What Iv Fluids Are Given For Dehydration

There is a lack of high-quality evidence, such as evidence from randomized controlled trials, to guide intravenous fluid management.4 Safe IV fluid prescribing requires integration of appropriate clinical skills, such as fluid balance assessment, with an understanding of fluid physiology under normal conditions. conditions and pathology and characteristics of widespread intravenous fluids.

Iv ‘normal Saline’: A Medical Habit

Water makes up about 60% of total body weight in men and 55% in women (fat content is slightly higher in women). Although water is not distributed evenly throughout the body, it can be thought of as occupying intracellular and extracellular fluid compartments (fig. 1 ⇓ ). Extracellular fluid consists mainly of plasma and interstitial fluid separated by the capillary membrane IV ‘Normal Saline’: Medical Practice : Shots – Health News IV bags are filled with a solution called normal saline to treat problems ranging from vomiting to dizziness. . However, there is less evidence for using saline than for other intravenous options.

On a recent walk through the emergency room where I worked, I saw the number of patients with IV fluid bags over their heads. Almost everyone had one.

Our emergency room in Boston is not unique. IV fluids are one of the most common medical interventions in the world. Several types exist, but one known as normal saline is the most popular. More than 200 million liters are used annually in the United States.

Primarily a treatment for dehydration, normal saline is given without a second thought for conditions ranging from vomiting to rapid heart rate to dizziness.

Iv Therapy: Definition, Types, Complications, & More

For such a treatment, you’d probably expect the brine to be thoroughly researched and purified. Apparently, that never happened. Now there’s a rethinking of whether saltwater is really the best way to go.

Century for the treatment of cholera, which was then known as a disease that killed by dehydration. Early physicians knew that human blood was salty, and a Scottish doctor named Latta developed a primitive saline solution to replace what was lost in the intestines through the veins. The effect was “amazing,” he said

In the 1880s, scientists learned more about the main chemical elements in human blood. A physiologist named Sidney Ringer created a solution that contained sodium, potassium, and chloride in concentrations similar to blood. It is still used today. We call this lactated Ringer’s solution.

Ringer’s solution was slow to catch on, and a simpler salt solution called normal saline became the de facto IV fluid in the early 20th century. Descendant of the original liquid Latta, normal saline contains only two substances – water and salt.

What Is Iv Therapy Used For? Everything You Need To Know About Iv Fluids

The origin of normal saline water was determined in 1883 by a Dutch scientist named Hamburger. His work incorrectly suggested that the concentration of salts in human blood was 0.9 percent. He claimed that a solution of equal concentration would be a “normal” composition for intravenous fluids, hence the name.

Interestingly, the elevation of normal saline as the standard IV fluid was based solely on Hamburger’s early experiments. “How it came into common use as an intravenous fluid remains a mystery,” a group of British doctors wrote in 2008, citing the lack of any other experimental data to support it. “Perhaps this is due to the ease, convenience and cheapness of mixing common salt with water.”

As it turns out, normal saline isn’t very normal at all. The average sodium level in a healthy patient is about 140 (measured in something called milliequivalents per liter). For chloride, it is about 100. But the concentration of sodium and chloride in normal saline solution is 154. This is quite abnormal – especially the chloride.

It wasn’t until the 1980s that researchers began to investigate whether higher chlorine concentrations could have adverse effects. In 1983, a scientist showed that high levels of chloride can reduce blood flow to a dog’s kidneys, causing damage or even kidney failure. And in the 1990s, scientists showed that high levels of chloride in normal saline can acidify the blood, a change that disrupts all kinds of biochemical processes in the body.

The Basics Of Iv Fluids For Emergency Scenarios

Only in the last 10 years have there been serious attempts to find an answer to this question. The first attempt appeared in 2012. Researchers examined a database of patients who received saline or balanced solutions such as lactated Ringer’s during surgery and compared the rates of complications and mortality between the groups. The findings were surprising—those receiving normal saline had a 2.7 percent higher mortality rate and more complications.

That year, Australian doctors showed that ICU patients receiving chloride-rich fluids had almost twice the risk of kidney damage compared to those receiving balanced fluids. A 2013 study found more deaths and longer hospital stays among surgical patients receiving normal saline. The following year, Duke researchers found a 3 percent increase in mortality when sepsis patients were treated with saline rather than balanced fluids.

All of these studies had limitations, and none of them were randomized controlled trials that represent the gold standard for uncovering scientific truth.

Lead author Dr. Matthew Semler. With colleagues at Vanderbilt, Semler studied 15,000 ICU patients who were randomly assigned to receive balanced fluids such as normal saline or lactated Ringer’s and found that those in the latter group fared slightly better.

Dehydration: A Cause For Concern

The researchers measured the overall outcome of death, need for dialysis, or ongoing kidney problems. About 14 percent of patients receiving balanced fluids experienced this outcome, compared to about 15 percent for those receiving saline.

“Given two solutions that are equally available, equally affordable, and bought by millions of adults every year, 1 percent is pretty good,” Semler said. “With an expensive drug, we’d be lucky to improve mortality by 1 percent with a liquid that costs $2.”

He took another step to show the significance of the study’s findings. “Every year in the United States, 5 million patients are admitted to the intensive care unit. “For every 100 patients treated with balanced fluids instead of saline, 1 fewer patients will experience death, new dialysis, or ongoing kidney problems.”

That’s pretty good, especially considering that 125 patients would need to take blood pressure medication for 5 years to prevent one fatal stroke. Or, to prevent a heart attack, more than 1,600 healthy patients need to take aspirin for a year.

Intravenous Fluid Management

“With tens of millions of patients receiving these fluids each year in the United States, switching from normal saline fluids to balanced fluids has the potential to change outcomes for a large number of patients,” he said, “significantly more than most. new patients. blockbuster drugs.”

I tend to share his enthusiasm. I think I’ll reach for the Ringer’s next time I give a patient IV fluids. You are on night shift and your short-term resident is concerned that their 3-year-old patient has pyelonephritis. They continued to vomit despite receiving 4 mg of ondansetron. Bed urine confirms leukocytes, nitrates, blood and ketones. On examination, the child is alert but has dull, red, dry oral mucosa. They have a central RR of 30, SBP of 100, HR of 150 and CRT of 2 seconds. According to your assessment, the child is ill but not in shock, so you ask the resident to start 60 mg/kg benzylpenicillin and 7.5 mg/kg gentamicin and IV fluids.

The resident does not have much pediatric experience and asks for your guidance on how best to approach continuous rehydration.

These conditions require specialist advice and often have their own guidelines or involve a discussion with a pediatrician.

Prescribe isotonic fluids such as 0.9% sodium chloride, Hartmann’s or Plasma-lyte 148 – we usually add 5-10% glucose.

The main difference to note is our serum chloride of 103 mmol/l compared to the 154 mmol/l chloride you get with 0.9% saline.

Reduces renal perfusion and causes acute kidney injury. Research in this area is currently not strong enough to draw a final conclusion. Current evidence suggests that all 3 fluids are acceptable, and in the emergency department we cannot hold patients long enough to administer large amounts of fluid compared to intensive care or pediatrics, so our initial choice of fluid therapy has been this and or not measured relative to the other.
