Abstract:
Objective:To analyze effects of pulse contour cardiac output (PiCCO) monitoring technology in amelioration of myocardial damage in fluid resuscitation of patients with large area burn in the early stage.
Methods:From November 2015 to November 2017, medical data of 52 patients with large area burn hospitalized in our unit, meeting the inclusion criteria, were analyzed retrospectively. Twenty-seven patients (18 males and 9 females) with age of (43±10)years in tradition group hospitalized from November 2015 to November 2016 were monitored by traditional monitoring methods for fluid resuscitation, and 25 patients (18 males and 7 females) with age of (44±10)years in PiCCO group hospitalized from December 2016 to November 2017 were monitored by traditional monitoring methods and PiCCO monitoring equipment for fluid resuscitation. Fluid infusion coefficients and total fluid replacement volume of patients in both groups at the first and second post burn hour (PBH) 24, as well as the levels of N terminal pro B type natriuretic peptide (NT-proBNP), cardiac troponin T (cTnT), and creatine kinase MB (CK-MB) immediately on admission and post burn day (PBD) 1, 2, 3, 4, 5, 6, and 7 were recorded. Data were processed with analysis of variance for repeated measurement, chi-square test, t test and Bonferroni correction, and Mann-Whitney U test and Bonferroni correction.
Results:(1) The fluid infusion coefficients of patients in tradition group at the first and second PBH 24 were respectively (1.42±0.10) and (0.94±0.14)mL·kg-1·% total body surface area (TBSA)-1, and those in PiCCO group were respectively (1.76±0.14) and (0.85±0.08) mL·kg-1·%TBSA-1. Fluid infusion coefficient and total fluid replacement volume at the first PBH 24 of patients in PiCCO group were significantly higher than those in tradition group (t=-9.775, -4.769, P<0.01). Fluid infusion coefficient at the second PBH 24 of patients in PiCCO group was significantly lower than that in tradition group (t=2.682, P<0.05). There was no statistically significant difference in total fluid replacement volume at the second PBH 24 in patients between the two groups (t=1.167, P>0.05). (2) Immediately on admission and PBD 1, 2, 3, 4, 5, 6, and 7, the levels of NT-proBNP of patients in tradition group were respectively 518 (320, 763), 236 (98, 250), 139 (62, 231), 172 (104, 185), 296 (225, 341), 727 (642, 921), 1 840 (1 357, 2 081), 1 005 (671, 1 297) pg/mL, and those in PiCCO group were respectively 444 (206, 601), 66 (29, 73), 54(28, 75), 139(101, 175), 199 (106, 279), 576 (333, 837), 833 (466, 1 080), 485 (225, 710) pg/mL. The levels of NT-proBNP of patients in PiCCO group on PBD 1, 2, 6, and 7 were significantly lower than those in tradition group (Z=-5.004, -3.967, -5.285, -4.626, P<0.01). The levels of NT-proBNP immediately on admission and PBD 3, 4, and 5 in patients between the two groups were close (Z=-0.834, -0.806, -2.665, -2.153, P>0.05). (3) Immediately on admission and PBD 1, 2, 3, 4, 5, 6, and 7, the levels of cTnT of patients in tradition group were respectively (42±15), (21±12), (17±7), (11±4), (12±4), (94±32), (88±23), (42±23) pg/L, and those in PiCCO group were respectively (37±15), (9±3), (10±3), (13±3), (12±5), (85±30), (60±26), (22±14) pg/L. The levels of cTnT of patients in PiCCO group on PBD 1, 2, 6, and 7 were significantly lower than those in tradition group (t=5.227, 4.751, 4.239, 3.845, P<0.01). The levels of cTnT immediately on admission and PBD 3, 4, and 5 of patients between the two groups were close (t=1.098, -1.562, -0.117, 1.107, P>0.05). (4) The levels of CK-MB of patients in PiCCO group on PBD 3, 6, and 7 were significantly lower than those in tradition group (t=3.123, 4.103, 3.178, P<0.05 or P<0.01). The levels of CK-MB immediately on admission and PBD 1, 2, 4, and 5 in patients between the two groups were close (t=0.351, 1.868, 1.100, 0.798, 2.094, P>0.05).
Conclusions:PiCCO monitoring technology can monitor and guide fluid resuscitation of patients with large area burn in the early stage more scientifically and reasonably, and the effect of reducing myocardial damage is better than traditional monitoring methods.
