Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Nasal versus oral fiberoptic intubation via a cuffed oropharyngeal airway (COPA) during spontaneous ventilation.
To compare the success rate of nasal versus oral fiberoptic intubation in anesthetized patients breathing spontaneously via the cuffed oropharyngeal airway (COPAtrade mark). ⋯ Nasal fiberoptic laryngoscopy is more successful and easy than the oral approach in anesthetized patients who are breathing spontaneously through the COPA.

Randomized Controlled Trial Comparative Study Clinical Trial
Surgery on the affected upper extremity of patients with a history of complex regional pain syndrome: the use of intravenous regional anesthesia with clonidine.
To evaluate the efficacy of intravenous regional anesthesia (IVRA) with clonidine in patients with a previous history of complex regional pain syndrome (CRPS) who are undergoing upper extremity hand surgery. ⋯ Intraoperative IVRA with lidocaine and clonidine on patients with a history of CRPS can significantly reduce the recurrence rate of this disease process.

Randomized Controlled Trial Clinical Trial
Prophylactic nebulized lidocaine attenuates hyperdynamic response to abrupt mask inhalation of isoflurane in adults.
To examine whether prophylactic, atomized lidocaine blunts hyperdynamic responses and catecholamine release after an abrupt increase in volatile anesthetic administration. ⋯ Prophylactic ultrasonically nebulized lidocaine (2 mg/kg) obtunds the hyperdynamic responses to abrupt inhalation of 5% isoflurane but does not completely block catecholamine release.

Case Reports
Variable systolic pressure variation and dynamic hyperinflation due to an intrabronchial tumor.
Systolic pressure variation (SPV) is the cyclic change in systolic blood pressure secondary to positive-pressure ventilation. It is normally a good indicator of intravascular volume and often can be substituted for central venous pressure monitoring, but the reliability of SPV for this use depends on the multiple determinants of intrathoracic pressure remaining constant. ⋯ This situation, in turn, caused a marked increase in SPV but, more importantly, it increased variability of the SPV despite normal intravascular volume. We discuss the physiology of SPV and the implications of this case for the use of SPV as a monitor of intravascular volume.

We present a case of postoperative delirium following endoscopic sinus surgery. We postulate a mechanism for this rare event.
