RESUMO
BACKGROUND: Surgical site infection (SSI) is a well-known complication of general surgery. Although overall SSI rate is relatively low, it is the most common nosocomial infection. SSI adversely affects patient outcomes and healthcare costs. METHODS: Patients who underwent general surgical procedures between 2003 and 2009 were included in the study. SSI diagnosed based on the National Nosocomial Infection Surveillance System (NNIS) criteria. Patients were classified into two groups: SSI (+) and SSI (-). Patient demographics, co-morbidities, procedural details, and SSI type and treatment were evaluated. Multivariate analysis was performed to determine independent risk factors of SSI. RESULTS: In total, 4690 patients were included. Overall SSI rate was 4.09% (192/ 4690). Colorectal surgery was associated with the highest SSI rate (9.43%) followed by pilonidal sinus (8.79%), upper gastrointestinal (GI) (8.09%), hepatobiliary (6.68%), hernia (0.78%), and breast-thyroid (0.3%) surgery. Procedure type (pilonidal sinus, colorectal, hepatobiliary and upper GI surgery), prolonged preoperative hospital stay, higher ASA score, emergency surgery, dirty- infected wound class, experienced surgeon, prolonged operating time, presence of surgical drains, and intraoperative transfusion were determined as independent risk factors of SSI (p 0.05). CONCLUSION: Most of the determined risk factors were surgeon and procedure related. Reduced SSI rate and better outcomes can be achieved by controlling modifiable risk factors.

OBJECTIVE: The aim of the study was to determine the relationship between the Model for End-Stage Liver Disease (MELD) score and hepatic arterial hemodynamic parameters measured via Doppler US. PATIENTS AND METHODS: Etiologic causes and hepatic artery hemodynamic parameters of 121 patients with chronic liver parenchymal disease were compared with MELD scores. Doppler ultrasonography (US) was used to assess flow velocity, pulsatility index (PI) and resistance index (RI) in the hepatic artery (HA). Each patient's MELD scores were calculated at the time of Doppler ultrasound performed. RESULTS: There was statistically significant difference between MELD score and hepatic artery RI value (p < 0.001, r = 0.616). This difference was statistically more significant in the group which consisted of multiple etiologic causes (p < 0.001, r = 0.837). CONCLUSIONS: We found significant relation between MELD score and hepatic artery RI measurements in patients with chronic liver parenchymal disease.
