Randomized Controlled Trial
Effect of the degree of reverse Trendelenburg position on intraocular pressure during prone spine surgery: a randomized controlled trial.
Postoperative vision loss complicates an estimated 1 in 1,100 prone spine surgical cases. This complication has been attributed to ischemic optic neuropathy, with one proposed reason being perioperative elevations in intraocular pressure (IOP). Previous research has studied the effects of table inclination on IOP in awake volunteers; however, the effects in spine surgery patients have not been investigated for reverse Trendelenburg positioning using a prospective, randomized controlled study design. ⋯ Reverse Trendelenburg positioning elicits decreased IOP compared with prone positioning for surgery times less than 120 minutes. Ten degrees of reverse Trendelenburg attenuate the rise in IOP during prone spine surgery superiorly in comparison with 5°. No significant complications were associated with reverse Trendelenburg positioning.

Randomized Controlled Trial
Spinal manipulative therapy and exercise for seniors with chronic neck pain.
Neck pain, common among the elderly population, has considerable implications on health and quality of life. Evidence supports the use of spinal manipulative therapy (SMT) and exercise to treat neck pain; however, no studies to date have evaluated the effectiveness of these therapies specifically in seniors. ⋯ SMT with HE resulted in greater pain reduction after 12 weeks of treatment compared with both supervised plus HE and HE alone. Supervised exercise sessions added little benefit to the HE-alone program.

Randomized Controlled Trial
Microwave diathermy for treating nonspecific chronic neck pain: a randomized controlled trial.
Although the use of deep heat therapy is widespread, there is scant literature available on its effectiveness in treating back or neck pain. ⋯ Microwave diathermy does not provide additional benefit to a treatment regimen of chronic neck pain that already involves other treatment approaches.

Randomized Controlled Trial
Intraoperative systemic infusion of lidocaine reduces postoperative pain after lumbar surgery: a double-blinded, randomized, placebo-controlled clinical trial.
Analgesic effect of lidocaine infusion on postoperative pain. ⋯ Intraoperative systemic infusion of lidocaine decreases pain perception during microdiscectomy, thus reducing the consumption of opioid and the severity of postoperative pain. This effect contributes to reduce the length of HS.

Randomized Controlled Trial
The effect of milrinone on induced hypotension in elderly patients during spinal surgery: a randomized controlled trial.
Induced hypotension is widely used intraoperatively to reduce blood loss and to improve the surgical field during spinal surgery. ⋯ We conclude that milrinone is useful for induced hypotension in elderly patients during spinal surgery.
