RESUMO
<b>Introduction:</b> Acute abdomen is one of the most common surgical emergencies faced by a surgeon. Monitoring Intra-Abdominal Pressure (IAP) in patients with acute abdomen referred for exploratory laparotomy may help guide the need for early intervention. </br></br> <b>Aim:</b> This study was performed to determine whether preoperative IAP had any significant association with organ failure as assessed using SOFA score. Furthermore, effect of IAP on patient outcome in terms of hospital stay, mortality was also evaluated. </br></br> <b>Materials and methods:</b> 60 patients above 18 years of age presenting with acute abdomen requiring exploratory laparotomy were included in this prospective observational study from November 2013 until March 2015. IAP and SOFA scores were calculated at the time of admission. The outcome of patients was assessed in terms of hospital stay, morbidity and mortality. The correlation between IAP and SOFA scores was also assessed to determine the risk of organ failure. The inferences were drawn with the use of SPSS v22.0 statistical software. ANOVA, Chi-square and Student's t-test were used in the analysis. </br></br> <b> Results:</b> There was a positive correlation between SOFA score and IAP; and this correlation was found to be statistically significant with Pearson's correlation coefficient being 0.6247 and significance levels being <0.0001. Both hospital stay and mortality positively correlated with the degree of IAP. </br></br> <b> Conclusions:</b> IAP should be routinely measured in patients with acute abdomen requiring exploratory laparotomy. Patients with preoperatively raised IAP should be referred for emergency surgery as soon as possible for better outcome.
