Society of Family Planning clinical recommendations: Cervical preparation for dilation and evacuation at 20-24 weeks' gestation

Trends in Invasive Prenatal Testing, Diagnosis, and Abortion for Fetal Aneuploidy

We aimed to assess trends in prenatal testing for aneuploidy, including indications, diagnostic yield, and the timing of diagnosis and abortions since the introduction of cell-free DNA (cfDNA) into routine prenatal care.In this observational retrospective study, all invasive prenatal diagnostic procedures performed at a single institution from 2010 to 2022 were evaluated. Clinical variables included gestational age (GA) at testing, indications, results, and pregnancy outcomes (continuation or abortion). Description statistics were used to characterize the sample.A total of 1,262 diagnostic procedures were performed during the study period, with 20.5% (n = 258) confirming genetic abnormalities. Amniocentesis accounted for 70.4% (n = 888) of diagnostic procedures, while 29.6% underwent chorionic villus sampling (CVS; n = 374). The number of procedures decreased significantly over time (p < 0.001). Indications for testing shifted dramatically; testing for the indication of advanced maternal age alone fell from 45 to 5.6% (p < 0.001). Patients with abnormal cfDNA screening results underwent diagnostic testing at an earlier average gestational age (15.3 vs. 17.8 weeks; p < 0.001), had a higher likelihood of undergoing CVS (30.7 vs. 8.9%; p < 0.001), and had higher rates of abnormal cytogenetics (60.4 vs. 13.2%; p < 0.001) compared to patients with analyte testing. Patients diagnosed with aneuploidy following abnormal cfDNA underwent abortion at earlier GA (15.5 vs.19.3 weeks; p = 0.002).cfDNA screening has reduced prenatal invasive diagnostic procedures and shifted testing indications. Abnormal cfDNA screening is associated with a higher diagnostic yield and earlier GA at diagnosis and abortion after confirmation of aneuploidy. Despite these advances, aneuploidy diagnosis continues to extend into the second trimester, highlighting ongoing challenges in early detection. · The introduction of cfDNA has reduced rates of invasive diagnostic procedures, shifting the most frequent indications for testing from advanced maternal age to abnormal ultrasound findings.. · Despite the use of cfDNA screening at earlier gestational ages compared with traditional analyte testing, the gestational age at which diagnostic procedures and abortions are performed for fetal aneuploidy has remained in the second trimester.. · Although cfDNA testing leads to earlier and more frequent identification of aneuploidy, confirmation of abnormal results often occurs after gestational age thresholds for abortion in many states..

Obstetric anesthesia management of dilated cardiomyopathies and heart failure: a narrative review

Pregnancy in patients with dilated cardiomyopathy carries a significantly increased risk of maternal mortality or severe morbidity, and pregnancy is typically considered contraindicated for patients with severely reduced ventricular function. Nonetheless, anesthesiologists will still encounter patients with cardiomyopathy requiring delivery or termination care. This review describes how NT-ProBNP testing and echocardiography can help with early recognition of heart failure in pregnancy, and describes a suggested approach to anesthetic management of patients with cardiomyopathies or acute heart failure, including hemodynamic goals, use of vasoactive medications and mechanical support. Vaginal delivery, with effective neuraxial anesthesia is the preferred mode of delivery in most patients with cardiomyopathy, with cesarean delivery reserved for maternal or fetal indications. The Pregnancy Heart Team is vital in coordinating the multidisciplinary care necessary to safely support these patients through pregnancy.

Society for Maternal-Fetal Medicine Consult Series #71: Management of previable and periviable preterm prelabor rupture of membranes

Previable and periviable preterm prelabor rupture of membranes are challenging obstetrical complications to manage given the substantial risk of maternal morbidity and mortality, with no guarantee of fetal benefit. The following are the Society for Maternal-Fetal Medicine recommendations for the management of previable and periviable preterm prelabor rupture of membranes before the period when a trial of neonatal resuscitation and intensive care would be considered appropriate by the healthcare team and desired by the patient: (1) we recommend that pregnant patients with previable and periviable preterm prelabor rupture of membranes receive individualized counseling about the maternal and fetal risks and benefits of both abortion care and expectant management to guide an informed decision; all patients with previable and periviable preterm prelabor rupture of membranes should be offered abortion care, and expectant management can also be offered in the absence of contraindications (GRADE 1C); (2) we recommend antibiotics for pregnant individuals who choose expectant management after preterm prelabor rupture of membranes at ≥24 0/7 weeks of gestation (GRADE 1B); (3) antibiotics can be considered after preterm prelabor rupture of membranes at 20 0/7 to 23 6/7 weeks of gestation (GRADE 2C); (4) administration of antenatal corticosteroids and magnesium sulfate is not recommended until the time when a trial of neonatal resuscitation and intensive care would be considered appropriate by the healthcare team and desired by the patient (GRADE 1B); (5) serial amnioinfusions and amniopatch are considered investigational and should be used only in a clinical trial setting; they are not recommended for routine care of previable and periviable preterm prelabor rupture of membranes (GRADE 1B); (6) cerclage management after previable or periviable preterm prelabor rupture of membranes is similar to cerclage management after preterm prelabor rupture of membranes at later gestational ages; it is reasonable to either remove the cerclage or leave it in situ after discussing the risks and benefits and incorporating shared decision-making (GRADE 2C); and (7) in subsequent pregnancies after a history of previable or periviable preterm prelabor rupture of membranes, we recommend following guidelines for management of pregnant persons with a previous spontaneous preterm birth (GRADE 1C).

Abortion

Induced abortion is safe, is common, and reduces pregnancy-related maternal morbidity and mortality. Internal medicine physicians are uniquely positioned to counsel patients on their pregnancy options, assess medical risks of pregnancy in the context of comorbidities, refer for abortion care when the patient desires it, or provide abortion care themselves. Clinicians can also provide anticipatory guidance about what patients should expect if they seek abortion care.

The hormonal control of parturition

Parturition is a complex physiological process that must occur in a reliable manner and at an appropriate gestation stage to ensure a healthy newborn and mother. To this end, hormones that affect the function of the gravid uterus, especially progesterone (P4), 17β-estradiol (E2), oxytocin (OT), and prostaglandins (PGs), play pivotal roles. P4 via the nuclear P4 receptor (PR) promotes uterine quiescence and for most of pregnancy exerts a dominant block to labor. Loss of the P4 block to parturition in association with a gain in prolabor actions of E2 are key transitions in the hormonal cascade leading to parturition. P4 withdrawal can occur through various mechanisms depending on species and physiological context. Parturition in most species involves inflammation within the uterine tissues and especially at the maternal-fetal interface. Local PGs and other inflammatory mediators may initiate parturition by inducing P4 withdrawal. Withdrawal of the P4 block is coordinated with increased E2 actions to enhance uterotonic signals mediated by OT and PGs to promote uterine contractions, cervix softening, and membrane rupture, i.e., labor. This review examines recent advances in research to understand the hormonal control of parturition, with focus on the roles of P4, E2, PGs, OT, inflammatory cytokines, and placental peptide hormones together with evolutionary biology of and implications for clinical management of human parturition.

Adjuvant misoprostol or mifepristone for cervical preparation with osmotic dilators before dilation and evacuation

OBJECTIVES

This study aimed to compare effectiveness and safety of cervical preparation with osmotic dilators plus same-day misoprostol or overnight mifepristone prior to dilation and evacuation (D&E).

STUDY DESIGN

We conducted a retrospective cohort analysis of 664 patients initiating abortion between 18 and 22 weeks at an ambulatory health center. We abstracted medical record data from two consecutive 12-month periods in 2017 to 2019. All patients received overnight dilators plus: 600 mcg buccal misoprostol 90 minutes before D&E (period 1); 200 mg oral mifepristone at time of dilators (period 2). Our primary outcome was procedure time. We report frequency of patients experiencing any acute complication, defined as unplanned procedure (i.e., reaspiration, cervical laceration repair, uterine balloon tamponade) or hospital transfer and bleeding complications.

RESULTS

We observed higher mean procedure time in the mifepristone group (9.7 ± 5.3 minutes vs 7.9 ± 4.4, p = 0.004). After adjusting for race, ethnicity, insurance, body mass index, parity, prior cesarean, prior uterine surgery, gestational age, provider, trainee participation, and long-acting reversible contraception initiation, the difference remained statistically significant (relative change 1.09, 95% CI 1.01, 1.17) but failed to reach our threshold for clinical significance. The use of additional misoprostol was more common in the mifepristone group, but the use of an additional set of dilators was not different between groups. Acute complications occurred at a frequency of 4.1% in misoprostol group and 4.3% in mifepristone group (p = 0.90).

CONCLUSIONS

We found procedure time to be longer with adjunctive mifepristone compared to misoprostol; however, this difference is unlikely to be clinically meaningful. Furthermore, the frequency of acute complications was similar between groups.

IMPLICATIONS

Overnight mifepristone at the time of cervical dilator placement is a safe and effective alternative to adjuvant same-day misoprostol for cervical preparation prior to D&E and may offer benefits for clinic flow and patient experience.

Society of Family Planning Clinical Recommendation: Management of hemorrhage at the time of abortion

Hemorrhage after abortion is rare, occurring in fewer than 1% of abortions, but associated morbidity may be significant. Although medication abortion is associated with more bleeding than procedural abortion, overall bleeding for the two methods is minimal and not clinically different. Hemorrhage can be caused by atony, coagulopathy, and abnormal placentation, as well as by such procedure complications as perforation, cervical laceration, and retained tissue. Evidence for practices around postabortion hemorrhage is extremely limited. The Society of Family Planning recommends preoperative identification of individuals at high risk of hemorrhage as well as development of an organized approach to treatment. Specifically, individuals with a uterine scar and complete placenta previa seeking abortion at gestations after the first trimester should be evaluated for placenta accreta spectrum. For those at high risk of hemorrhage, referral to a higher-acuity center should be considered. We propose an algorithm for treating postabortion hemorrhage as follows: (1) assessment and examination, (2) uterine massage and medical therapy, (3) resuscitative measures with laboratory evaluation and possible reaspiration or balloon tamponade, and (4) interventions such as embolization and surgery. Evidence supports the use of oxytocin as prophylaxis for bleeding with dilation and evacuation; methylergonovine prophylaxis, however, is associated with more bleeding at the time of dilation and evacuation. Future research is needed on tranexamic acid as prophylaxis and treatment and misoprostol as prophylaxis. Structural inequities contribute to bleeding risk. Acknowledging how our policies hinder or remedy health inequities is essential when developing new guidelines and approaches to clinical services.

Cervical preparation for second-trimester procedural abortion

PURPOSE OF REVIEW

To review the evidence-informed options for cervical preparation prior to second-trimester dilation and evacuation (D&E).

RECENT FINDINGS

As abortion restrictions increase and the number of abortion clinics and providers decreases, pregnant people are facing more barriers to abortion access. Those in need are now often required to travel for second-trimester abortion care, only to be faced with additional restrictions, such as mandatory waiting periods. Cervical preparation is recommended prior to D&E and takes time for effect. Given the increasing time required to obtain an abortion, patients and providers may prefer same-day cervical preparation to decrease the total time required. Options for same-day cervical preparation include misoprostol alone with single or serial doses, and misoprostol combined with osmotic dilators or transcervical balloon (Foley catheter). Same-day preparation may require additional clinical space to accommodate people after initiation of cervical preparation to manage side-effects and timing of the abortion. Overnight options are also used and more frequently later in the second trimester. Overnight options include mifepristone, osmotic dilators, and transcervical balloon and are often combined with same-day misoprostol. Medication alone preparation is well tolerated and effective in the second trimester, with the addition of mechanical methods with advancing gestation. With many options and combinations being safe and effective, providers can be dynamic and alter approach with supply shortages, adjust to different clinical settings, consider patient medical and surgical factors, and accommodate provider and patient preferences.

SUMMARY

Multiple pharmacologic and mechanical options have been shown to be safe and effective for cervical preparation prior to D&E. Consideration for multiple factors should influence the method of cervical preparation and methods may vary by patient, provider and setting.

Medication Abortion: A Comprehensive Review

This chapter provides an overview of evidence-based guidelines for medication abortion in the first trimester. We discuss regimens, both FDA-approved and other clinical-based protocols, and will briefly discuss novel self-managed abortion techniques taking place outside the formal health care system. Overview of patient counseling and pain management are presented with care to include guidance on "no touch" regimens that have proven both feasible and effective. We hope that this comprehensive review helps the health care community make strides to increase access to abortion in a time when reproductive health care is continuously restricted.

First and Second-Trimester Surgical Abortion Providers and Services in 2019: Results From the Canadian Abortion Provider Survey

OBJECTIVE

Our objective was to explore the workforce and clinical care of first and second-trimester surgical abortion (FTSA, STSA) providers following the publication of the updated Society of Obstetricians and Gynaecologists of Canada (SOGC) surgical abortion guidelines.

METHODS

We conducted a national, cross-sectional, online, self-administered survey of physicians who provided abortion care in 2019. This anonymized survey collected participant demographics, types of abortion services, and characteristics of FTSA and STSA clinical care. Through healthcare organizations using a modified Dillman technique, we recruited from July to December 2020. Descriptive statistics were generated by R Statistical Software.

RESULTS

We present the data of 222 surgical abortion provider respondents, of whom 219 provided FTSA, 109 STSA, and 106 both. Respondents practiced in every Canadian province and territory. Most were obstetrician-gynaecologists (56.8%) and family physicians (36.0%). The majority of FTSA and STSA respondents were located in urban settings, 64.8% and 79.8%, respectively, and more than 80% practiced in hospitals. More than 1 in 4 respondents reported <5 years' experience with surgical abortion care and 93.2% followed SOGC guidelines. Noted guideline deviations included that prophylactic antibiotic use was not universal, and more than half of respondents used sharp curettage in addition to suction. Fewer than 5% of STSA respondents used mifepristone for cervical preparation.

CONCLUSION

The surgical abortion workforce is multidisciplinary and rejuvenating. Education, training, and practice support, including SOGC guideline implementation, are required to optimize care and to ensure equitable FTSA and STSA access in both rural and urban regions. GESTATIONAL AGE NOTATION: weeks, weeks' gestation, gestational age (GA), e.g., 116 weeks.

Second-trimester Abortion

In 2019, the US Centers for Disease Control reported that 7% of abortions were performed after 13 weeks of pregnancy, a small proportion of all terminations. However, the need for second-trimester abortions will increase commensurate with restrictions to access nationwide. Second-trimester abortions are performed with medications or through a procedure. Health care practitioners serving persons at risk of pregnancy should understand how abortions are performed and how to deliver evidence-based postabortion care. The purpose of this article is to provide a foundation for caring for individuals before, during, and after second-trimester abortion.

Anesthetic Considerations for Second-Trimester Surgical Abortions

Although most abortion care takes place in the office setting, anesthesiologists are often asked to provide anesthesia for the 1% of abortions that take place later, in the second trimester. Changes in federal and state regulations surrounding abortion services may result in an increase in second-trimester abortions due to barriers to accessing care. The need for interstate travel will reduce access and delay care for everyone, given limited appointment capacity in states that continue to support bodily autonomy. Therefore, anesthesiologists may be increasingly involved in care for these patients. There are multiple, unique anesthetic considerations to provide safe and compassionate care to patients undergoing second-trimester abortion. First, a multiday cervical preparation involving cervical osmotic dilators and pharmacologic agents results in a time-sensitive, nonelective procedure, which should not be delayed or canceled due to risk of fetal expulsion in the preoperative area. In addition, a growing body of literature suggests that the older anesthesia dogma that all pregnant patients require rapid-sequence induction and an endotracheal tube can be abandoned, and that deep sedation without intubation is safe and often preferable for this patient population through 24 weeks of gestation. Finally, concomitant substance use disorders, preoperative pain from cervical preparation, and intraoperative management of uterine atony in a uterus that does not yet have mature oxytocin receptors require additional consideration.

Second-trimester abortion care for those with complex medical conditions

PURPOSE OF THE REVIEW

This review focuses on patients who are most likely to experience morbidity associated with second trimester abortion care and risk mitigation strategies.

RECENT FINDINGS

Prior cesarean birth, particularly multiple prior cesarean births, is the most significant risk factor associated with complications during second trimester abortion because of increased risks of hemorrhage, with or without placenta accreta spectrum (PAS), and distorted anatomy, which increases the risk of uterine perforation. Recent data suggests that first trimester ultrasound findings may be predictive of PAS, including multiple lacunae, abnormal uteroplacental interface, and hypervascularity. Multiple common medications interact with mifepristone and are therefore contraindicated; ulipristal shares mifepristone's selective progesterone receptor modulator activity but does not share the same metabolic pathway. Recent data suggests ulipristal may be an effective adjunct for cervical preparation, avoiding potentially mifepristone's drug-drug interactions. Those ending a pregnancy due to severe early-onset hypertensive disorders have a high rate of clinically significant thrombocytopenia: platelet transfusion is recommended for those with platelets <50 000 per cubic millimeter.

SUMMARY

Pregnant people presenting for care in the second trimester may have conditions that make an abortion more technically or medically complex. Clinicians can mitigate much of this increased risk with preprocedural planning, and appropriate intra-operative preparedness.

Pain, Side Effects, and Abortion Experience Among People Seeking Abortion Care in the Second Trimester

Background:

There is limited documentation about pain and side effects associated with dilation and evacuation (D&E) abortion, yet, pain and side effects are important factors that can affect a client's abortion experience. In 2016, Hope Clinic for Women, an independent abortion clinic in Illinois, altered its cervical preparation protocols before D&E to reduce the total time of the abortion process and improve the client experience. This analysis addresses the gap in data on client experience of abortion in the later second trimester by evaluating pain, side effects, and acceptability by gestational age.

Methods:

Abortion clients obtaining services at the clinic between March 2017 and June 2018 were eligible to participate if they had viable singleton pregnancies of 16–23.6 weeks' gestation, spoke English, and were at least 18 years old. Eligible participants completed a two-part survey about their abortion experience.

Results:

We found that respondents seeking abortion care at later gestations in the second trimester were more likely to report pain during their abortions. We did not find any association between side effects and gestational age.

Conclusion:

Although most respondents were prepared for the pain they experienced, some reported experiencing more pain than they expected, and more effective pain relief was commonly reported as a way to improve the service. More research on patient experiences of later abortion is needed, particularly on experiences of pain and options for pain management.

Dilation and evacuation with an abdominal cerclage at 21 weeks gestation: A case report

This case demonstrates a successful dilation and evacuation (D&E) at 21 weeks gestation for a patient with abdominal cerclage without initial advanced dilation. We followed a 2-day protocol with placement of 5 laminaria and mifepristone for cervical preparation without complication.

Pain management in outpatient surgical abortion

PURPOSE OF REVIEW

To review the current literature focusing on pain management and experiences during abortion care.

RECENT FINDINGS

Analgesic options in abortion care address pain associated with the procedure, osmotic dilator insertion, and cervical preparation. The paracervical block (PCB) is effective for pain control in first and second trimester abortions. Lower volume PCBs demonstrate non inferiority with osmotic dilator placement compared with higher volume PCBs with lower potential for toxicity. Self-administered vaginal lidocaine gel is noninferior to PCB in first trimester abortions. Preoperative oral narcotics and sedation do not reduce pain in first trimester abortions; however, the latter may reduce anxiety. For second trimester abortions, narcotics or gabapentin do not improve postoperative pain, yet up to half of patients will use narcotics if offered. Nonpharmacological methods have shown success in pain management. Music and doula support do not improve pain; however, patients would recommend these modalities, indicating some benefit that went unmeasured. Auricular acupuncture and transcutaneous electrical nerve stimulation (TENS) reduce pain and anxiety during first trimester abortions.

SUMMARY

Several modalities reduce pain during abortion care; however, pain alone does not reflect patient satisfaction. Development of multidimensional measures for pain control assessment has the potential to capture the patient's overall experience.

Abortion Care Beyond 13 Weeks' Gestation: A Global Perspective

The majority of abortions are performed early in pregnancy, but later abortion accounts for a large proportion of abortion-related morbidity and mortality. People who need this care are often the most vulnerable-the poor, the young, those who experience violence, and those with significant health issues. In settings with access to safe care, studies demonstrate significant declines in abortion-related morbidity and mortality. This review focuses on evidence-based practices for induced abortion beyond 13 weeks' gestation and post-abortion care in both high- and low-resource settings. We also highlight key programmatic issues to consider when expanding the gestational age for abortion services.

Mifepristone prior to osmotic dilators for dilation and evacuation cervical preparation: A randomized, double-blind, placebo-controlled pilot study

OBJECTIVES

To evaluate mifepristone impact on osmotic dilator placement and procedural outcomes when given 18 to 24 hours before dilator placement for dilation and evacuation (D&E) at 18 weeks 0 days to 23 weeks 6 days gestation.

STUDY DESIGN

We performed a randomized, double-blind, placebo-controlled trial from April 2019 through February 2021, enrolling participants undergoing osmotic dilator (Dilapan) placement for a planned, next-day D&E. Participants took mifepristone 200 mg or placebo orally 18 to 24 hours before dilator placement. We used a gestational age-based protocol for minimum number of dilators. Our primary outcome was the proportion of participants for whom 2 or more additional dilators could be placed compared to the minimum gestational age-based standard. We secondarily evaluated cervical dilation after dilator removal in the operating room, subjective procedure ease, and complication rates (cervical laceration, uterine perforation, blood transfusion, infection, hospitalization, or extramural delivery).

RESULTS

Of the planned 66 participants, we enrolled 44 (stopped due to coronavirus disease 2019-related obstacles), and 41 (19 mifepristone; 22 placebo) completed the study. We placed 2 or more additional dilators compared to standard in 7 (36.8%) and 3 (13.6%) participants after mifepristone and placebo, respectively (p = 0.14). We measured greater median initial cervical dilation in the mifepristone (3.2 cm[2.6-3.6]) compared to placebo (2.6 cm[2.2-3.0]) group, p = 0.03. Surgeon's perception of procedure being "easy" (8/19[42.1] vs 9/22[40.9], respectively, p = 1.00) and complication rate (3/19[15.8%] vs 3/22[13.6], respectively, p = 1.00) did not differ.

CONCLUSION

Our underpowered study did not demonstrate a difference in cervical dilator placement, but mifepristone 18 to 24 hours prior to dilators increases cervical dilation without increasing complications.

IMPLICATIONS

Mifepristone 18 to 24 hours prior to cervical dilator placement may be a useful adjunct to cervical dilators based on increased cervical dilation at time of procedure; however, logistical barriers, such as an additional visit, may preclude routine adoption without definite clinical benefit.

Induction of Labour. Guideline of the DGGG, OEGGG and SGGG (S2k, AWMF Registry No. 015-088, December 2020)

Aim The aim of this official guideline published and coordinated by the German Society of Gynaecology and Obstetrics (DGGG) in cooperation with the Austrian Society of Gynaecology and Obstetrics (OEGGG) and the Swiss Society of Gynaecology and Obstetrics (SGGG) is to provide a consensus-based overview of the indications, methods and general management of induction of labour by evaluating the relevant literature. Methods This S2k guideline was developed using a structured consensus process which included representative members from various professions; the guideline was commissioned by the guidelines commission of the DGGG, OEGGG and SGGG. Recommendations The guideline provides recommendations on the indications, management, methods, monitoring and special situations occurring in the context of inducing labour.

Mechanical dilation to remove incarcerated laminaria during a second trimester abortion

Cervical preparation with laminaria reduces complications with 2nd trimester dilation and evacuation. During a surgical abortion at 22 weeks, we could not remove laminaria manually or with ring forceps due to laminaria "dumbbelling" [1]. Without pushing laminaria into the uterus, we mechanically dilated the cervix and removed the incarcerated laminaria.

A single-blinded randomized controlled trial evaluating pain and opioid use after dilator placement for second-trimester abortion

OBJECTIVES

To compare pain levels and medication needs after placement of laminaria vs Dilapan-S, and after dilation and evacuation (D&E).

STUDY DESIGN

We conducted a single-blinded randomized control trial of patients undergoing D&E at 15 0/7 to 23 6/7 weeks gestation, randomizing to cervical preparation with laminaria or Dilapan-S. We compared pain levels and medication usage following dilator placement (5 minutes; 2, 4, and 8 hours; the following morning) and D&E (1, 4, 24, and 48 hours). Our primary outcome was median change from baseline pain, and secondary outcomes included maximum pain timing and overall narcotic use. We compared baseline characteristics, median pain increases and quantities of narcotics used.

RESULTS

We analyzed 67 participants with laminaria (n = 34) and Dilapan-S (n = 33). More Dilapan-S users had a prior vaginal delivery (n = 20, 60.6%) than laminaria users (n = 11, 32.4%), p = 0.02. Maximum median pain was not statistically different (Laminaria: +3.5 (interquartile range [IQR] +0.5, +6.5); Dilapan-S: +3 (IQR +1, +5); p = 0.42. Thirty-seven (63.8%) participants reported higher levels of pain following dilator placement than D&E. Overall, 26 (42.6%) participants used narcotics during their abortion episode, with no difference in median number of tablets between laminaria (2, range 1-8) and Dilapan-S (4.5, range 1-15) participants (p = 0.34).

CONCLUSIONS

Median pain increase did not differ in participants receiving laminaria or Dilapan-S for cervical preparation prior to D&E. The majority of patients will use a small amount of narcotics if available.

IMPLICATIONS

The lack of difference in pain between laminaria and Dilapan-S enhances the applicability of pain intervention research across dilator types. With over half of participants using a small amount of narcotics during their D&E episode, pain management should be individualized to patient needs.
