- Practices of use of nasal intermittent positive pressure ventilation (NIPPV) in neonatology in northeastern Brazil(2012) MEDEIROS, Sara Karla F. de; CARVALHO, Werther Brunow de; SORIANO, Claudio F. R.Objective: To investigate the use of nasal intermittent positive pressure ventilation (NIPPV) in level three neonatal intensive care units (NICU) in northeastern Brazil. Methods: This observational cross-sectional survey was conducted from March 2009 to January 2010 in all level three NICUs in northeastern Brazil that are registered in the Brazilian Registry of Health Establishments (Cadastro Nacional de Estabelecimentos de Saude, CNES) of the Ministry of Health. Questionnaires about the use of NIPPV were sent to the NICU directors in each institution. Statistical analysis was conducted using the software Epi-Info 6.04 and double data entry. A chi-square test was used to compare variables, and the level of statistical significance was set at p <= 0.05. Results: This study identified 93 level three NICUs in northeastern Brazil registered in CNES, and 87% answered the study questionnaire. Most classified themselves as private institutions (30.7%); 98.7% used NIPPV; 92.8 % adapted mechanical ventilators for NIPPV and used short binasal prongs as the interface (94.2%). Only 17.3% of the units had a protocol for the use of NIPPV. Mean positive inspiratory pressure and positive end-expiratory pressure were 20.0 cmH(2)O (standard deviation [SD]: 4.47) and 5.0 cmH(2)O (SD: 0.84). Conclusion: NICUs in northeastern Brazil use nasal intermittent positive pressure ventilation, but indications and ventilation settings are not the same in the different institutions.
- Nebulized 0.5, 2.5 and 5 ml L-epinephrine for post-extubation stridor in children: a prospective, randomized, double-blind clinical trial(2012) SILVA, Paulo Sergio Lucas da; FONSECA, Marcelo Cunio Machado; IGLESIAS, Simone Brasil Oliveira; LOPES JUNIOR, Emilio; AGUIAR, Vania Euzebio de; CARVALHO, Werther Brunow deNebulized l-epinephrine has been recommended for the treatment of viral croup. However, the few studies assessing its effect on post-extubation stridor (PES) have shown conflicting results. We compared the efficacy and safety of nebulized l-epinephrine at three different doses for the treatment of PES. We conducted a prospective, randomized, double-blind trial including all consecutive children with a PES score of a parts per thousand yen4 (Westley score). The primary efficacy outcome was change in PES score at 40 min. A reduction of a parts per thousand yen2 points in stridor score was defined as clinically significant. A total of 96 patients were randomly assigned to receive one of three doses of nebulized l-epinephrine upon achieving a PES score of 4 or more following extubation. Stridor score and vital signs were recorded before treatment, and at 20, 40, 60 and 180 min after nebulization. Baseline characteristics were similar among all study groups. No significant difference was detected among the treatments based on change in Westley score by intent-to-treat analysis. In addition, the difference in the number of patients who clinically improved among the treatment groups was not significant (p = 0.54). Patients receiving 5 ml nebulized epinephrine had a significant increase of systolic and diastolic blood pressure at 40 and 180 min. Nebulized l-epinephrine at doses of 0.5, 2.5 and 5 ml demonstrated a lack of dose response in effect on PES and a modestly clinically significant increase in undesired side effects (heart rate and blood pressure) at higher doses.
- Revisão sistemática das escalas utilizadas para avaliação funcional na doença de Pompe(2012) SAVEGNAGO, Alana Karla; SILVA, Rosângela Maria da; JONHSTON, Cíntia; MARTINS, Ana Maria; MELO, Ana Paula L. de; CARVALHO, Werther Brunow deOBJECTIVE: To identify functional assessment scales used in Pompe disease (PD) and to describe their levels of evidence and grades of recommendation. DATA SOURCE: Systematic review of the functional assessment scales used in PD. Review conducted in the databases Medline, Lilacs, Cochrane Central Register of Controlled Trials (CCTR), and SciELO including articles (except review articles) published between 2000 and 2010. The key-words used in Portuguese and English were: glycogen storage disease type II, activities of daily living, assessment. The articles were classified according to their level of evidence and grade of recommendations. DATA SYNTHESIS: 14 studies assessing patients ranging from newborns to adults were included in the present review (total sample=449). The scales found in the literature were: Pediatric Evaluation of Disability Inventory (PEDI) and its adapted version for PD (Pompe-PEDI), Alberta Infant Motor Scale (AIMS), Rotterdam Handicap Scale (RHS), Functional Independence Measure (FIM), Gross Motor Function Measure (GMFM), and Peabody Developmental Motor Scales (PDMS-II). Most studies had level of evidence III because they were non-randomized studies. The grades of recommendation of the scales were C for AIMS and Pompe-PEDI, D for GMFM and PDMS-II; and E for RHS and FIM. CONCLUSIONS: Most functional assessment scales used in PD show low level of evidence and grade of recommendation. The scales showing the highest grade of recommendation (C) were the AIMS and Pompe-PEDI used in Pediatrics.
- Nutritional risk and anthropometric evaluation in pediatric liver transplantation(2012) ZAMBERLAN, Patricia; LEONE, Claudio; TANNURI, Uenis; CARVALHO, Werther Brunow de; DELGADO, Artur FigueiredoOBJECTIVE: To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. METHOD: Anthropometric evaluations of 60 children and adolescents after orthotopic liver transplantation, during the first 24 hours in a tertiary pediatric intensive care unit. Nutritional status was determined from the Z score for the following indices: weight/age, height/age or length/age, weight/height or weight/length, body mass index/age, arm circumference/age and triceps skinfold/age. The severity of liver disease was evaluated using one of the two models which was adequated to the patients' age: 1. Pediatric End-stage Liver Disease, 2. Model for End-Stage Liver Disease. RESULTS: We found 50.0% undernutrition by height/age; 27.3% by weight/age; 11.1% by weight/height or weight/length; 10.0% by body mass index/age; 61.6% by arm circumference/age and 51.0% by triceps skinfold/age. There was no correlation between nutritional status and Pediatric End-stage Liver Disease or mortality. We found a negative correlation between arm circumference/age and length of hospitalization. CONCLUSION: Children with chronic liver diseases experience a significant degree of undernutrition, which makes nutritional support an important aspect of therapy. Despite the difficulties in assessment, anthropometric evaluation of the upper limbs is useful to evaluate nutritional status of children before or after liver transplantation.
- Manejo do paciente no período perioperatório em neurocirurgia pediátrica(2012) MEKITARIAN FILHO, Eduardo; CARVALHO, Werther Brunow de; CAVALHEIRO, SergioPerioperative patient management in pediatric neurosurgery Objectives: To describe the main pathophysiological differences in neurosurgical procedures between children and adults; the main complications and adverse events resulting from pediatric neurosurgery reported in studies; the singularities in anesthetic and intraoperative management in several neurosurgical diseases; the more specific and common complications and their management in the most frequent pediatric neurosurgical procedures, as well as causes and treatment for the main complications found in children undergoing neurosurgery. Methods: A non-systematic review in literature databases PubMed, EMBASE, and SciELO was performed by using the keywords ""pediatrics"", ""children"", ""neurosurgery"", ""risk factors"", ""intraoperative complications"", and 'postoperative period"", as well as their matches in Portuguese and Spanish from January 2001 to January 2011, in addition to using important references from the selected material over any period of time. Results: The three procedures most commonly performed in children are hydrocephalus, craniostenosis repair, and brain tumor resection. Complications as fever, bleeding, metabolic disturbances (hyponatremia and hyperglycemia), brain swelling, and transient focal deficits (limb weakness, speech and swallowing disorders) are frequent, but their course is often towards prompt improvement. Up to 50% of children may have an uneventful evolution over the postoperative period. Special attention must be given to the prevention of postoperative infections and seizures with the use of a drug therapy that suits each case. Conclusion: The complexity of neurosurgical procedures in children is increasing, and observation and recognition of complications in pediatric intensive care units are fundamental. Anticipating complications in order to achieve an early treatment and adverse event prophylaxis can contribute to reduced morbidity and mortality and increased patients' safety.
- Acute pancreatitis in pediatrics: a systematic review of the literature(2012) MEKITARIAN FILHO, Eduardo; CARVALHO, Werther Brunow de; SILVA, Felipe DuarteObjective: To describe the main epidemiological, clinical, diagnostic and treatment aspects of children with acute pancreatitis. Sources: Systematic review of MEDLINE and SciELO databases in the last 5 years about acute pancreatitis in children, as well as consultation of relevant references on the texts obtained. Summary of the findings: Cases of acute pancreatitis in children have received growing attention in recent years, and an increase in the number of cases has been reported in several studies. The main etiologies in children involve biliary disease, drug-induced pancreatitis, recurrent hereditary pancreatitis and trauma, and up to 30% of cases have no defined etiology. The diagnosis is based on the combination of clinical and laboratory aspects with the increase of acinar enzymes and radiologic tests. Initial support treatment, with proper volume replacement and correction of the metabolic disturbances, besides specific nutritional therapy, are the fundamental points in the handling of acute conditions. Long term complications are unusual, and mortality rates are inferior to the rates for the adult population. Conclusions: The early diagnosis and the appropriate handling can contribute to a better outcome for the child with pancreatitis and to prevent the immediate and late complications related to the disease. More studies are required to better explain aspects related to the clinical and radiological diagnosis of pancreatitis in children, as well as aspects related to the nutritional therapy for this age group.
