Objective: The purpose of this study was to identify the effects of tracheal suction and the effects of different methods of bronchodilator inhalation (Ultrasonic nebulizer: MDI puff, MDI puff with spacer) in VSD surgery patients. Material & Method: From June 2001 to March 2002, sixty consecutive patients were randomly assigned to a control group (n= 15), ultrasonic nebulizer group (n=15), metered dose inhalation (MDI) puff group (n=15) and MDI with spacer group (n=15). Vital signs (HR, BP, CVP), ABGA and pulmonary functions were measured before suction (baseline for suction), after suction, 15 minutes after suction (base of bronchodilator inhalation), 30 minutes after bronchodilator inhalation, and 2 hours after bronchodilator inhalation. Stastistical analysis was performed using SPSS software. Repeated measure ANOVA was used to examine the effects of tracheal suction. One way ANOVA with Bonferroni's correction and multiple range test (the least significant difference test) were used to examine the effects of albuterol inhalation. Result: 1. Heart .ate increased significantly immediately after suction (p<.01) and recovered 15 minutes after suction. 2. $PaO_2$ and PH decreased significantly immediately after suction (p<.05) and $PaO_2$ recovered 15 minutes after suction. $PaCO_2$ increased immediately after suction and significantly 15 minutes after suction (p<.01). But changes in vital signs and ABGA were within the normal range. 3. Tidal volume decreased significantly 15 minutes after suction (p<.05). 4. Changes of HR and tidal volume were greater in the nebuizer group compared to the other groups (p<.05) 30 minutes after bronchodilator inhalation and recovered 2 hours after bronchodilator inhalation. 5. Changes of airway deadspace was greater in the nebulizer group compared to the control group and MDI puff group 30 minutes after albuterol inhalation (p<.05) and at 2 hours (p<.01). Conclusion: Tracheal suction did not have significant effect on vital signs and pulmonary functions after OHS. Although the methods of bronchodilator inhalation did not showed any significant difference on pulmonary function, the nebulizer method increased $PaO_2$ (20%) and tidal volume transiently. If the patient needs bronchodilator inhalation with bronchospasm after OHS, the nebulizer method is the best choice. More study on the effects of bronchodilator inhalation in bronchospasm group is needed.

The present study was performed to elucidate the effect of canine electroacupuncture anesthesia on vital signs and blood gas values. Groups were divided into experimental (electroacupuncture: EA) and control (ketamine) groups. The vital signs (body temperature, respiration rate and pulse) and blood gas values (pH, $pCO_2$ and $pO_2$) of venous and arterial blood were determined. Body temperatures of EA group were significant higher than than of ketamine group at 15 min., 30 min., 45min. and 60 min. (p<0.05) after anesthesia, respectively. The respiration rates of EA group were higher than those of ketamine group, however, significant differences were not observed between both groups. The pulses of EA group were significant higher than those of ketamine group at 5 min. (p<0.05), 10 min. (p<0.01), 15 min. and 30 min. (p<0.05) after anesthesia, respectively. The arterial and venous blood pHs of ketamine group were slightly higher than those of EA group, respectively, however, no significant differences were found between both groups. Significant differences were not observed between both groups in the arterial and venous blood $pCO_2$, respectively. The arterial blood $pO_2$ of EA group was significant higher than those of ketamine group at 5 min. (p<0.05) after anesthesia. No significant differences were observed between both groups in the venous blood $pO_2$. These results suggest that the changes of vital signs and blood gas values of EA group are similar to those of ketamine group with the exception of changes in the body temperature, pulse and arterial blood $pO_2$.

Objectives This study is designed to evaluated the safety of peony root extract tablet in healthy male volunteers. Methods 12 healthy male volunteers were recruited, and this study was conducted by a single center. The safety was evaluated by collecting laboratory test and vital signs of volunteers. As the registration process, 12 subjects were assigned by serial number. To evaluate safety, vital signs were checked and blood samples were collected 4 times during the screening period, pre & post-administration (after 8 hours) and post-administration (after 7 days). The difference in variables was summarized by the mean±standard deviation. The normality test was carried out using the Shapiro-Wilk test and Kolmogorov-Smirnov test. When normality is fulfilled, a paired t-test is applied and the significance level was p<0.05. And the incidence of all adverse effects and serious adverse effects are shown in percentage. Results In the case of vital sign, body temperature (BT) (℃) was 0.06±0.05 ℃ (p=0.008), and there was a statistically significant difference in before and after administration. However, clinical symptoms were not occurred and BT (℃) of all subjects before and after administration showed values within the normal reference value. There was no significant difference from the control group in all other vital signs and laboratory test data. And no side-effects associated to clinical trial drugs were followed. Conclusions The peony root extract tablet was considered to be safe for healthy male volunteers.

The recent advances in wireless communication systems and semiconductor technologies are paving the way for new applications over wireless sensor networks. Health-monitoring application (HMA) is one such emerging technology that is focused on sensing and reporting human vital signs through the communication network comprising sensor devices in the vicinity of the human body. The sensed vital signs can be divided into two categories based on the importance and the frequency of occurrence: occasional emergency signs and regular normal signs. The occasional emergency signs are critical, so they have to be delivered by the specified deadlines, whereas the regular normal signs are non-critical and are only required to be delivered with best effort. Handling the occasional emergency sign is one of the most important attributes in HMA because a human life may depend on correct handling of the situation. That is why the underlying network protocol suite for HMA should ensure that the emergency signs will be reported in a timely manner. However, HMA based on IEEE 802.15.4 might not be able to do so owing to the lack of an appropriate emergency-handling mechanism. Hence, in this paper, we propose a new emergency-handling mechanism to reduce the emergency reporting delay in IEEE 802.15.4 through the modified superframe structure. A fraction of an inactive period is modified into three new periods called the emergency reporting period, emergency beacon period, and emergency transmission period, which are used opportunistically only for immediate emergency reporting and reliable data transmission. Extensive simulation is performed to evaluate the performance of the proposed scheme. The results reveal that the proposed scheme achieves improved latency and higher emergency packets delivery ratio compared with the conventional IEEE 802.15.4 MAC.

Objectives The purpose of this study is to understand what caregivers think advantageous and disadvantageous regarding Acupoint sticking Dog-days. Also, to know whether Acupoint sticking in Dog-days affect vital signs, and to investigate if occurrence of side effects are related to application duration, sweat, or compliance to precautionary measures. Methods Survey has been handed out to parents of the children who took Acupoint sticking in Dog-days. 10 days after the first dose was administered, survey was performed to examine any side effect occurrences, characteristics of sweat, duration of application, parents' thought about this therapy. Also, vital signs were checked before the first dose, and 10 days after to see any differences in vital signs in regards to this therapy. Results Preferable opinions about Acupoint sticking in Dog-days are 'convenient than herbal medications' (76.5%), 'less reluctance of child' (47.1%), 'reasonable price' (20.6%), 'good effectiveness' (17.6%), 'less side effect' (14.7%), 'no worry about agrochemicals or heavy metals uptake' (11.8%). Downsides were 'difficult to admit to hospital right on the Dog-days' (73.5%), 'no conspicuous effectiveness' (11.8%), 'expensive' (5.9%), 'reluctance of child' (2.9%). Vital sign differences were minimal when examined before and after Acupoint sticking in Dog-days. Side effects occurred 5 times in 34 cases, and they were erythema, itchiness, and hot sensation. There were no scars or blisters reported. All 5 cases were resolved without any interventions within 3 days. Conclusions Acupoint sticking in Dog-days doesn't affect vital signs. Severe side effect is rare, reported side effects were relatively mild, suggesting that it may be safe and well-tolerated. 'Convenience' (76.5%) is biggest advantage of Acupoint sticking in Dog-days and 'less reluctance of child' is also big advantage of Acupoint sticking in Dog-days. 'Difficulty to admit to hospital right on the Dog-days' (73.5%) is biggest disadvantage of Acupoint sticking in Dog-days.

There are many possible causes of duodenal obstruction, such as congenital anomalies and various acquired conditions associated with space-occupying lesions. However, hemorrhage or retroperitoneal hematoma is a rare cause of duodenal obstruction. Here, we report the case of a 55-year-old man who developed duodenal obstruction due to a large retroperitoneal hematoma after acupuncture therapy. The patient experienced abdominal discomfort along with vomiting and nausea. Considering the size of the hematoma, emergency surgery could have been performed, but conservative treatment was continued because the patient's vital signs were stable. With spontaneous resolution of the hematoma, the symptoms of duodenal obstruction improved. The patient was eventually discharged without any complications associated with the hematoma. Our findings suggest that even when a hematoma is large, a conservative approach can be maintained until improvement of the symptoms of duodenal obstruction if the vital signs of the patient remain stable.

Gastric artery bleeding after blunt trauma is rare. In such cases, if vital signs are stable, angiographic embolization may be performed. Although gastric artery embolization is known to be safe due to its anatomical properties, complications may occur. We report a case of gastric necrosis after gastric artery embolization in a patient with blunt abdominal trauma. The 55-year-old male patient was found with gastric arterial bleeding after a traffic accident. His vital signs were stable, and gastric artery embolization was performed. Gastric necrosis was subsequently found, which was treated surgically.

The purpose of this study is to clarify that neonatal massage is a nursing intervention which is desirable to LBW by making nurses provide such massage service to LBW hospitalized at NICU and confirming effects of the service on weight gain, vital signs and stress hormones(cortisol, norepinephrine, epinephrine). The data were collected from Dec. 14, 1998 to Oct. 4, 1999. The subjects were 28 LBW infants. The data were analyzed with the SAS program with T-test, Chi-square test and ANOVA. 1. The Experimental group that received neonatal massage showed a higher daily gain of weight than the comparative group. Weight gain for 10 days and weight gain of seven days after the massage were also higher in the former group than in the latter, indicating that there are statistically significant differences between the two groups.
