Randomized Controlled Trial Comparative Study Retracted Publication
Effects of bilateral Pecto-intercostal Fascial Block for perioperative pain management in patients undergoing open cardiac surgery: a prospective randomized study.
Open cardiac surgical patients may experience severe acute poststernotomy pain. The ultrasound-guided Pecto-intercostal Fascial Block (PIFB) can cover anterior branches of intercostal nerves from T2 to T6. The aim of this study was to investigate the effect of bilateral PIFB in patients undergoing open cardiac surgery. ⋯ Bilateral PIFB provides effective analgesia and accelerates recovery in patients undergoing open cardiac surgery.

Randomized Controlled Trial
Decreasing leakage during continuous femoral nerve catheter fixation using 2-octyl cyanoacrylate glue (Dermabond®): a randomized controlled trial.
Continuous peripheral nerve catheters (CPNCs) have been used for postoperative pain relief. A common problem encountered with CPNCs is pericatheter leakage, which can lead to dressing adhesive failure. Frequent dressing changes increase the risk of catheter dislodgement and infections. Adhesive glue is effective in securing the peripheral nerve catheter and decreasing leakage around the catheter insertion site. This study aimed to evaluate the incidence of pericatheter leakage with fixation using 2-octyl cyanoacrylate glue (Dermabond®) as compared to sterile strips. ⋯ Catheter fixation with 2-octyl cyanoacrylate glue (Dermabond®) decreased the incidence of pericatheter leakage, as well as catheter displacement, over 48 h as compared to sterile strip fixation.

Observational Study
Infrared thermography for assessment of thoracic paravertebral block: a prospective observational study.
There was no "gold standard" to assess the success or failure of thoracic paravertebral block (TPVB). Measurement of skin temperature with infrared thermography (IT) would be a reliable method to evaluate the effectiveness of regional blocks. This study aimed to explore the feasibility of using skin temperature difference (Td) determined by IT between the blocked and unblocked side to predict the spread of TPVB. ⋯ This study suggested that the increase of Td at T4 dermatome determined by IT between the blocked and unblocked side is an early, quantitative, and reliable predictor of successful TPVB.

Efficient pain management is essential for postoperative rehabilitation in patients undergoing a tumor resection with an immediate reconstructive surgery. Ultrasound-guided quadratus lumborum block has been described for abdominal or hip surgery, but not for concomitant surgery in the abdomen and the thigh. The paraspinous transmuscular approach has easy landmarks to perform this block. We present a case of a patient undergoing a resection of a sarcoma in the lower limb with an immediate reconstruction with a pedicled vertical designed deep inferior epigastric perforator flap, in whom a successful paraspinous transmuscular quadratus lumborum block for postoperative analgesia was performed.

Pain following amputation is often poorly controlled despite the use of nerve blocks. We describe a novel pain management approach in a 56-year-old woman with episodes of poorly controlled pain following below-knee amputation despite a multimodal analgesic regimen with continuous sciatic nerve block. Effective analgesia was observed during those episodes when the nerve block catheter was briefly stimulated at low frequency using a nerve stimulator designed for regional anesthesia procedural guidance. This case report explains the utilization and rationale of this hybrid technique of combined peripheral nerve stimulation and locoregional analgesia via perineural nerve block catheters to augment analgesia.
