What is hypotonic contraction?

What is hypotonic contraction?

Excerpt. Hypotonic labor is an abnormal labor pattern, notable especially during the active phase of labor, characterized by poor and inadequate uterine contractions that are ineffective to cause cervical dilation, effacement, and fetal descent, leading to a prolonged or protracted delivery.

What causes hypertonic uterine dysfunction?

Inappropriately high concentrations of oxytocin can cause uterine hypertonus, when the uterus does not relax between contractions, and fetal distress can occur.

What is D cells in labor?

Definition. Late deceleration is defined as a visually apparent, gradual decrease in the fetal heart rate typically following the uterine contraction. The gradual decrease is defined as, from onset to nadir taking 30 seconds or more.

What is the effect of precipitate labor in a fetus *?

When a mother goes into precipitous labor, the baby is at increased risk for infection if the actual delivery happens in an unsterile environment instead of in a delivery room at a hospital or birthing center. Your baby might also be more likely to breathe in some of the amniotic fluid in this situation.

Why are my contractions so close together?

Non-progressing contractions. Contractions that are not getting longer, stronger and closer together. This may mean that the contractions are not opening the cervix. It usually means that other work is being done, such as turning your baby to a different position, softening or thinning the cervix.

Why is uterine Tachysystole bad?

The presence of tachysystole increases the chance of neonatal morbidity. In addition, excessive uterine activity has the potential to directly affect the uterus, especially if a prior cesarean section was performed, because the weakened tissue from the uterine scar is vulnerable.

What causes uterine Tachysystole?

“Tachysystole” means an abnormally rapid rate of muscle contraction. When Pitocin (a hormone used to induce contractions) is administered to pregnant women to induce or speed labor, it can cause uterine tachysystole – a condition in which contractions occur six times in a period of ten minutes.

What do fetal accelerations mean?

Accelerations are short-term rises in the heart rate of at least 15 beats per minute, lasting at least 15 seconds. Accelerations are normal and healthy. They tell the doctor that the baby has an adequate oxygen supply, which is critical.

What is a hypotonic contraction?

hypotonic labor. A condition during the active phase of labor in which contractions are inadequate in frequency, intensity, and duration and are ineffective in causing cervical dilation, effacement, or fetal descent.

What are hypotonic contractions?

Hypotonic uterine contraction ( inertia ): Hypotonic labour is defined as less than 3 contractions of mild to moderate intensity occurring in a 10 minute period during the active phase of labour.

What are some examples of hypertonic solutions?

Here are a few examples: Saline solution, or a solution that contains salts, is hypertonic. A solution of 5% dextrose (sugar) and 0.45% sodium chloride is an example of a hypertonic solution – so is a solution of 5% dextrose and 0.9% sodium chloride.

What does hypertonic hypotonic and isotonic mean?

Hypotonic means a lower concentration of solute (dissolved substance) compared to another solution, isotonic means about the same, and hypertonic means a higher concentration. For example, fresh water is hypotonic to seawater, the cytoplasm in human blood cells is isotonic to blood plasma, and sugar water is hypertonic to pure water.
