Proper positioning of pulmonary artery catheter and predicting distal migration of it during cardiopulmonary bypass is important for the prevention of perioperative complication of pulmonary artery rupture. The authors therefore examined the insertion length of pulmonary artery catheter via right internal jugular vein at which catheter tip was advanced to the most proximal position where pulmonary capillary wedge pressure could be obtained. And also the distal migration is measured by comparing the difference between prebypass and postbypass corrected length. Just before bypass, pulmonary artery catheter was arbitrarily receded 5cm for the prevention of spontaneous distal migration and wedging. The subjects were 47 patients who underwent open heart surgery (valve replacement, coronary artery bypass graft) during the period of November, 1992 through April, 1993. The results were as follows. 1) The insertion length of pulmonary artery catheter from skin to the right ventricle inlet, pulmonary artery inlet and pulmonary capillary wedge position were 26.5+/-3.0 cm, 36.8+/-4.9 cm and 46.1+/-5.7 cm respectively. 2) There were no significant statistical correlations between insertion lengths and patient constitutions such as body weight and height(r=0.144, r=0.032). 3) Locations of catheter tips were distributed to the 0.9+/-3.1 cm left to the spinous process, 1.9+/-1.6 cm inferior to the carina ; mostly LLQ of the lung field(51%). 4) During cardiopulmonary bypass, pulmonary artery catheter tips were migrated distally in 93.6% of the cases and the migration lengths were 2.7+/-2.0 cm. 5) There were no major perioperative complications caused by pulmonary artery catheterization. These results suggest that 5 cm withdrawal of pulmonary axtery catheter just before cardiopulmonary bypass can prevent the fatal complication of pulmonary artery rupture owing to its spontaneous distal migration.

Melkersson-Rosenthal (M-R) syndrome consists of a triad of (1) recurrent peripheral facial nerve paralysis which develops alternatively on both sides of face, (2) non-inflammatory facial edema, and (3) furrowed tongue. Since the cause of M-R syndrome is unknown, various forms of therapy have been tried, but there were no conclusive evidence that they altered the course of the disease. A 27-year-old female and a 44-year-old male patient with recurrent facial nerve paralysis were diagnosed with M-R syndrome. We report the two cases of M-R syndrome with the brief review of literatures.

PURPOSE: Magnesium sulfate (MgSO4) is a commonly used drug for eclampsia prophylaxis and the first choice tocolytic agent for preterm labor. Recently it has been reported to have a fetal neuroprotective effect. This study was aimed to evaluate the influence of antenatal magnesium sulfate exposure on perinatal outcomes in very low birth weight infants (VLBWIs) with maternal preeclampsia. METHODS: We conducted a retrospective study of VLBWIs (n=81) with maternal preeclampsia (June 2005 through June 2012), who had been admitted to the NICU at Ewha Womans University Mok Dong Hospital. Clinical characteristics and neonatal complications were analyzed according to the antenatal exposure to MgSO4. Antenatal MgSO4 exposure was the only medication that had been administered up to the period of delivery. RESULTS: Among 81 neonates, 20 neonates were exposed to antenatal MgSO4. Mean gestational age was low in MgSO4 exposed group [29.5+/-2.8 vs. 31.6+/-2.3 weeks (P=0.02)]. The incidence of significant patent ductus arteriosus (S-PDA) was higher in MgSO4 exposed group after adjustment by gestational age (P=0.02). There were no differences between the two groups with regard to rates of respiratory distress syndrome, use of ventilator, retinopathy of prematurity, necrotizing enterocolitis, intraventricular hemorrhage, periventricular leukomalacia and mortality. CONCLUSION: Antenatal MgSO4 exposure was associated with a higher risk of significant PDA in VLBWIs with maternal preeclampsia.

BACKGROUND: Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae are main pathogens of bloodstream infection. We compared the epidemiology of ESBL-producing E. coli and K. pneumoniae. METHODS: From January 2003 through March 2007, we retrospectively investigated the clinical characteristics and comorbidities of patients with bloodstream infection by ESBL-producing E. coli and K. pneumoniae. RESULTS: During the study period, 79 patients (54 with E. coli and 25 with K. pneumoniae) with blood cultures positive for ESBL-producing E. coli or K. pneumoniae were studied. When comparing the source of bloodstream infections, urinary tract infections (UTIs) were more commonly caused by E. coli (24% vs. 0; P=0.007), and respiratory tract and soft tissue infection (36% vs. 15%; P=0.04, 12% vs. 0; P=0.03, respectively) were more commonly associated with K. pneumoniae. Among hospital-acquired bloodstream infection, third-generation cephalosporin was more commonly used in patients with E. coli than patients with K. pneumoniae (81% vs. 24%, P<0.001). Medical devices (central venous catheter and urinary catheter) were more commonly used in patients with K. pneumoniae. CONCLUSION: ESBL-producing E. coli bloodstream infection is more common in urinary tract infections. ESBL-producing K. pneumoniae is more common in respiratory tract infections and in skin and soft tissue infections. In hospital-acquired infections, ESBL-producing E. coli bloodstream infection is more common in biliary tract infection. ESBL-producing E. coli was more commonly associated with prior frequent antibiotics use and K. pneumoniae was more commonly associated with use of medical devices.

PURPOSE: The objective of this survey was to develop an operational plan for breast feeding education. In order to comprehend current breast feeding patterns, we aimed to examine the knowledge, attitude and practices regarding breast feeding of mothers and to compare the data with a similar study done 6 years ago. METHODS: A total of 127 mothers who delivered healthy babies at Ewha Womans University Dongdaemun Hospital were interviewed and asked to complete a survey on their perception of breast feeding during their postpartum stay in the hospital. A follow up phone interview was carried out at 1, 2 and 3 months after delivery and similar questions were asked. RESULTS: At the time of delivery, 96.1 percent of mothers planned to breast feed, including 73.2 percent of exclusive breast feeding and 22.8 percent of mixed feeding. The duration of breast feeding planned was mostly 7-12 months. Breast feeding had been recommended by family members. Between 1-3 months, exclusive breast feeding was maintained at least 50 percent but a large number of mothers who had practiced mixed feeding changed to formula feeding. This trend demonstrates an increase in the rate of breast feeding at 3 months compared to a similar study done in 1999. The main reasons for discontinuing breast feeding were insufficient amount of milk (35.0 percent) and return to work (27.5 percent). CONCLUSION: Breast feeding rate has increased in Korea since 1999 but failure to continue exclusive breast feeding still occurs mainly within the first month after delivery. Breast feeding education should focus on supportive care to mothers practicing mixed feeding.
