Purpose:Cervical epidural analgesia is used for pain control in head and neck or upper arm. But it is not commonly used for the purpose of pure regional anesthesia for upper arm surgery. Therefore, we investigated the usefulness of cervical epidural anesthesia (CEA) as a method of regional anesthesia for arteriovenous bridge graft (AVBG) for hemodialysis at upper arm and evaluated the effects of CEA on hemodynamics and respiration.
Methods:One hundred-fifty chronic renal failure patients scheduled for AVBG were randomly assigned. In the sitting position, an epidural catheter was inserted at C6-7 or C7-T1 and 15 ml of 0.375% ropivacaine with fentanyl 20?g was injected. Analgesic level, blood pressure and heart rate were measured at 5-minute intervals after injection of the drug. Arterial blood sampling was taken for aBGA before and twenty minutes after CEA.
Results:Average anesthetic dermatomalsensory levels were C3.4±1.2∼T5.7±2.8. During surgery, hypotension was noted in 49% of patients. It was treated with ephedrine or phenylephrine i.v. Baseline PaCO2 changed from 42.4±2.9 mmHg to 44.6±3.6 mmHg.
Conclusions:The above results suggest that CEA is suitable for AVBG at upper arm as a regional anesthesia.
