Randomized Controlled Trial Comparative Study Clinical TrialCryoanalgesia for post-thoracotomy pain relief.
A randomized study comparing the postoperative requirements of narcotics of three groups of patients (Group I: no analgesia; Group II: internal intercostal nerve block; Group III: cryoanalgesia) was conducted. This study was performed in order to assess the efficiency of cryoanalgesia versus internal intercostal nerve block to obtain pain relief after thoracotomy. Regarding post-operative narcotic requirements (Piritramide-Dipidolor), there was no significant difference between Group I and Group II patients, but patients from Group III required a significantly lower amount of narcotics during the first 36 postoperative hours (p less than 0.01). We conclude that, although cryoanalgesia does not provide complete post-thoracotomy pain relief, it is however an easy and safe method and is more efficient than internal intercostal nerve block for pain relief after thoracotomy.

Randomized Controlled Trial Comparative Study Clinical Trial
Quality of axillary brachial plexus block. Comparison of success rate using perivascular and nerve stimulator techniques.
A perivascular catheter technique (PVT) and a nerve stimulator technique (NST) for axillary brachial plexus block were compared in terms of quality: complete, incomplete or failed blocks. In a randomised series, 30 PVT blocks and 30 NST blocks were performed by three staff anaesthetists. ⋯ In both groups eight patients needed supplementation with additional conduction blocks of 1-3 peripheral nerves. It is concluded that a nerve stimulator technique may increase the success rate of axillary brachial plexus block to some extent.
