The administration of intravenous lidocaine during the peri-operative period may improve pain management after paediatric surgery. ⋯ The use of lidocaine is associated with improved pain management. However, further studies are needed to increase the level of evidence and determine the optimal administration regimen for pain management.

Randomized Controlled Trial
A randomised controlled trial of the effect of intra-articular lidocaine on pain scores in inflammatory arthritis.
Chronic pain in inflammatory arthritis (IA) reflects a complex interplay between active disease in a peripheral joint and central pronociceptive mechanisms. Because intra-articular lidocaine may be used to abolish joint-specific peripheral input to the central nervous system, we aimed to validate its use as a clinical tool to identify those patients with IA whose pain likely incorporates centrally mediated mechanisms. We began by investigating whether there was a placebo response of intra-articular injection in patients with IA 1:1 randomised to receive intra-articular lidocaine or control (0.9% saline). ⋯ Firstly, the placebo effect of intra-articular injection was low: compared to baseline, the mean pain NRS score 5-minutes postinjection was reduced by 3.5 points in the lidocaine group vs 1.2 points in the control group. Secondly, postlidocaine NRS scores were significantly higher in those with a high (>18) baseline painDETECT score, fibromyalgia, and low-pressure pain threshold at the trapezius ( P = 0.002, P = 0.001, P = 0.005, respectively). Persistent high pain after intra-articular lidocaine injection could be used as an indicator of pronociceptive mechanisms that are centrally mediated, informing centrally targeted analgesic strategies.

Randomized Controlled Trial Comparative Study
Desflurane versus sevoflurane anesthesia and postoperative recovery in older adults undergoing minor- to moderate-risk noncardiac surgery - A prospective, randomized, observer-blinded, clinical trial.
The effect of volatile anesthetics on postoperative recovery in older adults is still not entirely clear. Thus, we evaluated the effect of desflurane versus sevoflurane anesthesia on speed of postoperative recovery in older adults eligible for same-day discharge. We further evaluated the incidence of postoperative nausea and vomiting (PONV), bispectral index (BIS) values, and S100B concentrations. ⋯ Despite previous reports, we did not observe significant faster recovery times after desflurane anesthesia. Both volatile anesthetics may be appropriate for same-day discharge in older adults.

Randomized Controlled Trial
Intravenous Versus Peribulbar Dexmedetomidine as an Adjunct to Local Anesthetics in Strabismus Surgery: A Randomized, Double-blinded Clinical Trial.
Dexmedetomidine has not been adequately studied as an adjuvant to peribulbar anesthesia in strabismus surgery. ⋯ Peribulbar dexmedetomidine outperforms intravenous dexmedetomidine in terms of postoperative analgesia and motor block duration when used as an adjunct to peribulbar anesthesia for strabismus surgery. However, the intravenous group had significantly shorter surgical times.

Lumbar and sacral tattoos are popular amongst all ages. Some physicians are concerned that passing a needle through a pigmented area during lumbar puncture may deposit toxic material into the central nervous system, resulting in late complications. ⋯ There is insufficient evidence to endorse placement of a needle through a tattoo into the neuraxis before it is completely healed. The Fermi paradox 'absence of evidence is not evidence of absence of effect' still holds in light of emerging evidence that tattoos may be linked to lymphoma.
