Intraoperative mild hyperoxia may be associated with improved survival after off-pump coronary artery bypass grafting: a retrospective observational study.

Background: The effect of hyperoxia due to supplemental oxygen administration on postoperative outcomes in patients undergoing cardiac surgery remains unclear. This retrospective study aimed to evaluate the relationship between intraoperative oxygen tension and mortality after off-pump coronary artery bypass grafting (OPCAB).

Methods: The study included adult patients who underwent isolated OPCAB between July 2010 and June 2020.

Changes in the incidence of cardiopulmonary resuscitation before and after implementation of the Life-Sustaining Treatment Decisions Act.

Background: The Life-Sustaining Treatment (LST) Decisions Act allows withholding and withdrawal of LST, including cardiopulmonary resuscitation (CPR). In the present study, the incidence of CPR before and after implementation of the Act was compared.

Methods: This was a retrospective review involving hospitalized patients who underwent CPR at a single center between February 2016 and January 2020 (pre-implementation period, February 2016 to January 2018; post-implementation period, February 2018 to January 2020).

Effects of tip-manipulated stylet angle on intubation using the GlideScope videolaryngoscope in children: A prospective randomized controlled trial.

Background: An optimal endotracheal tube curve can be a key factor in successful intubation using the GlideScope videolaryngoscope.

Aims: This study aimed to evaluate the effects of tube tip-modified stylet curve on the intubation time in children.

Methods: Children aged 1-5 years were randomly assigned to either the standard curve (group S, n = 60) or tip-modified curve (group T, n = 60) groups.
