To examine the safety and efficacy of pre-operative embolization of intra-and extracranial tumors and determine the selection criteria of patients for this procedure. ⋯ Although pre-operative embolization of intra- and extracranial tumors was safe, only extensive or complete angiographic devascularization has been effective in less intra-operative blood loss. From this present study, indications regarding when to perform pre-operative embolization include history of excessive bleeding from previous surgery, known hypervascular tumor types (e.g., hemangiopericytoma, hemangioblastoma, paraganglioma), the presence of multiple flow voids on MRI, hypervascular tumors of skull or scalp, deep-seated tumors (e.g., cranial base tumor, intraventricular tumor) with difficulty in early surgical access of the main feeding vessels, and tumors associated with intratumoral aneurysm.

Randomized Controlled Trial Comparative Study
Comparing the Success Rate of Radial Artery Cannulation under Ultrasound Guidance and Palpation Technique in Adults.
Previous studies have shown ultrasound guidance (USG)for arterial cannulation being advantageous compared to palpation technique, but little is known about its performance by novices. ⋯ Regarding success rate, attended time, or number of attempts for radial arterial cannulation, we did not find any benefit of ultrasound guidance compared to palpation technique. Our findings were not in accordance to other trials. However, we have to consider operators in our study being in experienced in ultrasound-guided procedures but not in palpation techniques.

Randomized Controlled Trial
Onset Time of 2% Lidocaine and 0.5% Bupivacaine Mixture versus 0.5% Bupivacaine Alone using Ultrasound and Double Nerve Stimulation for Infraclavicular Brachial Plexus Anesthesia in ESRD Patients Undergoing Arteriovenous Fistula Creation.
To reduce the onset of 0.5% bupivacaine by adding 2% lidocaine with 0.5% bupivacaine for ultrasound-guided and double stimulation technique at musculocutaneous and radial nerve for infraclavicular brachial plexus block. ⋯ Mixing 2% lidocaine with 0.5% bupivacaine to the final concentration of 0.67%for lidocaine and 0.33% for bupivacaine does not reduce the onset of ultrasound-guided infraclavicular brachial plexus block.

Randomized Controlled Trial
The Efficacy of Two Oxygen Therapy Devices (Nasal Cannula vs. Simple Mask) for Preventing Hypoxemia after General Anesthesia: A Randomized Controlled Non-Inferiority Trial of 500 Patients.
To compare the efficacy of two oxygen devices (nasal cannula and mask) and two flows for preventing hypoxemia in post anesthesia care unit (PACU). ⋯ In low risk patients undergoing low risk operations, both nasal cannula or simple mask with FiO₂ = 0.35 are equally effective for preventing hypoxemia in PACU.

Posterior cranial fossa surgery is commonly performed under sitting and horizontal position in our institution. Venous air embolism is a potentially serious complication of neurosurgery especially in the sitting position. ⋯ The incidence of severe venous air embolism detected by end tidal CO₂ was significantly higher in SP group. However, 11% of HP group were suspected of severe air embolism.
