Perbandingan Angka Keberhasilan Pemasangan Laryngeal Mask Airway (LMA) Jenis Klasik pada Usaha Pertama antara Teknik Balon Dikempiskan dan Dikembangkan Sebagian pada Pasien Dewasa

Abstract

Classic laryngeal mask airway (cLMA) is the most widely used supraglottic airway device and is a satisfactory alternative to endotracheal intubation. The purpose of this study was to compare the success rate of cLMA insertion using fully deflated technique and partially inflated technique in adult patients. This was a complete randomized controlled single blind trial on 70 patients, 18–60 years old, American Society of Anesthesiologists (ASA) I–II, who underwent elective surgery in general anesthesia and in whom the use of LMA was not contraindicated. This study was performed at the Central Operating Theater, Dr. Hasan Sadikin General Hospital,Bandung. After using a permutation block randomization, the subjects were divided into fully deflated technique group and partially inflated technique group. Correct placement in first attempt was confirmed. Data were analyzed using chi-square test and Mann-Whitney test, where a p value of <0.05 was considered significant. The study was held in a period of February toMarch 2015. The results of this study showed that the partially inflated technique was more successful, 33 of 35, than the fully deflated technique, 27 of 35, on the first attempt. In addition, the statistical analysis results also showed that the ratio of success rate between both treatment groups of cLMA insertion was significantly different (p<0.05). The success rate of partially inflated technique of cLMA insertion iss higher than the fully deflated technique in adult patients.
