Society of Family Planning Clinical Recommendation: Induction of fetal asystole before abortion Jointly developed with the Society for Maternal-Fetal Medicine☆,☆☆.

This document serves as a revision to the Society of Family Planning's 2010 guidelines, integrating literature on new techniques and research and addressing the clinical, medical, and sociolegal questions surrounding the induction of fetal asystole. Insufficient evidence exists to recommend routine induction of fetal asystole before previable medication and procedural abortion. However, at periviable gestations and after fetal viability, inducing fetal asystole before abortion prevents the infrequent but serious occurrence of unanticipated expulsion of a fetus with cardiorespiratory activity (Best Practice). Defining viability is complicated as it represents a physiological continuum impacted by gestational duration along with multiple other individual clinical factors and circumstances; therefore, the exact gestational duration to offer fetal asystole will depend on the setting and clinical circumstances. If induction of fetal asystole before abortion is available, we recommend engaging in patient-centered counseling regarding the risks and benefits of induction of fetal asystole in the setting of each unique pregnancy scenario and the patient's beliefs and priorities (Best Practice). We recommend that clinicians identify the optimal pharmacologic agent to administer for a given clinical scenario based on factors such as availability of each agent; the time frame in which fetal asystole needs to be established; and clinicians' technical ability, preferences, and practice (Best Practice). Potassium chloride, lidocaine, and digoxin are all acceptable pharmaceutical agents to induce fetal asystole before abortion. To establish asystole rapidly, we suggest the use of potassium chloride (via intracardiac or intrafunic injection) or lidocaine (via intracardiac or intrafunic injection) (GRADE 2C), although intrathoracic administration of lidocaine may be acceptable. We recommend potassium chloride not be used if intracardiac or intrafunic location cannot be achieved to avoid the risk of accidental administration to the pregnant individual and because insufficient data support its efficacy via other intrafetal locations (GRADE 1C). When using digoxin, we recommend intrafetal administration (GRADE 1C), although intraamniotic administration may be acceptable depending on a clinician's technical ability and setting. Because digoxin may take several hours to induce asystole, an alternative agent should be considered in settings where fetal asystole must be confirmed rapidly.

Contraceptive content shared on social media: an analysis of Twitter.

BACKGROUND: Information on social media may affect peoples' contraceptive decision making. We performed an exploratory analysis of contraceptive content on Twitter (recently renamed X), a popular social media platform. METHODS: We selected a random subset of 1% of publicly available, English-language tweets related to reversible, prescription contraceptive methods posted between January 2014 and December 2019. We oversampled tweets for the contraceptive patch to ensure at least 200 tweets per method. To create the codebook, we identified common themes specific to tweet content topics, tweet sources, and tweets soliciting information or providing advice. All posts were coded by two team members, and differences were adjudicated by a third reviewer. Descriptive analyses were reported with accompanying qualitative findings. RESULTS: During the study period, 457,369 tweets about reversible contraceptive methods were published, with a random sample of 4,434 tweets used for final analysis. Tweets most frequently discussed contraceptive method decision-making (26.7%) and side effects (20.5%), particularly for long-acting reversible contraceptive methods and the depot medroxyprogesterone acetate shot. Tweets about logistics of use or adherence were common for short-acting reversible contraceptives. Tweets were frequently posted by contraceptive consumers (50.6%). A small proportion of tweets explicitly requested information (6.2%) or provided advice (4.2%). CONCLUSIONS: Clinicians should be aware that individuals are exposed to information through Twitter that may affect contraceptive perceptions and decision making, particularly regarding long-acting reversible contraceptives. Social media is a valuable source for studying contraceptive beliefs missing in traditional health research and may be used by professionals to disseminate accurate contraceptive information.

Transabdominal lidocaine to induce fetal demise: a cohort study.

INTRODUCTION: We sought to assess the efficacy of transabdominal intrafetal lidocaine to achieve fetal demise before pregnancy termination. METHODS: This study was a retrospective cohort analysis of patients undergoing transabdominal intrafetal lidocaine injections prior to abortion procedures after 24 weeks from January 2018 to June 2020 at DuPont Clinic, an outpatient obstetrics and gynaecology clinic in Washington, DC, USA. We recorded data on maternal factors, gestational age, time of injection and fetal asystole, and injection dose and location. We defined successful intrafetal lidocaine injection as asystole achieved prior to the patient leaving the clinic. RESULTS: We performed injections in 338 fetuses in 335 patients, with a median gestational age of 27 weeks and 6 days (range 24-32 weeks). Lidocaine dose was 200-240 mg in 310 cases (91.7%) and 400-480 mg in 27 cases (8.0%) without difference in success (p>0.05). Lidocaine successfully induced fetal demise with one injection in 331 cases (97.9%). A second injection was required to induce demise for five fetuses (1.5%). Intracardiac injection was successful in 280 of 285 cases (98.3%), with asystole confirmed within 1 min in 75% of cases. Intrathoracic injection caused asystole in 45 of 47 cases (95.7%), with asystole confirmed within 2 min in 75% of cases. Success was not significantly associated with gestational age, body mass index or parity (p>0.05). One patient reported lidocaine-related side effects (0.3%). CONCLUSIONS: Intrafetal lidocaine is a safe and effective method of inducing fetal demise. Intracardiac injection achieves fetal asystole almost immediately. Intrathoracic injection is also highly effective.
