“…It minimises retraction, reduces local hypoperfusion and cerebral ischemia, and, therefore, minimises the risk of complication and postoperative neurological deficit [1,3]. Several methods have been used to achieve a good and relaxed brain, such as hyperventilation, cerebrospinal fluid drainage, head position correction, and administration of hyperosmolar agents [4].

Background Hypertonic saline and mannitol are hyperosmolar agents frequently used to lower ICP and relax the brain during surgeries. Several methods have been used to achieve a good and relaxed brain, such as hyperventilation, cerebrospinal fluid drainage, head position correction, and administration of hyperosmolar agents. Comparing equiosmolar doses between hypertonic saline and mannitol in patients undergoing elective craniotomies is important to further notice the differences in several outcomes. This study aims to compare the outcome of hypertonic saline versus mannitol on brain relaxation in patients undergoing elective craniotomy. Results 10 articles from 2007 to 2021 were included. Hypertonic saline is associated with better brain relaxation (OR = 1.84, 95% CI 1.31–2.59; P = 0.001) but significantly increase blood natrium level, both serum and arterial (MD = 3.03, 95% CI 1.70–4.36; P = < 0.001 and MD = 7.14, 95% CI 0.04–14.24; P = < 0.001, respectively). Mannitol was associated with increased fluid input and urine output (SMD = − 0.56, 95% CI − 0.98 to − 0.15; P = < 0.001 and SMD = − 0.96, 95% CI − 1.42 to − 0.50; P = < 0.001, respectively). Serum osmolality and hemodynamic parameters difference was insignificant. Conclusions Hypertonic saline is associated with significantly better brain relaxation score and increased blood sodium level without increase in urine. This may prove to be clinically significant in patients with electrolyte imbalance.
