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

Transfusion-related acute lung injury (TRALI) is a frequently under-diagnosed, although potentially fatal, condition that represents a leading cause of transfusion-related morbidity and mortality even in pediatric patients. Its main clinical features are characterized by rapidly evolving respiratory distress, hypoxia, pulmonary edema, and bilateral infiltrates on chest radiograph during or within 6 h of transfusion. We present a case of severe TRALI associated with myocardial stunning that occurred in a 14-year-old girl, and review the existing literature of pediatric TRALI. Our report suggests a potential role for NIV in the management of TRALI as the best profile both in terms of safety and effectiveness for hematologic patients.

ABSTRACT

Administration of drugs directly into the respiratory tree first was proposed a long time ago. Surfactant is the paradigmatic example of such therapies. Many other drugs have been used in the same way and further compounds are under investigation for this aim. In the last two decades, despite the wide number of drugs available for direct lung administration in critical care patients, few controlled data exist regarding their use in neonates and infants. This review will focus on drugs clinically available in a critical care setting for neonates and infants, including bronchodilators, pulmonary vasodilators, anti-inflammatory agents, mucolytics, resuscitative anti-infective agents, surfactants and other drugs. We provide an evidence-based comprehensive review of drugs available for intratracheal administration in paediatric and neonatal critical care and we examine possible advantages and risks for each proposed indication.

ABSTRACT

Young infants with measles requiring respiratory support have a significant risk for death and long-term complications. Even in developed countries, the occurrence of spontaneous air-leaks and acute respiratory distress syndrome (ARDS) still represent the most severe clinical presentation in early childhood, with a high fatality rate. A clinical series review from a tertiary university paediatric intensive care unit (PICU) was undertaken. During the 2006-2007 outbreak in Rome, Italy, a young infant presented with ARDS/spontaneous air-leak and needed aggressive ventilatory management and haemodynamic support. Both nebulised iloprost and intravenous pentoxifylline were administered during the acute hypoxaemic phase; the role of this pharmacologic approach in critically ill patients is still under debate. We observed four further cases of respiratory impairment requiring a non-invasive approach. Clinical-radiological findings ranged from interstitial pneumonia to bronchiolitis-like pictures. All patients were imported cases, representing an important epidemiological factor and future medical issue, though they were not malnourished nor affected by chronic diseases. We conclude that early respiratory assessment and timely PICU referral is of mainstem importance in the youngest infants with measles-induced respiratory failure. The protean nature of clinical presentation and the possibility of rapid respiratory deterioration should be highlighted, and infants from immigrant families may represent a susceptible high-risk group.

ABSTRACT

Severe hyperleukocytosis caused by acute lymphoblastic leukaemia (ALL) is associated with an increased risk of early death due to the intracranial haemorrhage. We report on a boy who presented with ALL with an extremely high leukocyte count, who developed neurological deterioration due to multiple intracerebral haemorrhages. Adequate measures for managing this medical emergency include appropriate supportive measures and initiation of therapy to prevent symptoms of leukostasis. Aggressive measures as a decompressive craniectomy should be considered to improve the poor outcome observed in this subset of patients.

ABSTRACT

The authors illustrate some relevant emerging topics in pediatric anesthesia. Endotracheal cuffed tubes have entered into routine clinical practice in younger patients. Concerns about tracheal stenosis were overcome when manufactures began to produce a new class of high volume, low pressure endotracheal tubes. Ultrasound-guided central venous cannulation helped anesthesiologists and intensivists to more efficaciously and safely perform the invasive monitoring required by ever more invasive surgical procedures. The utility of ultrasonography in peripheral nervous blocking has also been demonstrated. Better knowledge of the pathophysiology of both hypovolemic shock and coagulation dysfunction helped made it possible to face and successfully perform even major surgical procedures and treat more dramatic trauma. The introduction of devices to monitor anesthesia depth helped clinicians to better understand the pharmacodynamic effects of anesthetics, resulting in the maintenance of a more stable level of narcosis and the reduction of the incidence of awareness.

ABSTRACT

OBJECTIVE: Ultrasound guidance (USG) for internal jugular cannulation is the best solution in difficult settings where paediatric patients are involved. This is an outcome study on efficacy and complications of the USG for the internal jugular vein (IJV) cannulation in neurosurgical infants as well as an ultrasound study of anatomical findings of the IJVs in infants. DESIGN AND SETTINGS: A prospective study conducted in two Academic Neurosurgical hospitals. PARTICIPANTS: In 191 babies (body weight <15 kg), anatomical findings were studied. We performed CVC echo guided placement in 135/191 infants (weighting <10 kg). RESULTS: After a brief training period, both institutions adopted a common protocol and USG device. We obtained successful cannulation in all patients. Carotid puncture (1.5%) was the only main complication registered and minor complications were poor. Time required for cannulation was 12.5 +/- 5.7 min. Anatomical findings (in 191 patients) were IJV laterality in 34.6% cases, IJV antero-lateral in 59.7% and anterior in 5.7%. A linear relation was found between weight and internal jugular vein diameter even if R(2) = 0.43 and the model cannot be used to predict the exact size of the vein. In 62/135 babies weighting <10 kg, anatomical measurements were done in supine and Trendelemburg position. Trendelemburg position increases significantly (P < 0.001) IJV diameter, but not IJV depth. CONCLUSIONS: We considered ultrasound guidance as the first choice in infants because it can enhance IJV cannulation success, safety, and allows one to measure relationships and diameter of the IJV and optimise the central line positioning.

ABSTRACT

Sensitization to latex seems to occur more frequently in women than in men. Obstetric and gynecological surgical procedures have recently been shown to be a common setting for latex anaphylaxis. We analyzed all the cases of anaphylactic reactions during 1240 cesarean sections in 2004; the patients were questioned for risk factors and underwent allergy testing for drugs and latex. Four patients had anaphylaxis under spinal anesthesia and in all cases it was due to latex allergy. Reported symptoms included facial edema, profuse sweating, itching, generalized erythematous rash and hypotension. Only one patient manifested a severe reaction which included bronchospasm, dyspnea, tachypnea and anaphylactic shock, requiring orotracheal intubation and epinephrine. Our data showed a high incidence (1:310) of intraoperative latex anaphylactic reactions in the one-year study period. This may be related to the very specific population (all women) in a very specific setting (obstetrics). To prevent anaphylactic reactions during obstetric surgery it is important to identify potential risk factors to include, for example atopy, adverse reactions to foods and latex items. If latex allergy is confirmed or strongly suspected, patients should be managed in a latex-safe environment. Premedication with antihistamines and steroids might be useful to further reduce the risk. After the delivery, specific desensitization may represent a good therapeutic option.

ABSTRACT

The frequency of latex allergy in children requiring multiple surgery ranges from 16.7% to 65%. The aim of this study was to investigate the safety and efficacy of latex desensitization in a group of 10 patients with a history of multiple surgical procedures and clinically manifested allergy to latex. We selected 10 children (female-male ratio = 5:5), aged 4-16 yr (mean +/- s.d.: 9 +/- 4), with a history of multiple surgical procedures, adverse reactions to latex and positive skin test to latex and/or specific immunoglobulin E (IgE). Latex allergy diagnosis was confirmed by specific provocation tests (cutaneous, sublingual, mucous, conjunctival tests). Rush (4-day) sublingual desensitization was performed with increasing doses of latex extract (ALK Abellò) under patients' tongue until the highest dose of 500 microg of latex. A maintenance therapy (10 drops of undiluted solution three times a week) was recommended. During the 2-yr follow-up mean values of specific IgG4 and IgE, eosinophilic cationic protein and total IgE did not show significant variations. Patients did not manifest any adverse effect during the rush phase and only two patients manifested mild local symptoms during the maintenance therapy. All the challenges showed a reduction in terms of percentage of positivity and mean scores. All the patients showed a reduction of the mean individual score (p < 0.001). Furthermore patients who needed dental examination or surgery underwent such procedures without the occurrence of symptoms. Our preliminary results show sublingual desensitization to latex can be an important therapeutic tool in the management of young allergic patients requiring multiple operations.

ABSTRACT

INTRODUCTION: Anatomical hemispherectomy is frequently employed in the surgical management of pediatric patients with medically refractory epilepsy. MATERIALS AND METHODS: In this chapter, we review the historical evolution of this surgical procedure, outline the indications and the criteria for selecting surgical candidates and describe the important pre-operative evaluation of the surgical candidates. DISCUSSION: We provide a detailed description of our surgical technique, anesthesiological considerations, and post-operative care plan. Ultimately we analyze the most common complications associated with this procedure. CONCLUSION: Anatomical hemispherectomy performed in carefully selected pediatric patients with medically intractable epilepsy can be a safe and efficacious surgical procedure.

ABSTRACT

INTRODUCTION: Hemimegalencephaly (HME) is a quite rare malformation of the cortical development arising from an abnormal proliferation of anomalous neuronal and glial cells that generally leads to the hypertrophy of the whole affected cerebral hemisphere. The pathogenesis of such a complex malformation is still unknown even though several hypotheses are reported in literature. BACKGROUND: HME can occur alone or associated with neurocutaneous disorders, such as neurofibromatosis, epidermal nevus syndrome, Ito's hypomelanosis, and Klippel-Trenonay-Weber syndrome. The clinical picture is usually dominated by a severe and drug-resistant epilepsy. Other common findings are represented by macrocrania, mean/severe mental retardation, unilateral motor deficit, and hemianopia. The EEG shows different abnormal patterns, mainly characterized by suppression burst and/or hemihypsarrhythmia. Although neuroimaging and histologic investigations often show typical findings (enlarged hemisphere, malformed ventricular system, alteration of the normal gyration), the differential diagnosis with other disorders of the neuronal and glial proliferation may be difficult to obtain. Hemispherectomy/hemispherotomy is the most effective treatment to control seizure, and it also seems to provide good results on the psychomotor development when performed early, as demonstrated by the literature review and by the reported personal series reported here (20 children). The surgical therapy of HME, however, is still burdened by a quite high complication rate and mortality risk.
