Barium sulfate is used to visualize the GI tract.105 Barium sulfate should be avoided in a patient with GI obstruction. It is insoluble and nontoxic but is a soluble compound, which is toxic and may lead to death. Constipation may be detected on oral and rectal administration, and is remedied if a large amount of water is given to the patient. A barium sulfate enema causes electrocardiogram abnormalities. Pneumonitis or granuloma formation are reported during accidental aspiration into lungs. Hypersensitivity reactions also have been reported.106... 

At less than 2% in the clinical investigations acute renal failure, atrial fibrillation, cerebrovascular accident, sepsis, meningitis, psychotic disorder, suicidal ideation, respiratory distress, rhabdomyolysis, electrocardiogram abnormal, stupor, loss of consciousness, incoherent, clonic convulsion and grand mal convulsion. Rare instances of fatal pneumonia aspiration and suicide attempt were reported (<1%).

Electrocardiogram (ECG) May be normal or could show numerous abnormalities including acute ST-T-wave changes from myocardial ischemia, atrial fibrillation, bradycardia, and LV hypertrophy. 

Monitor electrocardiogram continuously in patients with cardiac abnormalities until serum potassium levels drop below 5 mEq/L (5 mmol/L) or cardiac abnormalities resolve. Evaluate serum potassium and glucose levels within 1 hour in patients who receive insulin and dextrose therapy. Evaluate serum potassium levels within 2 to 4 hours after treatment with SPS or diuretics. Repeat doses of diuretics or SPS if necessary until serum potassium levels fall below 5 mEq/L (5 mmol/L). Monitor blood pressure and serum potassium levels in 1 week in patients who receive fludrocortisone. 

The only way to determine if a comatose patient has SE is by EEG. EEG monitoring should be used for patients who remain unconscious after initial antiepileptic treatment, and for those who received a long-acting paralytic agent or require prolonged therapy for RSE. Treatment should never be delayed while awaiting EEG results. An electrocardiogram (ECG) should be obtained to rule out cardiac dysfunction when hypotension or an abnormal heart rate is observed.

The cardiac sensitization test is based on the observation that some halocarbons make the mammalian heart abnormally sensitive to epinephrine, resulting in ectopic beats and/or ventricular fibrillation, which may result in death. Effects are monitored with electrocardiograms (EKG). The dose of administered epinephrine results in blood levels that may be approximately ten times endogenous levels and is close to the threshold for inducing cardiac effects in the absence of the test chemical.

I interviewed John two days before we started and decided he was psychiatrically normal. His physical exam, lab work, electrocardiogram (EKG), and electroencephalogram (EEG) were all devoid of abnormalities, and he reassured us that he was free of any physical symptoms. 

Hoder et al. (1984) studied clonidine in seven newborn infants with neonatal narcotic abstinence syndrome and found no significant changes in blood pressure, pulse, or electrocardiograms (EKG) in any of the seven infants. One infant had a transient abnormal eye exam and two infants developed a transient mild metabolic acidosis. On follow up 4-9 months later, four infants were found to be developmentally age appropriate. However, Huisjes et al. (1986) reported that 22 children exposed in utero to clonidine as result of treatment for maternal hypertension had increased sleep disturbances and hyperactivity, compared to a control group at a mean age of 6 years. It is unclear whether these differences were a direct effect of clonidine on prenatal development. More sophisticated preclinical studies need to be done in this area. At best the level of short-term and long-term safety regarding clonidine is level C. 

Before initiating treatment, obtain a medical history and a psychiatric history. Baseline laboratory studies are also indicated if they have not already been completed as part of the initial evaluation of the patient. An evaluation for the presence of any abnormal movements is also advisable. An electrocardiogram should be considered for patients with a history of cardiac problems.
