Background:The safety of giving intravenous (IV) maintenance fluids according to Holliday and Segar's recommendations of 1957 has recently been questioned after reports of complications caused by iatrogenic hyponatremia in children receiving hypotonic fluids. However, the current practice of choice of maintenance IV fluids for hospitalized children varies worldwide. This study was planned to compare 0.45% and 0.9% saline in 5% dextrose at standard maintenance rates in hospitalized children aged 3 months to 12 years.Objective: Primary objective was to study change in serum sodium level at 24 hours in children receiving total IV fluid maintenance therapy as 0.45% or 0.9% normal saline in 5% dextrose. Secondary objectives of this study were to estimate change in serum sodium levels from the baseline to 48 or 72 hours, if IV fluids were continued, and to find incidence of hyponatremia and hypernatremia after administering these 2 types of maintenance fluids.Methods: This study was an open-label, randomized control trial conducted at the Department of Pediatrics of a tertiary care hospital from July 22, 2019, to October 28, 2019. Two hundred children aged 3 months to 12 years admitted in pediatric emergency and requiring IV maintenance fluid were randomized into 2 groups (group A received 0.45% saline in 5% dextrose, group B received 0.9% normal saline in 5% dextrose) with 100 in each group.Results: Both groups were comparable for baseline characteristics. Fall in mean serum sodium from baseline was more with increasing duration of IV fluids until 24 hours in 0.45% saline group as compared with 0.9% saline group, which was statistically significant ( P < 0.001). The incidence of mild and moderate hyponatremia was significantly more in hypotonic group at 12 hours ( P < 0.001) and 24 hours ( P < 0.001). However, there was no significant difference at 48 hours. Conclusions:The fall in serum sodium values was significant, and there was significant risk of hyponatremia with the use of hypotonic fluids at 12 and 24 hours. Hence, the use of isotonic fluids seems to be more appropriate among the hospitalized children.Trial Registration: CTRI/2019/10/021791.
Introduction: Central venous catheter (CVC) related blood stream infections are associated with serious infectious complications resulting in significant morbidity, increased duration of hospitalization and added medical cost. Aim: The study was done to determine the incidence of central venous catheter related infections, their antimicrobial sensitivity pattern, biofilm production and associated risk factors in hospitalized patients. Material and Method: Catheter tip culture & blood cultures of 143 patients with indwelling central venous catheters were processed. Result: Out of 143 specimens, catheter tip colonization was observed in 45 samples, while 14 were both catheter tip as well as blood culture positive hence included ascatheter related blood stream infections (CRBSI). CRBSI was found significantly associated with increased duration of catheterization, increased number of attempts and placement of CVC in internal jugular vein. Most common isolated organisms were Klebsiella pneumoniae followed by Coagulase negative Staphylococcus, Staphylococcus aureus and Pseudomonas aerguinosa in CRBSI as well as in CVC colonization. Majority of them were resistant to Gentamicin, Ciprofloxacin, Ceftiazidime and Ceftrixone. Biofilm production was determined by tissue culture plate method and was found to be maximum seen in Klebsiella spp. Conclusion: Incidence of CRBSI was 9.79% and of CVC colonization was 34.26%. Rate of CRBSI was 8.53 per 1000 CVC days. Klebsiella pneumoniae was most common isolate and predominant biofilm producer and was found to be multidrug resistant to Gentamicin, Ciprofloxacin, Ceftiazidime.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
