In this position, the gravid uterus compresses the aorta, decreasing blood flow to the uterus, and the vena cava, reducing venous return. If a pregnant patient undergoes surgery in the supine position, there is the concern of the supine hypotensive syndrome. Victoria Bradford, Robert Gaiser, in Perioperative Medicine (Second Edition), 2022 Should the Pregnant Patient Undergoing Surgery During Pregnancy Be Tilted? Negative screening does not rule out the presence of certain benzodiazepines, as mentioned above. Urine screening may confirm the presence of benzodiazepines or their metabolites. Co-ingestion of other toxic substances, concurrent trauma, or other underlying medical conditions significantly alter the diagnostic and therapeutic approach. Serum acetaminophen and salicylate concentrations should be performed for all intentional overdose patients. Routine laboratory analysis should include a complete blood count and measurement of electrolytes, blood urea nitrogen, creatinine, glucose concentrations, and pregnancy testing for women of childbearing age. Frequent vital sign and neurologic evaluations are necessary. Semi-comatose patients should be placed in the left lateral, head-down position to minimize the risk for aspiration. Supplemental oxygen, continuous pulse oximetry, and parenteral thiamine, dextrose (or rapid fingerstick glucose determination), and naloxone should be considered for patients with altered mental status or seizures. All patients should have continuous cardiac monitoring, an intravenous line established, and electro- cardiography performed. Patients with significant CNS or respiratory depression should have their airways protected, breathing assisted, and cardiovascular support provided supportive as necessary. Treatment for benzodiazepine overdose is primarily supportive. ![]() FATOVICH MD, in Haddad and Winchester's Clinical Management of Poisoning and Drug Overdose (Fourth Edition), 2007 Supportive Measures and Laboratory Testing Of those listed below, which is not a protozoan? a.ġ.

Palpation of the heart is among the oldest physical examination techniques, having been recorded as early as 1550 BC by ancient Egyptian physicians (along with palpation of the peripheral pulses). Although this chapter refers to these studies to make certain points, only those movements easily palpable at the bedside are discussed. These precise and sensitive instruments could detect very small movements of the body wall, many of which are inconspicuous to the clinician’s hand. Much of the science of heart palpation is based on impulse cardiography and kinetocardiography, research tools from the 1960s that precisely timed normal and abnormal precordial movements and compared them with hemodynamic data and angiograms of the right ventricle and left ventricle (LVs).
