Glossopharyngeal neuralgia, first discribed by Labat in 1928, is a very rare disease of unknown cause. This neuralgia is associated with a characteristic sharp pain of the posterior pharynx, tonsils and larynx, and especially triggered by swallowing action. It is said that this pain is more severe than that of trigerminal neuralgia and the pain may last several up to 30 minutes and the attack repeats intermittently. Diagnosis of glosspharyngeal neuralgia is made by the symptoms and by the elongation of the right side of the styloid process in this case. The glossopharyngeal nerve block by the deposition of local anesthetic solution is useful in the accurate diagnosis of the douleureux or neuralgia in which this nerve is involved and in providing anesthesia for operative intervention upon the posterior third of the tongue. This is a report of a case of glossopharyngeal neuralgia, which did not respond to Tegretol and other analgesic drugs and treated by glossopharyngeal nerve block with 0.5% bupivacaine l.5-2.0 ml. The block was performed every day for 15 days and the neuralgia disappeared without complication.

Tracheostomy is done to treat the acute upper airway obstruction. But when the condition. precipitating tracheotomy has resolved, the tracheal cannula cannot be removed sometimes because of the anatomical change at the tracheotomised tissue. This is described that decannulation is delayed. Delayed decannulation is uncommon but occurs more frequently in young children than in adults. The child who is difficult to decannulate is continuously at risk. His family experiences emotional, social and sometimes economic hardships. Many factors may delay decannulation; a frequent cause is posterior displacement of the: anterior tracheal well above the tracheotomy stoma induced by the position and pressure of the tracheotomy cannula itself. High tracheotomy, subglottic edema, emotional dependence increase of upper air-way resistance and delayed laryngeal development are solo the factors. One of the treatment of the difficult decannulation, T-tube stent was inserted through tracheoplasty. in this report, a 24 months old girl, nasotracheal intubation was used in the attempted decannulation. Radiological and endoscopic evaluation indicated that posterior displacement of the anterior tracheal well above the tracheal stoma was the cause of the delay. Dacalnnulation was achieved after 10 days of the intubation therapy. Etiology of the tracheal stenosis, pattern of respiratory difficulty, technic and patient care of nasotracheal intubation as the therapy of delayed decannulation and the role of anesthesiologists and pediatric intensive care was discussed.

To assess the effect of premedication for pediatric cases, flunitrazepam (Rohypnol) was given to small children under 6 years of age. 70 patients were divided into 4 groups to which the drug was given intramuscularly, 0. 06 mg, 0.1 mg, 0.15 mg and 0. 2 mg per kilogram of body weight, of the drug respectively. The dose was given 30 minutes before anesthesia and the maximum dose was limited to 2.0 mg for each patient if the calculated dose of the drug exceeded this amount. 1) The shortest time of onset of sleep was 5 minutes. The group which fell asleep between 5 and 10 minutes did not respond to needle stimulation. The group which fell asleep between 11 and 15 minutes moved upon needle stimuli but an intravennous needle was inserted without difficulty. 2) The group which fell between 16 and 20 minutes and became sedated after 20 minutes. without asleep was induced by anesthesia with an inhalational agent but aroused by needle stick. The last group was sedated in presence of their guardian only and became uncooperative when they were separated from the latter. 3) The patients were not affected at all with the dose of 0.06mg/kg of flunitrazepam. 4) With the dose of 0. 1 mg/kg, the group under 6 months of age did not sleep and in the; group between 4 and 6 years of age, half did sleep. ) With the dose of 0.15 mg/kg, in the group under the age of one year, 50% of the cases slept and in the group between 2 and 6 years of age, 30% of the cases slept. 6) With the dose of 0. 2 mg/kg, the sleep group was 25% under 1 year of age, 30. 8% between one and 3 years of age and 33% between 4 and 5 years of age, but the maximum. dose given was limited to 2 mg for each case. A tendency to increased effect according to the increase of age was noticed. 7) The optimum dose of the drug was suggested to be 0. 15 mg/kg and if a dose was used of more than 2. 0 mg, it was not needed to increase above this amount for the purpose of sedation. 8) Optimal time for premedication was suggested to be 30 minutes before the induction of anesthesia. 9) Respiratory and circulatory depression were not noticed with the above doses. 10) Endotracheal intuhation was faeilitated without the aid of muscle relaxant in about 30% of cases when 0.15mg)kg Of the drug was given.

Korean Journal of Anesthesiology 1983;16(3):239-245
Attention has been drawn to the possible deliterious effects on operating theatre personnel of breathing in an atmosphere polluted with anaesthetic vapour, in particular, halothane. Whether or not the relation of these effects of anaesthetic vapours has been adequately proved, there is unlikely to be any disagreement that pollution of theatre air with anaesthetic is undesirable. Comparable atmospheric pollution with halothane in the same theatre was studied with and without use of halothane absorber "Aldasorber". The theatre had no device for reducing air pollution. Anaesthetic exhaust fases were drained to the ground. An anaesthetic machine in a semiclosed circle with carbon dioxide absorber was used throughout the anaesthesia. Anaesthesia was maintained with halothane l.0% and 50% oxygen in nitrous oxide, free gas flow rate were oxygen l.5 liter/min and nitrous oxide 1.5 liter/min, Halothane concentrations at various sites of the operating theatre were studied using the method of gas chromatography. 1) Halothane concentrations in the atmosphere of the operating theatre were 0.11 +/-0.07 ppm without halothane absorber and 0.13 +/-0.14 ppm with halothane absorber at the level of 115cm above the operating theatre floor before anaesthesia. 2) Halothane concentrations in the atmosphere of the operating theatre were 7.50 +/-1.32ppm without halothane absorber and 2.82 +/-0.93 ppm with halothsne absorber at the level of 115cm above the operating theatre floor after 3 hours of anesthesia. 3) Comparing this data it was concluded that the concentration of halothane vapour in the operating theatre air after 3 hours of anesthesis could be reduced by 65% W1th halothane absorber Aldasorber.

The recovery process of brain damage caused by an acute severe cerebral hypoxia has been reported in various literatures. And the possibility of complete recovery of such case was said to be good in younger age group than in adult's group. We experienced a case of cardiac arrest of a 12 year old girl during halothane anesthesia induction and the cardiac and pulmonary resuscitation was succeeded promptly. But the hypotensive period persted for few minutes before the diagnosis was made. The condition of the patient after the resuscitation was good except that her unconsciousness state persisted unusually. The proposed appendectomy performed uneventfully and the anesthesia recovery of the patient was carefully observed in our I.C.U. The uncoscious state lasted for 2 days with agitated movements of legs, EEG showed abnormal, irregular patterns but showed no signs of damage of gobus pallidum and putamen. During the first month, the order of recovery of cerebral function was comatous state, swallowing, eating, and urination. The cerebellar dysunction was prominent. Then recovery of amnesia and defection followed. Speech and gate started to regain in the 26 and 36 post-operative day respectively. Writing function started recover quickly with the recovery of speech function, which occurred in 4 to 6 post-operative months. Recovery of intelligence was slowest and gradually reached to the intelligent level of 11 year old child in one year. It was found the primitive function recovered first and the highly cultivated function recovered last.

Chang Kyum KIM ; Woon Hyok CHUNG
Korean Journal of Anesthesiology 1978;11(4):289-293
Althesin(CT 1341), a new steroid anesthetic, was tried clinically as an induction agent. All 24 patients were in the physical status class 1 by A.S.A. classification. Dosage of althesin given intravenously was 50ul/kg B.W. and the injection speed for the given dose was 15 seconds. The following results were obtained. 1) Induction time was 42+/-19. 7 seconds. 2) No significant changes in pulse rate were found after intravenous injection of althesin. 3) Systolic blood pressure was decreased 8mmHg (p<0.01) after one minute of injection and 11 mmHg (p<0.01) after three minutes and raised to preanesthetic level after five minutes. No significant change was found in diastolic blood pressure. 4) Respiratory rate was increased 3/min. (p<0.05) after three minutes. 5) Minute volume was decreased 170Gml (p<0.01) after one minute and 700ml (p<0.05> after three minutes. 6) As complications, involuntary muscle movement of extremities was observed in two cases and transient apnea in one case.
