| Abstract |
BACKGROUND
Combined spinal epidural anesthesia (CSE) combines the rapid onset and intensity of a subarachnoid blockade with the flexibility of an epidural catheter, thereby allowing the intraoperative extension of anesthesia and postoperative epidural analgesia. This study investigated the effects of hyperbaric bupivacaine during CSE for lower limb orthopedic surgery in geriatric patients.
METHODS
Group 1 received a subarachnoid injection of 8 mg of bupivacaine and an epidural catheter. Group 2 received a subarachnoid injection of 5 mg of bupivacaine and fentanyl, 10 microgram and an epidural top-up with 3 ml saline. Group 3 received a subarachnoid injection of 5 mg of bupivacaine and fentanyl 10 microgram with an epidural top-up of 6 ml saline. Group 4 received a subarachnoid injection of 6 mg of bupivacaine and an epidural top-up with 6 ml saline. The maximal level of the sensory blockade, the time of onset to the maximal sensory blockade, the two segment regression time, the time for sensory regression to the tenth thoracic dermatome (T10) and the motor recovery to modified Bromage Scale 0 were compared. After recording the baseline systolic blood pressure and heart rate, the systolic blood pressure and heart rate were recorded at 5 min intervals.
RESULTS
There were significant differences in the two-segment regression times, the times to motor recovery between the groups. However, the intraoperative blood pressure and heart rate were similar.
CONCLUSIONS
In terms of the peri-operative side effects and recovery from the blocks, CSE was better for lower limb orthopedic surgery in geriatric patients than spinal anesthesia. |
