Airway obstruction in pediatric patients always poses a challenge for anesthesiologists. Beckwith-Wiedemann syndrome causes various abnormalities such as macroglossia and omphalocele. Patients with these abnormalities often need corrective surgeries. Management of difficult airway caused by conditions such as macroglossia in patients with this syndrome could be challenging. We encountered a case of difficult airway in an infant with Beckwith-Wiedemann syndrome. It was predicted that macroglossia might cause difficult ventilation, intubation, and extubation. Preoperative assessment and preparations for difficult airway should be considered.

Purpose: To identify the perception and practices of kangaroo care in nurses and doctors working in neonatal intensive care units (NICU) in Korea. Methods: One hundred forty-nine nurses and nineteen doctors working in the NICU from six university hospitals completed a survey questionnaire. Results: Most agreed that Kangaroo care promoted attachment and parental confidence as well as physical health of the infant. However, nurses and doctors showed a negative perception in providing kangaroo care for premature infants under 1,000 grams or within several hours after birth. Major barriers for kangaroo care were worrying about extubation and safety problems of premature infants. Married or senior nurses showed a more positive perception than others. Also nurses who worked in hospitals where kangaroo care was provided had a lower barrier perception than other nurses. Conclusion: Nurses and doctors working in NICU worried about adverse effects of kangaroo care even though they perceived positive effects. Standard education programs and manuals should be developed before dissemination of kangaroo care in Korea.

Rett syndrome (RS) is a neurodevelopmental disorder characterized by loss of cognitive, motor, and social skills, epilepsy, autistic behavior, abnormal airway patterns, gastroesophageal reflux, nutritional problems, and severe scoliosis. Although girls with RS show normal or near-normal growth until 6-8 months, they lose their skills after that. The anesthetic management of these patients requires care because of all these clinical features. Especially in the postoperative period, prolonged apnea is common and extubation is delayed. In this case report, the effect of using sugammadex was presented in a 16-year-old girl with RS. The patient's all bimaxillary teeth and 4 wisdom teeth were extracted under general anesthesia in one session with minimal surgical trauma and moderate bleeding. Sugammadex can be a rapid and reliable agent for the reversal of the neuromuscular block in neurodegenerative patients.

Agenesis of the hemidiaphragm is unusual congenital anomaly associated with a high mortality. A case of congenital agenesis of left diaphragm was experienced in 22-day old male patient who was dyspneic and cyanotic on admission. Emergency exploration through the left eight interspace thoracotomy showed complete agenesis of the left diaphragm. The stomach and transverse colon covered with peritoneal sac was partially herniated into left hemithorax. The left lung was slightly hypoplastic. This neonate had no intestinal malrotation. The defect was reconstructed using Dacron graft. Dacron patch was sutured with interrupted Ethibond to chest wall anteriorly, esophagus aorta and costomediastinal sinus medially, and the tenth rib posterolaterally. Postoperatively, Extubation was performed at 1st day, but some respiratory difficulty was noted. Severe dyspnea was occurred at postoperative 11th day and so reintubation was done. Intermittently ventilatory support and intravenous alimentation were continued for 9 days after that. Thereafter he had no respiratory problems at discharge.

Increasing success in the management of patients with severe respiratory failure by mechanical respirators has produced iatrogenic tracheal stenosis. And the surgical management of these lesions have provided a major field for tracheal reconstructive surgery. Recently we have experienced three cases of postintubation tracheal stenosis between December, 1985 and October, 1987 and successfully performed circumferential resection and end to end anastomosis of the trachea. The lesion of the first case which was located in the subcricoid level was resected about 2cm length with cervical incision. And the lesion of the second case located at the cuff site was also resected about 2.5cm length with cervical and median sternotomy incision. Also the lesion of the third case located at the stoma site was resected about 1.8cm length with cervical incision. The postoperative courses were uneventful but there was extubation difficulty in the third case because of stupor mentality and problem of secretion excretion. So we have observed the postoperative course after T-tube insertion.

We have experienced 2 cases vocal cord paralysis after open heart surgery. One was a postoperatively developed right unilateral vocal cord paralysis after prosthetic mitral valve replacement with tricuspid valve annuloplasty. The other was a postoperative left unilateral vocal cord paralysis after prosthetic aortic and mitral valve replacement with tricuspid annuloplasty. They were intubated for forty-eight and seventy-two hours but after extubation complained of hoarseness, aphonia, anxiety, and ineffective coughing Indirect laryngoscopy performed at about postoperative one week, revealed partial paralysis and decreased mobility of the vocal cord. After active phonation therapy, symptoms were improved gradually and in the follow up indirect laryngoscopy, the vocal cord paralysis was improved. The symptoms were recovered completely at about postoperative one month in both. The cause of vocal cord paralysis after open heart surgery may be any retraction or stretching injury to the recurrent laryngeal nerve, especially right side, during median sternotomy retraction and open heart operation procedures. As a result, avoid of excessive spread of median sternotomy retractor and excessive manipulation and retraction of the heart during open heart procedures will reduce the occurrence of the vocal cord paralysis.

Penetrating chest trauma by stab injury may result in massive hemothorax from damage to single or multiple intrathoracic organs such as heart, aorta, internal mammary artery, intercostal artery or pulmonary parenchyme. Prognosis of massive hemothorax necessitating emergency thoracotomy is fatal especially so if there exists concomitant underlying compromise of cardiopulmonary function. A 56 year old man with destroyed left lung due to old pulmonary tuberculosis was stabbed in right parasternal lesion through third intercostal space. Intubation with cardiopulmonary resuscitation and closed thoracostomy were performed to resuscitate from cardiac asystole from hemorrhagic shock and acute respiratory distress. Midsternotomy was made to expose active bleeding foci in right mammary artery, subclavian vein, intercostal artery and anterior segment of right upper lung showing severe bullous change and pleural adhesion. Postoperative care included ventilator support, inotropic instillation and cautious, balance fluid therapy ; successful extubation was done on third postoperative day and patient was discharged on tenth postoperative day without any complication.

A dental bridge impacted in the esophagus of a 43-year-old man was successfully removed using endoscopy, without any further complications. It is of utmost importance that the medical staff carefully assess the patient's dental condition, provide clear documentation, and notify the patient appropriately to prevent dental prosthesis-related complications and claims. Anesthesiologists also need to be more cautious in the perioperative period, even after extubation, because this complication may not be completely avoidable.

A 7-year-old girl visited the Samsung Medical Center emergency room for primary tooth aspiration during primary tooth extraction under conscious sedation with N₂O. The patient showed no signs of respiratory complications. Chest radiography and CT revealed a tooth in the right bronchi. Foreign body removal using rigid bronchoscopy was performed on the day of aspiration. With close monitoring of the airway in the pediatric ICU, extubation was performed the next day, and the patient was discharged the same day. The primary objective of this case report was to highlight the potential risk of aspiration associated with the use of N₂O gas for conscious sedation.

Background: Noninvasive positive pressure ventilation (NPPV) using facial or nasal mask have been widely used for several years in stable patients with chronic neuromuscular disease or central alveolar hypoventilation, and recently have been tried in patients with acute respiratory failure. In a few studies, NPPV was also used to rescue the patients with post-extubation respiratory failure. However, yet it has not been adopted as a weaning method in patients on long-term mechanical ventilation. So we performed this prospective clinical study to evaluate the usefulness of NPPV as a weaning method after removing endotracheal tube intentionally in patients on long-term mechanical ventilation. Method: Twelve patients who had been on invasive mechanical ventilation over 10 days were enrolled and 14 trials of NPPV were done. All had failed at least one weaning trial and showed ventilator dependence(pressure support requirement between 8-15cm $H_2O$, and PEEP requirement between 5-10cm $H_2O$), so tracheostomy was being considered. After removing the endotracheal tube, NPPV was applied using facial mask. Respiratory rate, arterial blood gas, pressure support level, and PEEP level were monitored just before intended extubation, at 30 minutes, 1 to 6, 6 to 12, 12 to 24 hours, 2nd day, and 3rd day following initiation of NPPV, and just before weaning from NPPV. The successful weaning was defined as spontaneous breathing off the ventilator for 48 hours or longer without respiratory distress. Results: The weaning through NPPV after intended extubation was successful in 7(50%) of 14 trials, and tracheostomy could be avoided in them. There were no differences in age, sex, APACHE III score, duration of invasive mechanical ventilation, baseline respiratory rate, $PaCO_2$ $PaO_2/FiO_2$, and ventilatory requirement(PS and PEEP) between the success and failure groups. In the success group, respiratory rate, pH, $PaCO_2$, and $PaO_2/FiO_2$ were not different between invasive MV and NPPV period. But in the failure group, pH decreased after 30 minutes of NPPV initiation compared with that of invasive MV($7.40\pm0.08$ vs. $7.34\pm0.06$, p<0.05). The causes of failure were worsening of ABG(n=3), retained tracheal secretion(n=2), mask intolerance(n=1), and flail chest(n=1). Conclusion: NPPV may be worth trying as a bridge method in weaning patients on long-term invasive mechanical ventilation.
