Blood Pressure Elevation by Ice in Thirty-eight Thai Volunteers

Abstract

Following immersion of subjects 'index fingers in ice, systolic and diastolic blood pressure were elevated in all normotensive subjects between 21.5 and 39.2 year of age (p<0.05). After thirty-minute pretreatment of the 21.5 year group and 39.2 year group of subjects with oral paracetamol (500 mg) with diazepam (2 mg) or paracetamol with diazepam (4 mg) respectively, blood pressure measurements was made before and after ice immersion of the index fingers. During the ice immersion, the systolic and diastolic blood pressure, after the drugs pretreatment, were significantly increased from the premeasurement levels in all subjects under study (p<0.05). The results suggest that ice induces increase in blood pressure of normotensives, which is unaffected by pretreatment of the subjects with paracetamol with diazepam.
