Randomized Controlled TrialUltrasound-Guided Pecto-Intercostal Fascial Block for Postoperative Pain Management in Cardiac Surgery: A Prospective, Randomized, Placebo-Controlled Trial.
To explore the effect of pecto-intercostal fascial plane block (PIFB) on postoperative opioid requirements, pain scores, lengths of intensive care unit and hospital stays and incidence of postoperative delirium in cardiac surgical patients. ⋯ Patients who received PIFB with bupivacaine showed a decline in cumulative opioid consumption postoperatively, but this difference between the groups was not statistically significant. Low incidence of complications and improvement in visual analog scale pain scores suggested that the PIFB can be performed safely in this population and warrants additional studies with a larger sample size.

Aim: Low back pain is a leading cause of patient disability in the USA. Our goal was to determine association between patient characteristics and their response to lumbar medial branch block, radiofrequency ablation of medial nerves or lumbar facet joint injections. ⋯ Results: At the 3-month post-procedure visit, positive responders were significantly more likely to be non obese patients (BMI <30) and those with pain <5-years. Conclusion: Obesity and chronicity of pain certainly are found to be predictors of response to the above mentioned procedures.

Does the presence of cranial contrast spread during a sacroiliac joint injection predict short-term outcome?
The innervation of the sacroiliac joint (SIJ) is complex, with a dual innervation originating from the lumbosacral plexus anteriorly as well as the sacral lateral branches posteriorly. Nociceptors are found in intra-articular structures as well as periarticular structures. In patients with SIJ pain, a fluoroscopy-guided SIJ injection is usually performed posteriorly into the bottom one-third of the joint with local anesthetic and corticosteroids, but this does not always reach all intra-articular structures. The correlation between a cranial contrast spread and clinical success is undetermined in patients with SIJ pain. ⋯ In patients with SIJ pain, identified by positive pain provocation maneuvers, cranial contrast spread as a marker of intra-articular injection, with subsequent injection of 3 mL of local anesthetic and methylprednisolone 40 mg, was significantly correlated with clinical success up to 4 weeks. Therefore, attempts should be made to reach this final needle position before injecting local anesthetic and corticosteroids. This result needs to be confirmed in a high-quality prospective trial.
