Esophago-gastric junction findings on high resolution impedance manometry in children with esophageal atresia.

OBJECTIVES: Using high resolution impedance manometry (HRIM), this study characterized the esophago-gastric junction (EGJ) dynamics in children with esophageal atresia (EA). METHOD: Esophageal HRIM was performed in patients with EA aged less than 18 years. Objective motility patterns were analyzed, and EGJ data reported. Controls were pediatric patients without EA undergoing investigations for consideration of fundoplication surgery. RESULTS: Seventy-five patients (M:F = 43:32, median age 1 year 3 months [3 months-17 years 4 months]) completed 133 HRIM studies. The majority (64/75, 85.3%) had EA with distal tracheo-esophageal fistula. Compared with controls, liquid swallows were poorer in patients with EA, as evident by significant differences in distension pressure emptying and bolus flow time (BFT). The integrated relaxation pressure for thin liquid swallows was significantly different between EA types, as well as when comparing patients with EA with and without previous esophageal dilatations. The BFT for solid swallows was significantly different when compared with EA types. CONCLUSIONS: We have utilized HRIM in patients with EA to demonstrate abnormalities in their long-term EGJ function. These abnormalities correlate with poorer esophageal compliance and reduced esophageal peristalsis across the EGJ. Understanding the EGJ function in patients with EA will allow us to tailor long-term management to specific patients.

Craniofacial anomalies in a murine model of heterozygous fibroblast growth factor 10 gene mutation.

OBJECTIVE: Dysregulation of Fibroblast Growth Factor 10 (FGF10), a member of the family of Fibroblast Growth Factor (FGF) proteins, has been implicated in craniofacial and dental anomalies, including craniosynostosis, cleft palate, and Lacrimo-Auriculo-Dento-Digital Syndrome. The aim of this murine study was to assess the craniofacial and dental phenotypes associated with a heterozygous FGF10 gene (FGF10+/- ) mutation at skeletal maturity. METHODS: Skulls of 40 skeletally mature mice, comprising two genotypes (heterozygous FGF10+/- mutation, n = 22; wildtype, n = 18) and two sexes (male, n = 23; female, n = 17), were subjected to micro-computed tomography. Landmark-based linear dimensions were measured for the cranial vault, maxilla, mandible, and first molar teeth. Multivariate analysis of variance was performed to assess whether there were significant differences in the craniofacial and dental structures between genotypes and sexes. RESULTS: The craniomaxillary skeleton and the first molar teeth were smaller in the FGF10+/- mice (P < .05), but the mandible was unaffected. Sex did not have a significant effect on these structures (P > .05). Cranial sutural defects were noted in 5/22 (22.7%) mutant versus 2/18 (11.1%) wildtype mice, and cleft palate in only one (4.5%) mutant mouse. None of the mice displayed craniosynostosis, expansive bony lesions, bifid condyles, or impacted teeth. CONCLUSION: The FGF10+/- mutation was associated with craniomaxillary skeletal hypoplasia that probably arose from deficient (delayed) intramembranous ossification of the sutured bones. Overall, the skeletal and dental data suggest that the FGF10 gene plays an important role in the aetiology of craniofacial dysmorphology and malocclusion.

Barriers and co-designed strategies for the implementation of negative pressure wound therapy in acute pediatric burn care in Australia: A mixed method study.

PURPOSE: Pediatric burn injuries are a global clinical issue causing significant morbidity. Early adjunctive negative pressure wound therapy improves re-epithelialization rates in children with burns, yet adoption in acute burn care is inconsistent. This investigation aimed to determine barriers to the implementation of adjunctive negative pressure wound therapy for the acute management of pediatric burns and co-design targeted implementation strategies. METHODS: A sequential mixed methods design was used explore barriers to adjunctive negative pressure wound therapy implementation in acute pediatric burn care. An online questionnaire was disseminated to healthcare professionals within four major Australian pediatric hospitals, each with a dedicated burns service. Barriers were coded according to the Consolidated Framework for Implementation Research (CFIR). Semi-structured interviews with senior clinicians tailored implementation strategies to local contexts. A stakeholder consensus meeting consolidated implementation strategies and local processes. RESULTS: Sixty-three healthcare professionals participated in the questionnaire, and semi-structured interviews involved nine senior burn clinicians. We identified eight implementation barriers across all five CFIR domains then co-designed targeted strategies to address identified barriers. Barriers included lack of available resources, limited access to knowledge and information, individual stage of change, patient needs and resources, limited knowledge and beliefs about the intervention, lack of external policies, intervention complexity, and poor implementation planning. CONCLUSION: Multiple contextual factors affect negative pressure wound therapy uptake in acute pediatric burn settings. Results will inform a multi-state stepped-wedge cluster randomized controlled trial. Additional resources, education, training, updated policies, and guidelines are required for successful implementation. It is anticipated that adjunctive negative pressure wound therapy, in conjunction with tailored implementation strategies, will enhance adoption and sustainability.

Review of the requirements for effective mass casualty preparedness for trauma systems. A disaster waiting to happen?

Mass casualty incidents (MCIs) are diverse, unpredictable, and increasing in frequency, but preparation is possible and necessary. The nature of MCIs requires a trauma response but also requires effective and tested disaster preparedness planning. From an international perspective, the aims of this narrative review are to describe the key components necessary for optimisation of trauma system preparedness for MCIs, whether trauma systems and centres meet these components and areas for improvement of trauma system response. Many of the principles necessary for response to MCIs are embedded in trauma system design and trauma centre function. These include robust communication networks, established triage systems, and capacity to secure centres from threats to safety and quality of care. However, evidence from the current literature indicates the need to strengthen trauma system preparedness for MCIs through greater trauma leader representation at all levels of disaster preparedness planning, enhanced training of staff and simulated disaster training, expanded surge capacity planning, improved staff management and support during the MCI and in the post-disaster recovery phase, clear provision for the treatment of paediatric patients in disaster plans, and diversified and pre-agreed systems for essential supplies and services continuity. Mass casualty preparedness is a complex, iterative process that requires an integrated, multidisciplinary, and tiered approach. Through effective preparedness planning, trauma systems should be well-placed to deliver an optimal response when faced with MCIs.

Characteristics, management and changing incidence of children with empyema in a paediatric intensive care unit.

AIM: Paediatric intensive care unit (PICU) admissions for empyema increased following the 13-valent pneumococcal conjugate vaccine (PCV13). We describe the clinical characteristics, management and outcomes for children with empyema and compare incidence before and after PCV13. METHODS: Retrospective study of patients <18 years admitted to The Royal Children's Hospital Melbourne PICU with empyema between January 2016 and July 2019. We investigated the incidence of empyema during two time periods: 2007-2010 (pre-PCV13) and 2016-2019 (post-PCV13). RESULTS: Seventy-one children (1.9% of all PICU admissions) were admitted to PICU with empyema between 2016 and 2019. Sixty-one (86%) had unilateral disease, 11 (16%) presented with shock and 44 (62%) were ventilated. Streptococcus pneumoniae and group A Streptococcus were the most commonly identified pathogens. Forty-five (63%) were managed with video-assisted thoracoscopic surgery (VATS). There was a 31% reduction in empyema hospitalisations as a proportion of all hospitalisations (IRR 0.69, 95% CI 0.59-0.8), but a 2.8-fold increase in empyema PICU admissions as a proportion of all PICU admissions (95% CI 2.2-3.5, P < 0.001). For the PICU cohort, this was accompanied by reduction in PIM2 probability of death (median 1% vs. 1.9%, P = 0.02) and duration of intubation (median 69 h vs. 126.5 h, P = 0.045). CONCLUSIONS: In children with empyema in PICU 62% required ventilation, 16% had features of shock and 63% received VATS. Empyema admissions, as a proportion of all PICU admissions, increased in the era post-PCV13 compared to pre-PCV13 despite no increase in illness severity at admission.

Patient journey mapping to investigate quality and cultural safety in burn care for Aboriginal and Torres Strait Islander children and families - development, application and implications.

BACKGROUND: Quality and safety in Australian healthcare is inequitably distributed, highlighted by gaps in the provision of quality care for Aboriginal and Torres Strait Islander children. Burns have potential for long-term adverse outcomes, and quality care, including culturally safe care, is critical to recovery. This study aimed to develop and apply an Aboriginal Patient Journey Mapping (APJM) tool to investigate the quality of healthcare systems for burn care with Aboriginal and Torres Strait Islander children. STUDY DESIGN: Interface research methodology, using biomedical and cultural evidence, informed the modification of an existing APJM tool. The tool was then applied to the journey of one family accessing a paediatric tertiary burn care site. Data were collected through yarning with the family, case note review and clinician interviews. Data were analysed using Emden's core story and thematic analysis methods. Reflexivity informed consideration of the implications of the APJM tool, including its effectiveness and efficiency in eliciting information about quality and cultural safety. RESULTS: Through application of a modified APJM tool, gaps in quality care for Aboriginal and Torres Strait Islander children and families were identified at the individual, service and system levels. Engagement in innovative methodology incorporating more than biomedical standards of care, uncovered critical information about the experiences of culturally safe care in complex patient journeys. CONCLUSION: Based on our application of the tool, APJM can identify and evaluate specific aspects of culturally safe care as experienced by Aboriginal and Torres Strait Islander peoples and be used for quality improvement.

Preexisting neural factors that contribute to dysmotility in esophageal atresia: a systematic review.

Esophageal dysmotility in esophageal atresia (EA) relates to abnormal development of esophageal innervation and musculature and to the esophageal repair. Few studies have investigated the preexisting dysmotility in EA, present prior to surgery. This systematic review aims to summarize the literature on neuronal studies in EA, to understand the causative factors for esophageal dysmotility. We performed a systematic review (PubMed, EMBASE, EBM, CINAHL databases; January 1947-February 2021) in accordance with PRISMA (PROSPERO number CRD42020171014). Fourteen studies were identified (eleven human, 187 EA patients; three animal, 64 EA rat specimens). Neural factors affecting esophageal dysmotility in human and animal studies included proteins, enzymes, growth factors, and genes, which play a role in the nervous system or neuroendocrine system, some of which have functions as neuromodulators or neurotransmitters. This systematic review has identified neural factors that affect esophageal dysmotility and contributes toward our understanding of the underlying dysmotility in patients with EA. The studies identified are important and essential for successful translation of basic science knowledge to impact clinical practice and understanding. Level of evidence: III.

Quality of Life Outcomes in Primary Caregivers of Children with Esophageal Atresia.

OBJECTIVE: To investigate the quality of life (QoL) impact on primary caregivers of children with esophageal atresia. STUDY DESIGN: We used a prospective cohort study design, inviting primary caregivers of children with esophageal atresia to complete the following questionnaires: Parent Experience of Child Illness (PECI), Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, PROMIS Depression, 12-Item Short Form Survey (SF-12), and Pediatric Quality of Life Inventory (PedsQL). The PECI, PROMIS Anxiety and Depression, and SF-12 assessed caregiver QoL, and the PedsQL assessed patient QoL. Patients with Gross type E esophageal atresia served as controls. RESULTS: The primary caregivers of 100 patients (64 males, 36 females; median age, 4.6 years; range, 3.5 months to 19.0 years) completed questionnaires. The majority (76 of 100) of patients had Gross type C esophageal atresia. A VACTERL (vertebral anomalies, anorectal malformation, cardiac anomalies, tracheoesophageal fistula, renal anomalies, limb anomalies) association was found in 30, ≥1 esophageal dilatation was performed in 57, and fundoplication was performed in 11/100. When stratified by esophageal atresia types, significant differences were found in 2 PECI subscales (unresolved sorrow/anger, P = .02; uncertainty, P = .02), in PROMIS Anxiety (P = .02), and in SF-12 mental health (P = .02) and mental component summary scores (P = .02). No significant differences were found for VACTERL association, nor esophageal dilatation. Requirement for fundoplication resulted in lower SF-12 general health score, and lower PedsQL social and physical functioning scores. CONCLUSIONS: We have demonstrated that caring for a child with esophageal atresia and a previous requirement for fundoplication impacts caregiver QoL.

Periprocedural analgesia and sedation in air enema reduction for intussusception: A retrospective Australian cohort study.

AIM: Periprocedural analgesia or sedation for air enema reduction (AER) of intussusception is a matter of debate. We set out to review Australian periprocedural pain management in AER. METHODS: Retrospective electronic medical record review of emergency department presentations of intussusception at an Australian children's hospital over 2 years for periprocedural analgesia and sedation and short-term outcomes. RESULTS: A total of 73 patients (mean age 23 months) had ultrasound-confirmed intussusception. Prior to AER, analgesia was administered to 61 of 73 (83.5%) patients. Opioids were administered in 48 of 73 (65.8%) and 8 of 73 (11.0%) received sedation. Thirteen of 73 (17.8%, 95% confidence interval 9.0-26.6) had spontaneously reduced; 60/73 that underwent primary AER had successful reduction in 54 (90.0%, 95% confidence interval 82.4-97.6). A total of seven patients required surgery. No AER attempts were complicated by bowel perforation. CONCLUSION: The use of periprocedural analgesia for AER in this Australian series was common, whilst sedation use was infrequent. No perforations occurred.

Radiation burden in patients with esophageal atresia: a systematic review.

Esophageal atresia (EA) is the most common congenital esophageal disorder. Radiological imaging facilitates diagnosis, surgical interventions, and follow-up. Despite this, standardized monitoring guidelines are lacking. We aimed to: (1) review the literature regarding radiation burden in children with EA; (2) establish the presence of guidelines for diagnosis and follow-up in children with EA. The systematic review was performed according to PRISMA protocol. Two investigators conducted independent searches (PubMed, Ovid, Cochrane Review) and data extraction. Analysis focused on pre- and post-operative imaging type and frequency to determine the radiation burden. Seven studies met the inclusion criteria (337 patients). All authors agreed upon the need to minimize radiation burden, recommending symptoms-guided management, use of dosimeters, and non-radiating imaging. One study identified a median 130-fold increase in cumulative lifetime cancer risk in children with EA compared with other babies in the special care unit. The most common investigations were X-ray and CT (pre-operatively), and X-ray and contrast swallow (post-operatively). Standardized guidelines focused upon the frequency and type of radiological imaging for children with EA are lacking. Children with EA are subjected to more radiation exposure than the general population. Implementation of non-radiating imaging (ultrasonography, manometry) is recommended.

Selective approach to preoperative echocardiography in esophageal atresia.

PURPOSE: Preoperative echocardiography is used routinely in neonates with esophageal atresia to identify patients in whom congenital cardiac disease will impact upon anesthetic and surgical decision-making. We aimed to determine the suitability of selective preoperative echocardiography. METHODS: We performed a single-center retrospective review of neonates with esophageal atresia over 6 years (2010-2015) at our tertiary pediatric institution. Data included preoperative clinical examination, chest x-ray, and echocardiography. Endpoints were cardiovascular, respiratory, radiological, and echocardiography findings. Selective strategies were assessed using sensitivity, specificity, positive predictive value, and negative predictive value. RESULTS: We identified 115 neonates with esophageal atresia. All underwent preoperative echocardiography. Cardiac defects were identified in 49/115 (43%) (major 9/115, moderate 4/115). Sensitivity, specificity, positive predictive value, and negative predictive value of abnormal clinical and radiologic assessment for major and moderate cardiac defects were 92%, 25%, 13%, 96%; for clinical examination alone were 92%, 25%, 14%, 96%; for absence of murmur, cyanosis, and abnormal respiratory examination were 92%, 28%, 13%, 97%. Selective strategies reduce echocardiograms performed by 22%. CONCLUSION: Selective strategies allow for identification of neonates with esophageal atresia who may have deferral of echocardiogram unill after surgery. Selection may improve timeliness of care and resource utilization, without compromising patient safety.

Predictors of Mortality after Primary Discharge from Hospital in Patients with Esophageal Atresia.

OBJECTIVE: To describe esophageal atresia mortality rates and their associations in our cohort. STUDY DESIGN: Patients with esophageal atresia, managed at The Royal Children's Hospital, Melbourne (1980-2018), who subsequently died, were retrospectively identified from the prospective Nate Myers Oesophageal Atresia database. Data collected included patient and maternal demographics, vertebral anomalies, anorectal malformations, cardiovascular anomalies, tracheoesophageal fistula, renal anomalies, and limb defects (VACTERL) associations, mortality risk factors, and preoperative, operative, and postoperative findings. Mortality before discharge was defined as death during the initial admission. RESULTS: A total of 88 of the 650 patients (13.5%) died during the study period; mortality before discharge occurred in 66 of the 88 (75.0%); mortality after discharge occurred in 22 of the 88 (25.0%). Common causes of mortality before discharge were palliation for respiratory anomalies (15/66 [22.7%]), associated syndromes (11/66 [16.7%]), and neurologic anomalies (10/66 [15.2%]). The most common syndrome leading to palliation was trisomy 18 (7/66 [10.6%]). Causes of mortality after discharge had available documentation for 17 of 22 patients (77.3%). Common causes were respiratory compromise (6/17 [35.3%]), sudden unexplained deaths (6/17 [35.3%]), and Fanconi anemia (2/17 [11.8%]). Of the patients discharged from hospital, 22 of 584 (3.8%) subsequently died. There was no statistical difference in VACTERL association between mortality before discharge (31/61 [50.8%]) and mortality after discharge (11/20 [55.0%]), nor in incidence of twins between mortality before discharge (8/56 [14.3%]) and mortality after discharge (2/18 [11.1%]). CONCLUSIONS: We identified predictors of mortality in patients with esophageal atresia in a large prospective cohort. Parents of children with esophageal atresia must be counselled appropriately as to the likelihood of death after discharge from hospital.

Polyethylene Glycol Dosing for Constipation in Children Younger Than 24 Months: A Systematic Review.

OBJECTIVES: Evaluate safety and effectiveness of Polyethylene glycol (PEG) for chronic constipation in children aged younger than 24 months. Identify the optimum dose of PEG to manage chronic constipation in children aged younger than 24 months. METHODS: In this systematic review, Embase, Medline Ovid, Pubmed, and the Cochrane Library were searched between January 1, 2000 and February 1, 2019. Studies investigating functional constipation, in which patients younger than 24 months of age were treated with PEG, were considered as potentially eligible for review. Two authors screened the studies against inclusion/exclusion criteria. Study quality was assessed with the PEDro quality assessment, Cochrane risk of bias tool, and/or the Newcastle-Ottawa Scale. RESULTS: Five studies (2 randomized controlled trials, 3 retrospective chart reviews) satisfied selection criteria (n = 459). All studies employed different dosage categories: mean effective maintenance dose, mean initial dose, mean short-term and long-term dose, and mean daily dose. Dosage regimens were variable, with 0.45 to 1.1 g ·â€Škg ·â€Šday for PEG3350 and 0.48 to 0.65 g ·â€Škg ·â€Šday for PEG4000. Adverse effects were transient across all studies for all types of PEG; these included diarrhea and abdominal pain. CONCLUSIONS: This systematic review provided evidence for a lack of reported side effects from PEG for children aged younger than 24 months. Evidence to establish appropriate dosage regimens does not exist.An infographic accompanying this article can be found at http://links.lww.com/MPG/B839.

Traumatic spinal cord injury in Victoria, 2007-2016.

OBJECTIVE: To investigate trends in the incidence and causes of traumatic spinal cord injury (TSCI) in Victoria over a 10-year period. DESIGN, SETTING, PARTICIPANTS: Retrospective cohort study: analysis of Victorian State Trauma Registry (VSTR) data for people who sustained TSCIs during 2007-2016. MAIN OUTCOMES AND MEASURES: Temporal trends in population-based incidence rates of TSCI (injury to the spinal cord with an Abbreviated Injury Scale [AIS] score of 4 or more). RESULTS: There were 706 cases of TSCI, most the result of transport events (269 cases, 38%) or low falls (197 cases, 28%). The overall crude incidence of TSCI was 1.26 cases per 100 000 population (95% CI, 1.17-1.36 per 100 000 population), and did not change over the study period (incidence rate ratio [IRR], 1.01; 95% CI, 0.99-1.04). However, the incidence of TSCI resulting from low falls increased by 9% per year (95% CI, 4-15%). The proportion of TSCI cases classified as incomplete tetraplegia increased from 41% in 2007 to 55% in 2016 (P < 0.001). Overall in-hospital mortality was 15% (104 deaths), and was highest among people aged 65 years or more (31%, 70 deaths). CONCLUSIONS: Given the devastating consequences of TSCI, improved primary prevention strategies are needed, particularly as the incidence of TSCI did not decline over the study period. The epidemiologic profile of TSCI has shifted, with an increasing number of TSCI events in older adults. This change has implications for prevention, acute and post-discharge care, and support.

Presentation and outcomes in hypertrophic pyloric stenosis: An 11-year review.

AIM: To evaluate the trend in presentation and postoperative outcomes of infants with hypertrophic pyloric stenosis (HPS) over the last decade. METHODS: This was a multicentre retrospective study in two tertiary paediatric centres between 2005 and 2015 inclusive. Participants included 626 infants who underwent a pyloromyotomy for HPS. We collected data on presentation features (age, weight, clinical signs, blood gas results, ultrasound findings) and postoperative outcomes (length of stay (LOS), complications, time to first postoperative feed). RESULTS: No trend was identified during the study period with regards to age, weight, biochemical findings (pH, chloride, base excess) or pre-operative ultrasound measurements. There was a downtrend in the number of palpated tumours over time, with a mean of 36% of tumours clinically palpated. Pyloric wall thickness had a moderate association with LOS in patients admitted for >8 days (correlation = 0.4752) but had a weak negative association with shorter lengths of stay (≤8 day, correlation = -0.094). Overall, median time to first feed was 7.80 h and improved yearly during the study period (hazard ratio = 1.07). CONCLUSIONS: Patients presenting with HPS are not being identified at an earlier age or with fewer biochemical derangements, in contrast to our initial perceptions. Subsequently, biochemical derangements can still play an important role in the diagnosis of HPS, and attention needs to be given to fluid management and electrolyte correction in all patients with HPS.

Care coordination experiences of people with traumatic brain injury and their family members in the 4-years after injury: a qualitative analysis.

TITLE: Care coordination experiences of people with traumatic brain injury and their family members 4-years after injury: A qualitative analysis. AIM: To explore experiences of care coordination in the first 4-years after severe traumatic brain injury (TBI). METHODS: A qualitative study nested within a population-based longitudinal cohort study. Eighteen semi-structured telephone interviews were conducted 48-months post-injury with six adults living with severe TBI and the family members of 12 other adults living with severe TBI. Participants were identified through purposive sampling from the Victorian State Trauma Registry. A thematic analysis was undertaken. RESULTS: No person with TBI or their family member reported a case manager or care coordinator were involved in assisting with all aspects of their care. Many people with severe TBI experienced ineffective care coordination resulting in difficulty accessing services, variable quality in the timing, efficiency and appropriateness of services, an absence of regular progress evaluations and collaboratively formulated long-term plans. Some family members attempted to fill gaps in care, often without success. In contrast, effective care coordination was reported by one family member who advocated for services, closely monitored their relative, and effectively facilitated communication between services providers. CONCLUSION: Given the high cost, complexity and long-term nature of TBI recovery, more effective care coordination is required to consistently meet the needs of people with severe TBI.

Impact of Esophageal Atresia on the Success of Fundoplication for Gastroesophageal Reflux.

OBJECTIVES: Fundoplication is commonly performed in patients with a history of esophageal atresia (EA), however, the success of this surgery is reduced, as reflected by an increased rate of redo fundoplication. We aimed to determine whether EA impacts the prevalence of fundoplication, its timing, and performance of a redo operation. STUDY DESIGN: A single-center, retrospective review of all patients undergoing fundoplication over a 20-year period (1994-2013) was performed. Redo fundoplication was used as a surrogate for surgical failure. RESULTS: A total of 767 patients (patients with EA 85, those who did not have EA 682) underwent fundoplication during the study period. Median age (months) at primary fundoplication was lower in patients with EA (7.2 vs those who did not have EA 23.3; P < .001). Redo fundoplication rates between groups were not significantly different (EA 11/85 vs 53/682; P = .14). Median time (months) between primary and redo fundoplication was greater in patients with EA (36.2 vs 11.7; P = .03). CONCLUSIONS: Contrary to popular belief, the incidence of redo fundoplication was not significantly increased in patients with a history of EA. However, patients with EA underwent fundoplication at younger ages, which may be related to early life-threatening events in these patients. These results inform perioperative counseling, and highlight the importance of sustained surgical follow-up in patients with EA.

Piecemeal Deglutition and the Implications for Pressure Impedance Dysphagia Assessment in Pediatrics.

OBJECTIVES: High-resolution impedance manometry (HRIM) enables biomechanical swallow assessment. Piecemeal deglutition (PD) defines swallowing of a single bolus in 2 or more portions. We investigated PD sequences on HRIM recordings to ascertain appropriate swallow selection for analysis and to determine the impact of PD on swallow function measures. METHODS: Pharyngo-esophageal motility and bolus flow were assessed in 27 children (19 M, mean age 15 months) with repaired esophageal atresia and trachea-esophageal fistula, but who were asymptomatic of oropharyngeal dysphagia. A consistent volume of between 2 and 5 mL saline boluses was given to each patient. Retrospectively, PD sequences were defined based on the number of swallows required to clear the bolus from the oral cavity: pattern A = 1-2 swallows; pattern B = 3 swallows; and pattern C = 4+ swallows. The largest bolus volume swallowed was noted as the dominant swallow in each pattern. Pressure Flow Analysis defined contractility, distension and flow timing metrics. Data were averaged for each PD pattern, and compared with dominant swallows from each pattern. RESULTS: PD pattern B (43.7%) was the most prevalent across the cohort. PD patterns were similarly distributed across age groups (G1: <1 years, G2: 1-4 years). Differences in upper esophageal sphincter distension and pharyngeal flow timing measures were, however, seen in relation to both age and PD pattern, whereby a larger pharynx in older children elicited greater distension for a longer latency, and for larger volumes. CONCLUSIONS: PD reduces bolus volume, and biomechanical swallow measures are impacted. PD is a necessary consideration for accurate HRIM analysis of swallow function. Selection of dominant swallows from a PD sequence provides a swallow profile which best represents a child's swallow function, and should always be reported and interpreted in context of the PD sequence observed.

Patient-identified information and communication needs in the context of major trauma.

BACKGROUND: Navigating complex health care systems during the multiple phases of recovery following major trauma entails many challenges for injured patients. Patients' experiences communicating with health professionals are of particular importance in this context. The aim of this study was to explore seriously injured patients' perceptions of communication with and information provided by health professionals in their first 3-years following injury. METHODS: A qualitative study designed was used, nested within a population-based longitudinal cohort study. Semi-structured telephone interviews were undertaken with 65 major trauma patients, aged 17 years and older at the time of injury, identified through purposive sampling from the Victorian State Trauma Registry. A detailed thematic analysis was undertaken using a framework approach. RESULTS: Many seriously injured patients faced barriers to communication with health professionals in the hospital, rehabilitation and in the community settings. Key themes related to limited contact with health professionals, insufficient information provision, and challenges with information coordination. Communication difficulties were particularly apparent when many health professionals were involved in patient care, or when patients transitioned from hospital to rehabilitation or to the community. Difficulties in patient-health professional engagement compromised communication and exchange of information particularly at transitions of care, e.g., discharge from hospital. Conversely, positive attributes displayed by health professionals such as active discussion, clear language, listening and an empathetic manner, all facilitated effective communication. Most patients preferred communication consistent with patient-centred approaches, and the use of multiple modes to communicate information. CONCLUSIONS: The communication and information needs of seriously injured patients were inconsistently met over the course of their recovery continuum. To assist patients along their recovery trajectories, patient-centred communication approaches and considerations for environmental and patients' health literacy are recommended. Additionally, assistance with information coordination and comprehensive multimodal information provision should be available for injured patients.

Oesophageal atresia: Are "long gap" patients at greater anesthetic risk?

BACKGROUND: Long gap oesophageal atresia occurs in approximately 10% of all oesophageal atresia infants and surgical repair is often difficult with significant postoperative complications. Our aim was to describe the perioperative course, morbidity, and early results following repair of long gap oesophageal atresia and to identify factors which may be associated with complications. METHODS: This is a single center retrospective cohort study of consecutive patients with oesophageal atresia undergoing surgical repair at The Royal Children's Hospital Melbourne from January 2006 to June 2017. RESULTS: Two hundred and thirty-nine consecutive oesophageal atresia infants included 44 long gap oesophageal atresia infants and 195 non-long gap infants. A high rate of prematurity (24.7%), major cardiac (17%), and other surgically relevant malformations (12.6%) was found in both groups. The median age at oesophageal anastomosis surgery was 65.5 days for the long gap group vs 1 day for the oesophageal atresia group (mean difference 56.8 days, 95% CI 48.1-65.5 days, P < .01). Surgery for long gap oesophageal atresia included immediate primary anastomosis (n = 10), delayed primary anastomosis (n = 11), oesophageal lengthening techniques (n = 12) and primary oesophageal replacement (n = 6). Long gap oesophageal atresia was not associated with an increased incidence of difficult intubation (OR 2.8, 95% CI 0.6-22.1, P = .17), intraoperative hypoxemia (OR 1.6, 95% CI 0.6-4.5, P = .32), or hypotension (OR 0.9, 95% CI 0.5-1.8, P = .81). The surgical duration (177.7 vs 202.1 minute, mean difference [95% CI], 28 [5.5-50.4 minutes], P = .04) and mean duration of postoperative mechanical ventilation (107 vs 199.8 hours, mean difference [95% CI], 91.8 [34.5-149.1 hours], P < .01) were shorter for the non-long gap group. Overall in-hospital mortality was 7.5% (15.9% long gap vs 5.6% non-long gap oesophageal atresia OR 1.1, 95% CI 0.4-3.4, P = .85). CONCLUSION: Long gap oesophageal atresia infants have a similar incidence of perioperative complications to other infants with oesophageal atresia. Current surgical approaches to long gap repair, however, are associated with longer anesthetic exposures and require multiple procedures in infancy to achieve oesophageal continuity.
