Non-invasive Perioperative Hb Monitoring in Spinal Surgery
Blood LossSurgicalThe decision to transfuse or not to transfuse blood products is one of the main issues in patients undergoing surgery. The standard laboratory method of hemoglobin assessment is time-consuming, gives intermittent data, and requires venipuncture which is invasive and painful. In the past decade, the use of non-invasive and faster methods, which allow physicians to measure hemoglobin levels at the patient's bedside, have become widespread. One of the tools that make this possible is Spectrophotometric Hemoglobin. However, one of the main concerns regarding this method is its accuracy. Since the accuracy of this assessment depends on the extent of perfusion of the organ on which the probe is placed, use of digital nerve blocks proposed to increase its accuracy. This study aims to evaluate the effects of digital nerve block (with bupivacaine) on the accuracy of non-invasive hemoglobin monitoring by spectrophotometry in patients undergoing spinal surgery.

BleedingSurgical Blood LossThe aim is to conduct a double-blinded single-centre randomized controlled clinical trial of application of topical dose of tranexamic acid (TA) versus the usual intravenous TA in patients undergoing cardiac surgery at the Hamilton General Hospital. This pilot study will assess the feasibility to perform a large randomized international trial exploring this objective.
ROTEM-guided Transfusion Protocol in Attempt to Reduce Blood Transfusions in Major Oncological Surgery...
Blood LossSurgical2 moreNeed for perioperative blood transfusion is still high in certain types of oncological abdominal surgery. Allogeneic blood transfusion may be detrimental in cancer patients undergoing a potentially curative resection of malignant tumor, although the detailed mechanism of this effect is still under debate. We plan to evaluate whether a new, rotational thromboelastography-guided algorithm (ROTEM) to guide hemostatic resuscitation intra-operatively decreases the use of allogeneic blood products, the total amount of bleeding, transfusion related side effects, thromboembolic complications and costs. Its effect on each patient's post-operative hemostatic profile is also measured. 60 patients having a potentially curative pancreaticoduodenectomy (or resection of cauda of pancreas), total removal or partial resection of kidney and open radical cystectomy are recruited when an active blood loss of more than 1500 ml is estimated and/or measured and are randomized into two groups: one will be treated conventionally, ie. using massive transfusion protocol (MTP) if necessary, clinical judgement and conventional coagulation tests, the other treated using a ROTEM-based algorithm.

Effect of Equal Ratio Ventilation on Blood Loss During Posterior Lumbar Interbody Fusion Surgery...
Blood LossSurgicalVentilator mode change was associated with decrease in blood loss during posterior lumbar interbody fusion (PLIF) due to decrease in the peak inspiratory pressure (PIP). The purpose of this study was to determine the effect of equal ratio ventilation (ERV), which sets the I:E ratio of the ventilator to 1:1 during volume controlled ventilaiton, on surgical blood loss during PLIF. Investigators hypothesized that ERV would decrease surgical blood loss due to decrease in the PIP.
Mechanical Dilatation of the Cervix at Elective Caesarean Section to Reduce Post-Operative Blood...
Post Operative Hemorrhageobstetric hemorrhage remains one of the major causes of maternal death in both developed and developing countries. Because of its importance as a leading cause of maternal mortality and morbidity, and because of evidence of substandard care in the majority of fatal cases, obstetric hemorrhage must be considered as a priority topic for national guideline development. Some obstetricians believe that the cervix of women at non-labor cesarean section is undilated and might cause obstruction of blood or lochia drainage, leading to postpartum hemorrhage and endometritis from the collection of lochia or debris. Dilatation of the cervix helps with the drainage of blood during postpartum, reducing intrauterine infection or the risk of postpartum hemorrhage. To avoid this problem, some obstetricians routinely dilate the cervix from above during an elective/ non-labor cesarean section using finger, sponge forceps or other instruments
