Brief Summary:
The goal of this observational study is to examine whether intrahepatic blood flow occlusion strategies during partial hepatectomy are associated with postoperative cardiac injury in patients undergoing hepatectomy. The primary questions it seeks to address are:
1. Are the intrahepatic blood flow occlusion method, the number of occlusions, and the cumulative occlusion time associated with postoperative cardiac injury?
2. How do intrahepatic blood flow occlusion, intraoperative hypotension, and postoperative cardiac injury interact? Participants will contribute their inpatient medical records, including information on medical history, surgical procedures, and anesthesia details.
Detailed Description:
Liver resection is currently the primary surgical treatment for liver tumors, injuries, and other diseases. With the continuous development of surgical techniques, its application has been expanding. However, intraoperative bleeding and poor surgical field exposure remain major challenges in liver resection, seriously affecting the safety and efficacy of the operation.
Hepatic inflow occlusion is a commonly used technique to address these challenges. It can effectively reduce intraoperative bleeding and improve surgical field exposure. However, it can also lead to hepatic ischemia-reperfusion injury, which may aggravate the damage to the remnant liver and even affect liver regeneration.
Recent studies suggest that hepatic ischemia-reperfusion injury may affect distant organs such as the kidneys, brain, lungs, and heart. However, there is still insufficient clinical evidence, especially regarding myocardial injury. In addition, intraoperative hypotension is a common complication of liver resection and may exacerbate the impact of ischemia-reperfusion injury on the myocardium.
This study intends to construct a model incorporating variables related to intraoperative hepatic ischemia and reperfusion, and analyze the relationship between hepatic inflow occlusion and postoperative myocardial injury in liver resection using logistic regression, while considering the mediating effect of hypotension. The results of this study will provide important clinical evidence for optimizing liver resection strategies, reducing myocardial injury, and improving patient prognosis. This research holds significant scientific and clinical value, and is expected to improve the quality of liver surgery and patient survival rates.
