Method: 73 patients were performed gastric lavage by an improved technique with new equipment. All of the patients were monitored clinical signs (pulse rate, blood pressure, respiratory rate, SpO2, lung sound...) and tested (blood count, electrolyte, ECG, chest X-ray, toxic screening...) before and after doing gastric lavage. The results were compared to a retrospective study in 1998-2000 we found that complications are reduced significantly from 6.21% to 2.74%. In addition, there was not any severity complication; we only met two cases hypokalemia after doing gastric lavage. Conclusion: the improved technique with new equipment of gastric lavage would be safe for the patients, reduce significantly complication, and easy to implement.

In this paper, the design of a safe and multifunctional gastric lavage machine is presented. The microprocessor samples and analyzes the air pressure, time rate of pressure change, volume, and limit signals, then controls the relays and the electromagnetism valves to adjust the operating condition in real time. The machine has many functions, such as gastric lavage, aspirating, digital displaying, alarming, and so on.

Gastric lavage is one of gastrointestinal decontamination methods which have been controversial in the clinical toxicology field for a long time. Expert groups of American and European clinical toxicologists have published the position papers regarding gastric lavage three times since 1997. They recommended that gastric lavage should not be used as a routine procedure in the management of acute intoxication, because they thought that there is no certain evidence of improving clinical outcome by its use. However, the studies they reviewed were not well-controlled randomized trials, which cannot be conducted in the clinical toxicology field due to variability of patients and ethical problems. Therefore, the results from these studies should be interpreted with caution. They also insisted that gastric lavage can be undertaken within 60 minutes of ingestion. The limitation of one hour after ingestion is too arbitrary and may cause a lot of misunderstanding. Formation of pharmacobezoar or gastric hypomotility after ingestion may significantly delay the gastric emptying time so that gastric lavage can be useful even after several hours or more in case of highly toxic substances or severe intoxication. Furthermore, as there are a number of serious intoxication by toxic pesticides with large amount in suicidal attempts in Korea, it seems that gastric lavage may be used more frequently in Korea than in Western countries. When deciding whether or not to use gastric lavage, all the indications, contraindications, and possible adverse effects should be taken into account on the basis of risk-benefit analysis. If the procedure is decided to be done, it should only be performed by well-trained experts.

Mucinous adenocarcinoma is a rare histologic type of gastric carcinoma. Most mucinous gastric carcinoma is diagnosed by histology after surgical resection. However, in this report, we preoperatively predicted the type of a tumor (mucinous type) from its characteristic endoscopic finding. An endoscopic examination showed a cauliflower-like mass on the upper body of the posterior wall. At first we could not find the mass because it was covered with a thick mucin-like substance. After gastric lavage and mucin aspiration we found a tumor mass which was surrounded with a characteristic mucin pool. Abdominal CT showed a 6 cm sized-mass connected with the gastric fundus. Total gastrectomy with esophagojejunostomy was performed. The pathology of the tumor proved to be a mucinous adenocarcinoma.

PURPOSE: Plasma cholinesterase is a sensitive measure determining the severity of organophosphate intoxication. The author evaluated the usefulness of the plasma cholinesterase level as a prognostic indicator of the severity of organophosphate intoxication. METHODS: From June 1999 to May 2001, 55 patients presented with organophosphate insecticide intoxication to the Emergency Medical Center of the Chonnam National University Hospital, and these were enrolled in this study. The plasma cholinesterase activities of these 55 patients were determined at the time of presentation. The relationships between the plasma cholinesterase level and the clinical variables of organophosphate toxicity, quantity of ingested poison, elapsed time to gastric lavage, and the APACHE score at the time of hospitalization were analyzed. RESULTS: The plasma cholinesterase activity significantly decreased in association with the degree of toxicity of the poison (p<0.001), elapsed time to gastric lavage (p<0.001), and the quantity of organophosphate ingested (p=0.013). In the 55 patients, lower plasma values of cholinesterase were observed in patients with longer durations of mechanical ventilation (r=-0.717, p<0.001) and in patients who developed pneumonia during treatment (r=-0.538, p<0.001). Also, decreased cholinesterase activity correlated with a higher APACHE score (r=-0.672, p<0.001). CONCLUSION: These results suggest that immediate determination of the plasma cholinesterase level at the time of hospitalization may be useful as a prognostic indicator in patients with organophosphate intoxication.

Chlorophenoxy herbicide poisoning is uncommon, but may produce severe sequelae. It's treatment is primarily the same as that used for poisonings with other drugs; gastric lavage, activated charcoal, etc. However, it's secondary treatment to enhance elimination has two options, alkaline diuresis or hemodialysis. We experienced a patient who had been poisoned with chlorophenoxy herbicide and had severe symptoms like comatose mentation, acute renal failure, rhadomyolysis, etc. The patient was treated by hemodialysis for 5 days and recovered from the acute state.
