Maternal pain and anxiety in genetic amniocentesis: expectation versus reality

The effect of watching an informational video prior amniocentesis on maternal anxiety: a randomized controlled trail

PURPOSE

This randomized controlled trial aimed to ascertain the effect of a pre-procedure informational video on anxiety, pain perception, and satisfaction levels in patients undergoing amniocentesis.

METHODS

Patients were randomized into two groups: a video group who watched an informational video prior to the procedure, and a control group who received standard care. Anxiety was gauged both pre- and post-procedure via the State-Trait Anxiety Inventory (STAI) score. Post-procedure, patients' perceived pain, anxiety, and satisfaction levels were evaluated using the Visual Analog Scale questionnaire (VAS).

RESULTS

Of 110 randomized patients, 100 completed the study and were included in the final analysis. No significant difference was noted in overall anxiety levels between the study and control groups. However, in-procedure anxiety was significantly lower in the video group compared to the control group (p = 0.04). Among patients undergoing amniocentesis for the first time, the subgroup analysis revealed reduced levels of anxiety during the procedure and diminished pain 10 min after the procedure in the video group compared to the control group. (p = 0.041 and p = 0.025, respectively).

CONCLUSION

A pre-procedural informational video could help in alleviating anxiety and mitigating pain during amniocentesis.

CLINICAL TRIAL REGISTRATION

An evaluation of newborn hearing screening brochures and parental understanding of screening result terminology

OBJECTIVE

To assess the suitability of newborn hearing screening brochures by evaluating current state-level brochures and pregnant people's understanding of screening result terminology.

DESIGN

In Study 1, state-level brochures were evaluated based on readability, design, picture appropriateness, and use of the word "refer." In Study 2, pregnant people completed a questionnaire that queried their understanding of and expected anxiety about three newborn hearing screening outcomes ("refer," "did not pass," and "pass").

STUDY SAMPLE

In Study 1, 59 newborn hearing screening brochures were analysed. In Study 2, 43 pregnant people completed surveys during a prenatal appointment.

RESULTS

Most of the brochures were found deficient on at least one element. Thirty percent of brochures used the word "refer" to indicate a hearing screening failure; yet, fewer than half of participants understood its meaning. Ratings of expected anxiety were highest in response to the term "did not pass."

CONCLUSIONS

Based on four study criteria of brochure suitability, 88% of available state-level newborn hearing screening brochures should be modified to make them readily understandable by a broad educational demographic. Discretion in use of the term "refer" should be made when indicating screening results, because the term is not readily understood.

Cold therapy for pain relief during and after amniocentesis procedure: A randomized controlled trial

AIM

To compare effects of cold therapy on patient pain score during and after amniocentesis procedure.

METHODS

We performed a prospective randomized-controlled study comparing the anticipated pain, perceived pain during the procedure, and pain after 15 and 30 min of amniocentesis between pregnant women receiving cold therapy before (group 1), after (group 2), and both before and after amniocentesis (group 3) with a control group (group 4). Pain was measured using a visual analog scale (VAS) score.

RESULTS

A total of 480 participants were recruited and randomly assigned into four groups of 120 each. Anticipated pain scores in all groups were not statistically different. When compared with group 4, groups 1 and 3 experienced significant pain reduction during amniocentesis, while VAS scores at 15 and 30 min after amniocentesis in groups 1-3 were significantly lower as compared to group 4.

CONCLUSION

Cold therapy both before and after amniocentesis procedure is most effective in pain reduction. It encourages the pregnant woman's cooperation during the procedure and provides a good amniocentesis experience. Application of cold compression is also beneficial in other aspects as it is simple, safe, convenient, and yet reusable and economically efficient for routine use in all pregnant women undergoing amniocentesis.

Analgesic efficacy of virtual reality for acute pain in amniocentesis: A randomized controlled trial

BACKGROUND

To evaluate the efficacy of virtual reality (VR) as a distraction technique in the management of acute pain and anxiety during amniocentesis.

STUDY DESIGN

A randomized controlled trial was conducted between September 2020 and October 2020 involving 60 women undergoing mid-trimester amniocentesis. Thirty women were assigned randomly to the VR intervention (immersive video content as a distraction method) group and 30 to the standard care group using a predetermined randomization code. The primary outcome measure was the visual analog scale (VAS) pain score, along with the women's ratings of their extent of anxiety experienced during the procedure. The VAS consisted of a 10 cm line ranging from 0 to 10 (anchored by 0 = no pain and 10=very severe pain). Anxiety was assessed on Spielberger's state-trait anxiety inventory (STAI) questionnaire.

RESULTS

The patients' characteristics and obstetric data were similar in both groups. The ratings on the VAS indicated that the VR intervention was associated with significantly less pain than the ratings in the standard of care group; namely, 2.5 ± 1.5 vs. 3.8 ± 1.7, respectively (95 % CI 0.44-2.13; p = 0.003). There were no significant differences in maternal anxiety levels before and after amniocentesis.

CONCLUSION

The VR intervention as a distractive technique emerged as effective in reducing pain during amniocentesis. It is easy to use, relatively inexpensive, has the advantage of no serious side effects, and may decrease the fear of pain that can affect patients' experiences and compliance with this procedure.

The impact of invasive prenatal testing on anxiety and sleep quality in pregnant women with a screen-positive result for aneuploidy

PURPOSE

Prenatal anxiety has negative effects on pregnancy and neonate. Both screening tests and invasive diagnostic tests are associated with elevated anxiety level. But a normal fetal karyotype result could improve the anxiety level in high-risk patients. We hypothesized that patients who prefer follow-up without karyotyping may experience increased anxiety and sleep impairment until delivery. Our aim was to determine the effect of invasive diagnostic test decision on anxiety and sleep quality in women with a positive screening result.

METHODS

132 women were included for the study and three groups were described. The invasive group consisted of women who underwent invasive procedure after a screen-positive test result, the follow-up group consisted of women who preferred non-invasive follow-up after a screen-positive result and the control group consisted of women with screen-negative test results. Participants were evaluated with the State-Trait Anxiety Inventory (STAI) and the Pittsburgh Sleep Quality Index (PSQI) after genetic counseling. They were asked for completing the same questionnaires in the third trimester to establish the course of anxiety and sleep quality throughout pregnancy.

RESULTS

STAI scores were significantly higher in both screen-positive groups than in the control group in the first evaluation (p < 0.001). STAI scores decreased in the invasive group and controls while PSQI scores did not significantly change during the course of the pregnancy. However, the anxiety level and sleep quality were worsened over time in the follow-up group.

CONCLUSION

Screen-positive women who preferred to follow up had higher anxiety level and worse sleep quality in the later stages of pregnancy. We concluded that invasive prenatal diagnostic tests could improve anxiety and sleep quality in pregnant women with a screen-positive result for aneuploidy.

Pain perception during transabdominal chorionic villus sampling: a randomized trial comparing topical ethyl chloride anesthetic spray and lidocaine injection

Background: Chorionic villus sampling is an important invasive procedure used for early antenatal genetic testing that can be associated with anxiety and fear of pain. Pain analgesia prior to chorionic villus sampling can be offered with subdermal lidocaine; however, lidocaine injection itself is associated with pain. Our objective was to determine whether administration of topical ethyl chloride anesthetic spray is associated with decreased pain perception during transabdominal chorionic villus sampling compared to 1% lidocaine subdermal injection.Study design: Women undergoing transabdominal chorionic villus sampling from 10 to 13 weeks and 6 days in an outpatient setting were randomized with equal allocation to either 1% lidocaine injection or topical ethyl chloride anesthetic spray prior to the procedure. Women were asked about their pain on a scale of 0-100 prior to, during, and after the procedure. The primary outcome was pain perception during time of transabdominal chorionic villus sampling as measured on a 100-mm visual analog scale. The secondary outcome was pain immediately after procedure.Results: From October 2016 to June 2017, a total of 120 women were enrolled (63 in the lidocaine injection group and 57 in the topical ethyl chloride anesthetic spray group). Baseline demographic characteristics were similar between groups. During the procedure, patients in the topical ethyl chloride arm demonstrated significantly higher pain scores compared to the lidocaine injection group (median score of 50 mm (interquartile range [IQR]: 40-65) versus 50 mm (IQR: 30-60); p = .03). There was no significant difference in pain scores before or after the procedure.Conclusion: During transabdominal chorionic villus sampling procedures, topical ethyl chloride anesthetic spray is associated with a higher distribution of pain scores as compared to 1% lidocaine subdermal injection, which suggests higher levels of pain.Clinical trial registration: This trial is registered with clinicaltrials.gov (NCT03140293). https://clinicaltrials.gov/ct2/show/NCT03140293?term=NCT03140293&rank=1.

Maternal anxiety and its correlation with pain experience during chorion villus sampling and amniocentesis

PURPOSE

Invasive prenatal diagnostic procedures, such as chorion villus sampling (CVS) and amniocentesis (AC), are routinely performed to exclude or diagnose fetal chromosomal abnormalities. The aim of this study was to investigate anxiety-dependent pain experience during CVS and AC and the potential factors that increase anxiety and pain levels.

PATIENTS AND METHODS

During a 2-year period, women undergoing invasive procedures in three specialist centers were asked to participate in the study. Anxiety was evaluated before the procedure using the Spielberger State-Trait-Anxiety-Inventory, and pain was evaluated directly after the procedure using a verbal rating scale.

RESULTS

Among the women, 348/480 (73%) underwent AC, while 131/480 (27%) underwent CVS. There was a significant correlation between state and trait anxiety (p<0.0001). A positive correlation existed between the degree of anxiety and the level of pain experienced (p=0.01). There was a positive correlation for trait anxiety (p=0.0283) as well as for state anxiety (p=0.0001) and pain perception (p=0.0061) when invasive procedure was performed owing to abnormal ultrasound finding or to a history of fetal aneuploidy. Maternal age was found to be another influencing factor for the experienced pain (p=0.0016). Furthermore, the analysis showed a significant negative correlation between maternal age and anxiety. That applies for trait anxiety (p=0.0001) as well as for state anxiety (p=0.0001). The older the woman, the less anxious the reported feeling was in both groups. The main indication for undergoing CVS was abnormal ultrasound results (45%), and the main reason for undergoing AC was maternal age (58%).

CONCLUSION

Procedure-related pain intensity is highly dependent on the degree of anxiety before the invasive procedure. In addition, the indication has a significant impact on the emerging anxiety and consequential pain experiences. These influencing factors should therefore be considered during counseling and performance.

Non-invasive prenatal testing: ethics and policy considerations

New technologies analyzing fetal DNA in maternal blood have led to the wide commercial availability of non-invasive prenatal testing (NIPT). We present here for clinicians the ethical and policy issues related to an emerging practice option. Although NIPT presents opportunities for pregnant women, particularly women who are at increased risk of having a baby with an abnormality or who are otherwise likely to access invasive prenatal testing, NIPT brings significant ethics and policy challenges. The ethical issues include multiple aspects of informed decision-making, such as access to counselling about the possible results of the test in advance of making a decision about participation in NIPT. Policy considerations include issues related to offering and promoting a privately available medical strategy in publicly funded institutions. Ethics and policy considerations merge in NIPT with regard to sex selection and support for persons living with disabilities.

Development and validation of the Prenatal Diagnostic Procedures Anxiety Scale

OBJECTIVES

As there are currently no specific measures of anxiety due to prenatal diagnostic procedures, the aim of the study was to develop and validate a new measure called the Prenatal Diagnostic Procedure Anxiety Scale (PDPAS).

METHODS

Seventy-four pregnant women scheduled for amniocentesis and ultrasound completed the PDPAS, the State-Trait Anxiety Inventory, the Edinburgh Postnatal Depression Scale, and the Perceived Stress Scale before undergoing the diagnostic procedure. Reliability, concurrent validity, factor structure, scale sensitivity, and specificity were analyzed. Differences between amniocentesis and ultrasound groups in the PDPAS score were analyzed with a t-test.

RESULTS

The final scale comprised 11 items and two subscales measuring 'fear of procedure' and 'fear of abnormal result'. Concurrent validity analysis showed that the PDPAS is an independent measure of anxiety. At a cut-off score of >11, sensitivity was 75.0% and specificity was 72.01% with moderate accuracy. Fear of procedure was higher in the amniocentesis group, whereas fear of abnormal result was equally present in both amniocentesis and ultrasound groups.

CONCLUSION

The PDPAS has good internal consistency and concurrent validity with satisfactory psychometric characteristics. As a short measure of situation-specific anxiety, it can be used as a screening tool in prenatal clinical settings.

The association between perceived emotional support, maternal mood, salivary cortisol, salivary cortisone, and the ratio between the two compounds in response to acute stress in second trimester pregnant women

OBJECTIVE

Little is known about the effect of social support on the reactivity of the hypothalamic-pituitary-adrenal (HPA) axis during pregnancy. Moreover, when investigating the HPA axis most studies do not consider the activity of 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2), an enzyme within the salivary glands that inactivates cortisol to cortisone. This study explores the association between perceived emotional support and the maternal psychobiological stress response to a standardized naturalistic stressor by assessing maternal mood and the reactivity of salivary cortisol (SalF), salivary cortisone (SalE), and the SalE/(E+F) ratio as a marker of 11β-HSD2 activity.

METHODS

Repeated saliva samples and measures of maternal mood were obtained from 34 healthy second trimester pregnant women undergoing amniocentesis which served as a psychological stressor. The pregnant women additionally responded to a questionnaire of perceived emotional support and provided sociodemographic (e.g., maternal educational degree) and pregnancy-specific data (e.g., planned versus unplanned pregnancy).

RESULTS

Perceived emotional support neither showed a significant effect on mood nor on the SalF or SalE response to stress. However, a moderately strong positive association was found between perceived emotional support and SalE/(E+F) (r=.49). Additionally, the final regression analysis revealed a significant negative relationship between educational degree, planned/unplanned pregnancy and SalE/(E+F).

CONCLUSION

Findings suggest a higher metabolization of cortisol to cortisone in pregnant women with higher emotional support. In contrast, higher maternal education and unplanned pregnancy appear to be associated with decreased salivary 11β-HSD2 activity. The current study emphasizes the importance of taking the activity of 11β-HSD2 into account when examining SalF.

The psychological effects of prenatal diagnostic procedures: maternal anxiety before and after invasive and noninvasive procedures

OBJECTIVES

(1) To examine the change in anxiety before and after prenatal diagnostic procedures in women undergoing invasive (amniocentesis) and noninvasive (ultrasound) procedures; and (2) to examine predictors of anxiety before the diagnostic procedure.

METHODS

A short-term follow-up study was conducted on a sample of pregnant women in the second trimester. Questionnaires were administered to women scheduled for amniocentesis (n = 37) and ultrasonography (n = 37) before and immediately after the procedure. The following questionnaires were administered: the State-Trait Anxiety Inventory, the Affect Intensity Measure, the COPE inventory, and the Optimism-Pessimism Scale.

RESULTS

Prior to the administration of the prenatal diagnostic procedure, measured anxiety levels were the same in both groups of women (p > 0.05). An interaction effect of a two-way ANOVA revealed that anxiety decreased after the procedure in the ultrasound but not the amniocentesis group (F(1, 72) = 5.01, p = 0.028). Although coping styles and affect intensity were found to be related to anxiety (p < 0.05), they were not significant predictors of anxiety before the diagnostic procedure when controlling for trait anxiety and procedure type.

CONCLUSION

Anxiety levels associated with noninvasive but not after invasive, prenatal diagnostics tests decrease immediately following the procedure.

Maternal anxiety and pain during prenatal diagnostic techniques: a prospective study

OBJECTIVE

To explore anxiety and pain felt by women undergoing chorionic villus sampling (CVS) and amniocentesis (AC).

METHOD

We prospectively questioned 254 women (67 undergoing CVS, 187 AC) before the procedure on their anxiety, after the procedure on their pain felt, and the support they received or desired. The medical team collected technical information concerning each procedure.

RESULTS

The level of anxiety was significantly higher in women undergoing CVS than AC, in those who had received complete information before the procedure, and when indication for the procedure was fetal structural abnormalities. The level of pain was significantly higher in cases of anxious women, those undergoing a CVS rather than AC, those who had undergone invasive prenatal diagnostic procedures in previous pregnancies, in procedures deemed difficult by the operator, and with needle insertion in the lateral part of the uterus. About 30% of women undergoing CVS and 8% of those undergoing AC would have desired some form of pain prevention, mostly with nonpharmacologic therapy.

CONCLUSION

Prenatal diagnosis is frequently associated with anxiety and pain. We identified factors that could exacerbate either one. When questioned, patients would desire a nonpharmacologic means for pain prevention.

Analgesia for amniocentesis or chorionic villus sampling

BACKGROUND

Besides risks of miscarriage, pregnant women undergoing amniocentesis or chorionic villus sampling (CVS) are also concerned about pain associated with these procedures. Currently, approaches to analgesia can be categorised in two broad categories - non-pharmacological and pharmacological agents.

OBJECTIVES

To evaluate whether different methods of analgesia have any impact on pain reduction during amniocentesis or chorionic villus sampling (CVS).

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2011).

SELECTION CRITERIA

All randomised trials comparing different method of analgesia for amniocentesis or CVS. We also include trials with quasi-randomised designs, but analyse and report their results separately.

DATA COLLECTION AND ANALYSIS

Both review authors assessed eligibility and trial quality and performed data extraction.

MAIN RESULTS

We included a total of five randomised studies (involving 805 women) evaluating different methods of analgesia for amniocentesis; there were no studies in women undergoing CVS.One RCT (N = 203) and one quasi-randomised study (N = 220) compared infiltrative local anaesthesia with no anaesthesia and found no statistical difference in experienced pain on the visual analogue scale (VAS) (mean differences (MD) -2.50 and 1.20; 95% confidence interval (CI) -6.98 to 1.98 and -2.67 to 5.07).One study (N = 200) compared light leg rubbing versus no intervention during amniocentesis and found no change in experienced anxiety (MD 0.2; 95% CI -0.63 to 1.03) or VAS pain score (MD 0.3; 95% CI -0.35 to 0.95) during amniocentesis.Another study with 62 patients did not find any benefit of using subfreezing temperature needle during amniocentesis in terms of decreased VAS pain score (MD -0.8; 95% CI -1.8 to 0.2). In addition, there was no difference between anticipated and actual pain (MD 0.4; 95% CI -0.82 to 1.62) (before/after comparison).There was also no difference in VAS pain scores in the study with 120 participants comparing lidocaine-prilocaine analgesic cream to placebo cream before amniocentesis (MD -0.6; 95% CI -1.44 to 0.24).

AUTHORS' CONCLUSIONS

In general, women who undergo amniocentesis could be informed that pain during procedure is minor and that there is currently insufficient evidence to support the use of local anaesthetics, leg rubbing or subfreezing the needle for pain reduction during procedure.

Effect of pre-amniocentesis counseling on maternal pain and anxiety

AIM

The aim of this study was to evaluate the levels of anticipated and perceived pain and anxiety in expectant mothers at the times of pre-counseling, post-counseling, and post-amniocentesis and to investigate the effect of pre-amniocentesis counseling on the level of pain and anxiety.

MATERIALS AND METHODS

This prospective study was carried out on 240 women with singleton pregnancies at mid-trimester. The maternal pain and anxiety levels associated with the procedure were evaluated using the visual analogue scale. Perceived pain and anxiety were assessed before and after counseling the pregnant woman about amniocentesis, and after amniocentesis.

RESULTS

Median anticipated pain levels before (pain 1) and after pre-procedure counseling (pain 2) were 5 and 4, respectively. The actual pain after the procedure (pain 3) was 3. Median levels of anxiety felt by the patients before (anxiety 1) and after pre-procedure counseling (anxiety 2) were 6 and 3, respectively, while the median anxiety after the procedure (anxiety 3) was 5. For the pain and anxiety measurements, the results for each of the comparison times were significantly different from the results for the other two comparison times (P < 0.001).

CONCLUSION

Adequate pre-amniocentesis counseling effectively reduces the actual level of pain and anxiety felt by the mother undergoing mid-trimester amniocentesis.

Information and decision support needs of parents considering amniocentesis: interviews with pregnant women and health professionals

OBJECTIVE

Our aim was to clarify and categorize information and decision support needs of pregnant women deciding about amniocentesis.

BACKGROUND

Prenatal screening for Down's syndrome (implemented in routine practice) generates a quantifiable risk of chromosome abnormality. To increase certainty, chromosomal material needs to be obtained through amniocentesis or other diagnostic test. Amniocentesis carries risks of pregnancy loss.

METHODS

Semi-structured interviews were conducted with health professionals and pregnant women who had considered amniocentesis. The data were qualitatively analysed using a two-step thematic content analysis.

RESULTS

A sample of 17 health professionals and 17 pregnant women were interviewed. Professionals demonstrated little consensus regarding the miscarriage rate, the potential consequences of amniocentesis testing and the uncertainty associated with the tests. Furthermore, methods employed to communicate risks varied between professionals. Pregnant women reported heightened stress and anxiety. Twelve out of 17 women described the decision as complex and difficult to make while five participants were satisfied with the information and support provided. Women would have liked more information about the risks involved, the results, the consequences of an amniocentesis and associated emotional difficulties. Women highlighted the need for personalized information, presented in multiple ways, while remaining simple and unbiased.

CONCLUSIONS

There is variation in the provision of information related to amniocentesis testing. The majority of pregnant women reported difficulties making a decision and identified dimensions of information and decision support where improvements were needed.

Pain associated with chorionic villus sampling: transabdominal vs transcervical approach

OBJECTIVE

The purpose of this study was to compare anticipated and perceived pain that is associated with transabdominal and transcervical chorionic villus sampling (CVS).

STUDY DESIGN

Women with singleton pregnancies who were undergoing CVS completed a preprocedure 0-10 visual analog scale (VAS; 0 = no pain, 10 = excruciating pain) for anticipated transabdominal and transcervical CVS-related pain. After the procedure, patients completed a VAS for perceived pain.

RESULTS

One hundred twenty-one women underwent transabdominal (n = 98) or transcervical (n = 23) CVS. Anticipated pain was 4.5 +/- 2.0, which was similar in patients who ultimately underwent transabdominal (score, 4.6 +/- 3.8) or transcervical (score, 4.1 +/- 2.2) CVS. Postprocedure perceived pain was similar for transabdominal CVS in women with an abdominal wall thickness of <4 cm (score, 2.3 +/- 0.8) and transcervical CVS (score, 2.6 +/- 2.2) but was significantly greater for transabdominal CVS among women with an abdominal wall thickness of > or =4 cm (score, 5.6 +/- 1.2; P < .0001) and nulliparous women who had transcervical CVS (score, 4.3 +/- 2.1; P = .01).

CONCLUSION

Transabdominal CVS is more painful in heavier women, and transcervical CVS is more painful in nulliparous women.

Light-scattering spectroscopy differentiates fetal from adult nucleated red blood cells: may lead to noninvasive prenatal diagnosis

Present techniques for prenatal diagnosis are invasive and present significant risks of fetal loss. Noninvasive prenatal diagnosis utilizing fetal nucleated red blood cells (fNRBC) circulating in maternal peripheral blood has received attention, since it poses no risk to the fetus. However, because of the failure to find broadly applicable identifiers that can differentiate fetal from adult NRBC, reliable detection of viable fNRBC in amounts sufficient for clinical use remains a challenge. In this Letter we show that fNRBC light-scattering spectroscopic signatures may lead to a clinically useful method of minimally invasive prenatal genetic testing.

Pain experience during chorionic villus sampling and amniocentesis: A preliminary study

OBJECTIVE

To investigate the maternal perception of pain before and after amniocentesis (AC) or transabdominal chorionic villus sampling (TA-CVS).

STUDY DESIGN

Three hundred women were divided into groups of 100 participants destined to undergo three different fetal sampling procedures: amniocentesis (group 1), transabdominal chorionic villus sampling (CVS) with a 19 gauge Blache needle (group 2) and transabdominal CVS with a 20 gauge needle (group 3). The visual analog scale (VAS) was used to quantify the patient's pre-sampling expected pain level and the real pain level was measured immediately after the sampling procedure. The factors liable to influence the VAS score after the sampling procedure were studied by single and multivariate analysis and concerned either the sampling procedure or patient demographic data.

RESULTS

The VAS scores obtained before the procedure were not significantly different for the three sampling groups. When performed with a 19 gauge Blache needle TA-CVS is significantly more painful than the other sampling procedures (p=0.0002): VAS score of 3.62 (group 2), 2.49 (group 3) and 2.68 (group 1) for CVS with 20 gauge needle and amniocentesis. Multivariate analysis identified a group of patients for which the perception of pain induced by sampling was higher compared to the other patients: nulliparous patients, having undergone 19 gauge Blache needle CVS, with a high pre-sampling VAS score.

CONCLUSION

Transabdominal chorionic villus sampling with a 19 gauge Blache needle seems to be the most painful sampling procedure. We question the need to use a 19 gauge needle as acceptable results are obtained with a 20 gauge needle.

Does local anesthesia decrease pain perception in women undergoing amniocentesis?

OBJECTIVE

The null hypothesis is that local anesthesia does not decrease pain perception during amniocentesis.

STUDY DESIGN

We performed a prospective randomized study comparing local anesthesia (1% lidocaine) with no anesthesia before amniocentesis in a racially diverse population. Immediately after the procedure, subjects were asked to assess their pain using both a Visual Analogue Scale and a 101-point Numerical Rating Scale.

RESULTS

Two hundred four women were enrolled; 101 women received local, 102 women received no local, and 1 woman declined the amniocentesis after randomization. There was no difference in pain perception between the 2 groups as measured by either the visual analogue scale or the numeric rating scale (P = .28 and .18 respectively). The correlation coefficient between the 2 pain scales was strong with 0.86 for the local group and 0.92 for the no local group, (P < .001).

CONCLUSION

Administration of local anesthesia before amniocentesis does not decrease maternal pain perception.

Reducing pain with genetic amniocentesis-A randomized trial of subfreezing versus room temperature needles

OBJECTIVE

To determine whether pain associated with second trimester genetic amniocentesis is decreased by using subfreezing rather than room temperature needles.

METHODS

Subjects were randomized to a -14 degrees C or room temperature (20-22 degrees C) 22-gauge spinal needle. Patients, blinded to allocation, recorded anticipated and actual pain before and after the procedure, respectively, using a 0-10 visual analog scale with 0 = no pain and 10 = excruciating pain.

RESULTS

Thirty-three subjects were randomized to room temperature and 29 subjects to subfreezing needles. Anticipated pain was similar in room temperature, 5.1 +/- 1.7, and subfreezing groups, 4.9 +/- 2.0, respectively (p = 0.6). Actual pain was also similar in the room temperature, 3.6 +/- 2.0, and subfreezing groups, 2.8 +/- 2.0, respectively (p = 0.14). Similar numbers of subjects in the room temperature and subfreezing groups reported less actual pain (20 vs. 18), greater actual pain (4 vs. 4) or no difference in pain (9 vs. 5) than anticipated (p = 0.6).

CONCLUSION

A subfreezing 22-gauge spinal needle does not decrease perceived pain associated with second trimester genetic amniocentesis.

Psychological effects of amniocentesis on women and their spouses: importance of the testing period and genetic counseling

OBJECTIVE

To evaluate both women's and their spouses' reasons for undergoing amniocentesis, their concerns relating to the procedure as well as their psychological reactions and coping mechanisms during the testing period.

METHODS

Eighty-five women undergoing amniocentesis and their spouses took part in the study. The couples completed a questionnaire that provided demographic data and insights into their experiences of amniocentesis.

RESULTS

Age was the main reason for undergoing amniocentesis. When they first learned that they were going to undergo amniocentesis, women were more concerned about the potential danger to their fetus than their spouses. Most of participants believed that their pregnancy would continue after amniocentesis. However, they also stated that they were prepared for an abortion. Uncertainty and tension were two significant emotions experienced by couples while waiting for the test results. For the majority of women (80%) and men (42.3%) the strongest support was provided by their spouses during this period. In summary, we can conclude that the test did have a major psychological impact on both women and their spouses, but did not have a negative impact on their coping mechanisms.

CONCLUSION

The psychological impact of amniocentesis on women and their spouses does not constitute a major obstacle to their ability to cope. However, a certain number of couples reported feelings of uncertainty, tension and anxiety about fetal injury. We strongly suggest that counseling should be given to high-risk families and that prenatal/antenatal care units must be established.

Maternal anxiety at amniocentesis and plasma cortisol

OBJECTIVES

To assess whether anticipation of amniocentesis is linked with maternal anxiety, and whether this anxiety is associated with increased maternal plasma cortisol.

METHODS

Two hundred and fifty-four women awaiting a morning amniocentesis for karyotyping (gestation range 15-37 weeks, median 17 weeks) completed Spielberger state and trait anxiety inventory (STAI) questionnaires, and provided blood samples immediately before the procedure for cortisol assay. Six hundred and five women at mean gestation of 20 weeks, attending the same hospital for routine ultrasound but not for amniocentesis, also completed Spielberger STAI questionnaires and served as a comparison group for the anxiety ratings.

RESULTS

Mean state and trait anxiety scores (+/- SD) in the comparison group of 605 women at mean gestation of 20 weeks were 36.1 +/- 10.2 (range 20-70) and 35.6 +/- 8.9 (range 20-73), respectively. The mean state anxiety score (+/-SD) of 49.8 +/- 14.0 (range 20-77) of the amniocentesis group was considerably higher than the comparison group (p < 0.001), although the mean trait anxiety score in the amniocentesis group was similar at 36.4 +/- 8.6 (range 21-60). The state, but not trait, anxiety correlated with plasma cortisol (r = 0.176, p = 0.005). Maternal cortisol in the amniocentesis group increased with gestational age (r = 0.310, p < 0.001), whereas state anxiety scores showed no significant change with increase in gestational age (r = - 0.042, ns). Multivariate analysis demonstrated that maternal state anxiety was positively correlated with plasma cortisol independent of gestation and time of collection.

CONCLUSION

Women awaiting amniocentesis experience a high state anxiety associated with modestly increased plasma cortisol.

How painful are amniocentesis and chorionic villus sampling?

OBJECTIVES

To compare the levels of pain and anxiety associated with amniocentesis (AC), transabdominal chorionic villus sampling (TA-CVS), and transcervical chorionic villus sampling (TC-CVS).

METHODS

We prospectively administered a questionnaire about pain and anxiety to 124 women undergoing AC, 40 undergoing TA-CVS, and 24 undergoing TC-CVS for singleton pregnancies. The level of pain was quantified with numerical and pictorial scales and the degree of anxiety was quantified with a numerical scale (0-100 in increments of 10).

RESULTS

The mean pain score for TA-CVS, 41.4 +/- 18.1, was significantly higher than that for TC-CVS, 26.4 +/- 25.3, p = 0.008. The mean pain score for AC, 35.1 +/- 27.6, was intermediate. A higher degree of anxiety was associated with younger maternal age and nulliparity. A higher degree of anxiety was associated with a higher level of pain.

CONCLUSION

In general, each procedure is associated with a tolerable amount of pain. TA-CVS appears to be the most painful procedure while TC-CVS appears to be the least painful procedure. In certain groups of patients, the procedures may be associated with higher levels of pain and/or anxiety.

Clinical correlates of pain with amniocentesis

OBJECTIVE

The purpose of this study was to determine whether sensory or affective dimensions of pain with genetic amniocentesis are associated with identifiable clinical correlates.

STUDY DESIGN

Women completed the short-form McGill Pain Questionnaire after second-trimester genetic amniocentesis. The effect of maternal weight, parity, previous amniocentesis, previous surgery, history of menstrual cramps, maternal anxiety, presence of fibroid tumors, and depth and location of needle insertion on pain intensity was determined. The T-test, correlation matrix, Kruskal-Wallis test, and multiple logistic regression were used for analysis; a probability value of <.05 was considered significant.

RESULTS

One hundred twenty-one women were enrolled: 19.3% reported no pain, 42.9% described the pain as mild, 31.1% described the pain as discomforting, and 6.7% described the pain as distressing or horrible. Mean intensity of pain was 1.6+/-1.3 (on a scale of 0-7). Pain was most often described as sharp, cramping, fearful, and stabbing. Anxiety and pain were increased in women with an indication of abnormal serum screen as compared with women with advanced maternal age. Anxiety and a history of menstrual cramps were associated with increased affective dimensions of pain and had moderate correlation with quantified pain intensity. A history of previous amniocentesis and needle insertion in the lower one third of the uterus were associated with increased pain. Maternal weight, parity, previous surgery, fibroid tumors, and depth of needle insertion were not correlated with perceived pain. Presence or absence of an accompanying person was not associated with pain intensity.

CONCLUSION

Women report mild pain or discomfort with genetic amniocentesis. Increased pain is associated with increased maternal anxiety, a history of menstrual cramps, a previous amniocentesis, and insertion of the needle in the lower uterus.

Dysthymic reactions of women undergoing chorionic villus sampling for prenatal diagnosis of hemoglobinopathies or karyotyping

OBJECTIVES

The aim of the study was to investigate the levels of anxiety and depression, as well as liability to depression, of women undergoing chorionic villus sampling (CVS) due to the risk of giving birth to a child suffering from hemoglobinopathy, or trisomy.

METHODS

The study population consisted of 309 women who attended the Fetal Medicine Unit of Alexandra Hospital, University of Athens, Athens, Greece for a first trimester chorionic villus sampling (CVS). One hundred and fifty-nine women (group A) underwent CVS due to increased possibility of carrying an embryo with beta-thalassemia, while 150 women had the procedure because of an increased nuchal translucency measurement, or a positive first trimester biochemical screening (group B). Three hundred and nine women, matched by age and gestational age with those of the study group, who were not subjected to any diagnostic intervention formed the control group. We further investigated differences of dysthymic reactions among three subgroups of women at risk for hemoglobinopathy: (a) women undergoing their first pregnancy; (b) women who had been pregnant more than once but had not any children, and (c) women who had given birth to at least one healthy child, irrespective of previous terminations.

RESULTS

The incidence of clinically elevated levels of anxiety and depression was significantly higher in groups A and B compared to controls (p<0.001), while no significant difference was found in mean anxiety and depression, as well as the liability to depression among the three groups. Clinically elevated levels of depression were found in 10.1 and 4.7% of the women of the hemoglobinopathy and karyotyping group, respectively. Especially women who had no children, due to previous pregnancy terminations presented significantly higher incidence of elevated depression compared to women who were pregnant for the first time, or women who had given birth to at least one healthy child in their life.

CONCLUSIONS

The findings of this study highlight the necessity of training medical and nursing personnel to understand and respond to the psychological and social needs of women undergoing CVS due to increased risk for hemoglobinopathy, and especially to those who have no children and who have a history of pregnancy termination due to an affected fetus.
