Randomized Controlled Trial
Hemodynamic characteristics of midazolam, propofol, and dexmedetomidine in healthy volunteers.
To study the effect of intravenous (IV) sedation on blood pressure (BP), heart rate (HR), and respiratory rates (RR) to determine if IV sedatives differ with respect to their effect on BP, HR, and RR. ⋯ When administered in sedative doses, dexmedetomidine and, to a lesser extent, midazolam, reduces BP in a dose-dependent fashion. Dexmedetomidine also reduces HR. Midazolam does not affect BP or HR.

Randomized Controlled Trial Comparative Study
Comparison of volume-controlled and pressure-controlled ventilation in steep Trendelenburg position for robot-assisted laparoscopic radical prostatectomy.
To compare the effects of volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) on respiratory mechanics and hemodynamics in steep Trendelenburg position. ⋯ PCV offered greater C(dyn) and lower AP(peak) than VCV, but no advantages over VCV in respiratory mechanics or hemodynamics.

Meta Analysis
Capnography enhances surveillance of respiratory events during procedural sedation: a meta-analysis.
To determine if capnography, in addition to standard monitoring, identified more respiratory complications than standard monitoring alone. ⋯ End-tidal carbon dioxide monitoring is an important addition in detecting respiratory depression during PSA.

Subarachnoid hemorrhage is associated with a number of cerebral insults as a result of cerebral vasospasm. Various pharmacological and non-pharmacological techniques are used for relief of cerebral vasospasm. ⋯ The case of a patient with an anterior communicating artery aneurysm, who received intracisternal papaverine by instillation after aneurysm clipping, is reported. It was associated with hypertension and tachycardia that was not responsive to usual treatment.

Randomized Controlled Trial
The effect of nitrous oxide on intracuff pressure of the size 2 ProSeal Laryngeal Mask Airway.
To investigate intracuff pressure changes in the ProSeal Laryngeal Mask Airway (PLMA) during 50% nitrous oxide (N₂O) anesthesia. ⋯ PLMA intracuff pressure increased significantly during 50% N₂O anesthesia. The children's postoperative throat complication rate also was increased.
