The previous study revealed that many factors associated with incidences of hypotension. A cross sectional study from May 1, 2024 to July 31, 2024 was conducted on 107 patients undergoing cesarean section under spinal anesthesia. Chi-square tests, Fisher’s exact test, T-test, Mann-Whiney U test were used in univariate analysis to compare continuous data and categorical data appropriately. Multivariate logistic regression was reported in Odds Ratios (ORs) and 95% confidence interval. Incidence of hypotension was 57.9 %. The probability of hypotension increase with amount of crystalloid preload &gt;200 ml (adjusted OR = 0.28, 95%CI: 0.11 - 0.76, p-value = 0.013) and Time from spinal block to incision ≥10 min (adjusted OR = 3.84, 95%CI: 1.38 – 10.67, p-value = 0.010). Moreover nausea and vomiting (Crude OR = 3.57, 95%CI: 1.10 - 11.53, p-value = 0.034) was related to hypotension. The present results indicated that the incidence of hypotension after spinal anesthesia for cesarean section increased with amount of crystalloid preload &gt;200 ml and time from spinal block to incision ≥10 min.</p> Jitpisut Sribanpot Copyright (c) 2025 จิตต์พิสุทธิ ศรีบรรพต https://creativecommons.org/licenses/by-nc-nd/4.0 2025-07-04 2025-07-04 39 1 276754/1 15
