Ruptured abdominal aortic aneurysms (AAA) remain deadly. Survival is improved by initial fluid resuscitation response and maintaining blood pressure and temperature during surgery.
Area of Science:
Vascular Surgery
Surgical Outcomes
Critical Care Medicine
Background:
Ruptured abdominal aortic aneurysms (AAA) present a significant surgical challenge with high mortality rates.
Advances in anesthetic and postoperative care have not substantially reduced AAA-related deaths.
Purpose of the Study:
To identify factors influencing survival in patients undergoing surgery for ruptured AAA.
To analyze differences between survivors and non-survivors of ruptured AAA repair.
Main Methods:
Retrospective review of 33 patients undergoing ruptured AAA surgery between 1980-1986.
Comparison of demographic, clinical, and intraoperative variables between survivors and non-survivors.
Main Results:
Overall survival rate was 36.4% (12 survivors).
No significant differences were found in age, MAST trousers use, initial hemoglobin, initial blood pressure, operative time, or estimated blood loss.
Significant differences were observed in blood pressure during induction, intraoperatively, at the end of surgery, and final patient temperature.
Conclusions:
Patient response to initial fluid resuscitation before induction is critical for survival.
Maintaining stable blood pressure and body temperature throughout the operation significantly improves outcomes in ruptured AAA patients.
