OBJECTIVETo evaluate the value of noninvasive intermittent positive-pressure ventilation (NIPPV) in treatment of patients with pneumoconiosis combined with respiratory failure.
METHODThree were 46 inpatients with pneumoconiosis combined with respiratory failure. Twenty-six inpatients treated with conventional therapy and NIPPV were categorized as treatment group; Twenty inpatients just treated by conventional therapy served as control group. Compared with the changes of HR, RR and arterial blood gas index (PH, PaCO2, PaO2) in two groups after treatment.
RESULTSThe effective ratio of treatment group was 88.5%, control group was 60%, which had significant difference (P < 0.05); The HR in treatment group after treatment was (95.38 +/- 10.75) beats per minute, control group was [(103.00 +/- 12.56) beats per minute; The RR in treatment group was (21.69 +/- 1.37) breaths per minute, control group was [(22.60 +/- 1.57) breaths per minute]; The PaCO2 in treatment group was (52.88 +/- 10.75)mm Hg, control group was [(59.66 +/- 11.49)mm Hg]; All of those were significantly decreased than those in control group (P < 0.05). The PaO2 in treatment group was (100.77 +/- 25.3) mm Hg, control group was [(71.82 +/- 17.94) mmHg]; Compared with the control group, PaO2 in the treatment group increased significantly (P < 0.05).
CONCLUSIONNIPPV is beneficial to pneumoconiosis combined with respiratory failure in different degrees.

3.Pulmonary Rehabilitation in Patients with Neuromuscular Disease.
Yonsei Medical Journal 2006;47(3):307-314
In neuromuscular disease (NMD) patients with progressive muscle weakness, respiratory muscles are also affected and hypercapnia can increase gradually as the disease progresses. The fundamental respiratory problems NMD patients experience are decreased alveolar ventilation and coughing ability. For these reasons, it is necessary to precisely evaluate pulmonary function to provide the proper inspiratory and expiratory muscle aids in order to maintain adequate respiratory function. As inspiratory muscle weakening progresses, NMD patients experience hypoventilation. At this point, respiratory support by mechanical ventilator should be initiated to relieve respiratory distress symptoms. Patients with adequate bulbar muscle strength and cognitive function who use a non-invasive ventilation aid, via a mouthpiece or a nasal mask, may have their hypercapnia and associated symptoms resolved. For a proper cough assist, it is necessary to provide additional insufflation to patients with inspiratory muscle weakness before using abdominal thrust. Another effective method for managing airway secretions is a device that performs mechanical insufflation-exsufflation. In conclusion, application of non-invasive respiratory aids, taking into consideration characterization of respiratory pathophysiology, have made it possible to maintain a better quality of life in addition to prolonging the life span of patients with NMD.

OBJECTIVETo estimate the feasibility and the efficacy of early extubation and sequential non-invasive mechanical ventilation (MV) in chronic obstructive pulmonary disease (COPD) with exacerbated hypercapnic respiratory failure.
METHODSTwenty-two intubated COPD patients with severe hypercapnic respiratory failure due to pulmonary infection (pneumonia or purulent bronchitis) were involved in the study. At the time of pulmonary infection control window (PIC window) appeared, when pulmonary infection had been significantly controlled (resolution of fever and decrease in purulent sputum, radiographic infiltrations, and leukocytosis) after the antibiotic and the comprehensive therapy, the early extubation was conducted and followed by non-invasive MV via facial mask immediately in 11 cases (study group). Other 11 COPD cases with similar clinical characteristics who continuously received invasive MV after PIC window were recruited as control group.
RESULTSAll patients had similar clinical characteristics and gas exchange before treatment, as well as the initiating time and all indices at the time of the PIC window. For study group and control group, the duration of invasive MV was (7.1 +/- 2.9) vs (23.0 +/- 14.0) days, respectively, P < 0.01. The total duration of ventilatory support was (13 +/- 7) vs (23 +/- 14) days, respectively, P < 0.05. The incidence of ventilator associated pneumonia (VAP) were 0/11 vs 6/11, respectively, P < 0.01. The duration of intensive care unit (ICU) stay was (13 +/- 7) vs (26 +/- 14) days, respectively, P < 0.05.
CONCLUSIONSIn COPD patients requiring intubation and MV for pulmonary infection and hypercapnic respiratory failure, early extubation followed by non-invasive MV initiated at the point of PIC window significantly decreases the invasive and total durations of ventilatory support, the risk of VAP, and the duration of ICU stay.

OBJECTIVETo observe the effect of early bronchoscopic sputum suction in elderly patients with acute heart and lung failure due to aspiration pneumonia.
METHODSComprehensive treatments were administered for 52 elderly patients with acute heart and lung failure resulting from aspiration pneumonia, and in 27 of the patients, bronchoscopic sputum suction was performed with the other 25 serving as the control group. The indices of the heart and lung functions (central venous pressure, left ventricular ejection fraction, arterial blood partial pressures of oxygen and carbon dioxide) were measured after the treatment and compared between the two groups.
RESULTSPatients receiving bronchoscopic suction showed faster recovery of normal central venous pressure and left ventricular ejection fraction and more rapid increment of arterial partial pressure of oxygen and reduction of carbon dioxide partial pressure than those without the suction (P<0.01).
CONCLUSIONEarly bronchoscopic sputum suction can be one of the effective emergency measures for rescuing acute heart and lung failure due to aspiration pneumonia.

BACKGROUNDSevere acute respiratory syndrome is frequently complicated by respiratory failure requiring ventilatory support. We aimed to compare the efficacy of non-invasive ventilation against invasive mechanical ventilation treating respiratory failure in this disease.
METHODSRetrospective analysis was conducted on all respiratory failure patients identified from the Hong Kong Hospital Authority Severe Acute Respiratory Syndrome Database. Intubation rate, mortality and secondary outcome of a hospital utilizing non-invasive ventilation under standard infection control conditions (NIV Hospital) were compared against 13 hospitals using solely invasive ventilation (IMV Hospitals). Multiple logistic regression analyses with adjustments for confounding variables were performed to test for association between outcomes and hospital groups.
RESULTSBoth hospital groups had comparable demographics and clinical profiles, but NIV Hospital (42 patients) had higher lactate dehydrogenase ratio and worse radiographic score on admission and ribavirin-corticosteroid commencement. Compared to IMV Hospitals (451 patients), NIV Hospital had lower adjusted odds ratios for intubation (0.36, 95% CI 0.164 - 0.791, P = 0.011) and death (0.235, 95% CI 0.077 - 0.716, P = 0.011), and improved earlier after pulsed steroid rescue. There were no instances of transmission of severe acute respiratory syndrome among health care workers due to the use of non-invasive ventilation.
CONCLUSIONCompared to invasive mechanical ventilation, non-invasive ventilation as initial ventilatory support for acute respiratory failure in the presence of severe acute respiratory syndrome appeared to be associated with reduced intubation need and mortality.

Although it is well known that the respiratory failure is a major cause of death in most patients with chronic neuromuscular disease, predominant respiratory dysfunction without severe involvement of limb muscles is an unusual complication of mitochondrial myopathy in adult age. We experienced two cases of mitochondrial myopathy with severe involvement of respiratory function and only mild involvement of limb muscles. One is a 16 year old female and another is a 22 year old male. The diagnosis is based on morphologic characteristics of "ragged red fibers" under the light microscope and abnormal mitochondrias on the electron microscope in the muscle biopsy.
