METHOD FOR SPINAL ANAESTHESIA IN PREGNANT WOMEN SUFFERING CONCOMITANT CARDIOVASCULAR PATHOLOGY Russian patent published in 2015 - IPC A61M19/00 A61M25/01 A61K31/16 A61K33/14 A61P23/02 

FIELD: medicine.

SUBSTANCE: spinal anaesthesia is followed by catheterisation of an epidural space at the level of L1-L2. The spinal anaesthesia is performed at the level of L4-L5 by administering 0.5% bupivacaine. Bupivacaine is administered in a dose of 5-6 mg if the pregnant woman's height is less than 165 cm, and the dose is 6-7 mg if the pregnant woman is from 165 to 175 cm high. After the local anaesthetic is administered into the epidural space, normal saline is introduced. If the intra-abdominal pressure is ≤16 cm H₂O, normal saline 15 ml is administered; if the intra-abdominal pressure is 17-21 cm H₂O, an amount of normal saline is 10 ml, whereas the intra-abdominal pressure of 22-28 cm H₂O requires an amount of 5 ml.

EFFECT: performing the effective spinal anaesthesia combined with reducing a probability of hypertension by dilating the epidural space preliminary in accordance with the intra-abdominal pressure.
