While the majority of studies examining preoperative risk have acknowledged that hypercarbia represents a relative contraindication to lung resection, a threshold value of 45 mm Hg has not been formally evaluated.3 Most studies have not listed PaCO2 values, although it is likely the major...
متن کاملPhrenic Nerve Pacing: Current Concepts
Anatomy: The diaphragm is the main inspiratory muscle in mammals, it is a highly active muscle with a duty cycle of 30-40%, and therefore, the diaphragm may be particularly susceptible to inactivity or disuse (1). It is innervated by the phrenic nerves that arise from the nerve roots C3 through C5, and is primarily composed of fatigue-resistant slow-twitch type I and fast-twitch IIa myofibers. ...

متن کاملSchwannoma of the accessory phrenic nerve.
Otolaryngologists are frequently confronted with the management of cervical tumors. Neurogenic tumors concern, especially, the cranial, sympathetic, or peripheral nerve sheathes. These tumors are benign and grow slowly. The involvement of the cervical part of the phrenic nerve is exceptional, and only 2 cases are reported in the literature. We describe the first case of a cervical schwannoma in...
متن کاملCervical variations of the phrenic nerve.
OBJECTIVES/HYPOTHESIS Selective reinnervation of the posterior cricoarytenoid muscle with a single phrenic nerve rootlet has been shown to restore physiologic motion in animal models. However, clinical translation of this work is challenged by the limited knowledge of the cervical anatomy of the phrenic nerve. STUDY DESIGN Prospective collaborative study. METHODS Dissection of 111 cadaveric...
