Open Abdominal Aortic Aneurysm (AAA) repair is a high-risk surgical procedure accompanied by intense endocrine and metabolic responses to surgical stress, with subsequent activation of the inflammatory cascade, cytokine and acute-phase protein release, and bone marrow activation. There is a proven correlation of surgical stress, which patients undergoing open AAA repair are subjected to, with patient outcome, morbidity/mortality, intensive care unit stay and overall length of stay. Modern general anesthetic techniques have been revised and rely on perioperative multimodal anesthetic and analgesic strategies for improved overall patient outcome. Based on this context of a multimodal anesthetic technique and having taken into consideration the international "opioid-crisis" epidemic, an Opioid Free Anesthesia-Analgesia (OFA-A) strategy started to emerge. It is based on the administration of a variety of anesthetic/analgesic agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects.
Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, involving the administration of pregabalin, ketamine, dexmedetomidine, lidocaine, dexamethasone, dexketoprofen, paracetamol and magnesium sulphate, will lead to attenuation of surgical stress response compared to a conventional Opioid-Based Anesthesia-Analgesia (OBA-A) strategy. Furthermore, the anticipated attenuation of the inflammatory response, is pressumed to be associated with equal or improved analgesia, compared to a perioperative OBA-A technique.
Open abdominal aortic aneurysm (AAA) repair surgery is a high-risk operation, often performed on high-risk patients. Despite advancements made in diagnosis, management, surgical techniques and treatment of these patients, morbidity and mortality remain high. Mortality after open AAA repair remains higher than the average mortality of the matched population for age and sex. Debate is ongoing as to whether open AAA repair or endovascular aneurysm repair (EVAR) is better in terms of overall long-term survival rate.
Regarding open AAA repair, the very nature of the surgery itself, with surgical trauma, aortic cross clamping and its resulting ischemia-reperfusion injury, and cellular interactions of blood with the biomaterial surface of the graft, causes intense and varied metabolic, endocrine and immunological responses. These surgical stress-related responses are evident as marked increases in inflammatory cytokines such as TNF-a, IL-1a, IL-6, IL-8, IL-10, stimulation of the sympathetic system, and stimulation of the hypothalamic-pituitary-adrenal axis, caused by release of CRH and AVP. High levels of IL-6, peaking at 4-48h after clamp removal, have been associated with serious postoperative complications and its levels reflect the intensity of surgical trauma following AAA repair. Other inflammation markers such as CRP and leukocytes have also been shown to increase postoperatively.
While the surgical technique has been extensively studied as to the role it plays on the control of the surgical stress response, patient outcome, morbidity and overall mortality, fewer studies have been conducted to study the effect of the anesthetic management on these factors. While most of them have been focusing on the comparison of general anesthetic vs regional techniques, only few compare different general anesthetic techniques on patient outcome.
Modern general anesthetic techniques have been revised and rely on a multimodal anesthetic and analgesic perioperative regimen for improved patient outcome. A multimodal regimen requires the administration of at least 2 factors with different mechanisms of action. At least one factor causes inhibition of central sensitization and at least another one inhibits the peripheral sensitization of the nervous system, as a response to painful surgical stimuli, mitigating adverse neuroplasticity. One such example, is an Opioid-Free Anesthetic-Analgesic (OFA-A) strategy, which implements a variety of pharmacological agents, including some with demonstrated immunomodulating and anti-inflammatory effects. Apart from sparing any opioid-related adverse effects, an OFA-A multimodal strategy targets optimal analgesia with a multitude of factors in the lowest possible dose, aiming for additive or synergistic effects. An additional advantage of using an OFA-A technique is the prevention of opioid-induced hyperalgesia.
Our hypothesis is that implementation of a multimodal OFA-A strategy, leads to a decreased sympathetic and inflammatory response, compared to conventional opioid-based anesthetic techniques. A decreased inflammatory and stress response as expressed by reduced levels of IL-6, IL-8, IL-10, TNF-a, CRP, cortisol, arginine vasopressin (AVP), white blood cells count and hemodynamic stability is expected to decrease peripheral and central sensitization, contributing to better postoperative analgesia.

Patients will be given a standardized CAPA questionaire that has pre-determined answers that patients will be able to choose from, to best describe their pain. In regards to sleep, if the pain is waking patients up, available answers will be: 1. Awake with pain most of the night 2. Awake with occasional pain 3. Normal sleep The percentage of patients whose sleep is reported as "Normal sleep" will be reported
Time frame: 2) Second postoperative day
