We report the rare complication of a retained peripheral nerve block catheter (PNBC). A 45-year-old man with intractable postamputation phantom limb pain was treated with continuous infusions via femoral and sciatic peripheral nerve catheters. ⋯ Magnetic resonance imaging (MRI) was inconclusive. Surgical exploration showed 15 cm of retained peripheral nerve catheter, which was removed.

Randomized Controlled Trial Comparative Study
The impact of dexmedetomidine added to ropivicaine for transversus abdominis plane block on stress response in laparoscopic surgery: a randomized controlled trial.
Intravenous dexmedetomidine is known to attenuate stress response in patients undergoing laparoscopic surgery. We investigated whether the addition of the highly selective alpha-2 adrenergic agonist dexmedetomidine into ropivacaine for ultrasound-guided transversus abdominis plane block could inhibit stress response during laparoscopic surgery, and determined the optimal dose of dexmedetomidine in it. ⋯ The addition of dexmedetomidine at the dose of 0.5 μg/kg into ropivacaine for ultrasound-guided transversus abdominis plane block is the optimal dose to inhibit stress response with limited impact on blood pressure and heart rate in patients undergoing laparoscopy gynecological surgery.

ReviewCombined spinal-epidural versus spinal anaesthesia for caesarean section.
Single-shot spinal anaesthesia (SSS) and combined spinal-epidural (CSE) anaesthesia are both commonly used for caesarean section anaesthesia. Spinals offer technical simplicity and rapid onset of nerve blockade which can be associated with hypotension. CSE anaesthesia allows for more gradual onset and also prolongation of the anaesthesia through use of a catheter. ⋯ In this review, the number of studies and participants for most of our analyses were small and some of the included trials had design limitations. There was some suggestion that, compared to spinal anaesthesia, CSE could be associated with a reduction in the number of women with intra-operative hypotension, but an increase in intra-operative nausea and vomiting requiring treatment. One small study found that low-dose spinal resulted in a faster time to effective anaesthesia compared to CSE. However, these results are based on limited data and the difference is unlikely to be clinically meaningful. Consequently, there is currently insufficient evidence in support of one technique over the other and more evidence is needed in order to further evaluate the relative effectiveness and safety of CSE and spinal anaesthesia for caesarean section.More high-quality, sufficiently-powered studies in this area are needed. Such studies could consider using the outcomes listed in this review and should also consider reporting economic aspects of the different methods under investigation.

Meta Analysis Comparative StudyThe efficacy and safety of continuous versus single-injection popliteal sciatic nerve block in outpatient foot and ankle surgery: a systematic review and meta-analysis.
Continuous popliteal sciatic nerve block (CPSNB) has been performed in outpatient foot and ankle surgery as a regional anesthesia method to relieve postoperative pain. Its efficacy as well as safety is yet to be established. There are two purposes of this study: (1) to validate the efficacy of CPSNB with regards to better pain relief and reduced analgesics consumption; (2) to assess the safety of CPSNB. ⋯ I; meta-analysis.

[Ultrasound-guided erector spinae plane block combined with pregabalin for post-herpetic neuralgia].
Objective: To analyze the clinical effect of ultrasound-guided erector spinae block combined with pregabalin on post-herpetic neuralgia (PHN) in the elderly. Methods: Sixty patients with post-herpetic neuralgia from January 2018 to January 2019 in the Department of Pain, First Affiliated Hospital of Bengbu Medical College were selected. The patients were divided into two groups according to the random number table (n=30): group C and ultrasound-guided erector spinae block (ESPB) group. ⋯ The difference was statistically significant (χ(2)=6.694, P<0.05). Adverse reactions were mild in both groups. Conclusion: Ultrasound-guided erector spinae block can effectively alleviate the pain of elderly patients with PHN in the chest, significantly reduce the dosage of oral drugs, improve the sleep quality of patients, and have higher safety.
