Abstract

GONZALEZ CABRAL, Daiana; DELGADO MAIDANA, Walter; NUNEZ LEDESMA, José  and  VEGA CARDUZ, Evanhy. Spinal anesthesia with isobaric bupivacaine in cesarean sections. An. Fac. Cienc. Méd. (Asunción) [online]. 2022, vol.55, n.3, pp.71-75. ISSN 1816-8949.  https://doi.org/10.18004/anales/2022.055.03.71.

In anesthesia for caesarean sections, spinal anesthesia with hyperbaric bupivacaine is the usual choice in our setting. There are two forms of bupivacaine available, isobaric (BI) and hyperbaric (BH). The use of BI is infrequent, so it is relevant to know the experience in its use for anesthesia in obstetric surgeries. The objective of the study was to characterize the use of BI in spinal anesthesia for cesarean sections. An observational, descriptive, cross-sectional study was carried out in 23 patients who received spinal anesthesia with BI. The average age was 28  5 years, the average dose of BI used was 9.4 mg. The average latency was 90 seconds and the time for establishment of adequate anesthesia was on average 4.9 minutes. In 82.6% of the cases, the anesthetic level reached dermatome T4. In 21.7% it was necessary to administer ephedrine to increase blood pressure. Minor adverse effects occurred in 52.1%. At 24 hours, the pain was null in 56.5% and mild in 43.5% of cases. In conclusion, it was found that the patients reached an adequate sensory level in a short time, with an average dose of BI of 9 mg. Few patients required administration of a vasopressor to increase blood pressure. Adverse effects were minor in almost half of the patients. In the postoperative period, most of the patients did not present pain.
