COMPARISON OF MATERNAL AND NEONATAL EFFECTS OF INTRATECHAL FENTANIL AND SUFENTANIL AS AN ADJUNT TO BUPIVACAINE USED FOR SPINAL ANESTHESIA IN CESAREAN SECTIONS

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
