ABSTRACT

The coronavirus 19 (COVID-19) pandemic has affected hundreds of millions of people worldwide: in most of cases children and young people developed asymptomatic or pauci-symptomatic clinical pictures. However authors have showed that there are some categories of childhood more vulnerable to COVID-19 infection such as newborns or children with comorbidities. We report for the first time to the best of our knowledge about microvascular dysfunction in three pediatric clinical cases who developed COVID-19 infections with need of pediatric critical care. We found that sublingual microcirculation is altered in children with severe COVID-19 infection. Our findings confirmed most of data already observed by other authors in adult population affected by severe COVID-19 infection, but with distinct characteristics than microcirculation alterations previous observed in a clinical case of MIS-C. However we cannot establish direct correlation between microcirculation analysis and clinical or laboratory parameters in our series, by our experience we have found that sublingual microcirculation analysis allow clinicians to report directly about microcirculation dysfunction in COVID-19 patients and it could be a valuable bedside technique to monitor thrombosis complication in this population.

ABSTRACT

INTRODUCTION: Acute pediatric poisoning is an emerging health and social problem. The aim of this study is to describe the characteristics of a large pediatric cohort exposed to xenobiotics, through the analysis of a Pediatric Poison Control Center (PPCc) registry. METHODS: This study, conducted in the Pediatric Hospital Bambino Gesù of Rome, a reference National Pediatric Hospital, collected data of children whose parents or caregivers contacted the PPCc by phone (group "P"), or who presented to the Emergency Department (group "ED"), during the three-year period 2014-2016. Data were prospectively and systematically collected in a pre-set electronic registry. Comparisons among age groups were performed and multivariable logistic regression models used to investigate associations with outcomes (hospital referral for "P", and hospital admission for "ED"group). RESULTS: We collected data of 1611 children on group P and 1075 on group ED. Both groups were exposed to both pharmaceutical and non-pharmaceutical agents. Pharmaceutical agent exposure increased with age and the most common route of exposure was oral. Only 10% among P group were symptomatic children, with gastrointestinal symptoms. Among the ED patients, 30% were symptomatic children mostly with gastrointestinal (55.4%) and neurologic symptoms (23.8%). Intentional exposure (abuse substance and suicide attempt), which involved 7.7% of patients, was associated with older age and Hospital admission. CONCLUSIONS: Our study describes the characteristics of xenobiotics exposures in different paediatric age groups, highlighting the impact of both pharmacological and intentional exposure. Furthermore, our study shows the utility of a specific PPCc, either through Phone support or by direct access to ED. PPCc phone counselling could avoid unnecessary access to the ED, a relevant achievement, particularly in the time of a pandemic.

ABSTRACT

In Italy viper bites represent an uncommon event, though envenomation can cause severe complications, more in children than adults, because of dose/body size ratio. We present a case series within a selected population: 10 Italian cases (from Rome surroundings) of viperbites requiring PICU admission, over a 5-year interval. Five children showed a systemic involvement, whereas the remaining patients showed a damage. All were managed and closely monitored in an ICU setting. Relevant clinical findings and therapeutic approach, ICU course and complications have been recorded. Age range was 3-15 years with mean age of 6,9 (SD±4,58) years; 2 patients needed respiratory support beyond oxygen supplementation. Most patients underwent fluid loading, while hemodynamic support was given to4/10. Median PICU stay was 60 hours (IQR=24.0-75.5). No mortality was reported. Indications and precautions for administration of antivenom in the last years have been reviewed: early treatment seems to reduce mortality/morbidity, though representing a threat for children. Current recommendations for the treatment of viper envenomation have been described, based on a literature's review and the application of these knowledges to clinical reality of our PICUs. Therefore, paediatric patients with systemic or rapidly evolving symptoms should be monitored carefully for the development of bite-related complications in an ICU setting mostly in younger children.

ABSTRACT

Effective and adequate therapy to control pain and stress are essential in managing children in Pediatric Intensive Care Unit (PICU) undergoing painful invasive procedures, this should be, but is not yet, one of our main aims. Aware that this difficult mission must be pursued in a systematic, multimodal and multitasking way, the Studying Group on Analgosedation in PICU from the Italian Society of Neonatal and Paediatric Anesthesia and Intensive Care (SARNePI) is providing its recommendations.

ABSTRACT

BACKGROUND: Currently there is no clear evidence of how changes in hemodynamic parameters are involved in the onset of neurogenic pulmonary edema. Aim of the study has been to correlate the principal variations of the intracranial pressure and volumetric hemodynamic parameters with the variations of extravascular lung water following severe head trauma in children. METHODS: We studied 28 children, 16 males and 12 females, mean ± SD age 71±29 months (range 24-130 months), admitted for traumatic head injury with Glasgow Coma scale ≤8. All patients received volumetric hemodynamic, and intracranial pressure monitoring following initial resuscitation and every four hours thereafter or whenever a hemodynamic deterioration was suspected. All readings were divided in 2 groups: with intracranial pressure (ICP) >15 mmHg or ≤15 mmHg. RESULTS: During the cumulative in hospital stay a total 508 sets of measurements were done. In the group with ICP >15 mmHg vs. that with ICP ≤15 mmHg we observed increased Extravascular Lung Water Index (EVLWi) (11.05±2.28 vs. 6.96±0.87 P<0.0001) and pulmonary permeability (8.50±1.19 vs. 5.08±0.90, P<0.0001), and decreased systemic vascular resistances, (1,451±371 vs. 1,602±447 P<0.0001) cerebral perfusion (48.87±18.67 vs. 69.72±11.36 P<0.0001) and PaO2/FiO2 ratio (349±122 vs. 490±96 P<0.0001). There was a significant correlation between EVLWi and pulmonary permeability (R2=0.83, P<0.0001). Fluid overload and cardiac functional index did not change significantly. CONCLUSION: The increased EVLWi observed in children following severe head trauma seems mainly related with pulmonary vascular permeability which is significantly increased when ICP is >15 mmHg.

ABSTRACT

Although significant steps have been taken to monitor complex hemodynamics in neonatal and pediatric intensive care units, cardiovascular function in neonates is still evaluated by measuring blood pressure, heart rate, diuresis, central venous pressure (if a central venous catheter was placed), capillary refill time and oxygen saturation measurement in the upper and lower extremities. The use of other non-invasive or invasive technologies (for example, continuous impedance cardiography, transesophageal Doppler and continuous pulse contour methods) is, in fact, quite problematic in neonates in whom relevant hemodynamic changes are common during the transition to postnatal life. For these reasons, use of transthoracic echocardiography, performed by skilled pediatric intensivists, is increasing in several dedicated centers to guide treatment choices in hemodynamically unstable neonates.

ABSTRACT

Diabetic ketoacidosis is a severe complication of type I diabetes. A 13-year-old female (40 kg) patient was admitted to our Intensive Care Unit with severe metabolic acidosis (pH: 6.8), hyperglycemia (835 mg/dL) and coma. Her hemodynamic conditions were unstable and, even though a large amount of plasma expanders, crystalloids, and inotropic support were supplied, the patient went into cardiac arrest in the first hour of treatment. After resuscitation, a better hemodynamic balance was achieved and metabolic acidosis was treated with fluid replacement therapy, continuous insulin infusion, and Tris-hydroxymethyl aminomethane (THAM) as a buffering agent. This therapy rapidly improved her metabolic conditions. The patient was discharged 5 days after Intensive Care Unit admission in good condition and without neurological sequelae.

ABSTRACT

BACKGROUND: As far as paediatric traumatic brain injury is concerned, it is difficult to quantify the extent of the primary insult, to monitor secondary changes and to predict neurological outcomes by means of the currently used diagnostic tools: physical examination, Glasgow Coma Scale (GCS) score and computed tomography. For this reason, several papers focused on the use of biochemical markers (S100B, neuron-specific enolase) to detect and define the severity of brain damage and predict outcome after traumatic head injury or cardiac arrest. OBJECTIVE: The aim of this paper is measuring the range of S100B serum concentrations in children affected by traumatic brain injury and describing the possible roles of this protein in the reaction to trauma. METHODS: Fifteen children aged 1-15 years were included in the study. Traumatic brain injury severity was defined by paediatric GCS score as mild (9 patients), moderate (2 patients) or severe (4 patients). Blood samples for S100B serum measurement were taken at emergency department admission and after 48 h. RESULTS: The serum S100B concentration was higher in the group of severe trauma patients, who scored the lowest on the GCS at admission, and among them, the highest values were reported by the children with concomitant peripheral lesions. CONCLUSIONS: The role of S100B in paediatric traumatic brain injury has not been clarified yet, and the interpretation of its increase when the head trauma is associated with other injuries needs the understanding of the physiopathological mechanisms that rule its release in the systemic circulation. The levels of S100B in serum after a brain injury could be related to the mechanical discharge from a destroyed blood-brain barrier, or they could be due to the active expression by the brain, as a part of its involvement in the systemic inflammatory reaction. Early increase of this protein is not a reliable prognostic index of neurological outcome after pediatric traumatic brain injury, since even very elevated values are compatible with a complete neurological recovery.

ABSTRACT

La finalidad de nuestro estudio ha sido la de evaluar la existencia de posibles correlaciones entre los principales indicadores volumétricos de carga previa y de función cardiaca, obtenida mediante el sistema PiCCO® (Pulsion Medical Systems, Munich, Alemania), con todos los datos derivados del análisis sistemático de la radiografía de tórax en proyección antero posterior, así como el pedúnculo vascular (VPW) y el índice cardiotorácico (RCT). Materiales y Métodos: Hemos incluido 15 pacientes y analizado conjuntamente 79 radiografías de pacientes electivos. Todos fueron sometidos a monitorización hemodinámica mediante PiCCO y al estudio de los parámetros radiográficos obtenidos (VPW, RCT). El análisis: cálculo de la media y desviación estándar; un análisis de la correlación para las siguientes parejas de parámetros: volumen de sangre intratorácica (ITBVI)-RCT, ITBVI-VPW, agua extravascular (EVLWI )-RCT, EVLWI-VPW . Resultados. Las parejas de los valores estudiados han evidenciado una correlación linear con R igual a 0.54 entre EVLWI-RCT. Discusión. Aunque es un estudio preliminar, los hallazgos más significativos se ven en las variaciones de RCT, que presentan una correspondencia con el edema intersticial antes de que aparezca un incremento crítico de la rata de líquido alveolar. En nuestra experiencia no hemos evidenciado una fuerte correlación entre VPW y los normales indicadores volumétricos de precarga. De acuerdo con los datos en literatura y también en la experiencia pediátrica, estos instrumentos presentan límites que aún no consienten sustituir completamente a la correcta cuantificación de la rata de agua extravascular, en respuesta al incremento volémico.

ABSTRACT

AIM: The aim of this study was to evaluate the analgesic effects of remifentanyl on mechanically ventilated newborns. METHODS: Eighteen newborns, mechanically ventilated, were submitted to continuous infusion of R. A pain scale was used to evaluate comfort during mechanical ventilation. Data were collected at T0, T1, Tn, T ext, T post-ext; statistical analysis was performed by Student's t test and Pearson coefficient. RESULTS: Mean R infusion time was 66.94+/-22.24 h, with mean dose of R 0.146+/-0.038 gamma/kg/min. Mean time to reach comfort was 20+/-13.11 h with a mean infusion of R equal to 0.173+/-0.146 gamma/kg/min; R was 0.18+/-0.039 gamma/kg/min on pressure controlled ventilation and R was 0.09+/- 0.045 gamma/kg/min on assisted ventilation. Statistically significant was considered the decrease in HR as well as the increase of SpO2 at T0 vs 30 min after infusion. CONCLUSION: No adverse effects were observed during and after infusion.

ABSTRACT

AIM: Hemodynamic monitoring is an important step in the management of critically ill children despite the difficulty in measuring preload indices continuously. The aim of the study was to analyze cardiac output parameters and preload indices after acute changes in mean airway pressure and volemia. METHODS: Twenty-three children treated at our unit were enrolled in a prospective non randomized cohort study. Respiration was supported by controlled mechanical ventilation with positive expiratory-end pressure (PEEP), peak inspiratory pressure <20 cm H(2)O and mean airway pressure <10 cm H(2)O, and hemodynamic monitoring using the PiCCO system. Hemodynamic parameters were measured at T0 (base line), T(1) (after an increase in PEEP of 5 cm H(2)O for 10 min), and T(2) (after fluid challenge). The statistical analysis (BMPD New System software package) comprised comparison of changes at T(0) vs T(1), T(1) vs T(2) and T(0) vs T(2), construction of 3 correlation matrices and multiple linear regression analysis. RESULTS: Sixty-nine hemodynamic parameters were measured in the 23 patients. A comparison between T(0) and T(1) showed no significant changes; differences between T(0) and T(2) were found for cardiac index (CI), (p=0.003); between T(0) and T(2) significant differences were found for CI (p=0.0015), intrathoracic blood volume index (ITBVI) (p=0.04) and stroke volume index (SVI) (p=0.06). The analysis of the correlation matrices yielded ITBVI with CI (p=0.0006), ITBVI with SVI (p=1 x 10(-5)), CI with SVI (p=0.002); a significant correlation between CI and extravascular lung water index (EVLWI) was found only at T(1). Multiple linear regression analysis showed that ITBVI and SVI were predictive for variance of CI at each time point. CONCLUSION: ITBVI measured by a volumetric monitoring system such as the PiCCO may be considered a sensitive preload indicator also in critically ill children.

ABSTRACT

BACKGROUND: Uremic patients on regular dialysis treatment (RDT) obtain and maintain with difficulty an adequate nutritional status. Successful kidney transplantation allows remarkable rehabilitation of patients with end-stage renal disease previously on RDT. However, information concerning the role of dietary protein restriction in the treatment of patients with chronic transplant rejection is scarce. PATIENTS AND METHODS: The role of dietary protein restriction in the treatment of patients with chronic transplant rejection was studied over 10 years in 42 patients with a kidney transplant to examine longterm renal and nutritional responses to dietary protein on graft renal function. In these patients, renal function was checked monthly, clinical evaluation and anthropometric measurements studied, nutritional status and all patients' diets were recorded. RESULTS: In 18 of these patients, biochemical signs of renal failure were found. A diet with 35 Kcal/kg and 0.7 - 0.8 grams of protein/Kg was instituted. Renal function studied every six months for 10 years showed improvement or stabilization. The low protein diet was associated with a significant reduction in 24-hour urinary protein excretion, without any change in blood pressure. Protein restriction was not associated with changes in serum protein. CONCLUSIONS: Our long-term study suggests that moderate protein intake may improve the course of chronic rejection and that restriction in protein intake may be a useful strategy in slowing the progression of renal disease in chronic rejection.

ABSTRACT

Preemptive analgesia is based on administration of an analgesic before a painful stimulus generates, so as to prevent the subsequent rebound mechanism. Tissue injury results in disruption of the processing mechanisms of noxious stimuli afferent to the CNS (central nervous system) by way of an increase of inputs in the spinal cord. These reactions may be reduced by the administration of opioids. Few studies on preemptive analgesia with opioids in children are available, and none of them is concerned with pediatric neurosurgery. Tramadol and fentanyl are synthetic opioids which are relatively new and act through the activation of pain-inhibitory mechanisms. We conducted a randomized, prospective trial on the preemptive effects in children of these two analgesic drugs, administered according to three different protocols: tramadol as a bolus (1 mg/kg); tramadol by continuous infusion (150 microg/kg per h); fentanyl by continuous infusion (2 microg/kg per h). In all, 42 children undergoing major neurosurgical operations were enrolled in the study, 14 in each treatment group. Each treatment was started at the induction of general anesthesia and continued throughout the entire duration of the operation. The postoperative pain evaluation was conducted in the Pediatric Intensive Care Unit at the end of the surgical operations and involved comparison of any changes in behavioral (AFS scale and CHEOPS score) and hemodynamic (heart rate, respiratory rate, systolic and diastolic arterial pressure, oxygen saturation, O(2) and CO(2) partial pressure) parameters. Only 2 children, both in group A, needed further drug administration postoperatively. No significant side effects were noticed in any of the three groups, except that in group A there was a higher incidence of nausea and vomiting. Tramadol efficacy seems to be better when it is administered in continuous infusion; this treatment modality also leads to fewer adverse effects. Fentanyl, in contrast, proved to be superior to tramadol in the treatment of postoperative pain. In conclusion, preemptive analgesia is a valid technique for the treatment of acute pain in children undergoing major neurosurgical operations.

ABSTRACT

The authors describe the results obtained in 13 consecutive cases of craniosynostosis operated on according to a protocol devised at avoiding allogeneic blood transfusion. The protocol is based on pre- and postoperative treatment with erythropoietin, preoperative autologous blood donation, preoperative normovolemic hemodilution and intraoperative blood salvage. Nine subjects were affected by simple forms of craniosynostosis, whereas the remaining 4 presented with oxycephaly or craniofacial syndromes. Five of the 13 children were under 7 months and a further 3, under 10 months of age at the time of the surgical operation. Seven children weighed less than 10 kg. Allogeneic blood transfusion was avoided in 11 of the 13 children considered. Two failures - defined as the necessity to reinfuse the patient with an allogeneic blood transfusion - were recorded, 1 of them resulting from an unexpected hemorrhage during surgery. The results obtained indicate that this protocol designed to avoid allogeneic blood transfusion can be safely applied in the great majority of children with craniosynostosis, even when the surgical correction is carried out early in life.
