Pulsatile vessel at the posterior bladder wall: A new sonographic marker for placenta percreta.

OBJECTIVE: We investigated using "pulsatile vessels at the posterior bladder wall" as a novel sonographic marker to demonstrate the severity of placenta accreta spectrum (PAS). METHODS: This observational case-control study of 30 pregnant women was performed at Hackensack Meridian Health's Center for Abnormal Placentation in 2020. The case group was made up of women with historically described sonographic signs of PAS and was compared against two control groups: (1) women with uncomplicated placenta previa and (2) women with no evidence of placenta previa sonographically. All patients were evaluated with Color Flow Doppler ultrasound to assess the presence of arterial vessels at the posterior bladder wall. The flow characteristics and resistance indices (RI) were noted in the presence of pulsatile vessels. All patients' placentation was clinically confirmed at delivery. Patients with clinical invasive placentation underwent histopathological diagnosis to confirm disease presence. RESULTS: Hundred percent of subjects in our series with suspected PAS exhibited pulsatile arterial vessels at the posterior bladder wall sonographically with a low RI of 0.38 ± 0.1 at an average of 24.6 ± 5.2 gestational weeks. Cases were histopathologically confirmed to have placenta percreta after delivery. Patients in either of the control groups did not display pulsatile vessels at the posterior bladder wall during antenatal sonographic evaluations and had no clinical evidence of PAS. CONCLUSION: The presence of posterior urinary bladder wall pulsatile arterial vessels with low RI, in addition to traditional sonographic markers increases the suspicion of severe PAS. Thus, these findings allow for the greater opportunity for coordination of patient care prior to delivery.

Measuring handoff quality in labor and delivery: development, validation, and application of the Coordination of Handoff Effectiveness Questionnaire (CHEQ).

BACKGROUND: A prospective, nonblinded intervention study was conducted (1) to evaluate the psychometric properties of a new questionnaire, the CHEQ (Coordination of Handoff Effectiveness Questionnaire) for measuring the quality of handoff interactions in labor and delivery (L&D) and (2) to demonstrate the utility of the CHEQ in evaluating the effectiveness of a previously described intervention, the tangible handoff, for standardizing handoffs in L&D. METHODS: The CHEQ incorporates three existing handoff-related scales: teamwork climate, job satisfaction, and burnout. Two new scales--information quality and process quality--were developed, refined, and evaluated. The CHEQ was administered to 56 eligible L&D nurses pre- and post-implementation of the tangible handoff intervention. RESULTS: Baseline and postintervention response rates for the CHEQ were 98% and 84%, respectively. Overall, the teamwork climate scale significantly improved from 57.17% to 68.35% (t = -2.84, p = .006), and the burnout scale significantly decreased from 49.70% to 36.21% (t = -2.56, p = .012) following implementation of the tangible handoff. Job satisfaction improved, although not at a statistically significant level. Cronbach's alpha results ranged from .68 to .96 for all scales, both pre- and post-intervention. CONCLUSIONS: The CHEQ is psychometrically sound for evaluating handoffquality, is practical to administer, achieves high response rates, and is amenable to straightforward statistical analysis. The CHEQ is useful for evaluating handoff quality and gauging the responsiveness to a unit-level intervention in the scope of unit-level climate. The CHEQ may be replicated or adapted for other clinical areas to investigate handoffs and inform the design and evaluation of handoff interventions.

Measurement of intraabdominal pressure in pregnant women at term.

OBJECTIVE: To determine the baseline intraabdominal pressure (IAP) in pregnant women at term. STUDY DESIGN: Pregnant women at term undergoing scheduled cesarean delivery in the absence of labor had IAP measured via an intravesical catheter. Abdominal pressures were obtained in the dorsal supine position with a leftward tilt after the placement of spinal anesthesia. Measurements were taken immediately before and after cesarean delivery. RESULTS: One hundred subjects were included in this Institutional Research Board-approved study. The median preoperative IAP measurement was 22 mm Hg, and the median postoperative IAP measurement was 16 mm Hg. The decrease in the IAP from the preoperative to the postoperative measurement was statistically significant (p < 0.0001). CONCLUSION: The median IAP measurement for pregnant patients at term is 22 mm Hg and is followed by a statistically significant decline after delivery.

The tangible handoff: a team approach for advancing structured communication in labor and delivery.

The tangible handoff tool, a standardized, patient-specific, two-sided pocket card that guides nurses through transfer of care at each shift, is intended to improve continuity and coordination of care in labor and delivery.

Eclampsia complicated by abdominal compartment syndrome.

A primigravida with eclampsia and hemolytic anemia, elevated liver enzymes, and low platelet count (HELLP syndrome) developed intra-abdominal compartment syndrome requiring a decompressive laparotomy, underlining the importance of including abdominal compartment syndrome in the differential diagnosis in pregnant women.

Ultrasound evaluation of the uterine scar after cesarean delivery: a randomized controlled trial of one- and two-layer closure.

OBJECTIVE: To survey the uterine scar thickness by ultrasonography in women randomly assigned to one- or two-layer hysterotomy closure after primary cesarean delivery. METHODS: This was a randomized, blinded trial of uterine scar closure with ultrasonographic follow-up. Thirty consecutive patients undergoing primary cesarean delivery were enrolled and randomly assigned to one- or two-layer closure of the hysterotomy. Ultrasound surveillance of the uterine scar thickness was performed at baseline (before surgery) and 48 hours, 2 weeks, and 6 weeks post partum. RESULTS: Patient compliance with the postpartum surveillance protocol was 90%, and the uterine scar was visualized in 99% of attempted ultrasonographic examinations. There were no differences between groups at baseline or at any of the follow-up evaluations. An initial 5- to 6-fold increase in uterine scar thickness was observed, followed by a gradual decrease with the 6-week measurements still thicker than baseline. Repeated measures analysis of variance showed significant variation across time points starting either at baseline (P<.001) or at 48 hour postoperatively (P<.001), but this variation did not depend on closure type (P=.79 for all visits and P=.81 beginning with 48-hour postoperative time point). CONCLUSION: The process of uterine scar remodeling can be successfully monitored by ultrasonography. Uterine scar thickness diminishes progressively after both one- or two-layer closure but does not vary with mode of hysterotomy closure. The uterine scar thickness remains increased even at 6 weeks post partum, suggesting that the process of uterine scar remodeling extends beyond the traditional postpartum period.

Brain natriuretic peptide in term pregnancy.

OBJECTIVE: To determine the normal range of serum brain natriuretic peptide (BNP) in uncomplicated, singleton term pregnant patients. STUDY DESIGN: Serum for analysis of BNP was drawn at admission to labor and delivery (= 104), prior to administration of intravenous fluid. RESULTS: Median BNP was 20 pg/mL, with an interquartile range of 20 pg/mL (range 5-70 pg/mL; or a mean ± standard deviation [SD] of 23 ± 16 pg/mL). Brain natriuretic peptide negatively correlated with prepregnant (r = -.24, P < .05) and pregnant weight (r = -26, P < .01) and with heart rate (r = -.35, P < 0.001); heart rate was also positively correlated with BMI (r = .32). Brain natriuretic peptide levels were higher in Hispanic than African American women, independent of body mass index (BMI) and heart rate. CONCLUSIONS: Brain natriuretic peptide values found in term pregnant patients are similar to those of prepregnant women of reproductive age. Brain natriuretic peptide levels appear to be set by conditions present in the prepregnant condition and maintained, despite changes in plasma volume, systemic vascular resistance, and cardiac output.
