Informed consent was sought from all conscious participants and or their legally authorized representatives (for the unconscious) who endorsed their signatures or thumb prints on the consent form document, having been made to understand the risks and benefits of the study. When patients regained consciousness, their consent was re-obtained, and they were free to withdraw their consent at any stage of the study. Withdrawal of consent by any patient did not affect the quality of treatment or impinge on their entitlements.
