Objective: To issue recommendations for reduced energy consumption in controlled environment zones (CEZ) in operating theaters and interventional sectors., Design: A committee bringing together seven experts from the SFAR, AFC, SF2H, ASPEC and SOFCOT was convened by CERES. A conflict-of-interest statement was developed at the beginning of the process and enforced throughout the elaboration of the reference document. The experts received no financing from any company commercializing a healthcare product (medicine or medical device). The committee was called upon to follow and respect the GRADE® (grading of recommendations assessment, development and evaluation) method to evaluate quality of the factual data on which the recommendations were based., Methods: We analyzed the relevant literature and formulated the recommendations in accordance with the GRADE® methodology by identifying three different fields. Each question was formulated in accordance with the PICO (patients, intervention, comparison, outcome) format., Results: The experts' attempts at synthesis and application of the GRADE® method led to 16 recommendations. In cases where GRADE® method could not be applied, the recommendations were formulated as expert advice., Conclusion: Once strong agreement among the experts had been reached, we formulated 15 recommendations for decreased energy consumption and reduced environmental impact in the controlled environment zones of operating theaters and interventional sectors., (Copyright © 2024 Elsevier Masson SAS.

Objective: To provide guidelines for reducing the environmental impact of general anaesthesia., Design: A committee of ten experts from SFAR and SF2H and SFPC learned societies was set up. A policy of declaration of competing interests was applied and observed throughout the guideline-writing process. Likewise, it did not benefit from any funding from a company marketing a health product (drug or medical device). The committee followed the GRADE® method (Grading of Recommendations Assessment, Development and Evaluation) to assess the quality of the evidence on which the recommendations were based., Methods: We aimed to formulate recommendations according to the GRADE® methodology for three different fields: anaesthesia vapours and gases; intravenous drugs; medical devices and the working environment. Each question was formulated according to the PICO format (Population, Intervention, Comparator, Outcome). The literature review and recommendations were formulated according to the GRADE® methodology., Results: The experts' work on the synthesis and application of the GRADE® method led to the formulation of 17 recommendations. Since the GRADE® method could not be entirely applied to all of the questions, some of the recommendations were formulated as expert opinions., Conclusion: Based on strong agreement between experts, we produced 17 recommendations designed to guide reducing the environmental impact of general anaesthesia., (Copyright © 2023 Société française d'anesthésie et de réanimation (Sfar).

Objective: To provide guidelines for the choice of items of clothing (except sterile surgical gown) for staff working in the operating theatre., Design: A committee of nine experts from SFAR and the SF2H learned societies was convened. A formal conflict-of-interest policy was developed at the beginning of the process and enforced throughout. Likewise, it did not benefit from any funding from a company marketing a health product (drug or medical device). The authors were required to follow the rules of the GRADE® method (Grading of Recommendations Assessment, Development and Evaluation) to assess the quality of the evidence on which the recommendations were based., Methods: We aimed to formulate recommendations according to the GRADE® methodology for four different fields: operating theatre suits, operating theatre hats, masks, and shoes/over-shoes. Each question was formulated according to the PICO format (Patient, Intervention, Comparison, Outcome). The literature review and recommendations were formulated according to the GRADE® methodology., Results: The experts' synthesis work and their application of the GRADE® method resulted in 13 recommendations. As the GRADE® method could not be integrally applied to all questions, some recommendations were formulated as expert opinions., Conclusion: Based on strong agreement between experts, we produced 13 recommendations to guide the choice of operating theatre attire., (Copyright © 2022 The Authors.

Background: Obstetric anaesthesia has been associated with concern for the inhalation of gastric contents for many years, justifying fasting during labour. However, many anaesthesiologists and obstetricians now allow fluid intake during labour., Objective(s): We hypothesised that allowing oral fluid intake during labour is not associated with increased gastric contents. We used ultrasound assessment of gastric contents to evaluate this hypothesis., Design: A randomised, single-blind and intention-to-treat noninferiority trial comparing antral area measured by ultrasound in fasting parturients and in those who were allowed to drink fluid for 90 min after randomisation., Setting: Tenon University Hospital, Assistance Publique Hôpitaux de Paris, Paris, France., Patients: Pregnant women, aged from 18 to 40 years and from week 36 of an uncomplicated singleton gestation, were randomised into a fasting group and a fluid intake group after admission to the delivery room. Of the 184 patients screened, data from 125 were analysed: fasting group (62), fluid intake group (63)., Intervention: Women in the fluid intake group were allowed to drink up to 400 ml of apple juice for 90 min after randomisation., Main Outcome Measure: We compared the percentage of women with an 'empty stomach' between the two groups: empty stomach was defined as an antral cross-sectional area (CSA) less than 300 mm assessed in a semirecumbent position with a 45-degree head-up tilt., Results: At full cervical dilatation an antral CSA less than 300 mm was measured in 76 and 79% of the parturients in the fasting group and the fluid intake groups respectively (P = 0.633)., Conclusion: The current study reveals that the percentage of pregnant women with an 'empty stomach', defined by an antral CSA less than 300 mm in a semirecumbent position with a 45-degree head-up tilt, was comparable at full cervical dilation among those who remained nil by mouth and those allowed to drink up to 400 ml for 90 min after their randomisation., Trial Registration: Clinicaltrials.gov identifier: NCT02362815.

Background: Acute chest syndrome (ACS) is the main cause of morbi-mortality in patients with sickle-cell disease in the intensive care unit (ICU). ACS definition encompasses many types of lung damage, making early detection of the most severe forms challenging. We aimed to describe ACS-related lung ultrasound (LU) patterns and determine LU performance to assess ACS outcome., Results: We performed a prospective cohort study including 56 ICU patients hospitalized for ACS in a tertiary university hospital (Paris, France). LU and bedside spirometry were performed at admission (D0) and after 48 h (D2). Complicated outcome was defined by the need for transfusion of ≥ 3 red blood cell units, mechanical ventilation, ICU length-of-stay > 5 days, or death. A severe loss of lung aeration was observed in all patients, predominantly in inferior lobes, and was associated with decreased vital capacity (22 [15-33]% of predicted). The LU Score was 24 [20-28] on D0 and 20 [15-24] on D2. Twenty-five percent of patients (14/56) had a complicated outcome. Neither oxygen supply, pain score, haemoglobin, LDH and bilirubin values at D0; nor their change at D2, differed regarding patient outcome. Conversely, LU re-aeration score and spirometry change at D2 improved significantly more in patients with a favourable outcome. A negative LU re-aeration score at D2 was an independent marker of severity of ACS in ICU., Conclusions: ACS is associated with severe loss of lung aeration, whose resolution is associated with favourable outcome. Serial bedside LU may accurately and early identify ACS patients at risk of complicated outcome.

Background: There is no defined gold standard for pain management after video-assisted thoracic surgery (VATS) for pneumothorax. In addition to systemic analgesia, various loco-regional analgesic techniques have been proposed but remain poorly evaluated in this context. We aimed to assess the analgesic efficacy of several of these techniques for the management of postoperative pain., Methods: We conducted a monocentric prospective observational cohort study from February 2017 to April 2018 in patients suffering from spontaneous pneumothorax and scheduled for VATS (n = 59). Patients received systemic analgesia (i) alone (n = 15); (ii) combined with a continuous paravertebral block (n = 9); (iii) combined with a continuous serratus plane block (n = 19); or (iv) single-shot serratus plane block (n = 16) as decided by the attending physician. Pain scores and analgesic-related side effects were prospectively collected by an independent observer during the first postoperative 72 h. The primary endpoint criterion was the cumulative oral morphine consumption at the end of the third postoperative day. Statistical analysis used univariate and multivariate step-by-step forward logistic regression models to determine risk factors associated with the main criteria., Results: Mean pain scores and morphine consumption were not significantly different between the 4 groups. In the multivariate analysis, the use of a continuous serratus plane block through a catheter was the only technique associated with a reduced incidence of high-dose oral morphine consumption (OR 0.09-95%CI [0.01-0.79], p = 0.03)., Conclusion: This study suggests that serratus plane block combined with continuous infusion through a catheter may have some benefits, although further studies are needed to confirm these results and determine the true place of the serratus plane block in pain management after VATS for pneumothorax.

Plastic bronchitis is used to designate endobronchial plugs of rubber-like consistency that form into bronchial trees. It has been described in several diseases like asthma, cystic fibrosis, pulmonary infection, cyanotic congenital heart disease and in few young children with homozygous sickle cell disease. We report the first sickle cell adult case of plastic bronchitis during acute chest syndrome. He developed severe acute respiratory distress syndrome. This unusual presentation related to obstruction by voluminous casts may alert physicians to focus more on the bronchi in sickle cell patients. Realization of fiberoptic bronchoscopy to diagnose endobronchial injury and preventive measures such as fluidification of sputum at the early stage of thoracic vaso-occlusive crisis are essential.
