Late presenting nasal deformities after nasal continuous positive airway pressure injury: 33-year experience

Reporting nasal pressure injuries in neonates receiving non-invasive ventilation: a scoping review

BACKGROUND/OBJECTIVES

Although neonates receiving Non-Invasive Ventilation (NIV) for respiratory support are at risk for nasal pressure injuries, efforts to standardize reporting are limited. A scoping review was conducted to identify the reporting systems used for describing these injuries.

SUBJECTS/METHODS

PubMed, Embase, and Web of Science were queried for papers reporting nasal injury with NIV usage in neonates. The primary outcome was reporting system usage.

RESULTS

705 titles and abstracts were screened. 40 papers met inclusion criteria. Most studies were Randomized Clinical Trials (37.5%) or cohort studies (37.5%). Most commonly, nasal injuries were reported using a unique, descriptive scale developed by the authors (10 studies, 25%). The Fischer et al 2010 scale, a three-stage reporting system, was used in 8 studies (20%). While 15 studies (38.0%) reported on specific anatomic subsite injury, only 2 studies (5.0%) employed endoscopy for assessment.

CONCLUSIONS

Wide heterogeneity in pressure injury reporting secondary to NIV exists across specialties, institutions, and literature.

French Neonatal Society issues recommendations on preventing nasal injuries in preterm newborn infants during non-invasive respiratory support

AIM

To issue practical recommendations regarding the optimal care of nasal skin when non-invasive ventilation support is used.

METHODS

We performed a systematic search of PubMed to identify relevant papers published in English or French through December 2019. Different grades of evidence were evaluated.

RESULTS

Forty-eight eligible studies. The incidence in preterm infants was high. The lesions were more frequent for preterm infants born under 30 weeks of gestational age and/or below 1500 g. The lesion was most often located on the skin of the nose but could also be found on the intranasal mucous membranes or elsewhere on the face. Nasal injuries appear early after the beginning of non-invasive ventilation at a mean of 2-3 days for cutaneous lesions and eight or nine for intranasal lesions. The most effective strategies to prevent trauma are the use of a hydrocolloid at the beginning of the support ventilation, the preferential use of a mask and the rotation of ventilation interfaces.

CONCLUSION

Nasal injuries with continuous positive airway pressure treatment in preterm newborn infants were frequent and can induce pain, discomfort and sequelae. The immature skin of preterm newborn infants needs specific attention from trained caregivers and awareness by parents.

Satisfaction of Health Professionals Regarding the Short Binasal Prong Used as a Non-Invasive Ventilation Interface in Neonatology

Purpose

To evaluate the health professionals' satisfaction regarding the short binasal prong used in Neonatal Intensive Care Units (NICU), evaluate the difficulties related to its use, and present possible improvements in the design of this device.

Patients and Methods

Observational, cross-sectional study with prospective data collection carried out in the NICU of a public hospital in southern Brazil. This research was presented into two stages. In the first stage, the Quebec User Evaluation of Satisfaction with Assistive Technology was applied with 90 health professionals to evaluate the satisfaction regarding the short binasal prong. In the second stage, the health professional's experiences and difficulties in using the binasal prongs in 14 newborns (NBs) that required non-invasive ventilation was collected. The short binasal prongs used was the Fanem® brand and the CPAP circuit was Gabisa Medical International (GMI®). Finally, improvements and recommendations were presented to optimize the device's design.

Results

The mean score of the health professionals' satisfaction with short binasal prongs was 3.8 ± 0.6. Ease of adjustment (3.27) and dimensions (3.62) variables had the worst scores. The main difficulties pointed out by health professionals were: circuit disconnection (57.1%), the size of the prong did not correspond to NBs' anatomical characteristics (35.7%), air leakage (21.4%), and difficulty in fixing and positioning the prong in the NB (14.28%). The improvements suggested were: appropriate prong sizes based on the anatomical characteristics of the NBs; adjustable distance between insertion and base catheters; manufactured with malleable material, however not easily foldable; curved and adjustable insertion catheters and functional system of tracheas' connection.

Conclusion

The dissatisfaction of health professionals with the dimensions and prongs adjustments and the difficulties faced in clinical practice indicate the need for improvements in these interfaces. The recommendations presented in this study may contribute to optimizing the design of the binasal prong in the future.

Systematic rotation versus continuous application of 'nasal prongs' or 'nasal mask' in preterm infants on nCPAP: a randomized controlled trial

To compare whether alternate rotation of nasal mask with nasal prongs every 8 h as compared to continuous use of either interface alone decreases the incidence of nasal injury in preterm infants receiving nasal Continuous Positive Airway Pressure (nCPAP). This was an open-label, three-arm, stratified randomized controlled trial where infants < 35 weeks receiving nCPAP were randomized into three groups using two different nasal interfaces (continuous prongs group, continuous mask group, and rotation group). All infants were assessed for nasal injury six hours post-removal of nCPAP using grading suggested by Fischer et al. The nursing care was uniform across all three groups. Intention-to-treat analysis was done. Fifty-seven infants were enrolled, with nineteen in each group. The incidence of nasal injury was 42.1% vs. 47.4% vs. 68.4% in the rotation group, continuous mask, and continuous prongs groups, respectively (P = 0.228). On adjusted analysis (gestational age, birth weight, and duration of nCPAP therapy), the incidence of nasal injury was significantly less in the rotation group as compared to continuous prongs group (Adjusted Odds Ratio [AOR], 95% confidence interval [CI]; 0.10 [0.01-0.69], P = 0.02) and a trend towards lesser nasal injury as compared to continuous mask group (AOR, 95% CI; 0.15 [0.02-1.08], P = 0.06). However, there was no significant difference in incidence of nasal injuries between continuous prongs versus continuous mask group (P = 0.60). The need for surfactant, nCPAP failure rate, duration of nCPAP, and common neonatal co-morbidities were similar across all three groups.   Conclusion: Systematic rotation of nasal mask with nasal prongs significantly reduced nasal injury among preterm infants on nCPAP as compared to continuous use of nasal prongs alone without affecting nCPAP failure rate.   Trial registration: CTRI/2019/01/017320, registered on 31/01/2019. What is Known: • Use of nasal mask as an interface for nasal Continuous Positive Airway Pressure decreases nasal injury as compared to nasal prongs. What is New: • Rotation of nasal prongs and nasal mask interfaces alternately every 8 h may reduce the nasal injury even further as compared to either interface alone.

Incidence of nasal pressure injury in preterm infants on nasal mask noninvasive ventilation

OBJECTIVE

The aim of this study was to evaluate the incidence of nasal injury in preterm newborns (NB) using the Neonatal Skin Condition Score within 7 days of noninvasive ventilation (NIV) and to compare the incidence of injury in NB weighing ≥1,000 g and those weighing <1,000 g at the time of initiation of NIV support.

METHODS

This is a prospective, observational study carried out in a neonatal intensive care unit of a public hospital in Rio Grande do Sul from July 2016 to January 2021. Patients were stratified into two groups at the time of NIV initiation: group 1 (weight ≥1,000 g) and group 2 (weight <1,000 g). To assess the condition of nasal injury, a rating scale called the Neonatal Skin Condition Score was applied during the first seven consecutive days on NIV. Kaplan-Meier, log-rank test, and Cox proportional hazards regression were used to estimate the hazard ratio (HR) and 95% confidence interval (CI).

RESULTS

In total, 184 NB were evaluated. Nasal injury was reported in 55 (30%) NB. The risk of nasal injury was 74% higher in group 2 (19/45) than in group 1 (36/139) (HR: 1.74; 95%CI 0.99-3.03, p=0.048).

CONCLUSION

The incidence of nasal injury in infants submitted to NIV by nasal mask was high, and the risk of this injury was greater in preterm infants weighing <1,000 g.

Hospital-acquired skin lesions in the neonatal intensive care unit: A retrospective analysis of temporal trends and quality improvement strategies

PURPOSE

Skin lesions in neonatal population are an emerging problem deserving attention from health care professionals. The purpose of this study is to retrospectively assess the incidence of hospital-acquired skin lesions during a 6-year period and to describe the characteristics of infants who developed them.

DESIGN AND METHODS

This was a retrospective observational study conducted in a university-tertiary care center between 2015 and 2020. A descriptive analysis of the observed skin lesions is presented according to 2 time periods: 1) the implementation phase of a quality improvement program (2015-2019) and 2) the postimplementation phase (2020).

RESULTS

Our findings showed an apparent increase in the incidence of all reported skin lesions throughout the study period. Pressure injuries were the most frequently reported skin lesions showing an increasing incidence over time which, however, was paralleled by a reduction in their severity. Among pressure injuries, device-related injuries were the most commonly observed (56.6% and 62.5% in the two periods, respectively) with nasal continuous positive airway pressure-related injuries accounting for 71.7% and 56.0% of lesions, respectively, and mainly affecting the nose root. The occipital area was the most frequently involved site in cases of conventional pressure injuries.

CONCLUSION

Infants admitted to Neonatal Intensive Care Units may be at high risk of developing skin lesions. The adoption of appropriate preventative as well as treatment interventions could be effective in reducing the severity of pressure injuries.

PRACTICE IMPLICATIONS

The implementation of quality improvement strategies may contribute to prevent skin injuries or lead to their early detection.

Facial Soft Tissue Injuries in Pediatric Patients

Soft tissue injuries of the head and neck are a common reason for medical evaluation and treatment in pediatric populations with some unique and important considerations when compared with adults. The incidence and type of injuries continue to evolve with the adoption of new safety measures, technology advancements, and education of the general population. The goal of this article is to provide the reader with a thorough understanding of the evaluation and management of pediatric soft tissue trauma including the initial workup, physical examination, appropriateness of antimicrobial therapy, and setting for surgical repair. Additionally, the pediatric anesthetic considerations for evaluation and repair in regard to local anesthesia, sedation, and general anesthesia are described in detail. There is a focus on dog bites, perinatal injuries, and child abuse as these entities are distinctive to a pediatric population and have particular management recommendations. Lastly, application of the reconstructive ladder as it applies to children is supported with specific case examples and figures. Although there are many parallels to the management of soft tissue injury in adults, we will highlight the special situations that occur in pediatric populations, which are imperative for the facial plastic and reconstructive surgeon to understand.

Incidence and Severity of Nasal Injuries in Preterm Infants Associated to Non-Invasive Ventilation Using Short Binasal Prong

Short binasal prongs can cause skin and mucosal damage in the nostrils of preterm infants. The objective of this study was to investigate the incidence and severity of nasal injuries in preterm infants during the use of short binasal prongs as non-invasive ventilation (NIV) interfaces. A prospective observational study was carried out in the public hospital in a Southern Brazil. The incidence and severity of internal and external nasal injuries were evaluated in 28 preterm infants who required NIV using short binasal prongs for more than 24 hours. In order to identify possible causes of those nasal injuries, the expertise researcher physiotherapist has been carried empirical observations, analyzed the collected data, and correlated them to the literature data. A cause and effect diagram was prepared to present the main causes of the nasal injury occurred in the preterm infants assessed. The incidence of external nasal injuries was 67.86%, and internal ones 71.43%. The external nasal injuries were classified as Stage I (68.42%) and Stage II (31.58%). All the internal injuries had Stage II. The cause and effect diagram was organized into 5 categories containing 17 secondary causes of nasal injuries. There was a high incidence of Stage II-internal nasal injury and Stage I-external nasal injury in preterm infants submitted to NIV using prongs. The injuries genesis can be related to intrinsic characteristics of materials, health care, neonatal conditions, professional competence, and equipment issues.

Application of Autologous Cartilage Transplantation in the Reconstruction of Congenital Nasal Soft Triangle Deformities in Asians

BACKGROUND

Nasal soft triangle is one of the areas usually left unattended in most rhinoplasties, whereas its unique anatomy puts it at great risk of deformities. Its appearance is critical to the natural contour of the nasal tip lobule. The purpose of this study was to evaluate the outcome of autologous cartilage transplantation in treating congenital nasal soft triangle deformities in Asians.

METHODS

From January 2016 to January 2018, 32 patients underwent the procedure, in which costal cartilage, septal cartilage, or conchal cartilage was taken. All cases were operated upon using the external rhinoplasty approach. The cartilage was carved into battens as the lateral and intermediate crura grafts to reconstruct the dome of alar cartilage and treat the soft triangle deformities. The costal cartilage or septal cartilage was used as a columella strut. At the same time, a prosthesis or costal cartilage scaffold was placed onto the nasal dorsum, and finally the fascia was placed on the tip of the nose to relieve tension. The changes of the angle between the intermediate and lateral crura of the alar cartilage before and after cartilage graft and the difference between the greatest distance from the long axis of the nostrils to the alar rim before and after surgery were statistically analyzed. In addition, we compared the preoperative and postoperative nasal contour and evaluated the outcome of soft tissue triangle deformities and asymmetry correction and the whole procedure.

RESULTS

The angle between the lateral and medial crura of the 32 patients decreased from 51.5 ± 10.9 degrees preoperatively to 37.2 ± 5.9 degrees at completion of the nasal dome reconstruction (P < 0.05). The maximum distance from the long axis of the nostrils to the alar rim was 3.3 ± 0.6 mm preoperatively and 1.9 ± 0.7 mm postoperatively (P < 0.05). The patients were followed up for 6 to 18 months, and the noses were with natural contour and tactile impression and without any serious complications. The degree of satisfaction was 87.5%.

CONCLUSIONS

The application of autologous cartilage is an ideal choice to treat soft triangle deformities, which can result in significant improvement of the nasal contour and high degree of satisfaction postoperatively.

Development of anatomical nasal protector for newborns using prongs

OBJECTIVE

To develop an anatomical nasal protector for newborns using prongs.

METHOD

A descriptive study and technological production based on the Product Development Process, which involved informational design, conceptual design and detailed design phases, between March 2017 and February 2019.

RESULTS

The design and materialization of nasal protectors were achieved in hydrocolloid plates. These were reprocessed by five sterilization methods: ultraviolet and gamma radiation, gaseous formaldehyde, hydrogen peroxide plasma and saturated steam under pressure. Microbiological tests indicated bacterial growth after processing by formaldehyde and ultraviolet radiation. Gamma radiation guaranteed the sterility and stability of the material.

CONCLUSION

Three classifications of nasal hydrocolloid protectors were achieved after the tests, with safe and promising characteristics to continue studies aiming at the clinical evaluation in newborns using prongs.

Hydrocolloid versus silicone gel for the prevention of nasal injury in newborns submitted to noninvasive ventilation: A randomized clinical trial

Purpose

To compare the effectiveness of the hydrocolloid and the silicone gel on the nasal protection of the newborns (NBs) during the use of noninvasive ventilation (NIV).

Materials and methods

Thirty-three NBs were selected. They were randomly divided into three groups of 11 NBs, according to the type of nasal protection used: hydrocolloid, thick silicone gel, and thin silicone gel. The stage of the nasal injury and need for exchanging nasal protection were assessed before the connection to the NIV and every 24 h until the physician's authorization for NIV's suspension.

Results

The mean gestational age was 32.03 ± 3.93 weeks, and the median birth weight was 1760 g (750–3535 g). The incidence of nasal injury using hydrocolloid, thick silicone gel, and a thin silicone gel group was 36.36%, 81.81%, and 72.72%, respectively (p = 0.06). Regarding the injury stage, there was no statistical significance between the three study groups. The hydrocolloid protection type had the best adhesion (p = 0.03) on the NBs' skin.

Conclusions

Although this study was conducted by local practice patterns, the results showed that the hydrocolloid could be the best choice to prevent the nasal septum base injury in the NB submitted to NIV.

A Randomized Controlled Trial of a Barrier Dressing to Reduce Nasal Injury in Preterm Infants Receiving Binasal Noninvasive Respiratory Support

OBJECTIVE

To determine whether the use of a hydrocolloid nasal barrier dressing during binasal continuous positive airway pressure (CPAP) therapy, compared with no barrier dressing, reduces the rate of nasal injury in very preterm and/or very low birth weight infants.

STUDY DESIGN

A single-center randomized controlled trial conducted in the neonatal intensive care unit at The Royal Women's Hospital, Melbourne. Eligible infants were born <30 weeks of gestation and/or with birth weight <1250 g, and had received ≥4 hours, but <48 hours, of CPAP. Infants were randomly allocated to receive either a hydrocolloid nasal barrier dressing during CPAP (barrier group), or no barrier dressing (no barrier group). The primary outcome was the incidence of any nasal injury during CPAP support, until the infant was both >30 weeks of postmenstrual age and >1250 g, unless CPAP therapy was stopped earlier. Nasal injury was regularly assessed by bedside nurses using a standardized form.

RESULTS

A total of 108 preterm infants were enrolled: 53 infants in the barrier group and 55 infants in the no barrier group. Infants in the barrier group had a significantly lower rate of nasal injury compared with the no barrier group: 18 of 53 (34%) vs 31 of 55 (56%), respectively (P = .02), number needed to treat; 5 infants. No significant differences were detected in any secondary respiratory outcomes, or in the rate of common neonatal morbidities.

CONCLUSIONS

Prophylactic use of a nasal barrier dressing within 48 hours of commencing treatment with binasal CPAP in very preterm or very low birth weight infants reduces nasal injury.

V-shaped Internal Nasal Vestibular Flap for Reconstruction of Iatrogenic Columellar Defect

Columella is an important structure in the center of the face, and its structural integrity has an important functional, social, and psychological role. Columella reconstruction can be very challenging for surgeons and the ideal technique remains elusive. This article describes a reconstruction technique in a young woman with columella necrosis due to nasal continuous positive airway pressure treatment. The method of reconstruction described here, with a V-shaped internal nasal vestibular flap and a cartilage grafts from lateral crura, is simple and easily reproducible, providing an optimal aesthetic result and in addition the donor site does not create a secondary deformity by disrupting normal anatomy.

Nasal injury in preterm infants receiving non-invasive respiratory support: a systematic review

OBJECTIVE

Binasal prongs are the most commonly used interface for the delivery of nasal positive airway pressure (CPAP) to preterm infants. However, they are associated with pressure-related nasal injury, which causes pain and discomfort. Nasal injury may necessitate a change in interface and occasionally damage is severe enough to require surgical repair. We aim to determine the incidence and risk factors for nasal injury in preterm infants, and to provide clinicians with strategies to effectively prevent and treat it.

DESIGN

We conducted a systematic search of databases including MEDLINE (PubMed including the Cochrane Library), EMBASE, CINAHL and Scopus. Included studies enrolled human preterm infants and were published prior to 20 February 2017.

RESULTS

Forty-five studies were identified, including 14 ra ndomised controlled trials, 10 observational studies, two cohort studies, eight case reports and 11 reviews. The incidence of nasal injury in preterm infants ranged from 20-100%. Infants born <30 weeks' gestation are at highest risk. Strategies shown to reduce nasal injury included: nasal barrier dressings (2 studies, n=244, risk ratio (RD) -0.12, 95%, CI - 0.20 to -0.04), nasal high flow therapy as an alternative to binasal prong CPAP (7 studies, n=1570, risk difference (RD) -0.14, 95% CI -0.17 to -0.10), and nasal masks rather than binasal prongs (5 studies, n=544, RR 0.80, 95% CI 0.64 to 1.00).

CONCLUSIONS AND RELEVANCE

Nasal injury is common in preterm infants born <30 weeks' gestational age receiving CPAP via binasal prongs. Larger randomised trials are required to fully evaluate strategies to reduce nasal injury.

[Scar revision in children: Clinical situations and solutions]

The scar of soft tissues is a permanent stigma of a trauma but it can sometimes be improved. It is more or less accepted by the patient and may be the source of a significant physical and psychosocial impact that leads to a request for a scar revision. Even if the child presents generally an excellent ability to heal, the quality of the scar depends on many factors such as the age, the type of scar or trauma and the affected body area. Thus, its aesthetic impact, functional but also on the growth of the child will be different. Moreover, these scars have a number of origins: neonatal surgery, natural history of congenital lesions or after a surgical management; surgeries for orthopedic, cardiac, craniofacial or hand birth defects and congenital malformations; or infectious or traumatic as in the case of burns and animal bites. We have many ways to try to correct or improve these scars, which use all the plastic surgery techniques. However, we need to establish for each case an appropriate management strategy with the objective of not inducing additional sequelae, respecting the growth of the child. Several techniques can be combined and the chronology of the surgical procedures must consider the school, social and family integration of the child.

Safety and Efficacy of High-Flow Nasal Cannula Therapy in Preterm Infants: A Meta-analysis

BACKGROUND AND OBJECTIVE

High-flow therapy is the most recent, and popular, mode of respiratory support in neonates. However, the evidence supporting its efficacy and safety has not yet been established. We conducted a systematic review and meta-analysis of clinical trials comparing efficacy and safety of high-flow therapy compared with other modes of noninvasive ventilation (NIV) in preterm infants.

METHODS

Articles were indexed by using Medline, Embase, Scopus, OpenSIGLE, Health Management Information Consortium, and Cochrane Central Register of Controlled Trials. Randomized or quasi-randomized clinical trials involving preterm infants, comparing high-flow therapy with other modes of NIV, and reporting extractable data on relevant outcomes, were selected. Data on efficacy, safety, and other common neonatal outcomes were extracted on predesigned forms.

RESULTS

In this analysis, we included 1112 preterm infants, participating in 9 clinical trials. High-flow therapy was similar in efficacy to other modes of NIV in preterm infants when used as primary support (odds ratio of failure of therapy, 1.02 [95% confidence interval: 0.55 to 1.88]), as well as after extubation (1.09 [0.58 to 2.02]). There were no significant differences in odds of death (0.48 [0.18 to 1.24]) between the groups. Preterm infants supported on high-flow had significantly lower odds of nasal trauma (0.13 [0.02 to 0.69]).

CONCLUSIONS

High-flow therapy appears to be similar in efficacy and safety to other conventional modes of NIV in preterm infants. It is associated with significantly lower odds of nasal trauma. Caution needs to be exercised in extreme preterm infants because of the paucity of published data.
