Abstract:
Objective To investigate the application of modified negative pressure closure drainage in early stage of snakebite .Methods 60 patients with early bite ulcer were selected as study objects ,and they were randomly divided into two groups according to the digital table .30 patients in the observation group received vacuum sealing drainage(VSD) combined with chymotrypsin continuous rinsing treatment .30 patients in the control group were given conventional dressing bandaging treatment .The two stage skin grafting time,wound healing time,complications,disa-bility rate,hospitalization time and C reactive protein ( CRP) levels of the two groups were observed .And the treatment effect was analyzed .Results The incidence rates of complications and disability in the observation group were 0.00％and 3.33％,respectively,which were significantly lower than 16.67％and 26.67％in the control group ,and the differences between the two groups were statistically significant (χ2 =4.356,6.405,all P<0.05).The CRP levels of 3 d and 7 d in the observation group were (15.8 ±1.7)mg/L,(6.9 ±1.6)mg/L,respectively,which in the control group were (18.6 ±2.3) mg/L,(13.8 ±1.9) mg/L,respectively,there were statistically significant differences between two groups(t=5.362,15.214,all P<0.01).The two stage skin grafting,wound healing,hospital stay of the observation group were (9.5 ±1.8) d,(24 ±1.8) d,(25.3 ±1.9) d,respectively,which were significantly shorter than those of the control group [(16.2 ±2.6)d,(32.0 ±3.2)d,(33.2 ±3.7)d],the differences were statistically significant(t=11.604,11.93410.403,all P<0.01).Conclusion For patients with injury of cobra bite to early ulcer,using VSD technology combined with chymotrypsin continuous irrigation ,can significantly reduce the level of CRP and the occurrence of complications and disability rate ,shorten the time of two stage skin grafting ,wound healing time,hospitalization time,reduce the pain of patients,it is the best treatment to accelerate recovery .
