The Effect of Fluid Preloading on the Incidence of Hypotension During Spinal Anesthesia

Abstract

Background: Small doses of local anaesthetic are injected into the CSF fluid in the subarachnoid region to produce spinal anaesthesia (SA). Aim: This paper was contributed to study the effect of fluid preloading on the incidence of hypotension during spinal anaesthesia. Patients and methods: This cross-sectional study recruited 45 patients in different hospitals in Iraq for a study that ranged from the 15th of June in the year 2021 to the 24th of August in the year 2022. This paper dealt with the study of the effect of fluid preload on the incidence of hypotension during spinal anaesthesia, as it included in the clinical characteristics’ tests related to mothers or women who underwent caesarean delivery under spinal anaesthesia. This study divided the collected data into two groups, one of which was the patient group, which included patients who underwent spinal anaesthesia, which this group is considered as the co-loading group, which included 23 patients out of the total number of patients' data collected, while it was represented by the preload group, which included women who underwent spinal anaesthesia, which included 22 patients out of the total number of patients. This paper was conducting and analysing the collected data by SPSS. Discussion: The difference was that when their systolic blood pressure fell to 90 mm Hg, they began using a vasopressor heavily. The current finding found the Apgar score of the co-load who patients group (8.91) was found higher that preload who control group (8.95%) within 5 min in compare 1 min. In the present analysis, there was also a statistically significant variation between the co-load (81.4%) and pre-load (45.3%) groups in terms of the incidence of hypotension. The incidence of hypotension was statistically significantly different between the preload (80%) as well as co-load (51%) groups, according to research through (Oh AY et al., 2014). Both trials revealed that the co-load group's blood pressure dramatically decreased. Conclusion: This study found that (45.3%) were within the preload group as a control group and (81.4%) in the co-load group as patients group had hypotension. Preloading was, therefore, more effective than co-loading in preventing spinal anesthesia-induced hypotension of cesarean section moms. It may not be essential to postpone surgery to provide a preload of liquids.
