Sevofluran consumption and changes of o2, co2 during lowflow anesthesia with ecoflow at fresh gas flow 0.5 liter/min for abdominal surgery in elderly patients
Overview
Abstract:
Object:
1.
Evaluating the consumption of Sevofluran during low
flow anesthesia with ecoflow at fresh gas flow 0.5 L/min for abdominal surgery
in elderly patients.
2.
Describing changes
in O2, CO2 during low flow
anesthesia with ecoflow at fresh gas flow 0.5 L/min for abdominal surgery in
elderly patients.
Materials
and methods: 30 patients, ASA
I, II,III aged ≥ 60 years undergoing opened abdominal surgery were included.
The inhalation anesthetic maintenance was done with low flow at FGF 0.5L / min,
FiO2 50%. A standardized anesthetic monitorings (MAC-Sevofluran, entropy, SPI,
TOF, heart rate, MAP, SPO2, EtCO2,FiO2, blood gas) were
utilized.
Results
and conclusions: The
average amount of Sevoflurane consumed during low flow anesthesia with ecoflow at fresh gas
flow 0.5 L/min for abdominal surgery in elderly patients was
0.15ml/min. Of
the 30 patients studied, 17 patients (57.6%) had a decrease in FiO2 to 25% (PaO2=
74.3±44.3
mmHg)
after 75.8±27.4 minutes and
five patients (16.7%) had EtCO2 increased to 45 mmHg
after 82.2±36.4 minutes.
FiO2 and EtCO2 at the time of the starting lowflow anesthesia to the end of
lowflow anesthesia was statistically significantly increased with P <0.05.
