Nitrous oxide lowers TIVA costs in gynaecological surgery; confirms reduced propofol-alfentanil requirements.
Does nitrous oxide reduce the cost and drug requirement of intravenous anaesthesia in women undergoing routine gynaecological surgery?
Nitrous oxide can reduce the cost of total intravenous anaesthesia with propofol and alfentanil without increasing post-operative morbidity in routine gynaecological surgery.
Heath et al. (1996) studied this question.
