Management of postpartum hemorrhage (PPH): algorithm of the interdisciplinary D-A-CH consensus group PPH (Germany – Austria – Switzerland)

Postpartum hemorrhage (PPH) is one of the main causes of maternal deaths even in industrialized countries. It represents an emergency situation which necessitates a rapid decision and in particular an exact diagnosis and root cause analysis in order to initiate the correct therapeutic measures in an interdisciplinary cooperation. In addition to established guidelines, the benefits of standardized therapy algorithms have been demonstrated. A therapy algorithm for the obstetric emergency of postpartum hemorrhage in the German language is not yet available. The establishment of an international (Germany, Austria and Switzerland D-A-CH) "treatment algorithm for postpartum hemorrhage" was an interdisciplinary project based on the guidelines of the corresponding specialist societies (anesthesia and intensive care medicine and obstetrics) in the three countries as well as comparable international algorithms for therapy of PPH.The obstetrics and anesthesiology personnel must possess sufficient expertise for emergency situations despite lower case numbers. The rarity of occurrence for individual patients and the life-threatening situation necessitate a structured approach according to predetermined treatment algorithms. This can then be carried out according to the established algorithm. Furthermore, this algorithm presents the opportunity to train for emergency situations in an interdisciplinary team.

Recombinant human factor VIIa prevents hysterectomy in severe postpartum hemorrhage: single center study

Abstract Objective: To evaluate the effectiveness of human recombinant activated factor VII (rhFVIIa, NovoSeven) in avoiding hysterectomy postpartum in the management of severe postpartum hemorrhage (PPH). Methods: We performed a prospective cohort study at our university tertiary care center. Patients with severe post partum hemorrhage (blood loss >2000 mL) and failed medical and uterus-preserving surgical management, were treated with intravenous bolus administration of rhVIIa. Main outcome measures were cessation of bleeding, postpartum hysterectomy and thromboembolic events. Results: In 20/22 patients included, PPH was caused primarily by uterine atony, including 7 (32%) with additional lower genital tract lesion; in two women, it was due to pathologic placentation (placenta increta, 9%). One case of amniotic fluid embolism and one woman with uterine inversion were included. Recombinant hFVIIa was successful in stopping the PPH and in preventing a hysterectomy in 20/22 women (91%). The remaining two patients with persistent bleeding despite rhFVIIa treatment, who underwent postpartum hysterectomy, had placenta increta. No thromboembolic event was noticed. Conclusions: This study describes the largest single center series of rhFVIIa treatment for fertility preservation in severe postpartum hemorrhage published to date. Our data suggest that administration of rhFVIIa is effective in avoiding postpartum hysterectomy after conservative medical and surgical measures have failed. Although randomized studies are lacking, rhFVIIa should be considered as a second-line therapeutic option of life-threatening postpartal bleeding, in particular if preservation of fertility is warranted and hysterectomy is to be avoided.

The Hayman technique: a simple method to treat postpartum haemorrhage

Of the several uterine compression sutures described in more recent years to treat postpartum haemorrhage (PPH), the Hayman suture offers the potential advantages that can be applied faster and easier, avoiding the performance of a lower segment hysterotomy when PPH follows a vaginal delivery. Data on efficacy and safety are limited, and long-term follow-up information are lacking. We report our experience with the Hayman suture in 11 consecutive women with massive PPH. Of these, ten were successfully treated without further interventions. One woman ultimately required a hysterectomy. Postoperative course was uncomplicated in all the cases. The median follow-up time was 11 months (range 1-19). One woman conceived spontaneously 10 months after the procedure. Our results suggest that the Hayman suture is an effective and safe treatment for PPH.

Diagnosis and treatment of peripartum bleeding

Severe peripartum hemorrhage (PPH) contributes to maternal morbidity and mortality and is one of the most frequent emergencies in obstetrics, occurring at a prevalence of 0.5-5.0%. Detection of antepartum risk factors is essential in order to implement preventive measures. Proper training of obstetric staff and publication of recommendations and guidelines can effectively reduce the frequency of PPH and its resulting morbidity and mortality. Therefore, an interdisciplinary expert committee was formed, with members from Germany, Austria, and Switzerland, to summarize recent scientific findings. An up-to-date presentation of the importance of embolization and of the diagnosis of coagulopathy in PPH is provided. Furthermore, the committee recommends changes in the management of PPH including new surgical options and the off-label use of recombinant factor VIIa.

The paradox of adult respiratory distress syndrome in neonates

Six full-term newborn infants are described who suffered from severe adult respiratory distress syndrome (ARDS). The triggering event was intrauterine/perinatal asphyxia in five, and group B streptococcal (GBS) septicemia in three. All had severe respiratory distress/failure and were ventilated mechanically with high concentrations of inspired oxygen and positive end-expiratory pressure. Radiography of the chest showed dense bilateral consolidation with air bronchograms and reduced lung volume. Persistent pulmonary hypertension (PPH) was documented in all cases. The coincidence of ARDS and PPH rendered respiratory management extremely difficult. For this reason high-frequency ventilation was instituted in all patients in order to improve CO2 elimination and induce respiratory alkalosis. Acute complications of respiratory therapy were encountered in five patients (pneumothorax, pulmonary interstitial emphysema, pneumopericardium). Three infants died (irreversible septic shock, progressive severe hypoxemia, and sudden cardiac arrest) after 17, 80, and 175 h of life. Histologic examination of the lungs was possible in all fatal cases and revealed typical changes of acute to subacute stages of ARDS. Three infants survived, the mean time of mechanical respiratory support being 703 h. Two patients were still dependent on oxygen after 1 month of life, and all survivors had increased interstitial markings and increased lung volumes on their chest roentgenograms at this time.
