Randomized Controlled TrialNausea, vomiting, sleep, and restfulness upon discharge home after outpatient anterior cruciate ligament reconstruction with regional anesthesia and multimodal analgesia/antiemesis.
We analyzed discharge outcome data after anterior cruciate ligament reconstruction (ACLR) under spinal anesthesia including a perineural femoral catheter and multimodal analgesia/antiemesis. The outcomes specifically addressed in this report are nausea, vomiting, and retching (NVR) and quality of sleep/difficulty falling asleep/daytime restfulness. ⋯ NVR and quality of sleep-restfulness after the described regional anesthetic with multimodal analgesia and antiemesis is reported. Smoking status was not a predictor of NVR, and gender and opioid consumption were not consistently predictive of NVR. The addition of a femoral nerve block to the described multimodal technique was not associated with NVR or quality of sleep-restfulness.

Ultrasound-guided and CT-navigation-assisted periradicular and facet joint injections in the lumbar and cervical spine: a new teaching tool to recognize the sonoanatomic pattern.
The aim of this study is to provide a teaching tool to facilitate the acquirement of periradicular and facet-joint infiltration techniques in the cervical and lumbar spine. ⋯ This teaching tool provides immediate CT-verification of sonographically identified structures and helps in the identification of bony landmarks, which are necessary for facet-joint and periradicular injections.

Altered blood flow in terminal vessels after local application of ropivacaine and prilocaine.
Ropivacaine is primarily a local anesthetic, but it also acts as a vasoactive agent. Case reports have described a critical reduction in blood flow when higher concentrations of ropivacaine were used for peripheral-nerve blocks. One hypothesis is that local application of ropivacaine in tissues supplied by end arteries reduces tissue blood flow because of arterial vasoconstriction. ⋯ The application of ropivacaine directly to a rat's tail artery diminished blood flow and lowered regional skin temperature. These effects were dose related. The use of ropivacaine at higher concentrations can, therefore, not be recommended if tissues supplied by end arteries might be affected.
