Recent advances of simulation in obstetric anesthesia

The importance of simulation-based multi professional training in obstetric anesthesia: an update

PURPOSE OF REVIEW

Simulation-based training remains an integral component of medical education by providing a well tolerated, controlled, and replicable environment for healthcare professionals to enhance their skills and improve patient outcomes. Simulation technology applied to obstetric anesthesiology continues to evolve as a valuable tool for the training and assessment of the multidisciplinary obstetric care team.

RECENT FINDINGS

Simulation-based technology has continued to play a role in training and assessment, including recent work on interdisciplinary communication, recognition, and management of obstetric hemorrhage, and support in the low or strained resource setting. The COVID-19 pandemic has accelerated the evolution of simulation-based training away from a reliance on in-situ or high-fidelity manikin-based approaches toward an increasing utilization of modalities that allow for remote or asynchronous training.

SUMMARY

The evolution of simulation for interdisciplinary training and assessment in obstetric anesthesia has accelerated, playing a greater role in aspects of communication, management of hemorrhage and supporting low or strained resource settings. Augmented reality, virtual reality and mixed reality have advanced dramatically, spurred on by the need for remote and asynchronous simulation-based training during the pandemic.

Updates on Simulation in Obstetrical Anesthesiology Through the COVID-19 Pandemic

Simulation has played a critical role in medicine for decades as a pedagogical and assessment tool. The labor and delivery unit provides an ideal setting for the use of simulation technology. Prior reviews of this topic have focused on simulation for individual and team training and assessment. The COVID-19 pandemic has provided an opportunity for educators and leaders in obstetric anesthesiology to rapidly train health care providers and develop new protocols for patient care with simulation. This review surveys new developments in simulation for obstetric anesthesiology with an emphasis on simulation use during the COVID-19 pandemic.

Single-center task analysis and user-centered assessment of physical space impacts on emergency Cesarean delivery

Cesarean delivery is the most common surgery performed in the United States, accounting for approximately 32% of all births. Emergency Cesarean deliveries are performed in the event of critical maternal or fetal distress and require effective collaboration and coordination of care by a multidisciplinary team with a high level of technical expertise. It is not well understood how the physical environment of the operating room (OR) impacts performance and how specialties work together in the space.

General anesthesia for emergency cesarean delivery: simulation-based evaluation of residents

Introduction

Decreased rates of General Anesthesia (GA) for Cesarean Section (C-section) create a learning problem for anesthesia trainees. In this context, training the management of GA for C-section using simulation techniques allows a safe environment for exposure, learning, performance improvement, and capability retention.

Objective

Analyze anesthesia residents’ performance regarding a simulated clinical case of GA for emergency C-section and identify specific deficits in skill acquisition.

Methods

Between 2015 and 2018, we evaluated the performance of 25 anesthesiology residents challenged by a simulated clinical case of GA for emergency C-section after the conclusion of the obstetric anesthesia rotation. Each resident performed the clinical case once followed by the assessment of their performance. Final scores were given according to the completion rate of 14-tasks, going from 0% to 100%. Two study groups were considered according to residency year for subsequent comparison of results (Group 1, second and third residency years and Group 2, fourth and fifth residency years).

Results and discussion

Mean score was 64.29% ± 13.62. Comparatively, Group 1 obtained a higher score than Group 2 (70.63% ± 14.02 vs. 60.27% ± 11.94), although with no statistically significant difference (p = 0.063). The tasks most frequently accomplished were opioid administration (100%), rapid sequence technique (100%), pre-oxygenation (92%), gastric content aspiration prophylaxis (84%), and previous clinical history (84%). Conversely, the tasks less frequently accomplished were confirming presence of pediatrician (64%), oxytocin administration (56%), PONV prophylaxis (56%), and preoperative airway assessment (48%).

Conclusion

The performance of the residents observed in this study was comparable to results previously published. The final score did not depend on the residency year.

The Current Role of General Anesthesia for Cesarean Delivery

Purpose of the Review

The use of general anesthesia for cesarean delivery has declined in the last decades due to the widespread utilization of neuraxial techniques and the understanding that neuraxial anesthesia can be provided even in urgent circumstances. In fact, the role of general anesthesia for cesarean delivery has been revisited, because despite recent devices facilitating endotracheal intubation and clinical algorithms, guiding anesthesiologists facing challenging scenarios, risks, and complications of general anesthesia at the time of delivery for both mother and neonate(s) remain significant. In this review, we will discuss clinical scenarios and risk factors associated with general anesthesia for cesarean delivery and address reasons why anesthesiologists should apply strategies to minimize its use.

Recent Findings

Unnecessary general anesthesia for cesarean delivery is associated with maternal complications, including serious anesthesia-related complications, surgical site infection, and venous thromboembolic events. Racial and socioeconomic disparities and low-resource settings are major contributing factors in the use of general anesthesia for cesarean delivery, with both maternal and perinatal mortality increasing when general anesthesia is provided. In addition, more significant maternal pain and higher rates of postpartum depression requiring hospitalization are associated with general anesthesia for cesarean delivery.

Summary

Rates of general anesthesia for cesarean delivery have overall decreased, and while general anesthesia no longer is a contributing factor to anesthesia-related maternal deaths, further opportunities to reduce its use should be emphasized. Raising awareness in identifying situations and patients at risk to help avoid unnecessary general anesthesia remains crucial.

Job role and stress influence student movement during postpartum haemorrhage simulation: an exploratory study

Introduction

Postpartum haemorrhage is the leading cause of maternal death. Healthcare simulations are an educational tool to prepare students for infrequent high-risk emergencies without risking patient safety. Efficiency of movement in the simulation environment is important to minimize the risk of medical error. The purpose of this study was to quantify the movement behaviours of the participants in the simulation and evaluate the relationship between perceived stress and movement.

Methods

N=30 students participated in 10 high-fidelity medical simulations using an adult patient simulator experiencing a postpartum haemorrhage. The participants completed the State-Trait Anxiety Inventory prior to the simulation to measure perceived stress. Physical movement behaviours included walking around the simulation, time spent at bedside, arm movements, movements without purpose, looking at charts/vitals and total movement.

Results

Midwife (MW) students spent significantly more time walking (p=0.004) and looking at charts/vitals (p=<0.001) and significantly less time at bedside (p=<0.001) compared to obstetric (OB) students. The MW students demonstrated significantly more total movements compared to the OB students (p=<0.001). There was a significant, moderate, positive relationship between perceived stress and total movement during the simulation for the MW group (r=0.50, p=0.05). There was a trend for a moderate, positive relationship between perceived stress and total movement during the simulation for the OB group (r=0.46, p=0.10).

Conclusions

Physical movement during a simulation varies by job role and is influenced by perceived stress. Improved understanding of physical movement in the simulation environment can improve feedback, training and environmental set-up.

Simulation in obstetric anesthesia: an update

PURPOSE OF REVIEW

Simulation training (crew resource management training and scenario training) has become an important tool in the education of anesthesiologists. This review summarizes recent research performed in this area, focusing more specifically on obstetric anesthesia.

RECENT FINDINGS

Simulation training is becoming more integrated in the modern education of anesthesiologists. Research regarding the most effective way to perform simulation training in terms of learning outcomes and long-term skill retention has started to appear. Scenarios which are played independently and that allow for simulated mortality, as well as relaxation techniques before debriefing might have positive effects in this regard. Furthermore, simulation has been investigated as a tool to improve patient safety in low-resource settings. In addition, simulation training in the domain of obstetrics has been rapidly expanding and has an important role in this field of medicine as well.

SUMMARY

Simulation training has acquired a central role in modern education of anesthesiologists. Further research regarding elements to optimize simulation training in terms of learning outcomes and long-term skill retention is desirable. In addition, little data exist concerning the effect of simulation training on possible improvement of patient outcomes in anesthesia.

Benefits of Screen-Based Postpartum Hemorrhage Simulation on Nontechnical Skills Training: A Randomized Simulation Study

BACKGROUND

Postpartum hemorrhage (PPH) is the leading cause of maternal death in the world. Nontechnical skills (NTS), such as communication and teamwork, are critical for efficient management of this obstetric emergency. Specific scenarios were designed on a screen-based simulator to train NTS. This study aimed to evaluate the impact of training midwives for NTS with a PPH screen-based simulation.

METHODS

A total of 24 midwives participated in the study. They were randomized in 2 groups: the NTS group (n = 12) performed 3 screen-based scenarios designed to train NTS and the control group (n = 12) performed 3 basic scenarios of the screen-based simulation without the NTS training. A structured interview followed the simulation. On the same day, each trainee underwent individually an evaluation on a PPH high-fidelity simulation scenario. Three experts, blinded to the study arm, assessed the NTS with the Anesthetists Non-Technical Skills (ANTS) score.

RESULTS

Midwives from the NTS group achieved higher median scores in each dimension of the ANTS score: task management (4 vs. 2/4, P < 0.0001), team working (4 vs. 2/4, P < 0.0001), situation awareness (4 vs. 2.7/4, P < 0.0001), and decision-making (4 vs. 2/4, P < 0.0001). The median value of the total ANTS score was higher in the NTS group than in the control group (15.5 vs. 8/16, P < 0.0001).

CONCLUSIONS

Our study highlights that training with a NTS screen-based simulation, with specific scenarios and debriefing, leads to higher midwives' nontechnical skills performance during simulated postpartum hemorrhage.
