The Impact of Nutrition Drips and Tube Feeds on Critically Ill Patients

The Challenges of Last Resort Feeding Methods

Critically ill patients who are unable to eat by mouth or through a tube to the stomach or gut often rely on nutrition drips as a last resort. However, this method is not the preferred option for feeding due to various reasons. One major concern is the negative impact it can have on a patient's health, including the risk of infection as bacteria can thrive on the drip. Let's explore the challenges and drawbacks of nutrition drips and tube feeds in the ICU.

When someone becomes severely ill, their body may utilize protein from their muscles as a quick source of energy, leading to muscle breakdown. Despite efforts to provide adequate protein in the diet, patients in intensive care for an extended period often experience significant muscle mass loss, making the recovery process more challenging.

Total Parenteral Nutrition (TPN), which involves providing nutrition through an intravenous (IV) line, is a rare practice and is typically reserved for patients who require extensive bed rest as a last resort. However, TPN can potentially lead to cirrhosis and is minimized as much as possible in the ICU. Efforts are made to utilize the gut via a feeding tube whenever feasible.

The Drawbacks of Tube Feeds

Tube feeds, commonly administered to sedated and intubated patients in the ICU, also come with their own set of challenges. One concern is the quality of ingredients used in these feeds, which often include substances like corn syrup that may not provide optimal nutrition.

Prolonged immobility, such as in patients in a coma or on prolonged bed rest, can lead to deconditioning of the body, resulting in muscle loss. This immobility weakens the heart muscles, skeletal muscles, and bones, further exacerbating the patient's condition.

In addition to muscle loss, prolonged immobility can cause a release of protein into the blood and an increase in calcium levels. Patients in a coma or on prolonged bed rest may also experience a range of other issues related to their body's decompensation.

Balancing Nutrition and Weight Concerns

Interestingly, patients on tube feeding are generally not encouraged to lose weight, even if they are obese. This is because being critically ill requires a significant amount of energy, and muscle loss is a concern. Therefore, maintaining adequate nutrition becomes crucial in preventing further muscle deterioration.

Body composition in the ICU is influenced by various factors, including lack of movement, the reason for hospitalization, and the effects of gravity on the heart, muscles, and bones. It is essential to address these factors and provide appropriate nutrition to prevent further complications.

While the nutrition drip remains the best available option for critically ill patients who cannot eat by mouth or through a tube, it is far from ideal. The negative effects it can have on the patient's health, coupled with the risks of infection, highlight the need for alternative feeding methods.


Nutrition drips and tube feeds play a crucial role in providing nutrition and energy to critically ill patients who cannot eat by conventional means. However, these methods come with their own challenges and drawbacks. Efforts are made to minimize the use of TPN and prioritize the gut via feeding tubes whenever possible. The ICU environment and prolonged immobility can significantly impact a patient's body composition and overall health. By addressing these challenges and providing optimal nutrition, healthcare professionals strive to promote better outcomes for critically ill individuals.
