Influence of Spinal and General Anesthesia on Newborn’s Status

Abstract Introduction. The number of caesarean sections has drastically increased and thus arose the idea to examine the effect of the type of anesthesia on the neonates. The objective was to compare vital parameters in the neonates, born under general and spinal anesthesia. Method. A total of 120 patients with need for caesarean section have been divided in two groups of 60, of which the first was lead in general and the second one in spinal anesthesia. The first one was given propophol (2.0-2.5 mg/kg/tt) and succinil colin (1-1.5 mg/kg/tt). The anesthesia was lead with fentanil 0,005 mg/kg/tt and rocuronium bromide 0.4-0.6 mg/kg/tt. O2:N2O was 3:3 l/min. The second group was lead in spinal anesthesia. 2-3 ml Bupivacain 0.5% was spinally applied between L2-L3. Apgar score was defined in the neonates in the first and fifth minutes. The acido-basic status of the neonate was examined through pH values in the blood and the base excess. Results. In the first minute after birth giving with Apgar, 8 newborns 37(61,67%) were born to the group of patients with SA and 29 (48.33%) to the group of patients with GA. In 11 (18.33%) newborns born to the patients led with SA had Apgar score of 9-10, while only 3 (5%) of the newborns born to the patients led with GA had Apgar score of 9-10. Similar ratio was noted in the fifth minute after birth. Ph of the newborns’ blood as well as the base excess (BE) demonstrated significantly lower values in the group of patients led with SA than in the group of patients led with GA. Ph = 7.33 vs 7.37; BE=-4.57±1.8 vs -2.96±2.3. Conclusion. The newborns from the second group had significantly higher Apgar scores than those in the first group. The newborns’ relative acidose (lower SpO2 and BE) did not affect the newborns’ Apgar score in the first and fifth minute.
