Intra-abdominal pressure (IAP) is a critical physiological parameter that influences multiple organ systems, particularly in patients who have sustained trauma or undergone surgery. This study investigates the impact of sudden increases in intra-abdominal pressure on hemodynamics and myocardial function in military patients, particularly those experiencing abdominal trauma or undergoing abdominal surgery in combat settings. Elevated IAP, often resulting from trauma, fluid accumulation, or surgical procedures, can significantly affect cardiovascular stability, leading to alterations in cardiac output, blood pressure, and myocardial contractility. Through a retrospective review of military patients treated for abdominal injuries or surgeries, this study assesses the physiological changes in hemodynamics and myocardial function associated with acute IAP elevations. Key variables such as heart rate, blood pressure, central venous pressure, and echocardiographic measures of myocardial performance were monitored. The findings reveal that sudden increases in IAP result in significant hemodynamic instability, including reduced cardiac output and increased central venous pressure, as well as impaired myocardial contractile function. These changes are more pronounced in patients with severe abdominal trauma or those undergoing complex surgeries. The study underscores the importance of early detection and management of elevated IAP in military healthcare settings, where rapid intervention can prevent complications such as multi-organ dysfunction, ischemia, and even death. The results highlight the need for targeted strategies to monitor and mitigate the effects of IAP elevations on cardiovascular and myocardial function in military patients.
