ObjectiveTo investigate the effect of positive family behavior support on emotional and behavioral problems in preschool children with epilepsy. Methods A total of 80 preschool epileptic children and their parents who were admitted to the Department of Neurology of our hospital from October 2022 to February 2023 were selected as the research objects, and were divided into experimental group and control group with 40 cases each by random number table method. The control group received neurology routine nursing, and the experimental group received positive family behavior support intervention based on the control group. The scores of family intimacy and adaptability scale, strengths and difficulties questionnaire, medication compliance and quality of life of epilepsy children were compared before and after intervention between the two groups. ResultsAfter intervention, the scores of strength and difficulty questionnaire in experimental group were lower than those in control group (P<0.05), and the scores of family intimacy and adaptability scale, quality of life and medication compliance in experimental group were higher than those in control group (all P<0.05). ConclusionThe application of positive family behavior support program can reduce the occurrence of emotional behavior problems, improve family closeness and adaptability, improve medication compliance, and improve the quality of life of preschool children with epilepsy.
Objective
To study the influence of low-tidal volume and positive end expiratory pressure (PEEP) protective ventilation on cardiac output volume in elderly patients under general anesthesia.
Methods
From August 2012 to July 2014, 60 elderly patients undergoing selective surgery were divided into three groups with 20 patients in each. Group A was treated with conventional ventilation: tidal volume at 8 mL/kg, PEEP at 0 cm H2O (1 cm H2O=0.098 kPa); group B was treated with a tidal volume of 6 mL/kg and a PEEP of 5 cm H2O; group C was treated with a tidal volume of 6 mL/kg and a PEEP of 8 cm H2O. We then observed and analyzed the blood pressure, heart rate, cardiac output, arterial blood gas and airway mean pressure before induction of anesthesia (T0), 15 minutes of mechanical ventilation after the induction of anesthesia (T1), 60 minutes after anesthesia induction (T2), and 15 minutes after tracheal extubation (T3).
Results
In all the three groups, the mean arterial pressure and cardiac output were stable. In group B and C, central venous pressure increased significantly, the mean airway pressure and lung compliance increased, and the arterial oxygen branch pressure also increased significantly (P < 0.05).
Conclusion
Low-tidal volume combined with 5-cm H2O or 8-cm H2O positive end expiratory pressure lung-protective ventilation had a small influence on the cardiac output of elderly patients under anesthesia, which can be safely used.
ObjectiveTo evaluate the correlation between positive end-expiratory pressure (PEEP) level and postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung surgery. MethodsThe clinical data of patients who underwent elective thoracoscopic lung surgery at West China Hospital of Sichuan University from January 2022 to June 2023 were retrospectively analyzed. Patients were divided into 2 groups according to intraoperative PEEP levels: a PEEP 5 cm H2O group and a PEEP 10 cm H2O group. The incidence of PPCs in the two groups after matching was compared using a nearest neighbor matching method with a ratio of 1∶1, setting the clamp value as 0.02. ResultsA total of 538 patients were screened, and after propensity score-matching, a total of 229 pairs (458 patients) were matched, with an average age of 53.9 years and 69.4% (318/458) females. A total of 118 (25.8%) patients had PPCs during hospitalization after surgery, including 60 (26.2%) patients in the PEEP 5 cm H2O group and 58 (25.3%) patients in the PEEP 10 cm H2O group, with no statistically significant difference between the two groups [OR=0.997, 95%CI (0.495, 1.926), P=0.915]. Multivariate logistic regression analysis showed that PEEP was not an independent risk factor for PPCs [OR=0.920, 95%CI (0.587, 1.441), P=0.715]. ConclusionFor patients undergoing thoracoscopic lung surgery, intraoperative PEEP (5 cm H2O or 10 cm H2O) is not associated with the risk of PPCs during hospitalization after surgery, which needs to be further verified by prospective, large-sample randomized controlled studies.
Objective To investigate whether pulse pressure variation( ΔPP) reflect the effects of PEEP and fluid resuscitation ( FR) on hemodynamic effects. Methods Twenty critical patients with acute lung injury was ventilated with volume control ( VT =8 mL/kg, Ti/Te = 1∶2) , and PaCO2 was kept at 35 to 45 mm Hg. PEEP was setted as 5 cm H2O and 15 cmH2O in randomized order. Hemodynamic parameters including cardiac index, pulse pressure, central venous pressure, etc. were monitered by PiCCO system.Measurements were performed after the application of 5 cmH2O PEEP ( PEEP5 group) and 15 cm H2OPEEP ( PEEP15 group) respectively. When the PEEP-induced decrease in cardiac index ( CI) was gt; 10% ,measurements were also performed after fluid resuscitation. Results Compared with PEEP5 group, CI was decreased significantly in PEEP15 group( P lt;0. 05) , and ΔPP was increased significantly( P lt; 0. 05) . In 14 patients whose PEEP-induced decrease in CI was gt; 10% , fluid resuscitation increased CI from ( 3. 01 ±0. 57) L·min - 1·m- 2 to ( 3. 62 ±0. 68) L·min- 1 ·m- 2 ( P lt;0. 01) , and decreased ΔPP from ( 17 ±3) % to ( 10 ±2) % ( P lt;0. 01) . PEEP15 -induced decrease in CI was correlated negatively with ΔPP on PEEP5 ( r= - 0.91, P lt;0. 01) and with the PEEP15 -induced increase in ΔPP ( r = - 0. 79, P lt;0. 01) . FR-induced changes in CI correlated with ΔPP before FR ( r =0. 96, P lt; 0. 01) and with the FR-induced decrease in ΔPP ( r= - 0. 95, P lt; 0. 01) . Conclusions In ventilated patients with ALI, ΔPP may be a simple anduseful parameter in predicting and assessing the hemodynamic effects of PEEP and FR.
Simulation of the human biological lung is a crucial method for medical professionals to learn and practice the use of new pulmonary interventional diagnostic and therapeutic devices. The study on ventilation effects of the simulation under positive pressure ventilation mode provide valuable guidance for clinical ventilation treatment. This study focused on establishing an electrical simulation ventilation model, which aims to address the complexities in parameter configuration and slow display of air pressure and airflow waveforms in simulating the human biological lung under positive pressure ventilation mode. A simulated ventilation experiment was conducted under pressure-regulated volume control (PRVC) positive pressure ventilation mode, and the resulting ventilation waveform was compared with that of normal adults. The experimental findings indicated that the average error of the main reference index moisture value was 9.8% under PRVC positive pressure ventilation mode, effectively simulating the ventilatory effect observed in normal adults. So the established electrical simulation ventilation model is feasible, and provides a foundation for further research on the simulation of human biological lung positive pressure ventilation experimental platform.
ObjectiveTo explore whether positive end-expiratiory pressure (PEEP) guided by the esophageal balloon manometry is better than the ARDS Network standard of care recommendations during treating traumatic acute respiratory distress syndrome (ARDS) patients with mechanical ventilation.
MethodsTwelve traumatic ARDS patients selected from September 2013 to March 2015 in ICU of Xiamen No. 3 Hospital were administrated esophageal balloor catheter and underwent mechanical ventilation with PEEP adjusted according to measurements of esophageal pressure and the ARDS Network standard of care recommendations simultaneously. According to the selection method of PEEP, the patients were divided into two groups:the esophageal pressure guided group and the ARDS Network recommendations guided group (the control group). The changes of peak inspiratory pressure, esophageal pressure, transpulmonary end-expiratory pressure, transpulmonary end-inpiratory pressure, lung compliance at 0 h, 24 h, 48 h, 72 h following different PEEP treatments were observed and compared between two groups of patients.
ResultsA mean PEEP in the esophageal pressure guided group of (10.98±4.36)cm H2O was significantly higher than the control group of (7.13±2.21)cm H2O (P<0.01). The transpulmonary end-expiratory pressure was significantly higher in the esophageal pressure guided group (0.71±0.62)cm H2O than the control group (-2.29±3.49) cm H2O. And all of the mean transpulmonary end-expiratory pressure remained above zero in the esophageal pressure guided group, whereas in the control group 73% patients remained negative (P<0.01).
ConclusionsEsophageal pressure method adjusts PEEP for traumatic ARDS patients with mechanical ventilation through estimating pleural pressure so as to calculate transpulmonary pressure. It can identify traumatic ARDS patients who would benefit from the high PEEP, adjust PEEP individually and meet patients' need more satisfactorily.
Objctive
To explore the effect of positive lymph nodes ratio (LNR) on prognosis of patients with non-small cell lung cancer (NSCLC).
Methods
Clinical data of 432 NSCLC patients undergoing radical surgery for lung cancer and systemic lymph node dissection in our hospital from January 2010-2013 were retrospectively analyzed. There were 316 males and 116 females with age of 39-84 (57.59±9.16) years. Among 432 patients, 229 (53.0%) were classified as N0 based on pathological staging of lymph nodes, 104 (24.1%) as N1 and 99 (22.9%) as N2. Kaplan-Meier curve and COX multi-factor regression model were used to evaluate the correlation between the clinical data and patients' survival.
Results
Five lymph nodes on average (range, 1-52) were removed in each patient. Kaplan-Meier survival curves showed that the higher the staging of positive lymph nodes was, the shorter the patients' overall survival and disease-free survival were (P<0.001). Survival analysis showed that the LNR was closely associated with disease-free survival and overall survival (P<0.001). COX multivariate analysis revealed that the LNR staging was an independent risk factor of prognosis of NSCLC.
Conclusion
LNR is an independent prognostic factor of NSCLC, and can be used to improve lymph node staging in standards for NSCLC staging in the future.
ObjectiveTo investigate the blood pressure level and prevalence of hypertension in middle-aged people with positive family history of hypertension in Chengdu area, compare the differences between middle-aged people with positive family history of hypertension and middle-aged people with negative family history of hypertension, and explore the influencing factors of hypertension in middle-aged people with positive family history of hypertension.MethodsFrom September 2013 to March 2014, the stratified sampling method was used to survey 3 096 middle-aged people aged 40-59 years in Chengdu. Their height, weight, blood pressure, blood glucose, and blood lipids were measured. Questionnaire surveys were conducted using a uniformly designed questionnaire. The blood pressure levels and hypertension prevalences were compared between people with and without positive family history of hypertension. The influencing factors of hypertension in middle-aged people with positive family history of hypertension were analyzed using multiple logistic regression.ResultsThere were significant differences between the middle-aged people with positive family history of hypertension and the ones with negative family history of hypertension in systolic blood pressure [(137.4±22.4) vs. (118.0±11.3) mm Hg (1 mm Hg=0.133 kPa), P<0.001], diastolic blood pressure [(84.1±12.2) vs. (73.9±7.7) mm Hg, P<0.001], and prevalence of hypertension (28.6% vs. 22.2%, P<0.001). Ageing [odds ratio (OR)=1.107, 95% confidence interval (CI) (1.071, 1.144), P<0.001], monthly personal income ≥3 000 yuan [OR=1.566, 95%CI (1.003, 2.445), P=0.048], and abdominal obesity [OR=1.658, 95%CI (1.091, 2.520), P=0.018] were the risk factors for hypertension in middle-aged males with positive family history. Ageing [OR=2.257, 95%CI (1.202, 4.025), P=0.026] and overweight or obesity [OR=2.365, 95%CI (1.653, 3.385), P<0.001] were the risk factors, and physical exercise [OR=0.529, 95%CI (0.304, 0.918), P=0.024] was the protective factor for hypertension in middle-aged females with positive family history.ConclusionsThe prevalence of hypertension is high in middle-aged population with positive family history of hypertension in Chengdu and is significantly higher than that in the ones with negative family history of hypertension. Strengthening health education on hypertension-related knowledge, and reasonably controlling waist circumference and body weight may have positive significance in preventing or delaying the occurrence of hypertension in people with positive family history of hypertension.
ObjectiveTo evaluate the effect of driving pressure-guided lung protective ventilation strategy on lung function in adult patients under elective cardiac surgery with cardiopulmonary bypass.MethodsIn this randomized controlled trial, 106 patients scheduled for elective valve surgery via median sternal incision under cardiopulmonary bypass from July to October 2020 at West China Hospital of Sichuan University were included in final analysis. Patients were divided into two groups randomly. Both groups received volume-controlled ventilation. A protective ventilation group (a control group, n=53) underwent traditional lung protective ventilation strategy with positive end-expiratory pressure (PEEP) of 5 cm H2O and received conventional protective ventilation with tidal volume of 7 mL/kg of predicted body weight and PEEP of 5 cm H2O, and recruitment maneuver. An individualized PEEP group (a driving pressure group, n=53) received the same tidal volume and recruitment, but with individualized PEEP which produced the lowest driving pressure. The primary outcome was oxygen index (OI) after ICU admission in 30 minutes, and the secondary outcomes were the incidence of OI below 300 mm Hg, the severity of OI descending scale (the Berlin definition), the incidence of pulmonary complications at 7 days after surgery and surgeons’ satisfaction on ventilation.ResultsThere was a statistical difference in OI after ICU admission in 30 minutes between the two groups (273.5±75.5 mm Hg vs. 358.0±65.3 mm Hg, P=0.00). The driving pressure group had lower incidence of postoperative OI<300 mm Hg (16.9% vs. 49.0%, OR=0.21, 95%CI 0.08-0.52, P=0.00) and less severity of OI classification than the control group (P=0.00). The incidence of pulmonary complications at 7 days after surgery was comparable between the driving pressure group and the control group (28.3% vs. 33.9%, OR=0.76, 95%CI 0.33-1.75, P=0.48). The atelectasis rate was lower in the driving pressure group (1.0% vs. 15.0%, OR=0.10, 95%CI 0.01-0.89, P=0.01).ConclusionApplication of driving pressure-guided ventilation is associated with a higher OI and less lung injury after ICU admission compared with the conventional protective ventilation in patients having valve surgery.
Objective To explore the positive rate of scanning laser ophthalmoscope in the retromode (RM-SLO) in different types of diabetic macular edema (DME), and to analyze its correlation with foveal thickness (CMT) and macular volume. MethodsFrom March to May 2021, 40 patients (65 eyes) were diagnosed as DME by fundus examination combined with optical coherence tomography (OCT) in Affiliated Eye Hospital of Wenzhou Medical University at Hangzhou were included in the study. All eyes underwent best corrected visual acuity (BCVA), OCT and RM-SLO fundus imaging examinations, 47 eyes underwent fluorescein fundus angiography (FFA) examination. RM-SLO fundus imaging examinations were performed with Mirante SLO, including retro mode illumination deviated right (RMDR) and retro mode illumination deviated left (RMDL). If one or more of the RMDR and RMDL of the examined patient can identify macular edema, RM-SLO was considered to be able to identify macular edema. The macular volume at CMT and 6 mm from the fovea was measured by OCT software. DME were divided into 3 types based on OCT images: diffuse retinal thinkening (DRT) type; cystoid macular edema(CME) type; serous retinal detachment (SRD) type, focal leakage type, diffuse leakage type and diffuse cystic leakage type. The consistency of RMDR and RMDL in the diagnosis of DME in RM-SLO fundus imaging was evaluated, as well as their positive rate in different classifications of DME. The correlation between the detection of macular edema by RM-SLO and the DME type, CMT and foveal volume, and the correlation between BCVA and edema type, CMT and macular volume were analyzed. ResultsAmong 65 eyes, the positive rates of RMDR and RMDL fundus imaging to detect DME were 46 (70.77%, 46/65) and 48 (73.85%, 48/65), respectively. There was good consistency in identifying DME (Kappa value=0.770; P＜0.001). The positive rates of RMDR and RMDL fundus imaging DRT, CME and SRD type of DME were 42.11% (8/19), 57.89% (11/19), 77.78% (28/36), 77.78% (28/36), 100.00% (10/10), 90.00% (9/10), respectively. In the FFA classification of them, the positive rates of focal leakage, diffuse leakage and diffuse cystic leakage were 68.75% (11/16), 62.50% (10/16), 68.00% (17/25), 76.00% (19/25), 100.00% (6/6), 100.00% (6/6), respectively. The results of Spearman correlation analysis showed that whether RM-SLO could identify DME was associated with CMT and OCT classification (r=0.310, 0.365; P=0.120, 0.003); there was no correlation between FFA classification and macular volume (r=0.113, 0.117; P=0.449, 0.352). BCVA was correlated with CMT and macular volume (r=0.307, 0.269; P=0.013, 0.030), however, there was no significant correlation with OCT type, angiographic type (r=0.051, 0.175; P=0.684, 0.240). ConclusionThe diagnostic agreement of DME are good between RMDR, RMDL of RM-SLO image. DME of DRT type and patients with smaller CMT in OCT are difficult to identified by RM-SLO fundus imaging.
