[A preliminary study on the evaluation of diaphragm function by ultrasound in patients with invasive mechanical ventilation].
Objectives: To study the feasibility of using ultrasound to evaluate diaphragm function in patients with invasive mechanical ventilation. Methods: From March to December 2017, 40 adult patients with acute respiratory distress syndrome who were admitted to the Department of Critical Care Medicine, Xiangya Hospital, Central South University for more than 48 hours were included. Diaphragmatic excursion and thickness of bilateral anterior, middle and posterior parts were measured by ultrasound for 5 consecutive days. ⋯ Bilateral anterior, middle and posterior diaphragmatic excursion recovered on day 5, and was higher than the baseline levels on day 1, with the left middle and posterior diaphragmatic excursion changing most significantly. (2) Compared with day 1, 2, 3, the thickening fraction of bilateral anterior, middle and posterior diaphragm were significantly decreased on day 4, with the left middle part [day 1: (33.87±14.34)%; day 2: (37.26±13.91)%; day 3: (30.56±14.27)%; day 4: (15.53±5.68)%] and the left posterior part [day 1: (35.50±15.69)%; day 2: (39.84±15.32)%; day 3: (29.06±14.96)%; day 4: (13.30±5.79)%] changing most significantly (P<0.05). The thickening fractions of left anterior, middle and posterior diaphragm recovered on day 5 compared with that on day 4, but still lower than those on day 1 (P<0.05). Conclusions: It is feasible to evaluate the diaphragm function in patients with invasive mechanical ventilation by ultrasound, which can provide guidance for preventing diaphragmatic atrophy and withdrawing from mechanical ventilation.

Intra-abdominal compartment syndrome (ACS) is a devastating complication in burn patients with a high mortality. Apart from high-volume resuscitation as known risk factor, also mechanical ventilation seems to influence the development of ACS. The TIRIFIC trial is a retrospective, matched-pair analysis. ⋯ The TIRIFIC trial showed significantly increased ventilation pressures in the ACS group in general as a surrogate parameter to support early diagnostics. Especially, maximum PEEP levels and peak pressures are significantly increased in both, early- and late-onset ACS. As an addition to the actual WSACS guidelines we suggest IAP measurement in mechanically ventilated burn patients if ventilating pressures are rising continuously without a clear pulmonary or otherwise identifiable reason.

Randomized Controlled Trial Multicenter Study
Individualized PEEP to optimise respiratory mechanics during abdominal surgery: a pilot randomised controlled trial.
Higher intraoperative driving pressures (ΔP) are associated with increased postoperative pulmonary complications (PPC). We hypothesised that dynamic adjustment of PEEP throughout abdominal surgery reduces ΔP, maintains positive end-expiratory transpulmonary pressures (Ptp_ee) and increases respiratory system static compliance (Crs) with PEEP levels that are variable between and within patients. ⋯ NCT02671721.

Meta AnalysisTocilizumab for severe COVID-19: a systematic review and meta-analysis.
This systemic review and meta-analysis aimed to assess the efficacy of tocilizumab for the treatment of severe coronavirus disease 2019 (COVID-19). Candidate studies up to 24 May 2020 were identified from PubMed, Cochrane Library, Embase, medRxiv and bioRxiv. Treatment outcomes included mortality, risk of intensive care unit (ICU) admission and the requirement for mechanical ventilation (MV). ⋯ However, these non-significant differences between the tocilizumab and control groups may have been the result of baseline characteristics of the tocilizumab group, which were more severe than those of the control group. Based on low-quality evidence, there is no conclusive evidence that tocilizumab would provide any additional benefit to patients with severe COVID-19. Therefore, further recommendation of tocilizumab for COVID-19 cases should be halted until high-quality evidence from randomised controlled trials is available.

Severe burn patients undergo prolonged administration of sedatives and analgesics for burn care. There are currently no guidelines for the dose adaptation of sedation-analgesia in severe burn patients. ⋯ Scale-based lightening of continuous sedation-analgesia with repeated short general anesthesia for dressing is feasible in severe burn patients but failed to demonstrate a decrease in the duration of invasive mechanical ventilation.
