Clinical experience with patients suffering from hyperemesis gravidarum (severe nausea and vomiting during pregnancy): thoughts about subtyping of patients, treatment and counseling models

"Which baby?": a qualitative study exploring the fantasies about the unborn baby among women with hyperemesis gravidarum

This study aims to explore the conscious fantasies about the unborn baby among women experiencing hyperemesis gravidarum and identify possible clinical implications. Fourteen inpatient women with moderate to severe symptoms of hyperemesis gravidarum and between the 12 and 14 weeks gestation participated in semi-structured interviews. Analysis of the transcripts revealed escape and aggression fantasies about the baby, denial of fantasies in the categories tested (name, sex, external and internal characteristics of the baby), freezing of the maternal-fetus bond, and ambivalence toward the continuation of the pregnancy. Neither the severity of symptoms nor the stated quality of life mediated the results. These findings suggest that the discussion and reframing of fantasies can be proven helpful and relieving for the women facing any pregnancy complication. Toward achieving a multidisciplinary approach, the variable of fantasy should be considered among others.

Pregnancy health problems and low birth weight associated with maternal insecure attachment style

We aimed to determine the association between attachment style and health problems during pregnancy, as well as perinatal health variables. In 122 mothers who were 2–18 months postpartum, hot flushes, vaginal discharge, back pain, breast tenderness, hair changes, and psychological problems were shown to be associated with insecure attachment as measured by the Adult Attachment Style Questionnaires. Babies born to mothers with insecure attachment were more likely to have a low birth weight. It is vital to increase awareness of insecure attachment style as a risk factor among perinatal health care providers to optimize services.

Hyperemesis gravidarum and risks of placental dysfunction disorders: a population-based cohort study

Objective

To study whether pregnancies complicated by hyperemesis gravidarum in the first (<12 weeks) or second (12–21 weeks) trimester are associated with placental dysfunction disorders.

Design

Population-based cohort study.

Setting

Sweden.

Population

All pregnancies in the Swedish Medical Birth Register estimated to have started on 1 January 1997 or later and ended in a single birth on 31 December 2009 or earlier (n = 1 156 050).

Methods

Odds ratios with 95% confidence intervals were estimated for placental dysfunction disorders in women with an inpatient diagnosis of hyperemesis gravidarum, using women without inpatient diagnosis of hyperemesis gravidarum as reference. Risks were adjusted for maternal age, parity, body mass index, height, smoking, cohabitation with the infant's father, infant's sex, mother's country of birth, education, presence of hyperthyreosis, pregestational diabetes mellitus, chronic hypertension and year of infant birth.

Main outcome measures

Placental dysfunction disorders, i.e. pre-eclampsia, placental abruption, stillbirth and small for gestational age (SGA).

Results

Women with hyperemesis gravidarum in the first trimester had only a slightly increased risk of pre-eclampsia. Women with hyperemesis gravidarum with first admission in the second trimester had a more than doubled risk of preterm (<37 weeks) pre-eclampsia, a threefold increased risk of placental abruption and a 39% increased risk of an SGA birth (adjusted odds ratios [95% confidence intervals] were: 2.09 [1.38–3.16], 3.07 [1.88–5.00] and 1.39 [1.06–1.83], respectively).

Conclusions

There is an association between hyperemesis gravidarum and placental dysfunction disorders, which is especially strong for women with hyperemesis gravidarum in the second trimester.

Nursing Care of Nausea and Vomiting in Pregnancy

Nursing theories and conceptual models need to be developed and used in practice for accumulation of nursing knowledge. The authors in this article explain the concepts and nursing process of the Roy adaptation model in light of an example with the nausea and vomiting of pregnancy. It is expected that the article will provide guidance for nurses who want to use the model while offering nursing care and conducting research.

Hyperemesis gravidarum and fetal outcome

BACKGROUND

Hyperemesis gravidarum (HG) is reported in 0.5-2% of all pregnancies. The purpose of this research was to evaluate the relationship of maternal HG, neonatal birth weight, and birth outcomes.

METHODS

This is a prospective cohort study of 45 patients diagnosed, by Fairweather's criteria, with HG compared with 306 non-HG control pregnant patients with singleton pregnancies. Sociodemographic and clinical data were obtained from the pregnant patients. Neonatal data were also collected, including indicators of neonatal wellness.

RESULTS

Significantly higher incidences of being nonwhite (33% vs 16%; p < .05) and of attaining post-high school education (60% vs 38%) were noted in the HG group, relative to controls. Mothers in the control group experienced greater gestational weight gain, 14.9 +/- 0.3 kg (mean +/- SEM) relative to mothers in the HG group (10.6 +/- 1.3 kg). Infants from HG pregnancies manifested significantly lower birth weight (3.23 +/- 0.09 kg vs 3.52 +/- 0.03 kg), younger gestational age (38.4 +/- 0.3 weeks vs 39.7 +/- 0.1 weeks), and a greater length of hospital stay (2.9 +/- 0.5 days vs 1.8 +/- 0.1 day), relative to infants from the control group. After undergoing multivariate analysis, HG was a significant predictor of decreased gestational age and increased hospital length of stay.

CONCLUSIONS

Infants born of women who had HG are more likely to experience decreased gestational age and increased length of hospital stay. Efficacy of early and aggressive treatment of HG, including nutrition support, in minimizing these outcomes needs to be studied.

Hyperemesis gravidarum, a literature review

Hyperemesis gravidarum (HG) is a condition causing severe nausea and vomiting in early pregnancy often resulting in hospital admission. The incidence of HG is approximately 0.5% of live births, said to be higher in multiple pregnancies, hydatidiform mole and other conditions associated with increased pregnancy hormone levels. Both the aetiology and pathogenesis of HG remain unknown. We conducted a literature review (1966-now) to summarize the current evidence on the aetiology and pathogenesis of HG. The potential role of pregnancy-related hormones such as progesterone, estrogen and HCG has been widely studied; however, various other hormones such as leptin, placental growth hormone, prolactin, thyroid and adrenal cortical hormones have been implicated in the aetiology of HG. In addition to endocrinological hypotheses, the rationale and evidence considering infectious, immunological, psychological, metabolic and anatomical causes for HG have been analysed here. Many studies suffer from the low number of patients included, the variable definition used for HG and varying assay methodology used in studies of hormone measurement. This review highlights the need for more extensive studies addressing the pathogenesis and aetiology of HG.

The Impact of Hyperemesis Gravidarum on Maternal Role Assumption

OBJECTIVES

To describe what it is like to have hyperemesis gravidarum and explore its impact on the assumption of the maternal role during the perinatal period.

DESIGN

Qualitative descriptive design.

PARTICIPANTS

Eight women who had been diagnosed with hyperemesis gravidarum were recruited through private prenatal clinics using a snowball technique. Participants were interviewed about their experiences with hyperemesis gravidarum in their homes or other suitable sites selected by them.

MAIN OUTCOME MEASURES

Transcribed interviews were analyzed using grounded theory methodology. A core category and subcategories were determined.

RESULTS

Hyperemesis gravidarum is a disorder that alters the usual response to pregnancy and birth. Participants in this study described it as so debilitating that they had little concern for anything else, including the fetus. After symptoms subsided, the participants reported that they were able to regain control over their lives and made an effort to make up for lost time in becoming attached to the baby.

CONCLUSION

Women suffering from hyperemesis gravidarum may not benefit from the usual prenatal education efforts. Additional support following delivery may be needed as the woman attaches to her infant and learns to provide care.

Psychological health in early pregnancy: relationship with nausea and vomiting

The psychological health of women in early pregnancy was investigated in a sample of 273 women (mean gestational age 12.8 weeks, SD=2.8) using the General Health Questionnaire (GHQ) and mood and illness perception visual analogue scales, and compared with the prevalence and severity of nausea and vomiting as measured using the Nausea and Vomiting in Pregnancy Instrument (NVPI). Using a cut-off of 4/5 for the GHQ, 50.5% of pregnant women were found to have potential psychiatric problems. However, perceived mental health and physical illness was significantly better than anticipated. The severity of nausea and vomiting correlated independently with GHQ subscales for somatic symptoms, social dysfunction, anxiety/insomnia and severe depression. The contradiction between high GHQ scored and high perceived wellbeing might be explained through cognitive processing. Nausea and vomiting in early pregnancy is associated with psychiatric morbidity. The causal relationship between the two conditions has not been established.

Chicken or the egg? The biological-psychological controversy surrounding hyperemesis gravidarum

Women's somatic complaints are more likely to be labeled by physicians and other health care professionals as psychologically based when the condition has an obscure etiology. Perhaps because of this, there are a number of medical conditions which have been under investigated and where erroneous assumptions about them exist. Hyperemesis gravidarum (HG)--severe nausea and vomiting during pregnancy--is an example of such an illness. HG remains a puzzling condition for both physicians and patients because there is no known cause or cure. By its very nature, HG has a clearly established biological cause--pregnancy. Yet, because the exact causal pathophysiological mechanism is unknown, the organicity of the pregnant state is either minimized or ignored. This paper examines how HG is characterized in the literature and the empirical basis for psychogenesis. Analysis of the literature reveals a tension in the discourse such that both biologic and psychologic approaches to HG have existed in parallel tracks throughout history. Still, results support that sociocultural factors rather than scientific evidence have shaped the overarching and predominant illness paradigm of psychogenesis. Implications for women's health care and HG, in particular, are presented.
