Intraoperative Movements Scale (IOMs) [10]
Grade 0 = No movement
Grade 1 = Ankles movement (feet dorso-flexion)
Non procedure interferent
It could deepen analgesia
Grade 2 = Knee movements (legs flexo-extension) (with/without
movements)
Non procedure interference (aspiration could stop)
It could deepen analgesia/anesthesia.
Grade 3 = Pelvis/ hips movements (with/without legs/thighs
movements)
Aspiration must be stopped
Must be deepen analgesia/anesthesia
Grade 4 = Rude movements of the pelvis, chest and/or arm
Aspiration must be stopped
Must be deepen anesthesia
In group BIS continuous propofol infusion (10mg/kg/hour) was started
immediately after anesthesia induction. In these patients, the propofol
infusion rate was adjusted to keep the BIS value between 40-60 during
the procedure. If the BIS value was above the target level, the propofol
infusion rate was increased by 20%, and if the BIS was below the target
level, the infusion rate was decreased by 20%. Propofol infusion was
stopped when oocyte aspiration was completed.
During the procedure, all the patients received paracetamol (1gr)
intravenously, and diclofenac sodium 100mg suppository was applied at
the end of the procedure for postoperative analgesia. The laryngeal mask
was removed when the patients opened the eyes.
Heart rate, oxygen saturation, systolic, diastolic, and mean blood
pressure were recorded before anesthesia, at the 5th, 10th, and 15th
minutes of the procedure, at the end of the procedure and when the
patient was awake. BIS values were also recorded in the group BIS at
the same time points. Bradycardia (defined as heart rate <
25% from baseline or < 50 beats/min), hypotension (defined as
systolic blood pressure < 25% from baseline or < 90
mmHg), and presence of rigidity were recorded. In the presence of
bradycardia, 0.5mg atropine was administered. In the presence of
hypotension, 5mg ephedrine was administered.
The duration of anesthesia and duration of procedure were recorded. The
total amount of propofol was recorded. After the removal of the
laryngeal mask, the time to reach 5 in the MOASs was recorded in the
operating room.
