ABSTRACT
@#Objective To analyze the occurrence of postoperative pulmonary complications (PPC) and the risk factors in patients with spontaneous pneumothorax who underwent micro single-port video-assisted thoracoscopic surgery (VATS). Methods A total of 158 patients with spontaneous pneumothorax who underwent micro single-port VATS in our hospital from April 2017 to December 2019 were retrospectively included, including 99 males and 59 females, with an average age of 40.53±9.97 years. The patients were divided into a PPC group (n=21) and a non-PPC group (n=137) according to whether PPC occurred after the operation, and the risk factors for the occurrence of PPC were analyzed. Results All 158 patients successfully completed the micro single-port VATS, and there was no intraoperative death. The postoperative chest tightness, chest pain, and dyspnea symptoms basically disappeared. During the postoperative period, there were 3 patients of pulmonary infection, 7 patients of atelectasis, 4 patients of pulmonary leak, 6 patients of pleural effusion, 1 patient of atelectasis and pleural effusion, and the incidence of PPC was 13.29% (21/158). Multivariate logistic regression analysis showed that lung disease [OR=32.404, 95%CI (2.717, 386.452), P=0.006], preoperative albumin level≤35 g/L [OR=14.912, 95%CI (1.719, 129.353), P=0.014], severe pleural adhesions [OR=26.023, 95%CI (3.294, 205.557), P=0.002], pain grade Ⅱ-Ⅲ 24 hours after the surgery [OR=64.024, 95%CI (3.606, 1 136.677), P=0.005] , age [OR=1.195, 95%CI (1.065, 1.342), P=0.002], intraoperative blood loss [OR=1.087, 95%CI (1.018, 1.162), P=0.013] were the risk factors for PPC after micro single-port VATS. Conclusion There is a close relationship between PPC after micro single-port VATS and perioperative indexes in patients with spontaneous pneumothorax. Clinically, targeted prevention and treatment can be implemented according to the age, pulmonary disease, preoperative albumin level, intraoperative blood loss, degree of pleural adhesion and pain grading 24 hours after surgery.
ABSTRACT
Objective@#To explore the correlation between blood pressure and urinary phthalandione, MMP, MEP, MnBP, MiBP, PAEs.@*Methods@#Three schools were selected from Shenzhen, China for the present study. A total of 765 firstgrade students of Han ethnicity were recruited voluntarily from the selected schools during September 2016 to June 2017. They were divided into normal blood pressure (BP) group (lower than P90 group) and high BP group (BP≥P90). Linear and Logistic regression models were used to analyze the relationships between blood pressure and urine phthalate metabolite levels.@*Results@#Urinary MMP and MnBP in students of high BP group were significantly higher than that of students in normal BP group(t=13.12, 3.97, P<0.05). Linear regression models showed that Z score increased when MMP and MnBP levels increased(P<0.05). Logistic regression model suggested that the risk of high BP increased with the increment of MMP level adjusting creatinine, sex, age and BMI(OR=1.47, P<0.05). There was no statistical significance in the differences after adjusting many factors including family income and education level of parents(P>0.05).@*Conclusion@#Urinary phthalate metabolite levels are positively associated with blood pressure in first-grade children.
ABSTRACT
Objective To investigate the effects of sequential pulmonary resuscitation maneuver (RM) with pulmonary protective ventilation on hemodynamics and arterial blood gas in patients with acute respiratory distress syndrome (ARDS) caused by severe chest trauma. Methods Ninety-six ARDS patients caused by severe chest trauma admitted to Dongguan People's Hospital from January 2017 to December 2018 were enrolled, and they were divided into a RM group and a mechanical ventilation group according to different ventilation modes, 48 cases being in each group. The mechanical ventilation group was given low tidal volume ventilation combined with the best positive end-expiratory pressure (PEEP); while the RM group was given sequential lung RM therapy on the basis of treatment in the mechanical ventilation group. The heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), cardiac output (CO), cardiac output index (CI), systemic circulation resistance index (SVRI) arterial blood gas were monitored before and after treatment in the two groups, and oxygenation index(PaO2/FiO2) was calculated; The mechanical ventilation time, intensive care unit (ICU) hospitalization time, incidence of ventilator associated pneumonia (VAP), mortality and incidence of adverse reaction were observed between the two groups. Results After treatment, the pH value and arterial partial pressure of carbon dioxide (PaCO2) of the two groups had no significant change; with the prolongation of treatment, the arterial partial pressure of oxygen (PaO2) and arterial blood oxygen saturation (SaO2);PaO2/FiO2 were increased significantly, total carbon dioxide (TCO2) was decreased significantly, after 72 hours of treatment, the degree of change in the RM group were more remarkable greater than those in the mechanical ventilation group [PaO2 (mmHg, 1 mmHg = 0.133 kPa): 91.02±9.03 vs. 80.34±7.66, SaO2: 0.96±0.04 vs. 0.94±0.04, TCO2 (mmol/L): 24.72±2.83 vs. 23.54±2.76, PaO2/FiO2 (mmHg): 238.47±19.83 vs. 185.34±17.37, all P < 0.05]. The ICU hospitalization time and mechanical ventilation time in the RM group were significantly lower than those in the mechanical ventilation group [ICU hospitalization time (days): 22.03±3.39 vs. 26.75±4.04,mechanical ventilation time (days): 13.38±4.04 vs. 19.33±5.02], and the incidence of VAP and mortality in the RM group were significantly lower than those in the mechanical ventilation group[incidence of VAP: 25.00% (12/48) vs. 8.33% (4/48), mortality: 18.75% (9/48) vs. 22.92% (11/48), both P < 0.05]. With the extension of time, CVP, MAP, CO, CI and SVRI in RM group all showed a trend of first decreasing and then increasing, while HR showed a trend of increasing and then decreasing, and the above indicators in 5 minutes after pulmonary re-opening, gradually returned to normal, showing no statistical significances compared with those before treatment [HR (bpm): 97.88±6.22 vs. 98.20±8.37, CVP (mmHg): 6.33±1.35 vs. 6.32±1.36, MAP (mmHg): 94.56±5.96 vs. 95.03±9.82, CO (L/min): 6.34±1.42 vs. 6.40±1.23, CI (L·min-1·s-1):2.08±0.32 vs. 2.17±0.53, SVRI: 2 404.34±31.34 vs. 2 474.34±29.73, all P > 0.05]. No adverse reactions occurred in the two groups. Conclusion Pulmonary protective ventilation sequential lung recruitment maneuver can significantly improve the oxygenation of ARDS caused by severe chest trauma, shorten the durations of mechanical ventilation and hospitalization in ICU, reduce the incidence of VAP, improve pulmonary inflammation, and in the mean time it has no serious adverse effects on hemodynamics.
