For example, naloxone hydrochloride injection (evzio) was food and drug administration (fda)-approved for this purpose. 20 it is too early to determine the public health impact of this approach for treatment of opioid overdoses. Stimulant (cocaine and amphetamines) intoxication desired outcomes of stimulant intoxication treatment are appropriate management of medical and psychiatric problems. Medical problems include hyperthermia, hypertension, cardiac arrhythmias, stroke, and seizures. Some medical problems are related to route of administration, such as nosebleeds with intranasal administration and infections with iv administration. Psychiatric effects include anxiety, irritability, aggression, and psychosis. Notably, stimulant intoxication is the only stimulant use disorder for which specific pharmacotherapy has demonstrated effectiveness. Recommended medications in acute settings include benzodiazepines, aspirin, nitroglycerin, nitroprusside, and phentolamine. 21 the american heart association guidelines indicate that acute use of β-blockers is not recommended and may lead to worsening cocaine-related chest pain (caused by coronary vasoconstriction) and hypertension secondary to unopposed alpha activity. Cocaine is short acting, and a single benzodiazepine sedativehypnotic may be sufficient treatment for anxiety reactions. Depending on the half-life of the benzodiazepine, one or more sequential doses may be required for longer acting amphetamine intoxication. Antipsychotics are indicated when psychosis is present, and psychosis usually responds quite rapidly in the absence of other co-occurring psychiatric disorders. Cannabinoid (marijuana, etc) intoxication there are no established treatment recommendations for cb intoxication. Symptomatic treatment (eg, tachycardia, anxiety, paranoia, and psychosis) is the commonly used approach. The exception is potent synthetic cannabinoids, which may require aggressive benzodiazepine treatment for intense symptoms of anxiety or psychosis. These intense psychiatric symptoms have been theorized to result either from the potent full-agonist cannabinoids that are used to prepare them, or possibly due to the chapter 36  |  substance-related disorders  551 table 36–5 clinically relevant drug interactions with substances or medications used to treat substance use disorders drug interacting drug type of interaction and appropriate action amphetamines (including dextro- and methamphetamine) maois (phenelzine, selegiline, tranylcypromine, possibly linezolid) sodium bicarbonate pharmacodynamic interaction resulting in an increased blood pressure.

essay school admission Specific lesions and lesion-specific management are covered in more detail in section v. B. Congestive heart failure 1. Clinical findings. Chf in the neonate (or in a patient of any age) is a clinical diagnosis made based on the existence of certain signs and symptoms rather than on radiographic or laboratory findings (although these may be supportive evidence for the diagnosis). Signs and symptoms of chf occur when the heart is unable to meet the metabolic demands of the tissues. Clinical findings are frequently due to homeostatic mechanisms attempting to compensate for this imbalance. In early stages, the neonate may be tachypneic and tachycardiac with an increased respiratory effort, rales, hepatomegaly. And delayed capillary refill. In contrast to adults, edema is rarely seen. Diaphoresis, feeding difficulties, and growth failure may be present. Finally. Chf may present acutely with cardiorespiratory collapse, particularly in "left-sided" lesions {see v.A.). Hydrops fotalis is an extreme form of intrauterine chf {see chap. 26). 2. Differential diagnosis. The age when chf develops depends on the hemodynamics of the responsible lesion. When heart failure develops in the first weeks of life, the differential diagnosis includes (i) a structural lesion causing severe pressure and/or volume overload, (ii) a primary myocardial lesion causing myocardial dysfunction, or (iii) arrhythmia. Table 41.3 summarizes the differential diagnoses of chf in the neonate. C. Heart murmur. Heart murmurs are not uncommonly heard when examining neonates. Estimates of the prevalence of heart murmurs in neonates vary widely from < 1% to >50% depending on the study. Murmurs heard in newborns in the first days oflife are often associated with structural heart disease of some type, and therefore may need further evaluation, particularly if there are any other associated clinical symptoms. Pathologic murmurs tend to appear at characteristic ages. Semilunar valve stenosis (systolic ejection murmurs) and atrioventricular valvular insufficiency (systolic regurgitant murmurs) tend to be noted very shortly after birth, on the first day of life.
