42-year-old woman who had suffered cardiac arrest because of hypovolemic shock was intractable to conventional cardiopulmonary resuscitation (CPR). After 34 minutes of CPR, we decided to start extracorporeal membrane oxygenator (ECMO) in order to provide adequate cerebral and coronary perfusion. She received hysterectomy and bleeding control for 2 hours 30 minutes, and three hours after the operation, she weaned from the 362 minutes ECMO support successfully and was extubated 12 hours after ECMO weaning on postoperative 1st day. She revealed no neurologic deficit on neurologic examination and electroencephalography. Her cardiac function was decreased when the initial ECMO support was started, but improved into normal status. She suffered from skin burn on defibrillation site, generalized myalgia, and ileus, but was discharged from the hospital without major complications on postoperative 17th day. Extracorporeal cardiopulmonary resuscitation (ECPR) in patients who did not respond conventional CPR can be a feasible option in selected patients.

PURPOSE: This study was done to identify the effects of a Self-discovery Program for elementary school students. The study consisted of two phases: Developing the program and evaluating its effectiveness. METHODS: Forty six students who were in elementary school in B city participated in a survey, which was carried out from May 25 to July 15, 2010. To test the effects of the Self-discovery Program, the participants were divided into two groups, an experimental group (n=23) and a control group (n=23). The research design used in this study was a non-equivalent control group pretest-posttest research design. Data were analyzed by using chi2-test, t-test and ANCOVA with the SPSS/WIN 14.0 program. RESULTS: Significant differences were found in scores for self-esteem (t=2.60, p=.006), stress (F=18.65, p<.001) and depression (F=23.88, p<.001) between the experimental group and the control group. CONCLUSION: The results indicate that Self-discovery Program should be used with children to help them and to improve their mental health.

OBJECTIVES: Hand-to-face contact (HFC) is the major route for the self-inoculation of pathogens. This study aimed to describe the characteristics of HFC behaviors among Korean adults during indoor activities. METHODS: Thirty participants were enrolled in the study, and 2 hours of videotaped data were collected from each participant. Contact data were recorded by examining the frequency and duration of HFC on the videos. Three training sessions were conducted for 2 readers to ensure the accuracy and reliability of videotape reading. Re-reading and verification of selected video data were performed to confirm intrapersonal and interpersonal validity. Contact exposure (CE) was determined by multiplying the contact frequency (CF) by the contact duration (CD) to quantify the intensity of contact during the observation time (2 hours). RESULTS: A total of 3,007 HFCs (1,305 mucous membrane contacts and 1,702 non-mucous membrane contacts) were observed for 60 person-hours. The median CF (person/2 hr) of the mucous membranes (eye; 4.0, nose; 15.5, mouth; 16.5) was 39.5/person and the median total CD was 177.0 sec/person. The median CE (frequency-duration/sec/person) was 5,795.0 (mouth: 1,356.0, nose: 600.0, eye: 57.5). CONCLUSIONS This study showed that the mouth and nose were the most frequent exposure sites for HFC. Avoiding habitual HFC, awareness of self-inoculation by HFC, and vigorous hand hygiene should be strengthened to prevent the spread of infections.

Objectives: The aim of this study was to describe the characteristics of hand-to-environmental contact (HEC) and to identify the factors influencing HEC behavior in Korean adults’ indoor daily life. Methods: Thirty participants were enrolled from January 14 to February 12, 2018 after providing informed consent for being videotaped. Data were collected by recording their indoor daily lives for 2 hours, resulting in 4,732 HEC cases. To ensure the accuracy and reliability of the HEC readings, 3 training sessions were conducted for the videotape readers. Rereading and verifying randomly selected data ensured the validity of intra- and inter-reader readings. Results: The most frequent contact items were phones, papers, computer accessories, and furniture surfaces. The contact density (frequency-duration/min) was highest for category II (items occasionally shared by others, 56.8), followed in descending order by category I (items for individual use, 35.9), and category III (public use items, 3.4). Significant differences in contact density were found according to participants’ demographic characteristics. Conclusion As mobile phones were the most frequent contact item, regular and strict mobile phone cleansing or disinfection strategies are needed, in addition to preventative measures taken for category II and III items. Avoiding sharing personal items with others, refraining from unnecessary HEC, and maintaining strict hand hygiene are recommended.

Objectives: This study aimed to develop a valid social contact survey instrument and to verify its feasibility for use among Korean adults. Methods: The Delphi technique was used to develop an instrument to assess social contacts, which was then applied in a cross-sectional pilot study. A panel of 15 medical professionals reviewed the feasibility and validity of each item. The minimum content validity ratio was 0.49. Thirty participants used the developed measure to record contacts during a 24-hour period. Results: After a systematic review, the survey instrument (parts I and II) was developed. Part I assessed social contact patterns over a 24-hour period, and part II assessed perceptions of contacts in daily life and preventive behaviors (hand hygiene and coughing etiquette). High validity and feasibility were found. In the pilot study, the 30 participants had a combined total of 198 contacts (mean, 6.6 daily contacts per person). The participants’ age (p=0.012), occupation (p<0.001), household size (p<0.001), education (p<0.001), personal income (p=0.003), and household income (p<0.001) were significantly associated with the number of contacts. Contacts at home, of long duration, and of daily frequency were relatively likely to be physical. Assortative mixing was observed between individuals in their 20s and 50s. Contact type differed by location, duration, and frequency (p<0.001). Conclusions The developed social contact survey instrument demonstrated high validity and feasibility, suggesting that it is viable for implementation.

BACKGROUND: The stimulation and selection of an effective acupoint is important for producing effective analgesia in electraoacupuncture. This study examined the effect of electroacupuncture to different acupoints and investigated the effective acupoint for ankle-sprained pain in rats. METHODS: A Sprain was produced by manually overextending the lateral ligament of the right ankle in rats. Electrical stimulation was delivered individually to five acupoints: bilateral Yangno (SI6s), contralateral Zusanli (ST36), Hapko (LI4) and Sanyinjiao (SP6). The level of pain evoked by ankle sprain was measured by the stepping force of the sprained paw during walking at pre-sprain and 24 hrs after the sprain. The effect of electroacupuncture was evaluated by the % full recovery of the stepping force at 1, 2, 4 hr after terminating electroacupuncture. RESULTS: Electrical stimulation to SI6 and ST36 among the five acupoints produced a significant increase in the % full recovery of the stepping force of the ankle-sprained paw during walking. CONCLUSIONS: The effective acupoints for electroacupuncture on ankle-sprained pain in rats is SI6 and ST36. These points are relatively specific to ankle-sprain. It is important to select the appropriate acupoint for effective electroacupuncture-induced analgesia.

BACKGORUND: The objective of this study was to investigate the conditions required for tracheal intubation and the responses to intubation after the administration of a high concentration of sevoflurane- N2O-O2 for vital capacity rapid inhalation induction (VCRii) without muscle relaxant. We compared those with propofol-N2O-O2-vecuronium induction. METHODS:Fifty ASA physical status i or ii adult patients without airway abnormalities who were scheduled for elective surgery requiring endotracheal intubation were randomly allocated to receive either propofol 6g/ml target controlled infusion-N2O 4 L/min-O2 2L/min-vecuronium 0.12mg/kg iv (group PV) or 8% sevoflurane-N2O 4 L/min-O2 2L/min without muscle relaxant (group SO). Vecuronium was injected ninety seconds after starting propofol infusion in group PV. Group SO patients were coached on how to perform vital capacity breathing and the breathing circuit was primed for 2 minutes. Five minutes after the administration of induction agents, intubation was attempted. intubation conditions, arterial blood pressure (BP) and heart rate (HR) changes accompanying both induction techniques were monitored. RESULTS: The time to loss of consciousness for group SO was significantly shorter (41.0+/-15.0 sec vs 81.8+/-25.8 sec, P = 0.000). intubation was successful in 24 out of 25 patients (96%) in group PV and 25 out of 25 patients (100%) in group SO, and clinically acceptable intubating conditions were obtained in 23 of the 25 patients (92%) in group PV and 21 of the 25 patients (84%) in group SO. Significant decreases in BP from baseline were observed before intubation in both groups. The increase in BP at 1min after intubation was significantly greater in group PV. HR did not differ in the two groups. CONCLUSiONS: The intubation conditions after sevoflurane-N2O-O2 without muscle relaxant were similar to those produced after propofol-N2O-O2-vecuronium. Sevoflurane-N2O-O2 VCRii is a useful alternative technique for tracheal intubation when muscle relaxant should be avoided.
