Safety of spinal anesthesia in pregnant vaccinated with one or two doses of the BNT162b2 vaccine: A retrospective observational cohort study.

Purpose: To evaluate the safety of spinal anesthesia in pregnant women who underwent cesarean section during the Covid-19 pandemia and were immunized with the BNT162b2 vaccine.

Methods: Historical cohort study that included three groups: non-vaccinated pregnant with no history of acute or previous Covid-19 [NV ( = 70)], vaccinated with one dose [1D ( = 65)] or two doses of BNT162b2 [2D ( = 45)], who underwent cesarean section with spinal anesthesia. Variables with normal distribution were analyzed with ANOVA.

Pseudothrombocytopenia in a patient undergoing splenectomy of an accessory spleen. Case report.

Background And Objectives: Coagulation tests (CBC and prothrombin time) were initially conceived as a mean of screening and following rare congenital coagulopathies; the CBC provides the number of platelets per cubic milliliter. The objective of this report was to present the case of a patient who presented with an extremely low number of platelets when her blood was analyzed in an EDTA-containing tube and its numbers were normal when the blood was analyzed with citrate, alerting for the risk of erroneously administering blood products.

Case Report: This is the case of a 40-year-old female patient, ASA II.
