Objective To explore the efficacy of prone positioning ventilation in patients with acute respiratory distress syndrome (ARDS) after acute Stanford type A aortic dissection (STAAD) surgery. Methods From November 2019 to September 2021, patients with ARDS who was placed prone position after STAAD surgery in the Xiamen Cardiovascular Hospital of Xiamen University were collected. Data such as the changes of blood gas, respiratory mechanics and hemodynamic indexes before and after prone positioning, complications and prognosis were collected for statistical analysis. ResultsA total of 264 STAAD patients had surgical treatment, of whom 40 patients with postoperative ARDS were placed prone position. There were 37 males and 3 females with an average age of 49.88±11.46 years. The oxygen partial pressure, oxygenation index and peripheral blood oxygen saturation 4 hours and 12 hours after the prone positioning, and 2 hours and 6 hours after the end of the prone positioning were significantly improved compared with those before prone positioning ventilation (P<0.05). The oxygenation index 2 hours after the end of prone positioning which was less than 131.42 mm Hg, indicated that the patient might need ventilation two or more times of prone position. Conclusion Prone position ventilation for patients with moderate to severe ARDS after STAAD surgery is a safe and effective way to improve the oxygenation.
Objective To investigate the current status and influencing factors of the awake prone position in patients with mild and moderate acute respiratory distress syndrome (ARDS). Methods A total of 210 patients with mild to moderate ARDS admitted between December 2022 and January 2023 were investigated by general information questionnaire and self-made prone position knowledge questionnaire. The daily prone position time during hospitalization was recorded. The influencing factors of awake prone position were analyzed by univariate and multivariate linear regression. Results The 210 mild and moderate ARDS patients had an average daily prone position length of stay of (4.97±3.94)h/d, showing a low level. Multiple linear regression analysis showed that prone position knowledge score, age, waist circumference and BMI were the influencing factors of awake prone position (P<0.05). Conclusions Daily awake prone position length was at a low level in mild and moderate ARDS patients. Healthcare workers can prolong the time in the prone position by developing an individualized treatment plan for the prone position, improving the patient’s perception of the prone position, and resolving the discomfort from the prone position.
ObjectiveTo compare the short-and mid-term outcomes of patients with esophageal cancer after subtotal esophagectomy via thoracoscopy in lateral prone position, prone position, or left lateral position. MethodsThis randomized prospectively controlled study was conducted in 121 patients receiving subtotal esophagectomy via thoracoscopy between January 2010 and February 2013. The patients were randomly assigned into three groups to underwent esophagectomy in lateral prone position, prone position, or left lateral position, respectively. Forty-three patients (24 males, 19 females, 61.5±1.5 years) underwent surgery in lateral prone position, 39 patients (21 males, 18 females, 63.2±1.7 years) in prone position and other 39 patients (22 males, 17 females, 60.1±1.6 years) in left lateral position. Esophagogastric anastomosis was performed in the left neck. ResultsThe median operative time in the three groups was 232 (165-296) min, 230 (170-310) min, and 280 (190-380) min, respectively (P < 0.05). The median perioperative bleeding was 262 (185-330) ml, 275 (100-320) ml and 350 (120-560) ml, respectively (P > 0.05). The average number of harvested lymph nodes was 19.1 (9-26), 18.4 (11-23), 10.9 (6-21), respectively (P < 0.05). The postoperative medical complications occurred in 10, 9 and 11 patients in three groups, respectively, with no statistical difference. Twenty patients died in the lateral prone position group after a median follow-up period of 19.2 (6-31) months, 18 patients died in the prone position group after a median follow-up period of 20.7 (8-29) months, and 21 patients died in the left lateral position group after a median follow-up period of 18.5 (12-33) months. ConclusionThe results confirm the feasibility and safety of this minimally invasive esophagectomy via thoracoscopy in lateral prone position, prone position, or left lateral position for patients with esophageal carcinoma. A possible advantage of lateral prone technique is that in case of an emergency, precious time could be saved in changing the position of the patient.
Objective To investigate the early motor development and the risk factors affecting motor development in children with congenital muscular torticollis (CMT) aged 0–3 months. Methods CMT infants admitting to the Department of Rehabilitation Medicine, Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine between January 1st, 2016 and April 30th, 2018 were enrolled as CMT group, and contemporaneous age-matched healthy infants were enrolled as the control group. Motor development was assessed with the Alberta Infant Motor scale (AIMS). We collected the birth weight, birth length, mode of birth, sleep position, and prone time when awake as dependent variables, and used multiple linear regression to find the variables that had significant effect on AIMS scores. Results There were 97 CMT infants (62 males and 35 females) with the mean age of (46.8±17.3) days, mean birth weight of (3.34±0.38) kg and mean birth length of (49.56±0.93) cm in the CMT group, while there were 97 healthy infants (60 males and 37 females) with the mean age of (45.1±19.4) days, mean birth weight of (3.38±0.35) kg and mean birth length of (49.84±1.03) cm in the control group, and the differences in sex, age, birth weight, birth length between the two groups were not statistically significant (P>0.05). AIMS centiles showed that 36 infants (37.1%) in CMT group had suspicious or abnormal motor development, while only 12 infants (12.4%) in the control group had; there was a significant statistical difference between the two groups (χ2=15.945, P<0.001). Multiple linear regression analysis showed that the time of prone position when awake and CMT had significant influence on the AIMS scores (F=64.851, P<0.001). Infants who had a long prone position when awake had significantly higher AIMS scores and CMT had a significantly lower AIMS scores (P<0.001). Conclusions The risk of early motor retardation in infants with CMT aged 0–3 months is higher than that in healthy infants of the same age. The decrease in prone position when awake and CMT may be the causes of delayed motor development. Clinical medical personnel and family caregivers should pay more attention to motor development and provide reasonable intervention to CMT infants.
ObjectiveTo evaluate the full thickness idiopathic macular hole (IMH) closure rates in patients positioning non-supine (NSP) compared with patients positioning face-down (FDP). MethodsA computerized search was conducted in the PubMed, Chinese Biomedical Database, China National Knowledge Infrastructure, and VIP database. All the included studies were divided into NSP and FDP group. A total of 9 papers were included in this meta analysis, including 285 eyes (145 eyes with small hole ≤400 μm, 104 eyes with large hole >400 μm) in NSP group and 303 eyes (141 eyes with small hole and 124 eyes with large hole ). RevMan 4.2 software was applied for investigating heterogeneity and meta-analysis, and the risk of publication bias was evaluated. ResultsMeta analysis indicated that there was statistical significance on closure rates betwen NSP and FDP group. The difference of closure rates in small macular hole eyes between NSP and FDP group was statistically significant (OR=0.45, 95%CI 0.13-1.51;P=0.20). The difference of closure rates in large macular hole eyes between NSP and FDP group was statistically significant (OR=0.35, 95%CI 0.17-0.75;P=0.006). ConclusionNSP is equally effective as strict FDP in the repair of small macular hole. Post-operative FDP may improve the macular hole closure rates for holes larger than 400 μm.
Objective To formulate an evidence-based position program for a ventilation patient with acute respiratory distress syndrome (ARDS). Methods Based on fully assessing the patient’s conditions, the clinical problems were put forward according to PICO principles. Such database as The Cochrane Library (2005 to January 2011), DARE (March 2011), CCTR (March 2011), MEDLINE (1996 to January 2011) and CNKI (1979 to January 2011) were retrieved to collect high quality clinical evidence, and then the optimum nursing program was designed in line with patient’s conditions and relatives’ willingness. Results Three meta-analyses, three randomized controlled trials, one systematic review and one anterior-posterior self-control study were included. The available clinical evidence displayed that: a) the prone position adopting earlier, especially for patients with bilateral lungs or left lung functional disorder, was propitious to effectively improve the oxygenation condition and reduce the incidence of ventilator induced lung injury (VILI); b) The long-term prone position could increase the risk of pressure sore; c) The prone position could prolong the survival time, but there was no enough evidence to prove that it could obviously decrease the mortality rate of ARDS. So finally a nursing plan was made in combination with literature evidence and patient’s condition: adopting the prone position after onset within 24 to 36 hours, and enhancing the skin nursing to prevent pressure sore at the same time. After 4-week comprehensive therapy and prone position ventilation, the patient got obvious alleviated in oxygenation, with SpO 2 up to 90% to 100%, stable vital signs, and no more VILI and pressure sore. And then the patient was stopped applying ventilator, and transferred to a general ward for further treatment. Conclusion The earlier adoption of prone position ventilation for severe ARDS can improve oxygenation and reduce ventilator associated pneumonia (VAP) and VILI, but whether it can prolong survival time and reduce mortality for mild ARDS or not still has to be proved with more high quality evidence in the future.
ObjectiveTo evaluate the effect of prone position ventilation on mortality in ARDS patients by cumulative meta-analysis.MethodsDatabases including PubMed, EMbase, Web of Science, The Cochrane Library, CBM, CNKI, VIP, WanFang Data were searched from inception to September 30th, 2016 to collect randomized controlled trials (RCTs) about prone position ventilation in ARDS patients. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. In accordance with the published literature or published in chronological order, cumulative meta-analysis was performed using Stata12.0 software, and the trial sequencing analysis (TSA) method was used to assess the reliability and authenticity of the results.ResultsA total of 9 RCTs involving 2 359 patients were included. The cumulative meta-analysis results showed that the prone position ventilation could reduce the mortality in ARDS patients (OR=0.60, 95%CI 0.40 to 0.90). The TSA results showed that the definite conclusion had been obtained before the desired amount of information had been reached.ConclusionThe current evidence shows that prone position ventilation is associated with decreased mortality in ARDS patients. Due to limited quality and quantity of included studies, the above results are needed to validate by more studies.
