Risk Factors for Surgical Site Infections in Patients Undergoing Emergency Surgery: A Single-centre Experience.

BACKGROUND/AIM: Surgical site infections (SSI) are associated with increased morbidity and mortality, and they occur more frequently during unplanned emergency surgical (ES) procedures rather than elective. Our aim was to determine the incidence of SSI within our ES cohort and to identify risk factors for SSI. PATIENTS AND METHODS: Data from consecutive patients undergoing ES in a single institution during a 5-year period were prospectively collected and analyzed. RESULTS: A total of 838 consecutive patients were included. The median age was 52 (IQR=25-71) years and some 368 (44%) were female. 157 (18.7%) of those patients developed SSI. The most commonly isolated pathogen was E. Coli (55.4%) followed by Staphylococcus Aureus (40.1%). The 30-day mortality rate of patients who presented SSIs was 14.6% compared to 6.8% of patients without SSI (p=0.002). Multivariable analysis showed that the type of wound, American Society of Anesthesiology score, severity and duration of surgery >90 min were independent risk factors for the occurrence of SSI. CONCLUSION: Identification of modifiable causative factors for SSI within an ES unit is paramount as they can critically impact postoperative outcomes.

Management of blunt hepatic and splenic injuries (grade ≤ III) in patients receiving antithrombotic therapy.

BACKGROUND: Non-operative management (NOM) may be particularly challenging in patients receiving synchronous antithrombotic therapy (AT). The current study examined the feasibility of NOM in patients under AT who sustained blunt splenic or hepatic injuries. METHODS: We analyzed the results of a 5-year (2010-2014) pre-decided treatment protocol, including 15 patients under AT who were treated for splenic and/or hepatic injuries at our institution. The antithrombotic therapy consisted of acenocoumarol 4 mg, acetylsalicylic acid 100 mg and clopidogrel 75 mg. Vitamin K (Vit K), Fresh frozen plasma (FFP) and Prothrombin Complex Concentrate (PCC) were transfused to patients receiving anticoagulant therapy, while platelets (PLTs) were given to patients under antiplatelet therapy if their level was excessively low. The organ injury grading scale, injury severity score (ISS), the need for blood transfusion and intensive care unit (ICU)/ high dependency unit (HDU) admission, morbidity, mortality and duration of hospital stay were also recorded. RESULTS: Ten patients fulfilled the criteria for NOM and were treated accordingly. No conversion to operative management (OM) was required (success rate 100%). Five patients were managed surgically due to hemodynamic instability and/or signs of peritonitis. Reversal of AT was attempted in all cases. CONCLUSIONS: Hemodynamically stable patients under AT with blunt hepatic or splenic injuries (grade ≤ III) and no signs of peritonitis, may be good candidates for NOM, despite their bleeding tendency. The type of AT does not seem to influence the final outcome. Reversal of AT should be stratified individually. KEY WORDS: Antithrombotic therapy, Hemodynamic stability, Non-operative management.
