Effect of Intra-abdominal Pressure to the Level of the Sensory Block at Caesarean Section Under Spinal Anesthesia

Effect of Intra-abdominal Pressure to the Level of the Sensory Block at Caesarean Section Under Spinal Anesthesia

It is known that an increase in intra-abdominal pressure (IAP) causes a decrease in the volume of cerebrospinal fluid in the lumbar and lower thoracic region, which may contribute to the development of more high spinal block.

There is a hypothesis, the higher the level of intra-abdominal pressure, the greater the likelihood of developing a high-level (=>Th4) sensor block.
