Objective: In part I, measure the EC50 of sufentanil in obese and non-obese parturients combined with 0.1% ropivacaine and compare the differences. Similarly, in part II, measure the EC50 of ropivacaine in obese and non-obese parturients combined with 0.

Epidural anesthesia, being the most commonly used method for labor analgesia in clinical practice, has significantly reduced the pain experienced by parturients during childbirth and decreased the cesarean delivery rate. However, due to the anatomical and physiological differences between obese and non-obese parturients, the effectiveness and techniques of labor analgesia may vary.

In this study, NiCoVO@NC microspheres featuring a yolk-double shell structure were successfully synthesized via ion exchange reactions and surface deposition techniques, employing metal glycerolate as a template. Owing to the bimetallic cobalt-nickel synergistic effect and the N-doped carbon network, this configuration not only optimizes the pore structure but also enhances conductivity, thereby augmenting the stability of the overall structure.

The synthesized SAP (cellulose-g-PAMPS) was characterized by FTIR, TGA, SEM, H NMR, C NMR and XRD. The water absorption equilibrium of cellulose-g-PAMPS could be achieved within 10 min in distilled water.
