title: Cryoanalgesia for post-thoracotomy pain relief.
abstract: 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.
