Studies have demonstrated gaps between developed and developing countries in the quality of surgical and anaesthesia care. The aim of this review was to provide a critical overview of documented outcomes from the 2010s of anaesthesia-related cardiac arrest events in countries with largely differing Human Development Indexes (HDIs). The HDI ranges from 0 to 1, representing the lowest and highest levels of development, respectively. ⋯ This finding highlights the need to improve patient safety care in low-HDI countries. Anaesthesia patient safety has improved in high-HDI countries, but there is still a persistent gap in the health care systems of these countries and those of very high-HDI countries. Our review also found a consistent improvement in anaesthesia patient safety in very high-HDI countries.

Randomized Controlled Trial
Effect of combined versus sequential injection of 2% lidocaine and 0.5% bupivacaine on the onset and duration of supraclavicular brachial plexus block: A double blinded randomised controlled trial.
To assess whether sequential (one after the other with a delay of 120 s) or combined (freshly prepared mixture) administration of 2% lidocaine and 0.5% bupivacaine in supraclavicular brachial plexus block (SCBPB) provides faster onset and prolonged duration of block. ⋯ There was no advantage of sequential administration of 2% lidocaine and 0.5% bupivacaine over the administration of combination of both LAs in terms of onset and duration of block.

Randomized Controlled Trial
Perioperative high inspired oxygen fraction induces atelectasis in patients undergoing abdominal surgery: A randomized controlled trial.
We evaluated the feasibility of use and effects on postoperative atelectasis and complications of lower inspired oxygen fraction (FIO2) compared to conventional oxygen therapy. ⋯ Based on our findings, decreased inspired oxygen fraction during anesthesia and recovery did not cause hypoxic events, but instead reduced immediate postoperative atelectasis. The use of intraoperative conventional higher inspired oxygen did not afford any clinical advantages for postoperative recovery in abdominal surgery.

Observational Study
The impact of invasive respiratory support on the development of postoperative atrial fibrillation following cardiac surgery.
Postoperative atrial fibrillation (POAF) is a frequent complication after cardiac valve- or coronary artery bypass (CABG) surgery and is associated with increased mortality. While it is known that prolonged postoperative invasive ventilation triggers POAF, the impact of ventilatory settings on POAF development has not been studied yet. ⋯ The ventilatory settings of plateau pressure, driving pressure, and respiration rate after cardiac surgery influence POAF occurrence probability. Optimized postoperative care such as lung-protective ventilation and increased awareness towards postoperative ventilatory efforts should be considered to prevent POAF development and poor patient outcome.

Dexmedetomidine, which is commonly used for procedural sedation and as adjunct to general anesthesia for ambulatory procedures, may affect patient discharge from the post-anesthesia care unit (PACU). We hypothesized that intraoperative dexmedetomidine use in ambulatory surgery is associated with delayed discharge from the PACU and that this is modified by surgical duration and anesthesia type. ⋯ The intraoperative administration of dexmedetomidine was dose-dependently associated with a prolonged PACU length of stay. Clinicians should judiciously titrate dexmedetomidine, especially when using this long-acting drug for monitored anesthesia care for shorter procedures.
