Colloid solutions like albumin can be used in burn resuscitation after the first 24 hours to decrease edema and volume needs while blunting myocardial depression, but early use risks worsening capillary leak. Hypertonic saline may benefit high-risk burn patients by reducing fluid needs but requires close monitoring and is best used in specialized burn centers given the risks. The safety and efficacy of both colloids and hypertonic saline have been shown in pediatric and geriatric populations if lower tonicity solutions are used.
