Dr. Allana Munro and Dr. Ronald George are two obstetric anesthesia experts whose research is focused on labor analgesia. Two years ago, they demonstrated that “achieving desired pain relief” is of utmost importance to our patients. The question remains: How can we safely achieve this while minimizing workload and side effects? In this episode, they discuss their study titled “An Innovative Approach to Determine Programmed Intermittent Epidural Bolus Pump Settings for Labor Analgesia: A Randomized Controlled Trial.” Using the response surface methodology, they identified optimal settings for the programmed intermittent epidural bolus pump (PIEB) that maximize maternal satisfaction, minimize clinician-administered boluses, and balance PCEA boluses delivered to those requested.

In this episode, Dr. de Carvalho discusses his article, Efficacy and safety of ultrasound-guided versus landmark-guided neuraxial puncture: a systematic review, network meta-analysis and trial sequential analysis of randomized clinical trials. Dr. de Carvalho’s work reiterates that using ultrasound-guided neuraxial anesthesia results in a more efficient neuraxial placement. Ultrasound-guided neuraxial use results in fewer needle attempts and redirections and may improve patient satisfaction. Besides, his works demonstrate that ultrasound benefits both patients with normal and abnormal anatomy.

In this episode, Dr. Lawrence Tsen discusses the findings of his paper on Labor Analgesia Initiation with Dural Puncture Epidural (DPE) Versus Conventional Epidural Techniques. The paper presents a randomized biased-coin sequential allocation trial to determine the effective dose for 90% of patients of Bupivacaine. We explore the benefits of using the DPE technique, if any, along with criticisms from some experts. Additionally, we delve into whether DPE techniques can improve analgesia and the mechanisms behind it. These are just a few of the topics covered in this podcast.

In this episode, Dr. Holly Ende discusses her article, Implementation of an Epidural Rounding Reminder in the Electronic Medical Record Improves Performance of Standardized Patient Assessments during Labor.
Dr. Ende’s work underscores the necessity of regular assessments of the effectiveness of neuraxial labor analgesia. This proactive approach is crucial for the timely identification of malfunction, ensuring the best possible outcomes for patients.
