<![CDATA[Transversus abdominis plane block (TAPB) merupakan salah satu teknik anestesia regional untuk memblokade nyeri saat dilakukan sayatan kulit di dinding abdomen. Penelitian ini bertujuan membandingkan penggunaan jarum sudut tumpul dengan jarum tuohy untuk TAPB terhadap penyebaran anestetik lokal pada operasi ginekologi. Jenis penelitian eksperimental dengan uji acak terkontrol buta tunggal dilakukan di Rumah Sakit Dr. Hasan Sadikin Bandung periode Juli–Agustus 2014. Penelitian ini dilakukan terhadap 30 wanita berusia 18–60 tahun dengan status fisik American Society of Anesthesiologists (ASA) I–II yang menjalani operasi ginekologi dalam anestesi umum. Penelitian ini dibagi menjadi dua kelompok yaitu jarum sudut tumpul dan jarum tuohy. Teknik TAPB dilakukan di kedua sisi abdomen menggunakan 20 mL bupivakain 0,125%. Sebelum dan sesudah TAPB dilakukan pencitraan ultrasonografi untuk membandingkan penyebaran anestetik lokal. Analisis statistika menggunakan Uji Mann-Whitney dan uji Z. Hasil penelitian ini menunjukkan penyebaran anestetik lokal pada kelompok jarum sudut tumpul 50% dan pada kelompok jarum tuohy 26,7% secara statistika berbeda bermakna (p<0,05). Simpulan, pada operasi ginekologi dengan teknik TAPB penggunaan jarum sudut tumpul lebih baik dibanding dengan jarum tuohy terhadap penyebaran anestetik lokal.Kata kunci: Jarum tuohy, jarum sudut tumpul, penyebaran anestetik lokal, transversus abdominis plane blockComparison between Short Bevel Needle and Tuohy Needle Use in Transversus Abdominis Plane Block on Local Anesthetic Spread During Gynecological SurgeriesTranversus abdominis plane block (TAPB) is one of the regional anesthesia techniques which enable multimodal analgesia involving skin incision in abdominal wall. This study aimed to compare the use of short bevel needle and tuohy needle for TAPB on the spread of local anesthetics in gynecological surgeries through a experimental randomized single blind trial. This study was conducted in Dr. Hasan Sadikin General Hospital Bandung on July–August 2014 to 30 woman between 18–60 years with the American Society of Anesthesiologists (ASA) physical status I–II underwent gynecological surgery under general anesthesia. The subjects were divided into 2 groups, short bevel needle and tuohy needle groups. The block was given on both sides of the abdomen using 20 mL of bupivacaine 0.125%. Before and after TAPB, an ultrasonography was performed to assess the spread of local anesthetics. Mann Whitney and Z test were used for statistical analysis. The results showed the spread of local anesthetic with short bevel needle was 50%, and with tuohy needle was 26.7%, the difference based on statistical analysis was significant (p<0.05). In conclusions, the use of dull angle needle is better than tuohy needle in the spread of local anesthetics in TAPB in patients undergo gynecological surgeries.Key words: Local anesthetic spreading, transversus abdominis plane block, short bevel needle, tuohy needle DOI: 10.15851/jap.v3n2.575]]>
