Regional Spinal Anesthesia for C-section and Postpartum Pomeroy. Administering a Local Anesthetic at a <60 or >60 Seconds Injection Rate
Abstract
Objective. To identify any potential relationship between the rate of administration of the anesthetic agent in the subarachnoid space and the development of hypotension and side effects in patients scheduled for C-section and postpartum Pomeroy.
Methods. Observational case series study at the Instituto Materno Infantil-Hospital La Victoria. 60 patients who underwent a C-section procedure or a postpartum Pomeroy were included and two variables were measured: the rate of administration of the anesthetic agent in the subarachnoid space (<60 or >60 seconds) and the effects of two anesthetics combined (0.5 % hyperbaric bupivacaine 7.5 mg, plus morphine 100 mcg, and 0.5 % hyperbaric bupivacaine 12 mg, plus fentanyl 20 mcg). The mean blood pressure values were recorded, together with any side effects following the administration of the anesthetic agent at 1, 5, 10 and 15 minutes and at the end of surgery.
Results. The evidence obtained suggests that there are no differences in the hemodynamic effects of the combination or the anesthetic technique used, nor with regards to the occurrence of side effects.
