ReviewPain and inflammatory response following off-pump coronary artery bypass grafting.
Inflammation and pain are two common clinical issues following cardiac surgery, which are important to patient outcomes. This article reviews the literature regarding inflammation and pain following cardiac surgery with special emphasis on off-pump cardiac surgery. ⋯ Off-pump cardiac surgeries although known to decrease the inflammatory burden do not appear to impact the overall patient outcomes. Recent evidence indicates the prothrombotic tendency following off-pump procedures, which could be related to the time course of inflammation following off-pump cardiac surgery. There might be some benefit of off-pump procedures regarding neurological and renal function that needs further studies. Pain management following off-pump procedures is similar to that of patients undergoing on-pump cardiac surgery. Better caregiver and patient education is crucial for improving pain control following cardiac surgery. Analgesic regimens need to consider adjuvants and regional analgesic techniques and patient-controlled modalities while providing care.

Spinal Cord Stimulation Reduces Mechanical Hyperalgesia and Glial Cell Activation in Animals with Neuropathic Pain.
Spinal cord stimulation (SCS) is commonly used for neuropathic pain; the optimal variables and mechanisms of action are unclear. We tested whether modulation of SCS variables improved analgesia in animals with neuropathic pain by comparing 6-hour vs 30-minute duration and 50%, 75%, or 90% motor threshold (MT) intensity (amplitude). Furthermore, we examined whether maximally effective SCS reduced glial activation in the spinal cord in neuropathic animals. ⋯ Six-hour duration SCS with 90% MT showed the largest increase in mechanical withdrawal threshold, suggesting that the variables of stimulation are important for clinical effectiveness. One potential mechanism for SCS may be to reduce glial activation at the level of the spinal cord.

Randomized Controlled Trial Multicenter Study
The analgesic efficiency of combined pregabalin and ketamine for total hip arthroplasty: a randomised, double-blind, controlled study.
Pregabalin and ketamine given together have a small, additive effect in reducing post-operative pain after total hip arthroplasty.

Multicenter StudyEpidural lysis of adhesions for failed back surgery and spinal stenosis: factors associated with treatment outcome.
Failed back surgery syndrome (FBSS) is a challenging problem. One treatment advocated to treat FBSS is epidural lysis of adhesions (LOA). The results of studies examining LOA for FBSS have been mixed, but are limited because no study has ever sought to identify factors associated with outcomes. ⋯ Considering our modest success rate, selecting patients for epidural LOA based on demographic and clinical factors may help better select treatment candidates. Procedural factors such as the use of hyaluronidase that increase risks and costs did not improve outcomes, so further research is needed before these become standard practice.
