2 The Role of CT Scanning for Emergent Trauma Care Rich Lehrer, RT, CRT, BS Ed

3 The Old Days... Plain films - skull, chest, ribs, abdomen, pelvis and additional studies like IVP and/or angiography for suspicious findings. Then came CT - 6 minutes per slice!

8 What’s the Big Deal? Now we can acquire a scan of head/chest/abdomen/pelvis in minutes. Shorter time frame than plain films. Considerably more information making CT scan a good initial survey of injuries and condition.

9 Helical CT - The Need for Speed Continuous & Simultaneous Source Rotation Patient Translation Data Acquisition

11 Helical CT Reconstruction Reconstruct raw data into new images Display anatomy from different planes

12 Rich’s Rules of Trauma Radiography Assume that there is an injury. –Spinal precautions –Internal bleeding IAI –Closed Head Injury CHI

15 The Neurosurgery A-B-C’s Airway Breathing CT Head Scan...

16 Indications for CT Head Major cranial trauma Altered level of consciousness Abnormal neurologic exam Display deterioration under observation Headache - N/V

17 Rich’s Rules of Trauma Radiography Assume that there is an injury. Be aware of your patient’s condition and changes in their condition.

40 Rich’s Rules of Trauma Radiography Assume that there is an injury. Be aware of your patient’s condition and changes in their condition. Know your patient before you meet them. –Current lab values? –History of allergies, heart disease, kidney disease, diabetes, asthma. –Speaks English or is translator necessary? – IV already established?

41 BUN Range mg/dl Blood urea nitrogen (BUN): waste product of metabolism - level indicates if kidney is excreting sufficiently. BUN can rise with dehydration, injury, exercise, or even body size.

42 Creatinine mg/dl Normal metabolic product of creatine & phosphocreatine which are constituents of skeletal muscle. The level of creatinine correlates with overall kidney function. The higher the level, the more abnormal the kidney function.

56 Rich’s Rules of Trauma Radiography Assume that there is an injury. Be aware of your patient’s condition and changes in their condition. Know your patient before you meet them. Be Prepared. –Contrast drawn up –Crash cart or first responder kit available –Suction available

57 CT vs. DPL Stable, conscious => observe Stable or unstable, unconscious => DPL Unstable, conscious, abdomen equivocal => CT or DPL Unstable, definite abdomen signs => Laparotomy

58 CT vs. DPL DPL -ve, patient stable => observe DPL -ve, patient unstable => look elsewhere ie; CT retroperitoneum DPL +ve, patient stable => no Laparotomy, CT to see what we're sitting on DPL +ve, patient unstable => Laparotomy.
