A brain surgery called a craniectomy is performed to remove a part of your skull in order to relieve pressure in an area when your brain swells from a traumatic brain injury. It is also performed to treat medical conditions that cause your brain to swell or bleed that can be caused by an aneurysm, brain tumor or other cancer.
This 3d animation shows how the surgical procedure decreases intracranial pressure (ICP), intracranial hypertension (ICHT), or heavy bleeding (also called hemorrhaging) inside your skull. If left untreated, pressure or bleeding can compress your brain and push it down onto the brain stem. This can be fatal or cause permanent brain damage.
Brain surgery is a very serious procedure under any circumstances, but a craniectomy is done when there is an immediate risk to the brain and neurological function due to severe brain injury or stroke.

The Epley Maneuver for Vertigo can be very effective at relieving vertigo symptoms, but it’s a procedure that should be performed by a physical therapist or other health care professional. This video is for demonstration purposes only. See Doctor Jo’s blog post about the Epley
Kendall Lee, M.D., describes deep brain stimulation surgery, and how it is is typically done with patients who remain awake, so neurological functions can be measured and maintained. For more information on deep brain stimulation, visit http://mayocl.in/2A09T80.
There are twelve cranial nerves in total. The olfactory nerve (CN I) and optic nerve (CN II) originate from the cerebrum. Cranial nerves III – XII arise from the brain stem (Figure 1). They can arise from a specific part of the brain stem (midbrain, pons or medulla), or from a junction between two parts: Midbrain – the trochlear nerve (IV) comes from the posterior side of the midbrain. It has the longest intracranial length of all the cranial nerves. Midbrain-pontine junction – oculomotor (III). Pons – trigeminal (V). Pontine-medulla junction – abducens, facial, vestibulocochlear (VI-VIII). Medulla Oblongata – posterior to the olive: glossopharyngeal, vagus, accessory (IX-XI). Anterior to the olive: hypoglossal (XII). The cranial nerves are numbered by their loca
Hiatal hernias occur when contents of the abdominal cavity protrude through the esophageal hiatus of the diaphragm. Factors that contribute to the development of a hiatal hernia include an enlargement of the esophageal hiatus due to developmental defects, an increased abdominal thoracic pressure gradient, and the depletion of elastic fibers in the phrenoesophageal membrane with aging. There are four different types of hiatal hernias and management varies depending on the type. Type I, also known as a sliding hernia, is a simple displacement of the gastroesophageal junction into the thoracic cavity. The stomach remains in the abdominal cavity. This is the most common type of hiatal hernia, accounting for about 95% of all hiatal hernias. Types II-IV are classified as paraesophageal hernias. Type II occurs when the gastroesophageal junction maintains its position but the gastric fundus herniates through the diaphragmatic hiatus. Type III has both the gastroesophageal junction and the stomach herniate above the diaphragm. When more than 30% of the stomach is herniated into the thoracic cavity, it is termed a “giant” paraesophageal hernia. A patient has a type IV hernia when other organs, such as the colon, in addition to the stomach herniate above the diaphragm.
A spontaneous vaginal delivery (SVD) occurs when a pregnant woman goes into labor with or without use of drugs or techniques to induce labor, and delivers her baby in the normal manner, without forceps, vacuum extraction, or a cesarean section. Assisted vaginal delivery (AVD) occurs when a pregnant woman goes into labor with or without the use of drugs or techniques to induce labor, and requires the use of special instruments such as forceps or a vacuum extractor to deliver her baby vaginally.

This video illustrates an IM injection for deltoid muscle.
Note that vaccines and other medications can be administered through the deltoid muscle. I will give you some tips through this video.
It is important to check your client’s details such as their medication, time, dose, and the route to be used. Different research works are subject to change the protocols for insertion thus, it is necessary to be up to date with the current changes.
Assemble all the supplies and conduct hand sanitation. Usually, I wear gloves before giving any injection in as much as the CDC may state it is optional unless the patient has an open lesion and contact of body fluids is likely to happen.
Use the acromion process landmark to locate the deltoid muscle. Move your fingers about two widths below the landmark. The patient’s adipose tissue determines the choice of needle length. Note that the needle gauge is determined by the type of medication you plan to give to the patient.
The Z-track technique is recommended rather than pinching the patient’s skin. Pull the patient’s skin to the side using one hand. Use a 90 degree angle to insert the needle to the patient’s skin. At the rate of 10 seconds per mL gently depress the plunger.
Remove the needle carefully and engage the safety precautions then dispose of the needle appropriately in the sharps container. Gauzing helps to cover the injection site.
