Knee arthroscopy is one of the most common orthopedic procedures done in the United States. It usually is performed as an outpatient procedure. This retrospective study was designed to assess the level of postoperative analgesia provided by the local knee block. ⋯ The severity of the knee pain was assessed using verbal pain rating scores during the anesthesia recovery period, before patients left the hospital, and again on the first postoperative day. Patients in group 2 had significantly lower pain scores compared with patients in group 1 during these periods. Results suggest that the local knee block provides superior postoperative analgesia for the knee arthroscopy patient.

[Along the anesthetic line: a new approach to the brachial plexus -- the subcoracoidal retrograde access].
Introduced is a new approach to the brachial plexus marked out in opposition to the common methods by some theoretical advantages. The needle is proceeded in an acute angle to the course of the plexus. Thus reduces the possibility of nerve damage. Second the insertion of catheter is simplified. The accidental puncture of the pleura is unlikely except in cases of gross deviations of the puncture instruction. In addition the plexus is hit before the musculocutaneous nerve leaves the brachial plexus. The objective of this investigation was to evaluate the usefulness of the subcoracoidal retrograde access in daily practice. Beside the influence of stimulating different fascicles or the necessity of reaching a defined low stimulation level on the success rate and effectiveness of the plexus blockade was investigated. ⋯ The described subcoracoidal retrograde access to the brachial plexus (SCREP) proved to be a safe and easy method with a low complication and high success rate compared with the known practised accesses. In contrary to other authors our findings do not support the connection either between success rate and stimulating certain fascicles nor achieving a defined lowest stimulation level.

Lumbar facet nerve (medial branch) blocks are often used to diagnose facet joint-mediated pain. The authors recently described a new ultrasound-guided methodology. The current study determines its accuracy using computed tomography scan controls. ⋯ : The computed tomography scans confirm that our ultrasound technique for lumbar facet nerve block is highly accurate for the target at all five lumbar transverse processes (medial branches T12-L4). Aberrant contrast medium spread is comparable to that of the classic fluoroscopy-guided method.

Randomized Controlled Trial Clinical TrialInterscalene brachial plexus anesthesia with ropivacaine 5 mg/mL and bupivacaine 5 mg/mL: effects on electrocardiogram.
Cardiotoxicity is the most severe complication of long-acting local anesthetics. The aim of this trial is to compare early signs of depression of cardiac conduction linked with the administration of either ropivacaine or bupivacaine for interscalene block. ⋯ Electrocardiographic recordings were similar in both groups, except for a significant prolongation of the PQ interval in the bupivacaine group at plasma levels below threshold for cardiotoxicity.

Randomized Controlled Trial Comparative Study Clinical Trial[Comparison of 4 techniques for internal saphenous nerve block].
To assess the efficacy of 4 techniques for internal saphenous nerve block with 10 mL of 1.5% mepivacaine. ⋯ The femoral nerve approach in the inguinal region, with nerve stimulator, to block the internal saphenous nerve led to a larger number of successful blocks than did the paravenous or transsartorial approaches, or the technique of subcutaneous infiltration between the tibial tuberosity and internal gastrocnemius muscle.
