ABSTRACT
Background: Proper nutritional support is one of the important caring aspects in patients who were hospitalized in ICU
Objective: This study was done to investigate Oral Drop Gastrolit effect on the gastric residual volume [GRV] in mechanically ventilated patients hospitalized in ICU
Methods: In this clinical trial, 50 mechanically ventilated patients were recruited using convenience sampling method; and were randomly divided into two control [Placebo = water] and experimental groups [Gastrolit]. Intervention group patients were given Gastrolit [20 drops] three times a day for 4 days. GRV was measured before the gavages. The mean GRV of patients were compared in the two groups for 4 days. Data were analyzed using the independent t-test, Chi squared test, and Mann Whitney u test and Friedman test in the SPSS-16
Results: The results showed that most patients were male [60%], and their mean age +/- SD were 63.06+/-19.6. GRV decreased in the intervention group but increased in the control group. The mean GRV in the intervention group on the second, third, and fourth day significantly lower than the control group [P<0.0001]
Conclusion: It seems Gastrolit can decrease GRV in mechanically ventilated patients, so it can be used to improve gastric emptying and prevent delayed gastric emptying complications
ABSTRACT
The kinds of pollutants such as heavy metals, especially, can be removed from water and waste water by biological materials via biosorption.These heavy metals can be also recovered by adsorbents. The mentioned methods have more importance due to the advantages such as cheapness. In this study marine red alga Gerasilaria sp. was used as an aquatic fern to remove Ni2+in the flow operation. A glass column with an internal diameter of 2 Cm and 35 Cm in length were investigated as a packed column. The adsorption process with influencing factors such as initial concentrations, pH, retention time [15, 30 and 45 min], and adsorbent dosage [2.5 and 3.5 g] in temperature home were considered. Synthetic solution of Ni [II] in distilled water was prepared using NiCl[2].6H[2]O [97%] with initial concentrations 25, 40, 70 mg/L. The maximum uptake at pH=5 were obtained 83.01%, 80.69% and78.23% respectively. An atomic absorption spectrometer [GBC-932] was used for analyses of the artificial waste after exposure to alga. It was shown that the non-living Gerasilaria sp. adsorb according to Langmuier physical low and the kinetic studies was appeared that all of the used non-living alga samples adsorbed according to a second order model of kinetic
