Declarations
:
: The study was approved by the Institutional Review Board (IRB), Regional Cancer Centre, Thiruvananthapuram. IRB no. 11/2016/05. Hospital Ethical Committee clearance was waived by the Institutional Review Board as it did not involve any newer intervention rather than applying BIS leads over the forehead. The cost of the BIS electrode was also not charged from the patients as it was covered by the hospital health insurance scheme. The study was commenced after obtaining written informed consent from the patients.
