Initial symptoms as predictors of esophageal injury in alkaline corrosive ingestions.

The predictive value of initial clinical evaluation in the management of alkaline corrosive ingestion remains unclear. This multicenter study was designed to determine if specific clinical signs and symptoms following ingestion of alkaline corrosives could predict significant esophageal injury. Alkaline corrosives were defined by a pH greater than or equal to 12. Signs and symptoms previously suggested as predictive of significant esophageal injury were documented on a standardized data form. Esophagoscopy reports were reviewed blinded to initial symptoms. Three hundred thirty-six alkaline-corrosive ingestions were analyzed. The mean number of symptoms reported in patients who did not have esophagoscopy was 1.2, in patients who had esophagoscopy was 3.0, and in patients that had visualized second or third degree esophageal burns was 4.8. Of 88 patients who had esophagoscopy, 63 (72%) had both the esophagoscopy report and initial symptom assessment available. Esophagoscopy was positive, defined as second or third degree esophageal burns, in 18 of 63 cases (29%). All patients with significant burns were symptomatic. No single or group of initially reported signs and symptoms could identify all patients with potentially serious esophageal burns.

Serum determinations in toxic isopropanol ingestion.

A toxic dose of isopropyl alcohol was ingested by six male mongrel dogs to evaluate the relationship between acetone production and isopropyl degradation. Maximal serum isopropyl levels were achieved approximately 2 to 3 hours after ingestion of 60 mL of 70% isopropyl alcohol. Acetonemia occurred rapidly in the serum (within 15 minutes of ingestion) and continued to rise after isopropanol levels plateaued. The levels of acetone and isopropanol correlated positively throughout the study model with an r of .54 (P less than .001). It is concluded that there is a positive relationship between acetone production and isopropyl metabolism in the setting of a toxic ingestion of isopropanol. Acetone's persistence as a serum marker may be beneficial in identifying isopropyl hours after a suspected ingestion.

A study of iron complexation in a swine model.

The treatment of iron poisoning consists of supportive care and efforts to remove or retard the absorption of iron from the gastrointestinal tract. A standard but rarely challenged treatment is to render the unabsorbed iron less soluble by complexing it with bicarbonate or phosphate solution. Another therapy is the use of oral deferoxamine. Bicarbonate and phosphate therapy are known to be associated with adverse outcomes if used inappropriately. Is their use justified? To closely simulate a potentially toxic iron overdose in a 24-month-old child, a swine model was used. Twenty fasted castrated male pigs weighing an average of 14.6 kg (+/- 3.0 kg) were orally dosed with 300 mg/kg FeSO4 (60 mg Fe/kg) and randomly placed into 1 of 4 treatment groups receiving 50 ml of distilled water (control), 5% sodium bicarbonate, 5% sodium dihydrogen phosphate, or deferoxamine (10 g). Sequential serum iron levels were obtained at 0, 1, 2, 4, and 6 hr. There were no significant differences in the absorption of iron, as reflected by serum iron concentrations, in the bicarbonate and phosphate groups when compared to the control group (p greater than 0.05). Deferoxamine therapy reduced iron serum concentrations, ie iron absorption, significantly (p less than 0.05) when compared to the control, bicarbonate and phosphate groups. This study provides evidence that efforts to form digestive tract complexation of iron with bicarbonate or phosphate are of no value.

Accidental childhood poisoning: influence of the type of caretaker on etiology and risk.

The primary audience of poison prevention programs is the parent(s) of children less than 6 years of age. Literature review reveals few references assessing other caretakers as risk factors in childhood poisoning. The frequency and severity of calls to the poison center by nonparental caretakers was studied. A total of 4,205 poisoning cases involving children under 6 years of age were analyzed. In 11.9% of the cases the caretaker at the time of exposure was someone other than the parents and the site of the exposure was other than the child's home. Of the 3,702 cases where the exposure occurred while the child was supervised by the parents in their home, 90.2% were treated in the home and 72.4% required dilution only. Grandparents represented 39.6% of caretakers other than the parents. In these cases 44.6% required treatment beyond dilution, indicating more serious exposures in this group. Ingestion of cardiovascular drugs occurred in 12.3% of calls from grandparents as opposed to 0.7% of calls initiated by parents. Poisoning exposures involving children under six years of age, where the caretaker is other than the parents, and the site is other than the child's home, are often more serious. Poison prevention information programs are needed to reduce the risk factors among this group.
