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.
