After induction, intubation was performed and in all patients ventilation was performed with tidal volume of 8 ml/kg, inspiratory/expiratory ratio of 1/2 to maintain target ETCO2
of 35-40 mmHg.
All the study participants were monitored intraoperatively by 5 lead ECG, SpO2, automated NIBP, ETCO2
, core temperature and hourly urine output.
At this point of the procedure, the patient was ventilated with low tidal volumes of 300 and respiratory rate of 16-20 to keep the ETCO2
at around 40.

rose up to 80 mmHg and after 2 hours lowered to 45 mmHg.
La capnografia debe realizarse con un monitoreo continuo, manteniendo un ETCO2
entre 32 y 34 mmHg.
6] Immediately bag ventilation was started, other faculty observed for waveform capnography and ETCO2
level and simultaneously auscultation of chest and epigastrium was also done.
The data recorded during the surgery (HR NBP ETCO2
ETSevo) were not significantly different among the three groups.

Monitors used were ECG, Pulse oximeter, ETCO2
Maintenance of anesthesia was done with 1-2MAC sevoflourane in group 1 (n=22) keepingO2 at 50% and N2O at 50% and with 1-2 MAC at 1:2 and respiratory frequency was maintained ina way to keep ETCO2
at 35-40 mmHg which makes normocapnia possible.
After cricoid pressure was applied and the trachea was intubated anesthesia was maintained with sevoflurane in a mixture of nitrous oxide 2L/min and oxygen 2 L/min and the lungs of all patients were mechanically ventilated to maintain an ETCO2
concentration of 3237 mmHg.
