Improvement in healthcare delivery depends on the ability to measure outcomes that can direct changes in the system. An overview of quality indicators within the field of regional anaesthesia is lacking. This systematic review aims to synthesise available quality indicators, as per the Donabedian framework, and provide a concise overview of evidence-based quality indicators within regional anaesthesia. ⋯ In addition, most indicators (84%) were based on low levels of evidence. Our study is an important first step towards describing quality indicators for the provision of regional anaesthesia. Future research should focus on the development of structure and process quality indicators and improving the methodological quality and usability of these indicators.

Moderate-to-severe postoperative pain persists for longer than the duration of single-shot peripheral nerve blocks and hence continues to be a problem even with the routine use of regional anaesthesia techniques. The administration of local anaesthetic adjuncts, defined as the concomitant intravenous or perineural injection of one or more pharmacological agents, is an attractive and technically simple strategy to potentially extend the benefits of peripheral nerve blockade beyond the conventional maximum of 8-14 hours. Historical local anaesthetic adjuncts include perineural adrenaline that has been demonstrated to increase the mean duration of analgesia by as little as just over 1 hour. ⋯ Neither perineural dexmedetomidine nor dexamethasone fulfils all the criteria of the ideal local anaesthetic adjunct. Dexmedetomidine is limited by side-effects such as bradycardia, hypotension and sedation, and dexamethasone slightly increases glycaemia. In view of the concerns related to localised nerve and muscle injury and the lack of consistent evidence for the superiority of the perineural vs. systemic route of administration, we recommend the off-label use of systemic dexamethasone as a local anaesthetic adjunct in a dose of 0.1-0.2 mg.kg-1 for all patients undergoing surgery associated with significant postoperative pain.

Case ReportsAllergic contact dermatitis to a dye or alcohol in a chlorhexidine-based skin preparation: A case report.
This case report describes a patient who developed allergic contact dermatitis to a chlorhexidine skin preparation applied for a transversus abdominis plane block, but not to a different chlorhexidine solution applied to the surgical field. The patient had presented for an elective inguinal hernia repair. He had a known history of anaphylaxis to non-steroidal anti-inflammatory medication but was otherwise well. ⋯ The skin preparations differed in the dyes and alcohols that they contained. The dyes or alcohol in the preparation for the transversus abdominis plane block were therefore considered the likely cause of this patient's allergic reaction. Dyes and alcohols should be considered as a cause of skin allergy in the perioperative setting.

Randomized Controlled Trial
Pretreatment with Pectoral Nerve Block II Is Effective for Reducing Pain in Patients Undergoing Thoracoscopic Lobectomy: A Randomized, Double-Blind, Placebo-Controlled Trial.
Although video-assisted thoracoscopy has a smaller incision than traditional surgery, the postoperative pain is still severe. Ultrasound-guided pectoral nerve block (PECS) II is a new technique that can reduce pain in patients, and it had not been reported in the analgesia after thoracoscopic lobectomy. ⋯ Preconditioning of PECS II can stabilize the intraoperative circulation and significantly reduce pain and the consumption of opioids after operation.

Persistent headaches and migraines are common in pediatrics with various treatment options. The sphenopalatine ganglion (SPG) has been identified as communicating with the parasympathetic autonomic nervous system and pain receptors. In adults, SPG block is an established treatment but there is no published literature in pediatrics. ⋯ With 100% technical success, statistically significant pain reduction, and no complications, we support SPG block in the pediatric population as a simple, efficacious, and safe treatment option for refractory headaches. It is routinely performed in less than 10 minutes and commonly negates the need for inpatient headache pain management. Given its minimal invasivity, we support the use of SPG blockade as a therapeutic treatment in refractory pediatric migraines as it reduces the need for intravenous medications, prolonged pain control, or hospital admission.
