With transverse diameter measurement of the RIGHT main femoral veinpredictivity of postspinal hypotension evaluation

The most common major abdominal surgery in the world is cesarean section. It refers to the removal of the fetus, placenta and membranes by making an abdominal and uterine incision. In cesarean section, spinal anesthesia method, which carries less risk for mother and fetus, is preferred. Spinal anesthesia is the standard method for elective cesarean section. Hypotension after spinal anesthesia; occurs in more than half of the cases. Hypotension due to spinal anesthesia, maternal nausea, vomiting, dyspnea, headache; can lead to adverse maternal and infant outcomes such as fetal acidosis and a low APGAR score. Therefore, being able to predict hypotension is of clinical importance. The aim of our study was to test the predictability of the development of postspinal hypotension with the sonographic evaluation of RCFV before cesarean section. We aimed to avoid bad maternal and fetal outcomes by predicting postspinal hypotension. The study was designed as prospective and cross-sectional. Since the study was designed as a study evaluating the relationship between data collection and complications, there was no control arm. The study included 82 pregnant women who were hospitalized at the Tokat Gaziosmanpaşa University Gynecology and Obstetrics Clinic for delivery at 37 weeks and above and who were going to give birth by cesarean section. A decrease of 20% or more from the initial blood pressure value was accepted as a criterion for hypotension after spinal anesthesia. Perop and postoperative first 48 hours maternal nausea, vomiting, and headache complaints were questioned and recorded. In addition, fetal APGAR scores and blood gas pH value studied from fetal cord blood were recorded. As a result; while hypotension was observed after spinal anesthesia in patients with RCFV diameter of 10.57±2.42 mm and a flow rate of 9.39±5.61 mm/sec; hypotension was not observed in patients with an RCFV diameter of 9.32±1.98 mm and a flow rate of 13.72±9.82 mm/sec. Thus, it is possible to conclude that postspinal hypotension can be predicted and poor fetomaternal outcomes can be avoided by measuring RCFV diameter and flow velocity.
