One hundred patients had major shoulder surgery with interscalene brachial and cervical plexus block anesthesia. Successful anesthesia was obtained by using this method in 82 patients. Failure was the result of incomplete anesthesia in 16 patients or the presence of a complication. ⋯ The block lasted a mean of eight hours, decreasing the need for postoperative analgesic medications. No postoperative medical complication developed. Ninety-one percent of the patients with successful blocks were satisfied with the procedure.

Five patients who underwent thoracic operations had an extradural catheter placed in the paravertebral space. X-ray contrast was injected through the catheters. ⋯ In one patient, contrast appears to have entered the extradural space and, in another who had no detectable analgesia, the contrast was probably dispersed intrapleurally. The significance of these findings is discussed.

Randomized Controlled Trial Comparative Study Clinical Trial
Continuous intercostal blockade after cardiac surgery.
The provision of analgesia using continuous bilateral intercostal blockade was compared with that provided by conventional i.v. narcotics for the first 48 h after cardiac surgery. The subjective quality of analgesia was significantly superior with the regional technique. However, pulmonary function tests, gas exchange, lung volume, and radiological and clinical evidence of pulmonary complications were not improved. The failure to reduce morbidity and the potential for complications such as pneumothorax, makes it difficult to recommend the regional analgesia technique in this situation.
