Maternal and fetal effects of intratecal bupivacaine and levobupivacaine during cesarean section [Sezaryen operasyonlarinda i̇ntratekal levobupi̇vakai̇;n ve bupi̇vakai̇ni̇n maternal ve fetal etki̇leri̇ni̇n karşilaşrilmasi]

Objective: for cesarean section,regional anesthesia is preferred a technique to general anesthesia because of maternal and fetal high morbidity and mortality. complications of regional anesthesia techniques are rarely high sensorial block or local anesthetic toxicity. we aimed to compare maternal and fetal effects of intratecal bupivacaine and levobupivacaine during cesarean section. methods: forty,asa i or ii parturients volunteers,between 20 and 45 years old and 36-41 gestational weeks undergoing elective cesarean delivery were enrolled in our study. patients who were morbid obese,preeclamptic and having diabetes mellitus,enfection in enjection area,contrandications to spinal anesthesia and allergic to drugs that would be used were not enrolled in the study. standart monitorization including sistolic,diastolic and mean arterial pressure; heart rate,peripheral oxygen saturation were recorded. 10ml kg -1 ringer lactate infusion was administered to prevent hypotension before spinal anesthesia to all patients and ephedrine was used in case of hypotension. 0.5% levobupivacaine 10 mg or 05% bupivacaine 10 mg was randomly injected through spinal needle in the lateral decubitus position. block levels were recorded from the onset of the spinal until 180 minutes. motor block was assessed using bromage scale while sensory block was assessed by pinprick sensation and sympathetic blockage were assessed by cotton with alcohol. in addition,complications (hypotension,nausea-vomiting,bradycardia,convulsions,urine retention,post spinal headache) that could exist,and apgar values of newborn at first and fifth minutes and umbilical cord blood gases were recorded. results: at the end of the study in the bupivacaine group decrease of heart rate,hypotension and peripheral oxygen saturation were detected and longer duration of sensory block,slower sempathetic block and less motor blockage were noted in the levobupivacaine group. conclusion: in conclusion we have shown that,levobupivacaine was less toxic than bupivacaine group and more potent anestesic and had no effects unwished for neonates during spinal anesthesia for cesarean delivery.
