Objective: To compare the effects of fentanil, and sufentanil added to hyperbaric bupivacaine in patients scheduled for cesarean section under spinal anesthesia. Material and Method: 60 pregnants has divided into 2 groups. Intratechally  hyperbaric 0.5% bupivacaine+ 20 mcg fentanyl has administered for Fentanyl Group (Group F) and hyperbaric 0.5 % bupivacaine +5 mcg sufentanyl has administered for Sufentanyl Group (Group S). Hemodynamic parametres, maximum sensory block level, time to reach this level, regression  of the sensory block to T10 dermatome, degree of motor block (Bromage score ), and resolution time, perioperative visual analogoue scale (VAS) score, complet (CAD) and efective analgesia duration (EAD), postoperatif analgesic requirement and consumption were recorded. Umblical arterial blood gas analyse, APGAR scores, surgical anaesthesia and relaxation quality and quality of analgesia were evaluated. Results : Time to regression of sensory block to T10  and resolution of the motor block were prolonged in the sufentanil group (p<0.05). VAS scores at birth, uterine exteriorization, and at 2., and 6. hours of the block were found to be higher in the fentanil group (p<0.05). At Group S while CAT and EAT were higher, PCA requirement clips and amounts were lower.Surgical anaesthesia and relaxation quality and patient satisfaction were better in Group S. APGAR scores and blood gas analyses results were similar. Itching rate was higher in Group S Conclusion: we suggest that sufentanil added to intrathecal bupivacaine may be preffered for cesarean section  because of better patient and surgeon satisfaction, prolonged analgesia time, decreased analgesic requirements and minimal adverse effects.
