Deep venous puncture pathway in severely burned patients during their shock reabsorb phase and 3 days thereafter:A clinical study on duration of cannulation

To explore the appropriate duration of cannulation by deep venous puncture pathway in severely burned patients during their shock reabsorb phase and 3 days thereafter.Methods This prospective study was conducted at our unit over two years,from Sept 1,2000 to Sept 1,2002.According to the demands of the design,given cannulated by deep venous puncture pathway,burned patients with 30% TBSA or more but without severe inhalation injuries were recruited in the present study and,were randomized into two groups,one group subjected to be cannulated with pathway-alteration within 7 days (alteration group),the other group without pathway-alteration within the similar period(non-alteration group),the incidence of CAC,CAI,and CAB was gained and compared.Results A total of 121 qualified patients had finished the study,the alteration group had 71 cases,the non-alteration group 50 cases.The incidence of CAC in non-alteration group was significant higher than that in alteration one,but the differences of the incidence of CAI and CAB between groups were insignificant.Conclusion The seven days duration of cannulation by deep venous puncture pathway in severely burned patients during their shock reabsorb phase and 3 days thereafter is safe.16 refs,2 tabs.
