Perbandingan Ketepatan Ukuran Classic Laryngeal Mask Airway antara Metode Berat Badan dan Lebar Lidah
Abstract
Classic laryngeal mask airway (CLMA) merupakan alat yang digunakan untuk manajemen jalan napas, baik untuk pengganti ventilasi sungkup wajah maupun intubasi endotrakeal. Pemilihan ukuran yang tepat penting untuk efektivitas penggunaan CLMA. Saat ini pemilihan ukuran berdasar atas metode berat badan. Menurut sebuah studi terbaru metode pengukuran lebar lidah lebik baik daripada metode berat badan. Tujuan penelitian ini adalah mengetahui ketepatan ukuran CLMA antara metode berat badan dan lebar lidah yang dinilai dengan skor fiberoptik dan oropharyngeal leak pressure di RSUP Dr. Hasan Sadikin Bandung. Penelitian ini dilakukan pada bulan Februari 2018 menggunakan uji eksperimental analitik crossection setiap subjek mendapat dua perlakuan yang berbeda antara kedua metode. Uji statistik menggunakan uji chi-square untuk skor fiberoptik dan uji t berpasangan untuk oropharyngeal leak pressure. Hasil penelitian skor fiberoptik lebih optimal daripada metode lebar lidah. Oropharyngeal leak pressure pada metode berat badan rerata 23,00±1,732 CmH20 sedangkan metode lebar lidah rerata 19,13±1,684 CmH20. Secara statistik diperoleh nilai p<0,05. Simpulan, metode pengukuran lebar lidah adalah alternatif yang mudah dan baik dalam pemilihan ukuran CLMA pasien dewasa.

Comparison of Classic Laryngeal Mask Airway Size Accuracy between Body Weight Method and Tongue width Method
Classic laryngeal mask airway (CLMA) is an airway management device that can be used to replace bag valve mask ventilation or endotracheal intubation. Choosing the right size of CLMA is important for the effectiveness of CLMA. Currently, the size of CLMA is selected based on the body weight. However, a recent study suggested that tongue width is a better indicator for size selection than the body weight. The purpose of this study was to assess the accuracy of CLMA size selection using the body weight method and tongue-width method. The assessment was performed using the fiberoptic score and oropharyngeal leak pressure. This was an experimental analytic cross-sectional study conducted in Dr. Hasan Sadikin General Hospital Bandung in February 2018. Each subject in this study received two different treatments using the two methods. The results were analyzed using chi-square for the fiberoptic score and paired t test for the oropharyngeal leak pressure. The fiberoptic score was more optimum when tongue width method was used when compared to the weight method. The oropharyngeal leak pressure in the weight method group was 23.00±1.732 CmH20 while the pressure in the tongue-width method was 19.13±1.684 CmH20 (p value <0.05). In conclusion, the tongue width measurement is an easy and good alternative in the selecting the CLMA size in adult patients.
