This study is a nonequivalent control group pre- and post-test design research whose purpose was to determine what effects the pre-operation provision of information has on the anxiety and uncertainty of mothers with a pre-school child of tonsillectomy and nursing satisfaction after the operation. Data were collected from mothers whose child underwent tonsillectomy at S general hospital. For the collection, those mothers were divided into the experimental and control groups, respectively consisting of 19 and 20 members. The experimental group was provided general education about the operation. In addition, they individually received information about the procedure that the researcher and an assistant provided on one-to-one basis for about 20 minutes, in which brochures containing the information were used. While, the control group was provided only general education as mentioned above. For data analysis, this study conducted ${\chi}^2$-test, Fisher's exact test and Mann-Whitney U-test. The pre-operation provision of information was found having brought significant differences between the control and experimental groups in their anxiety(U=104.5, p=.015) and uncertainty(U=83.5, p=.002) as well as their satisfaction after the operation(U=109.5, p=.022). The findings of this study strongly suggest that information provision before the operation is positively effective in reducing the anxiety and uncertainty of mothers with a tonsillectomy child and increasing their nursing satisfaction after the operation. These effects need to be more verified through repetitive and subsequent researches and by using many other methods of information provision.

This study was to identify the effects of supportive nursing intervention using video-program of operating room nurses before operation on laparoscopic hysterectomy patient's anxiety. This study was nonequivalent control group pre-post test design. The data were collected from May 1 to Jun 20, 2013 and analyzed by $x^2-test$, Fisher's exact test and t-test using SPSS 20.0 program. Experimental group(who received supportive nursing intervention) and control group(who received booklet education) was respectively consisted of 25 patients who were laparoscopy hysterectomy. The anxiety(p=.002) of experimental group was significantly lower than control group. The systolic(p=.012) and diastolic(p=.045) pressure of experimental group was significantly lower than control group, but pulse wasn't. The supportive nursing intervention for preoperative patient is considered effective and useful in reducing anxiety. Further research is warranted to investigate the supportive nursing intervention long-term effect.

Since thoracoscopy was originally described by Jacobaeus in 1922, video-assisted thoracic surgery has been used to treat many thoracic diseases. From June 1994 to July 1995, 35 patients with spontaneous pneumothorax'underwent video-assisted thoracic sugery as experimental group, and same number of patien:s with blob resection through mid-axillary thoracotomy as co trol group in our hospital.'The authors compared the clinical results between each group. 1. The sex distributions were 28 males, 7 females in experimental group and 30 males, 5 females in control group. The mean age of experimental group was 28.5 $\pm$ 12.6 years of age and that of control group was 2).9 $\pm$ 6.3 years of age. 2. The operative times were 98.8$\pm$ )9.3 minutes in experimental group and 103.6$\pm$ )2.6 minutes in control group. ). The duration of chest tube indwelling at postoperative period was 2.60 $\pm$ 0.98 days in experimental group, 4.80 $\pm$ 2.08 days in control group (P< 0.01). The periods of postoperative hospitalization were 17 $\pm$ 1.22 days in experimental group and 6.69 $\pm$2.52 days in control group. The durations of post-oper- ative chest tube indwelling and hospital stay in experimental group were shorter than in control group (P< 0.01 respectively). 4. The injection of analgesics at postoperative period was less in experimental group than control group. At the operative day and postoperative 1 st and 2nd day, the number of injections were respectively 1. 57$\pm$0.74, 1.97 $\pm$0.70 and 1.00$\pm$0.68 times/person in experimental group, 2.23 $\pm$0.60, 2.60 $\pm$0.67 and 2. 17$\pm$0.76 times/person in control group(P<0.01 respectively). The mean duration and dose of postoperative analgesic injection were 2.48$\pm$ 1.01 days/person and 4.88 $\pm$3.70 ampules/person in experimetal group, 3.70$\pm$ 1.40 days/person and 8.94 $\pm$4.21 ampules/person respectively (P< 0.01, p<0. 01).

레이저를 이용한 구강 및 인후두 수술시 endotracheal tubes의 손상은 치명적이라 아니 할 수 없다. 이에 저자들은 여러 가지 endotracheal tube를 실험 재료로 사용하여 보다 안전한 레이저 수술을 위해서 적절한 endotracheal tube를 찾기 위해 본 실험을 시행하였다. 실험에 사용된 tube는 총 5가지 - $Bivona^{TM}$, Xomed Laser Shield $II^{TM}$, Mallinckrodt Laser-$Flex^{TM}$, Rusch tube wrapped with aluminium foil tape(Rusch tube), Polyvinylchloride tube wrapped with aluminium foil tape(PVC tube) - 가 사용되었다. 사용된 레이저는 KTP/532 와 $CO_2$ laser 이며 모든 실험에서 tube를 $FiO_2$ 95%-98% 상태에서 조사하여 각각 5회씩 실시하였다. tube에 이상이 없거나 발화가 되지 않는 한 90초 동안 시행하였다. 실험 결과, KTP/532 조사시 $Bivona^{TM}$, Mallinckrodt 와 PVC tube는 심한 손상을 받거나 발화하였으며 Xomed 와 Rusch tube는 안정된 상태를 유지하였고 $CO_2$ Laser 조사시는 KTP/532 조사시와 유사한 결과를 얻었다. 한편 혈액을 endotracheal tube에 도포한 상황에서는 모든 tube가 더 심한 손상을 보이는 바 KTP/532 조사시 Xomed는 상당히 안정된 상태를 유지하였고 나머지 tube는 심한 손상 또는 발화를 보이고 $CO_2$ Laser 조사시 $Bivona^{TM}$ 와 Mallinckrodt는 발화하였고 Rusch tube는 표면이 녹았으며 Xomed와 PVC tube도 1례에서 발화하였다. 향후 이비인후과 영역에서의 레이저 수술이 증가함을 예상할 때 좀 더 레이저에 대하여 안정적이고 경제적인 endotracheal tube의 개발이 필요할 것으로 사료된다.

This study's purpose is to determine the effects of aroma inhalation on preoperative pain and anxiety of the elderly preparing to undergo a spine surgery. A Quasi-experimental design, with non-equivalent control group non-synchronized design was used in this study. Blended essential oils with frankincense, marjoram and mandarin were inhaled twice in the experimental group (n=30). The control group (n=30) was treated with the standard preoperative care. Pain, state anxiety, and vital sign were measured twice (before and after). The results of this study showed that pain (t=-1.223, p=.226), systolic blood pressure (t=-0.211, p=.833), diastolic blood pressure (t=0.638, p=.526), and respiration rate (t=0.734, p=.466) were not statistically significant in the experimental and the control group. There were significant differences in state anxiety (t=-3.202, p=.002) and pulse rate (t=-0.213, p=.037) in the experimental group compared to the control group. According to the results, aroma inhalation is an effective nursing intervention for relieving anxiety in surgical patients.

This study used a nonequivalent control group pretest-posttest design to develop an information provision program for arteriovenous fistula and angioplasty patients and to examine the effects of the information provision program offered by operating room nurses. The research subjects were selected trough convenience sampling who had come to hospitals to have an arteriovenous fistula and angioplasty surgery, and an experimental group and a control group of 40 persons. The information provision program consisted of two sessions, each conducted on the day of surgery and after surgery. The content included surgery information, pain management after surgery, management of dialysis blood vessels, how to handle emergency, and management of complications. The results of the study showed that the experimental group, which was offered an information provision program by nurses, a decrease in trait and state anxiety and an increase in self-efficacy on a statistically significant level. In conclusion, the information provision program provided by operating room nurses helped to reduce anxiety in arteriovenous fistula and angioplasty patients and increase their self-efficacy. This will improve end-stage renal disease patients' self-management ability after surgery, and thus, contribute to improving the prevention of complications and the level of self-nursing care.

The purpose of this study was to examine the effect of deep breathing exercise with Incentive Spirometer on the pulmonary ventilatory function of postoperative patients. This experiment was operated by quasi-experimental design which was compared pre-experimental measures with post-experimental ones. The subject of this study was 46 inpatients who were scheduled for elective upper abdominal surgery under the general anesthesia in P National University Hospital in Pusan and classified into the experimental group(23 patients) and control group(23 patients) by using Incentive Spirometer or unusing one. The data were collected from November, 1, 1993, to December, 31, 1993. The effects of the deep breathing exercise on the pulmonary ventilatory function were compared between experimental group who were recieved deep breathing exercise with Incentive Spirometer and control group who were recieved same method without Incentive Spirometer. The Forced Vital Capacity (FVC) and the First Second Forced Expiratory Volume ($FEV_1$) were represented as index of the pulmonary ventilatory function and those were measured by Vitalograph Compact. The collected data were analysed by SPSS/PC+ (percentage, average, standard deviation, chi-square test, t-test, and ANOVA). The results were as follow : (1) The $FVC_s$ of the experimental group were significantly increased in course of time, 24, 48, 72 hours after surgery(F=3.530, P=0.035). (2) The $FVC_s$ and $FEV_{1S}$ of the control group were significantly increased in course of time, 24, 48, 72 hours after surgery ($FVC_s$ : F=3.480, P=0.037, $FEV_{1S}$ : F=6. 153, P=0.004). (3) The FVC which was measured at 72 hours after surgery was significantly higher in the experimental group than in the control group(t=2.620, P=0.013). (4) The $FEV_{1s}$ which were measured at 24 and 72 hours after surgery were significantly higher in the experimental group than in the control group(24hr. : t=2.530, P=0.017, 72hr. : t=2.540, P=0.016). (5) Among general characteristics, sex was significant variable which influenced to effect of pulmonary ventilatory function. In conclusion, this study showed that the deep breathing exercise with Incentive Spirometer was more effective to recover the pulmonary ventilatory function after surgery than the deep breathing exercise without Incentive Spirometer.

Experimental trials of unilateral lung transplantation in dogs have been attempted and satisfactory results were obtained without any noticeable difficulty in surgical techniques. Fourteen dogs with the body weight of around 25 kg were anesthesized by 20~30 mg/kg of intravenous Entobar,; one was sacrificed to make available blood for use during transplantation for the recipient dog. A mid-sternotomy incision was performed and 20 mg/kg of Prostaglandin E1 was infused through the pulmonary artery and Euro-Collin's(E-C) preservation solution, cooled down to 4$^{\circ}C$, was perfused at the rate of 70cc/kg by a pressure of 30 cmH2O. The heart-lung block was then resected out and promptly immersed in the prepared preservation solution at 4$^{\circ}C$. One lung preserved in the EC solution at 4$^{\circ}C$ was anastomosed to the recipient dog in the order of the pulmonary vein, bronchus then pulmomary artery and the thoracotomy incision was closed after the bleeding control and tube thoracostomy. Then the pneumonectomy in the opposite side was perfomed in the same manner and the tailored lung was transplanted in the order of the pulmonary vein, bronchus, then pulmonary artery. We conclude that in the bilateral sequential lung transplantation, the right lung transplantation should precede to better expose the operative field and to prevent reperfusion injury; also, the cardiopulmonary bypass should be consider for certain appropriate cases.
