Control of Bleeding in Endoscopic Skull Base Surgery: Current Concepts to Improve Hemostasis Table 3 Review of controlled hypotension series in endoscopic endonasal surgery.
Author (Year) Target mean arterial pressure Grading quality of surgical field Blood loss Comment
Boezaart et al. [32 ] (1995)
>65 mmHg 60–64 mmHg 55–59 mmHg 50–54 mmHg In SNP group*
In Esm group*
N/A The optimum surgical conditions were provided with minimum Esm-induced hypotension (MAP > 65 mmHg); conversely, SNP induced hypotension (MAP 50–54 mmHg)
Jacobi et al. [33 ] (2000) Moderate controlled hypotension with SNP (65–75 mmHg)
mL
(i) Total blood loss and grading quality of surgical field did not show significant difference between the groups (ii) There was no correlation between blood loss and MAP Normotensive situation

Using quality scale is proposed by Fromme et al. [35 ];
Using numeric rating scale. SNP: sodium nitropusside; Esm: esmolol; MAP: mean arterial pressure.
