The Effect of Topical Administration of Common Drugs on Postoperative Bleeding and Pain

PainPostoperative1 more

After surgical procedures, interventions to reduce postoperative pain and bleeding are of great importance. In this study, the effect will be investigated of smearing common drugs, which are designed for injection, directly onto the raw wound surface (topical application) created during surgery. Topical application allows a small amount of drug to reach a large wound area, higher drug concentration in the exposed wound surface but very low concentration in the body, and no risk of injury from needles. Although beneficial effects of such an easy and low-cost intervention would be expected, the investigators have found no previous reports on blinded and controlled studies.

Decreasing Postoperative Blood Loss by Topical vs. Intravenous Tranexamic Acid in Open Cardiac Surgery...

BleedingSurgical Blood Loss

The 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.

Topical Application of Tranexamic Acid to Reduce Post-operative Bleeding in Coronary Artery Bypass...

Coronary Artery Disease

The goal of this project is to determine whether the use of tranexamic acid, a clot-promoting drug, applied topically over the heart in coronary artery bypass graft surgery (CABG) will reduce post operative blood loss. The investigators' hypothesis is that the use of a tranexamic acid-containing cardiac bath prior to chest closure will result in a statistically significant reduction in blood loss and transfusion requirements in patients who undergo CABG.

Mechanical Dilatation of the Cervix at Elective Caesarean Section to Reduce Post-Operative Blood...

Post Operative Hemorrhage

obstetric 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

Effect of Tranexamic Acid on Postoperative Bleeding Following Sinus and Nasal Surgery

Chronic SinusitisNasal Obstruction3 more

The purpose of the research is to assess the effectiveness of a dose of intravenous tranexamic acid (TXA) given intraoperatively to reduce postoperative bleeding after endoscopic sinus or nasal surgery (e.g. septoplasty, endoscopic sinus surgery, turbinate surgery). This medication has been shown to decrease blood loss during this type of surgery, but the implications for bleeding following surgery are unclear. Any impact on postoperative bleeding will be assessed over the first 7 days following surgery leading up to the first scheduled postoperative clinic visit. Patients will keep a standardized daily diary of their bleeding experience by indicating on a 0-10 visual analog scale (VAS) their impression of their bleeding. The primary outcome is the patient-reported visual analog scale (VAS) bleeding score on each day after surgery. The secondary outcomes include the the frequency with which the otolaryngology resident service is requested to evaluate patients in the recovery unit for postoperative bleeding concerns and the frequency of interventions such as application of hemostatic materials, packing, cautery, and/or return to the operating room.

After surgical procedures, interventions to reduce postoperative bleeding are of great importance. In this study, the effect will be investigated of smearing tranexamic acid, which is designed for injection, directly onto the raw wound surface (topical application) created during surgery. Topical application allows a small amount of drug to reach a large wound area, higher drug concentration in the exposed wound surface but very low concentration in the body, and no risk of injury from needles. The researchers have recently shown that topically applicated tranexamic acid reduces bleeding in women who had two-sided breast reduction surgery. Now it will be studied whether topically applicated tranexamic acid reduces bleeding after breast surgery for breast cancer. After surgery for breast cancer patients may also experience problems with long lasting seroma. Therefore it will at the same time be investigated whether topical tranexamic acid reduces the development of seroma in these patients.

Neptune Pad ® Compared to Conventional Manual Compression

Postoperative Hemorrhage

BACKGROUND. Arterial access site complications remain the most frequent adverse events after percutaneous transluminal procedures. We investigated the safety and efficacy of the pro-coagulant wound dressing Neptune Pad ® compared to conventional manual compression for access site management after peripheral percutaneous interventions. METHODS. We enrolled 201 consecutive patients and randomly assigned patients for Neptune Pad ® (n=100) vs. conventional manual compression (n=101). Patients were followed clinically until hospital discharge and by duplex ultrasound at 24 hours postprocedure for occurrence of access site complications. Time-to-hemostasis and time-to-ambulation were recorded, patients´ and physicians´ discomfort were measured using a visual analogue scale.

Hetastarch and Bleeding Complications After Off-Pump Coronary Bypass Surgery

Postoperative Hemorrhage

There has been continuing debate about whether use of hetastarch for volume replacement in coronary artery bypass surgery [CABG] increases the risk of postoperative bleeding. A recent meta-analysis of hetastarch use in on-pump CABG concluded that use of hetastarch in these procedures is associated with increased risk, but the safety of hetastarch use in off-pump procedures remains unresolved. We designed a double-blinded randomized clinical trial to investigate this question. The study was designed as an equivalence trial. Statistical power calculations were performed taking this into consideration. Sealed assignments from a block randomization table developed prior nto initiation of the trial were unsealed in the operating room. These were used to assign patients scheduled for off-pump CABG to receive either 1 L of hetastarch or 1 L of albumin as part of intraoperative volume replacement. Albumin was used for all subsequent intraoperative and postoperative fluid replacement. The rate of postoperative bleeding was assessed prospectively by monitoring hourly chest tube drainage and number of units of blood products transfused postoperatively in the Intensive Care Unit. Risk was assessed by a Data Safety Monitoring Committee (DSMC) established for this trial. The SAMC was scheduled per protocol to meet after the first 15 subjects (both groups combined) had 1000cc or more of chest tube drainage in the first 12 hours postoperative, and then subsequently either after 15 additional bleeds of this volume or following a schedule set at the discretion of the DSMC. The trial was continued until 156 patients had been recruited. At that time, 78 participants each had been assigned to the hetastarch and albumin groups. DSMC review at that time determined that use of hetastarch is associated with a risk of postoperative bleeding which is greater than the risk associated with use of albumin and the DSMC accordingly halted the trial.

The Effect of Tranexamic Acid on Intraoperative and Post-Operative Bleeding in Functional Endoscopic...

Chronic Sinusitis

Sinus surgery is a common, day surgery procedure performed by general and subspecialty trained otolaryngologists. In most cases, this is a safe surgery with a low incidence of complications. When there is significant bleeding or enough bleeding to obscure important anatomical landmarks, there is a higher chance of complications. These complications can include blindness, meningitis or cerebrospinal fluid leak. Our hypothesis is that in patients taking oral tranexamic acid three days before surgery and six days after, there will be less intraoperative bleeding, better surgical visualization and less postoperative bleeding events.
