Single port robot-assisted pyeloplasty: An early comparative outcomes analysis.

BACKGROUND: The treatment paradigm for ureteropelvic junction obstruction (UPJO) has shifted towards minimally invasive pyeloplasty. A comparison Single Port (SP) and Multi Port (MP) robot-assisted pyeloplasty (RAP) was performed. METHODS: Data from consecutive patients undergoing SP RAP or MP RAP between January 2021 and September 2023 were collected and analysed. Co-primary outcomes were length of stay (LOS), Defense and Veterans Pain Rating Scale (DVPRS), and narcotic dose. The choice of the robotic system depended on the surgeon's preference and availability of a specific robotic platform. RESULTS: A total of 10 SP RAPs and 12 MP RAPs were identified. SP RAP patients were significantly younger [23 years (20-34)] than MP RAP [42 years (35.5-47.5), p < 0.01]. No difference in terms of OT (p = 0.6), LOS (p = 0.1), DVPRS (p = 0.2) and narcotic dose (p = 0.1) between the two groups was observed. CONCLUSIONS: SP RAP can be implemented without compromising surgical outcomes and potentially offering some clinical advantages.

Medical Economic Effect of Pharmaceutical Interventions by Board-Certified Pharmacists in Palliative Pharmacy for Patients with Cancer Using Medical Narcotics in Japan: A Multicenter, Retrospective Study.

BACKGROUND: The Japanese Society for Pharmaceutical Palliative Care and Sciences specializes in pharmacology in the field of palliative medicine. More than 700 board-certified pharmacists in palliative pharmacy (BCPPP) are actively involved in palliative pharmacotherapy at various hospitals and pharmacies. The purpose of this study was to determine the economic effect of pharmaceutical interventions by BCPPPs. METHODS: This multicenter retrospective study included 27 medical centers and analyzed the medical economic effect of interventions by BCPPPs (17 pharmacists) and non-BCPPPs (24 pharmacists) on patients using medical narcotics for cancer pain in September 2021. RESULTS: The percentage of patients who received a pharmaceutical intervention and whose drug costs were reduced by pharmacist intervention was significantly higher in the BCPPP group than in the non-BCPPP group. Although there was no significant difference between the two groups in drug cost reduction per patient per month (BCPPP group: $0.89 [-$64.91 to $106.76] vs. non-BCPPP group $0.00 [-$1,828.95 to $25.82]; P = 0.730), the medical economic benefit of pharmacist intervention in avoiding or reducing adverse drug reactions was higher in the BCPPP group ($103.18 [$0.00 to $628.03]) than in the non-BCPPP group ($0.00 [$0.00 to $628.03]) (P = 0.070). The total medical economic benefit-the sum of these-was significantly higher in the BCPPP group ($88.82 [-$14.62 to $705.37]) than in the non-BCPPP group ($0.66 [-$1,200.93 to $269.61]) (P = 0.006). CONCLUSION: Pharmacological intervention for patients with cancer using medical narcotics may have a greater medical economic benefit when managed by BCPPPs than by non-certified pharmacists in Japan.

Use of lateral femoral cutaneous nerve blocks by landmark technique is ineffective in decreasing narcotic usage after skin grafts: A retrospective case-control study.

INTRODUCTION: Cutaneous burns are commonly treated with autologous skin grafts. Following skin grafting, many patients complain of pain at the donor site. Donor sites are taken most commonly from the lateral thigh, which is innervated by the lateral femoral cutaneous nerve (LFCN). Use of a LFCN blocks should decrease nociception from the donor site. METHODS: Our group began utilizing LFCN blocks in 2019. Utilizing anatomic landmarks, LFCN blocks were performed on all patients who received autologous skin grafts to reduce perioperative pain. A retrospective cohort study was performed on all patients with 10% or less total body surface areas burns who received an autologous skin graft. A similar cohort from 2016, prior to use of any local or regional analgesia, was used as a historical control. Post-operative enteral and parenteral narcotic analgesics were collected for each post-operative day up to day 5 or discharge (whichever came first) and converted to morphine milligram equivalents (MME) to quantify analgesia after surgery. RESULTS: Chart review identified 55 patients in the 2020 cohort. Fifty-five patients from the 2016 cohort were matched based upon size of skin graft, total body surface area (TBSA) burned, gender, and age. There were no statistically significant differences between the two groups in terms of size of graft, TBSA burned, age, gender, or type of burn. When examining narcotics usage in the immediate perioperative period (days 0-2), we found no difference between the two groups for total MME (113 vs 133, p = 0.28) or IV MME (38 vs 33, p = 0.45). Similar relationships existed in the extended post-operative period (days 1-5) for total MME (149 vs. 188, t = 0.22) or IV MME (37 vs. 50, t = 0.25). Examining daily narcotic usage also yielded no statistically different values. CONCLUSION: Our data shows that use of LFCN block by landmark technique did not reduce narcotic usage in patients that undergo skin grafting procedures. Future studies should consider ultrasound-guided LFCN blocks.

Robotic versus open radical cystectomy for bladder cancer: evaluation of complications, survival, and opioid prescribing patterns.

We aim to compare complications, readmission, survival, and prescribing patterns of opioids for post-operative pain management for Robotic-assisted laparoscopic radical cystectomy (RARC) as compared to open radical cystectomy (ORC). Patients that underwent RARC or ORC for bladder cancer at a tertiary care center from 2005 to 2021 were included. Recurrence-free survival (RFS) and overall survival (OS) were evaluated with Kaplan-Meier curves and multivariable Cox proportional hazards regression models. Comparisons of narcotic usage were completed with oral morphine equivalents (OMEQ). Multivariable linear regression was used to assess predictors of OMEQ utilization. A total of 128 RARC and 461 ORC patients were included. There was no difference in rates of Clavien-Dindo grade ≥ 3 complications between RARC and ORC (36.7 vs 30.1%, p = 0.16). After a mean follow up of 3.4 years, RFS (HR 0.96, 95%CI 0.58-1.56) and OS (HR 0.69, 95%CI 0.46-1.05) were comparable between RARC and ORC. There was no difference in the narcotic usage between patients in the RARC and ORC groups during the last 24 h of hospitalization (median OMEQ: 0 vs 0, p = 0.33) and upon discharge (median OMEQ: 178 vs 210, p = 0.36). Predictors of higher OMEQ discharge prescriptions included younger age [(- )3.46, 95%CI (-)5.5-(-)0.34], no epidural during hospitalization [- 95.85, 95%CI (- )144.95-(- )107.36], and early time-period of surgery [(- )151.04, 95%CI (- )194.72-(- )107.36]. RARC has comparable 90-day complication rates and early survival outcomes to ORC and remains a viable option for bladder cancer. RARC results in comparable levels of opioid utilization for pain management as ORC.

Adductor Canal Nerve Block versus Intra-articular Anesthetic in Knee Arthroscopy: A Single-Blinded Prospective Randomized Trial.

Effective perioperative pain control following knee arthroscopy allows patients to reduce narcotic intake, avoid side effects of these medications, and recover more quickly. Adductor canal nerve blockade (ACB) and intra-articular injection of local anesthetic have been described as adjuvant treatments for postoperative pain control following surgery of the knee. This study directly compares the effect of each of these treatment modalities. Patients undergoing knee arthroscopy were blinded and randomized to receive either an ACB (n = 60) or intra-articular injection of local anesthetic (IAB, n = 64). Outcome measures included patient reported visual analog scale (VAS) scores at 1, 2, 4, 8, 16, 24, 36, 48 hours and 1 week and total narcotic consumption at 12, 24, and 48 hours postoperatively. Student's t-tests were used to compare unadjusted VAS scores at each time point and use of postoperative pain medication between treatment groups. Adjusted VAS scores were estimated in a multivariable general linear model with interaction of time and treatment group and other relevant covariates. There were no statistically significant differences between the two groups in terms of gender, age, body mass index, and insurance type. ACB patients had significantly higher pain scores than IAB patients at hours 1 and 2 (hour 1: 4.02 [2.99] vs. 2.59 [3.00], p = 0.009; hour 2: 3.12 [2.44] vs. 2.17 [2.62], p = 0.040). ACB patients had higher pain scores than IAB patients up to hour 16, though hours 4 to 16 were not significantly different. Adjusted covariate analyses demonstrate an additional statistically significant reduction in pain score in the IAB group at hour 4. There were no differences in narcotic consumption. Intraoperative local anesthetic and regional ACB each provides adequate pain control following knee arthroscopy, and intraoperative local anesthetic may provide enhanced pain control for up to 4 hours postoperatively. LEVEL OF EVIDENCE: : Level 1 evidence, randomized control trial.

Narcotic analgesics.

There is documentation of the use of opium derived products in the ancient history of the Assyrians: the Egyptians; in the sixth century AD by the Roman Dioscorides; and by Avicenna (980-1037). Reference to opium like products is made by Paracelsus and by Shakespeare. Charles Louis Derosne and Fredrich Wilhelm Adam Serturner isolated morphine from raw opium in 1802 and 1806 respectively, and it was Sertürner who named the substance morphine, after Morpheus, the Greek God of dreams. By the middle 1800s, Opium and related opioid derived products were the source of a major addiction in USA, and to some extent in the United Kingdom. Opioid products are of major therapeutic value in the treatment of pain from injury, post surgery, intractable pain conditions, and some forms of terminal cancer.

Randomized Controlled Trial Comparing Liposomal to Plain Bupivacaine in the Transversus Abdominis Plane for DIEP Flap Breast Reconstruction.

BACKGROUND: Pain control after autologous breast reconstruction is important for patient satisfaction and early recovery. Transversus abdominis plane (TAP) blocks are commonly used as part of an enhanced recovery after surgery (ERAS) pathway for breast reconstruction. It is uncertain whether liposomal bupivacaine used in TAP blocks offers additional advantages. This study aimed to compare the efficacy of liposomal bupivacaine versus plain bupivacaine for patients undergoing deep inferior epigastric perforator flap reconstruction. METHODS: This double-blinded randomized controlled trial studied patients undergoing abdominally based autologous breast reconstruction between June of 2019 and August of 2020. Subjects were randomly assigned liposomal or plain bupivacaine, performed using ultrasound-guided TAP block technique. All patients were managed according to an ERAS protocol. Primary outcomes were postoperative narcotic analgesia required, measured in oral morphine equivalents from postoperative days 1 to 7. Secondary outcomes included numeric pain scale score on postoperative days 1 to 7, nonnarcotic pain medication use, time to first narcotic use, return of bowel function, and length of stay. RESULTS: Sixty patients were enrolled: 30 received liposomal bupivacaine and 30 received plain bupivacaine. There were no significant differences in demographics, daily oral morphine equivalent narcotic use, nonnarcotic pain medication use, time to narcotic use, numeric pain scale score, time to bowel function, or length of stay. CONCLUSION: Liposomal bupivacaine does not confer advantages over plain bupivacaine when used in TAP blocks for abdominally based microvascular breast reconstruction in patients under ERAS protocols and multimodal approaches for pain control. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.

The Surgical Learning Curve for Cervical Disk Replacement.

STUDY DESIGN: Retrospective study. OBJECTIVE: To characterize an experienced single surgeon learning curve for cervical disk replacement (CDR). SUMMARY OF BACKGROUND DATA: A single surgeon learning curve has not been established for CDR. METHODS: Patients undergoing CDR were included. The cumulative sum of operative time was utilized to separate cases into 3 phases: learning, practicing, and mastery. Demographics, perioperative characteristics, complications, patient-reported outcomes (PROs), and radiographic outcomes were collected preoperatively and up to 1 year postoperatively. PROs included Patient-reported Outcomes Measurement Information System Physical Function, 12-item Short Form-12 Physical Component Score, 12-item Short Form-12 Mental Component Score, visual analog scale (VAS) arm, VAS neck, Neck Disability Index. Radiographic outcomes included segmental angle/segmental range of motion/C2-C7 range of motion. Minimum clinically important difference achievement was determined through a comparison of previously established values. RESULTS: A total of 173 patients were identified, with 14 patients in the learning phase, 42 patients in the practicing phase, and 117 patients in the mastery phase. Mean operative time and mean postoperative day 0 narcotic consumption were significantly higher in the learning phase. The preoperative segmental angle was significantly lower for the learning phase, though these differences were eliminated at the final postoperative time point. Patients in the learning phase reported worse improvement to 6-week postoperative, final postoperative, and worse overall final postoperative VAS Arm scores compared with practicing and mastery phases. CONCLUSIONS: For an experienced spine surgeon, the learning phase for CDR was estimated to span 14 patients. During this phase, patients demonstrated longer operative times, higher postoperative narcotic consumption, and worse postoperative VAS Arm scores. Radiographically, no postoperative differences were noted between different phases of mastery. This single surgeon learning curve demonstrates that CDR may be performed safely and with comparable outcomes by experienced spine surgeons despite decreased operative efficiency in the learning phase.

Trends in Management of Anal Fissures.

BACKGROUND: It is unclear how patients with anal fissures are treated in real-world settings, particularly since patients may not see colorectal surgeons. This study describes trends in treatment with medical therapies (calcium-channel blockers [CCBs], nitroglycerin [NTG], and narcotics) and surgical treatments. METHODS: Cohorts were created within the TriNetX database platform using codes for anal fissures and surgical interventions. Demographics were compared between patients that received surgical intervention within 1 year of diagnosis, CCB or NTG within 1 year (or preoperatively), or narcotics within 30 days or postoperatively vs those who did not. RESULTS: 121,213 patients were included of which 4.0% had surgical intervention. Factors associated with surgical intervention were male sex (OR 1.40), White race (OR 1.17), and Hispanic ethnicity (OR 1.11). Male patients were more likely to undergo sphincterotomy (OR 1.49). Female (OR 1.27), non-Hispanic (OR 1.34), and White patients (OR 1.41) were more likely to have chemodenervation. Regarding nonoperatively managed patients, non-Hispanic (OR .91) and White patients (OR .89) were less likely to receive CCB/NTG. Male (OR 1.21), non-Hispanic (OR 1.08), and Black patients (OR 1.20) were more likely to receive narcotics. Male patients that required surgery were more likely to be prescribed CCB/NTG preoperatively (OR 1.27). Non-Hispanic surgical patients were more likely to receive narcotics (OR 1.84). DISCUSSION: Male fissure patients were more likely to undergo surgical intervention other than chemodenervation. Differences in the rates of surgery and medical therapy (especially narcotics) between races and ethnicities require exploration to enhance the care of patients with anal fissures.

Randomized Trial on Expectations and Pain Control Advancement in Surgery: The REPAIR Study.

IMPORTANCE: Following standardized preoperative education and adoption of shared decision making positively affects postoperative narcotic practices. OBJECTIVES: The aim of this study was to assess the impact of patient-centered preoperative education and shared decision making on the quantities of postoperative narcotics prescribed and consumed after urogynecologic surgery. STUDY DESIGN: Women undergoing urogynecologic surgery were randomized to "standard" (standard preoperative education, standard narcotic quantities at discharge) or "patient-centered" (patient-informed preoperative education, choice of narcotic quantities at discharge) groups. At discharge, the "standard" group received 30 (major surgery) or 12 (minor surgery) pills of 5-mg oxycodone. The "patient-centered" group chose 0 to 30 (major surgery) or 0 to 12 (minor surgery) pills. Outcomes included postoperative narcotics consumed and unused. Other outcomes included patient satisfaction/preparedness, return to activity, and pain interference. An intention-to-treat analysis was performed. RESULTS: The study enrolled 174 women; 154 were randomized and completed the major outcomes of interest (78 in the standard group, 76 in the patient-centered group). Narcotic consumption did not differ between groups (standard group: median of 3.5 pills, interquartile range [IQR] of [0, 8.25]; patient centered: median of 2, IQR of [0, 9.75]; P = 0.627). The patient-centered group had fewer narcotics prescribed ( P < 0.001) and unused ( P < 0.001), and chose a median of 20 pills (IQR [10, 30]) after a major surgical procedure and 12 pills (IQR [6, 12]) after a minor surgical procedure, with fewer unused narcotics (median difference, 9 pills; 95% confidence interval, 5-13; P < 0.001). There were no differences between groups' return to function, pain interference, and preparedness or satisfaction ( P > 0.05). CONCLUSIONS: Patient-centered education did not decrease narcotic consumption. Shared decision making did decrease prescribed and unused narcotics. Shared decision making in narcotic prescribing is feasible and may improve postoperative prescribing practices.

Opioid Use, Disposition, and Parent Satisfaction Following Common Pediatric Surgical Procedures.

INTRODUCTION: There is wide variability in prescribing practices among providers, even for patients undergoing the same operations. Our study aims to analyze the variation in opioid prescription practices using a patient-centered approach to establish more appropriate prescribing guidelines for health care providers. METHODS: We conducted phone surveys 30 days after surgery to assess patient-reported opioid use. Over a two-year collection period, we identified patients that had undergone common outpatient pediatric surgery procedures in our 4-surgeon group. Included in the survey tool was the narcotic prescribed (if any), the amount used, and patient/family rating of pain control. RESULTS: We collected data for 189 separate procedures (88 umbilical hernias, 30 laparoscopic inguinal hernias, 2 open inguinal hernias, 41 appendectomies, 15 laparoscopic cholecystectomies, and 13 pectus bar removals). Patient age ranged from less than 1 month to 246 months. 83.5% of patients had a narcotic prescribed. The average number of doses used was 4, ranging from 0 (11.3%) to 30 (1.5%). 72.6% of families surveyed felt pain control was appropriate. However, 19.6% did feel they received too much pain medication. 10.6% reported completing their entire prescription; however, only 13.6% of families with excess narcotics reported proper disposal. CONCLUSIONS: Despite heightened awareness of the opioid epidemic, there is still a poor understanding of appropriate pain control regimens in the pediatric surgical population. We demonstrate that most patients are discharged home with excess opioids and that many families save the leftover pills/liquid. Further research and education are encouraged to limit the use of opioids in standard pediatric surgical procedures.

The I-STOP Program and Narcotic Prescriptions Following Facial Reconstructive Plastic Surgeries.

OBJECTIVES: To explore the effect of e-prescribing requirements on narcotic dispersion in New York State. Slicer Dicer was used to identify patient records based on CPT codes. METHODS: We investigated the influence of New York State e-prescribing requirements on narcotic dispersion following five common facial plastics procedures. Slicer Dicer was used to identify patient records based on CPT codes.We then looked at narcotic prescription rates following those surgeries between March 2014 and March 2018 at an academic institution. RESULTS: Overall, between March 2014 and March 2018, 76.1% of the sample received a narcotic prescription following a facial reconstructive plastic surgery. Patients who underwent rhinoplasty were most likely to receive a prescription for postoperative narcotics. The implementation of ISTOP, CPT code, use of non-narcotic adjuvant, and insurance type were each significantly associated with prescription of postoperative narcotics. Surgery time and age in years were significantly associated with prescription of postoperative narcotics. Ultimately, when controlling for the aforementioned clinical and sociodemographic variables included in the study, those who underwent surgery after the implementation of ISTOP were 42.8% less likely to receive a prescription for postoperative narcotics, aOR = 0.572, 95% CI 0.356, 0.919, p = 0.021. CONCLUSIONS: New York State's ISTOP program has succeeded in reducing the number of postoperative narcotic prescriptions following facial plastic reconstructive surgeries at this academic institution. However, opioid medications can still be utilized for postoperative analgesia when clinically appropriate. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1208-1213, 2024.

Persistent long-term opioid use after trauma: Incidence and risk factors.

BACKGROUND: The opioid epidemic in the United States continues to lead to a substantial number of preventable deaths and disability. The development of opioid dependence has been strongly linked to previous opioid exposure. Trauma patients are at particular risk since opioids are frequently required to control pain after injury. The purpose to this study was to examine the prevalence of opioid use before and after injury and to identify risk factors for persistent long-term opioid use after trauma. METHODS: Records for all patients admitted to a Level 1 trauma center over a 1-year period were analyzed. Demographics, injury characteristics, and hospital course were recorded. A multistate Prescription Drug Monitoring Program database was queried to obtain records of all controlled substances prescribed from 6 months before the date of injury to 12 months after hospital discharge. Patients still receiving narcotics at 1 year were defined as persistent long-term users and were compared against those who were not. RESULTS: A total of 2,992 patients were analyzed. Of all patients, 20.4% had filled a narcotic prescription within the 6 months before injury, 53.5% received opioids at hospital discharge, and 12.5% had persistent long-term use after trauma with the majority demonstrating preinjury use. Univariate risk factors for long-term use included female sex, longer length of stay, higher Injury Severity Score, anxiety, depression, orthopedic surgeries, spine injuries, multiple surgical locations, discharge to acute inpatient rehab, and preinjury opioid use. On multivariate analysis, the only significant predictors of persistent long-term prescription opioid use were preinjury use and a much smaller effect associated with use at discharge. CONCLUSION: During a sustained opioid epidemic, concerns and caution are warranted in the use of prescription narcotics for trauma patients. However, persistent long-term opioid use among opioid-naive patients is rare and difficult to predict after trauma. LEVEL OF EVIDENCE: Prognostic and Epidemiological; Level III.

Does Anesthesiologist Experience Influence Early Postoperative Outcomes Following Orthognathic Surgery?

BACKGROUND: Anesthesia provider experience impacts nausea and vomiting in other surgical specialties but its influence within orthognathic surgery remains unclear. PURPOSE: The study purpose was to evaluate whether anesthesiologist experience with orthognathic surgery impacts postoperative outcomes, including nausea, emesis, narcotic use, and perioperative adverse events, for patients undergoing orthognathic surgery. STUDY DESIGN, SETTING, SAMPLE: This is a retrospective cohort study of subjects aged 12 to 35 years old who underwent orthognathic surgery, including Le Fort 1 osteotomy ± bilateral sagittal split osteotomy, at Boston Children's Hospital from August 2018 to January 2022. Subjects were excluded if they had incomplete medical records, a syndromic diagnosis, or a hospital stay of greater than 2 days. PREDICTOR VARIABLE: The predictor variable was attending anesthesia provider experience with orthognathic surgery. Providers were classified as experienced or inexperienced, with experienced providers defined as having anesthetized ≥10 orthognathic operations during the study period. MAIN OUTCOME VARIABLES: The primary outcome variable was postoperative nausea. Secondary outcome variables were emesis, narcotic use in the hospital, and perioperative adverse events within 30 days of their operation. COVARIATES: Study covariates included age, sex, race, comorbidities (body mass index, history of psychiatric illness, cleft lip and/or palate, chronic pain, postoperative nausea/vomiting, gastrointestinal conditions), enhanced recovery after surgery protocol enrollment, and intraoperative factors (operation performed, anesthesia/procedure times, estimated blood loss, intravenous fluid and narcotic administration, and anesthesiologist's years in practice). ANALYSES: χ2 and unpaired t-tests were used to compare primary predictor and covariates against outcome variables. A P-value <.05 was considered significant. RESULTS: There were 118 subjects included in the study after 4 were excluded (51.7% female, mean age 19.1 ± 3.30 years). There were 71 operations performed by 5 experienced anesthesiologists (mean cases/provider 15.4 ± 5.95) and 47 cases by 22 different inexperienced providers (mean cases/provider 1.91 ± 1.16). The nausea rate was 52.1% for experienced providers and 53.2% for inexperienced providers (P = .909). There were no statistically significant associations between anesthesiologist experience and any outcome variable (P > .341). CONCLUSIONS AND RELEVANCE: Anesthesia providers' experience with orthognathic surgery did not significantly influence postoperative nausea, emesis, narcotic use, or perioperative adverse events.

Anterior Cervical Discectomy and Fusion Versus Cervical Disc Replacement for a Workers' Compensation Population in an Ambulatory Surgical Center.

STUDY DESIGN: Retrospective Cohort. OBJECTIVE: To evaluate patient-reported outcome measures (PROM) and minimal clinically important difference (MCID) achievement outcomes between anterior cervical discectomy and fusion (ACDF) and cervical disk replacement (CDR) in the Workers' Compensation (WC) population. SUMMARY OF BACKGROUND DATA: No studies to our knowledge have compared PROMs and MCID attainment between ACDF and CDR among patients with WC insurance undergoing surgery in an outpatient ambulatory surgical center (ASC). METHODS: WC insurance patients undergoing primary, single/double-level ACDF/CDR in an ASC were identified. Patients were divided into ACDF versus CDR. PROMs were collected at preoperative/6-week/12-week/6-month/1-year timepoints, including PROMIS-PF, SF-12 PCS/MCS, VAS neck/arm, and NDI. RESULTS: Seventy-nine patients were included, 51 ACDF/28 CDR. While operative time (56.4 vs. 54.4 min), estimated blood loss (29.2 vs. 25.9 mL), POD0 pain (4.9 vs. 3.8), and POD0 narcotic consumption (21.2 vs. 14.5 oral morphine equivalents) were higher in ACDF patients, none reached statistical significance ( P >0.050, all). One-year arthrodesis rate was 100.0% among ACDF recipients with available imaging (n=36). ACDF cohort improved from preoperative for PROMIS-PF from 12 weeks to 1 year, SF-12 PCS at 6 months, all timepoints for VAS neck/arm, and 12 weeks/6 months for NDI ( P ≤0.044, all). CDR cohort improved from preoperative for PROMIS-PF at 6 months, VAS neck/arm from 12 weeks to 1 year, and NDI at 12 weeks/6 months ( P ≤0.049, all). CDR cohort reported significantly lower VAS neck at 12 weeks/1 year and VAS arm at 12 weeks ( P ≤0.039, all). MCID achievement rates did not differ. CONCLUSION: While operative duration/estimated blood loss/acute postoperative pain/narcotic consumption were, on average, higher among ACDF recipients, these were not statistically significant, possibly due to the limited sample size. ACDF and CDR ASC patients generally demonstrated comparable arm pain/disability/physical function/mental health, though neck pain was significantly lower at multiple timepoints among CDR patients. Clinically meaningful PROM improvements were comparable. Larger, multicentered studies are required to confirm our results.

Effects of inhaled low-concentration xenon gas on naltrexone-precipitated withdrawal symptoms in morphine-dependent mice.

BACKGROUND: Opioid withdrawal symptoms (OWS) are highly aversive and prompt unprescribed opioid use, which increases morbidity, mortality, and, among individuals being treated for opioid use disorder (OUD), recurrence. OWS are driven by sympathetic nervous system (SNS) hyperactivity that occurs when blood opioid levels wane. We tested whether brief inhalation of xenon gas, which inhibits SNS activity and is used clinically for anesthesia and diagnostic imaging, attenuates naltrexone-precipitated withdrawal-like signs in morphine-dependent mice. METHODS: Adult CD-1 mice were implanted with morphine sulfate-loaded (60 mg/ml) minipumps and maintained for 6 days to establish morphine dependence. On day 7, mice were given subcutaneous naltrexone (0.3 mg/kg) and placed in a sealed exposure chamber containing either 21% oxygen/balance nitrogen (controls) or 21% oxygen/added xenon peaking at 30%/balance nitrogen. After 10 minutes, mice were transferred to observation chambers and videorecorded for 45 minutes. Videos were scored in a blind manner for morphine withdrawal behaviors. Data were analyzed using 2-way ANOVAs testing for treatment and sex effects. RESULTS AND CONCLUSIONS: Xenon-exposed mice exhibited fewer jumps (P = 0.010) and jumping suppression was detectible within the first 10-minute video segment, but no sex differences were detected. Brief inhalation of low concentration xenon rapidly and substantially attenuated naltrexone-precipitated jumping in morphine-dependent mice, suggesting that it can inhibit OWS. If xenon effects translate to humans with OUD, xenon inhalation may be effective for reducing OWS, unprescribed opioid use, and for easing OUD treatment initiation, which could help lower excess morbidity and mortality associated with OUD.

Erector Spinae versus Surgically Placed Pain Catheters for Thoracic Outlet Decompression.

BACKGROUND: Perioperative care after surgery for thoracic outlet syndrome (TOS) involves multimodal pain control. Pain catheters with bupivacaine infusion are a modality to minimize perioperative narcotic use. Our study aims to compare surgically placed pain catheters (SP) with erector spinae pain catheters (ESP) placed by the anesthesia pain service. METHODS: Retrospective review of a prospectively maintained surgical TOS database identified patients undergoing transaxillary first rib resection (FRR) who had either SP or ESP placed for pain control. Patients were matched for age and gender. Data collected included demographics, operative details, and perioperative pain medication use. Narcotic pain medication doses were converted to milligram morphine equivalents (MMEs) for comparison between groups. Pain medications were collected for several time points: intraoperatively, for each postoperative day (POD) and for the entire hospital stay. RESULTS: Eighty-eight total patients were selected for comparison: 44 patients in the SP and ESP groups. Patients in each group did not differ with regards to age, body mass index, gender, diagnosis, or comorbidities. There were no differences in preoperative narcotic use, preoperative pain score, or Quick Disabilities of Arm, Shoulder, and Hand score. All patients underwent FRR. Concurrent cervical rib resection was performed in 6.8% SP and 6.8% ESP patients (P = 1.00), pectoralis minor tenotomy in 34.1% SP and 29.5% ESP patients (P = 0.65), and venogram in 31.8% SP and 31.8% ESP patients (P = 1.00). Mean operating room time was 90.0 min in SP and 105.3 min in ESP cases (P = 0.15). Mean length of stay was 1.9 days for SP and 1.8 days for ESP patients (P = 0.56). There were no significant differences in intraoperative narcotics dosing in MME (SP: 22.1 versus ESP: 25.3, P = 0.018). On POD 0, there were no differences in total narcotics dosing (MME) (SP: 112.0 versus ESP: 100.7, P = 0.59), or in the use of acetaminophen, nonsteroidal anti-inflammatory drugs, or muscle relaxants. A similar trend in narcotics dosing was observed on POD 1 (SP: 58.6 versus ESP: 69.7, P = 0.43) and POD 2 (SP: 23.5 versus ESP: 71.3, P = 0.23). On POD 1, there was a higher percentage of SP patients taking nonsteroidal anti-inflammatory drugs (63.6% vs. 40.9%, P = 0.024); however, this difference was not observed on POD 2. There were no differences in acetaminophen or muscle relaxant use on POD 1 or 2. Total hospital stay MME was similar between groups (SP: 215.9 versus ESP: 250.9, P = 0.23). CONCLUSIONS: Pain catheters with bupivacaine infusions are helpful adjuncts in postoperative pain control after FRR for TOS. This study compares SP to ESP and demonstrates no difference in narcotics use between SP and ESP groups. SP should be used for pain control in facilities which do not have an anesthesia pain service available for ESP placement.

[Male infertility, environment and lifestyle]. / Infertilité masculine, environnement et mode de vie.

BACKGROUND: Since the 1970s, there has been a quantitative and qualitative decline in sperm parameters. The main hypothesis to explain such a rapid evolution is the involvement of environmental and behavioral phenomena. METHODS: A bibliographic search limited to English and French literature in men published before 7/2023 was carried out on the links between fertility and pollution, xenobiotics, tobacco, narcotics, cannabis, alcohol, weight, sport, sedentary lifestyle, sleep and anabolics. RESULTS: Profound changes in lifestyle have occurred over the past 50 years: reduced sleep time, sedentary lifestyle, dietary changes, tobacco consumption, use of narcotics and anabolics. These changes have a proven impact on spermogram parameters, and should be corrected in an effort to optimize reproductive health. Other environmental parameters: pollution, exposure to heavy metals, exposure to xenobiotics, phthalates and pesticides… will be more difficult to exclude from patients' daily lives, but deserve to be taken more into account. CONCLUSION: This review should help the urologist to assess and counsel patients in order to improve their reproductive health. These factors should be routinely investigated in infertile men.

Detroit Interventional Pain Assessment Scale: A Pain Score and Method for Measuring and Evaluating Post-Operative Pain Management-A Prospective Study.

Background and Objectives: Orthopedic surgeons commonly prescribe opioids, surpassing all medical specialties. Our objective was to develop a pain management scale that captures medication use, patient-reported pain scores, and helps orthopedic surgeons evaluate their post-operative prescribing practice. Materials and Methods: An IRB-approved prospective study followed 502 post-operative orthopedic surgery patients over a six-month period. All patients were surveyed in an orthopedic clinic at a Level 1 US Trauma Center, during a routine follow-up. Patient pain satisfaction was assessed using the validated Interventional Pain Assessment (IPA) scale, which uses three categories: 0 (no pain), 1 (tolerable pain), and 2 (intolerable pain). Daily narcotic use was translated to morphine milligram equivalents (MMEs) using the Michigan Automated Prescription System (MAPS) narcotics registry. When patient pain satisfaction and narcotic usage were combined, this scale was called the Detroit Interventional Pain Assessment (DIPA) scale. Results: The five classes based on common prescription and usage of narcotics in this cohort include the following: A (no pain medication), B (over-the-counter medication), C (occasional use of short-acting narcotics 1-30 MMEs), D (consistent/regular use of short-acting narcotics 31-79 MMEs), and E (long-duration or stronger short-acting narcotics 80+ MMEs). Patients were most satisfied with their pain management at six weeks (80.5%) and three months (75.65%), and least satisfied at two weeks (62.5%) and six months (60.9%). Additional information displayed on the DIPA graph revealed there was a significant decrease in the percentage of patients on narcotics at two weeks (65.2%) to six months (32.6%) at p < 0.001. Conclusions: The DIPA pain scale shows the relationship between patient pain perception and opioid prescription/usage, while also tracking prescriber tendencies. Providers were able to visualize their post-operative pain management progression at each designated clinic visit with corresponding alphabetical daily MME categories. In this study, results suggest that surgeons were not effective at managing the pain of patients at two weeks post-operative, which is attributed to an inadequate number of pain pills prescribed upon discharge. Overall, the DIPA graph signaled that better pain management interventions are necessitated in periods with lower efficiency scores.
