Technique and diagnostic utility of saline infusion sonohysterography

The introduction of saline infusion sonohysterography has significantly improved sonographic diagnosis of various endometrial pathologies. This procedure entails instillation of warm saline into the uterine cavity transcervically to provide enhanced visualization of the endometrium during transvaginal ultrasound examination. This article reviews the sonohysterography technique and current utility, as well as the spectrum of imaging features of various endometrial pathologies.     

Comparison of saline infusion sonohysterography and hysteroscopy in diagnosis of premenopausal women with abnormal uterine bleeding

Objective

The aim of this study was to compare the diagnostic effectiveness of transvaginal sonography (TVS), saline infusion sonohysterography (SIS), and diagnostic hysteroscopy (HS), with the pathologic specimen as a gold standard diagnostic method, in detecting endometrial pathology in premenopausal women with abnormal uterine bleeding.

Study design

This prospective cohort study was conducted at Zeynep Kamil Education and Training Hospital, Istanbul, Turkey, and included 89 premenopausal women. All participants were examined first by TVS, further investigated with SIS and HS, and finally dilatation and curettage was performed when needed. The results obtained from these three methods were compared with the pathologic diagnoses. The positive and negative likelihood ratios (LR+ and LR−) of TVS, SIS and HS were calculated by comparison with the final pathological diagnosis. In addition, area under the curve (AUC) values were also calculated.

Results

Polypoid lesion was the most common abnormal pathology. LR+ and LR− of TVS, SIS, and HS were 3.13 and 0.15, 9.83 and 0.07, 13.7 and 0.02 respectively in detection of any abnormal pathology, and the AUCs of TVS, SIS, and HS were 0.804, 0.920, and 0.954 respectively. When the three procedures were compared with each other separately, HS had the best diagnostic accuracy, and the diagnostic accuracy of HS and SIS was superior to TVS (p₁ = 0.000, p₂ = 0.000). For the detection of polypoid lesions, HS was the most accurate diagnostic procedure (AUC = 0.947), followed by SIS (AUC = 0.894) and TVS (AUC = 0.778).

Conclusion

HS provides the most accurate diagnosis and allows treatment in the same session in premenopausal women with abnormal uterine bleeding.     

Intrauterine lidocaine infusion for pain relief during saline solution infusion sonohysterography: a randomized, controlled trial

STUDY OBJECTIVE: To evaluate the efficacy of intrauterine lidocaine instillation in reducing patient discomfort during saline solution infusion sonohysterography (SIS). DESIGN: A double-blinded, randomized, controlled trial (Canadian Task Force classification I). SETTING: Suleyman Demirel University School of Medicine, Department of Obstetrics and Gynecology, Isparta. PATIENTS: One hundred-six women who underwent SIS. INTERVENTIONS: Fifty-three patients were allocated to the lidocaine group and 53 to the saline solution group. MEASUREMENTS AND MAIN RESULTS: The main outcome measures were the intensity of pain during, immediately after, and 20 minutes after the procedure, assessed by a visual analog scale and the patients' distress evaluated by the physician with a 3-point observer scale. There were no statistically significant differences between the study group and the control group in mean age, parity, past cervical surgery, history of chronic pelvic pain and dysmenorrhea, history of curettage, education, socioeconomic status, menopausal status, volume of saline solution infused (mL), tenaculum use, and indication for SIS. Pain scores demonstrated a statistically significant difference between groups during the procedure (placebo 5.09 +/- 1.25 [95% CI 4.74-5.43], lidocaine 3.90 +/- 1.02 [95% CI 3.61-4.18], p <.001); immediately after procedure (placebo 4.03 +/- 0.89 [95% CI 3.78-4.27], lidocaine 3.16 +/- 0.67 [95% CI 2.97-3.34], p <.001); and 20 minutes after procedure (placebo 3.32 +/- 0.54 [95% CI 3.17-3.46], lidocaine 2.43 +/- 0.72 [95% CI 2.23-2.62], p <.001). No significant pain relief in nulliparous patients was obtained by the use of lidocaine (4.88 +/- 1.01 [95% CI 4.60-5.15], 3.88 +/- 0.86 [95% CI 3.64-4.11], 3.22 +/- 0.55 [95% CI 3.06-3.37], respectively; p >.05). Pain rated by the physician during, immediately after, and 20 minutes after the procedure was significantly different between the groups (p <.001), and a significant correlation was noted between the visual analog pain score and the patients' distress recorded by the physician (r = 0.816, r = 0.697, r = 0.676; p <.001, respectively). CONCLUSION: Intrauterine lidocaine seems to be effective in decreasing pain in parous women undergoing SIS.     

Clinical utility of saline solution infusion sonohysterography in a primary care obstetric-gynecologic practice

OBJECTIVE: The purpose of this study was to evaluate the role of saline solution infusion sonohysterography in clinical practice in patients with abnormal uterine bleeding.STUDY DESIGN: A prospective case-controlled study was conducted comparing two-dimensional transvaginal imaging with saline solution infusion sonohysterography, endometrial biopsies, and histologic evaluation after surgical procedures. One hundred twenty-four patients with abnormal uterine bleeding were scanned transabdominally and transvaginally. Patients with an increased endometrial thickness or a poorly defined endometrium underwent saline solution infusion sonohysterography. Sterile saline solution, 4 to 10 ml, was injected into the endometrial cavity under direct ultrasonographic visualization. Once the endometrium was expanded, the presence of polyps or myomas and the anterior and posterior endometrial thickness was assessed.RESULTS: Fifty-six patients were noted to have uterine leiomyomas. Eighteen patients had endometrial polyps. Five patients had simple endometrial hyperplasia. Two patients had atypical hyperplasia. No patients in this study had endometrial cancer. No complications occurred in this group of patients.CONCLUSION: Saline solution infusion sonohysterography is a procedure that aids the clinician in the management of abnormal uterine bleeding and may be more cost effective than traditional methods of evaluation.

Objectives

The current study aims to investigate the analgesic effect of oral hyoscine-N-butyl bromide (HBB) for alleviating pain during hysterosalpingography (HSG).

Lidocaine versus plain saline for pain relief in fractional curettage: a randomized controlled trial

OBJECTIVE: To compare the efficiency of lidocaine with that of plain saline for paracervical pain relief during fractional curettage. METHODS: This double-blind, randomized, controlled trial included 140 women who underwent fractional curettage. Seventy women were allocated to the lidocaine group and 70 to the plain saline group. The main outcome measure was the intensity of pain measured by visual analog scale during and after the procedure. RESULTS: The intensity of pain was significantly lower in the lidocaine group than in the plain saline group over the course of the procedure (P = .02), especially during fractional curettage. There were no serious adverse effects in this study. CONCLUSION: Lidocaine is more effective than plain saline for paracervical pain relief during fractional curettage. The anesthetic mechanisms of lidocaine are mechanical distention of tissue and peripheral nerve block.     

Prospective study of saline infusion sonohysterography in evaluation of perimenopausal and postmenopausal women with abnormal uterine bleeding

AIM: To evaluate saline infusion sonohysterography as an investigative modality in abnormal uterine bleeding in perimenopausal and postmenopausal women. METHODS: Fifty-eight patients, 52 perimenopausal and six postmenopausal women, with abnormal uterine bleeding were selected from the department of Obstetrics and Gynecology of Shrimati Sucheta Kriplani Hospital. After complete work-ups, transvaginal examinations were performed followed by sonohysterographies. The sensitivity, specificity, positive predictive values and negative predictive values were calculated for transvaginal sonography (TVS) and saline infusion sonohysterography as compared with findings of hysteroscopy/hysterectomy. RESULTS: Saline infusion sonohysterography was performed in 56 cases. It could not be done in one perimenopausal and one postmenopausal woman. Cavity was normal in 41 perimenopausal and five postmenopausal women. Ten women displayed abnormalities. Two had submucosal fibroids, two had intramural fibroids, one had fibroid polyp, three had endometrial polyps and two patients had endometrial growths. We found that TVS missed three endometrial polyps and one endometrial growth and led to mislabeling two intramural fibroids as submucosal. On comparing the sonohysterographic findings with those of hysteroscopy or hysterectomy, one endometrial polyp and one endocervical polyp was missed on sonohysterography, and one false positive growth was observed on sonohysterography. The sensitivity, specificity, positive predictive value and the negative predictive value of TVS were 84.8%, 79%, 82.4% and 82%, respectively. The sensitivity, specificity, positive predictive value and the negative predictive value of saline infusion sonohysterography were 94.1%, 88.5%, 91.4% and 92%, respectively. CONCLUSION: Saline infusion sonohysterography is a safe, convenient, time conserving, cost effective, easily accessible and acceptable investigative modality. It definitely enhances the diagnostic potential of TVS in assessment of endometrium and intracavitary pathologies.     

Efficacy of aromatherapy for reducing pain during labor: a randomized controlled trial

Background

Many strategies for labor pain management have been studied, including aromatherapy, which is a noninvasive, alternative medicine used as an adjunct for labor pain control. Nevertheless, the results were contradictory. Therefore, we conducted this study to determine the effectiveness of aromatherapy for reducing pain during labor.

Methods

A randomized controlled trial was carried out on Thai laboring primigravidae who were a low-risk singleton pregnancy undergoing vaginal delivery. All participants, both study and control group, received standard obstetric care. Aromatherapy was only provided to the study group during the first stage of labor. The women rated their pain intensity by rating scales at different stages of labor. The primary outcome was pain scores and the secondary outcomes were necessity of painkiller usage, labor time, aromatherapy-associated complications, route of delivery, and Apgar scores.

Results

A total of 104 women were recruited, 52 in each group. Baseline characteristics and baseline pain scores were comparable. The median pain score of latent and early active phase was lower in the aromatherapy group, 5 vs 6 and 7 vs 8, respectively. The mean differences of pain scores between latent and early active phase and the baseline were significantly lower in the aromatherapy group, 1.88 vs 2.6 (p = 0.010) and 3.82 vs 4.39 (p = 0.031), respectively. Late active phase pain scores and other perinatal outcomes were not significantly different.

Conclusion

Aromatherapy is helpful in reducing pain in latent and early active phase, and can probably be used as an adjunctive method for labor pain control without serious side effects.

     

Labor induction in women with an unfavorable Bishop score: randomized controlled trial of intrauterine Foley catheter with concurrent oxytocin infusion versus Foley catheter with extra-amniotic saline infusion with concurrent oxytocin infusion

OBJECTIVES: This study was undertaken to determine whether the addition of extra-amniotic saline infusion improves the efficacy of the Foley catheter in women undergoing cervical ripening and induction of labor with an unfavorable cervical examination. STUDY DESIGN: One hundred consenting women with a Bishop score less than 5 with singleton gestation, intact membranes, vertex presentation, who required induction of labor were randomly assigned to 2 groups: Foley alone (Foley, n=49) or to the Foley catheter with extra-amniotic saline infusion (EASI, 30 mL of NS per hour infused through the distal port of the Foley, n=51). All women received concurrent dilute oxytocin infusion per protocol. The primary analysis was intent to treat. Nonparametric tests were used as indicated. RESULTS: At randomization, the groups were well balanced for potential confounders including: parity, gestational age, prior cesarean delivery, preeclampsia, mean dilation, effacement, and Bishop score. There were no differences between the groups for time to delivery (Foley 17.7 +/- 10.5 hours vs EASI 17.4 +/- 11.7 hours, P=.9), the proportion of women delivered before 24 hours (Foley 41/49 [84%] vs EASI 39/51 [77%], P=.37) or cesarean rates (Foley 9/49 [17.7%] vs EASI 9/51 [18.4%], P=.92). There were also no differences in complications, including chorioamnionitis, endometritis, and neonatal morbidity. CONCLUSION: EASI does not increase the efficacy of cervical ripening and induction of labor with a Foley catheter and concurrent oxytocin infusion.     

Total dose iron dextran infusion versus oral iron for treating iron deficiency anemia in pregnant women: a randomized controlled trial

Study objective: To test safety, efficacy, and cost-effectiveness of total dose infusion (TDI) of low molecular weight (LMW) iron dextran for treatment of iron deficiency anemia (IDA) during pregnancy in comparison to oral ferrous fumarate.

Design: Prospective interventional randomized controlled trial (RCT). Design classification. Canadian Task Force II3.

Setting: Antenatal clinic and causality unit of a tertiary care referral facility and University Hospital.

Patients: A total 66 anemic pregnant women (hemoglobin level between 7–10?g/dl).

Intervention: Administration of a LMW iron dextran as a TDI (group A) or Oral iron ferrous fumarate 60?mg elemental iron three times daily (group B) followed by remeasurement of hemoglobin after 4 weeks.

Measures and main results: The main outcome measure was clinical and laboratory improvement of anemia after 4 weeks of starting the therapy. Both groups showed a significant clinical improvement of anemia 4 weeks post-therapy. However, the first improvement of symptoms was significantly faster in group A. Complete blood count (CBC) as well as all iron indices were improved in both groups after 4 weeks of therapy, but were significantly better in group A than B. Side effects in group B were mainly gastrointestinal (GIT) while one case of mild hypersensitivity to TDI and another one case of local reaction at the site of injection were reported in group A.

Conclusions: It is concluded that despite being equally effective in improving both clinical and laboratory evidence of IDA, TDI allows iron restoration with a single dose faster than oral iron therapy with a reasonable safety profile. It is a good example of office one-stop therapy. Nevertheless, noninvasive selfusage at home is a clear advantage of the cheaper oral iron therapy which makes it the first choice for treating IDA in the second and third trimesters of pregnancy in tolerable cases.

The use of non-nutritive sucking to decrease the physiologic pain response during neonatal circumcision: a randomized controlled trial

OBJECTIVE: The purpose of this research was to study the effects on the physiologic pain response of the neonate during circumcision with the use of a gloved human finger. STUDY DESIGN: This was a randomized controlled trial analyzing the effect of non-nutritive sucking (NNS) on pain response during circumcision. Term neonates were randomized to 2 groups. All infants received oral Tylenol and a dorsal penile nerve block (DPNB) before the circumcision. The study group was offered the addition of NNS before the DPNB and throughout the procedure. The primary outcome measured was heart rate during the circumcision. Other variables studied included crying time and salivary cortisol levels. Each circumcision was filmed to calculate pain profile scores using the Premature Infant Pain Profile. Variables were compared using Student t test, chi-square, and Wilcoxon test. A P value of < .05 was considered significant. RESULTS: Forty-four infants met inclusion criteria. Twenty-two infants were randomized to each arm. No difference in mean heart rate during the procedure was apparent. A significant decrease in crying time, 90-minute post-procedure salivary cortisol level, and post-penile clamping pain score was noted in the study group (all P values < .01). CONCLUSION: NNS significantly decreases some elements of measurable physiologic pain response of the neonate during circumcision. This method is a useful and inexpensive addition to DPNB and oral analgesics.     

Vaginal misoprostol for cervical priming before dilatation and curettage in postmenopausal women: a randomized controlled trial

AIM: To investigate the efficacy of vaginal misoprostol for cervical priming before dilatation and curettage in postmenopausal women. METHODS: Forty-four postmenopausal women with indication for dilatation and curettage were randomly assigned to receive either 400 micro g of misoprostol or placebo vaginally 6 h before dilatation and curettage. The main outcome measures were the number of women who required cervical dilatation, cervical width, time taken to dilate to Hegar 6 and other complications. RESULTS: The mean cervical diameter (4.59 millimeters in the misoprostol group vs 4.41 millimeters in the placebo group) was comparable between the two groups. A similar number of women in the misoprostol group and in the placebo group required cervical dilatation (12 vs 16, P = 0.35). The operative times for both groups were similar. The incidence of side-effects was comparable in both groups. There were two uterine perforations in the misoprostol group (2 vs 0). CONCLUSION: There was no significant benefit from applying 400 micro g vaginal misoprostol 6 h prior to dilatation and curettage in postmenopausal women.     

Transcervical Foley catheter with and without extraamniotic saline infusion for labor induction: a randomized controlled trial

OBJECTIVE: To compare the efficacy of transcervical Foley catheter alone (Foley) to transcervical Foley catheter with extraamniotic saline infusion for labor induction and cervical ripening in women with an unfavorable cervix. METHODS: This was a multicenter, randomized, controlled trial of women presenting for labor induction with a singleton, cephalic fetus, intact membranes, and unfavorable cervix (Bishop score 6 or less). Eligible women were randomly assigned to receive either Foley catheter alone or Foley catheter with extraamniotic saline infusion. All women received concurrent oxytocin administration. The primary study outcome was the induction-to-delivery interval. Secondary outcomes included cesarean delivery, maternal infectious outcomes, and immediate neonatal outcomes. Analysis was by intent to treat. RESULTS: One hundred eighty-eight women met eligibility criteria and were randomly assigned (Foley plus extraamniotic saline infusion, n=97; Foley, n=91). Baseline demographic characteristics, including parity, gestational age, and Bishop score were similar between the study groups. The median induction-to-delivery interval in the extraamniotic saline infusion arm (12.6 hours, interquartile range 9.3-18.8 hours) was similar to that in the Foley arm (13.4 hours, interquartile range 9.6-17.5 hours) (P=. 70). The proportion of women delivered by 24 hours was comparable between groups (delivery 24 hours, extraamniotic saline infusion 89.7%, Foley 87.9%, P=.70), as was the rate of cesarean delivery (Foley 18.7%, extraamniotic saline infusion 27.8%, P=.14). No significant differences were noted between the study groups with respect to rate of chorioamnionitis, endometritis, or immediate birth outcomes. CONCLUSION: In women with an unfavorable cervix, the addition of extraamniotic saline infusion to a transcervical Foley catheter does not improve efficacy for labor induction.

Diclofenac pyrrolidine versus Ketoprofen for the relief of pain from episiotomy: a randomized controlled trial

BACKGROUND: The treatment of pain from episiotomy or from tearing of perineal tissues during childbirth is often unapplied, although discomfort may be severe. We performed a randomized double-blind controlled trial to compare the effectiveness and side-effects of two analgesics in the management of postpartum perineal pain. Patient preference toward the two medications was also analyzed. METHODS: A total of 261 women were randomly assigned to receive either Diclofenac hydroxyethyl pyrrolidine (100 mg) (n = 133) or Ketoprofen (100 mg) (n = 128), both given orally every 12 hr up to 48 hr, as necessary. Inclusion criteria were vaginal birth with episiotomy and/or a second- to third-degree tear. Pain ratings were recorded before the administration of the drugs and at 1, 4, 12, and 24 hr after the first dose, according to a 10-cm visual-analog scale. Side-effects and overall opinion on the two treatments were assessed at 24 hr. RESULTS: Diclofenac hydroxyethyl pyrrolidine and Ketoprofen had similar analgesic properties in the first 24 hr postpartum [mean pain rating 3.1 +/- 1.8 and 3.4 +/- 2.0, mean number of doses in 24 hr 1.4 +/- 1.4 and 1.3 +/- 1.5, and proportion of treatment failures 12.8% (17/133) and 16.4% (21/128), respectively]. Significantly fewer subjects in the Diclofenac hydroxyethyl pyrrolidine group than in the Ketoprofen group experienced side-effects (6.8% versus 15.6%; p = 0.038) with an odd risk = 0.39(95% C.I. 0.16-0.95). There were no significant differences in overall patient satisfaction between the two groups. CONCLUSIONS: No main differences were found concerning the relief of pain between the two treatments. Diclofenac hydroxyethyl pyrrolidine may be the preferred choice because it is associated with less adverse reactions, together with a faster action in the relief of pain.
