Comparative StudyAccuracy and trending ability of the fourth-generation FloTrac/Vigileo System™ in patients undergoing abdominal aortic aneurysm surgery.
The fourth-generation FloTrac/Vigileo™ improved its algorithm to follow changes in systemic vascular resistance index (SVRI). This revision may improve the accuracy and trending ability of CI even in patients who undergo abdominal aortic aneurysm (AAA) surgery which cause drastic change of SVRI by aortic clamping. The purpose of this study is to elucidate the accuracy and trending ability of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery by comparing the FloTrac/Vigileo™-derived CI (CIFT) with that measured by three-dimensional echocardiography (CI3D). ⋯ The degree of accuracy of the fourth-generation FloTrac/Vigileo™ in patients with AAA surgery was not acceptable. The tracking ability of the fourth-generation FloTrac/Vigileo™ after aortic clamp was below the acceptable limit.

Observational StudyReliability and validity of the Japanese translation of the DN4 Diagnostic Questionnaire in patients with neuropathic pain.
The Douleur Neuropathique 4 questionnaire (DN4) is a simple and objective tool developed by the French Neuropathic Pain Group to screen for neuropathic pain. ⋯ The Japanese version of the DN4 was found to be a helpful tool for discriminating between neuropathic and non-neuropathic pain.

Meta Analysis Comparative StudyThe role of sciatic nerve block to complement femoral nerve block in total knee arthroplasty: a meta-analysis of randomized controlled trials.
Femoral nerve block (FNB) appears to have higher postoperative analgesic benefits compared with the patient-controlled analgesia (PCA) in total knee arthroplasty (TKA). However, the role of sciatic nerve block (SNB) as a complement to FNB remains controversial. We performed a meta-analysis assessing the benefits of the SNB as a complement to FNB, as well as comparing the efficacy of single-injection versus continuous SNB in TKA. ⋯ This meta-analysis provides evidence-based supports to the benefits of SNB as a complement to FNB in TKA. The combination sciatic-femoral nerve block appears to be the optimal choice for patients in high risk of postoperative opioids consumption or acute pain after TKA.

Randomized Controlled TrialLocal infiltration analgesia combined with a standardized multimodal approach including an adductor canal block in total knee arthroplasty: a prospective randomized, placebo-controlled, double-blinded clinical trial.
Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain. This study evaluates the technique of local infiltration analgesia (LIA), by comparing it to saline injections in addition to a standardized multimodal regimen including an adductor canal block. ⋯ Performing LIA in addition to a standardized multimodal analgesia regimen results in superior pain control, demonstrated as reduced opioid needs and lower resting and dynamic pain intensity scores on the first postoperative day after TKA. Further studies are needed to establish an LIA protocol that could maximize postoperative pain control.
