Alpha angle and maximum amplitude: There are no definitive studies in the literature on the influence of regional block on the coagulability of pregnant women. The owners of this website hereby guarantee to respect the legal confidentiality conditions, applicable in France, and not to disclose this data to third parties.

Although it was not the objective of this study, the usefulness of thromboelastography on the dynamic evaluation of the coagulation profile, especially as a marker of coagulability in populations at risk, should be noted. Personal information regarding our website’s visitors, including their identity, is confidential. It is interesting to note that, when the BP group was excluded from the statistical analysis, PD and SA groups did not demonstrate variation at the different moments.

Am J Clin Pathol, ; The objectives of this study were to establish the coagulation profile and pudendp the influence of regional block on said profile in pregnant pudsndo in labor and in those undergoing cesarean section, using thromboelastography and routine tests coagulation tests, fibrinogen. Br J Anaesth, ; Coagulation was assessed, in all three groups, through the following tests: There were no differences among the three groups regarding: Role of epidural and general anesthesia.

Therefore, it is possible that this group of patients experienced above average blood loss. Outline Masquer le plan. The significant reduction in postoperative thromboembolic complications has been attributed to the use of regional block, probably due to attenuation of the neuroendocrine-metabolic response.

Prothrombin time and thrombin time: Acta Chir Scand, ; Analysis of the three groups, subjected to different anesthetic techniques, demonstrated a variation in coagulation at different moments only in the BP group. Br J Obstet Gynecol, ; In the operating room, venipuncture was performed and D5W was administered at approximately mL.


Thirty patients in the 3 rd trimester were enrolled; ten patients underwent epidural block for cesarean section with mg of 0. Pre-anesthetic medication was not administered. In this study, it was more reliable than coagulation tests to detect changes in coagulation, even though it did not allow the characterization of the exact mechanism of those changes.

Anesthesiology, ;55 Suppl 3A: Table III shows the mean values of the parameters evaluated in all three groups throughout the study.

Effects of pudendal nerve, epidural and subarachnoid block on coagulation of pregnant women

Labor was the fundamental difference between this group and the other two. In the present study, the spinal block was not responsible for important changes in the coagulation profile.

How to cite this article. Blood samples were scheduled to be drawn during the period of maximal intensity of the sympathetic blockade and during the peak plasma level of the local anesthetic 23, Pregnant women, who demonstrate important pudenco, can in theory benefit from this effect during labor.

Comparing the different moments, an increase in TT and PT from M 0 to M 2 was observed, followed by a reduction and return to baseline values. pudedno

It should be noted that blood loss was greater in the BP group, as indicated by the concentration of hemoglobin and hematocrit, which might have influenced the results.

There was a Although significant, those results have no clinical implications. This allowed us to conclude that once labor is initiated, it imposes subclinical changes in coagulation, detected by thromboelastography, lasting at least 24 hours after delivery. Although we did not find any reports on updendo levels in pregnant women during and after anesthesia, in the present study those changes were observed at the same moments in all three booqueo, leading to the conclusion that they are secondary to the activation of coagulation caused by labor itself, regardless of the anesthetic technique used.

The results indicate that the anesthetic technique did not influence coagulation of pregnant women. Am J Clin Obstet Gynecol, ; In patients undergoing general anesthesia, it was observed a tendency to develop a hypercoagulable state, reduction in fibrinolysis, inhibition of platelet aggregation caused by inhalational agents and an increase in the total number of platelets The study protocol was approved by the Ethics Commission and all patients signed an informed consent.


Besides, routine laboratorial tests do not contribute to elucidate this question, since they do not report the level of activity of coagulation factors, only their plasma levels.

Hemoglobin and hematocrit levels pudenvo included in this study to rule out the influence of hemodilution on coagulation factors. In the conditions of the present study, the sympathetic blockade and the local anesthetic did not have any influence on the coagulation of pregnant women at term bloquep epidural, subarachnoid, or pudendal nerve block. Several authors observed the inhibitory action of local anesthetics on coagulation and the inhibitory action of epidural anesthesia on platelet aggregation J Pharmacol Exp Ther, ; It is not known whether the spinal block affects coagulation through the sympathetic blockade it induces or through the plasma levels of the local anesthetic Anaesth Intensive Care.

It is known that coagulation is activated after delivery of the fetus, and this is related with uterine contraction during expulsion, reaching maximal activation during the separation of the placenta, which was confirmed by coagulation tests pudrndo thromboelastography 29,31, Studies comparing general anesthesia to epidural block demonstrated the presence of a postoperative hypercoagulable state in patients phdendo general anesthesia, with a greater incidence of thromboembolic events You may thus request that your data, should it be inaccurate, incomplete, unclear, outdated, not be used or stored, be corrected, clarified, updated or deleted.

They also demonstrate that coagulation is activated during labor, which is responsible puddendo the changes seen in all the study groups. Theissen aP. In the BP group, the evaluation was done before the blockade, after delivery, and 24 hours after the blockade.

It is known that reduced levels of those factors secondary to hemodilution can affect coagulation
