This case was an acquired aplastic anemia patient who required a major operation for excision of a mediastinal mass. The authors previewed that the coagulation abnormalities would be developed due to major operation. Thus we decided to monitoring the coagulation function using the thromboelastography during the perioperative period and checked the complete blood count, concommitantly. The total blood volume lost during operation was 1800 ml, so we gave him a transfusion of 10 U's of platelet concentrate, 10 U's of pheretic platelet rich plasma and 5 U's of whole blood. The thromboelastography was a good guide that helped us to avoid excessive treatment of the coagulation abnormalities. We concluded that the thromboelastograhy was a reliable and effective monitoring system at the intraoperative coagulation management.

The endoscopic variceal ligation(EVL) has been adopted as a new treatment for acute hemorrhage from esophageal varices that ranks the highest mortality rate in upper gastrointestinal tract bleedings. This treatment method has good effects for the urgent treatment and eradication of varices from acute variceal bleeding in repeated sessions. We enrolled 34 patients with an acute or chronic variceal bleeding episode at the time of admission in this study from Apr. 8, 1992 to June. 2, 1994. Among 34 patients, there were 31 males and 3 females, at ages between 45-66(mean: 52 years). The incidence of symptoms on admission was 10 in tarry stool, 9 in hematemesis 8 in ascites, 4 in hepatic encephalopathy and 3 in nonspecific symptoms. Varices were eradicated or reduced to grade I in 30(88.2%) of the 34 patients by 4-25 bands (mean: 10.8 bands) in 1-7 EVL sessions(mean: 3.1 sessions). After EVL, there are complicated by active bleeding in 3 patients, dysphagia in 3 patienta and transient chest discomfort in 5 patients but subsided during 24 hours. These results indicated that EVL is a safe method for treatment of bleeding from esophageal varices.

Pheochromocytoma stems from the chromaffin cell and mostly is located in the adrenal medulla. It is an important cause of secondary hypertension due to correction of hypertension by a resection of the tumor. Because it produces and secretes catecholamine, it bothers anesthesiologists with excessive hypertension, tachycardia and arrhythmia during the anesthetic period. Therefore, anesthetic management is directed to avoid these conditions. We report a case of bilateral pheochromocytoma successfully managed intraoperatively with an infusion of nicardipine and an intermittent esmolol injection.

BACKGROUND: Antibiotics are used prophylactically in surgery to prevent postoperative infection. However, antibiotics administered in large doses can cause a bleeding diathesis as a result of platelet dysfunction. We wondered whether these antibiotics might impair platelet function by interfering with the initial step of platelet activation: the binding of agonists to their specific receptors on the platelet surface. METHODS: In 30 patients (male 18, women 12) undergoing primary elective knee arthroscopic surgery, the whole blood coagulation system was prospectively evaluated before, and 10 and 40 minutes after administration of 1 g of augmentin. All patients who had abnormal preoperative coagulation profiles or who received anticoagulant or antiplatelet, antibiotics therapy within 7 days prior to surgery were precluded. RESULTS: At 10 minutes after augmentin administration 25 of 30 patients had a significant impairment in all phases of whole blood coagulation as monitored by thromboelastography. In contrast, three of 30 patients had a significantly decreased coagulation time. Two of 30 patients had no significant changes of TEG variables. TEG variables were restored toward baseline in fourty minutes after augmentin administration. CONCLUSIONS: Augmentin can cause a significant but transient change in the viscoelastic properties of blood. Coagulation parameters of the TEG should be measured prior to augmentin administration to prevent and prospect a bleeding diathesis as a result of platelet dysfunction.

Serological prenatal screening tests are widely used to detect fetal chromosomal abnormalities such as Down and Edward syndromes. Amniocentesis is conducted as a confirmatory test in the screening-positive case. After discovering of presence of fetal cell-free DNA in maternal blood, non-invasive prenatal test (NIPT) coupled with next generation sequencing are performed in abroad. Results of genomics-based NIPT results supplied to Labgenomics laborotory from June, 2013 to August, 2014 were analyzed. Maternal blood samples were collected into specific Cell-Free DNA BCT tube and were transported. The samples were then delivered to Ariosa Diagnostics by FEDEX. Fetal cell-free DNA samples were analyzed using the Harmony test with sequencing of relevant chromosomes and by using the FORTE (fetal-fraction optimized risk of trisomy evaluation) algorism at Ariosa Diagnostics. In all, 149 cases from 28 medical clinics were analyzed. Six subjects were required recollection of samples because of a low fetal DNA fraction in the initially obtained samples. Of these 6 subjects, no sample could be collected from one. Of the remaining 148 cases, 144 had a low risk of trisomy, and 4 had a high risk for Down syndrome, thus providing a positivity percentage of 2.7%. Fetal DNA fraction in the maternal blood samples ranged from 4.2% to 23.7% with a mean value of 12.0%. We have experienced cases with a high risk for Down syndrome with genomics-based NIPT referred to abroad.

BACKGROUND: Epidural anesthesia is becoming an increasingly important aspect of anaesthetic practice because it has many advantages. To achieve the appropriate sedation, various methods have been described. The authors applied the ketamine for this purpose in subanesthetic dose and compared with the midazolam that has been most commonly used for intravenous sedation. METHODS: Fifty-seven adult patients undergoing lower abdominal and extremity surgery who were receiving epidural anesthesia were randomely enrolled into this clinical study. They were allocated to three groups to receive only normal saline (group C), midazolam 0.05 mg/kg (group M) and ketamine 0.5 mg/kg midazolam 0.05 mg/kg (group K) in normal saline 10ml, respectively. Hemodynamic and respiratory measurements were recorded at baseline, 1 minute, 3 minute, 5 minute, 10 minute, 20 minute and 30 minute after sedation. The degree of sedation was assessed by a blinded observer using sedation score. RESULTS: There were no significant differences for hemodynamic and respiratory parameters, but decrements of arterial pressure at 1 minute after sedation were most remarkable in the group M. Sedation was satisfactorily achieved by combination of ketamine and midazolam without significant emergence reaction. CONCLUSIONS: The combination of ketamine and midazolam was judged to be suitable alternative for sedation during epidural anesthesia.
