Korelasi antara Panjang Garis Sternoakromion dan Titik Penyuntikan Blokade Pleksus Brakialis pada Anestesi Vertical Infraclavicular Block Menggunakan Pencitraan Ultrasonografi pada Pria Dewasa

Abstract

Anestesi regional untuk operasi di daerah lengan bawah dapat dilakukan blokade pleksus brakialis vertikal infraklavikula. Penelitian ini bertujuan menemukan korelasi antara panjang garis sternoakromion dan letak penyuntikan menggunakan pencitraan ultrasonografi untuk vertical infraclavicular block (VIB) pada pria dewasa. Penelitian potong lintang dengan mengukur titik tengah garis antara fosa jugularis dan akromion pada 48 pria dewasa. Pencitraan ultrasonografi dilakukan menggunakan probe linear untuk menentukan letak penyuntikan. Penelitian dilakukan di Rumah Sakit Dr. Hasan Sadikin Bandung periode Oktober 2011–Januari 2012. Hasil pengukuran didapatkan panjang garis sternoakromion kanan rata-rata 18,35±1,16 cm. dan kiri 18,39±1,22 cm. Titik tengah sternoakromion kanan rata-rata 9,18±0,59 cm dan kiri 9,19±0,61 cm. Jarak letak titik penyuntikan menggunakan ultrasonografi kanan 9,41±0,7 cm dan kiri 9,46±0,72. Terdapat korelasi positif (r kanan=0,874 dan r kiri=0,862) antara garis sternoakromion dan jarak letak titik penyuntikan menggunakan pencitraan ultrasonografi.

Correlation between the Sternoacromion Line Length and Plexus Brachialis Vertical Infraclavicular Block Injection Site Using Ultrasonography Scan on Adult Males

Abstract

Surgery on the lower part of the arm can be managed by brachial plexus vertical infraclavicular block. Needle placement for vertical infraclavicular block is not always at the midpoint of the sternoacromion line. The aim of this study was to find the correlation between sternoacromion length and needle placement using ultrasond scan for vertical infraclavicular block on adults males. This was a cross sectional study measuring the midlle point of sternoacromion line on 48 adult male volunteers whom never had any injury or operation on shoulder areas. Linear probe ultrasound was used to determine the needle placement. This study was conducted in Dr. Hasan Sadikin General Hospital Bandung within the period of October 2011–January 2012. Pearson correlation test and linear regression were used to analyze the data. Result of this study showed an average right strernoacromion length of 18.35±1.16 cm, an average left sternoacromion leght of 18.39±1.22 cm, an average midpoint right sternoacromion of 9.18±0.59 cm, and an average midmpoint left sternoacromion of 9.19±0.61. The average ultrasound right point was 9.41 cm and 9.46 cm for the left point. Hence, thereare significant correlations (r right=0.874, r left=0.862) between sternoacromion length and ultrasound injection point for vertical infraclavicular block.

Key words: Injection site for infraclavicular block, ultrasound scan, vertical infraclavicular block
