Abstract Following the discovery that sodium transport and glucose transport are coupled in the small intestine, such that glucose accelerates solute and water absorption, highlighted oral hydration), along with other 20th-century milestones like the development of penicillin and viral cultures that preceded the polio vaccine; this opinion article refers to the participation of Costa Rica in the successful development of an applied research study on a priority health problem: oral rehydration in diarrhea caused by viruses.

Comparison Between Oral Rehydration and Intravenous Fluid Therapy Among Children under 5 Years with Acute Diarrhea with some Dehydration in the Emergency Department of the Children’s Hospital, Vientiane, Lao PDR / Lao Medical Journal

Background@#Worldwide, diarrhea is a common disease in children and is a problem that causes many children to become sick and die. Diarrhea is found to be the leading cause of death of children under 5 years of age, with 700,000 cases per year worldwide. The incidence of diarrhea is increasing in Laos.@*Objective@#To study oral rehydration and intravenous fluid therapy in children under 5 years of age with acute diarrhea with some dehydration in the Emergency Department of the Children’s Hospital, Vientiane, Lao PDR.@*Methodology@#This was cross-sectional descriptive study; data were collected by using questionnaire interview by doctors. The data entered by Epi-data with analysis by SPSS.@*Results@#Among 90 participants it was found that anxiety or irritability, sunken eyes, nausea, vomiting and flatulence were statistically significantly associated with outcome of treatment (p-value <0.05). More than half of the patients are male (52.2%), aged between 1-2 years and most (83.3%) had normal BMI values. In addition, 44.4% had a history of diarrhea for 2 days with 4 to 5 times a day in 34.4% and stools were watery in 57.8%. A number of participants (47.8%) had a history of previous diarrhea before the current illness and most of them had had it 3 times a year (41.9%). When comparing between oral rehydration and intravenous fluid therapy it was found that the children had no symptoms of anxiety or irritable (in 97.8% vs 77.8%), children with sunken eyes (in 91.1% vs 71.1%), children with vomiting (in 100% vs 64.4%) and children with flatulence (in 97.8% vs 80.0%). Excessive thirst and decreased skin turgor were not statistically different between before and after rehydration therapy (p-value >0.05).@*Conclusion@#The outcome of treatment with intravenous fluids was better than oral rehydration since former decreased vomiting, shortened hospital stays, lowered the costs and increase more parents ‘satisfaction. The oral dehydration therapy often increased the symptoms of flatulence.

Compliance with 14 day zinc therapy for acute diarrhoea: a prospective observational study

Background: Acute diarrheal diseases remain a leading cause of global morbidity and mortality in young children. The effective implementation of provision of zinc in addition to low osmolarity ORS remains very poor.Methods: A prospective observational study was done to determine compliance with zinc therapy on 103 children aged between two months to five years with acute gastroenteritis. They were started on WHO ORS and zinc in the form of syrup (20 mg/day in those >6 months of age and 10mg/day in those <6 months of age) and advised to continue for 14 days. Further episodes of diarrhea was considered as the primary outcome variable. Number of days zinc taken was considered as the primary explanatory variable. p-value <0.05 was considered statistically significant.Results: The mean age was 19.49'14.41 months. The compliance to complete 14-day zinc therapy was 62.14%.' The mean number of days zinc was taken was 11.28'3.81 days. In 11.65% of participants, there was further episodes of diarrhea. The main reasons for discontinuation were diarrhea stopped (45%), Ignorance (37.5%), URI (12.5%).Conclusions: Findings indicate that the syrup formulation is acceptable, but further efforts are required to enhance adherence. These findings also highlight the importance of guiding in ensuring adherence to zinc duration while also addressing the tendency of caregivers to terminate treatment once a child appears to have recovered from an acute diarrheal episode.

Knowledge and practices among caregivers in cases of persisitent diarrhoea in children of age group 6 months-12 years

Background: Persistent diarrhoea has a variety of infectious and non-infectious etiology and it seriously affects the growth and development of children. The objective of the is to the identify the knowledge and practices prevalent amongst caregivers of children to understand environmental and behavioral risk factors and their interactions associated with the disease and its management.Methods: It is a hospital based cross-sectional study which included 70 children in the age group 6 months-12 years admitted in a tertiary care center at Bhopal over a period of one year with complaints of loose stools lasting for more than 14 days. A pre-tested questionnaire was used as a data collection tool for face-to-face interviews with the mothers or caretakers of the cases. Statistical analysis was done using Statistical Package of Social Science (SPSS Version 20; Chicago Inc., USA). Data comparison was done by applying specific statistical tests to find out the statistical significance of the comparisons.Results: Most of children's mother were Illiterate, 27.1% were educated till primary school and only 5.7% were graduate. Out of 70 cases, most of 51(72.8%) were have understanding that drinking untreated water is a risk factor, only 11(15.7%) understands the value of filtered water and 8(11.4%) know the importance of doing boiling. Most of 46(65.7%) were using open field for sanitation and only 11(15.7%) were using toilets at home. 42(60.0%) were having the habit of hand washing before taking meal.'Conclusions: Community education about the prevention and management of diarrhoea will reduce the mortality and morbidity associated with persistent diarrhoea.

Prognostic significance of initial management of childhood diarrhoea in rural areas: an observational study

Background: To identify current evidence in order to guide scaling up of initial management of diarrhoea among children of age group 2-60 months in rural areas of the country.Methods: This hospital based cross sectional study included all children 2 months to 60 months of age admitted with chief complains of loose stools in the last 7 days over a period of one year. A pre-tested questionnaire was used as the data collection tool and face to face interviews were conducted on mothers of children.' All the data were analyzed using IBM SPSS version 20 software. Chi-square/Fisher Exact/ Student t-test and ANOVA test has been used. Significance was assessed at 5%.Results: Data showed the use of antibiotic in 55.9% cases, IV fluids in 50.3%, ORS in 6.7%, zinc in 2.0% and blood transfusion in 13.8% cases as an initial management of diarrhoea in peripheral health care centers. Of these, 37.6% cases were severely dehydrated, and 8.14% cases were in shock at the time of admission. 10.1% mothers did not intervene in the first 3 days of the disease whereas 45.2% consulted some health care center only in the later part. 4.5% cases expired after admission of which 69% were malnourished.Conclusions: This study summarizes the importance of initial management of a child with diarrhoea in defining the further course of the disease and also the failure of effective promotion and propagation of the most appropriate and cost-effective therapy (ORS and Zinc) for diarrhoea in this part of the country. Pre-existing malnutrition further complicates the situation.

Knowledge, attitude and practices of childhood diarrhoea among mothers of children under five years of age: a cross sectional study

Background: Diarrhoea is an important communicable disease which can be prevented by proper hygiene and other simple practical measures. We assessed the knowledge, attitude and practices among mothers regarding childhood diarrhoea in a secondary care hospital in Dimapur, Nagaland.Methods: Cross-sectional observational study conducted over a period of one year including 449 mothers in the age group <45 years with atleast one child under 5 years of age using an interviewer administered, pilot tested, semi-structured questionnaire under the following as categories demography, knowledge, attitude and practices.Results: 97.8% had good knowledge regarding causes and prevention of diarrhoea, 65% had good knowledge regarding the management of diarrhoea while 31% mothers had moderate knowledge. 98% mothers had good attitude but only 17.8% had good practice scores. Multivariate regression analysis showed education > class 10 and residence in urban area were significantly associated with good knowledge and education >class 10, age of mothers ≥29 years, employed mothers, family income Rs. ≥28000 were significantly associated with good practice.Conclusions: Good knowledge and attitude regarding diarrhoea prevention and management among our study population did not translate to good practice. These could also be due to the lower knowledge about management of diarrhoea. Widespread prevalence of wrong practices in the community like irrational use of antibiotics could also have resulted in low practice scores. The gaps between knowledge and attitude and practices among the mothers need to be addressed.

Knowledge, attitude and practice regarding diarrhoea and its prevention and the use of oral rehydration therapy among mothers of children under the age of five visiting a tertiary care hospital in Mangalore, India

Background: Diarrheal diseases remain the second most leading cause of mortality and morbidity next to pneumonia among under-five mortality globally, contributing to 1/5th of child deaths.Methods: Cross sectional hospital based questionnaire study conducted among 200 mothers of children within the age group of 6-60 months with diarrhoea attending the paediatric outdoor or treated in the paediatric indoor (OPD) at YMCH hospital using personal interview method. Filled up questionnaires was collected and was attached along with the filled up proforma.Results: Of 200 mothers, 24.3% knew the correct meaning of diarrhoea, with 73.8% of them not knowing the correct cause of diarrhoea. Only 44.3% knew that it could be prevented. Majority 88.7% did not know to look for signs of dehydration. Less than half of the mothers had only heard of ORT. By using c2-test, preparation ORS was found to be associated with the mother's education (p=0.04) proving that knowledge is better among those mothers with formal education. No association was found between ORS preparation and age of the mother (p=0.229), religion (p=0.342), and gender of the child (p=0.061).Conclusions: The findings of this research indicate that only 73.8% of the mothers had knowledge regarding the cause of the diarrhoea and less than half 11.3% has only heard and used ORT properly.

Comparison of Health Education, Oral Rehydration Solution, Metoprolol and Midodrine Intervention in Children with POTS

Introduction: The postural orthostatic tachycardia syndromeis heterogeneous group of disorder. When a healthy individualstands up, gravity causes about 10%-15% of his or her bloodto settle in the abdomen or limbs. This pooling of bloodmeans that less blood reaches the brain, the result of whichcan be a feeling of lightheadedness, darkening of vision, oreven fainting. Hence, the aim of the present study was toevaluate the clinical features and the effectiveness of nonpharmacological and pharmacological treatment in patientswith POTS.Material and Methods: A retrospective medical recordanalysis of the patients referred to pediatric cardiology unitof our Second Xiangya Hospital of Central South Universitysince June 2003 to February 2010 was done. This studyincluded 33 children patients aged 6 to 16 years old among17 male (mean 10.62±2.88 years) and 16 female (mean11.81±1.64 years) after medication within 14 days to 6 monthswith follow up record.Results: The most common presenting symptoms of POTSwere found to be dizziness or light-headedness (66.66%)followed by chest tightness (30.30%), syncope (27.27%),headache (24.24%) and pallor (24.24%) respectively. About75.5% of children patients met diagnostic criteria for POTSduring 5 to 10 minute of HUTT. There was significant statisticdifference in heart rate between before and after treatment oftotal patients during 5 and 10 minute of HUTT (P<0.05). Theoverall improvement found in 24(72.72%) patients whereas9(27.27%) patients not respond to the given treatment regimen.Conclusion: The most common presenting symptom of POTSwas dizziness or light-headedness. Most of the patients meetdiagnostic criteria for POTS during 5 to 10 minute durationof HUTT. Health education, ORS, propranolol and midodrinewere effective in treatment of POTS and helpful to diminishthe upright tachycardia. Whereas health education and healtheducation with midodrine hydrochloride treatment methodwere more likely effective than health education with ORSand health education with metoprolol method

Knowledge, attitude and practices of oral rehydration therapy among mothers coming to tertiary care centre

Background: Diarrhoea is a major cause of morbidity and mortality among under-five children. Correct knowledge regarding oral rehydration therapy (ORT) helps prevent morbidity and mortality due to diarrhoea. The objective of this study is to assess the knowledge, attitude and practice of mothers of under-five children regarding ORT and home management of diarrhoea.Methods: Study period from December 1st, 2017 to December 31st, 2017, total of 200 mothers were enrolled in this study. The data was entered in Microsoft excel sheet and percentages were calculated.Results: 95% of mothers were aware about ORS. ORS was given by parents on own in16%, 55% were advised by doctor. Only 60% knew how to prepare ORS correctly. About 45.7% had used bottle to give ORS and 55.3% used cup and spoon. About 67.9% had knowledge of quantity of ORS to be given during diarrhoea episode. Exclusive breast feeding was practised in 86% of mothers till 6 months of age. Misconceptions about the use of ORS were seen in 60% and more among illiterates. About 21% mothers' felt ORS should be stopped if diarrhoea continues. Only 5% of mothers felt ORS can be given even if child has vomiting. About 9% mothers felt no fluids should be given during diarrhoea.Conclusions: Mothers' knowledge and attitude on use of ORS in diarrhoea need to be improved.

Preventive oral rehydration salts Ⅲ could protect intestinal function in rats with exertional heatstroke / 中华危重病急救医学

Objective To observe the damage of various organs of rats with exertional heatstroke (EHS), and to investigate the protective effect of oral rehydration salts Ⅲ (ORSⅢ) on multi-organ function in rats with EHS. Methods Fifty-one male Sprague-Dawley (SD) rats were randomly divided into four groups by random digit table: normal control group (n = 13), EHS group (n = 13), EHS+water group (n = 12), and EHS+ORSⅢ group (n = 13). All rats in the EHS groups received adaptive training for 7 days before the experiment. On the 8th day, the rats of EHS+water and EHS+ORSⅢ groups were orally given 20 mL/kg water or ORSⅢ 30 minutes before the experiment. No pretreatment was performed in the EHS group. EHS model was reproduced by forcing rats to run under hot environment. The rats which refused to exercise and which core temperature > 40.5 ℃ were considered as the onset of EHS. The rats in the normal control group were exposed to room temperature (25±2) ℃ and humidity (50±5)% without any treatment. Six hours later, blood of inferior vena cava was collected, and the levels of serum MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH), alanine transaminase (ALT), aspartate transaminase (AST), serum creatinine (SCr), blood urea nitrogen (BUN), serum potassium, serum sodium and serum chloride were determined by automatic chemical analyzer. Serum intestinal fatty acid-binding protein (I-FABP) was determined by enzyme linked immunosorbent assay (ELISA). Results The levels of LDH, ALT, AST, BUN, serum sodium and serum chloride in the EHS group were significantly higher than those in the normal control group [LDH (U/L): 1 220±427 vs. 837±485, ALT (U/L): 138 (97, 164) vs. 37 (33, 42), AST (U/L): 409 (380, 566) vs. 86 (78, 104), BUN (mmol/L): 11.7 (9.6, 13.2) vs. 5.9 (5.5, 6.1), serum sodium (mmol/L): 148.0 (143.5, 154.5) vs. 139.0 (138.0, 140.5), serum chloride (mmol/L): 100.9±2.3 vs. 97.3±1.4, all P < 0.05], but no significant difference in CK-MB, SCr or serum potassium could be found [CK-MB (U/L): 1 280±373 vs. 1 379±480, SCr (μmol/L): 38.2±7.5 vs. 35.5±6.3, serum potassium (mmol/L): 5.5 (4.4, 6.2) vs. 4.7 (4.4, 4.9), all P > 0.05]. In the EHS+ORSⅢ group, only serum potassium level was significantly lower than that in the EHS group [mmol/L: 4.0 (3.7, 4.4) vs. 5.5 (4.4, 6.2), P < 0.01], while no significant difference in other parameters was found between the EHS+ORSⅢ group and the EHS group as well as the EHS+water group. Serum I-FABP level in the EHS group was significantly higher than that in the normal control group [μg/L: 36.90 (29.10, 45.00) vs. 11.39 (0.31, 20.80), P < 0.01]. Serum I-FABP level in the EHS+water and EHS+ORSⅢ groups were notably lower than that in the EHS group [μg/L:24.19 (20.00, 28.36), 0.31 (0.31, 5.58) vs. 36.90 (29.10, 45.00), both P < 0.01], additionally, I-FABP level was much lower in the EHS+ORSⅢ group (P < 0.01). Conclusions EHS could lead to liver, intestinal barrier dysfunction and electrolyte disturbance. Pre-treatment of ORSⅢ could alleviate the intestinal dysfunction and electrolyte disorder caused by EHS in rats. It can lower the serum potassium to some extent. However, ORSⅢ failed to protect liver from EHS.

La atención primaria de salud y la salud materno infantil

The Primary Health Care strategy introduced concepts which sought to revolutionize the way how to achieve Health for All at the global level. The Declaration of Alma Ata was a prelude to initiatives and global plans that sought compromise to States and society in achieving access to health equity. The Summit of Action for Children and the Meeting of the Millennium, which agreed health targets to achieve by year 2015 were inspired by the concepts included in Primary Health Care. While it is true that the purposes lying below the postulates in Alma Ata were not reached, there was remarkable progress in aspects related to the Mother and Child Health. The Selective Primary Healthcare inspired the so-called "Revolution for the Child Survival", which identified the main causes of the 15 million deaths in children recorded at the global level at the beginning of the Decade of the eighties of the last century, as well as the simple, low-cost interventions based on the evidence shown to be effective in the prevention of this "silent emergency" represented by the avoidable child deaths. Product of these interventions related to children health and the subsequent inclusion of interventions for the prevention of the 500 000 preventable maternal deaths recorded worldwide at the beginning of this century, has achieved remarkable progress at global level. Peru was one of the countries of the Americas that showed greater progress in reducing maternal and infant mortality. This article seeks to find an explanation of procedures and processes that allowed these achievements at the global level and in Peru, inspired by the principles proposed by the Primary Health Care strategy.

La estrategia Atención Primaria de la Salud introdujo conceptos que buscaron revolucionar la forma como se aspiraba lograr la Salud para Todos a nivel global. La declaración de Alma Ata fue un preludio de iniciativas y planes globales que buscaron comprometer a los Estados y a la sociedad en alcanzar el acceso a la salud con equidad. La Cumbre de Acción por la Infancia y la Reunión del Milenio, en la que se acordó las metas de salud a lograr el año 2015, estuvieron inspiradas en los conceptos incluidos en la Atención Primaria de la Salud. Si bien es cierto, los propósitos que subyacían a los postulados recogidos en Alma Ata no fueron alcanzados, sí hubo notables progresos en aspectos relacionados con la salud Materno Infantil. La Atención Primaria Selectiva de la Salud, inspiró la llamada ‘Revolución por la Supervivencia Infantil, que identificó las principales causas de las 15 millones muertes en niños, que se registraban a nivel global a inicios de la década de los años 80 del siglo pasado, así como las intervenciones sencillas, de bajo costo y basadas en la evidencia que habían mostrado ser efectivas en la prevención de esta ‘emergencia silenciosa que representaban las muertes infantiles evitables. Producto de estas intervenciones relacionadas con la salud infantil y la posterior inclusión de intervenciones para la prevención de las 500 000 muertes maternas evitables que registraba el mundo a inicios del presente siglo, se ha logrado notables progresos a nivel global en estos propósitos. El Perú fue uno de los países de las Américas que mostró mayores progresos en la reducción de la mortalidad materna y en la niñez. El presente artículo busca encontrar una explicación de las intervenciones y procesos que permitieron estos logros a nivel global y en el Perú, inspirados en los postulados propuestos por la estrategia de la Atención Primaria de la Salud.

Comparison of curative effect and serum electrolytes between different oral rehydration salts in treatment of neurally mediated syncope children / 中南大学学报(医学版)

Objective:To compare the curative effect and the changes of serum electrolytes between oral rehydration salts (ORS) Ⅰ and ORS Ⅲ treatment in neurally mediated syncope children.Methods:The children with the symptom of unexplained syncope and pre-syncope were collected in Second Xiangya Hospital from May 2014 to May 2017.After head-up tilt test (HUTT),their serum electrolytes levels were examined.Children who were positive in the HUTT received ORS (ORS Ⅰ or ORS Ⅲ) and health education.Subjects were randomly divided into an ORS Ⅰ group (n=27) and an ORS Ⅲ group (n=49).Results:There was no statistical significance in sex,age,height,body mass,initial diagnosis and re-diagnosis interval between the 2 groups (P＞0.05);the total efficiency after ORS Ⅲ and ORS Ⅰ treatment were 79.59％ and 62.96％,respectively,with no statistical significance (x2=2.483,P＞0.05);the HUTT negative conversion rate after ORS Ⅲ and ORS Ⅰ treatment were 51.02％ and 48.16％,respectively,with no statistical significance (x2=0.058,P＞0.05);before treatment,the serum sodium [(140.20±2.26) mmol/L vs (138.39±2.72) mmol/L;t=2.856,P＜0.05] in the ORS Ⅲ group was higher than that in the ORS Ⅰ group,the serum phosphorus [(1.46±0.19) mmol/L vs (1.65±0.29) mmol/L;t=3.146,P＜0.05] in the ORS Ⅲ group was lower than that in the ORS Ⅰ group;after treatment,the serum sodium [(140.31±2.01) mmol/L vs (138.88±2.08) mmol/L;t=2.692,P＜0.05] and serum calcium [(2.31±0.09) mmol/L vs (2.24±0.11) mmol/L;t=2.696,P＜0.05] in the ORS Ⅲ group were higher than those in the ORS Ⅰ group,the serum phosphorus [(1.45±0.16) mmol/L vs (1.61±0.25) mmol/L;t=3.128,P＜0.05] in the ORS Ⅲ group was lower than that in the ORS Ⅰ group;after ORS Ⅲ treatment,there was no statistical significance in serum electrolytes between HUTT positive group and HUTT negative group (P＞0.05);after ORS Ⅰ treatment,the serum calcium [(2.29±0.10) mmol/L vs (2.19±0.10) mmol/L;t=2.501,P＜0.05]and serum phosphorus [(1.71±0.24) mmol/L vs (1.50±0.21) mmol/L;t=2.392,P＜0.05] in HUTT positive group were higher than those in HUTT negative group.There was no statistical significance in serum sodium,potassium,magnesium,and chloride (P＞0.05);there was no statistical significance in serum electrolytes between pre-treatment and post-treatment in the ORS Ⅰ group and the ORS Ⅲ group (P＞0.05);there was no statistical significance in serum electrolytes between vasovagal syncope and postural orthostatic tachycardia syndrome in the ORS Ⅰ group and the ORS Ⅲ group before ORS treatment (P＞0.05).Conclusion:The ORS Ⅲ and ORS Ⅰ have the similar efficacy in the treatment of children with neurally mediated syncope.ORS Ⅲ is easier to be accepted by children than ORS Ⅰ,with better compliance.

Costos de la rehidratación oral y nasogástrica comparadas con la rehidratación endovenosa en niños con diarrea en Colombia / Costs of oral and nasogastric rehydration compared to intravenous rehydration in children under 5 years of age with diarrhea in Colombia

RESUMEN Objetivo Evaluar los costos de las terapias de rehidratación oral (TRO) y de rehidratación nasogástrica (TRN) comparadas con la terapia de rehidratación endovenosa (TRE) para corregir la deshidratación por diarrea en niños. Metodología Análisis de minimización de costos desde la perspectiva del Sistema de Salud colombiano comparando TRO (seguida de TRN ante falla de la TRO), con la TRE. El horizonte temporal fue la duración de la rehidratación. La medida de efectividad se extrajo de una revisión sistemática de literatura. Para determinar costos, se construyó un caso típico y un árbol de decisiones, a partir de revisión de guías e historias clínicas, validado con expertos. Los costos unitarios se obtuvieron de bases de datos colombianas. Costos fueron calculados en pesos colombianos (COP) y dólares americanos (USD). Se realizaron análisis de sensibilidad de una y dos vías. Resultados La TRO y la TRE son similares en efectividad para prevenir hospitalización y lograr rehidratación. En el caso base, el costo de la TRO fue $91,221COP (40.5 USD) y para TRE $112,944COP (50.14USD), es decir, un ahorro de $21,723 COP (9.64 USD). En los análisis de sensibilidad por regímenes de aseguramiento y complejidad del hospital, la TRO suele ser la estrategia menos costosa. Discusión Ambas intervenciones son similares en efectividad, pero la TRO, seguida de TRN ante falla de la primera resulta menos costosa que la TRE. La TRO es recomendable como primera opción para corregir la deshidratación. Deberían continuarse esfuerzos por implementar TRO y TRN en los servicios de salud en Colombia.(AU)

ABSTRACT Objective To evaluate the costs of oral rehydration therapy (ORT) and nasogastric rehydration therapy (NRT) compared with intravenous rehydration therapy (IRT) to treat dehydration in children under 5 years of age with diarrhea. Methodology Cost-minimization analysis from the perspective of the Colombian Health System, comparing ORT, (followed by NRT when ORT fails), with IRT. The time horizon was the duration of rehydration. The effectiveness measure was obtained from a systematic review of the literature. To determine costs, a typical case was created based on current guidelines and medical records; this case was validated by experts. Unit costs were obtained from Colombian databases and were provided in Colombian pesos (COP) and US dollars (USD) for 2010. One- and two-way sensitivity analyzes were performed. Results ORT and ERT are similarly effective to prevent hospitalization and to achieve rehydration. In the base case, the expected cost of ORT was $91,221 COP (40.5 USD) and for IRT was $112,944 COP ($50.14 USD), saving $21,723 COP ($9.64 USD) per case. In the sensitivity analyzes by health insurance and hospital level, ORT is often the least costly strategy. Discussion Both interventions are similarly effective, but ORT, followed by NRT when ORT fails, is less costly than IRT. ORT is recommended as the first option to treat dehydration since it is effective and less expensive. Efforts should be continued to implement TRO and NRT in the health services of Colombia.(AU)

Determination of Total Chloride in Oral Rehydration Salt Powder (Ⅲ) by Ion Chromatography / 中国药师

Objective:To establish a method for the determination of total chloride in oral rehydration salts powder (Ⅲ) by ion chromatography (IC). Methods:The analysis was performed on an IonPac AS 14A (250 mm × 4 mm) column with an IonPac AG 14A (50 mm × 4 mm) guard column and 9mmol·L-1 Na2 CO3 solution as the mobile phase. The flow rate was 1. 0 ml·min-1 with isocratic elution and the sample size was 25 μl. The suppressor was AERS 500(4mm) with 45mA suppression current, and an ECD was used for the detection. The quantity of chloride ion ( Cl-1 ) was calculated by the peak area with an external standard method. Re-sults:The linear range of Cl-1 was 0. 05-20. 00 mg·L-1(r=0. 9999);the recovery was 98. 89％(RSD=0. 56％, n=6). Conclu-sion:The results demonstrated that the method has the advantages of high sensitivity, simple sample pretreatment, promising accuracy and good reliability, which is suitable for the determination of total chloride in oral rehydration salt powder (Ⅲ) .

Therapeutic effect evaluation of oral rehydration salts [Ⅰ] on autonomic nerve mediated syncope in children with different hemodynamic patterns / 中华实用儿科临床杂志

Objective To explore the effects of oral rehydration salts [Ⅰ] (ORS Ⅰ) for autonomic nerve mediated syncope(NMS) in children with different hemodynamic patterns.Methods A total of 105 patients with unexplained syncope and prodromal symptoms of syncope who were confirmed as NMS by head-up tilt table test(HUTY) and treated in the Department of Pediatric Cardiovasology,Children's Medical Center,the Second Xiangya Hospital,Central South University,from March 2012 to February 2015.Their ages were from 4 to 18 years old,the average age was (11.96 ± 2.86) years old.Totally 73 cases were diagnosed as vasovagal syncope (VVS) (46 cases were vasodepressor type,27 cases were VVS mixed type or cardioinhibitory type),while 32 cases were diagnosed as postural orthostatic tachycardia syndrome(POTS).Simple random method was used to divide them into conventional therapy (health education and tilt training) plus ORS Ⅰ group (55 cases),and conventional therapy group (50 cases).Patients were followed up for 6-25 (14.82 ± 6.13) months.The recurrence of syncope and review of HUTT outcome assessment in 6 months,treatment was studied to evaluate short-term efficacy of 2 different therapies for NMS in children with different hemodynamic patterns.Taking recurrence of syncope as outcome events,Kaplan-Meier curves were drawn to compare long-term efficacy of different therapies in treating NMS children.Results There was no statistical difference in the short-term efficacy among the different hemodynamic patterns when treated with conventional therapy plus ORS I,or conventional therapy(all P ＞ 0.05).The cumulative efficiency of the conventional therapy plus ORS Ⅰ was superior to that of the conventional therapy for NMS children through the long-term follow-up study (74.5％ vs.52.0％,x2 =14.424,P ＜ 0.01).Patients with vasodepressor patterns had a better response than those with mixed or cardioinhibitory patterns to conventional therapy plus ORS I (90.0％ vs.61.1％,x2 =4.435,P ＜ 0.05).Conclusions Compared with VVS mixed type or cardioinhibitory type,children with VVS vasodepressor patterns are more appropriate to take ORS I as initial treatment.

Objective To explore the changes in serum and urine electrolytes of children with neurally media-ted syncope (NMS)after oral rehydration salts (ORS)[Ⅰ]treatment.Methods The study group included 135 patients [60 male and 75 female,aged 4 -16 years,average of (10.20 ±2.68)years old]with unexplained syncope and prodro-mal symptoms of syncope in our hospital between May 2014 and April 2015.The patients underwent head -up tilt test (HUTT),and completed serum electrolytes and 24 -hour urine electrolytes,and the serum electrolytes and 24 -hour u-rine electrolytes in different hemodynamic type of HUTT were compared.Positive HUTT patients were treated with health education and ORS[Ⅰ],while negative HUTT patients were received health education.Then 21 -154(42.63 ±27.71) days later,the patients returned to hospital,for the inquiry of symptom improvement,and review of HUTT,24 -hour urine and serum electrolytes.Results (1)The total effective rate of ORS[Ⅰ]treatment was 62.96% (17 /27 cases),while negative conversion rate of HUTT was 48.15% (13 /27 cases).(2)There was no significant difference in serum electro-lytes,24 -hour urine electrolytes or 24 -hour urine volume between HUTT positive group and negative group during the first visit (all P >0.05).(3)In return visit,serum calcium [(2.30 ±0.10)mmol/L vs (2.20 ±0.09)mmol/L,t =2.72,P 0.05).(4)24 -hour urine sodium [(159.06 ±72.76)mmol/24 h vs (118.97 ±52.75)mmol/24 h,t =2.712,P 0.05).(5)There was no significant difference in serum elec-trolytes,24 -hour urine electrolytes or 24 -hour urine volume between vasovagal syncope group and postural orthostatic tachycardia syndrome group during the first visit(all P >0.05).Conclusions ORS[Ⅰ]treatment can obviously increase the 24 -hour urine sodium,24 -hour urine chloride in children with NMS.ORS[Ⅰ]is an effective therapy for NMS.

Pilot Study for Safety and Efficacy of Newly Developed Oral Carbohydrate-Rich Solution Administration in Adult Surgery Patients

PURPOSE: In surgical procedures under general anesthesia, 6 to 8 hours of a nulla per os (NPO; nothing by mouth) has been regarded as essential for prevention of respiratory complication such as aspiration. However, recent studies have reported that oral intake of water and other clear fluids up to 2 hours before induction of anesthesia does not increase respiratory problems. The purpose of this pilot study is to investigate the safety and efficacy of a newly developed carbohydrate-rich solution in elective hernia repair surgery patients. METHODS: A group of 30 adult patients scheduled for elective surgeries under general anesthesia were enrolled. The enrolled study group of patients was permitted to drink a carbohydrate-rich solution until two hours before the operation without volume limitation. Respiratory complication was investigated in the patients using the carbohydrate-rich solution until two hours before induction of general anesthesia. The feelings of thirst, hunger sense were measured pre- and post-operatively. In addition, hoarseness of voice, nausea and vomiting were investigated post-operatively. Satisfaction regarding the short time of fasting was measured. Visual analogue scale (VAS) was used for measurement of these six variables. RESULTS: No patients showed serious respiratory complication such as dyspnea, desaturation. Eight of 30 study group patients complained of mild hoarseness. Most symptoms of hoarseness were mild, with VAS score less than 3 out of 10. Two patients complained 5 out of 10. Six patients felt nausea and 1 patient had vomiting. Pre/post-operative hunger sense and thirst feeling were 1.63/1.60 and 1.90/5.76, respectively. The satisfaction score was 3.00 out of 4. CONCLUSION: Allowing the administration of an oral carbohydrate-rich solution in elective surgery patients requiring general anesthesia is safe without serious respiratory complications and effective in providing satisfaction.

Diarreia aguda / Acute diarrhea

Diarreia aguda infecciosa é processo autolimitado. Manejo adequado de um episódio de diarreia aguda, com hidratação, alimentação e uso racional de exames de laboratório e medicamentos, vem preocupando pediatras e órgãos responsáveis pela saúde mundial. São discutidas aqui estas preocupações. Aspectos fisiopatológicos apresentados visam diminuir, ao máximo, a investigação laboratorial e o uso de medicamentos, com tratamento orientado, principalmente para hidratação e alimentação. Orientações da Organização Mundial da Saúde, acompanhadas pelas do Ministério da Saúde, são comparadas com as últimas recomendações, em 2014, das Sociedades Europeias de Gastroenterologia Pediátrica, Hepatologia e Nutrição e de Doenças Infecciosas. Observa-se grande concordância entre elas, principalmente no tratamento baseado, quase exclusivamente, em hidratação e alimentação, enquanto se espera a autolimitação.

Rehidratación oral en deshidratación neonatal severa con hipernatremia crónica / Oral rehydration in severe neonatal dehydration with chronic hypernatremia

La hipernatremia crónica se presenta en neonatos con deshidratación secundaria a baja ingesta de leche materna debida a mala técnica de lactancia, se establece progresivamente y se acompaña de gran pérdida de peso. Requiere corrección lenta para evitar complicaciones neurológicas. La rehidratación oral con soluciones de baja osmolaridad constituye una alternativa de tratamiento segura y eficaz, permite la reposición de volumen, recuperación de peso y corrección de los niveles elevados de natremia en forma gradual.

Chronic hypernatremia occurs in infants with dehydration secondary to low breast milk intake due to poor breastfeeding technique, gradually established and is accompanied by severe weight loss. It requires slow correction to avoid neurological complications. Oral Rehydration Solutions (ORS) of low osmolarity are a safe and effective alternative treatment. ORS of low osmolarity allow volume replacement, weight recovery and gradually correction of the elevated serum sodium levels.

Oral rehydration therapy of ebola virus disease in liberia: A report of 4 cases / 第二军医大学学报

Objective To investigate the effect of oral rehydration salts for treating Ebola virus disease. Methods The treatment outcomes of 4 patients with confirmed Ebola virus disease in Liberia were analyzed. Oral or intravenous rehydration salts were chosen according to the severity of illness and the occurrence of severe vomiting. The fluid volume was determined according to the following conditions; urine, feces and sweat volume, and the daily fluid volume was 750-2 000 mL. Three patients received oral rehydration salts; one patient received oral rehydration salts on the first day and intravenous rehydration salts afterwards due to severe illness. The rehydration salt treatment was given until the complete remission of clinical symptoms. Results The three patients receiving oral rehydration treatment survived and the severe case who also received intravenous treatment died finally. Conclusion Oral rehydration should be used as the first-line choice for early, long-term treatment of patients with mild to moderate Ebola virus disease in West Africa, where the economic and health situation are backward.
