Involution uterus how long

Conclusions: in cases of vaginal delivery the availability of prematurity and macrosomia of the fetus delays the rates of the uterine involution. The uterine involution after cesarean section is slower and unsteady, which is more conscious in re-sections. The size of the uterus decreases rapidly over the first 30 postpartum days 1st, 3rd, 10th, and 30th days ; later, the involution decreases steadily till two months postpartum.

The trends of regression in the uterine dimensions the length, the width, and the AP diameter observed over two months after childbirth are similar in both groups Figures 7 and 8.

AP decreases following the same pattern as with other parameters of the uterus during the entire involution period in both points of both the groups Figures 9 and The 10th postpartum day is a special time for the uterine involution given the occurrence of dramatic changes in the uterine cavity during the normal puerperium experienced by both groups of women. It is important to assess these changes in terms of uterine physiology. The differences found in the endometrial cavity changes over the uterus involution period between primiparous and multiparous subjects showed no statistically significant difference; however, the difference observed on the 10th postpartum day was statistically significant in primiparous women 9.

The uterine angle deviation, in relation to the longitudinal axis of the body, changes from a particularly retroverted position to a more anteverted one. The differences found between primiparous and multiparous women are not statistically significant, but the angle changes are likely to be increasingly larger during puerperium in multiparous women median difference from the first to the 60th day is The uterine artery flow examination and index RI measurements showed significant changes in both groups until midpuerperium.

The resistance RI of the uterine artery was low immediately after childbirth and showed a significant increase one month after parturition in both groups Figure 12 ; later, these changes tend to be more steady.

The largest RI difference recorded in primiparous and multiparous women was within the first 10 postpartum days, while at the end of puerperium, no resistance differences were recorded Table 4. Notching of the uterine artery Figure 13 undergoes changes during puerperium; however, the appearance of the diastolic notch is observed not in all women even after two postpartum months Figure Unfortunately, no relevant correlations were found.

The uterine involution starts immediately after the delivery of placenta [ 24 ]. Understanding of normal view of the uterus during the entire period of puerperium helps practitioners to avoid unnecessary interventions for alleged retained products of conception RPOC or atonic uterus [ 6 — 8 , 16 ].

During the normal puerperium period, the uterine involution is defined by the changing indices of the uterine size, the uterine cavity inserts, and the uterine artery flow [ 1 — 5 , 15 ]. Until recently, there were no studies showing a view of the uterus immediately after childbirth. Most of the studies publish the first ultrasound examination findings on the 1st, 2nd, and 3rd postpartum days [ 1 , 4 , 11 — 13 ], but there is not a single ultrasound study examining the uterus within the first two hours after delivery.

The strengths of this study are as follows: the research, from the beginning to the end, was conducted by one person; the same person assisted the women under analysis during delivery; the first data are obtained from the earliest puerperium within two hours after delivery ; a detailed explanation of the differences observed between primiparous and multiparous women is provided.

The information obtained from the findings of this study on the uterus view over this period is highly efficient in postpartum hemorrhage cases. Nowadays, the doctor can bring a portable ultrasound machine to the delivery room and examine the uterus for RPOC. If we see no RPOC, we can use conservative measures for treatment without any interventions. The knowledge acquired on the physiological differences occurring between primiparous and multiparous females over the puerperium period facilitates differentiating a normal uterine contraction from an inadequate one in case of atonic uterus [ 1 , 24 ].

The findings of this study showed that although the multiparous uterus shrinks more intensively [ 25 , 26 ], it still remains of a larger size from the very early till the late puerperium. Most of the authors [ 1 — 5 ], except for one who represents the newest studies [ 9 ], show no correlation between the involution of the uterus and parity.

This study shows the differences observed in the uterus size of primiparous and multiparous women. Statistically significant bigger AP and uterus width in multiparous than primiparous women were found within one month after childbirth. Other parameters revealed that the uterine size tends to be larger in the multiparous, yet no significant differences were found.

We recommend that AP is measured in the widest part of the longitudinal view of the uterus in the same way a nonpregnant uterus is measured [ 3 — 5 , 15 — 20 ]. This study is intended to draw attention to the 10th day, when the diagnosis of the retained products of conception RPOC could be made by mistake due to a special view of the uterine cavity.

All of the women involved in the study both groups complained of the increased vaginal bleeding on the 10th—14th postpartum days, especially after physical exertion or more frequent breastfeeding, and the ultrasound findings show mostly fluid insertion of the uterine cavity in both groups at this period.

The same trend was found by other authors [ 1 , 4 , 5 ]; however, they did not find any correlation between the uterine cavity and parity.

Our study found statistically significant larger width of uterine cavity in multiparous women. Thus, this period of involution should be kept in mind by practitioners seeking to distinguish the physiological and pathological changes, especially in multiparous women. With reference to the results obtained from our study and supported by other authors, the RI of the uterine artery between the 3rd and 10th postpartum days showed a slight increase, while at the end of the 1st-month postpartum, it increased significantly.

In both groups of women, these indices are continuously increasing over a period of time from the 30th till the 42nd day Figure 12 and remain stable from 6 till to 8 weeks after labour, in contrast with other uterine parameters that are continuously changing uterine length, width, and AP diameter [ 1 , 7 , 12 — 14 , 22 ]. Unlike many authors, this study found statistically significant differences between primiparous and multiparous women taking into account the uterine artery flow indices at the first two postpartum hours, yet, opposite to Guedes-Martins et al.

At the end of the puerperium period, the RI data is almost identical in both groups. Notching of the uterine artery is one of the indices of the uterine involution changes [ 1 , 2 , 6 , 7 , 13 , 14 ] during puerperium, but an absent diastolic notch cannot be a negative indicator of involution, because even two months after labour a diastolic notch does not appear in all women Figure 14 [ 27 ]. On the 1st day within two hours after labour , the diastolic notch was absent in all of the observed women from both groups; some authors count 13— We found a more frequent notching in multiparous women on the 3rd and 30th days; however, on other days, notching appearance is higher in primiparous women.

Our findings can be different from other authors because of the sample size and different inclusion and exclusion criteria, used by other studies [ 1 — 3 , 7 , 9 ]. Advance in medical knowledge and experience facilitates a more detailed analysis of the uterine involution and a longitudinal sonographic study carried out immediately after childbirth is the best way to achieve this.

Postpartum ultrasound scan of the uterus is not only safe but also the best way of differential diagnosis of postpartum hemorrhage. The puerperium period after normal labour is dependent on parity. The most intensive uterine involution period is the first month after delivery. The trend of involution in primiparous and multiparous women is similar; however, in multiparous women, it lasts longer than 6—8 weeks.

This study speaks for longer duration of physiological uterine size and vascular return from pregnant to nonpregnant state. Also, it is important to apply this approach seeking an early detection of postpartum uterine complications.

Peripartum Cardiomyopathy Peripartum cardiomyopathy may appear in the last month of pregnancy, but it more commonly occurs within the first 5 months postpartum. Risk factors include increased age, black race, multiple gestation, and preeclampsia.

Although presenting symptoms are typical of heart failure dyspnea, fatigue, and edema , these may be subtle and are easily missed unless the myopathy is florid. Failure may lead to findings of rales, an audible third heart sound, peripheral edema, and jugular venous distention. Cardiomegaly will be evident on chest x-ray, but is likely to be underdiagnosed because films may be portable and of suboptimal quality and because there is a mild degree of cardiomegaly associated with pregnancy.

An electrocardiogram may be completely normal or may include changes consistent with left ventricular hypertrophy, bundle branch block, or arrhythmias. The echocardiogram is the test of choice, and it will show left heart dilatation, hypodynamic wall motion, and possibly, ventricular thrombi.

To be classified as peripartum cardiomyopathy, the condition must be idiopathic and limited to the timeframe noted previously. Treatment is similar to that for any heart failure and is aimed at controlling afterload through sodium restriction and diuretics and controlling rhythm with digitalization.

If thrombi are present, anticoagulation is also required. About half of these patients will have complete resolution with appropriate therapy, usually within 6 months.

Future pregnancies are not contraindicated in these patients, but recurrence is not unusual. Postpartum Depression Postpartum depression has been the subject of many monographs, book chapters, research studies, and media blitzes. Although not qualitatively different from any other major depressive episode, it is described with a separate specifier in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders.

Most women experience some period of transient depressed mood within the 1st week of delivery, referred to as postpartum blues. This may represent a combination of physical exhaustion, an overwhelming sense of the responsibilities of parenthood, and massive hormonal and metabolic shifts.

For most parturients, this period is brief days to a week and unnerving but manageable. Some patients, however, continue down the slope to feelings of despair, gross inadequacy, isolation, and depersonalization. In some cases, this can become a psychotic condition, leading to suicide or homicide.

Even at considerably less than these extremes, postpartum depression can be quite debilitating. Early identification is paramount in providing effective intervention.

Patients at particularly high risk for postpartum depression include those with a past history of depression, with complicated or extremely high-risk pregnancies, with poor social supports, and with particularly unrealistic initial expectations of motherhood. Patients often do not volunteer their depressed emotion, and even direct inquiry may be unrevealing if the patient is highly socially responsive.

A standardized screening tool such as the Edinburgh Postpartum Depression Scale 42 or the Beck Depression Inventory 43 can easily be incorporated into a 1- or 2-week phone call or 2- or 3-week follow-up visit protocol to allow thorough screening for this common and potentially devastating condition. The postpartum period is one of rapid and then gradual resolution of most of the changes of pregnancy back to the prepregnant condition.

Whereas these changes are physiologic, much like pregnancy itself, there remains a great deal of biologic hazard in traversing this territory. Caregivers and community have focused heavily on the delivery and the baby and have tended to neglect the puerperium as an area worthy of attention.

Consequently, many complications go unnoticed altogether or are identified late. A wise practitioner will maintain a consistent personal algorithm for routine care of the parturient and an aggressive differential diagnosis of complaints lodged during this time.

Effective screening practices along with a high index of suspicion will go a long way in providing a smooth return of the parturient to whatever degree of normalcy a new mother will achieve.
