  • Observation of lateral position ventilation in invasive ventilation of patients with acute exacerbations of chronic obstructive pulmonary disease

    Objective To investigate the clinical significance of lateral position ventilation in the treatment of invasive ventilation in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Methods From October 2014 to December 2016, 60 eligible patients with AECOPD who meeting the inclusion criteria were randomly assigned to an intervention group (n=30) or a control group (n=30). Expectorant, antiasthmatic, anti-infective, invasive ventilation, bronchoscopy, analgesic sedation, invasive-noninvasive sequential ventilation, nutritional support, intensive care and other treatment were conducted in two groups, but lateral position ventilation was subsequently performed in the intervention group and the control group used half lateral position. Outcome measurements included pH, PaO2/FiO2, arterial partial pressure of carbon dioxide (PaCO2), heart rate (HR), respiratory rate (R) and air way resistance (Raw) before and one day after invasive ventilation, and duration of control of pulmonary infection (PIC), invasive mechanic ventilation (IMV), mechanic ventilation (MV) and intensive care unit (ICU) stay. Results Compared with before ventilation, the levels of PaO2/FiO2, PaCO2, HR, R and Raw were significantly changed in two groups after ventilation (P<0.05). One day later after ventilation, pH [interventionvs. control: (7.43±0.07) vs. (7.37±0.11)], PaO2/FiO2[(253.52±65.33) mm Hg (1 mm Hg=0.133 kPa) vs. (215.46±58.72) mm Hg] and PaCO2 [(52.45±7.15) mm Hg vs. (59.39±8.44) mm Hg] were statistically significant (P<0.05), but no significant difference was found in HR, R or Raw between two groups (P>0.05). Compared with the control group, PIC [(3.7±1.4) daysvs. (5.3±2.2) days], IMV [(4.0±1.5) days vs. (6.1±3.0) days], MV [(4.7±2.0) days vs. (7.3±3.7) days] and ICU stay [(6.2±2.1) days vs. (8.5±4.2) days] were significantly decreased (P<0.05) in the intervention group. Conclusions In AECOPD patients, invasive ventilation using lateral position ventilation can significantly improve arterial blood gas index, decrease Raw, shorten the time of PIC, IMV, MV and ICU stay.

  • Application of Noninvasive Positive Pressure Ventilation in Patients with Acute Left Heart Failure

    Objective To investigate the effects of noninvasive positive pressure ventilation (NPPV) on patients with acute left heart failure. Methods Twenty patients with acute left heart failure diagnosed between September 2013 and July 2014 were randomized into treatment group (n=10) and control group (n=10). Both groups used conventional sedations, diuretics and drugs that strengthened the heart and dilated the vessels, while early use of NPPV was applied in the experimental group. Arterial blood gas analysis [pH value, pressure of arterial carbon dioxide (PaCO2), and pressure of arterial oxygen (PaO2)], heart rate (HR), respiration, duration of Intensive Care Unit (ICU) stay and invasive mechanical ventilation, duration of overall mechanical ventilation, and success case numbers before and two hours after treatment were observed and analyzed. Results For the control group, two hours after treatment, PaO2 was (67.0±8.5) mm Hg (1 mm Hg=0.133 kPa), HR was (124±10) times/min, Respiration was (34±4) times/min, the duration of ICU stay was (6.0±1.1) days, invasive ventilation was for (32.0±3.1) hours, and the total time of mechanical ventilation was (32.0±3.1) hours. Those indexes for the treatment group two hours after treatment were: PaO2, (82.3±8.9) mm Hg; HR, (98±11) times/min; respiration, (24±4) times/min; the duration of ICU stay, (4.0±0.8) days; invasive ventilation time, (16.0±1.3) hours; the total time of mechanical ventilation, (26.0±1.8) hours. All the differences for each index between the two groups were statistically significant (P < 0.05). Conclusion Early application of NPPV can rapidly relieve clinical symptoms and reduce the medical cost for patients with acute left heart failure.

  • Comparative Study of Recruitment Maneuver in Mechanically Ventilated Patients after Fibrobronchoscopy

    ObjectiveTo investigate the effect of recruitment maneuver (RM) following fibrobronchoscopy in invasively mechanically ventilated (IMV) patients with excessive airway secretions or foreign body aspiration. MethodsFrom September 2012 to July 2014, 200 eligible patients were randomly assigned to intervention group (n=100) and control group (n=100) . Airway clearance by fibrobronchoscopy was conducted in both the two groups, but RM was subsequently performed only in the intervention group. Outcome measurements included oxygenation index, partial pressure of carbon dioxide (PaCO2), heart rate (HR), air way resistance (Raw) and dynamic lung compliance (Cdyn) before and 2 hours after treatment, and duration of IMV and Intensive Care Unit (ICU) stay were also analyzed. ResultsAfter treatment with fibrobronchoscopy, oxygenation index [intervention vs. control: (291.14±38.49) vs. (241.39± 35.62) mm Hg (1 mm Hg=0.133 kPa)], PaCO2 [(41.65±7.73) vs. (38.87±7.97) mm Hg] and Cdyn [(48.94±11.21) vs. (39.59±10.98) mL/cm H2O (1 cm H2O=0.098 kPa) ] were significantly increased, while HR [(95.41±20.59) , vs. (106.47±19.11) beats/min] and Raw [(17.87±8.32) vs. (23.98±7.88) cm H2O/(L·s)] were significantly decreased in both groups (P < 0.01) . Duration of IMV and ICU stay in the intervention group were (15.72±6.42) and (19.85±8.12) days respectively, while in the control group were (20.49±7.21) and (27.87±10.33) days. Compared with the control group, patients in the intervention group had lower Raw, duration of IMV and ICU stay, and higher Cdyn, oxygenation index, and PaCO2 (P < 0.01) , but no significant difference was found in HR (P > 0.05) . ConclusionIn mechanically ventilated patients with excessive airway secretion or foreign body aspiration, recruitment maneuver following fibrobronchoscopy is of great clinical importance, due to the decrease of the duration of mechanical ventilation and ICU stay by re-inflating the collapsing alveoli, improving pulmonary ventilation and gas exchange, lung compliance and diffusion capacity.

  • Retrospective studies of volume-OXygeneration index in predicting the effect of early non-invasive positive pressure ventilation in patients with type I Respiratory failure

    ObjectiveTo observe the predictive value of Volume OXygeneration (VOX) index for early non-invasive positive pressure ventilation (NIPPV) treatment in patients with type I Respiratory failure. MethodsRetrospective analysis was made on the patients with type I Respiratory failure admitted to the intensive care medicine from September 2019 to September 2022, who received early NIPPV treatment. After screening according to the discharge standard, they were grouped according to the NIPPV 2-hour VOX index. The observation group was VOX Youden index >20.95 (n=69), and the control group was VOX index ≤20.95 (n=64). Collect patient baseline data and NIPPV 2-hour, 12-hour, and 24-hour arterial blood gas values, and calculate NIPPV outcomes, intubation status, NIPPV usage time, hospital stay, and mortality rate. ResultsThere was a statistically significant difference in respiratory rate (RR) between the baseline data onto the two groups of patients, but others not. After early NIPPV treatment, the 2-hour oxygenation index (P/F) [(182.5 ± 66.14) vs. (144.1 ± 63.6) mm Hg, P<0.05] of the observation group showed a more significant increase. The failure rate of NIPPV intubation within 12 hours was lower (4.35% vs. 32.81%, P<0.05), the success rate of NIPPV withdrawal from 24 hours was higher (40.58% vs. 0%, P<0.05), and the failure rate of NIPPV intubation was lower (4.35% vs. 46.88%, P<0.05). The comparison of treatment outcomes showed that the intubation rates in the observation group (4.35% vs. 67.19%, P<0.05) was lower. The threshold of NIPPV 2-hour VOX index 20.95 was used as a predictor of Tracheal intubation, with sensitivity of 74.7% and specificity of 93.5%. ConclusionIn the early NIPPV treatment of patients with type I Respiratory failure, the NIPPV 2-hour VOX index>20.91 is taken as the evaluation index, which can better to predict the improvement in hypoxia and the risk of NIPPV failure Tracheal intubation, and has clinical significance.

  • Application of prone position in the treatment of patients with acute respiratory distress syndrome caused by pulmonary contusion

    ObjectiveTo explore the clinical significance of prone position in the treatment of patients with acute respiratory distress syndrome (ARDS) caused by pulmonary contusion.MethodsA retrospective analysis was conducted on pulmonary contusion patients in the Intensive Care Medicine (ICU) from January 2017 to April 2021. The patients were divided into a prone position group (n=121) and a control group (n=117) after screening. The patients' basic conditions, occurrence of ARDS (P/F<150 mm Hg), changes in vital signs, laboratory examinations, lung compliance and other changes after treatment, mechanical ventilation time, staying in ICU, complications, and mortality were recorded and conpared between the two groups.ResultsWhen ARDS [oxygenation index (P/F)<150 mm Hg] occurred, compared with 1 day later, the P/F [(125.7±15.3) vs. (209.5±22.4) mm Hg , P<0.05] and lung compliance [(64.6±4.8) vs. (76.0±5.4) mL/cm H2O, P<0.05] increased in the prone position group. Compare with the control group after 1 day of treatment ARDS (P/F<150 mm Hg), P/F [(209.5±22.4) vs. (126.1±19.5) mm Hg, P<0.05] and lung compliance [(76.0±5.4) vs. (63.5±5.5) mL/cm H2O, P<0.05] increased in the prone position group (P<0.05). Compare with the control group, the prone position group had shortened mechanical ventilation time and ICU stay time, less atelectasis, lower mortality (P<0.05), lower occurrence of pneumothorax (P>0.05).ConclusionProne position treatment for patients with pulmonary contusion after ARDS (P/F<150 mm Hg) can correct hypoxemia faster, improve lung compliance, reduce atelectasis, shorten mechanical ventilation time and stay time of ICU, and reduce mortality, hence it has clinical value.
