Advances in the Management of the Critically Injured Patient in the Operating Room

IntroductionCardiovascular shock refers to a critical condition that occurs when a patient's heart suddenly fails to pump blood as required by the body. This rare but fatal condition is mostly caused by heart attack and is linked to high death rate [1,2]. The fluid administration that forms the firstline of therapeutic strategy does not offer enough stability for the condition of the patient, and the adrenergic agents are regularly needed to correct hypertension [3]. Among the most frequently used agents are dopamine and norepinephrine. Both dopamine and norepinephrine affect the alpha-adrenergic and beta-adrenergic receptors, though to varying degrees. The effects of alpha-adrenergic receptors lead to increased vascular tone. However, it could decrease the cardiac output as well as the regional flow of blood, particularly in cutaneous, renal, and splanchnic beds [4].On the other hand, beta-adrenergic effects assist in the maintenance of blood flow through inotropic and chronotropic effects as well as increasing splanchnic perfusion. This stimulation from the betaadrenergic effects can bring out the unwanted consequences, including an increase in the cellular metabolism and immunosuppressive effects [5]. Besides, dopamine arouses dopaminergic receptors, which leads to a uniformly bigger rise in renal and splanchnic perfusion, which can expedite lung edema tenacity. Conversely, the stimulation caused by dopamine could lead to negative immunological effects by modifying hypothalamic-pituitary function, leading to a patent drop of prolactin as well as the level of hormones [6].Hypothetically, norepinephrine and dopamine have varying effects in the splanchnic, kidney and pituitary axis, though the medical consequences of the implied differences are not certain [7]. Experts have recommended that any of the two compounds may be chosen first and applied as a vasopressor in patients suffering from shock. Studies have Comparing the Use of Dopamine and Norepinephrine in Shock Treatment AbstractBackground: The vasopressor agents, such as norepinephrine and dopamine have been endorsed as the standard choice for shock treatment. However, there is controversy regarding the use of vasopressor agents for shock treatment. Considering the use of norepinephrine over dopamine, the present study aimed at assessing the reasons for the reduced death rate among the patients who were in shock.

“…This provided enough room and time for drug exposure. After 28 days, the physician in charge was left with the vasopressor agent choice [14].…”
