EFFICIENCY OF OXYGEN THERAPY BY HEAD BOX FOR ACUTE RESPIRATORY FAILURE IN INFANTS

Oxygen therapy is the main treatment method for acute respiratory failure in children. The method consisting in the administration of oxygen therapy by head box to infants is frequently used in pediatric practice. Objectives. To evaluate the effi ciency of oxygen therapy administered by head box to infants suffering from pneumogenic acute respiratory failure by comparing two methods for measuring hemoglobin oxygen saturation: in arterialized capillary blood and by pulse oximetry. Material and method. 30 infants suffering from pneumogenic acute respiratory failure were studied. We used a clinical appraisal score for acute respiratory failure, which appraises respiratory rate, nasal fl aring, recession, cyanosis, sensorial, before and after oxygen therapy. In arterialized capillary blood we measured partial pressure of oxygen and hemoglobin oxygen saturation, and we used an Automatic Blood Gas System analyzer. We also measured hemoglobin oxygen saturation using a pulse oximeter. Determinations were made before the initiation of oxygen therapy, and 30 minutes and 60 minutes after the initiation of oxygen therapy. Results. As compared to the baseline values, determined before the initiation of oxygen therapy, we recorded a statistically signifi cant improvement in the clinical score both after 30 minutes and 60 minutes from the initiation of oxygen therapy (p<0.001). The improvement was greater after 60 minutes. The increase in the partial pressure of oxygen was statistically signifi cant both at the 30 minute and 60 minute determination (p<0.001). Both methods of SaO2 measurement recorded statistically signifi cant increases (p<0.001) in this variable after 30 and 60 minutes, respectively. Conclusions. Oxygen therapy administered by head box improves acute respiratory failure appraised by clinical score. The administration of oxygen therapy by head box to infants signifi cantly increases the values of partial pressure of oxygen and hemoglobin oxygen saturation measured in capillary blood, as well as the values of hemoglobin oxygen saturation determined by pulse oximeter both after 30 minutes and after 60 minutes. The increases in the three parameters are larger after 60 minutes. There is statistically signifi cant concordance between the values of hemoglobin oxygen saturation determined in capillary blood and by pulse oximetry at all determinations

Endoscopic Grading as a Predictor to Develop Strictures in Corrosive Esophagitis in Children

Introduction. The incidence of corrosive esophagitis, also known as caustic esophagitis in children, is still increasing in developing countries, according to different clinical reports. Acids and alkalis are, in the same manner, involved in the pathogenesis of corrosive esophagitis in children. The aim of our study was to determine the incidence and endoscopic grading of corrosive esophagitis in a cohort of children from a developing country. Materials and methods. We performed a retrospective analysis of all pediatric patients who were admitted for corrosive ingestion at Pediatric Clinic II, Emergency Hospital for Children, Cluj-Napoca, over 10 years. Results. A total of 22 patients consisting of 13 (59.09%) girls and 9 boys (40.91%) were found in the present research. The majority of children lived in rural areas (69.2%). The results of laboratory tests were not well correlated with the degree of the injury. White blood cell counts over 20,000 cells/mm3, an increase in the C-reactive protein level and hypoalbuminemia were noticed only in three patients with strictures. The lesions were associated with increased levels of the pro-inflammatory cytokines, including interleukin (IL)-2, IL-5 and Interferon-gamma. Severe late complications such as strictures have been noticed in children with grade 3A injuries. The endoscopic dilation was done after the six months endoscopy. None of the patients treated with endoscopic dilation required surgical intervention for esophageal or pyloric perforation or dilation failure. The majority of complications (such as malnutrition) were noticed in children with grade 3A injuries. In consequence, prolonged hospitalization has been required. The second endoscopy (done six months after ingestion) revealed stricture as the most common late complication (n = 13, 60.60%: eight patients with grade 2B and five with grade 3A). Conclusion. There is a low incidence of corrosive esophagitis in children in our geographic area. Endoscopic grading is a predictor of late complications such as strictures. Grade 2B and 3A corrosive esophagitis are likely to develop strictures. It is crucial to avoid strictures and to prevent malnutrition
