How to measure for an ostomy bag?

by rosa•

Measuring for an ostomy bag is a crucial step in ensuring comfort, functionality, and optimal protection for individuals living with ostomies. As an established ostomy bag supplier, I understand the importance of accurate measurements and the impact they have on the well – being of ostomates. In this blog, I will share comprehensive guidelines on how to measure for an ostomy bag effectively. Ostomy Bag

Understanding the Ostomy and the Bag

Before delving into the measurement process, it’s essential to have a basic understanding of what an ostomy is and how an ostomy bag works. An ostomy is a surgical procedure that creates an opening (stoma) on the abdominal wall to divert the flow of urine or feces from the normal urinary or digestive tract. Ostomy bags, also known as pouching systems, are designed to collect the output from the stoma.

There are different types of ostomy bags, including one – piece and two – piece systems. One – piece systems have the bag and the skin barrier as a single unit, while two – piece systems consist of a separate bag and skin barrier that can be attached and detached. The choice of the system depends on individual preferences, stoma characteristics, and lifestyle.

Preparing for Measurement

Before taking any measurements, it’s important to gather the necessary tools. You will need a measuring guide, which is usually provided by ostomy product manufacturers. These guides come in various shapes and sizes to accommodate different stoma shapes. Additionally, you will need a mirror to help you see the stoma clearly, a pen or marker to mark the measurements, and a clean, dry surface to work on.

It’s also crucial to ensure that the stoma and the surrounding skin are clean and dry. Gently clean the area around the stoma with warm water and a mild, fragrance – free soap, then pat it dry with a soft towel. Avoid using any lotions, creams, or powders on the stoma or the surrounding skin, as these can interfere with the adhesion of the ostomy bag.

Measuring the Stoma

The first step in measuring for an ostomy bag is to measure the stoma. The stoma is the opening on the abdominal wall, and its size and shape can vary depending on the type of ostomy and individual factors.

  1. Determine the Stoma Shape
    • Most stomas are either round, oval, or irregular in shape. To determine the shape of the stoma, use a mirror to get a clear view. If the stoma is round, it will have a uniform circular appearance. An oval stoma will be longer in one direction than the other, and an irregular stoma may have an uneven or non – standard shape.
  2. Measure the Size
    • Round Stomas: For round stomas, place the measuring guide on the stoma and select the circle that best fits the stoma without overlapping or leaving gaps. Mark the size on the measuring guide with a pen or marker.
    • Oval Stomas: When measuring an oval stoma, measure the length and width of the stoma using the oval – shaped holes on the measuring guide. Place the guide on the stoma and find the oval that matches the stoma’s dimensions as closely as possible. Mark both the length and width measurements.
    • Irregular Stomas: Measuring irregular stomas can be a bit more challenging. In this case, you may need to trace the outline of the stoma on the measuring guide. Gently place the guide over the stoma and use a pen to carefully trace the outer edge of the stoma. Make sure the tracing is as accurate as possible.

It’s important to measure the stoma at least once a week, especially during the initial weeks after ostomy surgery, as the stoma may change in size during the healing process.

Considering the Peristomal Skin

The skin around the stoma, known as the peristomal skin, also plays a crucial role in the measurement process. The ostomy bag’s skin barrier should fit snugly against the peristomal skin to prevent leakage and irritation.

  1. Assess Skin Condition
    • Look for any signs of redness, irritation, rashes, or sores on the peristomal skin. If there are any skin issues, it’s important to address them before measuring for a new ostomy bag. Consult a healthcare professional, such as an ostomy nurse, for advice on treating skin problems.
  2. Check for Skin Folds and Contours
    • Take note of any skin folds or contours around the stoma. These can affect the fit of the ostomy bag. If there are significant skin folds, you may need to choose a moldable skin barrier that can be shaped to fit the contours of the skin. Some ostomy bags also come with convex skin barriers, which can help provide a better seal against the skin, especially if the stoma is set deep or there are skin folds.
  3. Measure the Distance from the Stoma to Skin Folds or Other Obstacles
    • If there are skin folds or other obstacles near the stoma, measure the distance from the edge of the stoma to these points. This measurement will help you choose an ostomy bag with a skin barrier that is large enough to cover the stoma and reach the skin folds or other areas to prevent leakage.

Measuring for the Right Ostomy Bag Size

Once you have accurately measured the stoma and considered the peristomal skin, it’s time to choose the right ostomy bag size.

  1. Select the Correct Skin Barrier Size
    • Based on the stoma measurements, choose a skin barrier that has a hole size that matches the stoma size. The hole in the skin barrier should be slightly larger than the stoma (usually about 1/16 – 1/8 inch larger) to prevent irritation.
  2. Consider the Bag Capacity
    • The capacity of the ostomy bag depends on the type of ostomy and the volume of output. For example, individuals with a colostomy may require a bag with a smaller capacity, as the output is more formed. On the other hand, those with an ileostomy or urostomy may need a larger – capacity bag, as the output is more liquid.
    • Most ostomy bags come in different sizes, such as small, medium, and large. Consult with a healthcare professional or refer to the product documentation to determine the appropriate bag capacity for your needs.

Measuring for Special Situations

There are some special situations where additional considerations need to be taken into account during the measurement process.

  1. Stoma Prolapse or Retraction
    • A stoma prolapse occurs when the stoma sticks out further than normal, while a stoma retraction means the stoma is pulled inwards. In these cases, it’s important to measure the stoma at its fullest or deepest point, respectively. You may also need to choose a different type of ostomy bag or skin barrier. For example, a convex skin barrier may be more suitable for a retracted stoma to help create a better seal.
  2. Stomas in Unusual Locations
    • Sometimes, stomas can be located in unusual places on the abdomen, such as near the waistline, in a skin crease, or close to a surgical scar. In these situations, you need to take extra care when measuring to ensure a proper fit. You may need to choose ostomy bags with special features, such as low – profile designs or flexible skin barriers, to accommodate the unique location.

Importance of Accurate Measurement

Accurate measurement for an ostomy bag is not just about getting the right fit. It has a significant impact on the overall quality of life for ostomates.

  1. Preventing Leakage
    • A properly measured ostomy bag will fit snugly around the stoma, preventing leakage of waste material. Leakage can cause skin irritation, odor problems, and discomfort, and can also lead to social embarrassment for the ostomate.
  2. Protecting the Peristomal Skin
    • An ill – fitting ostomy bag can rub against the peristomal skin, causing irritation, redness, and even breakdown. Accurate measurements ensure that the skin barrier fits properly, protecting the peristomal skin from the harmful effects of waste products.
  3. Enhancing Comfort
    • A well – fitting ostomy bag is more comfortable to wear. It allows the ostomate to move freely and engage in daily activities without the worry of the bag shifting or being uncomfortable.
