Leaking: Leakage of urine may occur from the stoma, particularly if the channel becomes stretched and the valve preventing such leaks fails to self- seal. [5] Bladder spasms, painful contractions of the bladder, can cause leakage from the stoma or the urethra [ 30 ] and may need to be treated with medication called an antispasmodic.
Chest tube clogging can lead to retained blood around the heart and lungs that can contribute to complications and increase mortality. [11] A common complication after thoracic surgery that arises within 30–50% of patients are air leaks. If a chest tube clogs when there is an air leak the patient will develop a pneumothorax.
One of the most common settings for cardiac tamponade is in the first 7 days after heart surgery. [16] After heart surgery, chest tubes are placed to drain blood. These chest tubes, however, are prone to clot formation. When a chest tube becomes occluded or clogged, the blood that should be drained can accumulate around the heart, leading to ...
Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest. An abrupt stop of pulmonary gas exchange lasting for more than five minutes may permanently damage vital organs, especially the brain.
An ostomy pouching system [1] is a prosthetic medical device that provides a means for the collection of waste from a surgically diverted biological system (colon, ileum, bladder) and the creation of a stoma. Pouching systems are most commonly associated with colostomies, ileostomies, and urostomies. [2]
The particles should be greater than 80 μm in diameter in order to prevent migration away from the injection site. On the other hand, materials with particles small enough to be used in small caliber needles may be desirable, in order to leave a smaller needle track, which may reduce the chance of leakage of the material via the needle track.
