In order to examine the effects of cervico-thoracic epidural block with 1.5% lidocaine on ventilatory and circulatory responses to carbon dioxide, the authors studied the CO2-ventilatory response curves and the changes in heart rate (HR) and blood pressure (AP) to rebreathing of exhaled gas before and after the block in healthy volunteers. Neither resting ventilation nor ventilatory response to CO2 was affected by the epidural block (mean analgesic level extended from C4 to T7); the slope of… CONTINUE READING
