EFFECT OF BLOOD PRESSURE MEASUREMENT IN DIFFERENT POSITIONS ON BLOOD PRESSURE VALUES AND ANXIETY LEVELS IN PREGNANT WOMEN WITH PREECLAMPSIA (PREECLAMPSIA)

Aim: This study examined the effects of blood pressure measurement in different positions on diastolic and systolic blood pressure values and anxiety levels in pregnant women diagnosed with preeclampsia.

Method: The study was conducted between March and June 2024 as a pre-test post-test quasi-experimental study with 96 pregnant women diagnosed with preeclampsia in the perinatology department of a training and research hospital. Participants were divided into three groups and their blood pressures were measured in the left lateral, right lateral and semi-Fowler positions. Data were collected using an introductory information form and the State Anxiety Scale.

Study Overview

• Status: Completed
• Conditions: Preeclampsia; Blood Pressure Check (Hypertension Screening)
• Intervention / Treatment: Other: Right Lateral Position; Other: Left Lateral Position; Other: Semi Fowler Position (45° Fowler)

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Child
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• Being primigravida (first pregnancy),

  • Being in the third trimester of pregnancy,
  • Being between the ages of 18-45,
  • Being diagnosed with preeclampsia,
  • Having an arm circumference of less than 36 cm,
  • Having a history of hospitalization of at least 24 hours (in order to minimize anxiety, uncertainty, lack of information and disorientation related to hospitalization).

Exclusion Criteria:

• • Presence of a physical disability that would make it difficult to perform the positions included in the study (e.g. loss of extremity),

  • Presence of decompensated disease (e.g. eclampsia, pulmonary edema),
  • Presence of a history of cardiological disease,
  • Diagnosis of obstructive sleep apnea,
  • Presence of additional risk factors other than preeclampsia (e.g. threat of premature birth, placental anomalies).

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Right Lateral Position; The pregnant woman was placed in the right lateral position on the patient bed. Her head was supported by a medium-height pillow. The right arm to be measured was held at heart level and extended at a 45° angle to the body. Considering that taking measurements from the left arm above heart level could lower blood pressure values, both measurements were made only from the right arm.	Other: Right Lateral Position; Participants rested for 10 minutes in a fully seated position, leaning their backs on a chair, without crossing their legs and placing their feet parallel to the floor. During this time, the arm to be measured was kept at heart level.
Experimental: Left Lateral Position; The pregnant patient was lying in the left lateral position on her bed, her head supported by a pillow of medium height. The left arm to be measured was positioned at heart level and supported by a pillow underneath. Blood pressure was measured using the arm extended at a 45° angle to the body in the left lateral position. Considering that taking measurements from the right arm above heart level may lower blood pressure values, both measurements were taken from the left arm only.	Other: Left Lateral Position; Left Lateral Position
Experimental: Semi Fowler Position (45° Fowler); The pregnant woman was laid on her back at a 45° angle on the patient bed. Her head was supported with a medium-height pillow. The arm to be measured was held at heart level and supported with a pillow underneath to provide the appropriate position.	Other: Semi Fowler Position (45° Fowler); Semi Fowler Position (45° Fowler)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
blood pressure measurement	The effect of blood pressure measurement in different positions on diastolic and systolic blood pressure values in pregnant women diagnosed with preeclampsia will be examined. Measurement will be made with a blood pressure device. Systolic pressure and diastolic pressure will be measured in mmhg.	4 month
anxiety levels	The effects of blood pressure measurement in different positions on anxiety levels in pregnant women diagnosed with preeclampsia will be measured. The anxiety level will be measured with the state anxiety scale. The score obtained from the scale varies between 20 and 80. A high score indicates a high level of anxiety, a low score indicates a low level of anxiety. The same applies when interpreting scores according to percentile rank. In other words, a low percentile rank (1, 5, 10) indicates low anxiety. The average score level determined in applications varies between 36 and 41.	4 month
