Small-incision manual extracapsular cataract extraction using deep-topical, nerve-block anesthesia.
To determine whether deep-topical anesthesia is suitable for small-incision manual extracapsular cataract extraction (ECCE). ⋯ Deep-topical, nerve-block anesthesia provides anesthesia with sufficient quality for small-incision manual ECCE.

Randomized Controlled Trial Clinical Trial[Application of separating brachial plexus block combined with preoperative analgesia by patient controlled intravenous analgesia in tendon repair].
To investigate whether the separating brachial plexus block combined with preoperative analgesia by patient controlled analgesia (PCA) can be applied in tendon repair and postoperative active or passive functional exercise. ⋯ The separating brachial plexus block combined with preoperative analgesia by 2 kinds of PCIA dispensation can be both applied in tendon repair, but the separating effect of brachial plexus block of group B was superior to the group C.

Randomized Controlled Trial Comparative Study Clinical Trial
Popliteal sciatic perineural local anesthetic infusion: a comparison of three dosing regimens for postoperative analgesia.
This randomized, double-blind study investigated the efficacy of continuous and patient-controlled ropivacaine infusion via a popliteal sciatic perineural catheter in ambulatory patients undergoing moderately painful orthopedic surgery of the foot or ankle. ⋯ This study demonstrates that when providing analgesia with 0.2% ropivacaine via a popliteal sciatic perineural catheter after moderately painful surgery of the foot or ankle, a continuous infusion is required to optimize infusion benefits. Furthermore, adding patient-controlled bolus doses allows for a lower continuous basal rate and decreased local anesthetic consumption and thereby increases the duration of infusion benefits when in an ambulatory environment with a limited local anesthetic reservoir.

Lumbar facet (zygapophysial) joints have been implicated as the source of chronic pain in 15% to 45% of patients with chronic low back pain. Diagnosis may be confounded by false-positive results with a single diagnostic block and administration of anxiolytics and narcotics prior to or during the diagnostic facet joint blocks. ⋯ The administration of sedation with midazolam or fentanyl is a confounding factor in the diagnosis of lumbar facet joint pain in patients with chronic low back pain. However, this study suggests that if strict criteria including pain relief and ability to perform prior painful movements is used as the standard for evaluating the effect of controlled local anesthetic blocks, the diagnostic validity of lumbar facet joint nerve blocks may be preserved.
