Abstract

Objectives: To study the incidence and factors of hypotension after spinal anesthesia in women undergoing cesarean section at Phra Nakhon Si Ayutthaya Hospital. Methods: This study was a prospective study in which data were collected from pregnant women undergoing a cesarean section under spinal anesthesia between January 1, 2023, and March 31, 2023. A total of 149 pregnant women participated in the study. Data were analyzed as mean, standard deviation, number, and percentage. Moreover, simple and multiple logistic regression analyses were used to establish relationships between the variables and reported in terms of OR and 95% confidence interval. Results: Of 149 pregnant women who underwent cesarean section, 78 women had hypotension (52.35%). Factors affecting the incidence of hypotension were heart rate>90 beats per minute (bpm) (Adjust OR = 1.05; 95%CI: 1.01-1.10, p = 0.009), birth weight >2800 gram (Adjust OR = 1.00; 95%CI: 1.00-1.01, p <0.001) and anesthetic level above T6 (Adjust OR = 12.27; 95%CI: 2.14-70.26, p= 0.005). Conclusions: The incidence of hypotension after spinal anesthesia in women undergoing a cesarean section at Phra Nakhon Si Ayutthaya Hospital was 52.35%. The associated risk factors with hypotension were heart rate>90 beats per minute (bpm), increased neonatal weight >2800 gram, and an anesthetic level above T6. These findings can be used as surveillance data to prevent hypotension induced by spinal anesthesia in cesarean section.
