Pediatric Sepsis Guidelines: summary for resource-limited countries

Justification: Pediatric sepsis is a commonly encountered global issue. Existing guidelines for sepsis seem to be applicable to the developed countries, and only few articles are published regarding application of these guidelines in the developing countries, especially in resource-limited countries such as India and Africa. Process: An expert representative panel drawn from all over India, under aegis of Intensive Care Chapter of Indian Academy of Pediatrics (IAP) met to discuss and draw guidelines for clinical practice and feasibility of delivery of care in the early hours in pediatric patient with sepsis, keeping in view unique patient population and limited availability of equipment and resources. Discussion included issues such as sepsis definitions, rapid cardiopulmonary assessment, feasibility of early aggressive fluid therapy, inotropic support, corticosteriod therapy, early endotracheal intubation and use of positive end expiratory pressure/mechanical ventilation, initial empirical antibiotic therapy, glycemic control, and role of immunoglobulin, blood, and blood products. Objective: To achieve a reasonable evidence-based consensus on the basis of published literature and expert opinion to formulating clinical practice guidelines applicable to resource-limited countries such as India. Recommendations: Pediatric sepsis guidelines are presented in text and flow chart format keeping resource limitations in mind for countries such as India and Africa. Levels of evidence are indicated wherever applicable. It is anticipated that once the guidelines are used and outcomes data evaluated, further modifications will be necessary. It is planned to periodically review and revise these guidelines every 3–5 years as new body of evidence accumulates.

Demographic profile and outcome analysis of a tertiary level pediatric intensive care unit.

Objective : To study the profile and outcome of children admitted to a tertiary level pediatric intensive care unit (PICU) in India.Methods : Prospective study of patient demographics, PRISM III scores, diagnoses, treatment, morbidity and mortality of all PICU admissions.Results : 948 children were admitted to the PICU. Mean age was 41.48 months. Male to female ratio was 2.95:1. Mean PRISM III score on admission was 18.50. Diagnoses included respiratory (19.7%), cardiac (9.7%), neurological (17.9%), infectious (12.5%), trauma (11.7%), other surgical (8.8%).196 children (20.68%) required mechanical ventilation. Average duration of ventilation was 6.39 days. 27 children (30.7 children /1000 admissions) had acute respiratory distress syndrome. Gross mortality was 6.7% (59 patients). PRISMIII adjusted mortality was directly proportional to PRISMIII scores. 49.5% of nonsurvivors had multiorgan failure. Average length of PICU stay was 4.52 +/−2.6 days. Complications commonly encountered Were atelectasis (6.37%), accidental extubation (2%), and pneumothorax (0.9%). Incidence of nosocomial infections was 16.86%.Conclusion : Our data appears to be similar with regards to PRISMIII scores and adjusted mortality, length of the PICU stay, and duration of ventilation, to previously published western data. Multiorgan failure remains a major cause of death. As expected, Dengue and malaria were common. Incidence of nosocomial infections was somewhat high. Interestingly, more boys got admitted to the PICU as compared to girls. Clearly more studies are required to assess the overall outcomes of critically ill children in India

Guidelines for treatment of septic shock in resource limited environments.

WHO 2005 data points to sepsis in form of pneumonia, diarrhea, and neonatal sepsis as major killers of children in the resource limited countries of Asia and Africa, However, currently there are no specific published guidelines for treatment of severe sepsis in resource limited circumstances. An expert panel drawn from all over India, met to discuss and draw guidelines for management of pediatric septic shock that are applicable to resource limited countries. The group evaluated strength of published data and expert opinion for clinical practice and feasibility of delivery of care at various levels of resource constraints, keeping in view unique patient population and limited availability of equipment and resources. Issues for discussion included simplified definitions and reliable clinical indicators of septic shock, fluid resuscitation, graded inotropic and vasopressor support, corticosteroid therapy, timing and indication for endotracheal intubation and use of positive end expiratory pressure/mechanical ventilation, initial empirical antibiotic therapy, correction of hypoglycemia and glycemic control, role of immunoglobulin, and blood and blood products. Evidence has been graded and levels of evidence indicated wherever applicable. The expert group recognized and listed potential barrier to implementation of existing American College of Critical Care Medicine guidelines for treatment of septic shock in resource limited countries, adopted simplified definitions of septic shock, tachycardia, tachypnea and hypotension, and developed step-wise algorithmic approach for treating septic shock. Evidence based treatment recommendations include early oxygen therapy, fluid resuscitation based on blood pressure, use of dopamine in fluid refractory shock, early use of antibiotics, early intubation and assisted ventilation, correction of hypoglycemia and emphasis on use of physical examination for achieving therapeutic endpoints. These interventions have brought the mortality down and can be easily applied even at primary and/or secondary level health facilities. Interventions recommended after above steps were based on consensus rather than evidence. These include stress dose steroid therapy, use of vasopressors and inodilators, and central venous pressure and echocardiography to guide fluid and vasoactive drug infusion, which require transfer to a pediatric intensive care unit. Strict glycemic control is not recommended. Evidence on benefit of several other interventions viz. use of vasopressin as vasopressor, use of intravenous immunoglobulins, renal replacement therapy, use of plasmapheresis etc. is emerging. The expert group observed that further research evaluating individual components of guidelines and relative benefit of each of these interventions in resource limited setting is needed, as also the benefit of adherence with standardized protocol. Pediatric sepsis guidelines suitable for resource limited settings are presented for resource limited settings. Several unresolved issues were identified for further research.

Intensive care unit acquired weakness in children: Critical illness polyneuropathy and myopathy

Background and Aims: Intensive care unit acquired weakness (ICUAW) is a common occurrence in patients who are critically ill. It is most often due to critical illness polyneuropathy (CIP) or to critical illness myopathy (CIM). ICUAW is increasingly being recognized partly as a consequence of improved survival in patients with severe sepsis and multi-organ failure, partly related to commonly used agents such as steroids and muscle relaxants. There have been occasional reports of CIP and CIM in children, but little is known about their prevalence or clinical impact in the pediatric population. This review summarizes the current understanding of pathophysiology, clinical presentation, diagnosis and treatment of CIP and CIM in general with special reference to published literature in the pediatric age group. Subjects and Methods: Studies were identified through MedLine and Embase using relevant MeSH and Key words. Both adult and pediatric studies were included. Results: ICUAW in children is a poorly described entity with unknown incidence, etiology and unclear long-term prognosis. Conclusions: Critical illness polyneuropathy and myopathy is relatively rare, but clinically significant sequelae of multifactorial origin affecting morbidity, length of intensive care unit (ICU) stay and possibly mortality in critically ill children admitted to pediatric ICU.

Recent advances in sepsis and septic shock.

Sepsis remains a common problem in all age groups. Recently surviving sepsis campaign has taken up a worldwide initiative by publishing international guidelines 2008 with a hope to disseminate information regarding management of sepsis for all age groups. This article presents a review of recent advances as they apply to pediatric age group supported by the available evidence with reference to standard definitions of pediatric sepsis and septic shock and management in the emergency room and pediatric intensive care unit.

Isolated severe bilateral bronchomalacia.

Airway malacia is uncommon condition having symptoms similar to common respiratory illnesses. Any child having persistent wheeze during infancy should be evaluated for airway malacia. The authors report a case of isolated severe bilateral bronchomalacia managed with tracheostomy and continuous positive pressure ventilation.

Bedside ultrasound and echocardiography by the pediatric intensivist: An evolving tool and a feasible option in a pediatric ICU.

Bedside ultrasound (BUS) and echocardiography are the evolving tools for pediatric intensivists, which are currently being used in many pediatric intensive care units to evaluate several disease processes, assist in procedural interventions, assess the complications related to those procedures, and perform an accurate and comprehensive assessment of a critically ill child at the bedside.[1,2] Transthoracic echocardiography has been used in adult patients to assess the volume status in the emergency room, though somewhat less commonly, in pediatric patients.[3]

Pachymeningitis in a young child responded to antitubercular therapy: a case report.

Pachymeningitis is a rare disease of diverse etiology mainly affecting the adult population. Only 4 pediatric cases have been reported till now. We report the youngest child with pachymeningitis from India. Our case responded very well to antitubercular therapy with near complete recovery. Antitubercular therapy can be considered in children from endemic countries with hypertrophic pachymeningitis before labeling their condition as idiopathic hypertrophic pachymeningitis.

Kawasaki disease—Atypical presentation

Kawasaki disease, an acute systemic vasculitis of unknown etiology, is the leading cause of acquired heart disease in children in many parts of the world. It predominantly affects children under 5 years of age and is diagnosed clinically by the presence of characteristic clinical signs. Atypical patients, often younger than 1 year of age, manifest few early signs, usually have an incorrect admitting diagnosis and suffer from high morbidity and mortality. We report the presentation, clinical course and follow -up of a 3-month-old infant with atypical Kawasaki disease.

Genetic Analysis in Bartter Syndrome from India

Bartter syndrome is a group of inherited, salt-losing tubulopathies presenting as hypokalemic metabolic alkalosis with normotensive hyperreninemia and hyperaldosteronism. Around 150 cases have been reported in literature till now. Mutations leading to salt losing tubulopathies are not routinely tested in Indian population. The authors have done the genetic analysis for the first time in the Bartter syndrome on two cases from India. First case was antenatal Bartter syndrome presenting with massive polyuria and hyperkalemia. Mutational analysis revealed compound heterozygous mutations in KCNJ1(ROMK) gene [p(Leu220Phe), p(Thr191Pro)]. Second case had a phenotypic presentation of classical Bartter syndrome however, genetic analysis revealed only heterozygous novel mutation in SLC12A gene p(Ala232Thr). Bartter syndrome is a clinical diagnosis and genetic analysis is recommended for prognostication and genetic counseling.
