|Title||Effects of Noise Exposure on Blood Pressure and Pulse Rate of Employees in Intensive Care Units in Gaza Strip-Palestine|
The noise pollution is an important issue, especially in hospitals where the environmental problem caused nuisance. This study aims to know the relationship between occupational noise levels with arterial blood pressure (Systolic and Diastolic), and pulse rate for employees in general ICUs in Gaza Strip. The arterial blood pressure (Systolic and Diastolic) and pulse rate were measured before and after exposure to noise for five hours for 80 employees (72 males and 8 females). The ages of employees are ranged from 24 to 57 years. The duration of employment of those employees in the current job is ranged from 1 to 30 years. About 80 questionnaires were distributed among employees to obtain the personal information. In this study, two instruments were used: Sound Level Meter and Automatic Blood Pressure Monitor. Independent Samples t-test and Paired Samples t- test are used to detect differences among variables. Pearson correlation factor (R) and the P-value were used as a measure of the strength of the correlation among variables. The noise levels measured during working periods in ICUs were found to be between 52.52 and 65.74 A-Weighted Decibel with mean of 60.33A-Weighted Decibel, and then compared to international standards which is 45.0A-Weighted Decibel in the daytime. Results showed that there is an increased in the SPL coincide with the rise of average SBP, DBP and PR for all employees in all studied ICUs. In this study there is insignificant positive relationship (p-value > 0.05) between noise level and average of (SBP and DBP). But there is a significant positive relationship (p-value < 0.05) between noise level and average of PR. Whereas the correlation coefficient between noise level and SBP, DBP, and PR equals 0.158, 0.091 and 0.274, respectively. This study shows that continuous exposure to these levels of noise causes a rise in blood pressure and an increase in pulse rate. The systolic blood pressure mean is increased by 3.74 (mm-Hg), while the diastolic blood pressure mean is increased by 2.67 (mm-Hg), and finally, the pulse rate mean is increased by 2.69 (beats/minute) after exposure to noise. This study suggested some recommendations for employees in ICUs, officials and decision-makers to minimize the problem of noise pollution in intensive care units in Gaza Strip.
