Abstract In order to monitor and optimize therapy, pharmacists must be able to manage children's fluids and electrolytes effectively. The three main components of pediatric fluid treatment are replacement, deficiency, and maintenance. The conventional technique for determining the amount of maintenance fluid needed is still the HollidaySegar equation. Fluid deficiencies must be taken into consideration when calculating the infusion rate for dehydrated patients; these deficiencies are often made up during the first 24 hours of admission. According to current research, hospitalized children may need more sodium than previously thought, therefore electrolyte management is equally crucial, with particular attention to sodium levels. Drug therapy can also be greatly impacted by fluid therapy. Drug distribution and metabolism are impacted by a child's level of hydration, and typical dosages of medications can be harmful to dehydrated individuals, especially when those medications have a high volume of distribution. Pediatric pharmacists have a vital role in monitoring fluid and electrolyte therapy. The most recent findings and developments in this field are highlighted in this paper, along with real-world healthcare applications. The safety and accuracy of fluid distribution for pediatric patients have been greatly improved by technological developments such automated infusion pumps. By adjusting infusion rates according to each patient's unique fluid and electrolyte needs, these smart devices can lower the risk of dehydration or overhydration and facilitate flexible clinical decisionmaking. Additionally, it offers an optimistic outlook on the advancement of wearable sensor technology for babies, which could transform real-time electrolyte and hydration monitoringinpediatriccare.

A crucial component of clinical practice in pediatriccare,especiallyforbabies,isfluidandelectrolyte control, which has a direct impact on patient outcomes. Young children's hydration and electrolyte requirements
are more dynamic and sensitive than those of adults, making the delicate balance of fluids and electrolytes in the body extremely important. Maintaining appropriate hydration, addressing any deficiencies, and replenishing lost fluids are all components of effective fluid treatment for kids. Traditional techniques for keeping an eye on and modifying fluid and electrolyte therapy, however, can be time-consuming and prone to human error. Healthcare practitionerscannowcreateautomated,real-timesystems that continuously monitor these vital indicators thanks to developmentsinInternetofThings(IoT)technologies.[1]. Thissystemconsists ofa wearablegadgetthattracksvital electrolytes, such as sodium, potassium, and chloride, as well as hydration levels using sensors. Real-time transmission of these measurements to medical professionals enables prompt actions in the event that abnormalitiesareidentified.Inadditiontoimprovingfluid and electrolyte management's accuracy and safety, this IoT-based strategy lowers the possibility of problems like drug toxicity that may result from incorrect fluid distribution. Therapy is further optimized by the incorporation of smart infusion pumps, which can modify the fluid infusion rate in response to real-time data from the wearable device. By facilitating more precise, individualized,anddynamicfluidmanagement,thisdevice has the potential to completely transform pediatric treatment and enhance patient safety and clinical results. [2]. Patients in hospitals are supplied electrolytes in a variety of methods. Saline serves a number of vital purposes, including treating dehydration and enhancing overall health. When a saline is administered to a patient inmodern medical treatments,thepatientiscontinuously monitored by a nurse or other caregiver. One of the most crucial duties for a nurse or other caregiver is to keep an eye on the amount of saline in a bottle that is fastened to the patient's body. Nowadays, a large number of women are employed in industrialized countries, which has an impact on how many families care for their infants. Because of the high expense of living, both parents must work. They still have to care for their infants, though, which adds to their workload and stress levels, particularly for the mother. It is not always possible for working parents to care for their children. While they work,theyeitherhireababysitterorsendtheirchildrento

their parents. Some parents are concerned about their children's safety when they are in the care of others.[3]. Anand et.al proposed Saline serves a number of vital purposes, including treating dehydration and enhancing overall health. When a saline is administered to a patient inmodern medical treatments,thepatientiscontinuously monitored by a nurse or other caregiver. One of the most crucial duties for a nurse or other caregiver is to keep an eye on the amount of saline in a bottle that is fastened to the patient's body. The bottle may get empty in situations involving negligence or ignorance, and blood from the patient'sbodymaybegintoflowbackwardintothebottle. There must be a better way to handle this dangerous scenario. We are creating an Internet of Things (IoT)based bottle level monitoring system that will always detect the saline bottle level by alerting the hospital's monitoring room when the bottle content falls below a certain threshold. The suggested device can monitor any fluid and is not electrolyte specific. The solution has the extra benefit of flexibility and modularity since it can be integrated with already-existing bottle stands. [4]. Ahlam Shakeel Ansari et.al H 2 O 2 reacts during operation to chemicallydegradetheelectrolytemembranesinpolymer electrolytefuelcells(PEFCs).Additionally,thecyclicstress broughtonbybeginningandstoppingoperationsdamages the electrolyte membranes. Because water elongates the electrolyte membranes during PEFC operation, and because the membranes contract under waterless conditions during halt operation. The quality of the membranes eventually deteriorates due to the accumulation of these mechanical and/or chemical damages. A perforating testing device was created specifically for this investigation in order to examine the distribution of deterioration on the electrolyte membranes. This testing device allows us to create a "degradation map" that shows the extent of deterioration in a PEFC cell.[5],[6]., System architecture is illustrated in Fig. 1.

The suggested system prototype is built and tested to demonstrate its costeffectiveness and ease of use, as well as to guarantee safe operation,allowingbaby-parentingtotakeplaceanywhere and at any time over the network. Lastly, the prototype shows that the baby monitoring system is successful in keepinganeyeontheinfant'sconditionandsurroundings. [9]. Aleksey.et.al proposed. A dangerous kind of arrhythmia, elevatedblood pressure,andrenal failurecan all result from abnormal electrolyte levels in the blood. A non-invasivemethodofmeasuringheartelectricalactivity, the electrocardiogram (ECG) can pick up on minute variations in electrolyte levels. Although it has been documented that ECGs with aberrant electrolyte ranges, like potassium levels, can be classified, continuous ECGs mustbeused toregress electrolytevalues. Onesignificant obstacle to training machine learning-based models for this purpose is label scarcity.

staff in case of abnormalities. The core of the system is built around the ESP8266 NodeMCU v1.0 microcontroller, whichoffersin-builtWi-Fifunctionality,enablingseamless connectivity to the internet and cloud databases. The system architecture includes a fluid or electrolyte level sensor,whichcontinuouslymeasurestheconcentrationor volume of electrolytes present. This sensor is interfaced with the NodeMCU through analog or digital input pins, dependingonthesensorspecifications.Thesensordatais read at regular intervals (e.g., every 5 seconds), digitized, andcomparedwithapredefined thresholdvalue,which is initiallysetto25%asaminimumsafetymargin.However, thesystemprovidesflexibilityforhealthcareprofessionals to adjust the threshold limit as per medical guidelines or thespecificneedsoftheinfant.
Once the data is received by the microcontroller, the onboard logic evaluates the fluid level using a conditional threshold comparison algorithm. If the sensed valuedropsbelowthethreshold,thesystemidentifiesthis as an abnormal condition. In such cases, a local alert mechanism is triggered via a buzzer or LED indicator to immediately notify anyone in the vicinity. Simultaneously, the system establishes a Wi-Fi connection using the ESP8266's integrated module to send the data to a cloud database such as Firebase, Thing speak, or Blynk. This database stores the fluid level data in real time, enabling both live monitoring and historical trend analysis. The cloud platform also facilitates remote accessibility, where authorizeduserscanaccessdatafrommobileapplications or web dashboards. These interfaces are designed to be user-friendly and provide visualization of electrolyte levels,configurationof thresholdvalues,andaccesstothe alertlog.
The system is equipped with an emergency alert mechanism that is activated when electrolyte levels fall critically low. When this condition is met, the cloud platform sends out instant notifications via SMS, email, or app alerts to registered caregivers, ensuring rapid response to potential medical emergencies. Additionally, the alert messages are timestamped and contain patientspecificidentifiers,makingitsuitableforhospitalorhomecare integration. The entire system was thoroughly tested undersimulatedconditionsusingapotentiometerinplace of the sensor to simulate various electrolyte levels.

To detect sodium ions, there are electrodes called sodiumselective electrodes (Na⁺-ISE).
