INTRODUCTION: It is common knowledge that an increase of intra-abdomninal pressure ( @entity3813 ) 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 currently no research devoted to studying the impact of intra-abdominal pressure in pregnancy on the development of high spinal blockade. GOAL OF THE STUDY: To investigate effects of intra-abdominal pressure in pregnancy on the development of spinal blockade and incidence of @entity551 during cesarean section. MATERIAL AND METHODS: 170 pregnant @entity1 with gestational age 38-40 weeks were included in the randomized, blinded, controlled study. All the @entity1 received elective cesarean section under spinal anesthesia (SA). Pregnant @entity1 w ,ere divided into two groups of 85 females each. In the first group, the anesthesiologist did not know the value of @entity3813 and used the dose of local anesthetic focusing on height, weight, and according to his own experience. In the second group, an anesthesiologist corrected dose of local anesthetic depending on the @entity3813 and also considered the height and weight of a @entity1 . RESULTS: In 9.2% of @entity1 , @entity3813 was less than 11 mmHg (physiologically normal), in 49%--from 12 to 15 mmHg (degree I of @entity8479 ( @entity8479 )), in 40.3%--from 16 to 20 mmHg (degree II of @entity8479 ), in 1.5%--from 21 to 25 mmHg (degree III of @entity8479 ). In the first group, the incidence of high spinal block (above Th4) and incidence of @entity551 (systolic blood pressure under 90 mm.Hg) was two times higher than in the second group (p<0.01). CONCLUSIONS: @entity8479 in pregnant @entity1 contributed to the development of high spinal block and @entity551 . To prevent these complications, we recommend decreasing the dose of local anesthetic with use of the Scale of the Risk of developing high spinal block in pregnant.
