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.
Uveitis is a group of inflammatory diseases affecting the uveal tract, retina, retinal blood vessels and vitreous. Due to its complex etiology, various entities, diverse and lack of constancy in treatment, some patients can experience visual impairment and even loss. In view of the fact that blindness caused by uveitis is mostly incurable and occurs usually in young and middle-aged people, it accounts for an important part of blinding eye diseases and has attracted worldwide attention. With the continuous development of precision medicine, clinicians will face new problems and challenges in disease diagnosis, and further in-depth research is needed to explore more optimized and efficient diagnostic processes and examinations to improve the diagnosis of uveitis in China.
With the flourishing career of scientific research, the number of medical literature is in the explosion of growth. According to the statistics revealed by the Royal Society in March 2011, it showed that the proportion of published literature in China increased from 4.4% at the beginning of this century to 12.2%, and leaped into the second rank of the world. But the citations lagged behind the growth in number. In addition, the quality of medical literature relates to the reliability of results. Therefore, how to evaluate and improve the quality of medical literature is important. This paper will present some evaluation methods of credible medical literatures.
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.
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.
The pharmacy management of medical institutions is the basic condition for the pharmacy management of medical alliances. There are many common factors in the pharmacy management of each medical institution, and these common factors are the basic conditions for the pharmacy management of medical alliances. The pharmacy management of a medical alliance is composed of both shared aspects and aspects that meet the individual needs of different medical institutions. There are many problems in the primary medical institutions of the medical alliances, such as obsolete concepts of pharmacy management and weak pharmaceutical service capabilities. Pharmaceutical information collection is an important part in the pharmacy management of medical institutions, which can connect all aspects and better reflect the advantages of the special organization of the medical alliances. This paper explores pharmacy management in medical consortia for the specific organisational form of medical alliances, examines the basic situation of pharmacy management in different medical institutions in medical consortia, analyzes the basic conditions and basic characteristics of pharmacy management in medical consortia, so as to find a breakthrough in pharmacy management in medical consortia.
