Prolonged Duration of Peripheral Nerve Blockade in a Pediatric Patient with Charcot Marie Tooth Disease: A Case Report.

Charcot Marie Tooth disease is a common cause of pediatric peripheral neuropathy, which can lead to distal muscle wasting and weakness necessitating orthopedic procedures. We present an eleven-year-old male with Charcot Marie Tooth disease who received peripheral nerve blocks for ankle surgery, with a total dose of 1.75 mg/kg of bupivacaine 0.25%. Upon follow-up, it was identified that the sensory blockade did not resolve until thirty-six hours, postoperatively. There were no noted long-term sequalae on surgical follow-up. If a patient with Charcot Marie Tooth receives a peripheral nerve block, the patient should receive close short- and long-term follow-up to monitor for block complication or disease exacerbation.

Pregnancy complications and loss: an observational survey comparing anesthesiologists and obstetrician-gynecologists.

OBJECTIVE: While there is increasing information regarding the occupational risks to pregnant physicians, there is inconsistent and limited subspecialty data. Physicians may be at increased risk for pregnancy complications due to occupational exposure, long work hours, nightshifts, and physical/mental demands. Additionally, little is known regarding the education physicians receive pertaining to pregnancy risks respective to their specialties as well as departmental/institutional support for pregnancy loss or complication. Therefore, a survey was developed and distributed across multiple academic sites to ascertain if there is an inherent occupation-associated risk of pregnancy complication(s) and/or pregnancy loss for anesthesiologists (ANES) when compared to obstetrician/gynecologists (OB/GYN). METHODS: A specialty-specific survey was distributed electronically to attending ANES and OB/GYN, via departmental listservs at six participating academic medical centers. Responses were collected from March to October 2022 and included demographic information, practice characteristics, education about pregnancy risks and details of pregnancy complications and loss. The primary comparison between specialty groups was the occurrence of at least one pregnancy complication and/or loss. Logistic regression was used to evaluate specialty outcome associations. Additionally, complication rates and types between specialties were compared using univariate and multivariable models. RESULTS: The survey was distributed to 556 anesthesiology and 662 obstetrics-gynecology faculty members with 224 ANES and 168 OB/GYN respondents, yielding an overall 32.2% response rate. Of the survey respondents, 103 ANES and 116 OB/GYN reported at least one pregnancy. Demographics were similar between the two cohorts. ANES had higher gravidity and parity relative to OB/GYN and tended to be earlier in their career at first pregnancy (p = .008, <.001, and .043, respectively). The rate of any pregnancy complication, including loss, was similar between specialties (65.1% (67/103) vs. 65.5% (76/116), p = .942). Of the respondents reporting at least one pregnancy, 56.7% of ANES and 53.9% of OB/GYN experienced a complication while at work. Obstetrician-gynecologists had higher use of reproductive assistance (28% (47/116) vs. 11% (20/103), p < .001). There were no notable differences between cohorts for complications, prematurity, and neonatal intensive care admission. Forty-one percent (161/392) of total respondents recalled learning about occupational risks to pregnancy, and ANES were more likely than OB/GYN to have recalled learning about these risks (121/224 (54%) and 40/168 (23.8%), respectively, p < .001). CONCLUSIONS: ANES and OB/GYN had similar risks for pregnancy complications and loss. Anesthesiologists were more likely to recall receiving education regarding occupational risk to pregnancy, though fewer than half of all survey respondents recalled learning about these risks. Our survey results are similar to the previously identified higher rate of pregnancy complications and loss in female physicians while uncovering areas of potential knowledge gaps for which institutions and practices could strive to improve upon. More research is needed to examine the relationship between occupation and pregnancy risk pertaining to female physicians with the goal being to identify modifiable risk factors.

Regional anesthesia for ambulatory pediatric penoscrotal procedures.

BACKGROUND/PURPOSE: Pediatric urology procedures are amongst the most commonly performed in children. The need for proactive treatment of pain is essential for optimal patient care. Current guidelines recommend the routine use of regional anesthesia in children as appropriate unless contraindicated. Given the commonality of urologic procedures in children, it is essential to understand the indications for and the utility of regional anesthesia. METHODS: The current literature was searched using PubMed as the primary platform. Search words included 'dorsal penile nerve block,' 'pudendal nerve block,' 'ring block,' 'spinal anesthesia,' and 'caudal,' along with 'pediatric', 'circumcision,' 'hypospadias,' 'urology', and 'urological surgery' as part of the keywords of the search. RESULTS: The articles resulting from the literature search were reviewed for content, clarity and study design by two co-authors, and agreement determined the incorporation into the review. Additionally, a detailed description of study design, regional anesthetic technique, local anesthetic(s) used, and outcomes of each study referenced was incorporated into the supplemental table. CONCLUSION: Given the variance in block technique and local anesthetic choice amongst the current reported studies in the literature, it is difficult to truly compare and infer superiority of the regional anesthetic choices for ambulatory penoscrotal procedures. When choosing a regional anesthetic technique, careful consideration must be placed on block coverage, severity of expected pain and surgical duration of the procedure, type and dose of local anesthetic, as well as the patient's past medical history and anatomy. Moreover, the regional block chosen should result from a thorough preoperative discussion between the surgeon and the anesthesiologist.

Development and Usability Testing of the Society for Pediatric Anesthesia Pedi Crisis Mobile Application.

When life-threatening, critical events occur in the operating room, the fast-paced, high-distraction atmosphere often leaves little time to think or deliberate about management options. Success depends on applying a team approach to quickly implement well-rehearsed, systematic, evidence-based assessment and treatment protocols. Mobile devices offer resources for readily accessible, easily updatable information that can be invaluable during perioperative critical events. We developed a mobile device version of the Society for Pediatric Anesthesia 26 Pediatric Crisis paper checklists-the Pedi Crisis 2.0 application-as a resource to support clinician responses to pediatric perioperative life-threatening critical events. Human factors expertise and principles were applied to maximize usability, such as by clustering information into themes that clinicians utilize when accessing cognitive aids during critical events. The electronic environment allowed us to feature optional diagnostic support, optimized navigation, weight-based dosing, critical institution-specific phone numbers pertinent to emergency response, and accessibility for those who want larger font sizes. The design and functionality of the application were optimized for clinician use in real time during actual critical events, and it can also be used for self-study or review. Beta usability testing of the application was conducted with a convenience sample of clinicians at 9 institutions in 2 countries and showed that participants were able to find information quickly and as expected. In addition, clinicians rated the application as slightly above "excellent" overall on an established measure, the Systems Usability Scale, which is a 10-item, widely used and validated Likert scale created to assess usability for a variety of situations. The application can be downloaded, at no cost, for iOS devices from the Apple App Store and for Android devices from the Google Play Store. The processes and principles used in its development are readily applicable to the development of future mobile and electronic applications for the field of anesthesiology.
