Laryngeal function is vital to airway protection. While swallow is mediated by the brainstem, mechanisms underlying increased risk of dysphagia after cervical spinal cord injury (SCI) are unknown. We hypothesized that loss of descending phrenic drive affects swallow and breathing differently, and loss of ascending spinal afferent information alters...

Opioid use is associated with increased risk of chest infection due to opioid suppression of immune function, ventilation, cough, and secretion mobilization. Buprenorphine is a highly lipophilic, semi-synthetic partial agonist of the mu opioid receptor. Intramuscular buprenorphine is commonly used for post-operative analgesia at a dose range of 0.0...

Swallow is a critical behavior for sustaining life, important for both for the ingestion of nutrients and for protecting the airways. To produce an effective swallow, neural circuits must coordinate over 20 muscles across multiple cranial/spinal nerves to produce a rostral-caudal pressure gradient to move the bolus from the mouth to the stomach. Th...
Article
Airway protection is maintained through a constellation of behaviors. The laryngeal adductor reflex (LAR) responds to mechanical or chemical stimulation of the laryngeal orifice with rapid adduction of the vocal folds. While there are abundant serotonin receptors on laryngeal motoneurons, the effects of serotonin agents on the LAR have not been inv...

Proper function of the larynx is vital to airway protection, including swallow. While the swallow reflex is controlled by the brainstem, patients with cervical spinal cord injuries (cSCI) are likely at increased risk of disordered swallow (dysphagia) and pneumonia, and the underlying mechanisms are unknown. We aimed to determine if acute spinal cor...
