Lingual tonsillar hypertrophy (LTH) is a rare and dangerous condition in the management of the upper airway. It is not detectable from the history or on routine preoperative physical examination. Enlarged lingual tonsils can cause posterior displacement. A 56 year old man was scheduled for emergency laryngeal microscopic surgery for the removal of a throat foreign body. After the induction of general anesthesia, intubation with a rigid laryngoscope was impossible due to LTH. After recovery of self respiration, the endotracheal tube intubation was possible by the combined use of a laryngoscope, Magil forceps and fiberoptic bronchoscope.

This study was conducted to investigate the choline intake of Korean adults for the purpose of preparing a basal data required for the establishment of choline adequate intake (AI). The subjects of 56 Korean young adults were recruited from college students of 20 to 30 years old in Daejeon city. The aliquots of foods that the subjects ate for one day were collected with use of duplicate food collection method and choline content of one day meal directly was analyzed with the use of enzymatic method. Choline intakes of male subjects were in the range of 353.5 ~ 1222.5 mg and those of female subjects were in the range of 213.1 ~ 722.3 mg. Mean intakes of choline were 658.2 +/- 243.9 mg/day in male subjects and 423.3 +/- 133.6 mg/day in female, therefore choline intake of men was about 200mg higher than that of women. Median value in total subjects was 496 mg, male's median was 608.8 mg, female's median was 419.9 mg. When the subjects were devided into 4 groups by choline intake, as less than 75%, 75 ~ 100%, 100 ~ 125% and over 125% based on choline AI of USA (males: 550 mg, females: 425 mg), there was no significant difference between men (64.3%) and wemen (67.9%) in the distribution of the subjects whose choline intake is under the range of 75 ~ 125% AI of USA. However, 10.7% of men and 21.4% of female had choline intake less than 75% AI of USA while the cases of choline intake higher than 125% AI were 25% in male and 10.7% in female. Thus, it is assumed that female case in choline-deficient state would be two times more than male. When adjusted by body weight, choline intake was 9.5 +/- 3.4 mg/kg in men, 8.1 +/- 3.1 mg/kg in women and 8.8 +/- 3.3 mg/kg in total subjects. And choline intake per 1,000 kcal of men, women and total subjects were 277.1 +/- 78.4 mg, 275.9 +/- 62.1 mg and 276.5 +/- 70.1 mg respectively. From these results, it is suggested that these levels of 276.5 +/- 70.1 mg/ 1,000 kcal or 8.8 +/- 3.3 mg/kg B.W. can be used as a reference value for the establishment of AI of choline for Korean, because overall choline intake of these subjects was not in lower state compared to other nutrients intakes obtained from calculation of the food the subjects had taken.

Objectives: : Tianeptine is an antidepressant that has drawn attention recently. Unlike traditional monoaminergic antidepressants, tianeptine is known to affect glutamate neurotransmission like ketamine. However, there has been paucity of studies investigating the role of tianeptine on glutamate transporters, especially excitatory amino acid transporter type 3 (EAAT3). Methods: : After expression of EAAT3 by intracellular injection of EAAT3 mRNA, we investigated the effect of tianeptine on the activity of EAAT3, by measuring membrane current in response to L-glutamate administration using Xenopus oocyte expression system and two-electrode voltage clamps.. Results: : Tianeptine (1mM for 72h) significantly reduced Vmax (6.9±0.6 vs. 4.8±0.3mC, n=14-22, p<0.05) without changing Km (27.0±7.6 vs. 23.3±4.9mM, n=14-22, p=0.72). Conclusion : When tianeptine was exposed for 72h, it decreased the activity of EAAT3 in a concentration-dependent manner (1-100mM). Our results suggest that tianeptine decreases EAAT3 activity by reducing the available number or turnover rate of EAAT3.

BACKGROUND: This study was designed to evaluate the efficacy and safety of midazolam premedication administered by a jet-injector in pediatric patients. METHODS: Children undergoing outpatient surgery were randomized into three groups: intravenous induction with thiopental sodium (control group, n = 20), oral midazolam premedication (PO-med group, n = 20) or midazolam premedication using a jet-injector (Jet-med group, n = 20). In the PO-med and Jet-med group patients, anesthetic induction was performed by sevoflurane inhalation and an intravenous catheter (IVC) was inserted after the children had been anesthetized by sevoflurane inhalation. For the control group patients, an IVC was placed in the preoperative holding area. Agitation scores were recorded in the preoperative holding area and recovery room. Anesthesia times and the views of the medical staff concerning the technique benefits were also noted. Patients and parents were interviewed on the following day. RESULTS: Maximum agitation scores in the preoperative holding area and during separation with parents were significantly lower in the PO-med and Jet-med groups. The induction time was significantly longer in the PO-med and Jet-med groups. No statistically significant differences were found for the recovery characteristics. Though interviews with patients and parents produced similar results for patients in each group, the medical staff satisfaction levels were significantly higher for patients in the PO-med and Jet-med groups. CONCLUSIONS: The findings of this study suggest that the application of the jet-injector for midazolam premedication may be clinically useful in children who do not have an IVC. The use of the jet-injector could be a substitute for the oral route for midazolam administration.

BACKGROUND: Magnesium sulfate (MgSO4) is the first-line therapy for managing preeclampsia in obstetrics. Its perioperative administration has been proved to be an effective analgesic adjuvant, which we investigated in parturients undergoing Cesarean section (C-sec). METHODS: A retrospective chart review examined 504 parturients who underwent C-secs between June 2006 and August 2010, including normal parturients (group N, n = 401) and those diagnosed with preeclampsia (group P, n = 103). A postoperative numeric rating scale (NRS) was used to assess pain, and the number of rescue analgesic administrations and frequency of transfusions were investigated. Perioperative magnesium concentrations were recorded for patients in group P. RESULTS: Patients in group P had longer operation and anesthesia times, and more postoperative admission days than those in group N. The NRS of pain was significantly lower in group P at postoperative day (POD) 1 (4 vs. 5, P < 0.001), and the frequency of rescue drug administration was lower in group P at POD 1 (36.0% vs. 80.3%, P < 0.001) and POD 2 (9.7% vs. 21.1%, P = 0.005) than in group N. Red blood cell transfusions were given more frequently in group P (21.4% vs. 2%, P < 0.001). Pre- and postoperative serum magnesium concentrations in group P were 2.2 (0.5) and 2.1 (0.6) mmol/L, respectively. CONCLUSIONS: Postoperative pain after C-sec was less severe and intravenous patient-controlled analgesia was more efficacious in the preeclampsia group than in the non-preeclampsia group. These findings likely resulted from peripartum intravenous MgSO4 administration in the preeclampsia group.

BACKGROUND: Lung transplantation (LTx) is an effective treatment for end stage lung disease. However, the shortage of donor lungs has been a major limiting factor to increase the number of LTx. Ex vivo lung perfusion (EVLP) is a currently approved method to evaluate lung function and to repair donor lung with poor function. The purpose of this study was to develop EVLP system in pig model and to maintain lung function during 4 hours of EVLP. METHODS: Bilateral lung blocks were harvested from five 40 kg pigs. These blocks were applied in EVLP perfused with 37degrees C Steen solution. We performed arterial blood gas (ABG) analyses before death and also every 1 hour for 4 hours after application of EVLP and calculated oxygen capacities (OC) using the results of ABG. We also calculated pulmonary vascular resistance (PVR) and peak airway pressure (PAP) every 1 hour for 4 hours. After EVLP procedure, we excised specimens for pathologic review. RESULTS: We found that OC gradually decreased during the 4 hour period of EVLP; however, no statistically significant difference was obtained. PVR declined sharply after 1 hour of EVLP (P=0.031) and then remained constant for 3 hours. PAP significantly increased after 3 hours (P<0.0001). Pathologic investigations revealed various findings from normal lung to severe pulmonary edema. CONCLUSIONS: On the results of this study, we could preserve the lung function for 4 hours using EVLP. We conclude that application of EVLP in clinical setting can make more donor lungs available for LTx. However, we also understand that more studies and training are needed in clinical practice.

BACKGROUND: Hydroxyethyl starch (HES) solutions are used as plasma expanders for correcting hypovolemia, but can lead to impaired coagulation. We evaluated the changes in hematological and hemostatic profiles with three types of HES. METHODS: Patients were randomized to receive volume replacement with 10% pentastarch 260/0.45 in 0.9% saline (Group-PEN, n = 25), 6% tetrastarch 130/0.4 in 0.9% saline (Group-TET(S), n = 25), or 6% tetrastarch 130/0.4 in a balanced electrolyte solution (Group-TET(B), n = 25). Coagulation was assessed using rotational thromboelastometry (ROTEM(R)) and other laboratory tests were performed, including measurements of hematological and hemostatic parameters and electrolytes. RESULTS: Post-operative ROTEM(R) parameters changed toward hypocoagulable states in all groups. The post-operative parameters of EXTEM and FIBTEM were more impaired in Group-PEN than in Group-TET(B). The percentage change in INTEM clot formation time (P = 0.004) and alpha-angle (P = 0.003) were smaller in Group-TET(S) and Group-TET(B) than in Group-PEN. The percentage change in the FIBTEM maximum clot firmness was greatest in Group-PEN (P = 0.011). The international normalized ratio of prothrombin time (P < 0.001) and the activated partial thromboplastin time (P < 0.001) were significantly prolonged in Group-PEN compared to those of Group-TET(B). CONCLUSIONS: The 6% HES 130/0.4 in a balanced electrolyte solution seemed to have less of an impact on blood coagulation than the 10% HES 260/0.45. No differences in hemostatic profile were observed between the balanced electrolyte and saline-based 6% HES 130/0.4.

Anaphylaxis is an acute and fatal systemic allergic reaction to an allergen, and it can be an unpredictable and life-threatening cause during anesthesia. Latex is the second most common cause of anaphylaxis following the use of neuromuscular blocking agents during general anesthesia or surgery. We report on a 67-year-old male who had undergone surgery under general anesthesia without any problem but who presented with severe intraoperative anaphylaxis to latex surgical gloves. This case emphasizes the need for anesthesiologists to quickly diagnose and properly manage an allergic reaction in patients under general anesthesia.

BACKGROUND: Using rotational thromboelastometry (ROTEM) analysis, we investigated the difference in blood hemostasis, based on the primary anesthetic agents used during general anesthesia. METHODS: Sixty-six adult patients scheduled for elective ophthalmic surgery under general anesthesia were evaluated with regard to changes in each parameter in INTEM, EXTEM, and FIBTEM analyses. The patients received intravenous anesthesia with propofol and remifentanil (TIVA group) or inhalation anesthesia with sevoflurane (SEVO group). The ROTEM tests were performed 10 min before starting anesthesia and 1 h after finishing anesthesia. The INTEM and EXTEM analyses included the clotting time (CT), clot firmness time (CFT), alpha angle (alpha), and maximum clot firmness (MCF). The FIBTEM analyzed only MCF. Maximum clot elasticity (MCE) was calculated by (MCF x 100) / (100 - MCF). The platelet component of clot strength was calculated as follows: MCE(platelet) = MCE(EXTEM) - MCE(FIBTEM). RESULTS: The preoperative and postoperative parameters (CT, CFT, alpha, and MCF) in the INTEM, EXTEM, and FIBTEM analyses were not significantly different between the two groups. The MCE(platelet) also did not show a significant difference. CONCLUSIONS: Presuming that the ophthalmic surgery had a minimal traumatic effect, we conclude that both anesthetic agents cause negligible changes in ROTEM analyses postoperatively.
