(For more, see the What is being tested? section.) A hemoglobin test may be used to: Screen for, diagnose, and measure the severity of anemia (low RBCs, hemoglobin and hematocrit) or polycythemia (high RBCs, hemoglobin and hematocrit) Monitor the response to treatment of anemia or polycythemia.
Calcium channel blockers prevent calcium from entering into the heart muscle cells, and into the smooth muscle cells that cause blood vessels to constrict. This relaxing effect results in the dilation of blood vessels, and a reduced force of contraction of the heart muscle.
Neuromuscular blocking agents. What are Neuromuscular blocking agents. Neuromuscular blocking agents bind to acetylcholine receptors postsynaptically and inhibit the action of acetylcholine. This blocks neuromuscular transmission and causes paralysis of the muscle. Neuromuscular blocking agents are used as an adjunct to anesthesia, only when artificial ventilation is available, to produce muscle relaxation in order to prevent movement of muscle during surgery.
