comparison of low osmolar ors and resomal for treating acute watery diarrhea in severely malnourished children aged 6 months to 5 years

Conditions: Acute Watery Diarrhea; Severe Acute Malnutrition in Childhood; Dehydration in Children

Summary: acute watery diarrhea is a common and serious health issue in children, especially in those who are severely malnourished. these children are at a much higher risk of complications such as dehydration, electrolyte imbalances, and even death. oral rehydration solutions (ors) are a widely used treatment to prevent and correct dehydration in such children. however, there are different types of ors, and it is still unclear which one is more effective and safer for use in severely malnourished children. this clinical study is being conducted at the children's hospital, lahore, to compare two different types of ors: low osmolar ors and resomal (a special rehydration solution designed for malnourished children). the aim is to determine which solution is more effective in correcting low potassium levels (a common problem in these children) and to identify which one has fewer side effects, particularly problems like low or high sodium levels that can be dangerous. a total of 72 children between 6 months and 5 years of age, all diagnosed with severe malnutrition and mild to moderate dehydration due to acute watery diarrhea, will be included in the study. they will be randomly assigned to receive either low osmolar ors or resomal. blood tests will be done before and after the treatment to check for changes in electrolyte levels. the frequency of diarrhea and the child's overall response to treatment will also be recorded. the hypothesis of this study is that there is a significant difference in both effectiveness and side effects between the two ors solutions. the results of this study will help doctors choose the safest and most effective ors for treating diarrhea in severely malnourished children, improving care and potentially saving lives.

after approval from ethical review committee of the hospital, 72 (36 in each group) severe malnourished children with watery diarrhea who present in the department of pediatrics medicine university of child health sciences,the children's hospital lahore will be included. parents of the children who fulfill the above criteria will be counseled and explained the details of the study. written informed consent and detailed history will be taken from each patient parent related to duration and frequency diarrhea. they will be divided into the following two groups using lottery method. group-i: low osmolar ors. (mmol/l: na+ 75, k+ 20, cl- 65, citrate 10, glucose 75, and osmolarity 245) group-ii: resomal ors. (na 45 mmol/l, k 40 mmol/l, cl 76 mmol/l, citrate 7 mmol/l, mg 6 mmol/l, zn 300 lmol/ l, cu 45 lmol/l, glucose 125 mmol/l, osmolarity 300 mmol/l) at arrival in the hospital the dehydration status of the children will be assessed using the dehydration severity score (appendix). the weight of each child along with the height will be noted and i/v lines saved under aseptic measure. base line investigations including the electrolytes and renal function tests will be sent to the lab and appropriate management of the infection with suitable antibiotics will be started. fluid deficit will be corrected with 10 ml/kg/h of the assigned ors given over the first 2 hours, then 5 ml/kg/h over a period of 10 to 12 hours until the deficit is corrected. ongoing stool losses will be corrected with 5ml/kg after each watery or loose stool. the patients in group-i will receive low osmolar ors fluid while the patients in group-ii will receive standard ors fluid. 24 hours after the fluid therapy started, blood will be drawn and will be sent for the measurement of electrolytes. the efficacy and side effects will be labelled as per operational definition. the frequency of passage of stool in the 24 hours will also be noted. all data along will the lab values will be recorded into the attached performa, and all the labs will be done from the hospital lab.

Eligibility criteria:
inclusion criteria: * children aged 6 months to 5 years. * both male and female. * children presenting with acute watery diarrhea. * children have mild to moderate dehydration. * children have serum sodium (135-145 meq/l) and serum potassium (2.5-3.4 meq/l). * presence of severe malnutrition, defined as weight-for-length ≤ 3 standard deviations from the median of the world health organization (who) growth standards or mid-upper arm circumference (muac) \<115 mm. * children tolerating oral fluid. * parent or guardian willing and able to provide informed consent for participation. exclusion criteria: * critically ill children with shock, history of not passed urine for 6 h, convulsions and electrolyte abnormality requiring intravenous (iv) for severe dehydration. * history of chronic gastrointestinal disorders, such as inflammatory bowel disease or celiac disease. * received antibiotics within 48 hours before enrollment. * children having any systemic illness requiring hospitalization or specific treatment, such as sepsis or pneumonia.
