Perbandingan Ketepatan Pengukuran Tekanan Balon Pipa Endotrakeal setelah Intubasi antara Metode Palpasi pada Pilot Balon dan Teknik Melepas Spuit secara Pasif

Abstract

Estimation of cuff pressure by palpating the pilot balloon is not accurate to determine the cuff pressure of endotracheal tube (ETT). Hence, this study we conducted to compare the accuracy of indirect measurements between pilot balloon palpation method (MP) and passive release technique (MSP). This was a single blind randomized crossover study performed in june 2014 at Dr. Hasan Sadikin General Hospital Bandung, in which patients received each technique and as a control group. Subjects were 94 patients aged 18−65 years old with American Society of Anesthesiologists (ASA) physical status I−III who underwent surgery requiring tracheal intubation. These subjects were randomized into two groups. After induction of anesthesia, the cuff was inflated with two different techniques: pilot balloon palpation technique (n=48) and passive release technique (n=46). Data were statistically analyzed using independent t-test and chi-square test. The mean cuff pressures of group MP was 57.7±26.0 cmH2O and for group MSP was 28.7±4.5 cmH2O, whereas the precision of measurements in the MSP group was 56.5% and 6.2% in the MP group (p<0.001). It is conclude that the palpation method for cuff inflation are inadequate. Therefore, it is suggested that the endotracheal tube cuff pressure must be kept within the optimal range using a standard manometer.
