose of hyaluronidase.

CONCLUSION

Early diagnosis of acyclovir extravasation and immediate management could prevent severe complications in neonates. Further studies are needed to suggest a standard approach and treatment protocol for acyclovir extravasation.

Phenytoin Induced Purple Glove Syndrome: An Effective Management Technique

Background: Purple glove syndrome (PGS) is a rare condition characterized by limb edema, discoloration, and pain associated with intravenous and oral phenytoin administration. The pathophysiology is poorly understood, and there is no established treatment. Simple cases have previously been managed with hyaluronidase subcutaneous injections, with more severe cases resulting in compartment syndrome, debridement, or even amputation. Methods/Results: In this case report, a 2-year-old boy with status epilepticus developed PGS after receiving intravenous phenytoin via a cannula on the dorsum of the right hand. The patient was successfully managed by locally infiltrating subcutaneous hyaluronidase diffusely to the affected area, titrating its dose to effect, rather than aiming to adhere to any specific dosing limitation. The child was reviewed daily by the Plastic Surgery team until being discharged, and focal lesions began to demarcate after 48 hours, with epidermal loss but no deeper trauma. The epidermis peeled within one month, with healthy underlying skin found underlying when followed up in clinic. Conclusions: This case illustrates that subcutaneous administration of hyaluronidase and titrating to effect provides an effective and safe treatment for treating distal cases of early PGS in children.

When the Going Gets Tough: A Case Report and Review of Calcinosis Cutis in an Infant with Pseudo-Hypoaldosteronism

Calcium gluconate solutions are an essential part of the intensive care medication armamentarium. Calcium-related extravasations are not an infrequent occurrence. However, occult extravasation presenting solely as an isolated mass lesion with no preceding cutaneous manifestation is rare. Calcinosis cutis is an extraosseous collection of calcium deposits in the skin and subcutaneous tissues. Multiple etiopathogenetic factors play a role in its manifestations. We illustrate a case of a seven-week-old infant diagnosed with pseudo-hypoaldosteronism with a mysterious swelling on the left leg during the third week of hospitalization, which was attributed to occult iatrogenic calcinosis cutis.

Sensing Technologies for Extravasation Detection: A Review

Peripheral intravenous catheters are administered for various purposes, such as blood sampling or the infusion of contrast agents and drugs. Extravasation happens when the catheter is unintentionally directed outside of the vein due to movement of the intravascular catheter, enhanced vascular permeability, or occlusion of the upstream vein. In this article, extravasation and its mechanism are discussed. Subsequently, the sensorized devices (e.g., single sensor and multimodal detection) to identify the extravasation phenomena are highlighted. In this review article, we have shed light on both physiological and engineering points of view of extravasation and its detection approaches. This review provides an overview on the most recent and relevant technologies that can help in the early detection of extravasation.

A new approach to skin extravasation injury management during the neonatal period

Background

To identify a standard protocol for managing extravasation injuries in neonates.

Methods

We recruited all the neonates with extravasation wounds from the neonatal intensive care unit of Shariati hospital, Tehran, Iran, between October 2018 and October 2020. Sixteen patients with grade 3–4 extravasation were evaluated in this retrospective study. All grade 3 and 4 extravasation wounds were injected with hyaluronidase at 5 points of the wound circle; the procedure was repeated every 5 min at different points in a smaller circle to the core. The wound was then covered with a warm compress for 24 h. Twenty-four hours after injection, the cover was changed twice a day with normal saline irrigation. Fibrinolysin ointment was applied on top of the wound. The ulcer was then dressed with phenytoin ointment until healing.

Results

Out of 16 neonates who were followed up, 10 of them were male, with the average birth weight being 1.37 (range 1.05–3.75) kg. The mean (± SD) wound healing duration was 13.12 (± 6) (range: 7–29) days. Factors including the cannulation duration before the appearance of the lesion (R:0.2, P = 0.2), birth weight (R = -.37, P = 015), and extravasated substances (p = 0.2) were not associated with the duration of hospital stay. The only exception to this trend is the wound size factor of 7.31(± 7.45) (R = .83, P < 0.001). Continuous and categorical variables were summarized as mean (SD) and proportions, respectively, and the Kruskal–Wallis test and Spearman correlation coefficients were used.

Conclusions

Limited evidence exists on the effects of different protocols on extravasation management in neonates in the NICU. We recommend our method as a standard protocol in NICU for high-stage extravasated lesions because of the shorter duration of healing, non-invasive nature of this procedure, and lack of side effects or surgical involvement.

Case Series of Neonatal Extravasation Injury: Importance of Early Identification and Management

Extravasation injury is a common iatrogenic injury, especially in neonates. Intravenous access is essential in neonatal care, but neonatal extravasation injury is associated with severe morbidity. We present three cases of neonatal extravasation injuries with varying presentations, etiological agents, and timing of management. It shows that extravasation injuries treated with the saline flush-out technique and timely intervention have a superior outcome with almost immediate resolution and subsequent healing with no scars. This is in stark contrast with the lesions treated conservatively with dressings that took more time to heal. We are reminded to be vigilant with infusion therapies and the importance of early detection and prompt treatment in neonatal extravasation injuries.

Precordial Doppler to assess vascular access in children: A preliminary report

BACKGROUND

Delayed identification and dysfunction of peripheral intravenous (PIV) infiltration can lead to serious injury in children. This preliminary study aimed to describe the application of precordial Doppler ultrasound to detect and confirm the correct PIV access in children with congenital heart disease (CHD).

METHODS

This study was conducted on children (<18 years) diagnosed with CHD and admitted to the pediatric intensive care unit (PICU) of a single center after cardiac surgery or cardiac catheterization between February 2020 and May 2021. Three raters judged the precordial Doppler sound change (S test) after injection of 0.5 mL/kg of normal saline (NS) through the PIV access. Blood-flow velocities before and after the NS injection were recorded and the accuracy of detecting PIV catheter infiltration and dysfunction was analyzed (V test).

RESULTS

The overall incidence of PIV infiltration and dysfunction was in 3 out of 103 patients (2.9%). The sensitivity, specificity, positive and negative likelihood ratios, and area under the receiver operating characteristic curve were 3 out of 3 [100%, 95% confidence interval (CI): 29.2-100], 86 out of 100 (86%, 95% CI: 77.6%-92.1), 7.1, 0.0, and 0.93, respectively, in the S test and they were 2 out of 3 (66.7%, 95% CI: 9.4%-99.2), 94 out of 100 (94.0%, 95% CI: 87.4%-7.8%), 11.1, 0.36, and 0.80, respectively in the V test.

CONCLUSIONS

Precordial Doppler ultrasound was a feasible and accurate technique for confirming correct PIV access in children with CHD; however, a larger, prospective investigation is necessary to examine its diagnostic accuracy.

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.

Norepinephrine-Induced Peripheral Ischemia Leading to Gangrene: A Case Series

ABSTRACT

Norepinephrine is used in the acute care setting to establish and maintain hemodynamic stability in patients with hypotension. Although it is often a lifesaving medication, norepinephrine may lead to profound vascular insufficiency in the extremities, resulting in dry gangrene and skin necrosis. The purpose of this article is to present a case series of skin complications related to treatment with norepinephrine and review the pathophysiology behind these complications. The authors also explore risk stratification as it relates to history and clinical presentation with subsequent focus on contingencies to mitigate the adverse effects of vasoconstriction on peripheral tissues.

Medical-Grade Honey for the Treatment of Extravasation-Induced Injuries in Preterm Neonates: A Case Series

INTRODUCTION

Preterm neonates often depend on peripheral intravenous administration of nutrition and medication. Since their skin is not fully developed and very vulnerable, extravasation injury is a risk. Medical-grade honey (MGH) possesses antimicrobial activity and stimulates wound healing; although its use in neonatal patients is limited.

CLINICAL FINDINGS

We present a case series of 7 preterm neonates (28-36 weeks of gestation) with extravasation injuries secondary to peripheral intravenous administration of total parental nutrition and medication.

PRIMARY DIAGNOSIS

Extravasation injury following the unintentional leakage of total parenteral nutrition, and medication into the surrounding tissue. Signs of extravasation include local pain, erythema, burning, pruritus, and/or swelling.

INTERVENTIONS

All extravasation injuries were treated with daily cleaning and application of MGH. Some of the cases needed additional surgical intervention or assisted debridement.

OUTCOMES

After treatment, all extravasation injury wounds presented with granulation tissue formation progressed to normal epithelialization and closed in 7 to 67 days (median: 32 days). Upon initial application, peripheral edema and inflammation decreased. When present, necrotic tissue was effectively debrided, slough was removed, and no signs of infection were detected, irrespective of initial wound presentations. Cicatrization was minimal, and the full range of motion was preserved in all cases.

PRACTICE RECOMMENDATIONS

Continuous and thorough assessment of peripheral intravenous line placement for malposition, leaking, and signs of extravasation is needed for fast discovery and prevention of further damage.

CONCLUSION

Medical-grade honey possesses antimicrobial, anti-inflammatory, and antioxidative activity, enhancing wound healing. Medical-grade honey was safe and effective for treating extravasation-induced injuries, independent of location and severity. We recommend MGH for treating extravasation wounds and consideration for other types of wounds.

Introduction of precordial Doppler ultrasound to confirm correct peripheral venous access during general anesthesia in children: A preliminary study

Background

Delayed identification of infiltration and dysfunction of peripheral intravenous (PIV) access can lead to serious consequences during general anesthesia in children. This preliminary study aimed to describe the application of precordial Doppler ultrasound during general anesthesia in children to detect and confirm the correct PIV access and to evaluate the accuracy of this method.

Methods

This was a single-center, preliminary study that was conducted in children (<18 years) who were scheduled for elective surgeries between October 2019 and March 2020. Rater anesthesiologists judged the change in precordial Doppler sound (S test) before and after injection of 0.5 mL/kg of normal saline (NS) via PIV. Blood flow velocity before and after NS injection was recorded, and multiple cutoff points were set to analyze the accuracy of detecting the infiltration and dysfunction of PIV catheter (V test).

Results

The total incidence of peripheral infiltration and dysfunction of PIV catheter was 7/512 (1.4%). In the S test, the sensitivity, specificity, positive and negative likelihood ratios, and area under the receiver-operating characteristic curves (AUCs) were 5/7 (71.4%; 95% confidence interval [CI], 29.0%–96.3%), 490/505 (97.0%; 95% CI, 95.1%–98.3%), 24.0, 0.29, and 0.84, respectively. The V test showed that the reasonable threshold of blood flow velocity change was 1.0 m/s, with sensitivity, specificity, positive and negative likelihood ratios, and AUC of 4/7 (57.1%; 95% CI, 18.4%–90.1%), 489/505 (96.8%; 95% CI, 94.9%–98.2%), 18.0 and 0.44, and 0.84, respectively.

Conclusions

This preliminary study demonstrated that precordial Doppler ultrasound is a feasible, easy-to-use, and noninvasive technique with good accuracy to confirm the correct PIV access during general anesthesia in children. However, its accuracy requires further evaluation.

Development and evaluation of a technology-enhanced, enquiry-based learning program on managing neonatal extravasation injury: A pre-test/post-test mixed-methods study

BACKGROUND

Extravasation injury remains a significant preventable cause of morbidity and mortality in neonates. Equipping nursing students with the requisite knowledge and skills is essential for appropriate prevention, early detection, and management of extravasation injury.

OBJECTIVES

To develop a technology-enhanced, enquiry-based learning program for nursing students on the prevention and management of neonatal extravasation injury and examine its impact on their knowledge, approaches to studying and experience of learning.

DESIGN

A pre-test/post-test study with qualitative evaluation.

SETTINGS

Two university pre-registration nursing programs in Hong Kong.

PARTICIPANTS

A total of 192 senior-year nursing students.

METHODS

A novel learning program was developed comprising 25 scenario-based video vignettes supplemented with critical-thinking exercises, discussion guides, interactive games, reading materials and a 3-hour in-class interactive workshop. Students received unlimited online access to the program. Data were collected at baseline and one-month post-workshop. Outcomes were students' level of knowledge of prevention and management of extravasation injuries and related care, approaches to studying, and experience of learning. Paired t-tests were performed on pre- post-test outcome data and individual semi-structured interviews were conducted at one-month post-workshop, transcribed verbatim and analyzed thematically.

RESULTS

There were statistically significant improvements in students' level of knowledge and use of a deep approach to learning at one month compared with baseline. Students were highly satisfied with the program, appreciating the video vignettes and interactive small group discussions with academics and clinicians. Suggestions for enhancing the program included more time for the workshop, interaction with clinicians, and details on the administration of neonatal medications and dosages.

CONCLUSIONS

This study showed that a novel technology-enhanced, enquiry-based learning program was effective in enhancing nursing students' knowledge of the prevention and management of neonatal extravasation injury, approaches to studying and experience of learning.

Topical nitroglycerin ointment as salvage therapy for peripheral tissue ischemia in newborns: a systematic review

BACKGROUND

Topical nitroglycerin (TNG) ointment has been used for almost 3 decades to treat neonatal peripheral tissue ischemia, but this product is now no longer being produced by its Canadian manufacturer. Our aim was to investigate the efficacy and safety of TNG products in newborns in neonatal intensive care units.

METHODS

In this systematic review we searched Embase, CINAHL, MEDLINE, PubMed and Web of Science from inception to April 2020 for studies on the use of TNG products (TNG ointment, TNG spray, glyceryl trinitrate [GTN] patch) for the treatment of neonatal tissue ischemia. We did not apply language or study design limitations. Animal studies and duplicate records were excluded. Two reviewers screened and extracted data. The Tool for Evaluating the Methodological Quality of Case Reports and Case Series was used to assess the risk of bias of individual studies.

RESULTS

We included 23 articles (20 case reports, 2 case series and 1 retrospective audit) describing the use of TNG ointment, TNG spray or GTN patch in the treatment of 39 tissue ischemia events in 37 newborns. Twenty-three (62.2%), 12 (32.4%), 1 (2.7%) and 1 (2.7%) infants received TNG ointment, GTN patch, both TNG ointment and GTN patch, and TNG spray, respectively. Nineteen (76.0%) and 7 (53.8%) injuries treated with TNG ointment and GTN patch showed complete recovery, respectively. Two (16.7%) infants treated with GTN patch experienced adverse events (i.e., methemoglobinemia) requiring treatment discontinuation.

INTERPRETATION

TNG ointment presents a safe therapeutic modality for salvage therapy of neonatal tissue ischemia. Engagement of stakeholders is essential to address its recent commercial inaccessibility in Canada.

Upper limb extravasation of cytotoxic drugs: results of the saline washout technique in children

PURPOSE

Extravasation of cytotoxic vesicant drugs is a surgical emergency (within six hours) since this incident can lead to severe skin and soft-tissue damage. Outcomes after the saline washout procedure have been extensively described in adults, but rarely in children. The aim of this study was to evaluate the outcome of early saline washout procedure for upper limb cytotoxic drug extravasation in children.

METHODS

All consecutive children with vesicant drug extravasation were retrospectively reviewed. The saline washout procedure was performed. Cosmetic aspect, residual pain and range of movement were analyzed as well as time to surgery and chemotherapy resumption at last follow-up.

RESULTS

Between 2014 and 2018, 13 cytotoxic vesicant drug extravasations occurred (mean age 8 years (sem 5)), including 11 treated by the saline washout procedure. At mean follow-up of 11 months (sem 7), the patients had no or low pain and ranges of movement were fully conserved. Two patients (one within the six hours' delay) had soft-tissue necrosis leading to extensive reconstructive surgery.

CONCLUSION

The saline washout procedure is safe and easy and significantly reduces the incidence of extensive skin damage. Early referral to a specialized department is essential. However, the key parameter remains prevention by educating medical staff and nurses about these injuries and by training them for early and urgent management.
