Clinical application of ultrasound bronchoscopy guided needle aspiration biopsy under general anesthesia / 中国内镜杂志

ABSTRACT

Objective To explore the application of transbronchial needle aspiration biopsy (EBUS-TBNA) combined with ultrasound bronchoscopy under the general anesthesia (intravenous anesthesia combined with laryngeal mask). Methods 103 patients with EBUS-TBNA from June 2015 to October 2016 were randomly divided into local anesthesia group and general anesthesia group. The anesthesia group was anesthetized with intravenous anesthesia combined with laryngeal mask, local anesthesia group with conventional tetracaine local anesthesia. The differences in the average number of puncture needles, the diagnosis rate, the operation time, the complications and the comfort of each group were analyzed retrospectively. Results The average number of puncture needle in each group was 5.6 times, and the local anesthesia group was 3.1 times. The diagnosis rate of general anesthesia group was 94.12% and local anesthesia group was 78.85%. There was significant difference between the two groups (χ2 = 5.11, P = 0.024). The average operation time in the general anesthesia group was (14.61 ± 1.52), the local anesthesia group was (32.52 ± 4.14), they had significant difference (t = 29.01, P = 0.000). The number of patients in bleeding and cough of the general anesthesia group were lower than those in the local anesthesia group (χ2 = 4.31, 103.00, P = 0.038, 0.000, respectively). Conclusions EBUS-TBNA under general anesthesia has high diagnostic rate, shortoperating time, painlessness, high comfort and reduce operational risk, worthy of promoting clinical application.
