Background: To prospectively investigate the predictive value of the preoperative C-reactive protein (CRP) concentration for major postoperative complications following off-pump coronary artery bypass (OPCAB) surgery. Methods and Results: From January 2007 to December 2007, 185 consecutive patients scheduled for elective OPCAB surgery were allocated to a low-CRP group (n=137, CRP <0.3 mg/dl) and a high-CRP group (n=48, CRP ≥0.3 mg/dl). The incidence of major postoperative complications, defined as postoperative myocardial infarction, and 5 major morbidity endpoints including permanent stroke, renal dysfunction, any cardiac surgery reoperation, ventilation for more than 48 h, and deep sternal wound infection were assessed and compared. Multivariate logistic regression was used to determine the predictors of major postoperative complications. Patients in the high-CRP group had a significantly higher overall incidence of major postoperative complications, particularly renal dysfunction. In the multivariate logistic regression model, adjusting all the significant univariate predictors, baseline CRP >0.3 mg/dl and preoperative chronic renal failure (CRF) remained as significant independent predictors of major postoperative complications. Conclusions: Elevated preoperative CRP level and/or preoperative CRF indicate increased risk of developing major postoperative complications, particularly acute postoperative renal dysfunction in patients undergoing OPCAB surgery.

Background: With the increase in life expectancy seen throughout the world, the prevalence of degenerative spinal pathology and surgery to treat it has increased. Spinal surgery under general anesthesia leads to various problems and complications, especially in patients with numerous medical comorbidities or elderly patients. For this reason, there is a need for safer anesthetic methods applicable to unhealthy, elderly patients undergoing spinal surgery. Purpose: To report our experience with utilizing fluoroscopy-guided epidural anesthesia in conjunction with conscious sedation in spinal surgery. Patients and Methods: We performed a retrospective review of 111 patients at our institution that received fluoroscopy-guided epidural anesthesia for lumbar surgery from February to September 2018. Patients' records were evaluated to evaluate patient demographics, American Society of Anesthesiology Physical Classification System (ASA) class, and pain numerical rating scores (NRS) preoperatively and throughout their recovery postoperatively. Intraoperative data including volume of epidural anesthetic used, extent of epidural spread, and inadvertent subdural injection was collected. Postoperative recovery time was also collected. Results: The mean age of our patients was 60 years old with a range between 31 and 83 years old. All patients experienced decreases in postoperative pain with no significant differences based on age or ASA class. There was no association between ASA class and time to recovery postoperatively. Older patients (age 70 years or greater) had a significantly longer recovery time when compared to younger patients. Recovery also was longer for patients who received higher volumes of epidural anesthesia. For every 1 mL increase of epidural anesthetic given, there was an increase in the extent of spread of 1.8 spinal levels. Conclusion: We demonstrate the safety and feasibility of utilizing conscious sedation in conjunction with fluoroscopy-guided epidural anesthesia in the lumbar spinal surgery.

Several cases of accidental subdural injection have been reported, but only few of them are known to be accidental intradural injection during epidural block. Therefore we would like to report our experience of accidental intradural injection. A 68-year-old female was referred to our pain clinic due to severe metastatic spinal pain. We performed a diagnostic epidural injection at T9/10 interspace under the C-arm guided X-ray view. Unlike the usual process of block, onset was delayed and sensory dermatomes were irregular range. We found out a dense collection of localized radio-opaque contrast media on the reviewed X-ray findings. These are characteristic of intradural injection and clearly different from the narrow wispy bands of contrast in the subdural space.

Background: Success of transplantation is critically dependent upon the quality of the donor organ and optimal management. Recently, hormonal replacement therapy has been reported to result in rapid recovery of cardiac function and enable significantly more organs to be transplanted, while some other studies show conflicting results. The aim of this study is to comprehensively evaluate changes in basal circulating hormonal levels of the brain-dead organ donors.Methods: We reviewed the records of all brain-dead patients between January, 2004, and June, 2007. Hemodynamic variables, plasma hormone levels were recorded at following time points: admission to the ICU (T1, baseline), 30 minutes (min) after first apnea test (T2), 30 min after second apnea test (T3), before operation for harvesting (T4). Hormonal measurements included cortisol, adrenocorticotrophic hormone, triiodothyronine (T3), thyroxine, free thyroxine, thyroid-stimulating hormone, growth hormone, and testosterone.Results: Nineteen patients were included in this study. Comparisons of hemodynamic parameters and hormonal levels to baseline values revealed no significant changes throughout the study period. When the patients were divided into 2 groups according to the requirement of norepinephrine (either＞0.05 or ≤0.05μg/kg/min), patients requiring ＞0.05μg/kg/min of norepinephrine had T3 level below the normal range at significantly more time points of measurement (7 vs. 0). Conclusions:In this comprehensive assessment of hormonal levels in brain-dead organ donors, we could not observe any significant changes during the ICU stay. Replacement therapy of T3 may be considered in patients requiring ＞0.05μg/kg/min of norepinephrine.
