Randomized Controlled Trial Clinical TrialEffect of mechanical dilation on nasotracheal intubation.
Various techniques, both chemical and mechanical, have been proposed to decrease trauma and hemorrhage associated with nasotracheal intubation. Nasotracheal intubation was performed on 44 healthy patients scheduled for oral surgical procedures to determine whether incremental dilation with nasopharyngeal airways helps to decrease nasal passage hemorrhage during nasotracheal intubation. ⋯ Repeated passage of the nasopharyngeal airway and nasotracheal tube over relatively friable nasal mucosa accounted for increased hemorrhage in the dilated group. For routine nasotracheal intubation of healthy patients, dilation with nasopharyngeal airways needlessly adds time, trauma, and hemorrhage to the induction of anesthesia.

Case ReportsParalysis of the hemidiaphragm as a complication of internal jugular vein cannulation: report of a case.
A case of phrenic nerve injury following cannulation of the internal jugular vein is presented. Considering the close relation between the phrenic nerve and the internal jugular vein, one should be aware of the possibility of phrenic nerve injury with an increase in the number of attempts at cannulation.
