误吸指进食或非进食时吞咽过程中有数量不一的液体或固体食物(包括分泌物或血液等)进入到声门以下的气道,而不是象通常一样的全部食团随着吞咽动作顺利地进入到食管[1]。吞咽是一系列复杂的神经肌肉运动过程,受大脑支配,需口、咽、食管共同参与,其中任何一个部位的机能障碍均可导致误吸[2]。我科收治的多数为老年晚期肿瘤患者,老年人由于 相似文献

Swallows of 4 bolus volumes (1, 5, 10, 20 ml) were examined in three groups of subjects: 6 subjects 20–29 years of age, 12
subjects 30–59 years of age, and 6 subjects 60–79 years of age. A simultaneous manometric and videofluoroscopic data collection
protocol permitted measurement of bolus transit, temporal aspects of the oropharyngeal swallow, and pharyngeal peristalsis.
Statistically significant effects of increasing bolus volume were oral transit of the bolus head (decreased) and duration
of cricopharyngeal opening (increased). Five measures were significantly changed with increasing age: duration of pharyngeal
swallow delay (increased), duration of pharyngeal swallow response (decreased), duration of cricopharyngeal opening (decreased),
peristaltic amplitude (decreased), and peristaltic velocity (decreased). 相似文献

Outside of the otolaryngologic literature it is not generally recognized that symptoms of gastroesophageal reflux are associated
with abnormalities in the larynx and pharynx. Published data of videorecordings of the normal pharyngeal swallow in 16 patients
asymptomatic for dysphagia or gastroesophageal reflux were compared to data from recordings from a second group of 70 patients,
who were symptomatic for dysphagia or gastroesophageal reflux. Both groups were timed in a similar manner, and the timing
data were compared by Studentt-test to determine if functional variations between the groups existed. Fifty-eight timed events occurring during the swallowing
process, 23 in the anterior view and 35 in the lateral view, were analyzed.
A comparison of events occurring before and after bolus arrival in the esophagus was made. Eighteen percent of events in the
pre-esophageal period occurred significantly earlier (p<0.05) in the symptomatic group. Marked differences were seen after the bolus entered the esophagus as 39% of events occurred
significantly later in the symptomatic group. Our data suggest that individuals with symptoms of gastroesophageal reflux disease
demonstrate a number of functional variations during the pharyngeal swallow. This finding is consistent with structural changes
described in the otolaryngologic literature.

The electrophysiological features of voluntarily induced and reflexive/spontaneous swallows were investigated. In normal
subjects, swallows were elicited by infusing water either into the mouth (1–3 ml) or directly into the oropharyngeal region
through a nasopharyngeal cannula (0.3–1 ml). For water infused orally, subjects were either requested to swallow voluntarily
or instructed to resist swallowing and maintain the horizontal head position until swallowing occurred reflexively. Spontaneous
saliva swallowing was investigated in patients with severe dysphagia who had a prominent clinical picture of suprabulbar palsy.
Comparisons between different swallowing types were made by measuring the time interval between the onset of submental electromyographic
activity (SM-EMG) and the onset of the upward movement of the larynx recorded by a movement sensor. This interval was less
than 100 ms, even frequently less than 50 ms, in reflexive/spontaneous swallows, while in voluntarily induced swallows it
was substantially longer. The rising time of submental muscle's excitation was also shorter in reflexive/spontaneous swallows.
It was suggested that the triggering of voluntarily induced swallows commences more than 100 ms before the onset of swallowing
reflex and that this mechanism is under the control of corticobulbar–pyramidal pathways. If the swallowing reflex is triggered
within such a short period of time following the onset of SM-EMG, the central control by the bulbar swallowing center should
be effective until the end of oropharyngeal swallowing. 相似文献

Objective: To explore the hypothesis that better health status of elderly populations is primarily determined by the provision of freely accessible health service at low or no cost to the user and a social welfare system. Method: Information was collected by questionnaire from surveys of three cohorts of elderly (70 years and older) Chinese. Data from two health‐care systems were compared: the low‐cost or free government‐subsidised system in Hong Kong, and the market‐orientated user‐pays system in urban (Beijing), and rural China. Results: The Beijing rural cohort had the best health profile, whereas the Hong Kong cohort had the worst, despite the better lifestyle practices in the Hong Kong and Beijing urban cohorts compared with the Beijing rural cohort, and higher socioeconomic status in the Beijing urban and Hong Kong cohorts. However, the Beijing rural cohort had the highest prevalence of functional limitations. Conclusion: While health‐care systems may affect life expectancy at birth, psychosocial, lifestyle and socioeconomic factors influence subsequent health status of elderly people in a complex manner. 相似文献

Oropharyngeal aspiration and pneumonia in children 总被引:1,自引:0,他引:1
Oropharyngeal aspiration (OPA) of food and fluids is known to be associated with pneumonia in dysphagic children with neurological disease and direct causality is often assumed. However, little is known about the relationship between OPA and pneumonia in medically complex children when other possible risk factors for pneumonia are considered. We examined the association of World Health Organization (WHO)-defined pneumonia in a heterogeneous group of children with swallowing dysfunction identified by a videofluoroscopic swallow study (VFSS). A retrospective chart review of 150 children (aged 2 weeks to 20 years) was undertaken to determine the relationship between pneumonia and (i) type of swallowing dysfunction (including OPA), (ii) consistency of aspirated food/fluid, and (iii) other factors including multisystem involvement and age (1 year). In univariate analysis, the odds ratio (OR) for pneumonia was significantly increased in children with post-swallow residue (PSR) (OR 2.5) or aspiration on thin fluids (OR 2.4), but not with aspiration of thick fluids or purees. In multi-logistic regression, type of swallowing dysfunction or aspirated food/fluid were no longer significant. Instead, pneumonia was significantly associated with diagnosis of asthma (OR 13.25), Down syndrome (OR 22.10), gastroesophageal reflux disease (GERD) (OR 4.28), or history of LRTI (OR 8.28), moist cough (OR 9.17) or oxygen supplementation (OR 6.19). Children with multisystem involvement demonstrated a higher association with pneumonia, but no difference was found for age. We conclude that the impact of OPA on development of pneumonia is considerably reduced once other factors in children with multisystem involvement are taken into account. 相似文献

Numerous articles on the topic of neurologic, cardiac, and burn complications following electrical injury have appeared in
the literature since 1934 [1]. Specific mention of dysphagia as a complication of survivors of this type of injury was not
found on literature review. For this reason our case is of particular interest. This patient presented with a primary deficit
of severe dysphagia following medical stabilization after lightning strike. A structured series of diagnostic and treatment
programs was implemented, which included serial modified barium swallows (or “cookie” swallows [2]), thermal stimulation,
oral motor exercises, and laryngeal adduction tasks. The patient improved over 1 month from a nonoral intake status to a regular
diet while habitually using a learned swallowing technique. 相似文献
