Methods The clinical data of 120 patients who underwent coronary stenting between January and March 2011 were retrospectively analyzed. Patients were randomly divided into control group (n=58) treated with conventional coronary stent extubation and experiment group (n=62) treated with conventional coronary stent extubation and professional nursing intervention care. Results In 120 patients, VVRs occurred in 10 including 8 in the control group and 2 in the experiment group. The difference between the two groups was significant (Plt;0.05). Conclusion The coronary stent implantation with specific nursing interventions can effectively reduce the vascular vagal reflex, and leads to a higher success rate of the surgery.
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.
Objective To explore the correlations between the time of tracheal extubation and the intraoperative basic factors of ex vivo liver resection followed by autotransplantation in patients with advanced hepatic alveolar echinococcosis (HAE), and analyze the change trend of blood gas analysis during operation. Methods The data of 24 patients with advanced HAE who underwent ex vivo liver resection followed by autotransplantation in West China Hospital of Sichuan University between February 2014 and August 2017 were retrospectively analyzed. Results There were significant correlations between the extubation time and the duration of anesthesia (r=0.472, P=0.031), the amount of bleeding (r=0.524, P=0.015), the amount of erythrocyte suspensions infusion (r=0.627, P=0.002), and the amount of plasma infusion (r=0.617, P=0.003). There was no statistical difference in extubation time between patients with and without pulmonary complications in 3 months postoperatively [(23.74±15.84), (15.52±19.40) h, P=0.327]. Compared with those arterial blood gas results before the interruption, the pH value, blood glucose, lactic acid and base excess were statistically significantly different (P<0.05) at each time point after the interruption. Blood potassium increased at the end of operation compared with that before interruption (P<0.05); and the free calcium after blocking and opening increased with a temporary decrease (P<0.05); the hemoglobin decreased significantly after interruption and clamping (P<0.05). Conclusions Anesthesia length and bleeding should be reduced in ex vivo liver resection followed by autotransplantation, thus the extubation time would be shortened and the prognosis of the patients might be improved. Because of the longer anhepatic phase, the blood gas analysis varies largely. During operation, blood gas analysis and monitoring should be strengthened, and the acid-base balance and electrolytes should be maintained in time.
ObjectiveTo explore the feasibility of early chest tube removal following single-direction uniportal video-assisted thoracoscopic surgery (S-UVATS) anatomical lobectomy. MethodsThe clinical data of consecutive VATS lobectomy by different surgeons in Xuzhou Central Hospital between May 2019 and February 2022 were retrospectively reviewed. Finally, the data of 1 084 patients were selected for analysis, including 538 males and 546 females, with a mean age of 61.0±10.1 years. These patients were divided into a S-UVATS group with 558 patients and a conventional group (C-UVATS) with 526 patients according to the surgical procedures. The perioperative parameters such as operation time, blood loss were recorded. In addition, we assessed the amount of residual pleural effusion and the probability of secondary thoracentesis when taking 300 mL/d and 450 mL/d as the threshold of chest tube removal. ResultsTumor-negative surgical margin was achieved without mortality in this cohort. As compared with the C-UVATS group, patients in the S- UVATS group demonstrated significantly shorter operation time (P<0.001), less blood loss (P=0.002), lower rate of conversion to multiple-port VATS or thoracotomy (P=0.003), but more stations and numbers of dissected lymph nodes as well as less suture staplers (P<0.001). Moreover, patients in the S-UVATS demonstrated shorter chest tube duration, less total volume of thoracic drainage and shorter postoperative hospital stay, with statistical differences (P<0.001). After excluding patients of chylothorax and prolonged air leaks>7 d, subgroup analysis was performed. First, assuming that 300 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, patients in the S-UVATS group would report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Second, assuming that 450 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, the S-UVATS group would also report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Further multivariable logistic regression analysis indicated that S-UVATS was significantly negatively related to drainage volume>1 000 mL (P<0.05); whereas combined lobectomy, longer operation time, more blood loss and air leakage were independent risk factors correlated with drainage volume>1 000 mL following UVATS lobectomy (P<0.05). ConclusionThe short-term efficacy of S-UVATS lobectomy is significantly better than that of the conventional group, indicating shorter operation time and less chest drainage. However, early chest tube removal with a high threshold of thoracic drainage volume probably increases the risk of secondary thoracentesis due to residual pleural effusion.
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 assess the safety of the removal of pericardial and mediastinal drain within different drainage volume after cardiac valvular replacement surgery.MethodsBetween July 2013 and July 2017, 201 patients with rheumatic heart disease (CHD) were treated with valve replacement in our hospital, including 57 males and 144 females, aged 15 to 72 years. They were divided into two groups according to the amount of 24-h drainage before the drain removal: a group one with 24-h drainage volume≤50 ml (n=127) and a group two with 24-h drainage volume>50 ml (n=74). The postoperative hospital stay and the incidence of severe complications between the two groups were compared.ResultsThere was no difference between the two groups in the baseline information or the incidence of severe pericardial effusion and tamponade, while the group two tended to have a shorter length of hospital stay after surgery (8.0 d vs. 7.5 d, P=0.013).ConclusionIn CHD patients undergoing valvular surgery, compared with a relatively low amount of drainage before the drain removal, drawing the tube at a greater amount of drainage (24-h drainage volume>50 ml) will shorten the length of hospital stay after cardiac surgery while incidence of severe complications remains the same.
