Introduction: Local anesthetics are also
considered to be potentially toxic to the cardiovascular system since they act
on ion channels in nerve cell membranes as well as in other tissues that can be
stimulated.
Aim: In this study we aimed to compare
cardiotoxicity levels of both drugs with brain natriuretic peptide (BNP)
protein level in patients undergoing combined spinal epidural anesthesia and
postoperative analgesia when given bupivacaine and levobupivacaine at
equipotent doses.
Materyal
and Method: In this prospective, randomized, double-blind study a total of
30 patients, aged 25-70 years, who were included in the American Society of
Anesthesiologists (ASA) I-III risk class and underwent total knee arthroplasty
surgery, were included in the study. Patients were randomized as Group I (n =
15) Levobupivacaine and Group II (n = 15) bupivacaine and combined spinal-epidural
anesthesia was administered. The operation follow-up of patients were evaluated
with the systolic arterial pressure (SAB), the diastolic arterial pressure
(DAB), the mean arterial pressure (MAP) and the heart rate (HR), and
postoperative follow-up with SAB, DAB, KH, visual analogue scale (VAS) values
were monitored at zero minute, 1st, 6th, 12th and 24th hour. BNP levels were
measured at 5th minute after spinal anesthesia, sensory block at thoracal level
10 and post-operative 24th hour.
Results:
A statistically significant difference was found in the VAS values measured
at postoperative 12th hour and 24th hour in favor of levobupivacaine group (p
<0.05). In the comparison of BNP levels between the groups, there was no
statistically significant difference between the two groups at all measurement
times (p> 0.05).
Conclusion: Similar results were obtained
in intraoperative and postoperative BNP levels when using levobupivacaine and
bupivacaine in equal doses for both spinal anesthesia and epidural analgesia.
