Formulation of optimization measures
A random selection of 90 patients who underwent gastrointestinal surgery
in supine position in November 2017 was selected for the study. The
start time of anesthesia induction, the start time and end time of
catheterization, the start time and end time of prepare and drape the
operative site, and the start time of operation were obtained by the
monitoring recording in operating room. We calculate and record the time
of every procedure and between 2 adjacent procedures. After discussion
by 3 anesthesiologists, 3 surgeons, and 3 operating room nurses,
teamwork optimization measures will be established. (The researching
flow as show in the Fig 1)
