Background and Objectives: The management of acute postoperative pain (APP) following major abdominal surgery implies various analgetic strategies. Opioids lie at the core of every analgesia protocol, despite their side effect profile. To limit patients’ exposure to opioids, considerable effort has been made to define new opioid-sparing anesthesia techniques relying on multimodal analgesia. Our study aims to investigate the role of adjuvant multimodal analgesic agents, such as ketamine, lidocaine, and epidural analgesia in perioperative pain control, the incidence of postoperative cognitive dysfunction (POCD), and the incidence of postoperative nausea and vomiting (PONV) after major abdominal surgery. Materials and Methods: This is a clinical, observational, randomized, monocentric study, in which 80 patients were enrolled and divided into three groups: Standard group, C (n = 32), where patients received perioperative opioids combined with a fixed regimen of metamizole/acetaminophen for pain control; co-analgetic group, Co-A (n = 26), where, in addition to standard therapy, patients received perioperative systemic ketamine and lidocaine; and the epidural group, EA (n = 22), which included patients that received standard perioperative analgetic therapy combined with epidural analgesia. We considered the primary outcome, the postoperative pain intensity, assessed by the visual analogue scale (VAS) at 1 h, 6 h, and 12 h postoperatively. The secondary outcomes were the total intraoperative fentanyl dose, total postoperative morphine dose, maximal intraoperative sevoflurane concentration, confusion assessment method for intensive care units score (CAM-ICU) at 1 h, 6 h, and 12 h postoperatively, and the postoperative dose of ondansetron as a marker for postoperative nausea and vomiting (PONV) severity. Results: We observed a significant decrease in VAS score, as the primary outcome, for both multimodal analgesic regimens, as compared to the control. Moreover, the intraoperative fentanyl and postoperative morphine doses were, consequently, reduced. The maximal sevoflurane concentration and POCD were reduced by EA. No differences were observed between groups concerning PONV severity. Conclusions: Multimodal analgesia concepts should be individualized based on the patient’s needs and consent. Efforts should be made to develop strategies that can aid in the reduction of opioid use in a perioperative setting and improve the standard of care.

Introduction Takotsubo cardiomyopathy is a rare reversible type of heart failure, often precipitated by emotional stress; other risk factors include intracranial bleeding, ischemic stroke, sepsis, major surgery, pheochromocytoma. The clinical, electrical and blood sample analysis features resemble those of a myocardial infarction- however, they occur in the absence of angiographic coronary filling defects. Case presentation A 61-year-old male patient, 71 kg, 175 cm, underwent liver transplantation for Child-Pugh B cirrhosis secondary to mixed viral hepatitis (B and D). His medical records revealed mild mitral, aortic, and tricuspid insufficiencies and heart failure with preserved ejection fraction. An initially uneventful perioperative stage was succeeded by cardiogenic shock (cardiac index – 1.2 l/min/ sqm), which the patient developed 24 hours after the intervention. Elevated cardiac markers and ECG abnormalities showing ST-T changes in the V2-V5 leads were additionally noted. Transesophageal echocardiography (TEE) revealed an acute onset reduction in the left ventricular systolic function secondary to basal hypokinesia. No coronary obstruction was detected by percutaneous angiography. The above findings lead to the diagnosis of reverseTakotsubo cardiomyopathy. Further, the patient developed acute kidney injury and liver graft failure, succumbing within 48 hours after the surgical procedure. Conclusions We report a rare case of reverse Takotsubo cardiomyopathy in a male patient after orthotopic liver transplant.
