The present study was to evaluate the effectiveness of colloid compared with crystalloids for fluid resuscitation in critical burn patients with total burn surface area ≥50%.

Extensive burn patients are some of the most challenging critically ill patients who may have multiple-system organ failure with life-threatening complications.Over time, several resuscitation formulae have been proposed to guide burn resuscitation and the best known ones are Parkland and Evans formulae. The main controversy between the two formulae also focuses on whether to infuse the colloid in the first 24 h.Controversy continues and the conflicting results left many clinicians unsure about the effect of colloids on fluid resuscitation in extensive burn patients who suffer higher risk of hypovolaemia, abdominal compartment syndrome (ACS), multiple organs dysfunction and mortality. To address this uncertainty, we conducted a prospective, randomized, controlled clinical trial to compare fluid resuscitation in extensive burns guided by Parkland formulae with TMMU formulae as a modified Evans formula routinely used in China.

Inclusion Criteria:

• burn patients with total burn surface area ≥50% and full thickness burn surface area ≥30%.

Exclusion Criteria:

• age <18 yrs, time between burn injury and fluid infusion > 4 h, time arriving at our burn centre > 6 h, pre-existing medical illnesses compromising the cardiopulmonary reserve or those need for compassionate care only.

This study was performed in the Department of Burn Intensive Care of the Tangdu Hospital, an academic hospital of the Fourth Military Medical University of Xi'an. populaitons were extensive burns who admitted to our hospital within 4 h since burn injury.
