Waiting for the Tide to Change: Reducing Risk in the Turbulent Sea of Liability

Oxytocin augmentation and neurotransmitters in prolonged delivery: An experimental appraisal

The uterus is a highly innervated organ, and during labor, this innervation is at its highest level. Oxytocinergic fibers play an important role in labor and delivery and, in particular, the Lower Uterine Segment, cervix, and fundus are all controlled by motor neurofibers. Oxytocin is a neurohormone that acts on receptors located on the membrane of the smooth cells of the myometrium. During the stages of labor and delivery, its binding causes myofibers to contract, which enables the fundus of the uterus to act as a mediator. The aim of this study was to investigate the presence of oxytocinergic fibers in prolonged and non-prolonged dystocic delivery in a cohort of 90 patients, evaluated during the first and second stages of labor. Myometrial tissue samples were collected and evaluated by electron microscopy, in order to quantify differences in neurofibers concentrations between the investigated and control cohorts of patients. The authors of this experiment showed that the concentration of oxytocinergic fibers differs between non-prolonged and prolonged dystocic delivery. In particular, in prolonged dystocic delivery, compared to non-prolonged dystocic delivery, there is a lower amount of oxytocin fiber. The increase in oxytocin appeared to be ineffective in patients who experienced prolonged dystocic delivery, since the dystocic labor ended as a result of the altered presence of oxytocinergic fibers detected in this group of patients.

Liability, risks, and recommendations for ultrasound use in the diagnosis of obstetrics diseases

This literature review will summarize the liability issues, risks, and ultrasound recommendations for diagnosing obstetrics diseases. One liability issue is related to misdiagnosis or failure to detect abnormalities during an ultrasound examination. Ultrasound images can be subjective interpretations, and errors may occur due to factors such as operator skill, equipment limitations, or fetal positioning. Another liability concern is related to the potential adverse effects of ultrasound exposure on both the mother and fetus. While extensive research has shown that diagnostic ultrasound is generally safe when used appropriately, there are still uncertainties regarding long-term effects. Some studies suggest a possible association between prolonged or excessive exposure to ultrasound waves and adverse outcomes such as low birth weight, developmental delays, or hearing impairment. Additionally, obtaining informed consent from patients is crucial in mitigating liability risks. Patients should be informed about the purpose of the ultrasound examination, its benefits, limitations, potential risks (even if minimal), and any alternative diagnostic options available. This ensures that patients know the procedure and can make informed decisions about their healthcare. Proper documentation helps establish a clear record of the care provided and can serve as evidence in any legal disputes.

The association between abortion restrictions and patient-centered care for early pregnancy loss at US obstetrics-gynecology residency programs

BACKGROUND

Early pregnancy loss is a common medical problem, and the recommended treatments overlap with those used for induced abortions. The American College of Obstetricians and Gynecologists recommends the incorporation of clinical and patient factors when applying conservative published imaging guidelines to determine the timing of intervention for early pregnancy loss. However, in places where abortion is heavily regulated, clinicians who manage early pregnancy loss may cautiously rely on the strictest criteria to differentiate between early pregnancy loss and a potentially viable pregnancy. The American College of Obstetricians and Gynecologists also notes that specific treatment modalities that are frequently used to induce abortion, including the use of mifepristone in medical therapy and surgical aspiration in an office setting, are cost-effective and beneficial for patients with early pregnancy loss.

OBJECTIVE

This study aimed to determine how US-based obstetrics and gynecology residency training institutions adhere to the American College of Obstetricians and Gynecologists recommendations for early pregnancy loss management, including the timing and types of interventions, and to evaluate the relationship with institutional and state abortion restrictions.

STUDY DESIGN

From November 2021 to January 2022, we conducted a cross-sectional study of all 296 US-based obstetrics and gynecology residency programs by emailing them and requesting that a faculty member complete a survey about early pregnancy loss practices at their institution. We asked about location of diagnosis, use of imaging guidelines before offering intervention, treatment options available at their institution, and program and personal characteristics. We used chi-square tests and logistic regressions to compare the availability of early pregnancy loss care based on institutional indication-based abortion restrictions and state legislative hostility to abortion care.

RESULTS

Of the 149 programs that responded (50.3% response rate), 74 (49.7%) reported that they did not offer any intervention for suspected early pregnancy loss unless rigid imaging criteria were met, whereas the remaining 75 (50.3%) programs reported that they incorporated imaging guidelines with other factors. In an unadjusted analysis, programs were less likely to incorporate other factors with imaging criteria if they were in a state with legislative policies that were hostile toward abortion (33% vs 79%; P<.001) or if the institution restricted abortion by indication (27% vs 88%; P<.001). Mifepristone was used less often in programs located in hostile states (32% vs 75%; P<.001) or in institutions with abortion restrictions (25% vs 86%; P<.001). Similarly, office-based suction aspiration use was lower in hostile states (48% vs 68%; P=.014) and in institutions with restrictions (40% vs 81%; P<.001). After controlling for program characteristics, including state policies and affiliation with family planning training programs or religious entities, institutional abortion restrictions were the only significant predictor of rigid reliance on imaging guidelines (odds ratio, 12.3; 95% confidence interval, 3.2-47.9).

CONCLUSION

In training institutions that restrict access to induced abortion based on indication for care, residency programs are less likely to holistically incorporate clinical evidence and patient priorities in determining when to intervene in early pregnancy loss as recommended by the American College of Obstetricians and Gynecologists. Programs in restrictive institutional and state environments are also less likely to offer the full range of early pregnancy loss treatment options. With state abortion bans proliferating nationwide, evidence-based education and patient-centered care for early pregnancy loss may also be hindered.

"Pseudogestational Sac" and Other 1980s-Era Concepts in Early First-Trimester Ultrasound: Are They Still Relevant Today?

OBJECTIVES

To determine whether an intrauterine round or oval fluid collection ("saclike structure") can prove to be either an intrauterine pregnancy or intrauterine fluid in conjunction with an ectopic pregnancy (sometimes termed "pseudogestational sac") and whether ultrasound features, including the presence or absence of an echogenic rim, "double sac sign" (DSS), or "intradecidual sign" (IDS), are helpful for establishing the diagnosis or predicting the prognosis.

METHODS

We identified all sonograms obtained from women with positive serum human chorionic gonadotropin results at our institution between January 1, 2012, and June 30, 2018, meeting the following criteria: presence of an intrauterine saclike structure without a yolk sac or embryo; no extraovarian adnexal mass; and follow-up information identifying the location of the pregnancy as intrauterine or ectopic. Study authors reviewed sonograms in all cases and recorded the following information: presence or absence of each of an echogenic rim around the collection, a DSS, and an IDS, as well as the mean sac diameter. The indications for the initial ultrasound examinations were recorded.

RESULTS

A total of 649 sonograms met the inclusion criteria. Of these, 598 fluid collections showed an echogenic rim, 182 a DSS, and 347 an IDS (findings not mutually exclusive). In all 649 cases, a subsequent sonogram or other clinical follow-up confirmed that the patient had an intrauterine pregnancy. That is, none of the fluid collections proved to be a pseudogestational sac. In total, 41.2% were live at the end of the first trimester, and 58.8% miscarried. The prognosis was better in cases with, compared to without, an IDS (P = .01, χ² ), but no ultrasound feature was clinically useful for ruling in or excluding a good prognosis.

CONCLUSIONS

In a woman with positive human chorionic gonadotropin results and no extraovarian adnexal mass, the ultrasound finding of an intrauterine saclike structure is virtually certain to be a gestational sac. Ultrasound features of the structure are of no diagnostic or clinically useful prognostic value. Concepts introduced 30 to 40 years ago when ultrasound equipment had far lower resolution than currently, including a DDS, an IDS, and a pseudogestational sac, have no role today in assessing early pregnancy.

A survey of central association members about the definition, management, and complications of shoulder dystocia

OBJECTIVES

To determine practice patterns for shoulder dystocia and concepts dealing with brachial plexus palsy.

METHODS

An Internet-based 25-question survey was electronically disseminated to all current members of the Central Association of Obstetricians and Gynecologists. For those individuals who did not respond, an additional opportunity to complete the assessment was provided during the 2009 annual meeting.

RESULTS

Of 429 Central Association of Obstetricians and Gynecologists members, 268 (62%) responded, with 192 (78%) filling out the survey online. Nearly 90% of those queried believed that shoulder dystocia was unpredictable and unpreventable. Thirty-seven percent felt that an elective cesarean delivery should be offered for an estimated fetal weight of 4,500 g among nondiabetics. Just 40% would have allowed a trial of labor with a documented history of shoulder dystocia. Slightly more than half answered that they never used either lateral or excessive traction and obstetrician-gynecologists were more likely than maternal-fetal medicine specialists to conclude that traction applied by the clinician doing the delivery was the cause of shoulder dystocia-related brachial plexus palsy (36% compared with 12%, P=.005). Maternal-fetal medicine specialists were more likely to believe that 40-50% of brachial plexus palsies occur without concomitant shoulder dystocia (21% compared with 9%, P=.015).

CONCLUSION

Differences in practice patterns exist among with regard to management recommendations of the American College of Obstetricians and Gynecologists' Practice Bulletin on shoulder dystocia.
