Society of Cardiovascular Anesthesiologists Clinical Practice Improvement Advisory for Management of Perioperative Bleeding and Hemostasis in Cardiac Surgery Patients.

Bleeding after cardiac surgery is a common and serious complication leading to transfusion of multiple blood products and resulting in increased morbidity and mortality. Despite the publication of numerous guidelines and consensus statements for patient blood management in cardiac surgery, research has revealed that adherence to these guidelines is poor, and as a result, a significant variability in patient transfusion practices among practitioners still remains. In addition, although utilization of point-of-care (POC) coagulation monitors and the use of novel therapeutic strategies for perioperative hemostasis, such as the use of coagulation factor concentrates, have increased significantly over the last decade, they are still not widely available in every institution. Therefore, despite continuous efforts, blood transfusion in cardiac surgery has only modestly declined over the last decade, remaining at ≥50% in high-risk patients. Given these limitations, and in response to new regulatory and legislature requirements, the Society of Cardiovascular Anesthesiologists (SCA) has formed the Blood Conservation in Cardiac Surgery Working Group to organize, summarize, and disseminate the available best-practice knowledge in patient blood management in cardiac surgery. The current publication includes the summary statements and algorithms designed by the working group, after collection and review of the existing guidelines, consensus statements, and recommendations for patient blood management practices in cardiac surgery patients. The overall goal is creating a dynamic resource of easily accessible educational material that will help to increase and improve compliance with the existing evidence-based best practices of patient blood management by cardiac surgery care teams.

[A unique case of pulmonary artery catheter bleeding from the oximetry connection port]. / Caso único de sangramento pela porta de conexão do cateter de artéria pulmonar ao módulo de oximetria.

Pulmonary artery catheter is an invasive monitor usually placed in high-risk cardiac surgical patients to optimize the cardiac functions. We present this case of blood oozing from the oximetry connection port of the pulmonary artery catheter that resulted in the inability to monitor continuous cardiac output requiring replacement of the catheter. The cause of this abnormal bleeding was later confirmed to be due to a manufacturing defect.

Bilateral transversus abdominis plane block does not decrease postoperative pain after laparoscopic cholecystectomy when compared with local anesthetic infiltration of trocar insertion sites.

BACKGROUND AND OBJECTIVES: Transversus abdominis plane (TAP) block has been shown to reduce pain and analgesic requirements after abdominal surgery. Our hypothesis was that bilateral TAP blocks decrease pain after laparoscopic cholecystectomy when compared with local anesthetic infiltration of trocar insertion sites. METHODS: Eighty patients undergoing laparoscopic cholecystectomy were randomized to receive either bilateral TAP blocks or local anesthetic infiltration of trocar insertion sites with ropivacaine 0.5%. Postoperative pain scores and analgesic use for the first 24 hrs were recorded. RESULTS: Eighty patients were enrolled in the study. After exclusions, data were analyzed on 39 patients in group T (bilateral TAP block) and 35 patients in group I (infiltration). There was no statistically significant difference in pain scores on the numeric analog scale (0-10) between the groups at 4 hrs after surgery (P = 0.18) or during the 24 hrs after surgery (P = 0.23). The time interval from anesthesia start to surgery start was greater in group T than group I (48 vs 35 mins, P < 0.001). There was no significant difference found in analgesic use during the first 24 hrs after surgery. CONCLUSIONS: Bilateral ultrasound-guided TAP block is equivalent to local anesthetic infiltration of trocar insertion sites for overall postoperative pain in a heterogeneous group of patients undergoing laparoscopic cholecystectomy.

O cateter de artéria pulmonar é um monitor invasivo geralmente usado durante cirurgias cardíacas em pacientes de alto risco para aprimorar as funções cardíacas. Apresen-tamos o caso de escoamento de sangue pela porta de conexão do cateter de artéria pulmonar para oximetria que resultou na impossibilidade de monitorar o débito cardíaco contínuo e na substituição do cateter. A causa do sangramento anormal foi posteriormente confirmada como um defeito de fabricação.

El catéter de arteria pulmonar es un monitor invasivo generalmente usado durante cirugías cardíacas en pacientes de alto riesgo para optimizar las funciones cardíacas. Presen-tamos el caso de entrada de sangre por el puerto de conexión del catéter de arteria pulmonar para oximetría, trayendo como resultado la imposibilidad de monitorizar el gasto cardíaco continuo y, por ende, la sustitución del catéter. La causa del sangrado anormal fue posteriormente confirmada como un defecto de fabricación.
