Detaljerad beskrivning
fluid assessment using stroke volume change after passive leg raising maneuver will be applied. If stroke volume increase >10%, 500-mL bolus of lactated ringer will be given. Passive leg raising will be repeated until the patient is non-responder or 1500 mL were infused.
intraoperatively, heart rate and blood pressure will be monitored at 2 min intervals until 30 min after skin incision.

Aktiv komparator: Norepinephrine 5-mcg group
The study drug will be prepared by diluting 4000 mcg of NE in 400 mL of normal saline to achieve a concentration of 10 mcg/mL.
The assigned dose (5 mcg, 0.5 mL of the prepared solution) will then be further diluted with normal saline in a 10-mL syringe.
|
Norepinephrine dose of 5 mcg will be given if patient developed hypotension (mean arterial pressure <65 mmHg).
The norepinephrine bolus (5 mcg) will be repeated if mean arterial pressure is not restored within 2 min.
Norepinephrine infusion will be started if hypotension persisted after three boluses.

Norepinephrine dose of 10 mcg will be given if patient developed hypotension (mean arterial pressure <65 mmHg).
The norepinephrine bolus (10 mcg) will be repeated if mean arterial pressure is not restored within 2 min.
Norepinephrine infusion will be started if hypotension persisted after three boluses.

Area under a mean arterial pressure of 65 mmHg
Tidsram: from 0 min of induction of anesthesia until 30 min after skin incision
|
The area under a mean arterial pressure (MAP) of 65 mm Hg will be calculated by subtracting MAP measurements from 65 mm Hg, multiplying positive differences with the time difference (in minutes) between this MAP measurement and the consecutive MAP measurement, and summing the values
