Despite elderly people being the most frequently encountered patient group in prehospital emergency medicine, education about Introduction their care takes up a disproportionately small amount of postgrad- uate and continued professional developed curriculums.

The use This chapter will discuss the challenges of managing elderly of prehospital services by the elderly is four times that of younger patients in the prehospital environment.

The key physiological changes of age relevant to emergency management are those which affect the cardiovascular, respiratory and musculoskeletal systems (Table 30. It is important to note 4 Healthcare professional attribution error that these changes are in addition to and must be considered Healthcare professionals are repeatedly guilty of attribution error alongside those related to chronic diseases common in elderly when assessing elderly people.

Normal hepatobiliary findings are characterized by the immediate demonstration of hepatic parenchyma and rapid clearance of cardiac blood-pool activity purchase doxazosin 2mg without a prescription, followed sequentially by activity in the intra- and extrahepatic biliary ductal system 4mg doxazosin with mastercard, gallbladder cheap doxazosin 1mg amex, and upper small bowel. Gallbladder filling implies a patent cystic intrahepatic biliary tree and common bile duct must contain radioactive bile, and the tracer activity should be present in the small bowel at the time of morphine injection. Contraindications to the use of morphine include increased intracranial pressure in children (absolute), respi- ratory depression in nonventilated patients (absolute), mor- phine allergy (absolute), and acute pancreatitis (relative). The study involves an intravenous administration of sincalide, and multiple meth- odologies exist. The best-validated reference dataset with the greatest number of healthy volunteers points to an infusion of 0. The effectiveness of this method in chronic gallbladder disease has not been reported to date. This methodology is the only one that has a pro- spective, randomized study that supports its use in patients with chronic acalculous gallbladder disease. When patient preparation induces preferential bile flow to the gallbladder (such as in cases of sincalide pretreatment), activity in the small intestine may not be seen during the first hour (or even longer than 2 h) in healthy individuals (91). The hallmark of acute cholecystitis (acalculous as well as calculous) is persistent gallbladder nonvisual- ization after 3–4 h of passive imaging or 30 min after morphine administration. A pericholecystic hepatic band of increased activity (rim sign) is a sign of severe late-stage acute cholecystitis and has been associated with severe phlegmonous or gangrenous acute cholecystitis, a surgical emergency (92). Chronic cholecystitis and clinical settings associated with physiologic failure of the gallbladder to fill with radiotracer (e. In chronic cholecystitis, the gallbladder will usually be seen within 30 min of morphine administration or on 3- to 4-h delayed images, whereas true cystic duct obstruction (acute cholecystitis) will result in persistent gallbladder nonvisualization. A gallbladder that is not visualized until after the time that the bowel is visualized correlates significantly with chronic cholecystitis. Delayed biliary-to-bowel transit beyond 60 min raises suspicion of partial obstruction of the common bile duct, although this may be seen as a normal variant in up to 20% of individuals. With high-grade common bile duct obstruction, there is usually prompt liver uptake but no secretion of the radiotracer into biliary ducts. With partial biliary obstruction, radiotracer fills the biliary system but clears poorly proximal to the obstruction by 60 min or on delayed images at 2–4 h or with sincalide. Severe hepatocellular dysfunction may also demon- strate delayed biliary-to-bowel transit. A bile leak is present when tracer is found in a loca- tion other than the liver, gallbladder, bile ducts, bowel, or urine. Leakage may be seen more easily using a cinematic display or decubitus positioning, as described above. Biliary atresia can be excluded scintigraphically by dem- onstrating transit of radiotracer into the bowel. Failure of tracer to enter the gut is consistent with biliary atresia but can also be caused by hepatocellular disease or immature intrahepatic transport mechanisms. Renal or urinary excretion of the tracer (especially in a diaper) may be confused with bowel activity and is a potential source of erroneous interpretation. During a hepatobiliary scan, activity may reflux from the duodenum into the stomach. Bile reflux that is marked and occurs in a symptomatic patient corre- lates strongly with bile gastritis, a cause of epigastric discomfort. After cholecystectomy, sphincter of Oddi dysfunction has the appearance of partial common bile duct obstruc- tion. Pretreatment with sincalide or morphine may improve the sensitivity for its detection. Various visual, quantitative, and semiquantitative scintigraphic param- eters of bile clearance have been used in conjunction with image analysis. The causes of a false-positive study (gallbladder non- visualization in the absence of acute cholecystitis) include: a. Severe intercurrent illness (despite sincalide pre- treatment and morphine augmentation) f. Rapid biliary-to-bowel transit (insufficient tracer activity remaining in the liver for delayed imaging) h. Previous cholecystectomy The causes of a false-negative study (gallbladder vis- ualization in the presence of acute cholecystitis) are rare but include: a. A bowel loop simulating gallbladder (Drinking 100–200 mL water may remove the radiophar- maceutical from the duodenum and allow differ- entiation of gallbladder from bowel. A right lateral view should be obtained to better distinguish activity in the duodenum from that of the gallbladder. The presence of the dilated-cystic-duct sign simu- lating gallbladder (If this sign is present, morphine should not be given. Description of findings Include the appearance of the liver, intrahepatic ducts, common bile duct, the presence and time of tracer appear- ance in the gallbladder or small bowel, any unusual activity (e. Study limitations (patient reactions to drugs adminis- tered) If there is an allergic or other adverse reaction to the radiopharmaceutical or other administered pharmaceuticals, the reaction must be clearly stated in the findings and impres- sion sections of the report. Gastrointestinal symptoms elicited by sincalide infusion are related to the rapid infusions and are not observed with the recommended slower infusion techni- ques of 45 and 60 min. Gastrointestinal symptoms occurring during the shorter sincalide infusion have no specificity for gallbladder pathology (93) and should not be part of the study report. However, no information about possible pla- cental crossover of hepatobiliary compounds is available. Impression The impression should be concise and as precise as pos- sible, should address the clinical question, should provide a differential diagnosis, and should make recommendations if appropriate. Any urgent or unexpected findings should be directly communicated to the referring physician, and this communication should be documented. Radiation dosimetry in adults, children, and pregnant or potentially pregnant patients is presented in Tables 2–4. The physician must consider the indication for the test, the potential benefit of information it may provide toward improved care of the patient, and the potential risk it may pose to the fetus.

Abnormal gallblad- der nuclear ejection fraction predicts success of cholecystectomy in patients with biliary dyskinesia. Biliary dyskinesia: a study of more than 200 patients and review of the literature. Chronic acalculous biliary disease: cholecystokinin cholescintigraphy is useful in formulating treat- ment strategy and predicting success after cholecystectomy.
