Clinical manifestations and treatment measures of uterine atony

Clinical manifestations and treatment measures of uterine atony

We all know that the main force of labor is uterine contraction, which runs through the entire process of delivery. If during the delivery process, the rhythm, symmetry and polarity of uterine contractions are abnormal, or the intensity and frequency change, it will affect delivery and even cause fetal death. This phenomenon is medically known as uterine atony. So what are the specific manifestations of uterine atony? How should it be treated medically?

Clinical manifestations

1. The uterine contractions are weak, with long intervals and short durations. When the contractions are strongest, depression will appear on the uterine wall when pressed with finger pressure.

2. Labor progresses slowly.

3. Poor rest, mental and physical fatigue, dehydration and acidosis.

Diagnosis

1. The uterine contraction is weak and powerless, and the labor process is long.

2. Primary uterine atony refers to the uterine contraction weakness that occurs at the beginning of labor.

3. Secondary uterine atony refers to the onset of uterine atony at a certain stage in the labor process.

4. The intrauterine pressure is less than 4KPA.

Treatment principles

1. Exclude birth canal and fetal dystocia and determine the mode of delivery.

2. It can enhance the physical strength of mothers who give birth vaginally and strengthen uterine contractions.

3. If there is cephalopelvic disproportion or fetal distress, surgery should be performed as soon as possible.

4. Prevent postpartum hemorrhage and infection after the condition improves.

Medication principles

1. If the fetal membranes have not ruptured and the cervix is ​​dilated less than 3 cm, it is advisable to first use warm soapy water enema and then perform artificial rupture of membranes after defecation.

2. If the above treatment is ineffective or secondary uterine atony occurs, vitamin B1 acupuncture injection and oxytocin intravenous drip can be used.

3. Those who are mentally stressed and physically weak should be given rest and, if necessary, be given pethidine or diazepam to strengthen uterine contractions.

4. Those who eat less and are dehydrated should replenish fluids as appropriate.
