Filter by:The purpose of the study is to determine whether participants who are dictating their own administration of IV fluid boluses in response to thirst, receive better protection from hypovolaemia and volume overload than those who undergo routine fluid management. Thirst is prominent in critically ill patients and is related to dehydration. In a recent study of the symptoms experience in ITU patients at high risk of dying, the sensation of thirst was reported in 70.8% of assessments made and was considered to be one of the most intense stressors. Thirst and dehydration can be combated in an ITU setting by consuming oral fluids and through administration of intravenous fluids. However, in older adults, frailty and dysphagia reduces patients' capability to access fluid and results in thirst. In addition, the administration of IV fluids is determined by the attending physician and is often only re-evaluated on a daily or twice-daily basis. The Quench machine has been designed to allow the patient to have more control over their oral and IV fluid administration protocol. This may help reduce the sensation of thirst and dehydration in patients. The machinery is an automated fluid delivery system that will administer a given bolus of IV fluid in response to a trigger provided by the patient. The purpose of the current study is to examine the physiological basis for the functional benefit of this Quench system by investigating the effectiveness of the thirst response in healthy humans as a guide for administration of intravenous fluid boluses. To explore this, the investigators have designed a randomised, cross-over study. On one visit IV fluid boluses will be administered as per the participants' request in response to thirst. In the second arm of the study participants will be administered routine IV fluid maintenance as per NICE guidelines. Body mass at the end of a 4 hour fluid administration intervention will be our primary research outcome and will be compared between the two arms of the study. From this comparison the investigators hope to show that a patient would be able to accurately manage their level of hydration, both in terms of correcting dehydration and avoiding fluid overload. It is thought that avoiding states of fluid imbalance can reduce post surgical recovery times, reduce the incidence of post operative complications and avoid critical complications of fluid imbalance, such as acute kidney injury.
The purpose of the study is to determine serum inflammatory adhesion molecules levels in hyperemesis gravidarum
The investigators previously found that a blood urea nitrogen/creatinine (BUN/Cr) ratio >15 is an independent predictor of early deterioration after acute ischemic stroke. Another study was conducted to determine whether urine specific gravity, another indicator of hydration status and one more easily obtained, is also an independent predictor of early deterioration or stroke-in-evolution (SIE) in such patients. The investigators also conducted a preliminary study, enrolling ischemic stroke patients with a BUN/Cr ratio >15 and find daily Bun/Cr based hydration help to decrease post stroke infection rate and improve 3 months functional outcome. In this study, daily urine specific gravity will be used to adjust hydration therapy in ischemic stroke patients with initial Bun/Cr ratio <15. The primary outcome is the post stroke infection rate in the first 7 days after admission, and secondary outcome is 3 months functional outcome using mRS.
Aims: - evaluate the hydric status through bioimpedance spectroscopy in consecutive acute myocardial infarction patients referred for primary PCI; - assessment of renal artery stenosis incidence through renal angiography in consecutive STEMI patients; - fully characterize the complex hydration, metabolic and endothelial profile of these patients in the attempt to define the role played by dehydration in the complex dynamics of acute myocardial infarction.
The assessment of clinical dehydration scales diagnostic accuracy (CDS scale, WHO scale, Gorelick scale) among small children.
- There is no definite tool for measurement of dehydration in children - Subjective clinical dehydration scale is considered as valuable scoring system, but it cannot be reliable among clinicians sometimes. - Some authors found Inferior vena cava/Aorta ratio can be a objective marker for dehydration - However, there is no evidence of correlation between clinical dehydration scale and inferior vena cava/aorta ratio - We will observe correlation between clinical dehydration scale and inferior vena cava/aorta ratio and change of the ratio according to hydration with intravenous normal saline infusion.
Dehydration and refusal to eat and drink are common complaints in the Pediatric ED (Emergency Department). Most of these children have had an unsuccessful trial of oral rehydration in their community service, therefore are treated with IV rehydration. There is no consensus as to which IV solution is the best one for rehydration. Children who are unwilling or unable to eat and drink produce Keto bodies. Theoretically, addition of glucose to the IV solution would prevent catabolic metabolism and reduce the keto bodies blood concentration which should lead to a faster objective and subjective improvement of the child's condition. The proposed study is a double blind randomized clinical trial. Children will receive either NaCl 0.9% or NaCl 0.9% + 5% glucose randomly in numbered bags. The type of solution will be known to the pharmacy only. Study aims: - Primary aim: to compare the number of hospitalizations among dehydrated pediatric patients treated with either one of the IV fluids mentioned above. - Secondary aim: To evaluate for the possibility of hypoglycemia secondary to hyperinsulinism as a response to a rapid administration of glucose. Study population: The study will include 700 children 6 month to 18 years of age. It will be conducted over 18 months in the Pediatric ED of Carmel Medical Center. Currently, data regarding the use of dextrose containing solutions is lacking. As dehydration is one of the most common medical problems encountered by the physician in the pediatric ED, it is of outmost importance to evaluate the optimal IV solution used in this setting.
Serotonin excretion was investigated in the nausea and vomiting associated with hiperemezis gravid arum.
The purpose of this study is to examine the body-fluid balance in patients with retinal vascular occlusion and the influence of drinking habits and hemodilution on the degree of body hydration.
The purpose of this study is to assess palliative care physicians' attitudes, beliefs and practice patterns related to parenteral hydration at the end of life in Latin America and Spain. Objectives: 1. To assess palliative care physicians' attitudes, beliefs and practice patterns related to parenteral hydration at the end of life in Latin America and Spain. 2. To assess cross-national differences in practice patterns related to parenteral hydration at the end of life. (Latin America vs. Spain). 3. To determine the percentage of physicians who practice parenteral hydration at the end-of-life in the hospital setting and the home setting. 4. To examine the association between providers' parenteral hydration practice patterns and: - 1. provider demographic characteristics; - 2. specific characteristics of their practice settings; and - 3. training and experience in end of life care; 5. To determine which factors most predict the practice of parenteral hydration at the end of life among palliative care physicians.
