The number of sedations performed for diagnostic and therapeutic procedures that do not require general anesthesia is increasing. As most sedations are performed by non-anesthesiologists, safety is has become a critical issue in light of recent adverse outcomes reported in the media. To ensure the safety of patients undergoing sedation for minor procedures, standards regarding patient selection, education, drugs, equipment, facilities, sedation protocols, recovery, and monitoring should be developed and publicized as they have been in the US and European countries. Guidelines developed regarding sedation and analgesia are similar and share their most important goal: patient safety. Any barriers that interfere with achieving this goal should be identified and eliminated. A Korean version of sedation guidelines should be developed. Guidelines that have both the clinical integrity of evidence and consideration of the real world should be developed and enforced.

BACKGROUND: The aim of this study is to evaluate the influence of immunosuppressants on in-hospital mortality from sepsis. METHODS: Using data of the Health Insurance Review & Assessment Service, we collected data from patients who were admitted to the hospital due to sepsis from 2009 to 2013. Based on drugs commonly used for immunosuppression caused by various diseases, patients were divided into three groups; immunosuppressant group, steroid-only group, and control group. Patients with no history of immunosuppressants or steroids were assigned to the control group. To identify risk factors of in-hospital mortality in sepsis, we compared differences in patient characteristics, comorbidities, intensive care unit (ICU) care requirements, and immunodeficiency profiles. Subgroup analysis according to age was also performed. RESULTS: Of the 185,671 included patients, 13,935 (7.5%) were in the steroid-only group and 2,771 patients (1.5%) were in the immunosuppressant group. The overall in-hospital mortality was 38.9% and showed an increasing trend with age. The steroid-only group showed the lowest in-hospital mortality among the three groups except the patients younger than 30 years. The steroid-only group and immunosuppressant group received ICU treatment more frequently (p < 0.001), stayed longer in the hospital (p < 0.001), and showed higher medical expenditure (p < 0.001) compared to the normal group. Univariate and multivariate analyses revealed that age, male gender, comorbidities (especially malignancy), and ICU treatment had a significant effect on in-hospital mortality. CONCLUSIONS: Despite longer hospital length of stay and more frequent need for ICU care, the in-hospital mortality was lower in patients taking immunosuppressive drugs than in patients not taking immunosuppressive drugs.

Aspiration pneumonitis and aspiration pneumonia are clinical syndromes caused by aspiration. These conditions are clinically significant due to their high morbidity and mortality. However, aspiration as a preceding event are often unwitnessed, particularly in cases of asymptomatic or silent aspiration. Furthermore, despite the difference in treatment approaches for managing aspiration pneumonitis and aspiration pneumonia, these two disease entities are often difficult to discriminate from one another, resulting in inappropriate treatment. The use of unclear terminologies hinders the comparability among different studies, making it difficult to produce evidence-based conclusions and practical guidelines. We reviewed the most recent studies to define aspiration, aspiration pneumonitis, and aspiration pneumonia, and to further assess these conditions in terms of incidence and epidemiology, pathophysiology, risk factors, diagnosis, management and treatment, and prevention.

Seizure is the second most common neurologic complication after liver transplantation and may be caused by metabolic abnormalities, electrolyte imbalance, infection, and immunosuppressant toxicity. A 61-year-old male patient underwent liver transplantation due to hepatitis B virus-related liver cirrhosis with portal systemic encephalopathy. The immediate postoperative course of the patient was uncomplicated. However, on postoperative day (POD) 6, weakness developed in both lower extremities. No abnormal findings were detected on a brain computed tomography (CT) scan on POD 8, but a generalized tonic clonic seizure developed which was difficult to control even with multiple antiepileptic drugs. A follow-up brain CT scan on POD 15 showed a 2.7 cm sized acute intracranial hemorrhage (ICH) in the left parietal lobe. The patient's mental status improved after 2 months and he was able to communicate through eye blinking or head shaking. Our case reports an acute ICH that manifested into a refractory seizure in a patient who underwent a liver transplant.

Upper extremity deep vein thrombosis (UEDVT) is relatively uncommon and superior vena cava (SVC) filter placements are not often encountered due to strict indication. A 33-year old male with underlying protein C/S deficiency and secondary liver cirrhosis was admitted because of hematemesis. The patient was conservatively managed, but underwent elective splenectomy to prevent aggravation of gastric varix. During postoperative care, the patient underwent cholecystectomy for acalculous cholecystitis. During the postoperative course, UEDVT was detected and heparinization was initiated. The patient experienced repeated attacks of severe dyspnea, which was accompanied by chest pain that lasted for 3 to 10 minutes. Repeated episodes of pulmonary thromboembolism were suspected and SVC filter was placed. Warfarin treatment was initiated and the SVC filter was removed about one month later. The case highlights the clinical significance of UEDVT and reports rare case of SVC filter placement. Intensivists should have comprehensive understanding of UEDVT and its management.

BACKGROUND: Thoracic epidural analgesia is the mainstay of postoperative pain control after thoracotomy. Usually the epidural catheter is blindly inserted and secured without confirming the tip position. The purpose of this study was to determine the influence of epidural approach angle on the position of the thoracic epidural catheter tip. METHODS: 129 patients scheduled for thoracotomy were enrolled. Patients were randomized into two groups: narrow angle group and wide angle group. The epidural needle was inserted at the skin of T8-9 level in both groups. In the narrow angle group the epidural space was approached at T7-8, whereas in the wide angle group the epidural space was approached at T6-7. After epidural space confirmation, a B-D nylon multi-hole epidural catheter was threaded 8cm into the epidural space. The epidural catheter tip position was assessed using a small amount of radiocontrast dye under fluoroscopy. RESULTS: The mean (95% confidence interval) position of the catheter tip was the mid-body of T5 (T5-6 - T5 upper body) in the narrow angle group and T3-4 (mid-body of T4-T3 lower body) in the wide angle group (P = 0.037). CONCLUSIONS: When approaching the thoracic epidural space by a wide angle, we can place the epidural catheters at a higher level because of a straighter threading.

The use of extracorporeal membrane oxygenation (ECMO) in patients with severe hypoxemia refractory to conventional ventilation has recently gained attention due to recent reports that highlighted its potential benefit. This report presents a case of acute onset acute respiratory distress syndrome (ARDS) with severe hypoxemia in the operating room that showed significant improvement after applying ECMO in the intensive care unit. Although the oxygen saturation decreased to as low as 50% before the application of ECMO, at no time did the patient show hypotension or decreased cardiac output. The patient improved within 48 hours of ECMO and recovered with no major complications or neurologic sequelae. Our case shows that ECMO is a valuable and viable option in ARDS with severe refractory hypoxemia.

Hypertension is a rare but well-documented manifestation of neuroblastoma. This is a case in which a hypertensive 8 month-old male with a large left adrenal mass was diagnosed as pheochromocytoma and prepared for surgery with alpha adrenergic blockers and beta adrenergic blockers. Vital signs prior to induction of anesthesia and during surgery also mimicked pheochromocytoma but pathologic examinations revealed neuroblastoma. Laboratory findings also supported pheochromocytoma taking into account the fact that hypertension is rare in neuroblastomas.

OBJECTIVE: To evaluate the effects of the reactive oxygen species (ROS) generated with a xanthine(X) and xanthine oxidase (XO) system on sperm function, the change of sperm characteristics, lipid peroxidation, and DNA fragmentation in bovine spermatozoa. MATERIALS AND METHODS: ROS were produced using a combination of 100 micrometer X and 50 mU/ml XO. The ROS scavengers: superoxide dismutase (SOD)(200mu/ml) and catalase (500mu/ml) were also tested. Spermatozoa were incubated for 2 hours in BWW medium with a combination of X-XO supplemented with or without ROS scavengers at 37degrees C under 5% CO2 incubator. Sperm movement characteristics by CASA (computer-aided sperm analysis), HOST (hypoosmotic swelling test), Ca-ionophore induced acrosome reaction, malondialdehyde formation for the analysis of lipid peroxidation, the percentage of DNA fragmentation using the method of TdT-mediated nick end labelling (TUNEL) by flow cytometry were determined after 2 hours incubation. RESULTS: The action of ROS on bovine spermatozoa resulted in a decreased in capacity for sperm motility, Ca-ionophore induced acrosome reaction and membrane integrity, an increased in malondialdehyde formation and the percentage of sperm with DNA fragmentation. In the effects of antioxidant, catalase completely alleviated the toxic effects induced by the ROS in terms of sperm function and characteristics, however SOD exhibited no capacity to reduce the toxic effects. CONCLUSION: The ROS can induce significant damages to sperm functions and characteristics. The useful ROS scavengers can minimized the defects of sperm function and various damages of spermatozoa.
