What form of ionizing radiation can penetrate deeply?
What form of ionizing radiation can penetrate deeply?
Ionizing radiation is relatively high in energy, and when it collides with an atom, it can completely remove an electron to form a positively charged ion that can damage biological tissues. Alpha particles do not penetrate very far into matter, whereas γ rays penetrate more deeply.
What agent blocks enzymes resulting in a cholinergic crisis?
Organophosphates and Carbamates Organophosphates (OPs) are a major class of insecticides. Their acute toxicity is due to inhibition of the enzyme acetylcholinesterase (AChE) resulting in the accumulation of acetylcholine in the synapse, with an ensuing cholinergic crisis.
What is the difference between myasthenic crisis and cholinergic crisis?
Cholinergic crisis is when there is no improvement or worsening of weakness when edrophonium is administered. Myasthenic crisis is when there is improvement with a small dose of edrophonium.
Which is the most common cause of penetrating trauma?
Penetrating trauma is an injury caused by a foreign object piercing the skin, which damages the underlying tissues and results in an open wound. The most common causes of such trauma are gunshots and stab wounds.
What’s the difference between penetrating and Perforating trauma?
An injury in which an object enters the body or a structure and passes all the way through is called a perforating injury, while penetrating trauma implies that the object does not pass through 4). Perforating trauma is associated with an entrance wound and an often larger exit wound.
When to use preliminary assessment for penetrating trauma?
Preliminary assessment and care: See “Preliminary assessment and care” in “ Approach to penetrating abdominal trauma “ above. Stab wounds: Patients with no signs of severe vascular or organ injury can be safely observed. Stab injuries (due to sharp objects like knives, vehicular parts in road traffic accidents, rods, etc.)
How is ultrasonography used to treat penetrating trauma?
Ultrasonography has been widely used in the assessment of patients with blunt trauma, but it has only recently been used in the assessment of patients with penetrating injuries. In these cases, the study is performed using the focused assessment with sonography for trauma (FAST).
