Feasibility of 18G trocar applied in jugular vein puncture for adults / 局解手术学杂志

ABSTRACT

Objective To investigate the feasibility of 18G trocar for central venous catheterization in adults.Methods Retrospective analyzed the clinical data of 60 patients with central venous catheterization under local anesthesia.These patients were randomly divided into the control group and the observation group.Selected the internal jugular vein as the site of the puncture catheter.The control group was punc-tured by conventional puncture needle while the observation group was punctured by the 18G trocar.Results There was no statistical differ-ence between the two groups in the success rate of final puncture and catheterization(P>0.05).Compared with the control group,the suc-cess rate of guidewire insert was higher,the puncture operation time was shorter,the pain score during puncture operation was lower,and post-operative patient satisfaction was higher in the observation group.The differences of the two groups were statistically significant(P<0.05). Conclusion 18G trocar can perform central venous catheterization successfully.This method has great advantages for awake patients,and it also worked in some cases with difficult wire insertion.
