ObjectiveTo investigate the variation regularity about volume of drainage after initial thyroidectomy, and to find out the time points of safety extubation and the time points of risk extubation.
MethodsBetween September 2013 and April 2014, the clinical date of 71 cases of thyroid tumor who underwent thyroidectomy were prospectively analyzed and completely random designed. The patients were indwelling drain after thyroidectomy, the volume of drainage liquid were registered at each point of time in period of 48 hours after operation and analyzed its the variation regularity.
ResultsThe volume of drainage fluid in 48 h after operation was gradually decreased in 71 patients. The reduce speed of volume of drainage fluid in the 12 h after operation was faster, then was significantly slower, and gradually stabilized. The amount of the drainage fluid reached the peak in 2 h after operation in 22 cases, and then gradually decreased and reached the stabilization.
ConclusionsThe 2 hours after thyroidectomy is the risk drainage removing time when is relatively safe. The 12 hours after thyroidectomy is the safety drainage removing time, after that there is no longer any meaning to keep drainage tube.
ObjectiveTo investigate the application value of noninvasive ventilation (NIV) performed in patients with unplanned extubation (UE) in intensive care unit (ICU).MethodsThis was a retrospective analysis. The clinical data, application of NIV, reintubation rate and prognosis of UE patients in the ICU of this hospital from January 2014 to December 2018 were reviewed, and the patients were assigned to the control group or the NIV group according to the application of NIV after UE. The data between the two groups were compared and the application effects of NIV in UE patients were evaluated.ResultsA total of 66 UE patients were enrolled in this study, including 44 males and 22 females and with an average age of (64.2±16.1) years. Out of them, 41 patients (62.1%) used nasal catheter or mask for oxygenation as the control group, 25 patients (37.9%) used NIV as the NIV group. The Acute Physiology andChronic Health EvaluationⅡ score of the control group and the NIV group were (18.6±7.7) vs. (14.8±6.3), P=0.043. The causes of respiratory failure in the control group and the NIV group were as follows: pneumonia 16 patients (39.0%) vs. 7 patients (28.0%), postoperative respiratory failure 7 patients (17.1%) vs. 8 patients (32.0%), chronic obstructive pulmonary disease 8 patients (19.5%) vs. 6 patients (24.0%), others 5 patients (12.2%) vs. 4 patients (16.0%), heart failure 3 patients (7.3%) vs. 0 patients (0%), nervous system diseases 2 (4.9%) vs. 0 patients (0%), which showed no significant difference between the two groups. Mechanical ventilation time before UE were (12.5±19.8) vs (12.7±15.2) d (P=0.966), PaO2 of the control group and the NIV group before UE was (114.9±37.4) vs. (114.4±46.3)mm Hg (P=0.964), and oxygenation index was (267.1±82.0) vs. (257.4±80.0)mm Hg (P=0.614). Reintubation rate was 65.9% in the control group and 24.0% in the NIV group (P=0.001). The duration of mechanical ventilation was (23.9±26.0) vs. (21.8±26.0)d (P=0.754), the length of stay in ICU was (34.4±36.6) vs. (28.5±25.8)d (P=0.48). The total mortality rate in this study was 19.7%. The mortality rate in the control group and NIV group were 22.0% and 16.0% (P=0.555).ConclusionPatients with UE in ICU may consider using NIV to avoid reintubation.
ObjectiveTo systematically review the effectiveness and safety of interventions which target to improve the rate of successful extubation in preterm infants.MethodsPubMed, Web of Science, Cochrane Library, Chongqing VIP database, China National Knowledge Infrastructure, and Wanfang Database were searched for articles published from the dates of establishment of databases to August 2020, which compared different noninvasive respiratory support models or different doses of caffeine to improve the rate of successful extubation in preterm infants in randomized controlled trials. The references of included articles were also retrieved. And then a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 33 randomized controlled trials involving 4 536 preterm infants were included. Compared with nasal continuous positive airway pressure (NCPAP), high-flow nasal cannula (HFNC) reduced the nose injury rate [odds ratio (OR)=0.29, 95% confidence interval (CI) (0.15, 0.57), P=0.000 3] and the pneumothorax rate [OR=0.18, 95%CI (0.06, 0.55), P=0.003]; nasal intermittent positive pressure ventilation (NIPPV) reduced the extubation failure rate [OR=0.33, 95%CI (0.23, 0.48), P<0.000 01], the reintubation rate [OR=0.36, 95%CI (0.20, 0.65), P=0.000 7], the respiratory failure rate [OR=0.33, 95%CI (0.17, 0.64), P=0.000 9], and the pneumothorax rate [OR=0.29, 95%CI (0.12, 0.70), P=0.006]; and biphasic positive airway pressure (BiPAP) reduced the reintubation rate [OR=0.21, 95%CI (0.09, 0.46), P=0.000 1]. Compared with low-dose caffeine, high-dose caffeine reduced the extubation failure rate [OR=0.44, 95%CI (0.32, 0.60), P<0.000 01] and the bronchopulmonary dysplasia rate [OR=0.69, 95%CI (0.48, 0.99), P=0.04], but increased the rate of tachycardia [OR=1.99, 95%CI (1.22, 3.25), P=0.006].ConclusionAccording to the current evidence, compared with NCPAP, NIPPV and BiPAP could be used to improve the rate of successful extubation in preterm infants, HFNC could be used to decrease the risk of nose injury and pneumothorax; the optimal dose of caffeine should be chosen after evaluating the risk of adverse reactions such as tachycardia.
Objective To explore the application value of failure mode and effect analysis (FMEA) in the risk management of unplanned extubation after esophageal cancer surgery. Methods A total of 1 140 patients who underwent esophageal cancer surgery in our department from January 2015 to May 2017 were selected as a control group, including 948 males and 192 females with an average age of 64.45±4.53 years. FMEA was used to analyze the risk management process of unplanned extubation. The potential risk factors in each process were found by calculating the risk priority number (RPN) value, and the improvement plan was formulated for the key process with RPN>125 points. Then 1 117 patients who underwent esophageal cancer surgery from June 2017 to December 2019 were selected as a trial group, including 972 males and 145 females with an average age of 64.60±5.22 years, and the FMEA risk management mode was applied.Results The corrective measures were taken to optimize the high-risk process, and the RPN values of 9 high-risk processes were reduced to below 125 points after using FMEA risk management mode. The rate of unplanned extubation in the trial group was lower than that in the control group (P<0.05). Conclusion The application of FMEA in the risk management of unplanned extubation after esophageal cancer surgery can reduce the rate of unplanned extubation, improve the quality of nursing, and ensure the safety of patients.
ObjectiveTo systematically evaluate the efficacy of high-flow nasal cannula oxygen therapy (HFNC) in post-extubation intensive care unit (ICU) patients.MethodsThe PubMed, Embase, Cochrane Library, CNKI, WanFang, VIP Databases were searched for all published available randomized controlled trials (RCTs) or cohort studies about HFNC therapy in post-extubation ICU patients. The control group was treated with conventional oxygen therapy (COT) or non-invasive positive pressure ventilation (NIPPV), while the experimental group was treated with HFNC. Two reviewers separately searched the articles, evaluated the quality of the literatures, extracted data according to the inclusion and exclusion criteria. RevMan5.3 was used for meta-analysis. The main outcome measurements included reintubation rate and length of ICU stay. The secondary outcomes included ICU mortality and hospital acquired pneumonia (HAP) rate.ResultsA total of 20 articles were enrolled. There were 3 583 patients enrolled, with 1 727 patients in HFNC group, and 1 856 patients in control group (841 patients with COT, and 1 015 with NIPPV). Meta-analysis showed that HFNC had a significant advantage over COT in reducing the reintubation rate of patients with postextubation (P<0.000 01), but there was no significant difference as compared with that of NIPPV (P=0.21). It was shown by pooled analysis of two subgroups that compared with COT/NIPPV, HFNC had a significant advantage in reducing reintubation rate in patients of postextubation (P<0.000 01). There was no significant difference in ICU mortality between HFNC and COT (P=0.38) or NIPPV (P=0.36). There was no significant difference in length of ICU stay between HFNC and COT (P=0.30), but there had a significant advantage in length of ICU stay between HFNC and NIPPV (P<0.000 01). It was shown by pooled analysis of two subgroups that compared with COT/NIPPV, HFNC had a significant advantage in length of ICU stay (P=0.04). There was no significant difference in HAP rate between HFNC and COT (P=0.61) or NIPPV (P=0.23).ConclusionsThere is a significant advantage to decrease reintubation rate between HFNC and COT, but there is no significant difference in ICU mortality, length of ICU stay or HAP rate. There is a significant advantage to decrease length of ICU stay between HFNC and NIPPV, but there is no significant difference in ICU mortality, reintubation rate or HAP rate.
