EFFECT OF Lavandola angustifolia AROMATHERAPY VERSUS MIDAZOLAM ON VITAL SIGNS IN CRITICALLY ILL PATIENTS

Lavandola angustifolia is a plant from labiateae family that might be used against free radicals and also as
tranquilizer with anti-stress and anti-anxiety. Since there are few randomized clinical trials in this era especially for admitted patients in intensive care unit (ICU); this study was performed to compare the systolic and diastolic blood pressure, pulse rate, and respiratory rate in two groups of patients in ICU who received Lavandola angustifolia preparation versus midazolam as a conventional sedative drug. In this randomized clinical trial, 64 patients were randomly assigned (with simple random manner) to receive either aromatherapy with Lavandola angustifolia drop 2% developed by Bonyan Mehr Ejaz Kaivr Shargh Iran Company in Shahroud, Iran (n=33) or midazolam (n=31).
The Lavandola angustifolia drop was respired by a patch inside the oxygen mask 20 minutes daily. Also, the
midazolam was injected intravenously with a dose of 0.05 mg/kg. The vital signs were assessed before intervention
and then every 10 minutes up to one hour. The pulse rate and respiratory rates were significantly lower in
Aromatherapy group and the systolic and diastolic blood pressures were significantly higher in this group in
comparison with midazolam group (P=0.0001). Totally, according to the obtained results, it may be concluded that
vital signs had more stability in aromatherapy with Lavandola angustifolia in comparison with midazolam.
