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
Ultrasound-guided erector spinae plane block for postoperative analgesia in patients undergoing open radical prostatectomy: A randomized, placebo-controlled trial.
The aim of this study was to evaluate the effect of ultrasound-guided erector spinae plane (ESP) block on postoperative pain in radical prostatectomy, which leads to both visceral and somatic pain. ⋯ In open radical prostatectomies, except for the first hour, ESP block is ineffective for pain scores and on morphine consumption compared to the placebo injection group in the postoperative period.

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.
