OBJECTIVETo review the clinical features and therapeutic experience in children with plastic bronchitis.
METHODSFourteen children with plastic bronchitis were reviewed retrospectively, 12 of which were under two years old. The clinical features are characterized by sudden onset, episodes of profound hypoxia and respiratory tract obstruction. SaO2 was between 0.70 and 0.80 even with mask oxygen inhalation. Eight cases were pyretic, 4 cases expectorated jel-like bronchial casts. The chest X-ray picture showed patchy consolidation or atelectasis unilaterally (10 cases) or bilaterally (2 cases). Pulmonary marking thickening and patchy shadow were observed in 2 cases. Twelve cases underwent rigid bronchoscopy and the bronchial casts were removed. Two cases underwent endotracheal intubation.
RESULTSEight cases of 12 children received therapeutic bronchoscopy were cured. Other 4 cases had second therapeutic bronchoscopy and bronchial casts were removed again in 3 cases, one died from pulmonary hemorrhage. Two cases who underwent endotracheal intubation died from the multiple organ failure (MOF). Pathologic results showed:the bronchial casts were composed mainly of mucus and fibrin, inflammatory cell infiltrate were observed in 6 cases (Type 1, inflammatory), no cellular infiltrate occurred in 8 cases (Type 2, acellular).
CONCLUSIONSPlastic bronchitis is a severe and dangerous disease. The branching plastic casts may obstruct part or the entire tracheobronchial, causing respiratory failure. Bronchoscopy and pathologic examination are essential for it's diagnosis and treatment.

3.Effect of orthognathic surgery on the posterior airway space (PAS).
Annals of the Academy of Medicine, Singapore 2008;37(8):677-682
Orthognathic surgery has been used regularly to treat dentofacial deformities. The surgical procedures affect both the facial appearance as well as the posterior airway space (PAS). Our current literature indicates that setback procedures produce an inferior repositioning of the hyoid bone and posterior displacement of the tongue and the soft palate. These movements cause anteroposterior and lateral narrowing of the PAS. Most authors agree that these effects are permanent. The PAS changes in turn produce an adaptive posturing, with an increased craniocervical angle to open up the PAS. Even though most patients do not display snoring and obstructive sleep apnoea (OSA) post-surgery, there is certainly an increased possibility in patients with already compromised airways. Therefore, patients who are undergoing orthognathic surgery should be screened for excessive daytime somnolence, snoring, increased body mass index (BMI) and medical conditions related to OSA and sent for an overnight polysomnography (PSG) if OSA is suspected. Then the proposed treatment plan may be modified according to the risk of potential airway compromise or even to improve it. Conversely, advancement of the maxilla and mandible causes widening of the airway in both the anteroposterior and lateral dimensions. This effect would translate to better airflow and decreased airway resistance. This is supported by the evidence showing high success rates when orthognathic surgery, especially maxillomandibular advancement (MMA), is utilised to treat OSA.

Obstructive fibrinous tracheal pseudomembrane is a rare, but potentially fatal complication associated with endotracheal intubation. It has been known that the formation of tracheal pseudomembrane is related with intracuff pressure during endotracheal intubation or infectious cause. But in the patient described in this case, pseudomembrane formation in the trachea was associated with subglottic epithelial trauma or caustic injuries to the trachea caused by aspirated gastric contents during intubation rather than tracheal ischemia due to high cuff pressure. We report a patient with obstructive fibrinous tracheal pseudomembrane after endotracheal intubation who presented with dyspnea and stridor and was treated successfully with mechanical removal using rigid bronchoscopy.

OBJECTIVETo investigate the therapeutic effects of upper airway stenosis after Le Fort III osteotomy and midfacial distraction osteogenesis (DO).
METHODSEleven cases (age, 5-16 yrs) with severe midface dysostosis complicated with exophthalmos, anterior crossbite and upper airway stenosis were treated by using Le Fort III osteotomy and midfacial DO from August 2000 to February 2007. The 3D reconstruction of the upper-airway from CT data was used to evaluate the upper airway volume before and after the operation. And meanwhile polysomnography was carried out to demonstrate the upper airway functional changes.
RESULTSThere was a 64.3% mean increase [mean, (9.13 +/- 6.94) ml, P < 0.05] in upper airway volume in the 11 cases after the operations. It showed that there was significant improvements in the indexes of polysomnography after the operations, such as apnea and hypopnea index, average SaO2, minimum oxygen saturation and snore index.
CONCLUSIONSThe Le Fort III osteotomy and midfacial distraction osteogenesis can efficiently relieve the symptoms of upper-airway stenosis in severe midfacial dysostosis.

BACKGROUNDIn China, tracheobronchial foreign body (TFB) aspiration, a major cause of emergency episode and accident death in children, remains a challenge for anesthetic management. Here, we share our experience and discuss the anesthetic consideration and management of patients with TFB aspiration.
METHODSThis was a single-institution retrospective study in children with an inhaled foreign body between 1991 and 2010 that focused on the complications following rigid bronchoscopy (RB). Data including the clinical characteristics of patients and TFB, anesthetic method, and postoperative severe complications were analyzed by different periods.
RESULTSDuring the 20-year study period, the charts of 3149 patients who underwent RB for suspected inhaled TFB were reviewed. There were 2079 male and 1070 female patients (1.94:1). A nut (84%) was the most commonly inhaled object. The study revealed a 9% (n = 284) overall rate of severe postoperative complications related to severe hypoxemia, laryngeal edema, complete laryngospasm, pneumothorax, total segmental atelectasis, and death with incidences of 3.2%, 0.9%, 1.3%, 0.3%, 0.3%, and 0.1%, respectively. The rates of preoperative airway impairment, negative findings of TFB, and adverse postoperative events have been on the rise in the past 5 years.
CONCLUSIONSThe survey results confirmed that hypoxemia remains the most common postoperative complication in different periods. Both controlled ventilation and spontaneous ventilation were effective during the RB extraction of the foreign body at our hospital in the modern technique period. An active respiratory symptom was commonly seen in the groups with negative findings.

OBJECTIVETo observe the therapeutic effects of Le Fort III osteotomy and midface distraction osteogenesis (DO) on the upper-airway narrow.
METHODSSince 2000, 11 cases (10 cases of Crouzon syndrome and 1 case of Apert syndrome) with severe midface deficiency were treated with Le Fort III osteotomy and midface DO. The section area of different parts of upper-airway were tested by computer assistants image measurement preoperatively and postoperatively. Some patients received sleep function monitoring.
RESULTSThe face appearance and the function of upper-airway improved significantly after Le Fort III osteotomy and Midface DO. The section area at the level of posterior nasal spine and uvula increased obviously after treatment (P < 0.05), however the section area at the level of epiglottis and separation between airway and esophagus were not obviously enlarged (P > 0.05).
CONCLUSIONSMidface DO after Le Fort III osteotomy can effectively improve the upper-airway narrow, especially the upper part from uvula.

OBJECTIVETo explore the diagnostic and therapeutic methods for perioperative children with congenital heart disease (CHD) with airway stenosis in pediatric intensive care unit (PICU).
METHODFiberoptic bronchoscopy was used for the diagnosis of 100 CHD cases in PICU who were clinically considered to have possible airway malformation because of complicated difficult-to-control lung infection, atelectasis and failure with the ventilator after surgery from January 2010 to October 2011. Cases who were confirmed to have severe airway stenosis by bronchoscopy and weaning from the ventilator after surgery were treated with balloon expandable stents into the desired position in the bronchoscopy.
RESULTThere were 73 cases (73%) of CHD patients with airway abnormalities, including 31 cases of severe stenosis (31%), moderate stenosis in 29 cases (29%), mild stenosis in 13 cases (13%). Nine of the 10 children in whom the mechanical ventilation was hard to be stopped after surgery because of severe airway stenosis were weaned from mechanical ventilation successfully by fiberoptic bronchoscopy, while one case died from primary disease with severe sepsis after the placement of bronchial stents.
CONCLUSIONCHD children with difficult-to-control lung infection, atelectasis and failure with ventilator after surgery are often complicated with airway abnormalities. The therapeutic bronchoscopy with airway stent can be used for cases with weaning from the ventilator because of severe airway stenosis.

OBJECTIVETo explore the epidemiological characteristics of inhalation injury and to summarize the clinical application experience of diagnostic standard of burn of larynx.
METHODSMedical records of 443 patients with inhalation injury admitted to our burn unit from January 1999 to June 2013 were analyzed, including gender, age, severity of inhalation injury, complications and diseases before injury; total area and that of full-thickness burn injury, admission time after burn, and burn condition of larynx of patients with different degrees of inhalation injury; treatment and outcome including rate, time, and complication of tracheotomy, mortality, and cause of death. Data were processed with nonparametric Kruskal-Wallis test and chi-square test. The relationship between severity of inhalation injury and total burn area, degree of burn of larynx, tracheotomy rate, and mortality was assessed by Spearman correlation analysis.
RESULTS(1) Among the patients, there were 353 (79.7% ) male and 90 (20.3% ) female, with the ratio of male to female 4:1. There were 64 (14.4%) patients younger than or equal to 20 years, 203 (45.8%) patients older than 20 years and younger than or equal to 40 years, 144 (32.5%) patients older than 40 years and younger than or equal to 60 years, and 32 (7.2%) patients older than 60 years. The numbers of patients with mild, moderate, and severe inhalation injury were respectively 297, 108, and 38. Seven patients suffered from complications, and 21 patients had diseases before injury. There were statistically significant differences among the patients with different degree of inhalation injury in regard to total burn area and full-thickness burn area (with H values respectively 73.752 and 142.830, P values below 0.01), while no statistically significant difference was observed in admission time after burn ( H = 1.528, P > 0.05). Correlation analysis showed that severity of inhalation injury was positively correlated with total burn area (r = 0.399, P < 0.001). Among the patients with mild inhalation injury, incidences of patients with mild, moderate, and severe burn of larynx were respectively 68.0% (202/297), 32.0% (95/297), and 0, and those among the patients with moderate inhalation injury were respectively 0,53.7% (58/108), and 46.3% (50/108). There were statistically significant differences in degree of burn of larynx of patients with different degree of inhalation injury (χ2 = 336.703, P < 0.001). Correlation analysis showed that severity of burn of larynx was positively correlated with severity of inhalation injury (r = 0.700, P < 0.001). (2) The rate of tracheotomy was 37.02% (164/443). The rates of tracheotomy in patients with mild, moderate, and severe inhalation injury were respectively 10.44% (31/297), 87.96% (95/108), and 100.00% (38/38), χ2 = 271.654, P < 0.001. Correlation analysis showed that the rate of tracheotomy was positively correlated with severity of inhalation injury (r = 0.784, P < 0.001). Tracheotomy was done mainly within 6 h post burn (63.4%, 104/164). The incidence rate of complication of tracheotomy was 5.5% (9/164). (3) Thirty-one patients died, with a mortality rate of 7.00%. The mortality rates of patients with mild, moderate, and severe inhalation injury were respectively 1.01% (3/297), 12.96% (14/108), and 36.84% (14/38), H = 74.273, P < 0.001. It was found that the mortality was positively correlated with severity of inhalation injury (r = 0.371, P < 0.001). The causes of death of the patients were respectively sepsis (14, 45.2%), respiratory failure (7, 22.6%), airway obstruction (2, 6.5%), airway hemorrhage (2, 6.5%), cerebral hemorrhage (2, 6.5%), cardiac accident (2, 6.5%), and diabetes insipidus (1, 3.2%), and 1 (3.2%) patient quit treatment and discharged from hospital for economic reason.
CONCLUSIONSAmong the patients with inhalation injury, male is dominated in number, and the young adults formed the highest constituent ratio. The severity of inhalation injury was correlated with total burn area, severity of burn of larynx, tracheotomy rate, and mortality. With the guidance of diagnostic criteria of burn of larynx and indication of tracheotomy, the risk of laryngeal obstruction can be eliminated. The early preventive tracheotomy can decrease the difficulty and risk of the operation.
