May support SNP use for controlled hypotension in head-up position; leaves open prospective confirmation.
Does sodium nitroprusside safely produce controlled hypotension without compromising cardiac output in anesthetized adult patients in the head-up position?
Sodium nitroprusside effectively produces controlled hypotension in the head-up position while maintaining or increasing cardiac output, similar to its effects in supine patients.
Stoelting et al. (1977) studied this question.
