摘要:

The sympathetic response to rigid bronchoscopy, laryngoscopy and esophagoscopy, performed under general anesthesia with isoflurane, was examined in patients who either received 5 ml of 2 % lidocaine (n = 7) or 5 ml of saline (n = 7), sprayed on larynx and upper trachea under direct laryngoscopy, 2 min before the introduction of the rigid bronchoscope. Blood pressure, heart rate and plasma catecholamine and lidocaine levels were measured at specific time points of the study. Topical lidocaine led to a rapid and prolonged increase in plasma lidocaine levels. Patients treated with lidocaine showed a small but significant decrease in plasma epinephrine levels from baseline following endotracheal intubation and extubation, as compared to the saline control group. Blood pressure and heart rate response during rigid panendoscopy, isoflurane requirements and time interval from termination of panendoscopy to extubation were not different between the two groups. However, in contrast to the control group, patients who had received lidocaine had no significant rise in blood pressure and heart rate from baseline following the introduction of the rigid bronchoscope. The benefit of this moderate hemodynamic stabilizing effect of lidocaine has to be weighed against the risk of decreased protective airway reflexes due to topical laryngeal lidocaine during recovery from anesthesia.

摘要:

Heterotopic brain tissue is an unusual substance which is very difficult to diagnose correctly preoperatively. We report on a 7-month-old male infant with heterotopic brain tissue of the soft palate, and describe the results of preoperative examinations including brain scintigraphy, angiography, brain computed tomography and magnetic resonance imaging (MRI). MRI was found useful to show that the tumor had no junction with the intracranial space. The patient was treated successfully without complication or recurrence after 1.5 years follow-up.

摘要:

A review of the 20th century English-language literature has produced a total of 320 cases of tuberculous otitis media or otomastoiditis, of which a surprising 93 cases have been reported in the 5-year period 1986–1990. Eighty-three percent of these have come from indigenous African populations. The international health and sociological implications of this development are disturbing. Three personal cases seen during the past 8 years are presented, all of whom came from the indigenous Norwegian population. The epidemiology of these cases is therefore different, which can result in a diagnostic delay due to a low index of suspicion. The historically classical signs of this disease are frequently absen
