Efects of closed airway management on distribution and drug susceptibility of pathogenic bacteria in lower respiratory tract of mechanical ventilated patients

0bjective To compare the effect of closed airway management system and open suction system on distribution and drug susceptibility of pathogenic bacteria in lower respiratory tract of mechanical ventilated patients.Methods Fifty-nine cases in ICU who received mechanical ventilation for more than 48 h from May 2006 to Dec 2006 were randomly divided into two groups.Group A(29 patients)received closed—tracheal suction and Group B(30 patients)received open-tracheal suction.Quantitative bacteriological culture and sensitivity of antibacterial drugs were conducted on lower respiratory tract secretion samples.Results In group A，a total of 91 strains were isolated，in which a single pathogen infection(41.4％)was the most frequent，followed by mixed infection of two pathogens(34.5％)and three or more pathogens(24.1％).In group B，a total of 141 strains were isolated，in which three or more pathogen infection(53.33％)was the most frequent，followed by two pathogen infection(30％)and a single pathogen infection(16.7％ ).Pathogen distribution between the two groups was not significantly different(Pgt;0.05).Drug susceptibility test did not show significant difference in main pathogens between the two groups(Pgt;0.05).Conclusions Closed airway management system can reduce the infection or colonization of mixed pathogens，but can not change the distribution and drug susceptibility of pathogens.

Comparison of Laryngeal Tube Suction II and LMAProseal for Airway Management in Elective Surgery: Asystematic Review

摘要:目的:评价II代引流型喉管(LTS II)和Proseal喉罩(PLMA)在择期手术中应用效果。方法:检索了Cochrane图书馆(2009年第3期)、Pubmed(1950～2009)、EMBase(1989～2009)、CNKI(1979～2009)、VIP(1989～2009)、CBM(1978～2009)中相关II代引流型喉管(LTS II)和Proseal喉罩在择期手术中应用的随机对照试验(RCT),同时筛检纳入文献的参考文献。由2名研究者对文献质量进行严格评价和资料提取,根据指标相应异质性进行描述性分析或Meta分析(RevMan 5.0)。结果:共纳入3个RCT,共244例研究对象,文献质量均为B级。3个RCT的结果显示与PLMA相比,LTS II具有相似的首次置入成功率(P=0.45)、术毕即刻上呼吸道损伤发生率(P=1.00)、术后24 h咽痛发生率(P=0.81)、术后24 h吞咽困难发生率(P=0.12)。2个RCT的结果显示两组引流管置入均较容易。1个RCT的结果显示两组的操作者主观评价相近(OR=1.86,95%CI 0.39～ 8.99)。气道封闭效果由于采用方法学差异性较大,指标也不尽相同,尚不能得出准确结果。结论:LTS II在择期手术中用于气道管理具有较好的前景。但是现时仍不宜用于需在择期术中进行控制通气的病人。关于气道封闭效果,尚需采用更合理规范的指标、更高质量的研究设计进一步研究。Abstract: Objective: To assess the efficacy of laryngeal tube suction II (LTS II) and LMAProseal (PLMA) for airway management in elective surgery. Methods:We searched Cochrane Library (2009),Pubmed (19502009)、EMBase (19892009),CNKI (19792009),VIP (19892009),CBM (19782009). The quality of the trials was assessed by two reviewers independently. RevMan 5.0 software provided by the Cochrane Collaboration was used for statistical analysis. Results:Three studies involving 244 participants were included. Same rates of fist successful attempt (P=0.45),upper airway trauma (P=1.00),sore throat (P=0.81) and dysphagia (P=0.12) were observed in LTS II and PLMA in all studies. Two studies indicated that the insertion of gastric tube was easy in both groups. The similarity of subjective maneuverability in two groups was reported in one study (OR=1.86, 95%CI 0.39 to 8.99). The correct result of effectiveness of airway seal could not be made because of various methods and measurements. Conclusion:LTS II have a good perspective in the airway management. Otherwise, it is not safe for patient required control ventilation because of lack of evidence on the effectiveness of airway seal. More RCTs of high quality need to be undertaken in the future.

Evaluation of Treating Patients Undergoing Open Chest Surgery with Airway Management Drugs and Moderate or Severe COPD

ObjectiveTo evaluate the effect of airway management drugs on the respiratory function and postoperative recovery of patients who had moderate or severe chronic obstructive pulmonary diseases(COPD) undergoing an open chest surgery. MethodThere were a total of 22 patients suffering from both lung cancer, esophageal cancer or gastroesophageal junction carcinoma and moderate to severe COPD(of which there were 16 males and 6 females; accepting traditional operation 5 cases and minimally-invasive operation 17 cases; lung cancer 16 cases, esophageal cancer 4 cases and gastroesophageal junction carcinoma 2 cases as the observation group). To statistic the respiratory function and arterial blood gas analysis before and after treating with airway management drugs. And compare the postoperative pulmonary complications(PPCs) and hospital-stay with 50 patients who have no COPD(of which there were 34 males and 16 females; accepting traditional operation 17 cases and minimally-invasive operation 33 cases; lung cancer 35 cases, esophageal cancer 11 cases and gastroesophageal junction carcinoma 4 cases as the control group). ResultThere was a statistical difference of forced expiratory volume in one second(FEV1), forced vital capacity(FVC) and maximal voluntary ventilation(MVV) after the above treatment by 7 to 10 days and comparing with prior treatment(P<0.05). Partial pressure of oxygen(PaO2) increased with no statistical difference(P>0.05) while PaCO2 decreased with a statistical difference(P<0.05）. Comparing with patients without COPD, the incidences of PPCs and postoperative hospital stay were of no statistical difference(P>0.05). ConclusionPatients with moderate or severe COPD with airway management drugs(antibiotics,glucocorticoids, bronchodilators and phlegm dissolving agent) in perioperative period could improve the respiratory function and operation tolerance effectively, reduce the incidence of PPCs and shorten postoperative hospital stay.

Different airway management strategies in out-of-hospital cardiac arrest: a systematic review

ObjectiveTo compare the effects of different airway management strategies on outcomes of patients with out-of-hospital cardiac arrest (OHCA).MethodsWe searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, and WanFang Data for relevant studies comparing the influence of different airway management strategies on outcomes of OHCA patients. The deadline was up to 31st May, 2019. Grading of Recommendations Assessment, Development and Evaluation system 3.6 was used for quality assessment, and RevMan 5.3 software was used for meta-analysis. Odds ratio (OR) and 95% confidence interval (CI) were used to conduct the comparison. Results A total of 20 studies were finally enrolled, including 880 567 OHCA patients. Compared with supraglottic airway (SGA), bag-valve mask (BVM) improved the rate of survival to discharge of OHCA patients [OR=1.45, 95%CI (1.01, 2.08), P=0.04], while the rate of return of spontaneous circulation (ROSC) was not improved (P>0.05); in the subgroup analysis, BVM and SGA had similar effect on the rate of ROSC and the rate of survival to discharge in Asian countries (P>0.05), while BVM performed better than SGA in the two rates in European and American countries. BVM and endotracheal intubation (ETI) had similar effect on the two rates (P>0.05). In Asian countries, ETI performed better than BVM in the rate of ROSC [OR=0.63, 95%CI (0.49, 0.81), P=0.000 3], and there was no statistically significant difference in the rate of survival to discharge between ETI and BVM (P>0.05); while in European andAmerican countries, BVM performed better than ETI in the rate of survival to discharge [OR=3.10, 95%CI (2.69, 3.56), P<0.000 01], and there was no statistically significant difference in the rate of ROSC between ETI and BVM (P>0.05). Compared with SGA, ETI improved the rate of ROSC [OR=0.68, 95%CI (0.62, 0.76), P<0.000 01] and the rate of survival to discharge [OR=0.89, 95%CI (0.81, 0.98), P=0.02]. In Asian countries, ETI performed better than SGA in the two rates (P<0.05); while in European and American countries and New Zealand, ETI performed better than SGA in the rate of ROSC (P<0.05), but there was no statistically significant difference in the rate of survival to discharge (P>0.05). Conclusions Different airway management strategies have differente effects on OHCA patients. The optimal airway management strategy when rescuing OHCA patients might be selected based on local emergency medical service system conditions.

Artificial Airway Management for Inhalation Injury Patients Undergoing Tracheotomy

ObjectiveTo summarize the experiences of artificial airway management for inhalation injury patients undergoing tracheotomy. MethodsA retrospective analysis was made on the clinical data of 16 patients with inhalation injury who accepted artificial airway implantation after tracheotomy from January 2012 to October 2014. Certain measures were taken for the patients such as timely sputum suction in a correct way, effective airway moist, timely airway lavage, strict aseptic operation, reasonable position management, dynamic observation and health education. ResultsFifteen patients were cured, and one died. Among the cured patients, there were one case of catheter change due to blocked sputum, and one case of catheter outward portion sliding depth adjusting. ConclusionStrengthening artificial airway management after tracheotomy is the key to keep airway unobstructed, to prevent complications, and to guarantee the safety and a speedy recovery of patients.
