Postoperative Urinary Retention after Pediatric Orthopedic Surgery.

Purpose: This study aims to describe the incidence of postoperative urinary retention among pediatric patients undergoing orthopedic surgery and identify risk factors. Methods: The Pediatric Health Information System was used to identify children aged 1−18 years who underwent orthopedic surgery. Collected from each patient's record were demographic information, principal procedure during hospitalization, the presence of neurologic/neuromuscular conditions and other complex chronic medical conditions, the total postoperative length of stay, and the presence of postoperative urinary retention. Results: The overall incidence of postoperative urinary retention was 0.38%. Children with complex chronic neuromuscular conditions (OR 11.54 (95% CI 9.60−13.88), p = < 0.001) and complex chronic non-neuromuscular medical conditions (OR 5.07 (95% CI 4.11−6.25), p ≤ 0.001) had a substantially increased incidence of urinary retention. Surgeries on the spine (OR 3.98 (95% CI 3.28−4.82, p ≤ 0.001) and femur/hip (OR 3.63 (95% CI 3.03−4.36), p ≤ 0.001) were also associated with an increased incidence. Conclusions: Children with complex chronic neuromuscular conditions have a substantially increased risk of experiencing postoperative urinary retention. Complex chronic non-neuromuscular medical conditions and surgeries to the spine, hip, and femur also carry a notably increased risk.

Perceived Physician Empathy in Pediatric Orthopedics: A Cross-Sectional Study.

Empathy is the cornerstone of the patient-physician relationship and is consistently ranked by patients as one of the most important factors in the quality of their care. In this paper we examine the degree to which perceived physician empathy is associated with the characteristics of the caregiver (parent or legal guardian) and physician in pediatric orthopedic surgery. This was a cross-sectional survey study of 200 English-speaking caregivers of pediatric patients at a large children's hospital. The Consultation and Relational Empathy (CARE) Measure was used to measure perceived physician empathy. Only if the caregiver felt carefully listened to by the physician (p-value < 0.001), and if the physician showed respect for what the caregiver had to say (p-value = 0.007) were statistically significant and positively associated with perceived physician empathy. The most significant determinant of perceived physician empathy is whether the caregiver felt listened to during the encounter. Other factors such as caregiver demographics, health literacy, self-rated mental health, wait time, and time spent with the physician do not significantly affect perceived physician empathy.

Quantitative Electroencephalography After Pediatric Anterior Circulation Stroke.

OBJECTIVE: Regional differences were investigated in quantitative EEG (QEEG) characteristics and associations of QEEG to hemodynamics after pediatric acute stroke. METHODS: Quantitative EEG was analyzed, including power in delta, theta, alpha, and beta bands, alpha-delta power ratio, total power, and spectral edge frequency from 11 children with unilateral, anterior circulation strokes during the first 24 hours of continuous EEG recording. Differences between injured and uninjured hemispheres were assessed using multivariate dynamic structural equations modeling. Dynamic structural equations modeling was applied to six children with hemorrhagic stroke undergoing arterial blood pressure, heart rate, and cerebral oximetry monitoring to investigate associations between hemodynamics with QEEG adjacent to anterior circulation regions. RESULTS: All patients with acute ischemic stroke ( n = 5) had lower alpha and beta power and spectral edge frequency on injured compared with uninjured regions. This was not consistent after hemorrhagic stroke ( n = 6). All hemorrhagic stroke patients demonstrated negative association of total power with arterial blood pressure within injured regions. No consistency was observed for direction or strength of association in other QEEG measures to arterial blood pressure nor were such consistent relationships observed for any QEEG measure studied in relation to heart rate or cerebral oximetry. CONCLUSIONS: After pediatric anterior circulation acute ischemic stroke, reduced spectral edge frequency and alpha and beta power can be observed on injured as compared with noninjured regions. After pediatric anterior circulation hemorrhagic stroke, total power can be negatively associated with arterial blood pressure within injured regions. Larger studies are needed to understand conditions in which QEEG patterns manifest and relate to hemodynamics and brain penumbra.

Sphenopalatine Ganglion Nerve Block for the Treatment of Migraine Headaches in the Pediatric Population.

BACKGROUND: Persistent headaches and migraines are common in pediatrics with various treatment options. The sphenopalatine ganglion (SPG) has been identified as communicating with the parasympathetic autonomic nervous system and pain receptors. In adults, SPG block is an established treatment but there is no published literature in pediatrics. OBJECTIVES: The purpose of this study is to analyze the SPG block in pediatrics. STUDY DESIGN: Retrospective, single-center study. SETTING: This study was conducted at Phoenix Children's Hospital in Phoenix, Arizona. METHODS: A comprehensive review of patient charts from 2015-2018 of all pediatric SPG blockades performed by interventional radiology were included in the analysis. Utilizing fluoroscopic guidance, a SphenoCath was inserted into each nostril and after confirming position, and 4% lidocaine injected. Pre- and postprocedural pain was assessed using the Visual Analog Scale (VAS). Immediate and acute complications were documented. RESULTS: A total of 489 SPG blocks were performed in patients between ages 6 and 26 years who were diagnosed with migraine or status migrainosus. One hundred percent technical success was achieved with mean reduction of pain scores of 2.4, which was statistically significant (P < 0.0001). There were no immediate or acute complications. LIMITATIONS: Results of this study were based on retrospective study. The use of VAS may be subjective, and the need of a prospective study may be necessary. CONCLUSIONS: With 100% technical success, statistically significant pain reduction, and no complications, we support SPG block in the pediatric population as a simple, efficacious, and safe treatment option for refractory headaches. It is routinely performed in less than 10 minutes and commonly negates the need for inpatient headache pain management. Given its minimal invasivity, we support the use of SPG blockade as a therapeutic treatment in refractory pediatric migraines as it reduces the need for intravenous medications, prolonged pain control, or hospital admission.

Determinants of caregiver satisfaction in pediatric orthopedics.

This study investigates determinants of pediatric orthopedic surgery patients' parent or guardian (caregiver) satisfaction with the physician in an outpatient office setting. This was a cross-sectional survey study of 200 English-speaking caregivers of pediatric patients that checked into the pediatric orthopedic clinic at the authors' institution from 1 March 2017 to 1 November 2018. Questionnaires given in clinic include the Newest Vital Sign and The Literacy in Musculoskeletal Problems survey to measure general and musculoskeletal health literacy, respectively, demographic information, expected/estimated wait time, Consultation and Relational Empathy Measure, and Consumer Assessment of Healthcare Providers and Systems Clinician and Group. After multivariate regression, only perceived physician empathy as measured by the Consultation and Relational Empathy Measure score was significantly correlated with caregiver satisfaction (P < 0.0001), accounting for 56% of the variability of caregiver satisfaction scores. The odds of a satisfaction score of at least 9 out of 10 were 21% higher for every unit increase of the Consultation and Relational Empathy Measure score [odds ratio = 1.21 (P < 0.0001)]. After logistic regression, the caregiver's gender was also correlated with patient satisfaction and the odds of a patient satisfaction score ≥9 for males was less than 1/4th that of females [odds ratio = 0.16 (P = 0.040)]. The most important determinant of caregiver satisfaction with the physician in an outpatient pediatric orthopedic setting is perceived physician empathy. This accounts for the majority of the caregiver's satisfaction. This is the first study to determine this relationship in pediatric orthopedic surgery.

Prediction model for cardiac allograft vasculopathy: Comparison of three multivariable methods.

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains an important cause of graft failure after heart transplantation (HT). Although many risk factors for CAV have been identified, there are no clinical prediction models that enable clinicians to determine each recipient's risk of CAV. METHODS: We studied a cohort of 14 328 heart transplant recipients whose data were reported to the International Society for Heart and Lung Transplantation Registry between 2000 and 2010. The cohort was divided into training (75%) and test (25%) sets. Multivariable modeling was performed in the test set using variables available at the time of heart transplant using three methods: (i) stepwise Cox proportional hazard, (ii) regularized Cox proportional hazard, and (iii) Bayesian network. RESULTS: Cardiac allograft vasculopathy developed in 4259 recipients (29.7%) at a median time of 3.0 years after HT. The regularized Cox proportional hazard model yielded the optimal performance and was also the most parsimonious. We deployed this model as an Internet-based risk calculator application. CONCLUSIONS: We have developed a clinical prediction model for assessing a recipient's risk of CAV using variables available at the time of HT. Application of this model may allow clinicians to determine which recipients will benefit from interventions to reduce the risk of development and progression of CAV.

Does valvuloarterial impedance impact prognosis after surgery for severe aortic stenosis in the elderly?

BACKGROUND: Valvuloarterial impedance (Zva) was introduced as a prognostic measure in patients with aortic stenosis (AS). However, it is unclear whether Zva has a prognostic impact on survival after surgical aortic valve replacement (AVR) in patients with severe AS with preserved ejection fraction (EF). METHODS: We retrospectively reviewed 929 consecutive patients who had AVR. We investigated 170 elderly patients (age >65 years, mean 76 years) who had AVR secondary to severe AS (mean gradient ≥40 mm Hg; aortic valve area ≤1 cm(2); peak velocity ≥4 m/s). Patients with EF <50%, greater than moderate aortic regurgitation, prior heart surgery and concomitant mitral or tricuspid valve surgery were excluded. Zva was calculated and the patients were divided into two groups; low Zva, Zva <4.3 (n=82) and high Zva, Zva ≥4.3 (n=88). The end point was all-cause of death. Survival curves were calculated according to Kaplan-Meier method. RESULTS: Age, prevalence of hypertension, diabetes, chronic kidney disease (CKD), atrial fibrillation, symptoms, EF, E/e' and concomitant coronary artery bypass graft were not different between the groups. Survival was not different between the groups at 5 years (70% in low Zva and 81% in high Zva; p=0.21) and for the entire follow-up period (p=0.23). Only age was a significant factor in predicting survival by multivariate analyses in Cox proportional hazards model after adjusting for Zva, CKD, atrial fibrillation and hypertension. CONCLUSIONS: Our results suggest that preoperative Zva does not have a prognostic impact on postoperative survival in elderly patients with severe AS with preserved EF. Further investigation is needed to elucidate the controversial results.
