“…Maternal factors such as weight, BMI, [14][15][16] weight gain during pregnancy, 20 abdominal girth, and distance between the symphysis pubis and fundus 21 have been reported to be able to predict SAIH due to aortocaval compression. 16,[22][23][24] However, fetal weight, which was identified as a risk factor for SAIH in this study, may represent this compression more directly.…”

“…Compared to the parturients without SAIH, those with SAIH had a significantly lower baseline SBP (122 [interquartile range = 114-130] vs 130 [120-143] mmHg, p < 0.001), heavier large fetal weight (3098 [2742-3345] vs 2930 [2576-3266] g, p < 0.001), were more often multiparous (259 [60.4%] vs 261 [45.8%], p < 0.001), had a higher percent change in lowest SBP (33 [27-39] vs 19 [12][13][14][15][16][17][18][19][20][21][22][23][24][25]%, p < 0.001), and shorter time to lowest SBP after spinal anesthesia (14.9 [10][11][12][13][14][15][16][17][18][19][20] vs 15.9 [10][11][12][13][14][15][16][17][18][19][20] minutes, p < 0.001).…”

Background: The aim of this study was to examine the risk factors associated with the use of vasopressors to prevent hypotension that occurs after spinal anesthesia during caesarean section. Although the prophylactic use of vasopressors is already suggested as routine care in many parts of the world, the occurrence of spinal anesthesia-induced hypotension (SAIH) is still common in parturients. Methods: This retrospective study included parturients receiving elective caesarean deliveries under spinal anesthesia from April 2016 to March 2020. Risk factors related to ephedrine dosage were analyzed using a hurdle model, and risk factors related to SAIH were further analyzed with logistic regression. Results: Five risk factors, namely maternal body mass index (BMI, p < 0.001), baseline systolic blood pressure (SBP, p < 0.001), baseline heart rate (HR, p = 0.047), multiparity (p = 0.003), and large fetal weight (p = 0.005) were significantly associated with the requirement for ephedrine. Furthermore, a higher ephedrine dosage was significantly associated with maternal BMI (p < 0.001), baseline SBP (p < 0.001), baseline HR (p < 0.001), multiparity (p = 0.027), large fetal weight (p = 0.030), maternal age (p = 0.009), and twin pregnancies (p < 0.001). Logistic regression analysis also showed that the same five risk factors - maternal BMI (p = 0.030), baseline SBP (p < 0.001), baseline HR (p < 0.001), multiparity (p < 0.001), and large fetal weight (p < 0.001) - were significantly associated with SAIH, even in cases where vasopressors were administered. Conclusion: These findings can be useful for clinicians when deciding the dose of prophylactic ephedrine or phenylephrine to prevent SAIH.

“…Fakherpour et al 31 found that gravidity ≥4 and history of hypotension were associated with spinal anesthesia-induced hypotension. Parthasarathy et al 32 found that the distance between the symphysis pubis and the fundus and abdominal girth could effectively predict spinal anesthesia-induced hypotension, however, this correlation was not confirmed by Kuok et al 33 and Günüşen et al 34…”

Background Hypotension following spinal anaesthesia is one of the most common complication leading to poor maternal and fetal outcomes. This study is designed to assess the association between anthropometric parameters and incidence of hypotension in parturient's undergoing cesarean section under spinal anaesthesia. Aim and objectives The aim of this study is to evaluate if maternal anthropometric parameters like abdominal circumference, vertebral column length and symphysiofundal height has any effect on incidence of hypotension during cesarean section under spinal anaesthesia. Methods 100 term pregnant women aged between 18-45 years, ASA-PS grade 1-2 undergoing cesarean section under spinal anaesthesia were included in the study.The preoperative anthropometric parameters - Abdominal circumference(AC), symphysiofundal height(SFH) and vertebral column length (VC)were recorded. Spinal Anaesthesia was induced with 2ml of 0.5% Heavy Bupivacaine at the level of L2-L3. The haemodynamic parameters were recorded every 2 minutes up to 10 minutes and thereafter every 5 minutes up to 20 minutes after spinal anesthesia. Correlation analysis (Spearman's rank test) was performed to nd the correlations of AC , VC length and SFH with the incidence of hypotension. Statistical analysis was done using Chi square test, t test and one way ANOVA . P < 0.05 was considered statistically signicant . ResultsThe incidence of hypotension was directly proportional with increasing SFH and AC. The incidence of hypotension was 83% with SFH of 36–40 cm, 57% with AC 95–99cm, 78% with VC length of 50-55 cms and 22% with VC length of 56-60 cms which was statistically signicant ( P < 0.001). Conclusions The anthropometric measurements like AC, VC length and SFH can be a reliable predictor of hypotension and level of sensory blockade and can help in optimising the dose of spinal anesthetic drug .
