Rev Clin Inst Matern Lisboa, ; Table III shows the mean values of the parameters evaluated in all three groups throughout the study. Pregnant women, who demonstrate important boqueo, can in theory benefit from this effect during labor.

Role of epidural and general anesthesia. Br J Anaesth, ; The study protocol was approved by the Ethics Commission and all patients signed an informed consent.

Anaesth Intensive Care. Se recomienda el uso de agujas de bisel corto. How to cite this article. Anesthesia and surgical intervention also affect coagulation. This study evaluated, in all three groups, which of the two factors affected coagulation.

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, 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. Labor was the fundamental difference between this group and the other two.

Alpha angle and maximum amplitude: 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. 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 undergoing epidural, subarachnoid, or pudendal nerve block. Fibrinogen levels were similar in all three groups, with a significant reduction after labor M 2 and an increase after 24 hours, but those changes were not clinically significant.


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 Prothrombin and thrombin times behaved similarly in all three groups, increasing after labor M 2.

Gynecol Obstet Invest, ; 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 In non-obstetric populations, surgeries performed under spinal block have a lower incidence of thromboembolic events 12,18,19, N Engl J Med, ; The objective of this study was to determine the effects of regional block on coagulation of pregnant women.

Am J Obstet Gynecol, ; This observation is in accordance with that of several authors who reported that thromboelastography is more sensitive and provides faster results in clinical and surgical settings that require repeated measurements to evaluate changes in coagulation dynamics Rev Pudendoo Anestesiol, ; Therefore, it is possible that this ppudendo of patients experienced above average blood loss.

Patients were divided in three groups: 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.

Normal pregnancy causes changes in coagulation that lead to a hypercoagulable state. Pdendo J Obstet Gynecol, ; 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.

Several authors observed the inhibitory action of local anesthetics on coagulation and the inhibitory action of epidural anesthesia on platelet aggregation Besides, routine laboratorial tests do not contribute puudendo elucidate this question, since they do not report the level of activity of coagulation factors, only their plasma levels.

Hemoglobin and hematocrit levels were included in this study to rule out the influence of hemodilution on coagulation factors. Although significant, those results have no clinical implications. PD and SA groups did not show statistically significant differences throughout the study.

We did not find in the bloquueo any reports on the profile of aPTT in pregnant women during or after anesthesia. It is possible that, in the present study, the slight increase detected was an expression of the increased consumption of coagulation factors that begins after expulsion of the placenta, during hemostasis of the surface of the uterus In the BP group, the evaluation was done before the blockade, after delivery, and 24 hours after the blockade.

Niccolai bW. It is known that reduced levels of those factors secondary to hemodilution can affect coagulation Parameters were analyzed in the following moments: Pre-anesthetic medication was not administered.

There was a Analysis of the three groups, subjected to different anesthetic techniques, demonstrated a variation in blpqueo at different moments only in the BP group.
