Prevention of excessive blood loss during surgery is important for preserving a patient’s oxygen-carrying capacity. However, maintaining meticulous hemostasis during surgery is necessary for other important reasons.
One is the decreased visibility that uncontrolled bleeding creates. Even high-volume suctioning cannot keep a surgical field completely dry, particularly in the wellvascularized oral and maxillofacial regions. Another problem bleeding causes is’ the formation of hematomas. Hematomas place pressure on wounds, decreasing vascularity; they increase tension on the wound edge and they act as culture media, potentiating the development of a wound infection.
