RESUMO

Objective To analyze the feasibility of body surface electrodes instead of multipair esophageal electrodes for the evaluation of neural respiratory drive in patients with COPD. Methods Diaphragm electromyo-gram(EMG)from body surface electrodes and multipair esophageal electrodes,was recorded in 29 patients with stable COPD recruited from outpatient clinic. Changes of neural respiratory drive of two kinds of electrodes during resting and maximal isocapnic ventilation (MIV) were observed before and after inhalation of bronchodilators. Results Ventilation significantly improved ,RMS-sur and RMS-eso significantly decreased after the inhalation of bronchodilators during resting and MIV. RMS-sur and RMS-eso were significantly correlated(r=0.660,P<0.01). Conclusion EMG from the surface electrodes may be a useful and noninvasive technique to evaluate neural respi-ratory drive in patients with COPD.

RESUMO

Objective To explore the efficacy of noninvasive positive pressure ventilation technology com-bined with respiratory stimulant in the treatment of pulmonary encephalopathy in patients with COPD.Methods For-ty -eight COPD patients with early pulmonary encephalopathy were included.They were randomly divided into the treatment group and control group.The treatment group was treated by not only regular treatment and noninvasive posi-tive pressure ventilation technology,but also respiratory stimulant.The control group was only treated by regular treat-ment and noninvasive positive pressure ventilation technology.The indexes were recorded,including tracheal intubation rate,clinical recovery rate,mortality,Glasgow coma score,arterial blood gas analysis and adverse reactions.Results Compared with the control group,the arterial blood gas analysis of treatment group on the 2h,24h and 72h were statis-tically significant different(P <0.05).The GCS score on the 24h and 72h were also statistically significant different [24h,(13.4 ±1.6)vs.(11.8 ±2.1),P <0.05;72h,(14.6 ±1.5)vs.(12.4 ±2.4),P <0.05].The treatment group had lower tracheal intubation rate(12% vs.56.5%,P =0.001),shorter consciousness recovery time[(3.0 ± 0.5)h vs.(5.6 ±0.7)h,P =0.023],shorter hospitalization time in ICU[(12.6 ±1.5)d vs.(19.2 ±1.8)d,P =0.004]and better clinical recovery(22 /25 vs.10 /23,P =0.001)than the control group.But the mortality rate had no significant difference between the two groups(1 /25 vs.4 /23,P =0.129).Conclusion NIPPV combined with respiratory stimulant is an effective,safe and simple method for treatment of COPD complicated with pulmonary encephalopathy.It can significantly improve the clinical symptoms and the index of arterial blood gas analysis,and it can shorten consciousness recovery time and decrease tracheal intubation rate.But close observation must be carried out,and the invasive mechanical ventilation should be promptly executed in case of emergency or exacerbation.

RESUMO

Objective To evaluate the efficacy of noninvasive positive pressure ventilation (NIPPV) in the treatment of early acute respiratory distress syndrome(ARDS) Methods 12 patients with early ARDS were errolled in the study All the patients pulltiled the criteria of ARDS and no improvement after high flow oxygen therapy via mask NIPPV was used because the patients and their family refused intubation Pressure support ventilation (PSV) and positive end expiratory pressure (PEEP) were used via facial mask with Vison or BiPAP ventilator PEEP were set at 8~12 cm H 2 O with 4~6 PSV level Results The baseline respiratory frequency(RR)was (36?4)bpm,PaO 2 was (55?9)mm Hg and oxygen index (OI)was (127?4)mm Hg At final,8 patients survived (S group) and 4 patients died (F group) After 4~6 h treatment with NIPPV,in S group,RR decreased to (32?1 2)bpm ( P

RESUMO

0.05.Conclusion NPPV can be used in the general ward for those of acute exacerbations of COPD (AECOPD) complicated with respiratory failure;prognosis is better if the patient is improved in blood gas analysis,respiratory and heart rate after ventilating 1~2 hours and 24 hours.
