Here is a beautiful prayer from the BCP.
O most mighty and merciful God, in this time of grievous sickness, we flee unto thee for succour. Deliver us, we beseech thee, from our peril; give strength and skill to all those who minister to the sick; prosper the means made use of for their cure; and grant that, perceiving how frail and uncertain life is, may apply our hearts unto that heavenly wisdom which leadeth to eternal life; through Jesus Christ our Lord. Amen
