The key difference between monophasic and biphasic defibrillator is that the monophasic defibrillator is a type of defibrillation waveform where a shock is delivered to the heart from one vector as shown below. Whereas, in biphasic defibrillation, shock is delivered to the heart via two vectors.
LIS Closed done at 5 O clock position, using Scalpel blade 15. After feeling the groove between internal and external anal sphincter, the blade is passed in and the lower 1/2 of Internal anal sphincter is cut. Remain below dentate line. If anal mucosa is accidently cut suture with 4-0 rapid vicryl. In event of bleeding, pinchcock for 5 minutes.
Wound healing, or wound repair, is the body's natural process of regenerating dermal and epidermal tissue. When an individual is wounded, a set of complex biochemical events takes place in a closely orchestrated cascade to repair the damage. These events overlap in time and may be artificially categorized into separate steps: the inflammatory, proliferative, and remodeling phases (Some authors consider healing to take place in four or more stages, by splitting different parts of inflammation or proliferation into separate steps.). In the inflammatory phase, bacteria and debris are phagocytized and removed, and factors are released that cause the migration and division of cells involved in the proliferative phase.
When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.

The spleen is an organ in the upper far left part of the abdomen, to the left of the stomach. The spleen varies in size and shape between people, but it’s commonly fist-shaped, purple, and about 4 inches long. Because the spleen is protected by the rib cage, you can’t easily feel it unless it’s abnormally enlarged. The spleen plays multiple supporting roles in the body. It acts as a filter for blood as part of the immune system. Old red blood cells are recycled in the spleen, and platelets and white blood cells are stored there. The spleen also helps fight certain kinds of bacteria that cause pneumonia and meningitis.
Cleft palate is among the most common birth defects affecting children in North America. The incomplete formation of the roof of the mouth can occur individually, or in addition to cleft lip. Cleft palate repair is a type of plastic surgery to correct this abnormal development both to restore function and a more normal appearance. This video explains what to expect for families scheduled for cleft palate surgery at the Craniofacial Anomalies Program at University of Michigan C.S. Mott Children's Hospital.

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.
