- Knowledge and Practice of the Concept of Driving Pressure: A Survey of Pediatric Intensivists in Brazil(2019) JR, Jose Colleti; ARAUJO, Orlei; REZENDE, Felipe Caino de Oliveira; CARVALHO, Werther Brunow deThe objective of this study was to investigate the knowledge and clinical practices of Brazilian pediatric intensivists in relation to usage of the concept of driving pressure. Knowledge and practice patterns were assessed using a survey tool. The overall response rate was 22.8% (84 of 369); 69% of physicians responded that they had sufficient knowledge on the concept of driving pressure but only 56% correctly answered to specific knowledge questions about it. The majority of respondents (72.6%) claim to use this concept in their clinical practice although pediatric data are insufficient to routinely support the practice. This also suggests a good degree of knowledge translation from adult studies.

- Lymphocyte count as a sign of immunoparalysis and its correlation with nutritional status in pediatric intensive care patients with sepsis: A pilot study(2016) MANZOLI, Talita Freitas; DELGADO, Artur Figueiredo; TROSTER, Eduardo Juan; CARVALHO, Werther Brunow de; ANTUNES, Ana Caroline Barreto; MARQUES, Desiree Mayara; ZAMBERLAN, PatriciaOBJECTIVES: Developing malnutrition during hospitalization is well recognized worldwide, and children are at a relatively higher risk for malnutrition than adults. Malnutrition can lead to immune dysfunction, which is associated with a higher mortality rate due to sepsis, the most frequent cause of death in pediatric intensive care units (PICUs). The aim of this study was to investigate whether malnourished patients are more likely to have relative or absolute lymphopenia and, consequently, worse prognoses. METHODS: We enrolled 14 consecutive patients with sepsis whose legal representatives provided written informed consent. Patients were classified as normal or malnourished based on anthropometric measurements. As an additional evaluation of nutritional status, serum albumin and zinc were measured on the 1 st and 7 th days of hospitalization. Lymphocyte count was also measured on the 1 st and 7 th days. Clinicaltrials. gov: NCT02698683. RESULTS: Malnutrition prevalence rates were 33.3% and 42.8% based on weight and height, respectively. Laboratory analyses revealed a reduction of serum albumin in 100% of patients and reduction of zinc in 93.3% of patients. A total of 35% of patients had fewer than 500 lymphocytes/mm(3) on their first day in the PICU. Lymphocyte counts and zinc concentrations significantly increased during hospitalization. CONCLUSIONS: Nutritional evaluations, including anthropometric measurements, were not correlated with lymphocyte counts. Lymphocyte counts concomitantly increased with zinc levels, suggesting that micronutrient supplementation benefits patients with sepsis.

- Perioperative Factors Associated with Prolonged Intensive Care Unit and Hospital Length of Stay after Pediatric Neurosurgery(2011) MEKITARIAN FILHO, Eduardo; CARVALHO, Werther Brunow de; CAVALHEIRO, Sergio; HORIGOSHI, Nelson Kazunobu; FREDDI, Norberto AntonioObjectives: This study aims to describe the association between different postoperative complications and the length of hospital stay among children undergoing neurosurgical procedures. Methods: A retrospective cohort study was carried out between May 2004 and May 2009 in a tertiary community hospital. All postoperative complications following neurosurgical procedures and their association with the main outcomes [length of intensive care unit (ICU) and hospital stay] were investigated in a univariate and multivariate analysis. Results: The medical records of 198 patients treated during the study period were reviewed. The most frequently performed surgeries were ventriculoperitoneal shunting (16.7%), correction of craniosynostosis (30%) and brain tumor resections (28.3%). Of the 198 patients eligible for this analysis, 79 (39.9%) suffered from at least one complication. The most frequent complications were fever (30.3%), hypothermia (16%), postextubation laryngitis (15.1%) and postoperative bleeding (7%). Factors independently associated with a longer pediatric ICU stay were fever (odds ratio 1.39, 95% confidence interval 1.1-3.2; p = 0.001), laryngitis (odds ratio 2.24, 95% confidence interval 1.8-5.2; p = 0.001), postoperative bleeding requiring reoperation (odds ratio 1.8, 95% confidence interval 1.4-3.9; p < 0.001) and infection (odds ratio 3.71, 95% confidence interval 1.8-12.4; p = 0.033). Fever (odds ratio 2.54, 95% confidence interval 2-7.4; p = 0.001) and infection (odds ratio 11.23, 95% confidence interval 4-22.4; p = 0.003) were related to the total length of the patient's hospital stay. Conclusions: In this study population, most elective neurosurgical procedures were not associated with significant complications, and morbidity and mortality were low. Some complications significantly influenced patients' outcomes and should be monitored for early diagnosis. This study may improve our understanding and identification of postoperative outcomes in pediatric neurosurgery.

- Association between fluid creep and infection in burned children: A cohort study(2020) DITTRICH, Maria Helena M.; HOSNI, Nicole Dittrich; CARVALHO, Werther B. deIntroduction: Aggressive fluid resuscitation has been extensively discussed after the establishment of fluid creep phenomenon as a morbidity and mortality factor in burn children. Sepsis is currently the leading cause of death in survivors of burn shock. Objectives: To evaluate the association between fluid creep and infection in burn children exposed to two different fluid resuscitation strategies with the use of albumin. Methods: A cohort of 46 burn children with 15-45% of body surface area (BSA) admitted up to 12 h after the incident were evaluated. Patients from early albumin group (n = 23) received 5% albumin between 8 and 12 h from injury and patients from delayed albumin group (n = 23) received 5% albumin after 24 h. Outcomes analysed were development of fluid creep, length of stay in the hospital, number of surgery procedures and infection until hospital discharge. Results: Compared to the delayed group, patients that received early albumin had a shorter length of stay in the hospital (p = 0.007), less fluid creep (4.3% x 56.5%) (p < 0.001), less skin graft procedure (47.8% xd 78.3%) (p = 0.032) and less debridement (73.9% x 100%) (p = 0.022). Both length of stay in the hospital and fluid creep arising were associated with infection (p < 0.05). Conclusion: Fluid creep, surgery procedures and length of stay in hospital parameters showed better results in burn children treated with early albumin. Fluid creep and length of stay in the hospital were associated with infection, providing a negative prognosis.
