Blood Pressure in Pregnancy
Conditions
Brief summary
Gestational hypertension is the main cause of maternal and fetal mortality, however, it has no definite effective treatment. nowadays, the stress management approaches are use for essential hypertension. So, this study aimed is study the effect of progressive muscular relaxation and breathing control technique on blood pressure during pregnancy. this 3-groups clinical trial has been done in Mashhad Health Centers and Governmental hospitals. 60 pregnant women with systolic blood pressure less than 135 mm Hg or diastolic blood pressure more than 85 mm Hg who met inclusion criteria were assigned into three groups of progressive muscular relaxation, breathing control and control. In tow experiment groups, exercises were controlled by one day personally and the rest by CD, BP before and after interventions was controlled for 4 weeks. In control group blood pressure was measured before and after 15 minutes with no intervention.
Interventions
BEHAVIORALmuscular relaxation
muscular relaxation was done using Jacobson by contracting and relaxing selected groups of muscles until total relaxation
BEHAVIORALbreath control
breathing control techniques include deep diaphragmatic breathing and decrease breath rate to 6-10/min
OTHERcontrol (routine care)
received routine care of clinic or health center and use drugs if necessary
