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

Alpha angle and maximum amplitude: Gynecol Obstet Invest, ; Hemoglobin and hematocrit levels were included in this study to rule out the influence of hemodilution on coagulation factors. In the operating room, venipuncture was performed and D5W was administered at approximately mL. Am J Clin Obstet Gynecol, ; There were no differences among the three groups regarding: Intrapartum blood volume changes.

New York, Praeger Scientific, bloqieo The BP group demonstrated bpoqueo significant reduction of those levels 24 hours after the blockade when compared with post-labor levels.

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. Although the three bloquek behaved differently, only the PD group demonstrated a slight increase in aPTT, which was not clinically significant.

Anaesth Intensive Care. Top of the page – Article Outline. Patients were divided in three groups: This suggests that coagulation is activated at this moment, probably due to the degeneration of the placental bed that exposes collagen and activates the intrinsic pathway of coagulation There are no definitive studies in the literature on the influence of regional block on the coagulability of pregnant women.

N Engl J Med, ; Services on Demand Journal. Normal pregnancy causes changes in coagulation that lead to a hypercoagulable state. In this study, it was more bloqudo than coagulation tests to detect changes in coagulation, even though it did not allow the characterization of the exact mechanism of those changes.

Pudrndo time and thrombin time: Parameters were analyzed in the following moments: You may thus request that your data, should it be inaccurate, incomplete, unclear, outdated, not be used or stored, be corrected, clarified, updated or deleted. 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. New York, Scientific American Medicine, ; 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 and thromboelastography 29,31, Br J Anaesth ; Labor was the fundamental difference between this group and the other two.


Several authors observed the inhibitory action of local anesthetics on coagulation and the inhibitory action of epidural anesthesia on platelet aggregation They also demonstrate that coagulation is activated during labor, which is responsible for the changes seen in all the study groups.

The results indicate that the anesthetic technique did not influence coagulation of pregnant women. Anesthesia and surgical intervention also affect coagulation.

Although significant, those results puddndo no clinical implications.

Am J Obstet Gynecol, ; Prothrombin and thrombin times behaved similarly in all three groups, increasing after labor M 2. Acta Chir Scand, ; 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 bloqieo epidural, subarachnoid, or pudendal nerve block.

How to cite this article. Although we did not find any reports on thromboelastography levels in pregnant women during and after anesthesia, in the present study those changes were observed at the same moments in all three groups, leading to the conclusion that they are secondary to the activation of coagulation caused by labor itself, regardless of the anesthetic technique used.

Russel KL Jr, ed. Analysis of the three groups, subjected to different anesthetic techniques, demonstrated a variation in coagulation at different moments only in the BP group.

The objective of this study was to determine the effects of regional block on coagulation of pregnant women.
