Barium Enema

 

A Barium Enema is a special type of X-ray examination that allows doctors to examine your lower intestinal tract. After delivering a contrast solution that contains the metallic element barium into your rectum while a technician takes X-ray images of the area. The barium solution will be delivered using an enema — a process in which your doctor pushes a liquid into your rectum through your anus.

Contraindications 
• Pregnancy 
• Allergic reaction 
• Hematoma

Your doctor will ask you to cleanse your bowels the night before your test. This may include using laxatives or taking an enema at home.

You shouldn’t eat anything after midnight the night before your procedure. On the day of the procedure, you can drink clear liquids, such as water, tea, juice, or broth. This is to ensure that your colon is clear of any stool, which could show up in the X-ray images. Tell your doctor if you’ve been having problems with your bowel movements prior to the test.

A barium enema typically takes between 30 and 60 minutes and is performed at a hospital or specialized testing facility. You’ll change into a hospital gown and remove any jewelry or other metal from your body. Metal can interfere with the X-ray process.

You’ll be positioned on an exam table. X-rays will be taken to ensure that your bowels are clear. This may also involve a physical rectal exam.

The radiologist will then insert a small tube into your rectum and introduce the barium and water mixture. The radiologist may gently push air into your colon after the barium has been delivered in order to allow for even more detailed X-ray images. This is called an air-contrast barium enema.

The technician will instruct you to hold still and hold your breath while the X-ray images are taken. You’ll most likely be repositioned several times to take pictures of your colon from different angles. This may cause you some discomfort and cramping, but it’s typically mild.

If you’re having trouble keeping the solution in your colon, alert the technician.

After the procedure, the majority of the barium and water will be removed through the tube. The rest you’ll pass in the bathroom.

Introduction to ECG

MEANING OF ECG An electrocardiogram is a picture of the electrical conduction of the heart. By examining changes from normal on the ECG, clinicians can identify a multitude of cardiac disease processes. There are two ways to learn ECG interpretation — pattern recognition (the most common) and understanding the exact electrical vectors recorded by an ECG as they relate to cardiac electrophysiology — and most people learn a combination of both. This tutorial pairs the approaches, as basing ECG interpretation on pattern recognition alone is often not sufficient. Parts of an ECG The standard ECG has 12 leads. Six of the leads are considered “limb leads” because they are placed on the arms and/or legs of the individual. The other six leads are considered “precordial leads” because they are placed on the torso (precordium). The six limb leads are called lead I, II, III, aVL, aVR and aVF. The letter “a” stands for “augmented,” as these leads are calculated as a combination of leads I, II and

Learning Objectives For The Skull •  List and identify the bones of the brain case and face • Locate the major suture lines of the skull and name the bones associated with each. • Define sinuses and identify the location of each • Identify the bones and structures that form the nasal septum and nasal conchae, and locate of the hyoid bone •  Identifythe bony openings of the skull Anterior View of the Skull  Lateral View of Skull Bones of the Brain Case Parietal Bone Temporal Bone Frontal Bone Occipital Bone Sphenoid Bone Ethmoid Bone Sutures of the Skull Facial Bones of the Skull Maxillary Bone Palatine Bone Zygomatic Bone Nasal Bone Lacrimal Bone Inferior Nasal Conchae Vomer Bone Mandible Paranasal Sinuses Hyoid Bone The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeball

SHOULDER X-RAY

The basic projections are A.P and lateral oblique ➢ Antero posterior (A.P):- The patient laid supine or erect, and slightly rotated to the affected side approximately 15° degrees.  The opposite side should be supported with pad when the supine position is used, the arm should be extended and the hand rotated outwards so that the palm is facing the tube. Centering point: - Center 1inch (2.5cm) inferior to the coracoids process of the scapular. ➢ Lateral oblique: - from the previous position the arm and forearm should be abducted and flexed the elbow joint, with the forearm across the abdomen, and the forearm supported with the other hand. Centering point: - Center to the head of the humerus. Essential image characteristics, The image should demonstrate the bones of the shoulder joint clearly, head of the humerus and the end of acromion and part of the scapula. References: MIT.
