RESUMO
OBJECTIVE: To characterize penile arterial and venous blood flow in association with caudal block. METHODS: A prospective observational study was conducted in children undergoing primary circumcision at Texas Children's Hospital between September 10, 2020 and November 23, 2021. The penile artery and venous flow velocity were assessed using Doppler ultrasound pre and post caudal block under state-state anesthetic depth. RESULTS: Ten healthy patients were included in the study with a mean age and weight of 1.3 years and 10.7 kg, respectively. There was no significant difference in mean penile arterial blood flow velocity 0.18 m/s, (95% confidence interval: -1.55 to 1.92; P = .81) or mean dorsal penile vein flow velocity 0.11 m/s (95% confidence interval: -1.12 to 1.33; P = .84) prior to and following caudal block in our pediatric cohort. there was no correlation in the direction of change between the arterial flow and venous flow from before and after caudal block (R2 = 0.03). CONCLUSION: We did not identify an association between penile arterial or venous blood flow and performance of a caudal block in children undergoing circumcision.

BACKGROUND: Obstructive sleep apnea is a risk factor for respiratory depression following opioid administration as well as opioid-induced hyperalgesia. Little is known on how obstructive sleep apnea status is associated with central ventilatory depression in pediatric surgical patients given a single dose of fentanyl. METHODS: This was a single-center, prospective trial in children undergoing surgery requiring intubation and opioid administration. Sixty patients between the ages of 2-8 years presenting for surgery at Texas Children's Hospital were recruited. Twenty non-obstructive sleep apnea controls and 30 patients with moderate to severe obstructive sleep apnea met inclusion criteria. Following induction of general anesthesia and establishment of steady-state ventilation, participants received 1 mcg/kg intravenous fentanyl. Ventilatory variables (tidal volume, respiratory rate, end-tidal CO2 , and minute ventilation) were assessed each minute for 10 min. The primary outcome was the extent of opioid-induced central ventilatory depression over time by obstructive sleep apnea status when compared with baseline values. Secondary aims assessed the impact of demographics and SpO2 nadir on ventilatory depression. RESULTS: We found no significant difference in percent decrease in respiratory rate (38.1% and 37.1%; p = .950), tidal volume (6.4% and 5.4%; p = .992), and minute ventilation (35.0 L/min and 35.0 L/min; p = .890) in control and obstructive sleep apnea patients, respectively. Both groups experienced similar percent increases in end-tidal CO2 (4.0% vs. 2.2%; p = .512) in control and obstructive sleep apnea patients, respectively. CONCLUSIONS: In pediatric surgical patients, obstructive sleep apnea status was not associated with significant differences in central respiratory depression following a single dose of fentanyl (1 mcg/kg). These findings can help determine safe opioid doses in future pediatric obstructive sleep apneapatients.

OBJECTIVE: To determine whether a postoperative prescription for opioids affects parental assessment of pain control following pediatric circumcision. METHODS: This postoperative survey assessed the parental assessment of pain control in 199 patients, ages<18 years undergoing circumcision. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 2018 to January 2020. Postoperative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for postoperative analgesia based on the surgical preference. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric circumcision as poor or inadequate based on the postoperative analgesic regimen. RESULTS: Of the 502 surveys sent, the response rate was 40% (199/502) of those who received the survey email, and 64% (199/308) for those who opened the email. Between the opioid and nonopioid groups, there was no difference in, race/ethnicity (Caucasian; 28% vs 37%; P = .43) or insurance status (insured; 51% vs 45%; P = .44). The proportion of parents who rated their child's pain as poor or inadequately controlled following circumcision was relatively rare:5.5% and 1.1% in the nonopioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following circumcision were 61% and 53% in the nonopioids and opioid groups, respectively. CONCLUSION: The results of this study indicate that nonopioid analgesic regimens following pediatric circumcision were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric circumcision is feasible and does not result in worse parental satisfaction with the analgesic plan.

BACKGROUND: Recently, there has been significant focus on the effects of anesthesia on the developing brain. Concern is heightened in children <3 years of age requiring lengthy and/or multiple anesthetics. Hypospadias correction is common in otherwise healthy children and may require both lengthy and repeated anesthetics. At academic centers, many of these cases are performed with the assistance of anesthesia and surgical trainees. We sought to identify both the incidence of these children undergoing additional anesthetics before age 3 as well as to understand the effect of trainees on duration of surgery and anesthesia and thus anesthetic exposure (AE), specifically focusing on those cases >3 hours. METHODS: We analyzed all cases of hypospadias repair from December 2011 through December 2018 at Texas Children's Hospital. In all, 1326 patients undergoing isolated hypospadias repair were analyzed for anesthesia time, surgical time, provider types involved, AE, caudal block, and additional AE related/unrelated to hypospadias. RESULTS: For the primary aim, a total of 1573 anesthetics were performed in children <3 years of age, including 1241 hypospadias repairs of which 1104 (89%) were completed with <3 hours of AE. For patients with <3 hours of AE, 86.1% had a single surgical intervention for hypospadias. Of patients <3 years of age, 17.3% required additional nonrelated surgeries. There was no difference in anesthesia time in cases performed solely by anesthesia attendings versus those performed with trainees/assistance (16.8 vs 16.8 minutes; P = .98). With regard to surgery, cases performed with surgical trainees were of longer duration than those performed solely by surgical attendings (83.5 vs 98.3 minutes; P < .001). Performance of surgery solely by attending surgeon resulted in a reduced total AE in minimal alveolar concentration (MAC) hours when compared to procedures done with trainees (1.92 vs 2.18; P < .001). Finally, comparison of patients undergoing initial correction of hypospadias with subsequent revisions revealed a longer time (117.7 vs 132.2 minutes; P < .001) and AE during the primary stage. CONCLUSIONS: The majority of children with hypospadias were repaired within a single AE. In general, most children did not require repeated AE before age 3. While presence of nonattending surgeons was associated with an increase in AE, this might at least partially be due to differences in case complexity. Moreover, the increase is likely not clinically significant. While it is critical to maintain a training environment, attempts to minimize AE are crucial. This information facilitates parental consent, particularly with regard to anesthesia duration and the need for additional anesthetics in hypospadias and nonhypospadias surgeries.

INTRODUCTION: Postoperative prescribing of opioids following pediatric adenotonsillectomy can have negative consequences including unnecessary opioid exposure and potential for respiratory depression. While guidelines from The American Academy of Otolaryngology/Head & Neck Surgery recommend treatment of post adenotonsillectomy pain using acetaminophen and ibuprofen, many providers continue to prescribe opioids and may do so, in part with concern for parental dissatisfaction with post-operative analgesia. Our aim was to determine whether a post-operative prescription for opioids affects parental assessment of pain control following pediatric adenotonsillectomy. METHODS: This post-operative survey assessed the parental assessment of pain control in 324 patients, ages 1-17 years undergoing adenotonsillectomy. This study was conducted at a quaternary care children's hospital in Houston, Texas from December 1, 2018 through March 31, 2019. Post-operative pain regimens included acetaminophen and ibuprofen or combination hydrocodone/acetaminophen in addition to ibuprofen for post-operative analgesia based on the attending surgeons prescribing preferences. The primary study outcome was identification of the proportion of parents rating their child's analgesia following pediatric adenotonsillectomy as poor or inadequate based on the post-operative analgesic regimen including opioids. RESULTS: Of the 798 surveys sent, the response rate was 42% (324/775) of those who received the survey email, and 69% (324/470) for those who opened the email. Between the opioid and non-opioid groups, there was no difference in gender (male; 48% vs. 51.3%; p = 0.58), race/ethnicity (white; 53% vs. 46%; p = 0.35) or insurance status (insured; 62% vs. 50.9%; p = 0.06). The proportion of parents who rated their child's pain as poor or inadequately controlled following adenotonsillectomy was relatively rare: 9% and 5% in the non-opioid and opioid groups, respectively. Parents rating their child's pain as excellent with regards to pain control following adenotonsillectomy were 58% and 50% in the non-opioids and opioid groups respectively. CONCLUSION: The results of this study indicate that non-opioid analgesic regimens following pediatric adenotonsillectomy were not associated with decreased parental satisfaction or an increasing assessment of poor or inadequately controlled pain. Limiting opioid exposure following pediatric adenotonsillectomy is feasible and does not result in worse parental satisfaction with the analgesic plan.

With a difficult National Institutes of Health (NIH) funding climate, the pipeline of physician-scientists in Anesthesiology is continuing to get smaller with fewer new entrants. This article studies current NIH funding trends and offers potential solutions to continue the historical trend of academic innovation and research that has characterized academic Anesthesiology. Using publicly available data, specifically the NIH REPORTeR and Blue Ridge Institute for Medical Research, we examined NIH trends in funding in academic Anesthesiology departments that have Anesthesiology residency training programs. When adjusted for inflation, median NIH funding of departments of Anesthesiology declined approximately 15% between 2008 and 2017. The majority (55%) of NIH funding to academic Anesthesiology departments, including R01 and K-series grants, went to 10 departments in the United States. This trend has remained relatively constant for the 9-year period we studied (2009-2017). There is an inequitable distribution of NIH funding to Anesthesiology departments. Arguably, this may be a case of the "rich get richer," but the implications for those who are trying to become or remain NIH-funded investigators are that success may depend, in part, on securing a faculty position in one of these well-funded departments.
