Review Meta AnalysisMornings after-periarticular liposomal bupivacaine infiltration does not improve analgesic outcomes beyond 24 hours following total knee arthroplasty: a systematic review and meta-analysis.
Periarticular local infiltration analgesia (LIA) is integral to multimodal analgesia following total knee arthroplasty (TKA); however, the duration of analgesia using traditional long-acting local anesthetics is often insufficient. LIA with slow-release liposomal bupivacaine may provide extended analgesia, but evidence of efficacy beyond the first 24 hours is conflicting. This meta-analysis compares the effects of periarticular liposomal and plain bupivacaine LIA on day 2 analgesic outcomes post-TKA. ⋯ Secondary outcome analysis did not uncover any additional analgesic, functional or safety advantages to liposomal bupivacaine on postoperative day 2 or 3. Results indicate that liposomal and plain bupivacaine LIAs are not different for extended postoperative analgesic outcomes, including pain control, opioid consumption, as well as functional and safety outcomes on days 2 and 3 post-TKA. High-quality evidence does not support using liposomal bupivacaine LIA for TKA.

Meta AnalysisDaring discourse: should the ESP block be renamed RIP II block?
During the time period 1984 to the turn of the millennium, interpleural nerve blockade was touted as a very useful regional anesthetic nerve blockade for most procedures or conditions that involved the trunk and was widely practiced despite the lack of proper evidence-based support. However, as an adequate evidence base developed, the interest for this type of nerve block dwindled and very few centers currently use it-thereby to us representing the rest in peace (RIP) I block. ⋯ Emerging meta-analysis data also raise concern and give cause to healthy skepticism regarding the use of ESPB for major thoracic or abdominal surgery. Against this background, we foresee that ESPB (and variations on this theme) will end up in a similar fashion as interpleural nerve blockade, thereby soon to be renamed the RIP II block.

Randomized Controlled TrialTransmuscular quadratus lumborum block for total laparoscopic hysterectomy: a double-blind, randomized, placebo-controlled trial.
The population of patients scheduled for total laparoscopic hysterectomy at our surgical center is heterogeneous concerning a multitude of demographic variables such as age, collateral surgery and malign or benign pathogenesis. A common denominator is moderate to severe postoperative pain and a substantial opioid consumption. A recent procedure specific postoperative pain management (PROSPECT) review found no gain from the regional techniques included. The transmuscular quadratus lumborum (TQL) block has shown promising results in recent trials for other types of surgery. The aim of the current study was to investigate the analgesic efficacy of the ultrasound-guided TQL block for total laparoscopic hysterectomy. ⋯ Preoperative bilateral ultrasound-guided TQL block did not reduce opioid consumption after total laparoscopic hysterectomy.

Randomized Controlled TrialEffectiveness of onabotulinumtoxinA (BOTOX) in pediatric patients experiencing migraines: a randomized, double-blinded, placebo-controlled crossover study in the pediatric pain population.
OnabotulinumtoxinA (OBTA) is approved for treating chronic headaches and migraines in adults, but there is limited scientific literature on the outcomes in pediatric patients. The aim of this study was to determine if subjects treated with OBTA reported a statistically significant improvement in the primary features (frequency, intensity, duration and disability scoring) associated with migraines compared with placebo at follow-up visits. ⋯ OnabotulinumtoxinA showed a statistically significant decrease in frequency and intensity of migraines compared with placebo. No adverse effects or serious adverse events related to the use of OBTA were reported. In the future, we aim to evaluate the specific nature of migraines, for example, quality/location of pain presented during an initial consult to predict the likelihood of OBTA being a truly effective modality of pain management for pediatric migraineurs.

Safety and outcomes of outpatient compared to inpatient total knee arthroplasty: a national retrospective cohort study.
Many factors are driving total knee arthroplasty to be performed more commonly as an outpatient (<24 hour discharge) procedure. Nonetheless, the safety of total knee replacements performed in the outpatient setting is not well established when compared with inpatient setting. The purpose of this study is to compare the postoperative outcomes of outpatient and inpatient total knee arthroplasties. ⋯ Outpatient total knee arthroplasty is associated with a higher composite risk of serious adverse events than inpatient procedures. Anesthesiologists and surgeons should inform patients and discuss this information when obtaining consent for surgery and planning for discharge timing.
