RESUMEN
BACKGROUND: Gabapentin, a widely prescribed medication for various neuropathic pain conditions, has demonstrated efficacy in managing diverse neurological disorders. While conventional side effects are well-documented, a growing body of evidence suggests the existence of atypical side effects, necessitating comprehensive exploration. This paper aims to systematically review and summarize the literature on the atypical side effects of gabapentin, shedding light on manifestations beyond the conventional spectrum. METHODS: A systematic review was conducted, encompassing peer-reviewed articles published up to the knowledge cutoff date in November 2023. Databases, specifically PubMed, were searched for relevant studies, focusing on atypical side effects such as myoclonus, ataxia, pediatric aggression, respiratory depression, pneumonia, pregnancy complications, sleep interference, encephalopathy, peripheral edema, suicidal ideation, dyskinesia, anorgasmia, and myopathy. Inclusion criteria comprised studies with a focus on gabapentin-related atypical side effects, published in recognized journals and involving human subjects. RESULTS: The review identified a spectrum of atypical side effects associated with gabapentin use, ranging from neurological manifestations like myoclonus and ataxia to behavioral changes such as pediatric aggression and suicidal ideation. Additionally, respiratory complications, pregnancy-related issues, sleep disturbances, and rare complications like encephalopathy and myopathy were observed. Literature synthesis provided insights into the incidence, clinical presentation, and potential mechanisms underlying these atypical side effects. CONCLUSION: This comprehensive review highlights the diverse range of atypical side effects associated with gabapentin use, expanding beyond conventional knowledge. Healthcare practitioners must be cognizant of these manifestations, recognizing their potential impact on patient well-being. As clinical decision-making relies on a thorough understanding of a medication's side effect profile, this review contributes to enhancing awareness and fostering informed practices in the prescription and management of gabapentin. Further research is warranted to elucidate the mechanisms and risk factors associated with these atypical side effects, refining our understanding of gabapentin's safety profile.
RESUMEN
Background and Aims: Opioid-sparing analgesia for acute postoperative pain after breast cancer surgery is crucial due to opioid-related side effects. The utilisation of erector spinae plane block and low-dose intravenous ketamine-dexmedetomidine are widely recognised as non-opioid analgesic methodologies. The objective of this study was to conduct a randomised trial to examine the analgesic efficacy of both approaches while minimising the use of opioids. Methods: Seventy-two female patients scheduled for unilateral modified radical mastectomy were recruited. They were allocated randomly to Group ESPB, which received ipsilateral ultrasound-guided erector spinae plane block by 20 mL bupivacaine 0.5% at the level of T5 after induction of general anaesthesia, and Group Ket-Dex, which received intravenous (IV) bolus 0.25 mg/kg of ketamine and 0.5 µg/kg of dexmedetomidine, followed by an IV infusion of 0.25 mg/kg of ketamine and 0.3 µg/kg of dexmedetomidine per hour. Total postoperative morphine consumption (24 h) was the primary outcome. The secondary outcomes were pain scores over 24 hours during rest, duration of analgesia, isoflurane consumption, time to awakening, postoperative nausea and vomiting (PONV), and postoperative serum cortisol level. Results: The postoperative morphine consumption over 24-hour in Group ESPB was 3.26 mg (0-6.74) versus 2.35 mg (2.08-4.88) in Group Ket-Dex (P = 0.046). Group Ket-Dex had lower pain scores at rest, longer analgesia duration, longer awakening time, and lower postoperative serum cortisol levels. Conclusion: Intravenous low-dose ketamine-dexmedetomidine infusion intraoperatively with inhalational-based general anaesthesia provides superior opioid-sparing analgesia to that of ESPB in patients undergoing unilateral non-reconstructive modified radical mastectomy, with less postoperative opioid consumption and stress response.
RESUMEN
BACKGROUND: Video-assisted thoracoscopic surgery (VATS) often induces significant postoperative pain, potentially leading to chronic pain and decreased quality of life. This study aimed to evaluate the acetaminophen/ibuprofen combination effectiveness in reducing analgesic requirements and pain intensity in patients undergoing VATS. STUDY DESIGN: This is a double-blinded randomized controlled trial. METHODS: Adult patients scheduled for elective VATS for lung resection were randomized to receive either intravenous acetaminophen and ibuprofen (intervention group) or 100 mL normal saline (control group). Treatments were administered post-anesthesia induction and every 6 h for three cycles. The primary outcome was total analgesic consumption at 24 h postoperatively. Secondary outcomes were cumulative analgesic consumption at 2 and 48 h; analgesic-related side effects at 2, 24, and 48 h; quality of recovery at 24 h and 48 h postoperatively; pain intensity at rest and during coughing; and rescue analgesics use. Chronic postsurgical pain (CPSP) was assessed through telephone interviews 3 months postoperatively. RESULTS: The study included 96 participants. The intervention group showed significantly lower analgesic consumption at 24 h and 48 h postoperatively (24 h: median difference: - 100 µg equivalent intravenous fentanyl [95% confidence interval (CI) - 200 to - 5 µg], P = 0.037; 48 h: median difference: - 140 µg [95% CI - 320 to - 20 µg], P = 0.035). Compared to the controls, the intervention group exhibited a significantly lower quality of recovery 24 h post-surgery, with no significant difference at 48 h. All pain scores except for coughing at 48 h post-surgery were significantly lower in the intervention group compared to the controls. No significant differences were observed between the groups in postoperative nausea and vomiting occurrence, hospital stay length, and CPSP. CONCLUSION: Perioperative administration of acetaminophen/ibuprofen significantly decreased analgesic needs in patients undergoing VATS, providing an effective postoperative pain management strategy, and potentially minimizing the need for stronger analgesics.

Odontogenic pain can be debilitating, and nonopioid analgesic options are limited. This randomized placebo-controlled clinical trial aimed to assess the effectiveness and safety of cannabidiol (CBD) as an analgesic for patients with emergency acute dental pain. Sixty-one patients with moderate to severe toothache were randomized into 3 groups: CBD10 (CBD 10 mg/kg), CBD20 (CBD 20 mg/kg), and placebo. We administered a single dose of respective oral solution and monitored the subjects for 3 h. The primary outcome measure was the numerical pain differences using a visual analog scale (VAS) from baseline within and among the groups. Secondary outcome measures included ordinal pain intensity differences, the onset of significant pain relief, maximum pain relief, changes in bite force within and among the groups, psychoactive effects, mood changes, and other adverse events. Both CBD groups resulted in significant VAS pain reduction compared to their baseline and the placebo group, with a maximum median VAS pain reduction of 73% from baseline pain at the 180-min time point (P < 0.05). CBD20 experienced a faster onset of significant pain relief than CBD10 (15 versus 30 min after drug administration), and both groups reached maximum pain relief at 180-min. Number needed to treat was 3.1 for CBD10 and 2.4 for CBD20. Intragroup comparisons showed a significant increase in bite forces in both CBD groups (P < 0.05) but not in the placebo group (P > 0.05). CBD20 resulted in a significant difference in mean percent bite force change in the 90- and 180-min time points compared to the placebo group (P < 0.05). Compared to placebo, sedation, diarrhea, and abdominal pain were significantly associated with the CBD groups (P < 0.05). There were no other significant psychoactive or mood change effects. This randomized trial provides the first clinical evidence that oral CBD can be an effective and safe analgesic for dental pain.

Photocatalytic degradation of pharmaceutical residues through natural solar radiation represents a green and economical treatment process. In this work, ultrasonically assisted hydrothermal synthesis of WO3-TiO2 nanocomposite was carried out at 140-150 °C for 5 h and calcinated at 600 °C. The structural and optical properties of the synthesized material were investigated using techniques like XRD, FESEM/EDX, HRTEM, BET surface area, UV-DRS optical analysis, and photocurrent response. The band gap of TiO2 was successfully reduced from 3.0 to 2.54 eV and thus making it effective under solar light. Complete degradation of paracetamol (50 ppm and natural pH of 6.5) was achieved in 3.5 h under natural sunlight at catalyst dose of 0.5 g/l. The extent of mineralization was evaluated by measuring the COD reduction. Based on the degradation products identified by GC-MS/LC-TOF-MS, the degradation process under natural solar-light could be interpreted to initiate through OH. radical species. The toxicity removal of the treated paracetamol solution under natural solar-light was evaluated by the seed germination test using Spinacia oleracea seeds and exhibited 66.70% seed germination, confirming the reduction in toxicity. The enhanced photocatalytic efficiency of the nanocomposite is attributed to the higher surface area, low rutile content, lower band gap, and incorporation of WO3, which led to an extended absorption range and a slower rate of electron-hole recombination. The technical insights presented in this research offer a feasible approach for utilizing natural solar light driven photocatalysis for wastewater treatment in an efficient and sustainable way. The proposed degradation pathway, and seed germination test (toxicity removal) of the treated paracetamol solution under natural sunlight, has not been previously evaluated.

BACKGROUND: Limited data exist concerning the management of postoperative pain after robotic-assisted surgery. The present study was performed to investigate the efficacy of intrathecal morphine and bupivacaine to treat postoperative pain in adult women undergoing robot-assisted laparoscopic hysterectomy. METHODS: The primary outcomes of this study were opioid consumption and pain scores during and after robotic surgery. 96 patients were prospectively enrolled and randomized to a nonspinal group (n = 48) and a spinal group (n = 48). The intrathecal regimen consisted of 100 µg morphine and 15 mg of bupivacaine. The numeric rating scale scores (NRS) were assessed every 15 min in the postoperative care unit (PACU) and pain was treated with iv fentanyl or morphine when NRS was above 5 and orally oxycodone when NRS was 3-5. Cumulative iv opioid-consumption and NRS scores were compared. RESULTS: Intrathecal morphine and bupivacaine resulted in a significantly lower cumulative total iv opioid (morphine equivalents) consumption (9.4 ± 3.9 vs. 22.8 ± 6.1 mg equivalents). Highest recorded NRS scores in the PACU were also significantly lower in the spinal group (2.0 ± 2.6 vs. 5.3 ± 3.2). CONCLUSION: Intrathecal morphine and bupivacaine to treat postoperative pain after robotic-assisted laparoscopic hysterectomy decrease total opioid consumption and NRS pain scores. This might be of great importance to diminish the rate of other serious disadvantages related to opioids.

Background: Opioids and derivatives of opium had been used as analgesics for thousands of years before the introduction of inhalational anesthetic agents. Once these early volatile agents were in widespread use, opioids were used as part of anesthetic care for premedication, as intraoperative adjuncts to general anesthesia, and for the management of postoperative pain. Evidence of growing dependence on opioids in the perioperative and periprocedural patient is supported by the ongoing research to develop synthetic opioids and to customize the pharmacokinetics and pharmacodynamics to achieve specific therapeutic goals. Methods: We explore the history of opioid use in perioperative care as a means of future management in light of new persistent opioid abuse. Results: As the opium chemical structure has been modified, newer nonopioid analgesics have been approved and brought into clinical practice. Opioid-sparing and opioid-free anesthetic techniques are not only a possibility, but a reality. Conclusion: Continuing research in neurobiology and addiction genetics will ultimately lead to a pharmacogenetic approach to patients at risk for new persistent opioid abuse.
RESUMEN
PURPOSE: The purpose of this study was to assess the performance of a reinforced analgesic protocol (RAP) on pain control in patients undergoing conventional trans-arterial chemoembolization (cTACE) for hepatocellular carcinoma (HCC). MATERIALS AND METHODS: Eighty-one consecutive patients (57 men, 24 women) with a mean age of 69 ± 10 (standard deviation) years (age range: 49-92 years) underwent 103 cTACEs. Standard antalgic protocol (50 mg hydroxyzine, 10 mg oxycodone, 8 mg ondansetron, and lidocaine for local anesthesia) was prospectively compared to a RAP (standard + 40 mg 2-h infusion nefopam and 50 mg tramadol). The individual pain risk was stratified based on age, the presence of cirrhosis and alcoholic liver disease, and patients were assigned to a low-risk group (standard protocol) or high-risk group (RAP). The primary endpoint was severe periprocedural abdominal pain (SAP), defined as a visual analog scale score ≥30/100. A predefined intermediate analysis was performed to monitor the benefit-risk of the RAP. Based on the intermediate analysis, all patients were treated with the RAP. RESULTS: The intermediate analysis performed after 52 cTACE showed that 2/17 (12%) high-risk patients (i.e., those receiving the RAP) experienced SAP compared to 15/35 (43%) low-risk patients (odds ratio [OR] = 0.18; 95% confidence interval [CI]: 0.02-0.98; P = 0.03). Analysis of all procedures showed that 12/67 (18%) patients in cTACE receiving the RAP experienced SAP compared to 15/36 (42%) patients who did not receive it (OR = 3.27; 95% CI: 1.32-8.14; P = 0.01). There were no statistical differences in adverse events, particularly for nausea, between groups. CONCLUSION: Reinforcing the analgesic protocol by combining non-opioid and opioid molecules reduces perioperative pain in patients undergoing cTACE for HCC.

INTRODUCTION: Opioid prescribing patterns after pediatric tonsillectomy are highly variable, and opioids may not improve pain control compared to over-the-counter pain relievers. We evaluated whether a standardized, opioid-sparing analgesic protocol effectively reduced opioid prescriptions without compromising patient outcomes. METHODS: A quality improvement project was initiated in July 2019 to standardize analgesic prescribing after hospital-based tonsillectomy with/without adenoidectomy. An electronic order set provided weight-based dosing and defaulted to non-opioid prescriptions (acetaminophen and ibuprofen). Patients ages 0-6 received non-opioid analgesics alone. Patients ages 7-18 received non-opioid analgesics as first-line pain control, and providers could manually add hydrocodone-acetaminophen for breakthrough pain. Opioid prescriptions and quantities were compared for 18 months of cases pre- versus post-standardization. Postoperative returns to the system were reviewed as a balancing measure. RESULTS: From 2018 through 2020, 1817 cases were reviewed. The frequency of opioid prescriptions decreased significantly post-standardization, from 64.9% to 33.5% of cases (P < .001). Opioid prescribing for young children steadily decreased from over 50% to 2.4%. Protocol adherence improved over time; outlier prescriptions were eliminated. Opioid quantities per prescription decreased by 16.3 doses on average (P < .001), and variance decreased significantly post-standardization (P < .001). The incidence of returns to the system did not change (P = .33), including returns for pain or decreased intake (P = .28). CONCLUSION: An age-based and weight-based analgesic protocol reduced post-tonsillectomy opioid prescriptions without a commensurate increase in returns for postoperative complaints. Standardized protocols can facilitate sustained changes in prescribing patterns and limit potentially unnecessary pediatric opioid exposure.

BACKGROUND: This meta-analysis aimed to evaluate the body of evidence investigating the post-operative use of non-opioid analgesic drugs and techniques in endocrine neck surgeries. Adequate pain control is crucial for successful recovery after thyroid and parathyroid surgery. Effective postoperative pain control can shorten hospital stay, improve postoperative outcomes, decrease morbidity and improve the overall patient experience. Traditionally, opioids have been the mainstay of postoperative analgesia after thyroid and parathyroid surgeries. However, the use of opioids has been linked to an increased incidence of postoperative complications. METHODS: A comprehensive systematic literature review via Medline, Embase, Web of Science and Cochrane Central Register for Controlled Trials from inception until December 26th, 2020 was conducted, followed by meta-analysis. Abstract and full-text screening, data extraction and quality assessment were independently conducted by 2 investigators. Odds ratios (OR), mean differences (MD) and 95% confidence intervals were calculated using RevMan 5.3. RESULTS: Sixty-five randomized control trials were identified from 486 unique publications. Pooled MD and 95% confidence interval for pain scores were higher for the control group at 24 h postoperatively both at rest (-0.65 [-0.92, -0.37]) and with swallowing (-0.77 [-1.37, -0.16]). These differences were statistically significant. The pooled MD and confidence interval for postoperative analgesic requirements was lower in the intervention group (-1.38 [-1.86, -0.90]). The incidence of PONV had a pooled OR of 0.67 [0.48, 0.94]. CONCLUSION: Non-opioid analgesia was superior to the control group for pain control in patients undergoing thyroid and parathyroid operations with no significant difference in complications.

BACKGROUND: Post-operative prescription of opioids has fueled an increase in opioid-associated morbidity and mortality. Alternative post-operative pain control with non-opioid pharmaceuticals can help counteract this effect. We investigated a non-opioid pain management protocol following emergent laparoscopic appendectomy and laparoscopic cholecystectomy. METHODS: Our tertiary referral center performed a prospective observational feasibility study of patients from October 2019 to 2020 who underwent emergent laparoscopic appendectomies and cholecystectomies. Patients aged 18-65 with no prior history of chronic pain or opioid abuse, no contraindications to taking acetaminophen and ibuprofen, and Glomerular Filtration Rate > 60 ml/min were included. Counseling was provided about non-narcotic pain control. Patients were not prescribed narcotics at discharge and were instead prescribed ibuprofen and acetaminophen. Patients were surveyed at their 2-week post-operative appointment to assess pain control and other patient-reported outcomes, including quality of life (QOL). RESULTS: Fifty-one patients met the inclusion criteria and completed the postoperative survey. Thirty-two were female (63%), average age 38, and BMI 30.4. 30 (59%) underwent laparoscopic appendectomy for acute non-perforated appendicitis and 21 (41%) underwent laparoscopic cholecystectomy for acute cholecystitis or symptomatic cholelithiasis. 88% of patients felt satisfied or neutral with their post-operative pain control at discharge. After 2 weeks, 34 patients (66.7%) rated QOL as high, 17 (33.3%) rated QOL as moderate, and none rated QOL as poor. Fascial suture was not associated with poor outcomes. Anxiety, depression, alcohol use, and prior abdominal surgery were not associated with increased need for post-operative narcotics. There were no significant differences between appendectomy and cholecystectomy in satisfaction with pain control or QOL (p > 0.05). CONCLUSION: Patients undergoing surgery have an increased risk of developing an opioid disorder. The NOpioid Project demonstrated a non-narcotic multimodal pain regimen can be effectively adopted in the post-operative period after an emergent laparoscopic appendectomy or emergent laparoscopic cholecystectomy.

INTRODUCTION AND HYPOTHESIS: There has been renewed interest in the management of postoperative pain after benign gynecological surgery. The purpose of the study was to determine if the use of intraoperative and immediate postoperative pain medication differs between vaginal and laparoscopic surgery in women with pelvic organ prolapse. METHODS: The study included women who had undergone pelvic organ prolapse repair between 2014 and 2019 in two tertiary care hospitals. We collected demographic data and pain medication used during and after surgery, including opioids, local anesthetics, gabapentin, ketorolac, ibuprofen, and acetaminophen. Data analyses were performed using STATA Version 16.1. A p value <0.05 was considered to indicate statistical significance. RESULTS: A total of 195 women were included in the study, with 98 in the vaginal and 97 in the laparoscopic group. Intraoperative opioid use in the two groups was similar (25 morphine milligram equivalent [MME], p = 0.34). However, women in the laparoscopic group received significantly more intravenous and local anesthesia (lidocaine: 60 vs 40 mg; bupivacaine 49.6 vs 20 ml, p < 0.001). Postoperatively, although women in the vaginal group required almost twice as many narcotics as those in the laparoscopy group (MME = 28 vs 15, p < 0.001), after controlling for confounders in the multivariate analysis, there were no differences in postoperative pain requirements between the two groups. Recovery time had a significant impact on opioid and acetaminophen use (p < 0.05). CONCLUSION: Use of pain medication was similar in the intraoperative and immediate postoperative period after pelvic organ prolapse surgery when comparing the vaginal and laparoscopic approaches after controlling for potential confounding factors.

BACKGROUND: Opioid-free anesthesia (OFA) is associated with significantly reduced cumulative postoperative morphine consumption in comparison with opioid-based anesthesia (OBA). Whether OFA is feasible and may improve outcomes in pancreatic surgery remains unclear. METHODS: Perioperative data from 77 consecutive patients who underwent pancreatic resection were included and retrospectively reviewed. Patients received either an OBA with intraoperative remifentanil (n = 42) or an OFA (n = 35). OFA included a combination of continuous infusions of dexmedetomidine, lidocaine, and esketamine. In OBA, patients also received a single bolus of intrathecal morphine. All patients received intraoperative propofol, sevoflurane, dexamethasone, diclofenac, neuromuscular blockade. Postoperative pain management was achieved by continuous wound infiltration and patient-controlled morphine. The primary outcome was postoperative pain (Numerical Rating Scale, NRS). Opioid consumption within 48 h after extubation, length of stay, adverse events within 90 days, and 30-day mortality were included as secondary outcomes. Episodes of bradycardia and hypotension requiring rescue medication were considered as safety outcomes. RESULTS: Compared to OBA, NRS (3 [2-4] vs 0 [0-2], P < 0.001) and opioid consumption (36 [24-52] vs 10 [2-24], P = 0.005) were both less in the OFA group. Length of stay was shorter by 4 days with OFA (14 [7-46] vs 10 [6-16], P < 0.001). OFA (P = 0.03), with postoperative pancreatic fistula (P = 0.0002) and delayed gastric emptying (P < 0.0001) were identified as only independent factors for length of stay. The comprehensive complication index (CCI) was the lowest with OFA (24.9 ± 25.5 vs 14.1 ± 23.4, P = 0.03). There were no differences in demographics, operative time, blood loss, bradycardia, vasopressors administration or time to extubation among groups. CONCLUSIONS: In this series, OFA during pancreatic resection is feasible and independently associated with a better outcome, in particular pain outcomes. The lower rate of postoperative complications may justify future randomized trials to test the hypothesis that OFA may improve outcomes and shorten length of stay.

OBJECTIVE: To investigate associations between multimodal analgesia and post-operative pain among patients undergoing transoral robotic surgery for oropharyngeal squamous cell carcinoma. METHODS: Records of patients who underwent surgery from 5 September 2012 to 30 November 2016 were abstracted. Associations were assessed using multivariable analysis. RESULTS: A total of 216 patients (mean age of 59.1 years, 89.4 per cent male) underwent transoral robotic surgery (92.6 per cent were human papilloma virus positive, 87.5 per cent had stage T1-T2 tumours, and 82.9 per cent had stage N0-N1 nodes). Gabapentin (n = 86) was not associated with a reduction in severe pain. Ibuprofen (n = 72) was administered less often in patients with severe pain. Gabapentin was not associated with increased post-operative sedation (p = 0.624) and ibuprofen was not associated with increased bleeding (p = 0.221). Post-operative opioid usage was not associated with surgical duration, pharyngotomy, bilateral neck dissections, tumour stage, tumour size, subsite or gabapentin. CONCLUSION: Scheduled low-dose gabapentin was not associated with improved pain control or increased respiratory depression. Ibuprofen was not associated with an increased risk of bleeding and may be under-utilised.

INTRODUCTION: Our goal was to describe variation in procedural benzodiazepine and post-vasectomy nonopioid pain and opioid prescription dispense events, and multilevel factors associated with the probability of an opioid refill. METHODS: Patients (40,584) undergoing vasectomies in the U.S. Military Health System between January 2016-January 2020 were included in this observational retrospective study. The main outcome was the probability of being dispensed an opioid prescription refill within 30 days post-vasectomy. Bivariate analyses examined the relationships between patient- and care-level characteristics, prescription dispense and 30-day opioid prescription refill. A generalized additive mixed-effects model and sensitivity analyses examined factors associated with opioid refill. RESULTS: There was wide variation in procedural benzodiazepine (32%) and post-vasectomy nonopioid (71%) and opioid (73%) prescription dispense patterns across facilities. Only 5% of the patients dispensed opioids received a refill. Probability of an opioid refill was associated with race (White), younger age, opioid dispense history, documented mental health or pain condition, lack of post-vasectomy nonopioid pain medication dispense events and higher dispensed post-vasectomy opioid prescription dose; albeit the effect of dose did not replicate in sensitivity analyses. CONCLUSIONS: Despite the wide variation in vasectomy-related pharmacological pathways across a large health care system, most patients do not require an opioid refill. Significant variation in prescribing practices indicated racial inequities. Given the low rates of opioid prescription refill, combined with the wide variation in opioid prescription dispense events and American Urological Association recommendations for conservative opioid prescribing after vasectomy, intervention to address excessive opioid prescribing is warranted.
RESUMEN
INTRODUCTION: In an effort to decrease physician contribution to the opioid crisis, we utilized a narcotic free pathway (NFP) after urethroplasty. Our objectives were to demonstrate feasibility of a NFP and identify patients at higher risk for requiring postoperative narcotics. MATERIALS AND METHODS: We implemented a NFP for patients undergoing urethroplasty. Pain was assessed using the Likert scale (1-10). Narcotic use was quantified using oral morphine equivalents (OMEs). RESULTS: Forty-six patients underwent urethroplasty following the NFP over a 7-month period. Fifteen patients were excluded, leaving 31 patients in the final analysis. Postintervention data was compared to 30 patients who underwent urethroplasty prior to implementation of the NFP. The groups had similar demographics except for a history of heroin abuse (0% preintervention, 12.9% postintervention, p = 0.04). Surgical characteristics were not statistically different aside from length of surgery (183.6 minutes preintervention, 145.5 minutes postintervention, p = 0.01). The mean [SD] perioperative OME use preintervention was 194.9 [151] mg, compared to 40.4 [111.9] mg postintervention (p < 0.001). Six patients postintervention were discharged with a narcotic prescription (mean 27.5 mg OME) compared to 26 patients preintervention (mean 76 mg OME) (p < 0.001). There was no difference in pain scores at any time interval. Patients with a history of chronic opioid use were more likely to require narcotics (OR 5.33, CI 1-28.44). CONCLUSIONS: The narcotic free pathway resulted in a dramatic reduction in narcotic prescriptions without a significant difference in postoperative pain scores. Opioid use can be minimized following urethral and perineal surgery.

OBJECTIVE: To study the impact of routine ketorolac administration during oocyte retrieval on the proportion of patients who require postoperative narcotics for analgesia. DESIGN: Retrospective cohort study. SETTING: Single, university-affiliated infertility clinic. PATIENTS: All women undergoing oocyte retrieval between July and November 2016 (non-ketorolac group [NKG]; n = 826) and April-August 2017 (ketorolac group, KG; n = 1780). INTERVENTIONS: A single 30 mg intravenous dose of ketorolac was administered after the oocyte retrieval procedure. MAIN OUTCOME MEASURES: The number of patients who required postoperative narcotic analgesia, postoperative complication rate, and fresh embryo transfer pregnancy outcomes were examined. RESULTS: In the KG, we found a significant decrease in the patients who required narcotics after oocyte retrieval compared with the NKG (12% KG vs. 25.5% NKG). We found no significant change in the clinical pregnancy rate (CPR) resulting from fresh embryo transfer after our intervention (NKG CPR 32.6%, KG CPR 32.4%). Furthermore, there was no increase in postoperative bleeding complications in the KG. CONCLUSIONS: Routine use of ketorolac at the time of oocyte retrieval may decrease the rate of postoperative opioid use without adversely impacting pregnancy and complication rates.
RESUMEN
PURPOSE: Breast-conserving surgery (BCS) is a surgical method designed to minimize intraoperative tissue injury. Although this technique is minimally invasive, it can cause significant postoperative pain and may be a risk factor for persistent pain. Erector spinae plane block (ESPB) is an easy interfascial plane block for analgesia in patients undergoing breast surgery. The primary outcome was the numeric rating scale scores measured separately on the breast and axilla. Secondary outcomes included correlation between pain score and skin sensitivity test. METHODS: Forty patients were divided into 2 groups (ESPB group and control group). Patients in the ESPB group received an ESPB 30 minutes before the induction of general anesthesia, whereas patients in the control group did not receive any regional analgesia during the perioperative period. RESULTS: Median pain scores of the breast were significantly lower in the ESPB group than that in the control group at 12, 24, and 48 hours after surgery. However, the median pain scores of the axilla were not significantly different between the groups, and the pain score was unrelated to skin sensitivity. CONCLUSION: ESPB can effectively alleviate acute postoperative pain with an opioid-sparing analgesic technique in patients undergoing BCS, and a strong correlation is lacking between pain scores and skin sensitivity test.
RESUMEN
OBJECTIVE: To evaluate the pharmacokinetics and pharmacodynamics, dosing, efficacy, and safety of ketorolac in postoperative patients younger than 6 months of age. METHODS: PubMed (1988-July 2020), Medline (1946-July 2020), and EBSCO Discovery Service (1988-July 2020) were searched to identify relevant published articles using the following search terms: ketorolac, neonate, infant. English-language articles evaluating the use of ketorolac in infants younger than 6 months of age were included. RESULTS: Eight reports that included 239 infants receiving ketorolac were included. Of the included patients, 237 were younger than 6 months of age. Ketorolac exhibits rapid elimination of the analgesia-producing S (-) isomer, elimination half-life of 0.83 hours. Most patients received 0.5 mg/kg/dose every 6 hours for 48 to 72 hours. Analgesia was demonstrated by reduced use of open-label morphine and significant lowering of Neonatal/Infant Pain Scale scores. Adverse effects were minimal when ketorolac was used in term neonates and infants without baseline renal dysfunction. CONCLUSIONS: Randomized placebo-controlled trials of ketorolac use in this population are lacking; however, most published reports noted efficacy and safety with ketorolac in properly selected infants.
RESUMEN
BACKGROUND: Information on the prevalence of common imaging findings among patients without back pain in spine imaging reports might affect pain medication prescribing for patients with back pain. Prior research on inserting this text suggested a small reduction in opioid prescribing. OBJECTIVE: To evaluate the effect of epidemiologic information in spine imaging reports on non-opioid pain medication prescribing for primary care patients with back pain. DESIGN: Post hoc analysis of the Lumbar Imaging with Reporting of Epidemiology cluster-randomized trial. PARTICIPANTS: A total of 170,680 patients aged ≥ 18 years from four healthcare systems who received thoracolumbar, lumbar, or lumbosacral spine imaging from 2013 to 2016 and had not received a prescription for non-opioid pain medication in the preceding 120 days. INTERVENTION: Text of age- and modality-specific epidemiologic benchmarks indicating the prevalence of common findings in people without back pain inserted into thoracolumbar, lumbar, or lumbosacral spine imaging reports at intervention clinics. MAIN MEASURES: Primary outcomes: any non-opioid prescription within 90 days after index imaging, overall, and by sub-class (skeletal muscle relaxants, NSAIDs, gabapentinoids, tricyclic antidepressants, benzodiazepines, duloxetine). SECONDARY OUTCOMES: count of non-opioid prescriptions within 90 days, overall, and by sub-class. KEY RESULTS: The intervention was not associated with the likelihood of patients receiving at least one prescription for new non-opioid pain-related medications, overall (adjusted OR, 1.02; 95% CI, 0.97-1.08) or by sub-class. The intervention was not associated with the number of prescriptions for any non-opioid medication (adjusted incidence rate ratio [IRR], 1.02; 95% CI, 0.99-1.04). However, the intervention was associated with more new prescriptions for NSAIDs (IRR, 1.12) and tricyclic antidepressants (IRR, 1.11). CONCLUSIONS: Inserting epidemiologic text in spine imaging reports had no effect on whether new non-opioid pain-related medications were prescribed but was associated with the number of new prescriptions for certain non-opioid sub-classes.
