Abstract
BACKGROUND Many studies have suggested that volatile anesthetic use may improve postoperative outcomes after cardiac surgery compared to total intravenous anesthesia (TIVA) owing to its potential cardioprotective effect. However, the results were inconclusive, and few studies have included patients undergoing heart valve surgery. METHODS This nationwide population-based study included all adult patients who underwent heart valve surgery between 2010 and 2019 in Korea based on data from a health insurance claim database. Patients were divided based on the use of volatile anesthetics: the volatile anesthetics or TIVA groups. After stabilized inverse probability of treatment weighting (IPTW), the association between the use of volatile anesthetics and the risk of cumulative 1-year all-cause mortality (the primary outcome) and cumulative long-term (beyond 1 year) mortality were assessed using Cox regression analysis. RESULTS Of the 30,755 patients included in this study, the overall incidence of 1-year mortality was 8.5%. After stabilized IPTW, the risk of cumulative 1-year mortality did not differ in the volatile anesthetics group compared to the TIVA group (hazard ratio, 0.98; 95% confidence interval, 0.90-1.07; P = .602), nor did the risk of cumulative long-term mortality (hazard ratio, 0.98; 95% confidence interval, 0.93-1.04; P = .579) at a median (interquartile range) follow-up duration of 4.8 (2.6-7.6) years. CONCLUSIONS Compared with TIVA, volatile anesthetic use was not associated with reduced postoperative mortality risk in patients undergoing heart valve surgery. Our findings indicate that the use of volatile anesthetics does not have a significant impact on mortality after heart valve surgery. Therefore, the choice of anesthesia type can be based on the anesthesiologists' or institutional preference and experience.

Comparison of serum dynamic thiol/disulphide homeostasis and nitric oxide levels of total intravenous vs inhaled anaesthesia in endoscopic transsphenoidal pituitary surgery. Int J Clin Pract 2021; 75:e14485. [PMID: 34107152 DOI: 10.1111/ijcp.14485] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Accepted: 05/24/2021] [Indexed: 01/01/2023] Open
Abstract
BACKGROUND Transsphenoidal pituitary surgery (TPS) is traditionally performed under general anaesthesia. This study aimed to compare the effects of total intravenous anaesthesia (TIVA) or sevoflurane, an inhalation anaesthetic, on thiol-disulphide homeostasis in patients undergoing endoscopic endonasal TPS. METHODS In this study, 84 patients scheduled for TPS were randomly categorised into two groups: propofol (n = 42, the TIVA group) or sevoflurane (n = 42, the SEVO group). Blood samples were taken before induction of general anaesthesia and at the 30 minutes of postoperation. Serum native thiol and total thiol levels were detected, and the number of dynamic disulphide bonds and related ratios were calculated from these values. Serum nitric oxide (NO) levels were measured using a chemiluminescence method. RESULTS Although native thiol levels in TIVA postoperation group were markedly increased (P < .05), total thiol levels in SEVO postoperation group were significantly decreased (P < .01). Disulphide levels were declined in both groups (P < .05 for TIVA and P = .001 for SEVO groups). Disulphide/native thiol (P < .05 for both groups) and disulphide/total thiol ratios (P < .05 for TIVA and P < .01 for SEVO groups) were depressed in postoperation groups. We found a marked elevation in native thiol/total thiol ratio in both groups (P < .05 for TIVA and P < .01 for SEVO groups). There was significant augmentation in serum NO levels in the SEVO postoperation group (P < .05). CONCLUSION These results are the first to show that both TIVA and sevoflurane showed similar antioxidant effect with reduced disulphide levels, but sevoflurane may offer more robust oxidative stress protection and augmented NO production than TIVA during TPS. However, the clinical effect is needed to further investigate.

Abstract
Background: Myocardial protection in cardiac surgeries is a must and requires multimodal approaches in perioperative period to decrease and prevent the increase of myocardial oxygen demand and consumption that lead to postoperative cardiac complications including myocardial ischemia, dysfunction, and heart failure. Study Design: Prospective, controlled, randomized, double-blinded study. Aims: This study aims to study the effect of propofol-dexmedetomidine continuous infusion cardioprotection during open-heart surgery in adult patients. Materials and Methods: Sixty adult patients of both sexes aged from 30 to 60 years old belonging to the American Society of Anesthesiologists III or IV undergoing open-heart surgery were randomly divided into two equal groups: Group P (control group) received continuous infusion of propofol at a rate of 2 mg/kg/h and 50 cc 0.9% sodium chloride solution infused at a rate of 0.4 μg/kg/h (used as a placebo) and Group PD received continuous infusion of propofol at a rate of 2 mg/kg/h and dexmedetomidine 200 μg diluted in 50 cc 0.9% sodium chloride solution infused at a rate of 0.4 μg/kg/h. Infusion for all patients started immediately preoperative till skin closure. Hemodynamic measurements of heart rate (HR), invasive mean arterial pressure, and oxygen saturation were recorded at baseline before induction of anesthesia, immediately after intubation, at skin incision, at sternotomy and every 15 min in the 1st h then every 30 min during the prebypass period then every 15 min in the 1st h then every 30 min after weaning from CPB till the end of the surgery. Serum biomarkers; cardiac troponin (cTnI) and creatine kinase-myocardial bound (CK-MB) samples were measured basally (T1), 15 min after unclamping of the aorta (T2), immediate postoperative (T3), and 24 h postoperative (T4). Intraoperative data were also recorded including the number of coronary grafts, aortic cross-clamping duration, duration of cardiopulmonary bypass (CPB), duration of surgery, and rhythm of reperfusion. Fentanyl requirement, extubation time, and length of intensive care unit (ICU) stay were also recorded for every case. Results: There was no statistically significant differences as regard to demographic data between the studied two groups. HR and blood pressure recorded was lower in the PD group than the control group, and this difference was noted to be statistically significant. Furthermore, the PD group showed lower levels of myocardial enzymes (cTnI and CK-MB), decreased total fentanyl requirement, earlier postoperative extubation, and shorter ICU stay than the P (control) group. Conclusion: The use of propofol-dexmedetomidine in CPB surgeries offers more cardioprotective effects than the use of propofol alone.

The impact of total intravenous anesthesia versus inhalation anesthesia on acute kidney injury after major abdominal surgery: a propensity score analysis. J Anesth 2021; 35:112-121. [PMID: 33389161 DOI: 10.1007/s00540-020-02882-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Accepted: 11/13/2020] [Indexed: 12/29/2022]
Abstract
PURPOSE The effect of anesthetic types on postoperative acute kidney injury (AKI) remains unclear particularly in patients undergoing non-cardiac surgery. The purpose of this retrospective study was to compare total intravenous anesthesia (TIVA) and inhalation anesthesia in terms of the risk of AKI after open major abdominal surgery (MAS). METHODS Adult patients who underwent open MAS (gastrectomy, hepatectomy, colectomy, or pancreatectomy) at our institute from 2016 to 2018 were included. Using the multivariable logistic regression, the risk of postoperative AKI was compared among patients who underwent TIVA (TIVA group) and inhalation anesthesia (inhalation group) both in the total cohort and in the propensity score-matched cohort. Additional multivariable logistic regression analysis was performed with inverse probability of treatment weighting (IPTW) using the propensity score. RESULTS In total, 3616 patients were analyzed. The incidence of postoperative AKI was 5.0% (77/1546) and 7.8% (161/2070) in the TIVA and inhalation groups, respectively. The risk of AKI was significantly higher in the inhalation group [adjusted odds ratio (aOR) 1.72; 95% confidence interval (CI) 1.27-2.35; P = 0.002] than the TIVA group. In the matched cohort (n = 1518 in each group), the inhalation group also had a higher risk of AKI (aOR 1.66; 95% CI 1.20-2.31; P = 0.002). The multivariable logistic regression with IPTW showed similar results (aOR 1.59; 95% CI 1.30-1.95; P < 0.001). CONCLUSIONS The risk of AKI after open MAS differed significantly according to the anesthetic used. Patients receiving inhalation anesthesia may have a greater risk of postoperative AKI than those undergoing TIVA.

Abstract
Aim The objective of the present study was to compare the effect of sevoflurane with the sevoflurane-propofol combination on renal function in patients undergoing valvular heart surgery. The renal protective effect was assessed using a novel marker called neutrophil gelatinase-associated lipocalin (NGAL). Materials and Methods This was a prospective randomized controlled pilot study conducted at a tertiary care center in India. The study enrolled 36 patients undergoing elective valvular heart surgery, but only 31 were included. All the patients were randomized into two groups, that is, 15 in the sevoflurane group (S-group) and 16 in the sevoflurane-propofol group (SP-group). The baseline NGAL level and test NGAL level at 4 h after cardiopulmonary bypass were measured. Results There was a significant rise in the test NGAL levels compared to baseline in both the groups. The test NGAL level in the S-group was significantly high compared to that of the SP-group (P = 0.034). The number of patients with acute kidney injury was less in the SP-group without reaching statistical significance (P = 0.210). Conclusion Renal function was better preserved in patients anesthetized with a combination of sevoflurane and propofol. This could be due to the enhanced protective effect on renal function by both sevoflurane and propofol.

Abstract
Background Anesthesia and surgery may deteriorate liver function in patients with elevated liver enzyme levels; therefore, in these patients, choosing anesthetics with less hepatotoxicity is important. Methods This retrospective study investigated the effect of total intravenous anesthesia (TIVA) versus inhalation anesthesia (INHA) on the postoperative liver function in patients with preoperatively elevated liver enzyme levels (aspartate transaminase [AST] or alanine transaminase [ALT] >40 U/L) who underwent non-hepatic surgery under general anesthesia. We compared the changes in enzyme levels within 24 hrs before and after surgery. Results In 730 patients (TIVA: n=138; INHA: n=592), the baseline characteristics were comparable, except for higher comorbidity rates in the TIVA group. The median anesthesia and operation times were significantly longer in the TIVA group because approximately 50% of the TIVA group (vs 19.7% of the INHA group) underwent neurosurgery, which had a relatively longer operation time than other surgeries. Intraoperative hypotensive events and vasopressor use were more frequent in the TIVA group. After 1:4 propensity score matching (TIVA: n=94; INHA: n=376), the baseline characteristics and surgical variables were comparable, except for longer anesthesia time. Before matching, postoperative AST and ALT changes were significantly lower in the TIVA group than in the INHA group. After matching, only the ALT change was significantly lower after TIVA than after INHA [median (interquartile range), -16.7 (-32 to -4) % vs -12.0 (-28.6-6.5) %, P=0.025]. Conclusion TIVA may be safer for patients with preoperatively elevated liver transaminase levels.

Abstract
Oxidative stress exacerbates brain damage following ischemia-reperfusion and traumatic brain injury (TBI). Management of TBI and critically ill patients commonly involves use of propofol, a sedation medication that acts as a general anesthetic with inherent antioxidant properties. Here we review available evidence from animal model systems and clinical studies that propofol protects against ischemia-reperfusion injury. However, evidence of propofol toxicity in humans exists and manifests as a rare complication, "propofol infusion syndrome" (PRIS). Evidence in animal models suggests that brain injury induces expression of the p75 neurotrophin receptor (p75NTR), which is associated with proapoptotic signaling. p75NTR-mediated apoptosis of neurons is further exacerbated by propofol's superinduction of p75NTR and concomitant inhibition of neurotrophin processing. Propofol is toxic to neurons but not astrocytes, a type of glial cell. Evidence suggests that propofol protects astrocytes from oxidative stress and stimulates astroglial-mediated protection of neurons. One may speculate that in brain injury patients under sedation/anesthesia, propofol provides brain tissue protection or aids in recovery by enhancing astrocyte function. Nevertheless, our understanding of neurologic recovery versus long-term neurological sequelae leading to neurodegeneration is poor, and it is also conceivable that propofol plays a partial as yet unrecognized role in long-term impairment of the injured brain.

Effects of Volatile versus Total Intravenous Anesthesia on Occurrence of Myocardial Injury after Non-Cardiac Surgery. J Clin Med 2019; 8:jcm8111999.

Abstract
The cardioprotective effects of volatile anesthetics versus total intravenous anesthesia (TIVA) are controversial, especially in patients undergoing non-cardiac surgery. Using current generation high-sensitivity cardiac troponin (hs-cTn), we aimed to evaluate the effect of anesthetics on the occurrence of myocardial injury after non-cardiac surgery (MINS). From February 2010 to December 2016, 3555 patients without preoperative hs-cTn elevation underwent non-cardiac surgery under general anesthesia. Patients were grouped according to anesthetic agent; 659 patients were classified into a propofol-remifentanil total intravenous anesthesia (TIVA) group, and 2896 patients were classified into a volatile group. To balance the use of remifentanil between groups, a balanced group (n = 1622) was generated with patients who received remifentanil infusion in the volatile group, and two separate comparisons were performed (TIVA vs. volatile and TIVA vs. balanced). The primary outcome was occurrence of MINS, defined as rise of hs-cTn I ≥ 0.04 ng/mL within postoperative 48 hours. The secondary outcomes were 30-day mortality, postoperative acute kidney injury (AKI), and adverse events during hospital stay (mortality, type I myocardial infarction (MI), and new-onset arrhythmia). In propensity-matched analyses, the occurrence of MINS was lower in the TIVA group compared to the volatile group (OR 0.642; 95% CI 0.450–0.914; p = 0.014). However, after balancing the use of remifentanil, there was no difference between groups in the risk of MINS (OR 0.832; 95% CI 0.554–1.251; p-value = 0.377). There were no significant associations between the two groups in type 1 MI, new-onset atrial fibrillation, in-hospital and 30-day mortality before and after balancing the use of remifentanil. However, the incidence of postoperative AKI was lower in the TIVA group (OR 0.362; 95% CI 0.194–0.675; p-value = 0.001). After balancing the use of remifentanil, volatile anesthesia and TIVA showed comparable effects on MINS in patients undergoing non-cardiac surgery without preoperative myocardial injury. Further studies are needed on the benefit of remifentanil infusion.

Abstract
The care of patients with acute kidney injury (AKI) has been limited due to the lack of effective therapeutics that can either prevent AKI during high-risk situations or treat AKI once established. A revolution in the scientific understanding of the pathogenesis of AKI has led to the identification of potential therapeutic targets. These targets include pathways involved in inflammation, cellular repair and fibrosis, cellular metabolism and mitochondrial function, oxidative stress, apoptosis, and hemodynamics and oxygen delivery. Many compounds are entering early-phase clinical trials. In addition, efforts to better describe sub-categories of AKI (through endo-phenotyping) hold promise to target therapies more effectively based upon pathways that are operative in the pathogenesis. These advances bring optimism that the care of patients with AKI will be transformed with the hope of better outcomes.

Effects of propofol on the inflammatory response during robot-assisted laparoscopic radical prostatectomy: a prospective randomized controlled study. Sci Rep 2019; 9:5242. [PMID: 30918320 PMCID: PMC6437140 DOI: 10.1038/s41598-019-41708-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Accepted: 02/21/2019] [Indexed: 12/20/2022] Open
Abstract
Robot-assisted laparoscopic radical prostatectomy (RALRP) is a minimally invasive procedure; however, some amount of surgical trauma that can trigger systemic inflammation remains. Moreover, pneumoperitoneum during RALRP induces ischemia–reperfusion injury (IRI). Propofol, an anesthetic, is known to have anti-inflammatory and antioxidant properties. In the present study, we compared the effects of propofol with those of desflurane on inflammation and IRI during RALRP via measurements of different biomarkers and evaluation of perioperative renal function. Fifty patients were randomized to receive either desflurane (n = 25) or propofol (n = 25) with remifentanil during RALRP. Serum levels of interleukin (IL)-6 (IL-6), tumor necrosis factor alpha, C-reactive protein, and nitric oxide were measured 10 min after anesthesia induction (T1), 100 min after carbon dioxide (CO2) insufflation (T2), and 10 min after CO2 deflation (T3). Perioperative urine outputs and the serum creatinine level at 24 h after surgery were also recorded. We found that IL-6 levels at T2 and T3 were higher than those at T1 in both groups, although the increases were significant attenuated only in the propofol group. The other parameters showed no differences among the three time points in both groups. The intraoperative urine output was significantly higher in the propofol group than in the desflurane group, while the creatinine level showed no significant changes in either group. Our findings suggest that propofol can not only attenuate the inflammatory response during and after pneumoperitoneum in patients undergoing RALRP but also prevent oliguria during pneumoperitoneum.

Abstract
Acute kidney injury (AKI) is a common disease with a complex pathophysiology. The old paradigm of identifying renal injury based on location-prerenal, intrarenal, and postrenal-is now being supplanted with a new paradigm based on observable kidney injury patterns. The pathophysiology of AKI on a molecular and microanatomical level includes inflammation, immune dysregulation, oxidative injury, and impaired microcirculation. Treatment has traditionally been supportive, including the avoidance of nephrotoxins, judicious volume and blood pressure management, hemodynamic monitoring, and renal replacement therapy. Fluid overload and chloride-rich fluids are now implicated in the development of AKI, and resuscitation with a balanced, buffered solution at a conservative rate will mitigate risk. Novel therapies, which address specific observable kidney injury patterns include direct oxygen-free radical scavengers such as α-lipoic acid, curcumin, sodium-2-mercaptoethane sulphonate, propofol, and selenium. In addition, angiotensin II and adenosine receptor antagonists hope to ameliorate kidney injury via manipulation of renal hemodynamics and tubulo-glomerular feedback. Alkaline phosphatase, sphingosine 1 phosphate analogues, and dipeptidylpeptidase-4 inhibitors counteract kidney injury via manipulation of inflammatory pathways. Finally, genetic modifiers such as 5INP may mitigate AKI via transcriptive processes.

Abstract
BACKGROUND Renal injury is a common cause of morbidity and mortality after elective abdominal aortic aneurysm (AAA) repair. Propofol has been reported to protect several organs from ischemia/reperfusion (I/R) induced injury. We performed a randomized clinical trial to compare propofol and sevoflurane for their effects on renal I/R injury in patients undergoing elective AAA repair. MATERIALS AND METHODS Fifty patients scheduled for elective AAA repair were randomized to receive propofol anesthesia in group I or sevoflurane anesthesia in group II. Urinary specific kidney proteins (N-acetyl-beta-glucosamidase, alpha-1-microglobulin, glutathione transferase [GST]-pi, GST-alpha) were measured within 5 min of starting anesthesia as a base line (T0), at the end of surgery (T1), 8 h after surgery (T2), 16 h after surgery (T3), and 24 h postoperatively (T4). Serum pro-inflammatory cytokines (tumor necrosis factor-α and interleukin 1-β) were measured at the same time points. In addition, serum creatinine and cystatin C were measured before starting surgery as a baseline and at days 1, 3, and 6 after surgery. RESULTS Postoperative urinary concentrations of all measured kidney specific proteins and serum pro-inflammatory cytokines were significantly lower in the propofol group. In addition, the serum creatinine and cystatin C were significantly lower in the propofol group compared with the sevoflurane group. CONCLUSION Propofol significantly reduced renal injury after elective open AAA repair and this could have clinical implications in situations of expected renal I/R injury.

Abstract
Acute kidney injury (AKI) is a common complication in critically ill patients and subsequently worsens outcomes. Although many drugs to prevent and treat AKI have shown benefits in preclinical models, no specific agent has been shown to benefit AKI in humans. Moreover, despite remarkable advances in dialysis techniques that enable management of AKI in hemodynamically unstable patients with shock, dialysis-requiring severe AKI is still associated with an unacceptably high mortality rate. Thus, focusing only on kidney damage and loss of renal function has not been sufficient to improve outcomes of patients with AKI. Recent data from basic and clinical research have begun to elucidate complex organ interactions in AKI between kidney and distant organs, including heart, lung, spleen, brain, liver, and gut. This review serves to update the topic of organ cross talk in AKI and focuses on potential therapeutic targets to improve patient outcomes during AKI-associated multiple organ failure.

Abstract
BACKGROUND AND OBJECTIVES Propofol has been shown to provide protection against renal ischemia/reperfusion injury experimentally, but clinical evidence is limited to patients undergoing cardiac surgery. There are no data about its association with oliguria and AKI in critically ill patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We obtained data from the Multiparameter Intelligent Monitoring in Intensive Care II database (2001-2008). Patient selection criteria included adult patients in their first intensive care unit (ICU) admission, need for mechanical ventilation, and treatment with propofol or midazolam. Propensity score analysis (1:1) was used and renal-related outcomes (AKI, oliguria, cumulative fluid balance, and need for RRT) were evaluated during the first 7 days of ICU stay. RESULTS There were 1396 propofol/midazolam-matched patients. AKI in the first 7-day ICU time period was statistically lower in propofol-treated patients compared with midazolam-treated patients (55.0% versus 67.3%, P<0.001). Propofol was associated with lower AKI incidence using both urine output (45.0% versus 55.7%, P<0.001) and serum creatinine criteria (28.8% versus 37.2%, P=0.001). Patients receiving propofol had oliguria (<400 ml/d) less frequently (12.4% versus 19.6%, P=0.001) and had diuretics prescribed less often (8.5% versus 14.3%, P=0.001). In addition, during the first 7 days of ICU stay, patients receiving propofol less frequently achieved cumulative fluid balance >5% of body weight (50.1% versus 58.3%, P=0.01). The need for RRT in the first 7 days of ICU stay was also less frequent in propofol-treated patients (3.4% versus 5.9%, P=0.03). ICU mortality was lower in propofol-treated patients (14.6% versus 29.7%, P<0.001). CONCLUSIONS In this large, propensity-matched ICU population, patients treated with propofol had a lower risk of AKI, fluid-related complications, and need for RRT.

Propofol increases morbidity and mortality in a rat model of sepsis. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2015; 19:45.

Abstract
INTRODUCTION Severe sepsis is associated with approximately 50% mortality and accounts for tremendous healthcare costs. Most patients require ventilatory support and propofol is commonly used to sedate mechanically ventilated patients. Volatile anesthetics have been shown to attenuate inflammation in a variety of different settings. We therefore hypothesized that volatile anesthetic agents may offer beneficial immunomodulatory effects during the course of long-term intra-abdominal sepsis in rats under continuous sedation and ventilation for up to 24 hours. METHODS Sham operation or cecal ligation and puncture (CLP) was performed in adult male Wistar rats followed by mechanical ventilation. Animals were sedated for 24 hours with propofol (7 to 20 mg/kg/h), sevoflurane, desflurane or isoflurane (0.7 minimal alveolar concentration each). RESULTS Septic animals sedated with propofol showed a mean survival time of 12 hours, whereas >56% of all animals in the volatile groups survived 24 hours (P <0.001). After 18 hours, base excess in propofol + CLP animals (-20.6 ± 2.0) was lower than in the volatile groups (isoflurane + CLP: -11.7 ± 4.2, sevoflurane + CLP: -11.8 ± 3.5, desflurane + CLP -14.2 ± 3.7; all P <0.03). Plasma endotoxin levels reached 2-fold higher levels in propofol + CLP compared to isoflurane + CLP animals at 12 hours (P <0.001). Also blood levels of inflammatory mediators (tumor necrosis factor-α, interleukin-1β, interleukin-10, CXCL-2, interferon-γ and high mobility group protein-1) were accentuated in propofol + CLP rats compared to the isoflurane + CLP group at the same time point (P <0.04). CONCLUSIONS This is the first study to assess prolonged effects of sepsis and long-term application of volatile sedatives compared to propofol on survival, cardiovascular, inflammatory and end organ parameters. Results indicate that volatile anesthetics dramatically improved survival and attenuate systemic inflammation as compared to propofol. The main mechanism responsible for adverse propofol effects could be an enhanced plasma endotoxin concentration, leading to profound hypotension, which was unresponsive to fluid resuscitation.

Abstract
Our previous studies demonstrated that inflammatory reaction and neuronal apoptosis are the most important pathological mechanisms in ischemia-induced brain damage. Propofol has been shown to attenuate ischemic brain damage via inhibiting neuronal apoptosis. The present study was performed to evaluate the effect of propofol on brain damage and inflammatory reaction in rats of focal cerebral ischemia. Sprague-Dawley rats underwent permanent middle cerebral artery occlusion, then received treatment with propofol (10 or 50 mg/kg) or vehicle after 2 h of ischemia. Neurological deficit scores, cerebral infarct size and morphological characteristic were measured 24 h after cerebral ischemia. The enzymatic activity of myeloperoxidase (MPO) was assessed 24 h after cerebral ischemia. Nuclear factor-kappa B (NF-κB) p65 expression in ischemic rat brain was detected by western blot. Cyclooxygenase-2 (COX-2) expression in ischemic rat brain was determined by immunohistochemistry. ELISA was performed to detect the serum concentration of tumor necrosis factor-α (TNF-α). Neurological deficit scores, cerebral infarct size and MPO activity were significantly reduced by propofol administration. Furthermore, expression of NF-κB, COX-2 and TNF-α were attenuated by propofol administration. Our results demonstrated that propofol (10 and 50 mg/kg) reduces inflammatory reaction and brain damage in focal cerebral ischemia in rats. Propofol exerts neuroprotection against ischemic brain damage, which might be associated with the attenuation of inflammatory reaction and the inhibition of inflammatory genes.

Abstract
OBJECTIVES The aim of this study was to determine the relationship between the antioxidant profile of anesthetics and its relation to total antioxidant capacity (TAC) of plasma in children who underwent tourniquet-induced ischemia-reperfusion (IR) injury during extremity operations. METHODS Children were randomized into three groups: general inhalational anesthesia with sevoflurane (group S), total intravenous anesthesia (TIVA) with propofol (group T), and regional anesthesia (group R). Venous blood samples were obtained before peripheral nerve block and induction of general anesthesia (baseline), 1 minute before tourniquet release (BTR), and 5 and 20 minutes after tourniquet release (ATR). Plasma TAC as well as antioxidant potential of propofol, thiopental, and bupivacaine were measured using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. RESULTS Plasma TAC in group T was increased significantly at 20 minutes ATR in comparison with basal and BTR values, and also was significantly higher in comparison with plasma TAC in groups S and R measured at the same time point. The radical scavenging activity of anesthetics in vitro indicated that only propofol possessed a significant antioxidative activity in the reaction with DPPH radical in comparison with thiopental and bupivacaine. DISCUSSION These data confirm that TIVA with propofol attenuates oxidative stress related to tourniquet-induced ischaemia-reperfusion injury in children.

Differential influence of propofol on different cell types in terms of the expression of various oxidative stress-related enzymes in an experimental endotoxemia model.

Abstract
OBJECTIVES Both overproduction of nitric oxide and oxidative injury to the cardiovascular and pulmonary systems contribute to fatal pathophysiology during endotoxemia. We investigated the effect of propofol on oxidative stress-related enzymes in lung (L2), heart (H9C2) and macrophage (NR8383) cells during endotoxemia. METHODS Experimental endotoxemia was induced by co-culture of Escherichia coli lipopolysaccharide (15 μg/mL) in the abovementioned three types of cells that were under the effect of propofol (15 or 30 μM for 1 or 4 hours). Cellular expression of induced nitric oxide synthase (iNOS), superoxide dismutase (SOD) 1 and 2, and p47phox (representing NADPH oxidase) were determined by immunoblotting. The cellular oxidative burst activity was determined using a dihydroethidium method via flow cytometry to represent the level of reactive oxygen species. The in vivo endotoxemia model was also employed for comparison using a systemic injection of lipopolysaccharide (15 mg/kg) under propofol maintenance (15 or 30 mg/kg/h). The Student t test (two groups) was used for statistical evaluation among the means, and the Newman-Keuls test was used for analysis of variance in the statistical analysis. RESULTS In lung L2 cells, propofol significantly reduced the expression of iNOS, SOD1, SOD2, and p47phox under LPS-induced endotoxemia. However, in H9C2 cardiac cells and NR8383 macrophages, only the expression of iNOS was significantly suppressed, but not that of SOD1, SOD2, or p47phox. The level of reactive oxygen species was suppressed in all three kinds of cell. In in vivo animal tissue, except for the suppression of iNOS expression in lung and heart cells, propofol in lung cells produced only SOD1 suppression, but in rat heart the expression of both SOD1 and SOD2 was suppressed. CONCLUSION These results suggest that propofol may have a protective role for lung cells. This effect is associated with its suppression of oxidative-related enzymes, including iNOS, SOD1, SOD2, and p47phox. In cardiac myocytes and macrophages, propofol also provides an antioxidative effect, probably via its inhibition of iNOS. The overall effect of propofol in the organs may be a combination of its effects on various cells. In addition, a reduction in reactive oxygen species plays a major role in the beneficial effect of propofol on experimental endotoxemia.

Abstract
Perioperative increase in oxidative activity in surgical patients reportedly prevents postoperative surgical site infection (SSI). Several clinical studies have shown that oxidative activity under sevoflurane anaesthesia was higher than that under propofol anaesthesia. Therefore, we hypothesised that sevoflurane anaesthesia would discourage SSI compared with propofol anaesthesia. To examine the effect of anaesthesia maintained with sevoflurane and propofol on SSI, a total of 265 consecutive adult patients, with American Society of Anesthesiologists physical status 1-3, who underwent elective open gastrointestinal surgery under general anaesthesia, were surveyed for SSI between January 2007 and December 2008. Sevoflurane or propofol was selected to maintain anaesthesia in 95 and 170 patients, respectively. A propensity score was used for pairwise matching of these patients to avoid selection biases between the two methods of anaesthesia. Propensity matching yielded 84 pairs of patients. We compared standardised infection ratios (SIRs), i.e. the quotient of the number of SSI cases observed and the number of SSI cases expected, calculated using data from the National Nosocomial Infection Surveillance, between sevoflurane and propofol anaesthesia. After propensity matching, SIR after sevoflurane anaesthesia was 1.89 [95% confidence interval (CI): 1.46-2.32], which was significantly lower than after propofol anaesthesia (4.78; 95% CI: 4.30-5.27) (P=0.02). This study suggests that sevoflurane tends to suppress SSI after elective open gastrointestinal surgery compared with propofol.

Abstract
BACKGROUND Propofol (2,6-diisopropylphenol) has been shown to protect several organs, including the kidneys, from ischemia-reperfusion (I-R)-induced injury. Although propofol affects adenosine triphosphate-sensitive potassium (K(ATP)) channels in nonrenal tissues, it is still not clear by which mechanisms propofol protects renal cells from such damage. In this study, we investigated whether propofol induces renal preconditioning through renal K(ATP) channels. METHODS A reversible ATP depletion (antimycin A) followed by restoration of substrate supply in LLC-PK1 cells was used as an in vitro model of renal I-R. Cell viability was assessed by dimethylthiazol-diphenyltetrazol bromide and trypan blue dye exclusion test assays. Apoptosis was evaluated by annexin V-fluorescein isothiocyanate staining by flow cytometry and immunofluorescence. Propofol treatments were initiated at various time intervals: 1 or 24 h before ischemia, only during ischemia, or only during reperfusion. To evaluate the mechanisms of propofol protection, specific K(ATP) channel inhibitors or activators were used in some experiments during propofol pretreatment. RESULTS Propofol attenuated I-R injury on LLC-PK1 cells when present either 1 or 24 h before initiated I-R, and also during the recovery period, but not when added only during ischemia. Propofol pretreatment significantly protected LLC-PK1 from I-R-induced apoptosis. The protective effect of propofol was prevented by glibenclamide (a sarcolemmal ATP-dependent K(+) channel blocker) and decreased by 5-hydroxidecanoic acid (a mitochondrial ATP-dependent K(+) channel blocker), but it was not modified by diazoxide (a selective opener of ATP-sensitive K(+) channel). CONCLUSION Propofol protected cells against apoptosis induced by I-R. This protection was probably due to a preconditioning effect of propofol and was, at least in part, mediated by K(ATP) channels.

Abstract
BACKGROUND Renal injury induced by aortic ischemia-reperfusion (IR) is an important factor in the development of postoperative acute renal failure following abdominal aortic surgery. Endothelin (ET) is involved in the development of renal injury induced by aortic IR and tezosentan (R0 61-0612) is a specific ET receptor antagonist. The aim of this study was to examine the effect of tezosentan on renal injury induced by abdominal aortic IR in rats. MATERIAL AND METHODS Twenty-four Wistar-Albino rats were randomized into three groups (eight per group). Control group underwent laparotomy and dissection of the infrarenal abdominal aorta (IAA) without occlusion. The aortic IR group underwent laparotomy and clamping of the IAA for 120 min followed by 120 min of reperfusion. Aortic IR + tezosentan group underwent same aortic IR periods, and received a bolus intravenous injection of 10 mg/kg tezosentan before ischemia plus continuous intravenous infusion of 1 mg/kg/h tezosentan during 120 min ischemia and 120 min reperfusion. At the end of the experiment, blood and kidney tissue specimens were obtained for biochemical analysis. Histological evaluation of the rat kidney tissues was also done. RESULTS Biochemical analysis showed that aortic IR significantly increased (P < 0.05 versus control) while tezosentan significantly decreased (P < 0.05 versus aortic IR) the tissue levels of malondialdehyde, superoxide dismutase, catalase and myeloperoxidase. Histological analyses showed that aortic IR significantly increased (P < 0.05 versus control) while tezosentan significantly decreased (P < 0.05 versus aortic IR) focal glomerular necrosis, dilatation of Bowman's capsule, degeneration of tubular epithelium, necrosis in tubular epithelium and tubular dilatation in the renal tissue samples. CONCLUSION The results of this study indicate that tezosentan reduces renal injury induced by aortic IR in rats. We think that tezosentan exerted this beneficial effect via reducing oxidative stress and lipid peroxidation, inhibition of leukocyte infiltration into renal tissue and acting cytoprotective on renal tubular cells after aortic IR.

Abstract
BACKGROUND Propofol has been reported to provide protection against ischemia-reperfusion injury. Nuclear transcription factor kappa B (NFkappaB) plays a key role in oxidative stress and the inflammatory response during ischemia-reperfusion. We compared the effect of propofol with sevoflurane on kidney NFkappaB expression and systemic inflammatory responses induced by aortic clamping. METHODS Twenty piglets were divided into four groups: sham surgery group with propofol (group SP, n = 5); sham group with sevoflurane (group SS, n = 5); and suprarenal clamping for 30 min with aorta-aortic bypass under propofol (group CP, n = 5) or sevoflurane (group CS, n = 5) anesthesia. Propofol was administered at 4 mg x kg(-1) x h(-1) i.v. and sevoflurane given at 1.5% inspiratory concentration. Peripheral blood and kidney biopsies were taken before the start of surgery, 15 min after unclamping the aorta, 24, 48, 72 h, and 7 days after surgery. Plasma creatinine, myeloperoxidase, tumor necrosis factor-alpha, interleukin 1-beta; and kidney superoxide anion and superoxidase dismutase were measured. The expression of inducible nitric oxide synthase and renal tissue NFkappaB was measured using Western blotting. RESULTS Compared with the CS group, animals in the CP group had lower concentrations of myeloperoxidase, tumor necrosis factor-alpha, interleukin 1beta, superoxide anion, superoxidase dismutase (P < 0.05) from 24 to 72 h after surgery and diminished NFkappaB expression and inducible nitric oxide synthase activity (P < 0.05) at 48 and 72 h after surgery, respectively. CONCLUSIONS Compared with sevoflurane, propofol administration during suprarenal aortic clamping and unclamping led to modulation of markers of inflammation and decreased NFkappaB expression.

Abstract
BACKGROUND Volatile anesthetics and hypothermia attenuate the inflammatory response. We aimed to compare the anti-inflammatory effects of sevoflurane and mild hypothermia during experimental endotoxemia in the rat. METHODS Anesthetized, ventilated Sprague-Dawley (SD) rats were randomly treated as follows (n = 6 per group): lipopolysaccharide (LPS) only, animals received LPS [LPS 5 mg/kg, intravenously (i.v.)] with no further treatment. In the LPS-hypothermia group, rats were cooled down to a temperature of 33 degrees C 15 min after LPS-injection (LPS 5 mg/kg i.v.). In animals of the LPS-sevoflurane group, sevoflurane inhalation (1 MAC) was initiated 15 min after induction of endotoxemia. The LPS-sevoflurane-hypothermia group received combined sevoflurane and hypothermia 15 min after induction of endotoxemia. A Sham group served as control without endotoxemia or treatment. After 4 h of endotoxemia, plasma levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-1beta (IL-1beta) and IL-10 were measured. Alveolar macrophages (AM) were ex vivo cultured for nitrite assay. RESULTS Inhalation of sevoflurane significantly attenuated plasma levels of TNF-alpha (-60%, P < 0.05) and IL-1beta (-68%, P < 0.05) as compared with the LPS-only group. Hypothermia and its combination with sevoflurane significantly reduced TNF-alpha levels (-46% and -58%, each P < 0.05), but not IL-1beta. Application of mild hypothermia and also its combination with sevoflurane resulted in a significant increase in plasma IL-10 as compared with endotoxemic controls. Nitrite release from AM was found to be significantly suppressed by sevoflurane (-83%), hypothermia (-73%) and by the combination of both (-67%) (P < 0.05, each). CONCLUSION Our data suggest that sevoflurane and mild hypothermia attenuate the inflammatory response during endotoxemia in vivo thus contributing to their beneficial role in clinical organ protection.

Abstract
Ischaemic/hypoxic insults to the brain during surgery and anaesthesia can result in long-term disability or death. Advances in resuscitation science encourage progress in clinical management of these problems. However, current practice remains largely founded on extrapolation from animal studies and limited clinical investigation. A major step was made with demonstration that rapid induction of mild sustained hypothermia in comatose survivors of out-of-hospital ventricular fibrillation cardiac arrest reduces death and neurological morbidity with negligible adverse events. This provides the first irrefutable evidence that outcome can be favourably altered in humans with widely applicable neuroprotection protocols. How far hypothermic protection can be extended to global ischaemia of other aetiologies remains to be determined. All available evidence suggests an adverse response to hyperthermia in ischaemic or post-ischaemic brain. Management of other physiological values can have dramatic effects in experimental injury models and this is largely supported by available clinical data. Hyperoxaemia may be beneficial in transient focal ischaemia but deleterious in global ischaemia. Hyperglycaemia causes exacerbation of most forms of cerebral ischaemia and this can be abated by restoration of normoglycaemia. Studies indicate little, if any, role for hyperventilation. There is little evidence in humans that pharmacological intervention is advantageous. Anaesthetics consistently and meaningfully improve outcome from experimental cerebral ischaemia, but only if present during the ischaemic insult. Emerging experimental data portend clinical breakthroughs in neuroprotection. In the interim, organized large-scale clinical trials could serve to better define limitations and efficacy of already available methods of intervention, aimed primarily at regulation of physiological homeostasis.
