Lateral lumbar interbody fusion for the correction of spondylolisthesis and adult degenerative scoliosis in high-risk patients: early radiographic results and complications.
Lateral lumbar interbody fusion (LLIF) is not associated with many of the complications seen in other interbody fusion techniques. This study used computed tomography (CT) scans, the radiographic gold standard, to assess interbody fusion rates achieved utilizing the LLIF technique in high-risk patients. ⋯ Several studies have evaluated LLIF fusion and reported fusion rates between 88%-96%. Our results demonstrate high fusion rates using this technique, despite multiple comorbidities in the patient population. Spanning the ring apophysis with large LLIF cages along with supplemental posterior pedicle screw augmentation can enhance stability of the fusion segment and increase fusion rates.

ReviewClinical decision support alert appropriateness: a review and proposal for improvement.
Many healthcare providers are adopting clinical decision support (CDS) systems to improve patient safety and meet meaningful use requirements. Computerized alerts that prompt clinicians about drug-allergy, drug-drug, and drug-disease warnings or provide dosing guidance are most commonly implemented. Alert overrides, which occur when clinicians do not follow the guidance presented by the alert, can hinder improved patient outcomes. ⋯ The proposed research introduces several innovations to address the challenges and gaps in alert evaluations. This research can transform alert evaluation processes across healthcare settings, leading to improved CDS, reduced alert fatigue, and increased patient safety.

Postoperative vision loss after spine surgery: a single-institution case-control comparison.
Postoperative vision loss (POVL) after spine surgery is a rare but devastating outcome. We present the first case-control study from a single institution for POVL with the diagnoses of ischemic optic neuropathy or central vision loss after complex spine surgery. ⋯ We found that patients with POVL had significantly greater blood loss and significantly more red blood cell transfusions than their matched controls.

ReviewFuture management of carotid stenosis: role of urgent carotid interventions in the acutely symptomatic carotid patient and best medical therapy for asymptomatic carotid disease.
Stroke is the fourth leading cause of death in the United States, leading to devastating disability. Most strokes are ischemic, and nearly one-third of these are caused by carotid disease. The primary mechanism of carotid-related stroke is an atheroembolic event from an unstable atherosclerotic plaque rupture. In the 1990s, randomized trials demonstrated the benefit of carotid endarterectomy (CEA) in reducing the risk of stroke in both symptomatic and asymptomatic carotid disease. ⋯ CAS has an increasingly higher risk of stroke with advancing age. Patients treated with CAS have a 1.76-fold increased risk of stroke (95% CI, 1.35-2.31) with each 10-year increase in age. No such age effect is seen in patients treated with CEA. Age is a critical variable in making informed choices regarding treatment of severe carotid artery stenosis.

Ultrasound imaging for endotracheal tube repositioning during percutaneous tracheostomy in a cadaver model: a potential teaching modality.
Percutaneous tracheostomy (PCT) is a widely accepted method for the insertion of a tracheostomy tube in a critically ill patient. Because a patient's preexisting endotracheal tube is manipulated during the procedure, premature extubation with potential catastrophic loss of airway control is a risk. As portable ultrasound imaging becomes increasingly useful in the critical care setting, investigations continue to determine the safety of PCT with the technology. ⋯ Ultrasound can be used to identify an endotracheal tube cuff during a PCT, and repositioning the endotracheal tube under ultrasound guidance could decrease the risk of accidental extubation. This approach to PCT may be used in a cadaveric model to teach anatomy and procedural skills to learners and possibly further adopted in real patients to improve the overall safety profile of the PCT procedure.
