Randomized Controlled Trial Comparative Study Clinical Trial
Interpleural block for patients with multiple rib fractures: comparison with epidural block.
Interpleural block (IPB) was compared with epidural block (EB) in 17 adults with unilateral multiple rib fractures and hemopneumothorax. The study was a randomized, crossover, before-after trial on the first and second hospital days. An IPB catheter was inserted along with a chest tube, and an upper thoracic EB was also established in the same patient. ⋯ Serum levels of lidocaine were similar and in the safe range. The technique of IPB seemed to be easier than EB. In conclusion, IPB with lidocaine is as effective for pain relief as EB.

Comparative StudyOn the relative potency of amino-amide local anaesthetics in vivo.
With the aim of comparing the analgesic effectiveness of lidocaine, prilocaine, bupivacaine and etidocaine in vivo, a study of the relationships between dose and duration of infraorbital nerve block (IONB) of various intensities (IONB degrees 3-10) was performed in the rat. With increasing doses longer durations of action were obtained. Further analyses were performed using multiple regression analysis. ⋯ The difference between these agents with respect to their duration of action at all dose levels amounted to 11 +/- 3 minutes (M +/- s.e.m.) for etidocaine vs. lidocaine (IONB degree 10), 27 +/- 4 min for prilocaine vs. lidocaine and 54 +/- 5 min for bupivacaine vs. etidocaine (IONB degree 3). For all other comparisons the log (dose)-duration lines deviated from parallelism, i.e. differences between agents with respect to their duration of action were found to be dose-dependent. The slopes of the log (dose)-duration lines were found to correlate closely to the log (partition coefficient) and log (protein binding) of the investigated agents.

Randomized Controlled Trial Clinical Trial[Inguinal funicular block in vasectomy].
The analgesic efficacy of inguinal funicular block with 10 ml carbocaine 1% as a supplement to local infiltration analgesia of the vas deferens was investigated in patients undergoing vasectomy. Pain/discomfort during vasectomy and on the first and third day postoperatively were investigated using a questionnaire. ⋯ There was significantly less intraoperative pain on the side of the active inguinal funicular block (p < 0.0001), but no significant differences were found at the first and third postoperative day (p = 1.16-1.19). Inguinal funicular block can be recommended as a supplement to the usual use of local infiltration analgesia of the vas deferens.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of digital versus metacarpal blocks for repair of finger injuries.
This study compared efficacy, degree of discomfort, and time to anesthesia of digital blocks and metacarpal blocks for digital anesthesia. ⋯ Digital block and metacarpal block, as described in this study, are equally painful procedures. Digital block, however, is more efficacious and requires significantly less time to anesthesia for the injured finger.
