Which factor can contribute to buried bumper syndrome due to mechanical pressure?

• A. Poor hygiene
• B. Malnutrition
• C. Excessive tightening of the external bolster
• D. Age over 75

Answer: (C)

Buried bumper syndrome occurs when the external bolster presses too tightly against the abdominal wall, squeezing the internal bumper into the stomach wall and cutting off blood flow. This mechanical pressure leads to ischemia and erosion, causing the internal bumper to become embedded. Excessive tightening of the external bolster directly creates that sustained compression, making it the most relevant factor for this complication. Factors like hygiene or nutritional status affect infection risk or tissue healing but do not cause the specific compressive injury, and age alone isn’t a direct mechanical contributor. To prevent this, keep the external bolster snug but not tight, allow some movement of the tube, and assess promptly if there’s pain, swelling, drainage, or difficulty infusing.
