BACKGROUND: Cardiopulmonary resuscitation (CPR) is one of the most important medical procedures. However, we could not find any survival rates from in-hospital cardiopulmonary resuscitation in Korea. The objective of this study was to report outcomes according to a Utstein template for in-hospital CPR and to use this report as basic material to enhance our CPR skills and outcome. METHODS: We reviewed all medical records of arrest cases in our hospital in 2001, which were coded as CPR, care for arrest, defibrillation/cardioversion, and Ambu. The data was summarized and analyzed in Utstein style. Most of the data was described in percentage, and the t-test was used to compare survival rate by sex. A P-value below 0.05 was considered significant. RESULTS: In 2001, 218 patients was resuscitated in our hospital and 53 patients (24.3%) survived after CPR. Their mean survival was 10 days. Twenty-seven victims died within the first 24 hours after resuscitation. Nobody was discharged alive from our hospital. The time interval from collapse to CPR was 1.7 minutes, to intubation, 5.62 minutes, to epinephrine injection 7.4 minutes and to defibrillation, 23 minutes. Glascow coma scale and cerebral performance category were less than 8 and 4 for a majority of patients. CONCLUSIONS: In our hospital, we had a low survival rate and quality of life. To improve outcome, we should prepare a better education program and more equipment and well-trained personnel for CPR.

BACKGROUND: Several reports have indicated that there are fewer postoperative complications after using a smaller spinal needle in young patients. However, no comparative report has been issued on the incidences of postoperative complications after using differently sized spinal needles for spinal anesthesia in elderly patients. Here, we compared a 22 G Quincke needle with a 25 G Quincke needle in elderly patients and investigated postoperative complications. METHODS: Fifty patients, aged over 60 years presented for an elective urological operation. Patients were randomized into two groups to receive spinal anesthetics using a 22 G Quincke needle (group L) or a 25 G Quincke needle (group S). The incidences of postdural puncture headache (PDPH), backaches, and the outcomes of spinal anesthesia were compared between the two groups. RESULTS: Two patients in group L and one in group S developed PDPH postoperatively with no significant statistical difference between the two groups. Four patients suffered backache in group L and two in group S again without significance. But the number of puncture attempts was significantly higher in group S. CONCLUSION: In conclusion, postoperative complications were similar for both groups. However, spinal anesthesia was performed more easily when using a larger spinal needle. Therefore, we recommend that a larger spinal needle be used when difficult spinal anesthesia is anticipated in elderly patients.

The purpose of this study was to investigate current status of sedation training for the residents in pediatric dentistry training institutions and opinions about continuing education after the residency program.
Surveys were sent to 18 pediatric dentistry training institutions by e-mail, and the responses were collected and analyzed. Most of the sedation education period for the residents were the 1st-year education (61.1%) and 1 - 3 years of integrated education (55.6%). In terms of an externship, 5 institutions (27.8%) sent their residents to the department of anesthesiology. Second half of the 1st year (50%) was the highest for a resident to use sedation for the first time. The period of supervisor participation varied from not participating at all to whole time throughout the residency program. The sedation training is conducted at all training institutions, but there were variations in the experience that a resident can gain.
All training institutions agreed on the necessity of continuing education of the sedation, but there were various opinions regarding time, method, and the period of review course. Overall, this study suggested that continuing education should be consisted of 1 - 2 hours of didactic education every year and clinical skills and simulation training in every 2 - 3 years.

Pregnancy induces significant anatomical and physiological changes in the mother. Many pregnant women need dental treatment due to poor oral hygiene related to pregnancy. However, most dentists are reluctant to provide, and most pregnant women are reluctant to receive, dental treatment during pregnancy. Theoretically, maternally administered drugs are transferred to the fetus. Depending on the types of drugs and the stage of pregnancy, the effects of drugs on the mother, as well as the fetus, may vary. Local anesthetics are the most widely used in dental treatment. It is, therefore, important to understand the potential effects of local anesthetics during pregnancy. In this review, we will focus on the maternal and fetal effects of local anesthetics widely used in dental treatment with consideration of the use of local anesthetics during pregnancy.

BACKGROUND: In pediatric anesthesia, a method using deliberate endobronchial intubation and auscultation has been used for proper endotracheal tube depth. Tube size, however, may influence on auscultation for air leak between the tube and main bronchus. We attempted to ascertain whether the uncuffed tracheal tube (TT) size affects verifying tube placement by auscultation in children. METHODS: In 23 children, we measured the distance from the carina to the tip of a tube when the first auscultatory sound could be detected on the left chest and when the breathing sound of both chests equalized during withdrawal from right main bronchus. Then, we compared them with those of either a one-size larger or a one-size smaller tube. RESULTS: The distance from the carina to the tip at the first sound was significantly longer in the smaller tracheal tube (1.8 cm vs 1.5 cm, P = 0.01). The tube tip at the equalized breath sounds was 0.6 cm below the carina in both tubes. CONCLUSIONS: These results suggest that detecting endobronchial intubation may be more difficult when using uncuffed tracheal tubes with one-size smaller tube and that auscultation with deliberate bronchial intubation can place the uncuffed TT deeper than an intended depth.

BACKGROUND: Incorrect positioning of central venous catheter leads to serious complications. To prevent these complications, catheter tip should be at the superior vena cava and right atrial junction. METHODS: We studied 60 right internal jugular catheterizations in infants and children undergoing surgery for congenital heart disease. To confirm the optimal depth of central venous catheter, we measured the distance from the skin puncture site to subclavian vein-right atrial junction using transesophageal echocardiography. RESULTS: The measured distance highly correlated with the patient height. Based on these data, following guideline could avoid intra-atrial placement in 94% of the time: optimal depth of insertion (cm) = 2.5 + (0.06 x height). CONCLUSIONS: We postulate that initial using a simple practical guideline could prevent malposition of central venous catheter.

BACKGROUND: The characteristic of pediatric cardiopulmonary resuscitation (CPR) is different from that of adult CPR. It is known that respiratory arrest is more common in pediatric CPR compared to adults. The objective of this study was to report the characteristics of in-hospital CPR according to four pediatric Utstein groups. METHODS: We reviewed all medical records that were coded as CPR, care for arrest, defibrillation/ cardioversion, and ambu in our children's hospital. We classified the patients in 4 groups, isolated respiratory compromise, pure respiratory arrest, respiratory arrest leading to cardiac arrest and cardiac arrest. The data were summarized and analyzed in pediatric Utstein style. RESULTS: In 2001, 138 patients aged less than 15 years were resuscitated in our children's hospital. The success rate after resuscitation was 100% in the isolated respiratory compromise group, and 100% in the pure respiratory arrest, 54% in the respiratory arrest leading to the cardiac arrest group, and 24.8% in the cardiac arrest group. CONCLUSIONS: We conclude that the isolated respiratory compromise group and the pure respiratory arrest have better results than the respiratory arrest leading to the cardiac arrest group and the cardiac arrest group, considering all characteristics.

BACKGROUND: One nostril must be selected for nasotracheal intubation. In some cases, structural anomalies within the nasal cavity hinder the insertion of the tube or complications, such as epistaxis, develop. This study examined the possibility of using radiography to select the nostril that would induce fewer complications. METHODS: Four hundred and five patients who underwent nasotracheal intubation under general anesthesia were studied. A 7.0-mm internal diameter nasal right angle endotracheal (RAE) tube and 6.5-mm internal diameter nasal RAE tube were inserted into men and women, respectively. Complications were considered to have developed in cases in which insertion of the tube into the nasal cavity failed or epistaxis occurred. The tube was inserted into the other nostril for insertion failures and hemostasis was performed in cases of epistaxis. The degree of nasal septal deviation was determined from posteroanterior skull radiographs or panoramic radiographs; the incidence of complications was compared depending on the direction of the septal deviation and the intubated nostril. RESULTS: The radiographs of 390 patients were readable; 94 had nasal septum deviation. The incidence of complications for cases without nasal septum deviation was 16.9%, that for cases in which the tube was inserted into the nostril on the opposite side of the deviation was 18.5%, and that for cases in which the tube was inserted into the nostril with the deviation was 35.0%, showing a high incidence of complications when intubation is performed through the nostril with septum deviation (chi-square test, P < 0.05 ). CONCLUSIONS: Although there were no differences in the incidence rates of complications between intubation through the left nostril and that through the right nostril, radiological findings indicated that incidence of complications significantly increased when the tube was inserted into the nostril with the septum deviation.

PURPOSE: Mentally disabled patients show different recovery profiles compared to normal patients after general anesthesia. However, the relationship of dose-recovery profiles of mentally disabled patients has never been compared to that of normal patients. MATERIALS AND METHODS: Twenty patients (10 mentally disabled patients and 10 mentally intact patients) scheduled to dental surgery under general anesthesia was recruited. Sevoflurane was administered to maintain anesthesia during dental treatment. At the end of the surgery, sevoflurane was discontinued. End-tidal sevoflurane and recovery of consciousness (ROC) were recorded after sevoflurane discontinuation. The pharmacodynamic relation between the probability of ROC and end-tidal sevoflurane concentration was analyzed using NONMEM software (version VII). RESULTS: End-tidal sevoflurane concentration associated with 50% probability of ROC (C50) and gamma value were lower in the mentally disabled patients (C50=0.37 vol %, gamma=16.5 in mentally intact patients, C50=0.19 vol %, gamma=4.58 in mentally disabled patients). Mentality was a significant covariate of C50 for ROC and gamma value to pharmacodynamic model. CONCLUSION: A sigmoid Emanx model explains the pharmacodynamic relationship between end-tidal sevoflurane concentration and ROC. Mentally disabled patients may recover slower from anesthesia at lower sevoflurane concentration at ROC an compared to normal patients.
