What is Aortocaval compression?
Aortocaval compression (ACC) occurs when the gravid uterus compresses the maternal abdominal aorta and inferior vena cava (IVC). Compression of the IVC impedes venous return which decreases cardiac output (CO), and compression of the aorta may reduce uteroplacental perfusion which may result in fetal acidosis.
What is the purpose of manual uterine displacement?
Manual displacement of the uterus during Caesarean section. This enables good quality chest compression to continue with the chest remaining in an optimal position.
How do you perform Lud?
Manual LUD can be performed from the left of the patient (Figure 4), where the uterus is cupped and lifted up and leftward off the maternal vessels, or from the right of the patient (Figure 3), where the uterus is pushed upward and leftward off the maternal vessels.
What is the cause of supine hypotension during labor?
Supine hypotensive syndrome (also referred to as inferior vena cava compression syndrome) is caused when the gravid uterus compresses the inferior vena cava when a pregnant woman is in a supine position, leading to decreased venous return centrally.
When does Aortocaval compression occur?
Aortocaval compression syndrome is also known as a supine hypotensive syndrome. This pathophysiologic state occurs in a pregnant female, typically after 20 weeks gestation, when the patient is placed in the percent position.
How do you relieve Aortocaval compression?
Pregnant patient in cardiac arrest should receive high quality CPR with Manual Uterine Displacement (MUD) to relieve aortocaval compression. Relief of aortocaval compression must be maintained continuously during resuscitative efforts and continued if ROSC is achieved.
What is the recommended compression point for performing cardiac compressions?
Place 2 fingers on the lower half of the breastbone in the middle of the chest and press down by one-third of the depth of the chest (you may need to use one hand to do CPR depending on the size of the infant). Release the pressure. Pressing down and releasing is 1 compression.
What is AFI in sonography report?
An ultrasound examination can diagnose either too little or too much amniotic fluid. Doctors commonly measure the depth of the fluid in four quadrants in the uterus and add them up. This method of measuring amniotic fluid is referred to as the amniotic fluid index (AFI).
How can Aortocaval prevent compression?
Aortocaval compression can be avoided by lying in the full left lateral position. Unfortunately, it is not practical to carry out obstetric procedures in this position, so it is usual to modify the supine position by tilting the mother towards her left side.
How can Aortocaval syndrome be prevented?
Avoidance of the supine position in late pregnancy, to prevent aortocaval compression (ACC) by the gravid uterus, is a fundamental principle in the management of pregnant women, particularly during labor or at cesarean delivery.
