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.

Randomized Controlled Trial Comparative Study Clinical Trial
Intrathoracic intercostal nerve block with phenol in open chest surgery. A randomized study with statistical evaluation of respiratory parameters.
Seventy-three patients who underwent thoracic surgery were randomly selected for intraoperative intercostal nerve block using phenol (32 block and 41 control subjects). The patients were divided into three groups: pneumonectomies, lobectomies and explorative thoracotomies and evaluated by pain level, respiratory function parameters (VT, IRV, ERV, VC) and blood-gas analysis, both six and 24 hrs after surgery. The patients who had intraoperative nerve block using phenol enjoyed a more comfortable postoperative period. In particular, respiratory parameters were statistically better.

Randomized Controlled Trial Comparative Study Clinical Trial
Effects of the addition of potassium to prilocaine or bupivacaine. Studies on brachial plexus blockade.
A double-blind comparison of prilocaine and prilocaine plus potassium chloride, and of bupivacaine with bupivacaine plus potassium chloride, in brachial plexus blockade (axillary approach) was obtained in two groups of 20 patients. The addition of potassium chloride made no difference to the characteristics of the block with prilocaine, but resulted in a more rapid onset of sensory loss when added to bupivacaine.
