ReviewA "crush" course on rhabdomyolysis: risk stratification and clinical management update for the perioperative clinician.
Rhabdomyolysis, the release of myoglobin and other cellular breakdown products from necrotic muscle tissue, is seen in patients with crush injuries, drug overdose, malignant hyperthermia, muscular dystrophy, and with increasing frequency in obese patients undergoing routine procedures. For the perioperative clinician, managing the resultant shock, hyperkalemia, acidosis, and myoglobinuric acute kidney injury can present a significant challenge. Prompt recognition, hydration, and correction of metabolic disturbances may reduce or eliminate the need for long-term renal replacement therapy. This article reviews the pathophysiology and discusses key issues in the perioperative diagnosis, risk stratification, and management of rhabdomyolysis.

ReviewReview 1: Lung transplant-from donor selection to graft preparation.
For various end-stage lung diseases, lung transplantation remains one of the only viable treatment options. While the demand for lung transplantation has steadily risen over the last few decades, the availability of donor grafts is limited, which have resulted in progressively longer waiting lists. ⋯ Due to the donor shortages, there is ongoing discussion about the safe use of 'suboptimal' grafts to expand the donor pool. In this review, we will discuss the considerations around donor selection, donor-recipient matching, graft preparation and graft optimisation.

Observational StudySummary of 20 tracheal intubation by anesthesiologists for patients with severe COVID-19 pneumonia: retrospective case series.
SARS-CoV-2 pandemic is announced and it is very important to share our experience to the critical care community in the early stage. Urgent intubation team was organized by anesthesiologists and was dispatched upon request. We have retrospectively reviewed medical charts of 20 critically ill patients with Covid-19 pneumonia who required tracheal intubation from February 17 to March 19 in Wuhan No.1 hospital, China. ⋯ Although intubation improved SPO2, reduced PaCO2 and blood lactate, seven of 20 patients died within 7-days after tracheal intubation. Non-survivors showed significantly lower SPO2 and higher PaCO2 and blood lactate compared to survivors. For those who are anticipated to deteriorate severe pneumonia with poor prognosis, earlier respiratory support with tracheal intubation may be advised to improve outcome.

Randomized Controlled TrialComparison of the standard and triple airway maneuvering techniques for i-gel™ placement in patients undergoing elective surgery: a randomized controlled study.
The i-gel is a supraglottic airway device with non-inflatable cuff which can suffer insertion failure if its standard placement technique is implemented. The aim of this study was to compare the placement technique proposed by the manufacturer of i-gel with the triple airway maneuver in terms of successful device insertion time and first-attempt success. ⋯ The triple airway maneuver required less i-gel insertion time as compared with the standard placement technique. First-attempt success rates were similar with both techniques, although the triple airway maneuver was superior to the standard method as a rescue technique in failed insertions. We therefore recommend use of the triple airway maneuver in i-gel insertion.

Observational StudyFeasibility, safety, and economic consequences of using low flow anesthesia according to body weight.
Low flow anesthesia (LFA) provides a saving up to 75% and improves the dynamics of inhaled anesthesia gas, increases mucociliary clearance, maintains body temperature, and reduces water loss. LFA has been recommended for anesthesiologists in recent years to avoid high fresh gas flow (FGF). However, LFA use is limited due to associated risks. The main purpose of this study was to investigate whether LFA according to body weight, which is the main determinant of oxygen requirement, is feasible and safe in the normoxia range. The second aim was to show that this method can provide economic benefit. ⋯ We performed 10 mL/kg FGF speed without deviating from the safety limits to be FiO2:0.4 in donor hepatectomies, reducing the total costs 38% compared with 20 mL/kg FGF.
