A Novel Technique Using Ultrasonic Shears Versus Traditional Methods of Reduction of Bilateral Labia Minora Hypertrophy: A Retrospective Case-Control Study.

INTRODUCTION: To compare the clinical outcomes of bilateral labia minora hypertrophy reduction using ultrasonic shears versus traditional methods. MATERIALS AND METHODS: In this retrospective study, we evaluate the surgical outcomes of 11 women who underwent bilateral labia minora hypertrophy reduction using ultrasonic shears to 14 women who underwent the same procedure using various traditional methods between January 1, 2015 and February 29, 2020 in a single center. The primary outcomes evaluated are total operative time, estimated blood loss, and postoperative pain. Secondary outcomes include postoperative complications and total admission time. The statistical analyses used were exact Wilconxon Rank and Fisher's exact test. RESULTS: 25 total bilateral labiaplasty procedures were included in the analysis. 11 procedures were performed using ultrasonic shears and 14 were performed using traditional methods. The mean reduction operative time for the ultrasonic shears technique when compared with traditional methods was 43.25 minutes (22.82 minutes versus 66.07 minutes, P = .0002). A statistically significant but non-clinically significant difference in estimated blood loss was noted. No statistically significant differences existed with postoperative pain score, total admission time, or postoperative complications. CONCLUSIONS: Ultrasonic shears significantly reduce the time needed for the reduction of bilateral labia minora hypertrophy and therefore should be considered by surgeons as a useful tool in increasing the efficiency of this procedure.

Development of In-situ Simulation Lab for Training Gynecology Residents in Basic Laparoscopic and Hysteroscopic Operative Skills.

INTRODUCTION: Mounting evidence suggests that practice on simulators leads to improved operative skills and patient safety. With restrictions on resident work hours resulting in less exposure to procedures, simulation is the key to developing operative skills during residency and beyond. Residency programs struggle with implementing a simulation program due to timing and availability of residents. Despite having a large centralized simulation space at our institution, we identified lack of dedicated gynecologic simulation curriculum and simulator accessibility as our greatest barriers to utilizing simulation training in gynecology resident education. We sought to design a space within the resident work area dedicated to gynecologic simulation training with specific curriculum and objectives for each work station based on residency year level. METHODS: We created four workstations in a room within the Ob/Gyn clinic, in close proximity to the resident offices. Two virtual reality simulators, the LapVR (CAE, Montreal, Canada) ($84,996.00) and Simbionix Hystsim (3D Systems, (formerly Simbionix), CO, USA) ($95,741.10), were acquired from our institution's simulation center and placed in this training space to allow for enhanced resident access. The two other work stations consisted of an FLS trainer box and monitor ($1580) and another low fidelity laparoscopic box trainer and monitor ($450). Specific objectives for each station with corresponding evaluation checklists were written for each residency year level. Dedicated time to meet the written objectives was given to residents each week during their benign gynecology rotation. Supervision and assistance with task completion was provided by staff mentors assigned during those shifts. RESULTS: Residents who had this simulation lab available to them during their gynecology rotation participated in a minimum of seven hours of simulation time in addition to the time they spent on their own in the lab. These residents felt this was a meaningful increase in the amount of laparoscopic and hysteroscopic simulation exposure by having access to this in-situ GYN Simulation Training Laboratory with a defined gynecologic curriculum. Multiple staff members also took advantage of the simulation lab to practice their skills as well. CONCLUSIONS: We created an in-situ Gyn Simulation Training Lab that allowed for both improved accessibility by the residents and ease of implementation of simulation curriculum into pre-existing resident didactic time. It is our opinion that the time residents spend engaged in surgical simulation will improve surgical skills and confidence thereby enhancing patient safety. Additionally, the creation of this in situ simulation lab assists in meeting the Accreditation Council for Graduate Medical Education (ACGME) requirements for incorporation of simulation into OB/GYN resident education.

Effect of pain and analgesia on compensatory reserve.

BACKGROUND: The measurement of the body's capacity to compensate for reduced blood volume can be assessed with a compensatory reserve measurement (CRM). The CRM, which is calculated from changes in features of the arterial waveform, represents the integration of compensatory mechanisms during states of low tissue perfusion and oxygenation, such as hemorrhage. This study was designed to test the hypothesis that pain which activates compensatory mechanisms and analgesia that result in reduced blood pressure are associated with lower compensatory reserve. This study evaluated CRM in obstetric patients during labor as pain intensity increased from no pain to severe pain and compared CRM before and after epidural anesthesia. METHODS: CRM was calculated from a finger pulse oximeter placed on the patient's index finger and connected to the DataOx monitor in healthy pregnant women (n = 20) before and during the active labor phase of childbirth. RESULTS: As pain intensity, based on an 11-point scale (0, no pain; 10, worst pain), increased from 0 to 8.4 ± 0.9 (mean ± SD), CRM was not affected (81 ± 10% to 82 ± 13%). Before analgesia, CRM was 84 ± 10%. CRM at 10 minutes, 20 minutes, 30 minutes, 40 minutes, 50 minutes, and 60 minutes after analgesia was 82 ± 11%, 83 ± 14%, 83 ± 15%, 86 ± 12%, 89 ± 9%, and 87 ± 10%, respectively. There was a transient 2% reduction followed by a 5% increase in CRM from before to after epidural anesthesia (p = 0.048). Pain scores before and after analgesia were 7 ± 2 and 1 ± 1, respectively (p < 0.001). CONCLUSION: These results indicate that pain and analgesia contribute minimally, but independently to the reduction in compensatory reserve associated with trauma and hemorrhage. As such, our findings suggest that analgesia can be safely administered on the battlefield while maintaining the maximal capacity of mechanisms to compensate for blood loss. LEVEL OF EVIDENCE: Diagnostic study, level II.
