Airway problems related to laryngeal mask airway use associated with an undiagnosed epiglottic cyst.

This report describes airway management difficulties in a patient with an asymptomatic and undiagnosed epiglottic cyst. Mask ventilation after induction of general anesthesia was uneventful. Insertion of an LMA resulted in inadequate ventilation. Fiberoptic intubation through an intubating LMA was impossible because the LMA pushed the cyst into the laryngeal inlet. Fibreoptic intubation, assisted by the use of a direct laryngoscope without the LMA was uneventful. Preoperative craniocervical scans performed for assessment of other conditions may reveal asymptomatic pathology in the airway.

Quantitation of nucleotides, nucleosides and bases in antemortem and postmortem bloodstains by high-performance liquid chromatography.

Ante- and post-mortem bloodstains prepared from the blood of volunteers and corpses were analysed for ATP and its related compounds by reversed-phase high-performance liquid chromatography (HPLC). The results showed that (1) ATP was present in a large amount in antemortem bloodstains but not in postmortem stains, (2) AMP, adenosine, inosine, hypoxanthine, xanthine and uracil either were not detected or were detected in smaller amounts in antemortem than in postmortem bloodstains, and (3) ADP was present in both ante- and post-mortem bloodstains. These differences suggest that quantitation of these compounds may be useful in identifying whether bloodstains are ante- or post-mortem.

Re-evaluation of death by asphyxia based on cerebral blood flow (VII)--on the information on electric potentials obtained from deep electroencephalographic electrodes.

The author presents electroencephalographic patterns (a physiological parameter of the brain function observed at rapid and fatal drowning of rabbits), cerebral blood flow (CBF) which support the physiological activities of the brain, and the relationship between systemic respiration and circulation with special reference to changes in the electrical potentials detected by deep electroencephalographic electrodes. The possibility of diagnosis of fatal drowning is examined, based on the results.

Cerebral blood flow and serum haptoglobin in the diagnosis of death by rapid drowning.

Diagnosis of death and the feasibility of resuscitation in cases of acute drowning in fresh water (FW) or sea water (SW) inhalation in rabbits were evaluated using cardiopulmonary function monitoring, measurement of cerebral blood flow (CBF) and determination of haptoglobin (HP). Death took place more quickly in FW drowning, two to five minutes, as compared with four to seven minutes required in SW drowning. In view of the CBF patterns in the brain circulation, many problems exist regarding the judgement of the point of death and the applicability of resuscitation. However, it is considered that brain damage in SW drowning occurs more rapidly than in FW drowning.
