prone vs supine ventilation

The conclusions were not changed after adjustment for publication bias by using the trim and fill method (RR: 0.87; 95% CI: 0.75–1.00;  = 0.054; Figure 8) [34]. Several strengths of this study should be highlighted: (1) the selection and concerning confounder biases were lower because this analysis was based on RCTs; (2) this study utilized a large sample size, and the results are more robust than individual trials; and (3) stratified analyses based on patients’ characteristics were conducted, which allows us to obtain more exploratory results. [25] (Table 2). The risk of mortality in patients who received prone position ventilation was 13% lower than for those who received supine ventilation, but this effect was not statistically significant (RR: 0.87; 95% CI: 0.75–1.00;  = 0.055). The collected variables included: first author’s surname, publication year, country, sample size, mean age, percentage of male patients, mean partial pressure of arterial oxygen (PaO2), fractional concentration of inspired oxygen (FIO2), mean positive end-expiratory pressure (PEEP), mean FIO2, duration of ARDS, duration of prone positioning, protective lung ventilation, and reported outcomes. Publication bias for mortality was assessed by funnel plots, Egger’s test, and Begg’s test, and the results suggest potential publication bias for mortality ( value for Egger’s test: 0.076; value for Begg’s test: 0.276; Figure 7). Moreover, we noted that prone versus supine positioning was associated with lower risk of mortality when the mean age of the patients was <60.0 years, the percentage of male patients was <70.0%, or intervention was used as protective lung ventilation. The adverse events are also summarized between prone and supine positioning for ARDS patients. prone-positioning sessions of at least 16 hours duration (n=237) with the supine position (n=229) primary outcome: 28-day mortality lower in the prone group (16% versus 32.8%; P<0.001; hazard ratio for death 0.39, 95% CI 0.25 to 0.63) secondary outcomes: There was a significant improvement in oxygenation during prone positioning (PaO 2 /FiO 2 181 mm Hg in supine position vs. PaO 2 /FiO 2 286 mm Hg in prone position). PRONE positioning is a simple method to improve oxygenation in ventilated patients with acute respiratory distress syndrome (ARDS). The summary results indicate that prone versus supine positioning was not associated with risk of mortality, though this conclusion was not stable and could have been affected by two specific individual trials [22, 25]. There were no significant differences between prone and supine position ventilation on the duration of mechanical ventilation (WMD: −0.22;  = 0.883) or ICU stays (WMD: –0.39;  = 0.738). Featured in the book,”AACN Procedure Manual for High Acuity, Progressive, and Critical Care.7th ed. Sensitivity analysis indicated prone versus supine positioning might be associated with lower risk of mortality in ARDS patients when excluding the trial conducted by Gattinoni et al. The pooled results of this study indicate no significant differences between prone and supine positioning for mechanical ventilation duration and ICU stays. Moreover, there were no significant differences between prone and supine positioning for mechanical ventilation duration and ICU stays. Lung ventilation and perfusion in prone and supine postures with reference to anesthetized and mechanically ventilated healthy volunteers During mechanical ventilation, prone posture favors a more evenly distributed Q between lung regions. The results indicated that prone positioning during ventilation might have a beneficial effect on mortality, though incidence of several adverse events was significantly increased for these patients. [22] or Guérin et al. The Prone-Supine I Study9 was a multicenter, randomized trial, in patients aged 16 years or older with ALI or ARDS, of conventional treatment compared with placing patients (n 5 295) in a prone position for 6 or more hours daily for 10 days. Mechanical ventilation is widely used to improve oxygenation and reduce harmful effects in ARDS patients, though whether prone positioning during ventilation can improve clinical endpoints versus supine positioning remains unclear. The pooled effect estimates were calculated and applied to the random-effects model (the DerSimonian–Laird method) [14, 15]. Prone positioning is known to improve the PaO2/FiO2 ratio and reduce mortality in patients with ARDS managed in the critical care setting. We noted that prone positioning was associated with greater risk of pressure scores, displacement of a thoracotomy tube, and endotracheal tube obstruction. We identified all relevant trials using the following techniques: electronic searches of MEDLINE, EMBASE, and CENTRAL (from inception to November Prone versus supine position ventilation on the risk of mortality. STATA software was used for all of statistical analyses in this study (version 12.0, Stata Corporation, College Station, TX, USA). In the prone position, the lungs' dorsal aspects have less pleural pressure, which alleviates forces trying to collapse the alveoli. The Jadad scale scores ranged from 0 to 7; studies with a score ≥5 were defined as high quality. Published online first on August 3, 2020. METHODS—Ventilatory and arousal responses to mild asphyxia (hypercapnia/hypoxia) were measured in 53 healthy infants at newborn and 3 months of age, during quiet sleep (QS) and active sleep (AS), and in supine and prone sleep positions. We are committed to sharing findings related to COVID-19 as quickly as possible. Moreover, patients that received prone positioning could had increased risk of pressure ulcers and major airway problems [38]. ventilation in the prone compared with supine position in patients with ALI, ARDS, and acute hypoxemic respira-tory failure [28]. The risks of adverse events between prone and supine positioning are summarized in Table 4. The prone scan showed a partial recovery of the aerated lung parenchyma in the right inferior lobe with a small area of residual consolidation in the posterior segment of the right lower lobe. The numbers of studies available for mechanical ventilation duration and ICU stays were six (7 cohorts) and six (7 cohorts), respectively. The subgroup analyses for mortality were then performed according to sample size, mean age, percentage male, duration of intervention, protective lung ventilation, and study quality. The study conducted by Taccone et al. This study was performed in concordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Statement [12]. P:F ratio <150 2. ASA members enjoy complimentary access to ASA publications, as well as a variety of educational resources. No significant differences between prone and supine positioning were observed for the risks of displacement of tracheal tube (RR: 1.35; 95% CI: 0.47–3.84;  = 0.579), unplanned extubation (RR: 1.02; 95% CI: 0.73–1.43;  = 0.906), selective intubation (RR: 2.64; 95% CI: 0.26–26.73;  = 0.411), loss of venous access (RR: 1.52; 95% CI: 0.22–10.26;  = 0.669), hemoptysis (RR: 0.85; 95% CI: 0.35–2.05;  = 0.717), cardiac arrest (RR: 0.71; 95% CI: 0.40–1.26;  = 0.245), pneumothorax (RR: 0.86; 95% CI: 0.58–1.29;  = 0.471), and ventilator-associated pneumonia (RR: 1.34; 95% CI: 0.65–2.76;  = 0.427). ARDS patients that received prone position ventilation could experience increased risk of pressure scores, displacement of a thoracotomy tube, and endotracheal tube obstruction. Invasive mechanical ventilation is traditionally delivered with the patient in the supine position. Copyright © 2020, the American Society of Anesthesiologists, Inc. All Rights Reserved. PubMed, Embase, and the Cochrane Library were searched from their inception up to September 2020, and the following searching terms were combined by AND or OR: body posture, body position, prone position, prone positioning, ARDS, respiratory failure, and lung injury. However, these results were based on a smaller number of included trials, and this result needs to be verified by a large-scale RCT. However, several limitations should also be acknowledged: (1) substantial heterogeneity was detected for several outcomes, which could not be interpreted in subgroup analyses; (2) the analysis of this study was based on published articles, and unpublished data were not available; and (3) the background therapies for ARDS patients were not known, which also affect the prognosis of ARDS. ), Manuel Taboada, Anaberta Bermúdez, María Pérez, Olga Campaña; Supine versus Prone Positioning in COVID-19 Pneumonia: Comment. No significant differences between prone and supine positioning on mechanical ventilation duration (WMD: –0.22; 95% CI: –3.14 to 2.70;  = 0.883; Figure 3) or ICU stays (WMD: –0.39; 95% CI: –2.70 to 1.91;  = 0.738; Figure 4) were detected.

The usual practice is to position the newborn in supine (face-up) position during ventilation. A. Mora-Arteaga, O. J. Bernal-Ramírez, and S. J. Rodríguez, “The effects of prone position ventilation in patients with acute respiratory distress syndrome. Prone position (PP) has been used since the 1970s to treat severe hypoxemia in patients with ARDS.1-3 Mellins1 observed that in advanced cystic fibrosis, children spon-taneously position themselves on their hands and knees to improve ventilation. A meta-analysis conducted by Alsaghir and Martin contained five studies and found that prone positioning did not yield additional benefits with regard to mortality, whereas it improved oxygenation as compared with supine positioning. A study by Hu et al. The purpose of this meta-analysis was to compare the efficacy and safety of prone versus supine position ventilation for adult acute respiratory distress syndrome (ARDS) patients. Moreover, the risk of pressure scores, displacement of a thoracotomy tube, and endotracheal tube obstruction were significantly increased in ARDS patients received prone positioning. The mortality of severe ARDS exceeds 60%, although low-volume, low-pressure ventilation strategies have been employed to reduce ventilator-induced lung injury [5–8]. These conclusions are not stable and could be altered by excluding individual trials. No differences in mortality or complications were identified for the prone versus … This letter was sent to the author of the original article referenced above, who declined to respond.—Evan D. Kharasch, M.D., Ph.D., Editor-in-Chief, (Accepted for Publication July 15, 2020. Mora-Arteaga et al. Compared with the supine position (SP), placing patients in PP effects a more even tidal volume distribution, in part, by reversing the vertical pleural pressure gradient, which becomes more negative in the dorsal regions. “If the patient cannot tolerate the prone position, or has worsening hypoxia, work of breathing or tachycardia, the patient is returned to the supine position and their head-of-bed elevated. The remaining 28 studies were retrieved for full-text evaluation, and 12 RCTs were selected for final analyses [22–33]. Therefore, this meta-analysis, based on published RCTs, was carried out to evaluate the efficacy and safety of prone versus supine position ventilation in patients with ARDS. Results: We analyzed data for fifty-one patients with ARDS following abdominal surgery. These quantitative analyses contained 2264 adults with ARDS across a broad range of patient characteristics. However, the limitations of these studies included several other efficacy and safety outcomes were not calculated, or subgroup analyses for the risk of mortality according to other patients’ characteristics were not presented. involved 9 RCTs and found prone ventilation was associated with a reduced risk of mortality in patients with severe hypoxemia [6]. Minor reversible complications occurred in 6% of prone positioning cases. RCTs investigating the efficacy and safety of prone versus supine position ventilation in patients with ARDS were eligible for this meta-analysis. FiO2 >60% 4. Thus, a prone-to-supine change would be the opposite of what Lemaire and colleagues observed when removing positive pressure . A2017567) and 2020 Natural Science Foundation of Guangdong Province (grant no.2020A1515010383). Total duration of ARDS <36h The Jadad scale, taking into consideration randomization, blinding, allocation concealment, withdrawals and dropouts, and use of intention-to-treat analysis, was applied to assess the quality of included studies [13]. At this point, it’s likely that intubation and mechanical ventilation will be … Anesthesiology 2020; 133:1155–1157 doi: https://doi.org/10.1097/ALN.0000000000003511, PRONE positioning is a simple method to improve oxygenation in ventilated patients with acute respiratory distress syndrome (ARDS).1  Potential explanations are reduction of ventilation/perfusion mismatch, a more homogeneous distribution of transpulmonary pressure along the ventral-to-dorsal axis, and recruitment of nonaerated dorsal lung regions of the lung, with an increase in lung volume.2  Many of these mechanisms could also apply to awake patients with ARDS by COVID-19.3. The effects of prone versus supine position ventilation on the risk of mortality were reported in 11 RCTs. The differences between subgroups were assessed by using the interaction P test [19]. Two authors independently conducted the study selection, and any conflicts were settled by discussion until a consensus was reached. A funnel plot, Egger’s test, and Begg’s test were used to assess publication bias for mortality [20, 21]. Also, Patients were divided into a prone ventilation group and a supine ventilation group when the treatment for ARDS was started. Prone position ventilation has been adopted in ARDS patients in order to improve oxygenation and lung recruitment [9]. Table 1 summarizes the characteristics of the studies and patients. Uncertainty remains regarding the differences in efficacy and safety for prone versus supine positioning in ventilation of adults with ARDS. 5 Typically, patients remain supine during mechanical ventilation; however, prone positioning has been used for the treatment of ARDS since the 1970s. Treatment guidelines suggest maintaining oxygen saturation >90%; a ratio of PaO 2 to FiO 2 >200; a pH of 7.25–7.40, and a plateau pressure <35 cm H 2 O. identified 7 RCTs and found that prone position ventilation could decrease mortality risk for patients with low tidal volume, prolonged pronation, starting within the first 48 hours of disease evolution, and severe hypoxemia [39]. Sensitivity analyses for mortality, mechanical ventilation duration, and ICU stays were conducted to assess the robustness of pooled results [18]. A total of 363 studies were identified from the initial electronic database search, and 183 studies remained after removing duplicate publications. AIMS—To compare the effects of prone and supine sleep position on the main physiological responses to mild asphyxia: increase in ventilation and arousal. Finally, the treatment effectiveness of prone versus supine positioning on the risk of mortality could affect by percentage male, and whether used as protective lung ventilation. The relative risks (RRs) and weighted mean differences (WMDs) with corresponding 95% confidence intervals (CIs) were employed to calculate pooled outcomes using the random-effects models.
