The effectiveness of a multidisciplinary, team-based approach to cesarean hysterectomy in modern obstetric practice

Peripartum Ηysterectomy: A Four-Year Obstetric and Anesthetic Experience in a Tertiary Referral Hospital in Greece

Background

Although peripartum hysterectomy (PH) is a life-saving procedure in cases of abnormal placentation and postpartum hemorrhage, it can be associated with major obstetric and anesthetic complications. This retrospective study aimed to evaluate the incidence, etiology, perioperative anesthetic and obstetric management, complications, and fetal outcomes in women undergoing PH in a single tertiary referral hospital in Greece.

Methodology

This was a retrospective analysis of medical records of women who underwent emergency or elective PH in our hospital between January 2015 and December 2018.

Results

During the study period, 69 women who underwent a PH were identified. The incidence rate of elective and emergency PH was 4 and 1.2 per 1,000 deliveries, respectively. The main indication for PH was abnormal placentation (81.2%), followed by uterine atony (13%). Conversion to general anesthesia (GA) was performed in 21 (30.4%) cases.

Conclusions

This study showed a high prevalence of PH in our hospital compared to high-income countries. A neuraxial-only technique may be a safe alternative in individual cases of abnormal placentation. Conversion to GA can be reserved for complex surgical cases when massive hemorrhage is anticipated and, if possible, after the neonate has been delivered.

Preparing Perinatal Nurses for Obstetric OR Emergencies by Using Simulations

A cesarean hysterectomy (CH) is an emergency procedure that can save a woman's life in the event of postpartum hemorrhaging. If the CH is anticipated, it can take place in the general OR; however, more complex patients with multiple comorbidities are undergoing cesarean deliveries, resulting in unanticipated CHs and emergent procedures occurring in the obstetric OR. Many perinatal nurses believe they are not properly trained to provide the level of perioperative care required during a CH. Perinatal nurse leaders implemented a perinatal perioperative simulation program to address this knowledge gap. Feedback from perinatal nurses after completing the simulation revealed they gained a comprehensive understanding of the flow of the procedure and the instrumentation needed to perform it. The simulation also improved communication and leadership skills in the obstetric OR. Simulations may help perinatal nurses provide safer, higher quality care when a delivery develops into a high-risk operative procedure.

Postpartum hemorrhage: Anesthesia management

As major stakeholders in the labor and delivery suite, obstetric anesthesiologists are frequently called upon to provide their unique skill sets and expertise to the management of postpartum hemorrhage, whether anticipated or not. Essential contributions of the anesthesia team ideally begin in the antenatal period with referral of women at high risk of postpartum hemorrhage to an outpatient obstetric anesthesia clinic where a tailored plan for both urgent or scheduled delivery for women with an anticipated complex delivery can be formulated. Maternal safety can be greatly improved if comorbidities are identified early and strategies to address these issues are proposed and known by the obstetric anesthesia team. Participation of the obstetric anesthesiology team is crucial in the development of systematic approaches that are customized to each institution and should comprise the creation and dissemination of algorithms and guidelines that are anesthesia specific, including detailed protocols for the labor and delivery unit and operating rooms, at large. Because management of postpartum hemorrhage requires a coordinated team effort, and may not always be planned, the anesthesia team should be prepared at all times to provide the appropriate anesthetic management and advanced cardiovascular support. The involvement of the anesthesia team should not only be limited to the immediate intrapartum period, but should also extend to the postpartum period where adequate anesthetic/analgesic plans will enhance maternal safety and recovery.

Abnormal placentation

The term "morbidly adherent placenta" has recently been introduced to describe the spectrum of disorders including placenta accreta, increta and percreta. Due to excessive invasion of the placenta into the uterus there is associated significant maternal morbidity and mortality. Most significant risk factors for morbidly adherent placenta include history of prior cesarean delivery as well as placenta previa in the current pregnancy. Ultrasound remains the gold standard for antenatal diagnosis, however, in recent years MRI has assisted in identifying complex parametrial involvement. Optimizing maternal and neonatal outcomes involves early prenatal diagnosis, a multi-disciplinary team-based approach, and referral to an experienced center.

Multidisciplinary Approach to Placenta Percreta: An Observational Case Study

Abnormal placental implantations can result in postpartum hemorrhage and poor outcomes. With proper diagnosis and preplanning, complications can be minimized and aligned with maternal wishes of abstaining from blood and blood product transfusions.

Crisis Teams for Obstetric Patients

An obstetric-specific crisis team allows institutions to optimize the care response for patients with emergent maternal or fetal needs. Characteristics of optimal obstetric rapid response teams are team member role designations; streamlined communication; prompt access to resources; ongoing education, rehearsal, and training; and continual team quality analysis. The outcomes must be incorporated into team responses and reinforced in training. Team response provides a key resource to reassure staff, physicians, and patients that prompt crisis care is only a single call away. Data show that team activation is common, improves the care process, and has promise to improve outcomes.
