Randomized Controlled Trial
Effect of Ondansetron on post-operative shivering after craniotomy.
Postoperative shivering (POS) is an early complication after craniotomy. Preventive pharmacologic drugs are the mainstay of treatment. Meperidine is the drug of choice but with increased risk of apnea, nausea, and increased intracranial pressure. Some reports have suggested that ondansetron and meperidine have similar anti-shivering effects. ⋯ Ondansetron can effectively decrease POS after craniotomy. This effect is not mediated through maintenance of the core or peripheral temperature. Ondansetron probably acts by a central inhibitory mechanism on POS through 5-hydroxytryptaminergic pathways, not by changing thermoregulatory set points.

Review Meta Analysis Comparative Study
Hybrid Decompression Technique versus Anterior Cervical Corpectomy and Fusion for Treating Multilevel Cervical Spondylotic Myelopathy: Which One Is Better?
The hybrid decompression technique (corpectomy combined with discectomy) and anterior cervical corpectomy with fusion (ACCF) both provide good neurological recovery and disease stabilization for the treatment of multilevel cervical spondylotic myelopathy (CSM). However, no single study has been large enough to determine definitively which one is superior for this condition. ⋯ Based on this meta-analysis, both the hybrid technique and ACCF can achieve good results for CSM. However, the hybrid technique is associated with significantly less blood loss, complications, and a higher fusion rate than ACCF.

Review Meta Analysis
Postoperative Visual Loss Following Lumbar Spine Surgery: A Review of Risk Factors by Diagnosis.
Postoperative visual loss (POVL) is a potentially devastating complication of lumbar spine surgery that may lead to significant functional impairment. Although POVL is rare, a review of the literature shows that it is being reported with increasing frequency. A systematic analysis detailing the etiology and prognosis of the 3 main types of POVL has yet to be published. We reviewed potential preoperative and intraoperative risk factors for ischemic optic neuropathy (ION), central retinal artery occlusion (CRAO), and cortical blindness (CB) after lumbar spine surgery. ⋯ We reviewed the preoperative and intraoperative risk factors for each of the 3 main POVL types, using several published case reports to supplement the limited large-scale studies available. ION risks may be influenced by a longer operative time in the prone position with anemia, hypotension, and blood transfusion. The risk for CRAO is usually due to improper positioning during the surgery. Prone positioning and obesity were found to be most commonly associated with CB development. The prognosis, prevention techniques, and treatment of each POVL type can vary considerably.
