May support hypotensive anesthesia in scoliosis surgery; leaves open need for randomized confirmation before practice change.
Does controlled hypotensive anesthesia reduce blood loss and operating time in patients undergoing scoliosis surgery?
Controlled hypotensive anesthesia during scoliosis surgery safely reduces blood loss and operative time compared to normotensive anesthesia.
McNeill et al. (1974) studied this question.
