Key result
Greater symphysis pubis-xiphoid distance and combined newborn and placenta weights were significantly correlated with higher sensory block levels and increased incidence of hypotension (P < 0.05).
Why the study?
Hypotension is a serious complication caused by spinal anesthesia that places both the mother and fetus at increased risk, prompting an investigation into the effects of uterine size with or without abdominal obesity on sensory block level.
Do SPX values and combined newborn and placenta weights predict sensory block level and vasopressor requirement in term parturients receiving spinal anesthesia?
Observational (n=125)
Do SPX values and combined newborn and placenta weights predict sensory block level and vasopressor requirement in term parturients receiving spinal anesthesia?
SPX values and combined newborn and placenta weights are predictive of sensory block level and hypotension risk in parturients receiving spinal anesthesia.
SPX and newborn/placenta weights may predict sensory block and ephedrine needs in spinal anesthesia; leaves open prospective validation before clinical adoption.
Background/aim: Hypotension is a serious complication caused by spinal anesthesia that places both the mother and fetus at increased risk. We aimed to investigate the effects of uterine size with or without abdominal obesity on sensory block level of pregnant women receiving spinal anesthesia. Materials and methods: This study included 125 term parturients who underwent cesarean section. Motor and sensory block characteristics, the distance between the symphysis pubis and the fundus (SPF), the distance between the symphysis pubis and the xiphoid (SPX), newborn and placental weights, adverse effects, and doses of ephedrine were recorded. Results: Sensory block level and ephedrine dose were significantly correlated with the SPX and the combined newborn and placenta weights (P < 0.05). The incidence of hypotension was related to the SPX and the combined newborn and placenta weight (P < 0.05). There was no correlation between the SPF and sensory block level or ephedrine dose. The sensory block level was higher for patients who had greater SPX values and higher combined newborn and placenta weights. The incidence of hypotension and the ephedrine dose were also higher in these subjects. Conclusion: SPX values and combined newborn and placenta weights are more predictive of sensory block level than SPF values in parturients receiving spinal anesthesia.

Günüşen et al. (2019) conducted an observational in Pregnancy requiring cesarean section under spinal anesthesia (n=125). Symphysis pubis-xiphoid distance (SPX) and combined newborn and placenta weights was evaluated on Sensory block level, ephedrine dose, and incidence of hypotension (p=<0.05). Greater symphysis pubis-xiphoid distance and combined newborn and placenta weights were significantly correlated with higher sensory block levels and increased incidence of hypotension (P < 0.05).
