  • Acute obstruction of the upper airway from trachea, a foreign body or Iaryngospasm may lead to death in a few minutes. The immediate restoration of an adequate airway in these patients may be lifesaving. Spontaneous respiration by means of a needle inserted into the trachea was studied in 21 rabbits using 16, 18, and 20 gauge extrcatheters. The results are as follows; 1) Airway resistance was markedly increased in all experimental animals. consequently tidal volume was also significantly decreased, but this seems to be compensatory by increased of respiratory frequency in l6G group. 2) Blood gas analysis revealed adequate pulmonary ventilation through the constricted airway (about 1/3 of normal sized trachea) during 60 minutes. In the other hand, hypercarbia, hypoxemia, and metabolic acidosis were developed in the group with severe constriction of the upper airway (about 1/4-1/6 of normal sized trachea). 3) The further study is postulated to confirm the the possibility of application of needle trcheostomy in man, but the rabbits were tolerable to the constricted airway with a small sized needle (l6G) into the trachea for 60 minutes.

  • Authors observed clinically 34 cases of the corrosive esophagitis caused by various corrosive agents at Kyung Hee University Hospital from Aug. 1978 to Dec. 1980. The results obtained were as follows; 1. Among the 34 patients, male was 19 (55.9%) and female 15(44.1%). Most frequently found age was 3rd decade. 2. 18 cases(52.9%) came to the hospital within 24 hours after ingestion of the agents, and 13 cases(38.2%) within 2 to 7 days. 3. Seasonal distribution showed most frequently in spring(35.3%). 4. The moment of the accident was suicidal attempt in 27 cases(79.4%) and misdrinking in 7 cases(20.6%). 5. Acetic acid was a most commonly used agent, showing 23 cases(67.6%), lye and insecticides were next in order. 6. Common chief complaints were swallowing difficulty and sore throat. 7. The average hospital days was 14.8 days. 8. Esophagogram was performed between 3 to 7 days after ingestion in 13 cases(38.2 %), findings were constrictions on the 1st narrowing portion in 4 cases(30.8%) and within normal limits in 3 cases(23.1%). 9. Esophagoscopy was performed in 31 cases(91.2%) between 2 to 7 days after ingestion, which revealed edema and coating on entrance of the esophagus in 9 cases (29.0 %). Diffuse edema on entire length of the esophagus and within normal limits were next in order. 10. Laboratory results were as follows: Anemia was in 1 cases(2.9%), leukocytosis. in 21 cases (61.8%), increase ESR in 9 cases (26.5%), markedly increased BUN and creatinine in 3 cases (8.8%), and hypokalemia in 1 cases(2.9%). Proteinuria in 10 cases(29.4%) hematuria in 4 cases(l1.8%), and coca cola urine in 3 cases (8.8%). 11. Associated diseases were 3 cases(8.8%) of cancer, 1 cases (2.9%) of diabetes mellitus, and 1 cases(2.9%) of manic depressive illness. 12. Various treatment was given: Esophageal and gastric washing in 23 cases(67.6%) for the emergent treatment, antibiotics in 32 cases(94.1%), steroids in 30 cases(88.2%), bougienation in 5 cases(14.7%), hemodialysis in 1 case(2.9%), and partial esophagectomy with gastrostomy and gastroileal anastomosis in 1 cases(2.9%). 13. Serious complications were observed in 9 cases (26.5%), consisted of 6 cases(17.6%) of esophageal stricture, 1 cases(2.9%), of aute renal failure, 1 cases (2.9%) of pneu momediastinum with pneumonia, and 1 cases (2.9%) of pneumonia.

  • There are a lot of dental emergency situations and accidental aspiration or ingestion of a dental instrument is one of the common accidents in dental practice especially on disabied or pediatric patient with negative behavior. Most of ingested foreign bodies pass through the gastrointestinal tract spontaneously, but some of them (about 20%) need endoscopic or surgical removal. This is a case of an accident during the treatment of a 18 months male patient with caries of anterior deciduous teeth. During the treatment, the gauze was used by waterproofing instead of a rubber dam. #4 round bur (approximately 2.2cm long) which was put on the tray was cling to the gauze and the bur was fell into the patient's throat. The bur was 2.2cm long and very sharp so it could not be passed spontaneously through the pylorus, so we tried to remove the bur by esophagogastroduodenoscopy. Endoscopic removal of foreign bodies in the upper gastrointestinal tract is an effective and safe procedure.
