Ganglion impar block is a known useful method of controlling perineal cancer pain. Moreover, this method may be suitable for hyperhidrosis because the visceral cancer pain signal and sweating are transmitted by the same sympathetic chain. We experienced a patients who had suffered from systemic hyperhidrosis especially in the sacral and buttock area. She also had long-standing diabetes mellitus and chronic renal failure. Her excessive sweating occurred during hemodialysis. We treated this patients using a ganglion impar block and achieved a good result.

General anesthesia is the most common method used for operations and volatile anesthetics are commonly used for general anesthesia. Moreover, it is known that the newly developed volatile anesthetics are safe in liver and kidney. However, inorganic fluoride levels increase with anesthetic time and increase the possibility of renal toxicity and repeat a anesthesia in short term period increase the possibility of hepatic failure. We experienced 2 cases who received general anesthesia with volatile anesthetics more than 50 times without any organ failure. Here, we review the anesthetic records and preoperative laboratory findings of each operation.

Partial airway obstruction is common in anesthesia and has several causes, but total airway obstruction is rare and may result in severe complications if not corrected early. We experienced total airway obstruction of a dependent bronchus by cancer materials during pneumonectomy and removal of these materials with Fogarty and Foley catheters took considerable time. PaCO2 increased to more than 170 mmHg and pH decreased to less than 7 at 1 hour after obstruction. But, no metabolic derangement or neurologic sequelae were observed after the operation.

Background: There are several advantages of low flow anesthesia including safety, economics, and eco-friendliness. However, oxygen concentration of fresh gas flow and inspired gas are large different in low flow anesthesia. This is a hurdle to access to low flow anesthesia. In this study, we aimed to investigate the change in inhaled oxygen concentration in low flow anesthesia using oxygen and medical air. Methods: A total of 60 patients scheduled for elective surgery with an American Society of Anesthesiologist physical status I or II were enrolled and randomly allocated into two groups. Group H: Fresh gas flow rate (FGF) 4 L/min (FiO₂ 0.5). Group L: FGF 1 L/min (FiO₂ 0.5). FGF was applied 4 L/min in initial phase (10 min) after intubation. After initial phase FGF was adjusted according to groups. FGF continued at the end of surgery. Oxygen and inhalation anesthetic gas concentration were recorded for 180 min at 15 min interval. Results: The inspired oxygen concentration decreased by 5.5% during the first 15 min in the group L. Inspired oxygen decreased by 1.5% during next 15 min. Inspired oxygen decreased by 1.4% for 30 to 60 min. The inspired oxygen of group L is 35.4 ± 4.0% in 180 min. The group H had little difference in inspired oxygen concentration over time and decreased by 1.8% for 180 min. Conclusions The inspired oxygen concentration is maintained at 30% or more for 180 min in patients under 90 kg. Despite some technical difficulties, low flow anesthesia may be considered.

Air embolism can occur during central venous catheter removal. We encountered a patient diagnosed with cerebral air embolism associated with the removal of an internal jugular venous catheter. The patient was 65 years old and was admitted to the intensive care unit due to pneumonia. He had a catheter placed in the right internal jugular vein. Five days thereafter, the catheter was removed in semi-Fowler's position using the Valsalva maneuver. Immediately after the catheter removal, the patient became pale, felt dyspneic, lost consciousness and exhibited seizure activity. A neurological examination, revealed left upper arm (grade I) and lower leg paralysis (grade II) as well as left facial palsy. A brain computed tomogram showed that, air was trapped in the cavernous sinus. In diffusion weighted magnetic resonance imaging, signal changes were reported in the right frontal cortex, indicating acute cerebral infarction. Hyperbaric oxygen therapy and ventilatory support with synchronized intermittent mandatory ventilation mode was applied. Twenty days thereafter, consciousness and motor functions were recovered completely except for mild weakness of the upper arm (grade IV).

BACKGROUND: The microRNA (miRNA) pathway has emerged as one of the biologic pathways implicated in stem cell regulation. miRNA is a noncoding, single-stranded RNA consisting of 20-25 nucleotides that inhibits the protein production at the step of translation. The molecular effects of lidocaine and procaine on adipose stem cells were investigated by examining RNA expression array. METHODS: Adipose stem cells were isolated from a prior abdominal liposuction procedure. The human adipose stem cells were cultured and then added to a mixture of 1 ml of culture medium plus 1 ml of 2% lidocaine or 2% procaine for the duration of 30 minutes. The expression levels of miRNAs were estimated by using peptide nucleic acid (PNA)-miRNA array analysis throughout the denaturation and hybridization processes after the isolation of miRNA. The miRNAs detected by microarray that either decreased by half fold or increased by 1.5 fold from the control level were interpreted as significant. RESULTS: According to microarray analysis there were 61 miRNAs in total, and no miRNA had decreased expression levels. The stem cells treatment with lidocaine showed 4 alteration of expression with miR-9a* (1.53 fold), miR-29a (1.64 fold), miR-296-5p (1.64 fold) and miR-373 (1.94 fold). The stem cells treated with procaine showed 32 miRNAs that were significantly up-regulated with a range of 1.5 to 2.06 fold. They were stem cell differentiation-related miRNAs, apoptosis and cell cycle-associated miRNAs, immunity-associated miRNAs and hormonal response-related miRNAs. CONCLUSIONS: Lidocaine and procaine affect the miRNA expression on adipose stem cells and the effect of procaine is more marked than that of lidocaine.

At the confluence of the superior, anterior, and middle mediastinum are the middle portion of the superior vena cava, the tracheal bifurcation, the main pulmonary artery, the aortic arch, and parts of the cephalad surface of the heart.Tumors in this region can cause compression and obstruction of tracheobronchial tree in the region of tracheal carina even though there is no sign and symptom related to respiratory failure in preinduction period.We experienced airway (tracheal) obstruction due to mechanical compression by mediastinal mass during anesthetic induction.She is 24-year old who had no symptom of respiratory distress in preinduction period.
