Randomized Controlled TrialMannitol Improves Intraoperative Brain Relaxation in Patients With a Midline Shift Undergoing Supratentorial Tumor Surgery: A Randomized Controlled Trial.
Mannitol is widely used to reduce brain tissue swelling and improve brain relaxation during neurosurgery. However, the optimal dosage for patients with midline shift undergoing supratentorial tumor resection remains unclear. ⋯ An optimal mannitol infusion dosage of 1.0 g/kg is recommended to improve brain relaxation with lower risk of moderate to severe postoperative cerebral edema in patients with midline shift undergoing supratentorial tumor resections. The effect of mannitol on brain relaxation is affected by tumor size and severity of peritumoral edema, rather than by midline shift.

Randomized Controlled TrialThe Effect of Depth of Anesthesia on Hemodynamic Changes Induced by Therapeutic Compression of the Trigeminal Ganglion.
Percutaneous compression of the trigeminal ganglion (PCTG) has been used to treat trigeminal neuralgia since 1983. A PCTG-related trigeminocardiac reflex (TCR) can induce dramatic hemodynamic disturbances. This study investigates the effects of depth of propofol anesthesia on hemodynamic changes during PCTG. ⋯ Increasing the depth of propofol anesthesia partially attenuated PTCG-related elevation of blood pressure but did not modify the abrupt reduction in HR.

Randomized Controlled TrialBilateral Ultrasound-guided Erector Spinae Plane Block for Postoperative Analgesia in Lumbar Spine Surgery: A Randomized Control Trial.
Major lumbar spine surgery causes severe postoperative pain. The primary objective of this randomized controlled study was to compare the effect of ultrasound (US)-guided erector spinae plane (ESP) block on 24-hour postoperative cumulative opioid requirements with standard (opioid-based) analgesia. Postoperative pain control and patient satisfaction were also assessed. ⋯ US-guided ESP block reduces postoperative opioid requirement and improves patient satisfaction compared with standard analgesia in lumbar spine surgery patients.
