Investigating the Effect of Fibrinogen Injection on Bleeding in Coronary Artery Bypass Surgery: A Clinical Trial.

Background: Prevention and optimal treatment of postoperative bleeding are of great clinical importance in various types of surgeries including coronary artery bypass graft (CABG). Reducing the amount of bleeding will reduce the complications subsequent to blood transfusion. The positive effects of coagulation factors, especially fibrinogen, after cardiovascular bypass could have beneficial effects due to reduced bleeding and less need for blood transfusion.

The Effect of Fibrinogen on Blood Loss After Lumbar Surgery: A Double-Blind Randomized Clinical Trial.

Background: Spinal surgeries often have a high risk of hemorrhage during and after surgery, thus most patients require blood transfusions and blood products. Fibrinogen is used in different forms to control hemorrhage.

Objectives: The present study aimed to evaluate the outcomes of prophylactic fibrinogen administration in reducing hemorrhage after lumbar surgery.

A Comparative Study of the Amount of Bleeding and Hemodynamic Changes between Dexmedetomidine Infusion and Remifentanil Infusion for Controlled Hypotensive Anesthesia in Lumbar Discopathy Surgery: A Double-Blind, Randomized, Clinical Trial.

Background: The aim of this study was to compare the volume of blood loss and hemodynamic changes in patients undergoing lumbar discopathy, after continuous infusions of dexmedetomidine versus remifentanil during anesthesia with controlled low blood pressure.

Methods: In this randomized double-blind clinical trial, 60 patients aged 20 to 65 years were randomly assigned to control and intervention groups. The intervention group received a continuous infusion of dexmedetomidine at 0.

Effect of Remote Ischemic Preconditioning on Troponin I in CABG.

Background: Elective open heart surgery is associated with troponin release in some cases due to myocyte necrosis.

Objectives: The aim of this study was to measure cardiac troponin I (cTnI) preoperatively in elective CABG after remote ischemic preconditioning.

Methods: Twenty-eight patients were selected for elective CABG.

Is presence of bacteria in preoperative microscopic urinalysis of the patients scheduled for cardiac surgery a reason for cancellation of elective operation?

Background: In some hospitals, urinalysis is done routinely for all patients scheduled for cardiac surgery. Occasionally pyuria or bacteria is reported in the microscopic urinalysis of these patients that are clinically asymptomatic for urinary tract infections.

Objectives: WE WERE SEEKING ANSWER TO THIS QUESTION: is the presence of a different number of bacteria in preoperative microscopic urinalysis of asymptomatic patients scheduled for cardiac surgery indicative of potential postoperative complications and as a result, a good reason to postpone the operation?

Patients And Methods: We conducted a retrospective cross-sectional study based on the review of the medical records of 1165 patients who underwent open-heart surgery.
