Prevalence of the systemic inflammatory response syndrome in patients who underwent orthognathic surgery

The systemic inflammatory response syndrome (SIRS) is the body's response to an insult, such as infection, trauma, burn, and surgical stress linked to several factors deemed potential for multiple organ failure if left untreated. Thus, the aim of this paper was a prospective study to examine the incidence of SIRS in postoperative patients who underwent orthognathic surgery from June/2013 to July/2016.

The sample consisted of 80 patients who underwent bimaxillary orthognathic surgery, with data on vital signs and white blood cell count collected preoperatively, and the same data collected in the immediate postoperative period, in addition to CO₂ pressure in arterial blood by blood gas analysis. The data were tabulated and cases of SIRS (2 or more signs out of four pre-set signs) were identified within 24 h after surgery.

From the sample of 80 patients, 26 (32.5% of total) patients had SIRS with higher incidence in females who are 40 years old.

The incidence of patients who develop SIRS after orthognathic surgery is relatively high and we should pay attention to the possible complications that these cases can evolve.
