Usefullness of Peri-operative Tranexamic Acid in Primary Breast Augmentation With Implants.

A total of forty participants were included in this case-control study over a fifteen months period. The participants were divided in two equal groups. The case group (TXA group) was treated with a daily oral administration of two grams of tranexamic acid whereas the control group (noTXA group) was not treated. The data that has been recorded is the gender, the age, the implant volume (cc), the shape of the implant (round or anatomical), the type of surgical pocket (pre-muscular or retro-muscular), the texture of the implant (textured or smooth), the operating time (in minutes), the blood pressure operative average during surgery, volume of fluid daily (right and left) and complications (hematoma, infection, deep vein thrombosis, pulmonary embolism, anaphylaxis and early exposure to implants).

Three investigators were enrolled in the study, including the corresponding author. Two investigators performed the intervention, operating one breast each.

At the end of the surgical procedure, a drain was put in the retro-pectoral space on each breast side. A compressive garment was immediately fitted before the exit of the participant. The participants received oral analgesics according to the hospital guidelines and no thromboprophylaxis was given, as it is a standard recommendation of the French Society of Anaesthesiologists (SFAR).

Oral administration of the TXA had never been tested in breast augmentation indications, and the investigators followed the recommendations of one gram, two times a day, starting at the end of the surgery so as to avoid any adverse effects. The participants received two grams of Spotof ® (C.C.D laboratory, Portugal) as an oral liquid solution during three days.

All participants were interviewed by a nurse every four hours starting at the end of the post-operative recovery room till the exit of their hospital stay. Drain fluid volume in the vacuum devices was recorded every twenty four hours. The drains were removed when production was below forty milliliter per twenty four hours, according to hospital routine. Any early (less than seven days) or late (better than thirty days) post-operative complications were also listed. All participants had a consultation seven days and two months after the surgery according to the department guidelines. A hotline telephone number has been given to participants to facilitate contact if any inconvenient consequences have occurred.

In each sub-group (no TXA and TXA), the main outcome was the drain fluid production during the study which was registered for each breast every twenty four hours after the surgery and at the exit of the participant. Volume were stored and collected in milli-liters (mL) without consistency or color analysis. The age (in years), the implant volume (in milliliters), the shape (round or anatomic) and the texture (smooth or textured), the mean operative time (in minutes), the mean operative arterial pressure (in mmHg) were also recorded as well as the length of the hospital stay (in days). Any surgical complications and any side effects associated to the TXA drug were also listed.
