BACKGROUND: Patients undergoing surgery often feel anxious. Accumulating evidence indicated that presurgical anxiety was related to the more severe postsurgical pain. An animal model was established that exposed Sprague-Dawley rats to a single-prolonged stress (SPS) procedure to induce presurgical anxiety-like behaviors. The experiment revealed that presurgical anxiety not only aggravated but also prolonged postsurgical pain. However, the underlying mechanisms were unknown. METHODS: The rats in group C + Cort, group I + Cort, group A + Cort, and group AI + Cort were injected with corticosterone...

The current case report represents a warning against serious hyperkalaemia and acidosis induced by ACE-I during surgical stress while normal renal function could deceive the attending anaesthetist. Arterial gas analysis for follow-up of haemoglobin loss accidentally discovered hyperkalaemia and acidosis. Glucose-insulin and furosemide successfully corrected hyperkalaemia after 25 minutes and acidosis after 3 hours. These complications could be explained by a deficient steroid stress response to surgery secondary to suppression by ACE-I...

Objective The transversus abdominis plane (TAP) block ameliorates visual analogue scale scores and decreases morphine requirements, but its role remains unclear. Patients of advanced age are susceptible to local anesthetic intoxication. We aimed to identify an optimal concentration that can be used in enhanced recovery after surgery (ERAS) without compromising analgesic efficacy. Methods In total, 120 patients aged ≥65 years undergoing laparoscopic rectal cancer surgery received general anesthesia combined with a TAP block using 0...

Acute kidney injury (AKI) and metabolic dysfunction are critical complications in sepsis syndrome; however, their pathophysiological mechanisms remain poorly understood. Therefore, we evaluated whether the pharmacological properties of 6-gingerol (6G) and 10-gingerol (10G) could modulate AKI and metabolic disruption in a rat model of sepsis (faecal peritonitis). Animals from the sham and AKI groups were intraperitoneally injected with 6G or 10G (25 mg/kg). Septic AKI decreased creatinine clearance and renal antioxidant activity, but enhanced oxidative stress and the renal mRNA levels of tumour necrosis factor-α, interleukin-1β, and transforming growth factor-β...

BACKGROUND: Antegrade cerebral perfusion (ACP) is the standard neuroprotection method in aortic surgery. Visceral ischemia during this modality brings out some controversies. We aimed to investigate the level of oxidative stress at the lower part of body during ACP. METHODS: Thirty consecutive patients underwent elective ascending aorta and hemiarch repair with ACP (without distal perfusion) were enrolled to study. The patients were enrolled into two groups which were based on 50th percentile of ACP duration (15 patients in each group)...

During physiological stress (e.g. exercise, hypoxia) blood flow is shunted to specific anatomical regions to protect critical organs, yet, splenic blood flow in these circumstances remains to be investigated. Despite being classically viewed as a non-critical organ, recent experimental and epidemiological evidence suggests the spleen plays a significant role in cardiovascular pathophysiology. We hypothesized that splenic blood flow is prioritized in the development of heart failure (i.e. chronic state of reduced cardiac output)...

Acute kidney injury (AKI) is a major public health concern, which is contributing to serious hospital complications, chronic kidney disease (CKD) and even death. Renal ischemia-reperfusion injury (IRI) remains a leading cause of AKI. The stress-responsive enzyme, heme oxygenase-1 (HO-1) mediates protection against renal IRI and may be preventively induced using hemin prior to renal insult. This HO-1 induction pathway called hemin preconditioning is largely known to be effective. Therefore, HO-1 might be an interesting therapeutic target in case of predictable AKI (e...

BACKGROUND:  Neonates undergoing cardiopulmonary bypass (CPB) surgery to correct congenital heart defects often experience excessive bleeding. Exposure of blood to artificial materials during CPB may activate coagulation, complement and inflammatory pathways. In addition, the surgical stress placed on the haemostatic system may result in cross-activation of other plasma proteolytic cascades, which could further complicate physiological responses to the surgical procedure and post-operative recovery...

BACKGROUND: Neurogenic thoracic outlet syndrome (NTOS) is the most common form of TOS and may occur from injury, occupational stress or athletic endeavors. While most patients with NTOS will improve after first rib resection and scalenectomy (FRRS), the prognostic risk factors for success remain unclear. Athletes are a very motivated and disciplined demographic and therefore should be a group more likely to respond to FRRS for NTOS than non-athletes. We hypothesized that athletes would do better after FRRS than non-athletes despite the added physical stress that sporting activity imposes...

Continued advancements in perioperative care and anesthesia technology have improved surgical outcomes and accelerated the patient's ability to resume preoperative activities. With the current emphasis on decreased utilization of expensive hospital resources, a shorter length of stay while maintaining patient satisfaction is encouraged for maximum reimbursement. Through the implementation of evidence-based protocols that standardize care and promote patient medical optimization, the surgical stress response, complications, and time spent in the hospital can be reduced...

Ischemia-reperfusion injury (IRI) is a major cause of lung dysfunction during cardiovascular surgery, heart transplantation and cardiopulmonary bypass procedures, and the inflammatory response, oxidative stress, and apoptosis play key and allegedly maladaptive roles in its pathogenesis. The aim of this study was to initially elucidate whether ozone induces oxidative preconditioning by activating nuclear factor (erythroid-derived 2)-like 2 (Nrf2) and secondly to determine whether ozone oxidative preconditioning (OzoneOP) protects the lung from IRI by attenuating nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3 (NLRP3)-mediated inflammation, enhancing the antioxidant activity of Nrf2 and inhibiting apoptosis...

Silicone breast implant is associated with complications inherent to the surgical procedure. Prosthesis coating with polyurethane, however, commonly reduces the incidence of such complications. In this paper, the authors evaluated the inflammatory histomorphometric profile and oxidative damage associated to the implant of polyester urethane sheets. Forty-eight Wistar rats were divided into Sham or polyester urethane groups (n = 8/group) and underwent a polyester urethane implant in the dorsal skinfold. Tissue samples were collected on days seven, 30, and 90 after surgery and subjected to histomorphometric analysis and biochemical tests...

BACKGROUND Pain and surgical stress cause a pro-inflammatory response followed by downregulation of the immune response, which can increase the incidence of postoperative complications, such as infections or prolonged wound healing. T lymphocytes and natural killer (NK) cells have cytotoxic potential and are crucial components of cellular immunity, which is important for maintenance of immune balance. The aim of this study was to analyze the effects of 3 types of postoperative analgesia on the preservation and cytotoxic potential of T lymphocytes, NK cells, and their subpopulations, as well as NKT cells, in patients after total knee replacement (TKR) to find the most effective analgesic technique for mitigating immune suppression...

In the hypertrophic heart the myostructural afterload in the form of endoepicardial networks is predominant, which enhances myocardial hypertrophy. The intrinsic antagonism is derailed. Likewise, the connective tissue scaffold, i.e. the stromatogenic afterload, is enriched in the response to the derailment of antagonism in a hypertrophic heart up to regional captivation of the heart musculature. Due to the selective susceptibility of the auxotonic, contracting oblique transmural myocardial network for low dose negative inotropic medication, this promises to attenuate progress in myocardial hypertrophy...
