Assessment of the vascular status following limb fracture in children is important to evaluate the risk of compartment syndrome, which is an emergency condition.
To establish a simple and efficient grading scale of limb perfusion in children undergoing surgery for limb fracture.
This retrospective study included pediatric patients with a limb fracture and postoperative plaster fixation who were admitted at The Department of Pediatric Orthopedics of Xinhua Hospital between February 2017 and August 2017. The outcome was poor limb perfusion, which is defined as the postoperative use of mannitol. The children were divided into two groups: The normal perfusion group and the poor perfusion group. Key risk factors have been selected by univariable analyses to establish the Grading Scale for Vascular Status.
A total of 161 patients were included in the study: 85 in the normal perfusion group and 76 in the poor perfusion group. There were no significant differences in age, sex, body mass index, ethnicity, cause of fracture, fixation, or site of fracture between the two groups. After surgery, the skin temperature (P = 0.048) and skin color (P < 0.001) of the affected limb were significantly different between the two groups. The relative risk and 95% confidence interval for skin temperature of the affected limb, skin color, and range of motion of the affected limb are 2.18 (1.84-2.59), 2.89 (2.28-3.66), and 2.16 (1.83-2.56), respectively. The grading scale was established based on those three factors (score range: 0-3 points). Forty-one patients (32.5%) with score 0 had poor limb perfusion; all patients with scores 1 (n = 32) and 2 (n = 3) had poor limb perfusion (both 100%).
In children undergoing surgery for limb fracture, a higher Grading Scale for Vascular Status score is associated with a higher occurrence of poor limb perfusion. A prospective study is required for validation.
Core Tip: The assessment of the vascular status following limb fracture in children is important to evaluate the risk of compartment syndrome, which is an emergency condition. This study aims to establish a simple and efficient grading scale system of limb perfusion in children undergoing surgery for limb fracture, the Grading Scale for Vascular Status (GSVS). The results strongly suggest that in children undergoing surgery following limb fracture, a higher GSVS score is associated with a higher occurrence of poor limb perfusion. A prospective study is required for validation, but GSVS could help prevent compartment syndrome in children after limb fracture.
