However rheumatoid arthritis diet supplements purchase discount trental, the majority of these patients were acutely poisoned and it is possible that chronically poisoned patients may respond differently arthritis medication nabumetone purchase 400mg trental free shipping. Treatment failures have been attributed to inadequate or delayed dosing rheumatoid arthritis blisters purchase trental online pills, moribund clinical state before digoxin-specific antibody Fab therapy, pacemaker-induced dysrhythmias, and incorrect diagnosis of digitalis toxicity [36,38]. Digoxin-specific antibody Fab dosage (number of vials) calculations are based on the serum digoxin concentration or estimated body load of digoxin. The body burden can be estimated from the milligram amount of an acute ingestion or by multiplying the post-distribution serum digoxin concentration (ng per mL) by the volume of distribution of digoxin (= 5. In the largest prospective study of Fab for digoxin poisoning (n = 150, mean serum concentration of 8 ng per mL), the dose of Fab required to reverse digoxin toxicity was five vials with a range from 3 to 20 vials [36]. A severely toxic patient in whom the quantity ingested acutely is unknown should be given 5 to 10 vials at a time and the clinical response observed. In contrast, patients with chronic therapeutic overdose often have only mildly elevated digoxin concentrations and respond to one to two vials of digoxin-specific antibody Fab. The recommended dose for a given patient can be determined using the tables in the package insert or by contacting a regional poison center or toxicology consultant. Free digoxin concentrations are decreased to zero within 1 minute of digoxin-specific antibody Fab therapy, but total serum digoxin concentrations may be markedly increased [36,40]. Because most assay methods measure total (bound and free) digoxin, very high digoxin concentrations are seen after digoxin-specific antibody Fab treatment, but they have no correlation with toxicity [40]. Serum concentrations may be unreliable for several days after digoxin-specific antibody Fab therapy [41]. In patients with renal failure, elimination of the digoxin–Fab complex is prolonged and free digoxin concentrations gradually increase over 2 to 4 days after digoxin-specific antibody Fab administration [43]. In one report of 28 patients with renal impairment given digoxin-specific antibody Fab, only one patient had recurrent toxicity, which occurred 10 days after digoxin-specific antibody Fab treatment and persisted for 10 days [44]. Monitoring of free digoxin concentrations may be beneficial for titrating effect in those patients reliant on the inotropic action of digoxin, detecting rebound toxicity in patients with renal impairment, assessing the need for further treatment with digoxin-specific antibody Fab, or in guiding the reinstitution of digoxin therapy [45]. Digoxin-specific antibody Fab therapy has been associated with mild adverse drug events such as rash, flushing, and facial swelling [36,38]. Before digoxin-specific antibody Fab administration, an asthma and allergy history should be obtained. If a patient with a positive skin test is dying, however, the risk–benefit ratio obviously favors treatment [38]. A precipitous drop in the serum potassium, recurrence of supraventricular tachydysrhythmias previously controlled by digoxin, and development of cardiogenic shock in a patient dependent on digoxin for inotropic support have all been associated with digoxin-specific antibody Fab therapy [36]. In most, it was attributed to an inadequate initial dose of digoxin-specific antibody Fab dosing and reversed with a repeat dose. Those with elevated drug concentrations resulting from chronic therapy who are hemodynamically stable can be observed on a telemetry unit. Discontinuing the use of digoxin or decreasing the dose, modifying predisposing factors, and closely monitoring subsequent therapy are necessary to avert further toxic episodes.

Many poisonings result from accidental dermal contamination during agricultural use of pesticides [1]. Food-borne exposures have produced epidemics such as “Ginger Jake paralysis” (delayed neuropathy) because of contamination of an alcoholic drink with triorthocresyl phosphate [3] and an epidemic affecting over 2,000 people with mild-to-moderate symptoms related to the use of aldicarb on watermelons; an insecticide that is no longer made in the United States and will no longer be available in 2018 [4]. Enzyme regeneration occurs by either de novo synthesis, hydrolysis of the serine–organophosphorus bond, or oxime- aided reactivation. The characteristics and treatment of exposure to these products are covered at the end of this chapter. In general, effects at muscarinic sites are sustained, whereas nicotinic sites are stimulated and then depressed (hyperpolarization block). Signs and symptoms of cholinergic toxicity typically appear when 60% to 80% of cholinesterase activity has been inhibited [6].

The procedure has considerable risks of transplant-related morbidity and mortality with a substantial proportion of patients requiring intensive medical care [1–3]. Thus, knowledge of the basic principles of the transplant procedure and an understanding of potential complications including their differential diagnosis are important for improving the outcomes of critically ill patients after transplantation. The stem cell products obtained from each of these sources are characterized by distinct kinetics of engraftment and recovery of immune function after transplantation. Bone marrow is harvested from the iliac crest under general anesthesia, from appropriate volunteer donors. Engraftment after bone marrow transplant is evidenced by rising neutrophil and platelet counts and occurs between 3 and 4 weeks after transplant. High-dose chemoradiation is given to kill tumor cells that may not be susceptible to conventional-dose cytotoxic therapy. The success of the autologous transplant procedures relies exclusively on the tumor-eradicating potential of the preparative regimen [10].

Adhikari S, Blaivas M: Utility of bedside sonography to distinguish soft tissue abnormalities from joint effusions in the emergency department. This careful monitoring alerts the health care team to changes in the patient’s severity of illness—helping to both diagnose disease and assess prognosis. Careful monitoring also helps the health care team safely apply therapies such as volume resuscitation, vasoactive infusions, and mechanical ventilation. In addition, it reviews noninvasive monitoring of tissue perfusion, with particular attention to gastric tonometry, sublingual capnometry, and transcutaneous oxygen and carbon dioxide monitoring. However, nearly all routine vital signs can now be monitored accurately, noninvasively, and continuously. Over the past decades, the trend for monitoring systems has been toward multipurpose systems that integrate monitoring of a variety of parameters. Multipurpose systems eliminate the need for multiple, freestanding devices—reducing clutter and improving workflow ergonomics at the bedside. These systems also interface with critical care information systems to provide more efficient data management, quality improvement reporting, and in some cases prospective data-driven alerts. An abnormal temperature is frequently the earliest clinical sign of infection, inflammation, central nervous system dysfunction, or drug toxicity. Unfortunately, the type of thermometer and the site where the temperature is taken can affect the accuracy of this vital measurement. Clinicians should understand the impact of the thermometer type and the measurement site on how to interpret the patient’s reported temperature. Indications for Temperature Monitoring the Society of Critical Care Medicine’s Task Force on Guidelines’ recommendations for care in a critical care setting grades temperature monitoring as an essential service for all critical care units [3]. Critically ill patients are at high risk of temperature dysregulation because of debility, impaired control of temperature, use of sedative drugs, and a high frequency of infection. Patients with marked temperature abnormalities should be considered for continuous monitoring; patients undergoing active interventions to alter temperature, such as breathing heated air or using a cooling–warming blanket, should have continuous monitoring to prevent overtreatment or undertreatment of temperature abnormalities. Measurement Sites the goal of temperature measurements is generally to estimate core temperature—the deep body temperature that is carefully regulated by the hypothalamus so as to be independent of transient small changes in ambient temperature. Core temperature exists more as a physiologic concept than as the temperature with an anatomic location. An ideal measurement site would be protected from heat loss, painless, convenient to use, and would not interfere with the patient’s ability to move or communicate. Sublingual Temperature Measurements Sublingual temperature measurements are convenient, but suffer numerous limitations. Although open-mouth versus closed-mouth breathing and use of nasogastric tubes do not alter temperature measurement [4], oral temperature is obviously altered if measured immediately after the patient has consumed hot or cold drinks. Sixty percent of sublingual temperatures are more than 1°F lower than simultaneously measured rectal temperatures; 53% differ by 1°F to 2°F, and 6% differ by more than 2°F. Sublingual measurement is best suited for intermittent monitoring when some inaccuracy can be tolerated. Axillary Temperature Measurements Axillary temperatures are commonly used as an index of core temperature. Although some studies indicate close approximation of the axillary site with pulmonary artery temperatures [5], temperatures average 1. The accuracy and precision of axillary temperature measurements are less than at other sites [6], perhaps due in part to the difficulty of maintaining a good probe position. Before a rectal thermometer is inserted, a digital rectal examination should be performed because feces can blunt temperature measurement. Rectal temperature correlates well in most patients with distal esophageal, bladder, and tympanic temperatures [7]. Rectal temperatures typically respond to induced changes in temperature more slowly than other central measurement sites [8].
