Value of airway pH monitoring in determining the association between chronic cough and laryngopharyngeal reflux in children / 中国当代儿科杂志

OBJECTIVE@#To study the value of airway pH monitoring in determining the association between chronic cough and laryngopharyngeal reflux (LPR) in children.@*METHODS@#A total of 274 children with chronic cough who were treated from January 2016 to December 2019 were enrolled. The DX-pH detection system was used to conduct 24-hour airway pH monitoring. The association between chronic cough and LPR was analyzed.@*RESULTS@#Among the 274 children, there were 168 boys and 106 girls, with a median age of 62.8 months and a median airway pH value of 7.3. Of all the 274 children, 99 (36.1%) had LPR, and the incidence rate of LPR was 36.9% (62/168) in boys and 34.9% (37/106) in girls (@*CONCLUSIONS@#LPR is highly associated with the development of chronic cough, and airway pH monitoring may be a safe and effective method for the diagnosis of LPR.

Treatment of cutaneous injuries of neonates induced by drug extravasation with hyaluronidase and hirudoid

To analyze the effects of hyaluronidase and hirudoid treatment on drug extravasation in neonates. The medical records of 13 neonates with drug extravasation treated with hyaluronidase and hirudoid between August 1[st], 2010 and May 1[st], 2012 were analyzed retrospectively. The treatment procedure for drug extravasation adhered to the protocol in neonatal department The information including age, sex, weight, diagnosis, size of affected area, site of extravasation and treatment was collected. The extravasation injuries alleviated and the symptoms improved after treatment, no adverse drug effects were reported with use of hyaluronidase and hirudoid. The treatment appeared to be beneficial in the management of extravasations of various medications in neonates and may be useful in reducing the severity of cutaneous toxicosis. However, further studies with large samples are still needed to assess the effectiveness and safety of hyaluronidase and hirudoid

Evaluation and nursing of continuous blood purification therapy on acute respiratory distress syndrome in children / 中华实用儿科临床杂志

Objective To investigate the efficacy of continuous blood purification (CBP) in treatment of acute respiratory syndrome (ARDS) in children,and the methods as well as the key points in nursing care.Methods There were 97 cases of ARDS,and 18 cases were treated with CBP.The model for CBP was continuous veno-venous hemofiltration dialysis (CVVHDF) or high volume hemofiltration (HVHF).The observational index included arterial partial pressure of oxygen [pa(O2)],arterial partial pressure of carbon dioxide [Pa(CO2)],mechanical ventilation parameters,complications and side reaction during CBP.Results The pediatric critical illness score in CBP treatment group and non-CBP treatment group were (62.5 ± 25.2) and (78.1 ± 16.3) respectively,and the difference between the 2 groups was significant (P ＜ 0.05) ; the median of pediatric risk of score mortality Ⅲ score in CBP treatment group and non-CBP treatment group were 16(10-20) and 12(7-14),and the difference was significant between the 2 groups (all P ＜0.05).The average duration of CBP in 18 cases was 58 hours(12-232 hours),death occurred in 5 cases,and 2 cases of them were due to giving up treatment,the mortality was 27.8％ ;while in non-CBP treatment group,21 cases occurred death and the mortality was 26.6％.The difference of mortality between the 2 groups was not significant (P ＞ 0.05).Pa (O2)/fraction of inspired oxygen (FiO2) and dynamic compliance (Cdyn) were improved after 2-6 hours CBP,and the pulmonary exudation alleviated after 2 hours treatment.Mechanical ventilation parameters including FiO2,peak inspiratory pressure and positive end expiratory pressure were reduced.The complications related with CBP treatment included aggravating anemia,thrombopenia,lower body temperature,hemorrhage,oliguria,thick sputum,pain and dysphoria.No serious lethal complication was observed.Conclusions CBP treatment is a safe and effective rescue method for ARDS in children,it can reduce pulmonary edema,improve pa (O2)/FiO2 and Cdyn,and improve mechanical ventilation parameters.During CBP therapy,the key points include monitoring vital sign and the changes of hemodynamic,keeping body position nursing care well,tranquilizing,as well as maintaining the pipe unobstructed.
