Determining the Effects of Nasopharyngeal Suction with Negative and Positive Pressure: Randomised Controlled Trial

Abstract

Objective: The study aims to determine the effects of nasopharyngeal suction with negative and positive pressure on pain level, respiratory parameters, and mucosal irritation in infants. Methods: This study was conducted as a posttest randomized controlled experimental research. The data was collected at G & ouml;ztepe Training and Research Hospital between January and November 2020. While the positive pressure suction method was applied to the experimental group, the negative pressure suction method was applied to the control group. Results: It is determined that the pain level mean scores at the 1 st and 5 th minutes after the suction procedure are lower in the experimental group than in the control group (p=0.01). p =0.01). SpO2 values at the 1st, st , 5th, th , and 15th th minutes after the procedure are significantly higher in the experimental group than in the control group (p=0.01). p =0.01). There is no statistically significant difference in the respiratory rate values between experimental and control groups (p>0.05). p >0.05). Conclusion: It is determined that the post-procedure pain level is lower and the SpO2 value is higher in the experimental group (positive pressure suction) compared to the control group (negative pressure suction). Both methods do not cause mucosal irritation, as well.
