Abstract:
:Epidural clonidine produces analgesia in humans with acute and chronic pain. Its use is limited because of short-lasting analgesia, hemodynamic depression, sedation, and respiratory depression. Intrathecal guanfacine has a longer duration of action than intrathecal clonidine. The present study compares these two drugs administered epidurally. Pulmonary artery, carotid artery, and epidural catheters were inserted into five goats. Each animal received guanfacine 5 mg/10 mL, clonidine 750 micrograms/10 mL, or a 10-mL saline control solution on separate occasions. Antinociception (tested via a point pressure stimulation device), arterial blood pressure, heart rate, cardiac output, pulmonary capillary wedge pressure, and arterial and mixed venous blood gases were measured every 30 min for 8 h. Guanfacine produced a longer duration of antinociception (guanfacine = 8 h vs clonidine = 5.5 h). Increases in PaCO2 were more pronounced in the clonidine group. There were no marked hemodynamic differences between the two drugs. Pretreatment with epidural idazoxan, an alpha 2-antagonist, blocked the antinociceptive effects of guanfacine. Because of a longer duration of action and less respiratory depression, epidural guanfacine may be superior for postoperative analgesia and chronic pain syndromes.
