[Effects of 37 centigrade volume resuscitation on coagulation function and blood lactic acid in neonates with septic shock].

Objective: To investigate the effect of volume resuscitation with normal saline (NS) at 37 centigrade on the coagulation function and microcirculation of neonates with septic shock.

Methods: Children with septic shock admitted to neonatal intensive care unit (NICU) of the First Affiliated Hospital of Gannan Medical University were enrolled. Twenty-four newborns with septic shock were divided into two groups by random number table method (12 in each group), and were resuscitated with 10 mL/kg at 25 centigrade NS and 37 centigrade NS respectively on the basis of routine treatment. Factor II, V, VII, VIII, IX, X, and prothrombin time (PT), thrombin Time (TT), fibrinogen (FIB), activated partial thromboplastin time (APTT), D-Dimer (DD), lactic acid (Lac) were detected before treatment and 6 hours and 12 hours after treatment.

Results: The levels of coagulation factors II, V, VII, VIII, IX, X were not significantly changed before and after treatment in the two groups, and there was no significant difference between the two groups. After treatment, PT and APTT in both groups were gradually shortened, DD and Lac were gradually decreased, FIB were gradually increased, while TT had no significant change. Among them, PT, APTT, DD and Lac at 6 hours after treatment in 37 centigradeNS group were significantly lower than those before treatment [PT (s): 14.07±1.02 vs. 17.08±1.54, APTT (s): 54.83±12.39 vs. 69.17±16.36, DD (mg/L): 2.40±0.63 vs. 4.18±0.88, Lac (mmol/L): 2.84±0.82 vs. 5.98±1.17, all P < 0.05]; DD and Lac at 6 hours after treatment in 25 centigrade NS group were significantly lower than those before treatment [DD (mg/L): 3.13±0.84 vs. 4.16±1.04, Lac (mmol/L): 4.83±0.64 vs. 5.69±0.74, both P < 0.05], and PT at 12 hours after treatment was significantly shorter than that before treatment (s: 14.63±1.14 vs. 16.48±1.61, P < 0.01); FIB in both 25 centigrade NS group and 37 centigrade NS group at 12 hours after treatment were significantly higher than those before treatment (g/L: 2.83±0.83 vs. 1.58±0.43, 2.87±0.87 vs. 1.47±0.41, both P < 0.01), but TT had no significant change. The comparison between groups showed that PT, DD and Lac in the 37 centigrade NS group were significantly lower than those in the 25 centigrade NS group at 6 hours after treatment [PT (s): 14.07±1.02 vs. 15.69±1.21, DD (mg/L): 2.40±0.63 vs. 3.13±0.84, Lac (mmol/L): 2.84±0.82 vs. 4.83±0.64, all P < 0.05]; at 12 hours after treatment, PT, APTT and DD in the 37 centigrade NS group were significantly lower than those in the 25 centigrade NS group [PT (s): 13.26±0.91 vs. 14.63±1.14, APTT (s): 37.08±10.43 vs. 54.75±14.96, DD (mg/L): 1.20±0.59 vs. 2.06±0.69, all P < 0.01], and FIB was significantly higher than that in the 25 centigrade NS group (g/L: 2.87±0.87 vs. 2.83±0.83, P < 0.05).

Conclusions: Volume resuscitation at 37 centigrade can improve the coagulation function and microcirculation of newborns with septic shock.
