Nausea and vomiting are common problems after strabismus surgery in pediatric patients. We compared the effect of propofol with N2O with the effect of a conventional regimen consisting of halothane - N2O on the occurrence of oculocardiac reflex(OCR), recovery characteristics and the incidence of postoperative emesis after strabismus surgery in 46 ASA physical status I children. After intravenous injection of atropine(0.02 mg/kg), patients were randomly assigned to one of two groups. Group l(conrol) received thiopental, vecuronium, halothane and N2O; Group 2(study), propofol 2 mg/kg and vecuronium bolus followed by infusion of propofol 160 mg/kg/min. Patients in group 2 had more episodes of OCR response than group 1, but had shorter time to recovery from anesthesia(p<0;05). But there was no significant difference in the incidence of postoperative nausea and vomiting between two groups. We conclude that the sufficient doses of propofol only regimen and atropine preadministration(0.02 mg/kg) will be necessary in the strabismus surgery of children for the purposes of the prevention of intraoperative OCR, rapid recovery from anesthesia and reduction of postoperative emesis.

Airway obstruction following endotracheal intubation may be fraught with danger. Foreign bodies often become lodged in the airway as a result of trauma or rupture of lung lession. Somtiems they are revealed at the time of respiratory obstruction. Injury to individual mass lession is not seen so often. We experienced two cases of airway obstruction due to dislodging of foreign bodies. By exchanging obstructed endotracheal tube or removal of extracted teeth with aid of bronchoscope, the patency of the airway could secured. The aim of this case report is to emphasize that the insertion of an endotrahceal tube does not completely guarantee the patency of the airway.

Massive blood transfusion may be defined as the acute administration of blood more than one and a half times the patient's estimated blood volume. When stored whole blood is infused, complications such as coagulation defect, volume overload, acid base disturbance and pulmonary complications will develop. Massive transfusion has been associated with the development of adult respiratory distress syndrome(ARDS) in man, and both humoral factor and microemboli have been proposed as the injurious agent in the transfused blood. WE experiecned the patient who had suffered from acute respiratory failure after the transfusion of massive amount of whole blood and managed him effectively with ventilatory support with positive end expiratory pressure under the monitoring of cardiopulmonary function via the Swan-Ganz Catheter at ICU.

Excessive peak airway pressure during general endotracheal anesthesia may result from bronchospasm due to light anesthesia or surgical stimulation, bronchial intubation, tension pneumothorax, pulmonary edema, or mechanical obstruction of tube, whether from kinking, inspissated secretions, or overinflation of the cuff. Usually these problems are differentiated with auscultation and drug administration. However, mechanical problems associated with the endotracheal tube may be a cause of increased airway pressure. Reinforced, anode, or armored tubes consist of two coatings of latex or PVC that enclose spiral metal windings. Because of that, the inner layer may peel away, and intraluminally bulge due to nitrous oxide and cause airway obstruction during the course of an anesthetic process. We report a case of intraluminal bulging of the inner layer in a reinforced tube using fiberoptic bronchoscopy during anesthesia.

BACKGROUND: Intraoperative oculocardiac reflex (OCR) and postoperative nausea and vomiting (PONV) are common problems of pediatric strabismus surgery. Propofol is thought to increase the incidence of OCR in spite of profound antiemetic effect. The goal of this study was to assess, in pediatric strabismus surgery, the incidence of OCR and PONV in a propofol with and without nitrous oxide (N2O) anesthesia. METHODS: Children (1~14 yr.'s) undergoing strabismus surgery as in patients were randomly allocated to two anesthetic techniques: propofol with 60% N2O and propofol with air instead of N2O. All children received iv fentanyl 2 microgram/kg, atropine 0.015 mg/kg and 1% lidocaine 1.5~2 ml before propofol 2.5 mg/kg injection. Anesthesia was maintained with three stage infusion method of propofol with and without N2O by groups after intubation with atracurium 0.4 mg/kg. A significant OCR was defined as an acute decrease in heart rate of 20% or greater associated with traction on an ocular muscle. RESULTS: Data on 224 children were analyzed. An intraoperative OCR was elicited in 41 (36.9%) of the 111 children in the N2O group and in 66 (58.4%) of the 113 children in Air group, while 14 (12.6%) and 12 (10.6%) developed PONV in the N2O group and the Air group in the subsequent 24 hr. period. The OCR was more frequent during medial rectus muscle correction (62.5%) than in lateral rectus muscle correction (39.5%). There was no significant correlation between OCR and PONV. CONCLUSIONS: We conclude that propofol with N2O anesthesia was effective in reducing the incidence of intraoperative OCR with a similarly excellent postoperative antiemetic effect in pediatric strabismus surgery compared to propofol without N2O anesthesia.

Introduction: Anesthesiologists have been aware of the dangers of diffusion hypoxia in the early postoperative period after nitrous oxide anesthesia, but it was suggested of a little clinical significance in healthy patients. Goal of this study is to re-evaluate the possibility of diffusion hypoxia. METHODS: Eighty patients who were scheduled for vitrectomy were allocated to two groups by normal and abnormal chest X-ray findings and each group was divided into two subgroups by N2O concentration (1-a, 2-a; 50%, 1-b, 2-b; 60%). One and half hours after anesthesia, end-tidal alveolar concentration of oxygen (et-O2), N2O (et-N2O), and PaO2 were measured for 10 minutes after the inspired gases were changed to room air 2 L/minute with controlled ventilation in group 1-a. Those parameters were re-measured after re-administration of O2 and N2O of 50% of each for an hour and the inpired gases were changed to room air again. RESULTS: In group 1-a, there was no significant differences of et-N2O and PaO2 after 5 minutes by air flow. And there was no differences of et-N2O and PaO2 between group 1-a and 1-b by et-N2O after 4 minutes. In group 1-b, PaO2 was in normal range at 10 minutes after, although et-O2 was decreased to 14.9%. However, group 2-b showed peripheral arterial saturation lower than 96% after 6 minutes and mild hypoxemia (PaO2 75.3 mmHg) at 10 minutes. CONCLUSIONS: We suggest that hypoxemic episode during spontaneous breathing of room air in early postoperative period after nitrous oxide anesthesia may be occur due to decreased ventilatory function rather than diffusion of nitrous oxide. However, in patients with minimal abnormal chest X-ray findings even without clinical symptoms, it would be better to avoid high concentration of nitrous oxide.

THE NECESSITY AND PURPOSE OF THE STUDY: Recently the number of patients with chronic diseases and the aged patients is increasing steadily. Furthermore, due to the expansion of health insurance system, the number of patients hospitalized in the general hospital is increasing at a surprising speed. However, hospitals urge the early discharge of the patients for the efficiencies of hospital administration, and therefore, the number of patients who must be taken care of in their home is also increasing. Homecare nursing is one of the health care service for the patients at home who require continual attention and care, and now increasing attentions are given to it as one of the professional nursing fields. However, it was almost impossible to find a study on the actual experiences of the homecare nurses written by their own language in Korea, that it also posed a great difficulty in understanding their diverse experience. Considering these situation, this study will help understanding of them, and provide the fundamental data on their experiences for making policies to develop homecare nursing. METHODS OF RESEARCH: Phenomenological research method was employed to analyze the lived experiences of homecare nurses fundamentally. DATA COLLECTION: Data were collected from August 1998 to December 1998 from ten homecare nurses who worked for patients under the homecare nursing setting as model cases designated by Seoul Nurses Association and who agreed to the purpose of this study after listening to and understanding the explanation completely. The in-depth interview was carried at the time which was convenient both for the researcher and participants for one or two hours, and recovered with the approval participants. The first interview covered diverse and broad areas like the situation of homecare nursing, and their feelings and thoughts over it, and in the second and third interviews, more specific questions are asked. DATA ANALYSIS: For the phenomenological analysis, contents analysis was employed. The data collected from the participants were analyzed into the following procedures according to Van Manen 's phenomenological analysis. 1) Reserve the preconception of the researcher by restricting it inside parenthesis. 2) Make a thorough observation of the lived experiences by insight process. 3) Analyze the contents (Find out the repetitive factors) 4) Interpret the essence found. 5) State the meaning of the interpretation. RESULTS AND DISCUSSION: 1. Fear and expectation for the first visit. (unfamiliarity, awkwardness, anxiety, shivering) 2. Mingle with the family (feeling friendly with the family, becoming like a family member) 3. Being proud of her own know-how (learning the know-how, organizing alternatives, building up confidence) 4. Pity for the poor. (criticizing the current government, feeling ashamed, feeling anger) 5. Difficulty of constructing cooperative system with physicians (strenuousness, frustration) 6. Helplessness due to the lack of support system (difficulty to get supplies, annoyance, embarrassment by institutional restraints) 7. Anxiousness for heavy traffic and parking (annoyance, hastiness) 8. Ethical conflicts (pity for the patients and family, skepticism about lengthening life maintenance) 9. Burden for the possible accident (pressure, anxiety, conflict, physical exhaustion) 10. Establishment of identity as a professional (fulfillment, worth, joy) 11. Being distressed at other's ignorance

Although single-shot caudal blockade is known as a relatively safe procedure, it is not always without complications. We present a case of accidental bladder puncture that was identified with fluoroscopy by chance after single-shot caudal blockade in a 17-months-old, 12 kg boy who underwent inguinal hernioplasty.
