Randomized Controlled Trial
The use of an online three-dimensional model improves performance in ultrasound scanning of the spine: a randomized trial.
The use of ultrasound for neuraxial blockade is a new application of technology that is rapidly becoming accepted as a standard of care. This new skill has shown to improve success, but it is a challenge to teach. To assist with teaching the use of ultrasound in regional anesthesia of the lumbar spine, we have developed an interactive educational model ( http://pie.med.utoronto.ca/vspine or http://www.usra.ca/vspine.php ). In this study, we aimed to determine whether use of this model for a two-week period would improve the performance of novice operators in determining defined landmarks during real-time ultrasound imaging of the lumbar spine. ⋯ Our results show superior performance by the residents who had access to both components of the module, indicating that access to the interactive ultrasound spine module improves knowledge and skills prior to clinical care.

Randomized Controlled Trial
Gabapentin does not improve multimodal analgesia outcomes for total knee arthroplasty: a randomized controlled trial.
This study assessed whether gabapentin given preoperatively and for two days postoperatively (in addition to patient-controlled analgesia [PCA] morphine, acetaminophen, and ketorolac) is effective in reducing morphine requirements and moderating pain scores when compared with placebo for primary total knee arthroplasty. ⋯ Gabapentin 600 mg po given preoperatively followed by 200 mg po every eight hours for two days has no effect on postoperative morphine consumption, pain scores, patient satisfaction, or length of hospital stay. This trial is registered at ClinicalTrials.gov NCT01307202.

Randomized Controlled Trial
Gabapentin reduces preoperative anxiety and pain catastrophizing in highly anxious patients prior to major surgery: a blinded randomized placebo-controlled trial.
Gabapentin is increasingly being used for the treatment of postoperative pain and a variety of psychiatric diseases, including chronic anxiety disorders. Trials have reported mixed results when gabapentin has been administered for the treatment of preoperative anxiety. We tested the hypothesis that gabapentin 1,200 mg vs placebo would reduce preoperative anxiety in patients who exhibit moderate to high preoperative anxiety. ⋯ Administration of gabapentin 1,200 mg prior to surgery reduces preoperative NRS anxiety scores and pain catastrophizing scores and increases sedation prior to entering the operating room. These results suggest that gabapentin 1,200 mg may be a treatment option for patients who exhibit high levels of preoperative anxiety and pain catastrophizing; however, the sedative properties of the medication and the possibility of delayed postoperative discharge in the elective ambulatory population need to be considered.
