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

研究组 & 干预措施
Measurement of IAP
The data obtained are in inches of water column were translated in millimeters of mercury.
干预措施: Measurement of IAP (Procedure)
结局指标
主要结局
Classification Grade of Intra-abdominal Hypertension (IAH)
时间窗: Before spinal anesthesia, average 10 minutes.
Average IAP in pregnant women with different Grade of intra-abdominal hypertension Physiological norm (≤11,99 mm Hg) Grade I (12 - 15.99 mm Hg) Grade II (16 - 20.99 mm Hg) Grade III (21 - 25.99 mm Hg)
The Level of Intra-abdominal Pressure (IAP)
时间窗: Before spinal anesthesia, average 10 minutes.
Measurement of IAP: The level of intra-abdominal pressure was measured via a Foley catheter through the urinary bladder. After the introduction of a 30 mL of warm saline. Measurement of the water column in the system was made from the zero level to the mid-axillary line, after quiet breathing pregnant at the time of expiration. The data obtained are in inches of water column were translated in millimeters of mercury.
Obesity and IAP
时间窗: Before spinal anesthesia, average 10 minutes.
Effect of obesity on the level of IAP
次要结局
- Level of Sensory Blocks(After spinal anesthesia, average 20 minutes.)
- The Level of IAP(After spinal anesthesia, average 20 minutes.)
- Number of Pregnants With Blocks = > Th4 With IAP Higher or Less Than 16 mm Hg(After spinal anesthesia, average 20 minutes.)
