Abstract Background: Extrapleural paravertebral local anaesthetic catheters are an effective method of post-operative analgesia. We investigated if delivery of ropivacaine via programmed intermittent boluses provided superior analgesia to continuous infusion alone in patients after thoracic surgery. Methods: A single-centre, retrospective study of 84 adult patients who received an extrapleural paravertebral catheter following thoracic surgery was performed. Patients were stratified into two groups based on the percentage of the total daily ropivacaine dose delivered as a bolus: continuous infusion (< 10%; n = 29) and programmed intermittent bolus (> 10%; n = 55). Outcomes included opioid consumption, pain scores, and ketamine use. Results: Both groups were comparable. Mean (standard deviation) oral morphine equivalent daily dose consumption on day one, the primary outcome, was 173.4mg (139.7mg) for the continuous infusion group compared to 129.2mg (100.4mg) for the programmed intermittent bolus group, p = 0.10. On day two, the mean (standard deviation) was 149.8mg (130.2mg) and 102.5mg (94.6mg) respectively, p = 0.08. On day three this reached significance with 178.1mg (150.6mg) for the continuous infusion group compared to 80.1mg (74.6mg) for the programmed intermittent bolus group, p = 0.001. There was also a reduction in the number of patients requiring ketamine in the programmed intermittent bolus group on day two (p = 0.02) and day three (p = 0.04). There was no difference in pain scores. Conclusion: In patients receiving extrapleural paravertebral catheters after thoracic surgery, the delivery of ropivacaine via programmed intermittent boluses may provide superior analgesia compared to continuous infusion alone.

Background Postoperative pain management following donor nephrectomy can prove challenging for immediate discharge on postoperative day 1 or 2. Although the standard for pain control is utilization of opioids, this increases the risk of postoperative ileus and, if continued inappropriately, increases excess opioids circulating in the community. One strategy that proposes to limit postoperative opioids in kidney donors is the continuous infusion of local anesthetics (CILA), though the effect on patient outcomes is unclear. Objective The purpose of this study was to evaluate the effectiveness of postoperative CILA to decrease opioid usage in kidney donors who undergo laparoscopic nephrectomy. Methods A retrospective analysis was conducted of kidney donors who underwent laparoscopic nephrectomy and received CILA (CILA group) compared with kidney donors who received standard-of-care (SOC) postoperative analgesia. The primary outcome was the mean total oral morphine equivalents (OMEs) administered following surgery. Results A total of 176 kidney donors were evaluated, 88 in each group. The mean OME administered in the CILA group was significantly higher than in the SOC group: 194.8 versus 133.5 mg ( P = 0.003). Mean total postoperative administration of acetaminophen was also increased in the CILA group: 3736.9 versus 2611.6 mg ( P = 0.0041). Mean length of stay following surgery was higher in the kidney donors who received CILA, whereas return to bowel function, time to ambulation, and pain scores were not significantly different. Conclusion and Relevance This report demonstrated that CILA is not an effective modality to reduce opioid utilization or improve recovery in kidney donors following laparoscopic nephrectomy.

Background:TNFα-inhibitor (TNFi) therapy is effective in controlling several rheumatic diseases and has been shown to reduce pain in patients with arthritis. Opioids are often prescribed for chronic pain, a common issue in inflammatory joint disease.Objectives:To explore the impact of the initiation of TNFi therapy as a first-line biologic disease-modifying anti-rheumatic drug (DMARD) on the prescription rates of opioids in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and undifferentiated arthritis (UA) in Iceland.Methods:All patients receiving biologic DMARD therapy for rheumatic diseases in Iceland are registered in a nationwide database (ICEBIO). The Icelandic Directorate of Health operates a Prescription Medicines Register that includes over 90% of all drug prescriptions in Iceland. The study group included patients with RA, PsA, AS, and UA registered in ICEBIO and for each of them five randomly selected comparators from the general population matched on age, sex, and calendar time. On February 1st2016 we extracted data on all filled opioid analgesic prescriptions two years before and two years after the date of TNFi initiation.Results:Data from 359 RA, 217 AS, 251 PsA and 113 UA patients and 4700 comparators were collected. In total, 75% of patients compared to 43% of comparators received ≥1 opiate prescription during the study period. The proportion of patients using opioids (regardless of dose) two years prior to TNFi initiation was 41%, increasing to 49% the following year. After TNFi initiation the proportion returned to 40% (Figure 1). Despite this, the mean yearly opiate dose used by the patients followed a rising trajectory throughout the study period (Figure 2). In total, patients were prescribed nearly 6 times more opioids than the comparators, corresponding to a bootstrapped mean (95% CI) dose of 818 (601-1073) mg MED per patient and year compared to 139 (111-171) mg for comparators.Figure 1.Percental distributions of opioid analgesic use by dose (according to dispensed prescriptions) among patients with inflammatory arthritis (A) and matched comparators (B). All doses are oral morphine equivalent dose (MED) in milligrams.Figure 2.Bootstrapped mean oral morphine equivalent dose per person per year for patients with inflammatory arthritis (above) and age and sex matched comparators (below). Box edges represent 25-75thpercentiles and whiskers 95% confidence intervals.Conclusion:Three out of four patients with inflammatory arthritis in Iceland use opioid analgesics in the two years prior to and/or after the initiation of TNFi therapy and the mean doses were significantly higher than in matched comparators. The proportion of patients receiving opioids increased before TNFi therapy and then decreased again to the previous level. The initiation of the first-line TNFi did not reduce opioid consumption by dose at the group level. On the contrary, there was a trend towards increasing doses over time in both patients and comparators, possibly reflecting the development of opiate tolerance.Table 1.Baseline demographic data.

197 Background: Inpatients with cancer frequently undergo conversions from IV to PO hydromorphone (HM) or opioid rotation (OR) from IV HM to another PO opioid prior to discharge. Currently used conversion ratios (CR) between IV and PO HM range from 2-5 and opioid rotation ratios (ORR) between IV HM and oral morphine equivalent daily dose (MEDD) range from 10-20. This large variation in ratios may lead to uncontrolled pain or overdosing. Our aim was to determine the accurate CR from IV to PO HM and ORR from IV HM to PO morphine and oxycodone (measured as MEDD). Methods: We reviewed records of 4745 consecutive inpatient palliative care consults in our institute during 2010-14 for patients who underwent conversion from IV to PO HM or OR from IV HM to PO morphine or oxycodone. Patient characteristics, symptoms and opioid doses were determined in patients successfully discharged on oral opioids without readmission within 1 week. Linear regression analysis was used to estimate the CR or ORR between the 24 hour IV HM mg dose prior to conversion to PO and the oral opioid mg dose used in the 24 hours prior to discharge. Results: Among 394 eligible patients on IV HM, 147 underwent conversion to PO HM and 247 underwent OR to oral morphine (163) or oxycodone (84). Mean age was 54 years, 39% were male, and 95% had advanced cancer. Median time between conversion to PO and discharge was 2 days. In 147 patients the median CR (IQR) from IV to PO HM was 2.5 (2.1-2.7) and correlation of IV to PO dose of HM was .95 (P < .0001). The median CR was 2.5 in patients receiving < 30mg of IV HM/day and 2.1 in patients receiving ≥ 30mg of HM/day (P = .004). In 247 patients the median ORR (IQR) from IV HM to MEDD was 11.5 (10-13) and correlation of IV HM to MEDD was .93 (P < .0001). The median ORR was 11.5 in patients receiving < 30mg of IV HM/day and 9.9 in patients receiving ≥ 30mg of HM/day (P = .0004). ORR from IV HM to MEDDs obtained from morphine (11) and oxycodone (12.1) were significantly different (P = .0023). The CR and ORR were not significantly impacted by other variables. Conclusions: The median CR from IV to PO HM is 2.5 and ORR from IV HM to MEDD is 11.5. This implies that 1 mg IV HM is equivalent to 2.5 mg PO HM and 11.5 mg MEDD. HM may cause hyperalgesia at doses ≥ 30 mg/day and thereby requires a lower ORR to other opioids.

Background: Total knee arthroplasty (TKA) can lead to chronic pain and prolonged postoperative opioid use. There are few evidence-based interventions to prevent these outcomes. Recently, β-blockers have emerged as possible novel analgesics. Objectives: The objective of this study was to determine whether perioperative β-blocker use is associated with reduced prolonged postoperative opioid use after TKA. Study Design: This study used a retrospective cohort design. Setting: The research took place within Department of Veterans Affairs hospitals in the United States between April 2012 and April 2016. Methods: Patients: IRB approval was obtained to examine the records of Veterans Affairs (VA) patients undergoing TKA. Patients using opioids 60 days before surgery were excluded. Intervention: The intervention being investigated was perioperative β-blocker use, overall and by class. Measurement: Oral morphine equivalent usage through postoperative day 1 and prescription opioid refills through 30, 90, and 365 days after TKA were recorded. Adjusted models were created controlling for relevant demographic and comorbidity covariates. A secondary analysis examined the same outcomes separated by β-blocker class. Results: The cohort was 93.8% male with a mean age of 66 years. Among the 11,614 TKAs that comprised the cohort, 2,604 (22.4%) were performed on patients using β-blockers. After adjustment, β-blocker use was associated with reduced opioid use through 30 days after surgery (odds ratio [OR] 0.89 [95% confidence interval (CI), 0.80-0.99], P = .026). Selective β-blockers were associated with reduced opioid use at 30 days (OR 0.88 [95% CI, 0.78-0.98], P = .021), and nonselective β-blockers were associated with reduced oral morphine equivalent usage through postoperative day 1 (β = -17.9 [95% CI, -29.9 to -5.8], P = .004). Limitations: Generalizability of these findings is uncertain, because this study was performed on a cohort of predominantly white, male VA patients. This study also measured opioid use, but opioid use is not a perfect surrogate for pain. Nevertheless, opioid use offers value as an objective measure of pain persistence in a national cohort for which patient-reported outcomes are otherwise unavailable. Conclusions: Perioperative β-blocker use was associated with reduced prescription opioid use at 30 days after surgery. Both selective and nonselective β-blockers were associated with reduced opioid use when analyzed individually.

Objective. Serratus anterior plane block (SAPB) provides effective thoracic analgesia. This systematic review and meta-analysis was conducted to assess the safety and efficacy of SAPB for postoperative analgesia after breast surgery. Methods. A systematic literature search was performed using Embase, PubMed, Web of Science, and the Cochrane Library for eligible randomised controlled trials. The primary outcomes involved the administration of intraoperative and postoperative opioids. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used for rating the quality of evidence for making recommendations. Results. Overall, 13 studies comprising 826 patients met the inclusion criteria (412 in the SAPB group and 414 in the control group). Patients treated with SAPB exhibited a significantly lower postoperative opioid consumption (mean difference, −38.51 mg of oral morphine equivalent; 95% confidence interval (CI), −60.97 to −16.05; P < 0.01 ; I2 = 100%), whereas no difference was observed in the intraoperative opioid consumption (mean difference, −9.85 mg of oral morphine equivalent; 95% CI, −19.52 to −0.18; P = 0.05 ; I2 = 94%). In addition, SAPB significantly decreased the occurrence of postoperative nausea and vomiting (risk ratio, 0.32; 95% CI, 0.19–0.55; P < 0.05 ;I2 = 38%) and reduced pain scores during the postoperative period (1 h: standardised mean difference (SMD), −1.23; 95% CI, −2.00 to −0.45; I2 = 92%; 2 h: SMD, −0.71; 95% CI, −1.00 to −0.41; I2 = 48%; 4 h: SMD, −1.52; 95% CI, −2.77 to −0.27; I2 = 95%; 6 h: SMD, −0.80; 95% CI, −1.51 to −0.08; I2 = 81%; 8 h: SMD, −1.12; 95% CI, −1.98 to −0.27; I2 = 92%; 12 h: SMD, −0.78; 95% CI, −1.21 to −0.35; I2 = 83%; and 24 h: SMD, −0.71; 95% CI, −1.20 to −0.23; I2 = 87%; P < 0.05 for all). Conclusion. SAPB was safe and effective after breast surgery to relieve postsurgical pain. However, additional well-developed trials are required to validate these findings.

BackgroundEvidence regarding the role of cannabinoids in managing acute postoperative pain is conflicting. The purpose of this systematic review and meta-analysis was to determine the analgesic efficacy of perioperative cannabinoid compounds for acute pain management after surgery.MethodsOriginal research articles evaluating the addition of cannabinoids to standard opioid-based systemic analgesia (Control) in the postoperative period were sought. Our primary outcomes were cumulative oral morphine equivalent consumption and rest pain severity at 24 hours postoperatively. We also assessed analgesic consumption in the postanesthesia care unit (PACU), pain scores in PACU, 6 and 12 hours postoperatively, and opioid-related and cannabinoid-related side effects, patient satisfaction, and quality of recovery as secondary outcomes.ResultsEight randomized controlled trials (924 patients) and four observational studies (4259 patients) were analyzed and included. There were insufficient data to pool for quantification of differences in cumulative oral morphine equivalent consumption and rest pain severity at 24 hours postoperatively with the addition of cannabinoids in comparison to Control. Qualitative synthesis revealed no differences in cumulative oral opioid consumption or pain at rest 24 hours postoperatively with the addition of cannabinoids in comparison to Control. Patients receiving cannabinoids appeared to have an increased weighted mean difference 95% CI of pain at 12 hours by 0.83 cm (0.04 to 1.63) (p=0.04). Patients receiving cannabinoids also appeared to have 3.24 times increased odds of developing hypotension postoperatively (95% CI 1.12 to 9.36) (p=0.03). Qualitative and quantitative synthesis revealed no differences in any other secondary outcomes.ConclusionsOur quantitative and qualitative review of the literature suggests that the analgesic role of perioperative cannabinoid compounds is limited, with no clinically important benefits detected when cannabinoids are added to traditional systemic analgesics compared with traditional systemic analgesics alone. Notably, there appears to be a signal towards increased postoperative pain and hypotension associated with the addition of perioperative cannabinoids to traditional systemic analgesics. These results do not support the routine use of cannabinoids to manage acute postoperative pain at the present time.

Safety concerns are a barrier to prescribing benzodiazepines (BDZs) and opioids in interstitial lung disease (ILD). We therefore examined the association of BDZs and opioids on risk of admission to hospital and death.We conducted a population-based longitudinal cohort study of fibrotic ILD patients starting long-term oxygen therapy in Sweden between October 2005 and December 2014. Effects of BDZs and opioids on rates of admission to hospital and mortality were analysed using Fine–Gray and Cox regression while adjusting for potential confounders.We included 1603 patients (61% females). BDZs were used by 196 (12%) patients and opioids were used by 254 (15%) patients. There was no association between BDZs and increased admission. Treatment with high- versus low-dose BDZs was associated with increased mortality (subdistribution hazard ratio (SHR) 1.46, 95% CI 1.08–1.98 versus 1.13, 95% CI 0.92–1.38). Opioids showed no association with increased admission. Neither low-dose opioids (≤30 mg·day−1 oral morphine equivalent) (SHR 1.18, 95% CI 0.96–1.45) nor high-dose opioids (>30 mg·day−1 oral morphine equivalent) (SHR 1.11, 95% CI 0.89–1.39) showed association with increased mortality.This first ever study to examine associations between BDZ and opioid use and harm in ILD supports the use of opioids and low-dose BDZs in severely ill patients with respiratory compromise.

Background Spinal morphine is the mainstay of postcesarean analgesia. Quadratus lumborum block has recently been proposed as an adjunct or alternative to spinal morphine. The authors evaluated the analgesic effectiveness of quadratus lumborum block in cesarean delivery with and without spinal morphine. Methods Randomized trials evaluating quadratus lumborum block benefits in elective cesarean delivery under spinal anesthesia were sought. Three comparisons were considered: spinal morphine versus spinal morphine and quadratus lumborum block; spinal morphine versus quadratus lumborum block; and no block or spinal morphine versus quadratus lumborum block. The two coprimary outcomes were postoperative (1) 24-h cumulative oral morphine equivalent consumption and (2) pain at 4 to 6 h. Secondary outcomes included area under the curve pain, time to analgesic request, block complications, and opioid-related side effects. Results Twelve trials (924 patients) were analyzed. The mean differences (95% CIs) in 24-h morphine consumption and pain at 4 to 6 h for spinal morphine versus spinal morphine and quadratus lumborum block comparison were 0 mg (−2 to 1) and −0.1 cm (−0.7 to 0.4), respectively, indicating no benefit. For spinal morphine versus quadratus lumborum block, these differences were 7 mg (−2 to 15) and 0.6 cm (−0.7 to 1.8), respectively, also indicating no benefit. In contrast, for no block or spinal morphine versus quadratus lumborum block, improvements of −18 mg (−28 to −7) and −1.5 cm (−2.4 to −0.6) were observed, respectively, with quadratus lumborum block. Finally, for no block or spinal morphine versus quadratus lumborum block, quadratus lumborum block improved area under the 48-h pain curve by −4.4 cm · h (−5.0 to −3.8), exceeding the clinically important threshold (3.96 cm · h), but no differences were observed in the other comparisons. Conclusions Moderate quality evidence suggests that quadratus lumborum block does not enhance analgesic outcomes when combined with or compared with spinal morphine. However, the block improves postcesarean analgesia in the absence of spinal morphine. The clinical utility of this block seems limited to situations in which spinal morphine is not used.

Current pain treatment guidelines advise against providing analgesics for postoperative pain using intramuscular injections, as this generally provides poor pain relief. However, this route remains the most prevalent treatment method. Intravenous or epidural patient-controlled-analgesia methods reduce pain effectively but are expensive, labor intensive, and available to only a limited number of patients. We propose administering the analgesics using oral analgesics and have developed a simple protocol for treating postoperative pain by use of oral morphine. After a variety of orthopedic surgeries, patients were given “around-the-clock,” oral, immediate-release morphine. Efficacy of the treatment (pain scores and adverse effects) was assessed 24 ± 2 hours after surgery. Data were collected prospectively from 95 patients, who received an average of 61 ± 30 (SD) mg morphine. Average pain scores were 2.4/10 (± 1.4) at rest and 4.0/10 (± 1.4) during movement in bed. Nausea and vomiting, the most common adverse effects, were reported by 22 (23 percent) patients. Naloxone was not administered to any of the patients. Oral morphine given in the early postoperative time to patients after a variety of orthopedic surgeries was effective and safe.
