A Low-dose human fibrinogen is not effective in decreasing postoperative bleeding and transfusion requirements during cardiac surgery in case of concomitant clinical bleeding and low FIBTEM values: A retrospective matched study.

Background: Studies evaluating the hemostatic effects of fibrinogen administration in cardiac surgery are not conclusive.

Aims: We investigated whether the use of a low-dose human fibrinogen in case of clinical bleeding after protamine administration and concomitant low FIBTEM values is effective in reducing postoperative bleeding. Secondary end-point was to investigate the consumption of allogeneic blood products.

Comparison of stroke volume (SV) and stroke volume respiratory variation (SVV) measured by the axillary artery pulse-contour method and by aortic Doppler echocardiography in patients undergoing aortic surgery.

Background: The goal of the study was to compare stroke volume (SV) and respiratory stroke volume variation (SVV) measured by pulse-contour analysis and aortic Doppler.

Methods: These were measured by pulse-contour analysis and thermodilution (PiCCO) and by aortic pulsed wave Doppler with transoesophageal echocardiography in patients undergoing abdominal aortic surgery. Simultaneous measurements were done at different times of surgery.

Pain relief after arthroscopic shoulder surgery: a comparison of intraarticular analgesia, suprascapular nerve block, and interscalene brachial plexus block.

In this prospective, randomized, blinded study, we assessed the analgesic efficacy of interscalene brachial plexus block (ISB), suprascapular nerve block (SSB), and intraarticular local anesthetic (IA) after arthroscopic acromioplasty. One-hundred-twenty patients were divided into 4 groups of 30. In Group SSB, the block was performed with 10 mL of 0.
