Application of regional anesthesia under ultrasonic guidance for establishing puncture path of superficial tumor biopsy / 中华全科医师杂志

ABSTRACT

To explore the value of local anesthesia under ultrasonic guidance for establishing puncture path of superficial tumor.A total of 144 patients with superficial tumor received local pre-puncture anesthesia under ultrasonic guidance so that all lesions were targeted.Transient aggregation of narcotics was applied for raised (n =12) or superficial (n =15) skin lesions.The clarity of scanning acoustic window was enhanced,the puncture distance of tumor broadened and the mass of axial changed to obtain a longer lymph node cortex.The damage of blood vessels occurred easily due to tumor closeness to large blood vessel or shortened puncture path in 17 cases.Anesthetic drug was injected between tumor and blood vessels to enlarge the thickness for visualizing the puncture needle tract clearly.And puncture was accomplished under the guidance of color Doppler.Therefore a puncture path can be created effectively with local anesthesia by ultrasonic guidance.
