Chest Tube Drainage System
Chest Tube Drainage System samer kareem 3,355 Views • 2 years ago

If you’re like me, you probably hook your chest tube up to a Pleur-Evac, put it on the ground, then back away slowly. Who knows what goes on in that mysterious bubbling white box? Hopefully this will post shed some light. Isn’t this just a container for stuff that comes out of the chest? Why does it look so complicated? It’s complicated because the detection/collection of air and fluid require different setups. Most commercial models also allow you to hook the drainage system to wall suction, so you can quickly evacuate the pleural space. This requires its own setup. Because of the need to juggle air, fluid and suction, the most common commercial system includes 3 distinct chambers. If you were to simplify the device, or build one out of spare bottles and tubes, it might look like this:

Deep Tendon Reflexes Exam
Deep Tendon Reflexes Exam samer kareem 6,843 Views • 2 years ago

In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself.

Liver Abscess Aspiration
Liver Abscess Aspiration samer kareem 2,384 Views • 2 years ago

An untreated hepatic abscess is nearly uniformly fatal as a result of complications that include sepsis, empyema, or peritonitis from rupture into the pleural or peritoneal spaces, and retroperitoneal extension. Treatment should include drainage, either percutaneous or surgical. Antibiotic therapy as a sole treatment modality is not routinely advocated, though it has been successful in a few reported cases. It may be the only alternative in patients too ill to undergo invasive procedures or in those with multiple abscesses not amenable to percutaneous or surgical drainage. In these instances, patients are likely to require many months of antimicrobial therapy with serial imaging and close monitoring for associated complications.

Lumbar Fusion of L5-S1 Surgery
Lumbar Fusion of L5-S1 Surgery samer kareem 3,976 Views • 2 years ago

At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may re­sult when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.

Types of multiple myeloma. Multiple myeloma is the most common type of plasma cell cancer. The bones and bone marrow are the main sites where myeloma cells (abnormal plasma cells) are produced. The myeloma cells can form tumours, called plasmacytomas, in many bones in the body.

Huge Hernia Repair
Huge Hernia Repair samer kareem 5,092 Views • 2 years ago

A giant abdominal wall hernia can develop from an existing ventral or incisional hernia, sometimes arising after one or more failed repair attempts. These hernias may also result from a traumatic injury where the abdomen was required to be left open and healing was delayed. In giant abdominal wall hernias, multiple loops of intestines and sometimes other abdominal organs reside within the hernia sac. The abdominal wall muscles then become conditioned to this and retract reducing the available space inside the abdomen.

Delivering Breech Baby

Most babies will move into delivery position a few weeks prior to birth, with the head moving closer to the birth canal. When this fails to happen, the baby’s buttocks and/or feet will be positioned to be delivered first. This is referred to as “breech presentation.” Breech births occur in approximately 1 out of 25 full-term births.

Natural Childbirth
Natural Childbirth samer kareem 4,458 Views • 2 years ago

A natural, unmedicated approach to labor and birth will suit you best if you want to remain in control of your body as much as possible, be an active participant throughout labor, and have minimal routine interventions such as continuous electronic monitoring. If you choose to go this route, you accept the potential for pain and discomfort as part of giving birth. But with the right preparation and support, women often feel empowered and deeply satisfied by natural childbirth.

How Healthy Heart Works
How Healthy Heart Works samer kareem 9,093 Views • 2 years ago

To understand congenital heart defects, it's helpful to know how a healthy heart works. Your child's heart is a muscle about the size of his or her fist. The heart works like a pump and beats 100,000 times a day. The heart has two sides, separated by an inner wall called the septum. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart receives the oxygen-rich blood from the lungs and pumps it to the body. The heart has four chambers and four valves and is connected to various blood vessels. Veins are blood vessels that carry blood from the body to the heart. Arteries are blood vessels that carry blood away from the heart to the body.

Pneumothorax Easy explanation
Pneumothorax Easy explanation samer kareem 1,837 Views • 2 years ago

A pneumothorax occurs when some of the tiny air sacs (alveoli) in a baby's lung become overinflated and burst. This causes air to leak into the space between the lung and chest wall (pleural space). The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby's lungs lack the slippery substance (surfactant) that helps them stay open. Therefore, the tiny air sacs are not able to expand as easily. If the baby is put on a breathing machine (mechanical ventilator), there is extra pressure on the baby's lungs, which can sometimes burst the air sacs.
