He also does not indicate the surveillance method used by him to determine the complication rate.A 14-gauge angiocatheter may be a safe method for performing a thoracentesis, but it has not been proved so in a randomized, prospective study. Our study1 demonstrated that the needle catheter technique, when used by physicians in training, is complicated by a substantial rate of pneumothorax. This method had been previously accepted at our institution as the method of choice for performing a thoracentesis. We feel that any thoracentesis
