Risk factors of delayed wound recovery after Meek skin grafting in patients with extensive deep burn and its predictive value
To analyze the risk factors of delayed wound recovery after Meek skin grafting in patients with extensive deep burn and its predictive efficiency.
Methods
2
A total of 100 patients with extensive deep burn who underwent Meek skin grafting from August 2018 to November 2024 were selected,and they were divided into the normal group (
n
=79) and the delayed group (
n
=21) according to the wound healing time. The clinical data of all patients were collected,and the influencing factors of delayed wound recovery after Meek skin grafting in patients with extensive deep burn were analyzed by
Logistic
regression model,and the efficiency of the model was analyzed by the
receiver operating characteristic
(
ROC
) curve and the
Hosmer
-
Lemeshow
goodness-of-fit test,respectively.
Results
2
There were statistically significant differences in the body mass index,hospitalization time,burn index,burn area,donor skin area,number of postoperative dressing change,postoperative nutritional support,postoperative pain scores,and hospitalized blood glucose levels between the two groups (
P
<
0.05).
Logistic
regression analysis showed that high burn index (
OR
=1.086,
β
=0.082),large burn area (
OR
=1.155,
β
=0.144),fewer postoperative dressing change (
OR
=0.746,
β
=-0.293),lack of postoperative nutritional support (
OR
=6.439,
β
=1.86
2),high postoperative pain score (
OR
=4.483,
β
=1.500),and high level of hospitalized blood glucose (
OR
=2.251,
β
=0.811) were the influencing factors for delayed wound recovery after Meek skin grafting in patients with extensive deep burn (
P
<
0.05). The
ROC
curve revealed that the combined prediction of the above six influencing factors for delayed postoperative wound recovery had an
area under the
ROC
curve
(
AUC
) of 0.896,with a sensitivity and specificity of 88.00% and 89.10%,respectively; and the
Hosmer
-
Lemeshow
test result showed:
χ
2
=10.641,and
P
=0.223,indicating a high predictive efficacy and a certain calibration ability of the model.
Conclusion
2
The high burn index,large burn area,fewer postoperative dressing change,lack of postoperative nutritional support,high postoperative pain score and hospitalized blood glucose level were the influencing factors for delayed wound recovery after Meek skin grafting in patients with extensive deep burn,and the prediction model constructed by the above factors has good predictive ability,which can provide a reference for clinical treatment.
