Intra-Abdominal Pressure and Post-Spinal Hypotension in Cesarean Delivery, 83 Patients

A prospective observational study of 83 parturients undergoing elective cesarean delivery under spinal anesthesia, authored by Rui Ma and last updated in April 2026. The data investigates the association between preanesthetic intra-abdominal pressure and the risk of post-spinal hypotension. Results include risk ratios and exploratory receiver operating characteristic analysis.

Use Cases

• Predicting post-spinal hypotension risk based on intra-abdominal pressure measurements.
• Evaluating the discriminatory performance of a clinical threshold (e.g., 12.5 mmHg) for identifying high-risk patients.
• Building models adjusted for body mass index to assess the robustness of the pressure-hypotension association.

Strengths

• Includes data from 83 parturients for a specific clinical scenario.
• Provides specific statistical results: an adjusted relative risk of 2.88 per 5-mmHg IAP increase and an AUC of 0.92.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small at 16.6 KB, indicating limited scope.
• The exploratory IAP cutoff is described as unstable, ranging from 12.5 to 13.5 mmHg.
