What is Trauma?

What is Trauma?Trauma is a serious injury or shock to the body. It is caused by a physical force such as violence or an accident. The injury may be complicated by psychiatric, behavioral, and social factors.

It is critical to have an entire team immediately available to provide care to an injured patient 24-hours a day. This teamwork starts at the scene of the injury where a coordinated, statewide pre-hospital medical system rapidly transports the injured patient from the scene to the hospital providing the appropriate level of care according to criteria established in the statewide trauma regulations. Once at the hospital, a complete team of surgeons, emergency physicians and nurses continue the life-saving treatment.

This team approach to care of the injured patient has had a dramatic impact on saving lives.

Minimally Invasive Procedures for Massive Bleeding

Injuries take many forms. The most advanced hospitals can treat injuries with a variety of approaches that involve well-known ones, like surgery, and newer ones where minimally invasive procedures can replace some surgeries.

As a Level 1 Trauma Center, Hartford Hospital has Interventional Radiologists as part of the Trauma Team. They perform procedures such as "embolization" which is a recognized interventional radiology technique that is used to treat trauma patients with massive bleeding.

Definition

CT colonography is a radiology test that looks at your large intestines, also called your colon. It is one of many options for colon cancer screenings.

Reasons for Test

This test is used to look for polyps or cancers of the colon.

Possible Complications

CT colonography is safe. It can be used if you are too sick to have other forms of colon cancer screening.

In some cases, a contrast material is used. One complication may be an allergic reaction to the contrast.

What to Expect

  • Do not eat for 8-12 hours prior to the test.
  • A bowel cleansing will be done with a laxative. The goal of the cleansing is to rid your colon of all stool. The laxative will cause you to have many bowel movements over several hours.
  • If you have diabetes, talk to your doctor about adjusting your medicines.

A radiologist will position you on your back on a movable x-ray table. Just before the test, a small tube will be inserted into your rectum. Air will be gently pumped through this tube. The table will move slowly though the donut-shaped CT scanner. While this is happening, you will need to lie very still. You will be asked to hold your breath during the scan. The scanning test will then be repeated with you lying on your stomach.

You will be able to leave after the test is done. You can resume your normal diet and activities.

30-40 minutes

You may feel cramping and bloating. You may feel the urge to have a bowel movement.

An expert will review the images. If something abnormal is seen, your doctor may suggest a colonoscopy.

Call Your Doctor

If you were given contrast, call your doctor if you notice:

  • Nausea
  • Itching
  • Difficulty breathing

In case of an emergency, call for medical help right away.
