Single Chest Drain Practice Reduces Discharge Opioid Prescriptions in Thoracic Surgery

Introduction Chest drains are placed following pulmonary resection to promote lung re-expansion. The superiority of two chest drains at preventing postoperative complications has not been established, and practice remains largely dictated by surgeon preference. We sought to compare patient outcomes based on number of chest drains used. Methods This is a retrospective analysis including patients undergoing lobectomies and segmentectomies between March 2016 and April 2020. Patients were categorized based on number of chest drains placed and were matched 1:1 using the nearest neighbor (greedy) technique. Our primary outcome was opioid prescriptions at discharge (in morphine equivalent daily dose [MEDD]). Associations were tested using multilevel mixed-effects regression to account for variability between surgeons. Results A total of 1,094 patients met inclusion criteria. Single chest drain was used in 922 patients, whereas 172 had two chest tubes. After matching, there were 111 patients in each group. In multilevel mixed-effects logistic regression, patients treated with a single chest drain received fewer opioid prescriptions (β: −194 MEDD, 95% confidence interval [CI]: −302 to −86 MEDD, p < 0.01), were more likely to be opioid-free at hospital discharge (odds ratio [OR] = 2.11, 95% CI: 1.08–4.12, p = 0.03), and had lower readmission rates within 30 days (OR = 0.33, 95% CI: 0.13–0.84, p = 0.02). Single chest drain practice did not affect the risk of pulmonary complications and there was no statistically significant difference in length of hospital stay (3 days [interquartile range: 2–5] vs. 4 days [3–6], p = 0.08). Conclusion Single chest drain practice in lobectomies and segmentectomies was associated with less opioid prescription requirement without any increase in complications.

Peripheral nerve blocks in advanced cancer pain: retrospective case series

ObjectivesPatients with cancer often suffer severe pain that is not relieved with systemic analgesics and requires further treatment options. This study aims to investigate whether peripheral nerve blocks are a feasible treatment option in patients with incurable cancer who suffer from severe pain.MethodsAll patients with advanced cancer who received a peripheral nerve block for the management of pain at the Tampere University Hospital between January 2015 and December 2018 were included in this retrospective study. The characteristics of the patients’ features of the nerve blocks, opioid dosing (daily morphine equivalent) before and after the blocks, and patient-reported pain relief following peripheral block were assessed from the medical records.ResultsSixteen of the 17 patients included in this study received pain relief through a nerve block. Daily opioid dose was decreased with the block in 12 (71%) patients with a median change in daily morphine equivalent of −20 mg (IQR: −180 to 9). One infection of the catheter and two other transient adverse events occurred, but none was serious or fatal.ConclusionsPeripheral nerve blocks seem safe and may provide considerable analgesia and decrease the need for opioids in patients with advanced cancer.

Intrathecal Analgesia Via a Percutaneous Port For the Management of Movement-Evoked Breakthrough Cancer Pain of Refractory Lower Extremity Cancer Pain: A Retrospective Review and Commentary

Background and Objectives: Intrathecal analgesia (ITA) is a trusty treatment option for refractory and intractable cancer pain. However, there is still no general consensus on the analgesic effect of movement-evoked breakthrough pain (MEBTP) in the ITA setting. This study examined the effect of patient-controlled intrathecal analgesia (PCIA) on analgesic efficacy, emphasizing movement evoked breakthrough pain (MEBTP) in patients with refractory lower extremity cancer pain. Methods: A retrospective chart review included all patients with refractory lower extremity cancer pain who received Intrathecal morphine infusion therapy via percutaneous port (IMITPP) at our hospital between January 2017 and December 2020. Data on the numerical pain rating scales (NRS) scores, opioid doses, and complications were collected from medical records prior to IMITPP and at a one-month postimplant visit.Results: A total of 16 patients were included in the study group. Mean SRPI (spontaneous resting pain intensity) decreased from 8.75 pre- IMITPP to 3.75 post- IMITPP, (P < 0.001); mean MEPI (movement-evoked breakthrough pain intensity) fell from 8.83 pre- IMITPP to 4.25 post- IMITPP (P < 0.001); mean daily morphine equivalent dosing decreased from 360 mg/d to 48mg/d (P< 0.001); mean daily morphine equivalent dosing for MEBTP decreased from 87 mg/d to 6 mg/d (P< 0.001). Both total and breakthrough dosing of conventional opioid medications significantly decreased following the initiation of ITT with PCIA. The mean perceived time to onset with conventional movement evoked breakthrough medications was 38 minutes, and the mean perceived time to onset with PCIA was 8 minutes (P < 0.001). Conclusions: IMITPP was associated with improved pain control in patients with refractory lower extremity cancer pain. Compared with conventional MEBTP medication, appropriate PCIA provided superior analgesia and a much faster onset of action.

Local Infiltration Analgesia Versus Femoral Nerve Block for Pain Control in Anterior Cruciate Ligament Reconstruction: A Systematic Review With Meta-analysis

Background: Anterior cruciate ligament reconstruction (ACLR) is often performed on an outpatient basis; thus, effective pain management is essential to improving patient satisfaction and function. Local infiltration analgesia (LIA) and femoral nerve block (FNB) have been commonly used for pain management in ACLR. However, the comparative efficacy and safety between the 2 techniques remains a topic of controversy. Purpose: To compare pain reduction, opioid consumption, and side effects of LIA and FNB after ACLR. Study Design: Systematic review; Level of evidence, 3. Methods: A systematic search of MEDLINE, Embase, and Cochrane Library databases was performed to identify studies comparing pain on the visual analog scale (a 100-mm scale), total morphine-equivalent consumption, and side effects between the 2 techniques after ACLR at the early postoperative period. The LIA was categorized into intra-articular injection and periarticular injection, and subgroup analyses were performed comparing either intra-articular injection or periarticular injection with FNB. Two reviewers performed study selection, risk-of-bias assessment, and data extraction. Results: A total of 10 studies were included in this systematic review and meta-analysis. In terms of VAS pain scores, our pooled analysis indicated that FNB was significantly more effective at 2 hours postoperatively compared with LIA (mean difference, 8.19 [95% confidence interval (CI), 0.75 to 15.63]; P = .03), with no significant difference between the 2 techniques at 4, 8, and 12 hours postoperatively; however, LIA was significantly more effective at 24 hours postoperatively compared with FNB (mean difference, 5.61 [95% CI, −10.43 to −0.79]; P = .02). Moreover, periarticular injection showed a significant improved VAS pain score compared with FNB at 24 hours postoperatively (mean difference, 11.44 [95% CI, −20.08 to −2.80]; P = .009), and the improvement reached the threshold of minimal clinically important difference of 9.9. Total morphine-equivalent consumption showed no difference between the 2 techniques, and side effects were unable to be quantified for the meta-analysis because of a lack of data. Conclusion: Compared with FNB, LIA was not as effective at 2 hours, comparable within 12 hours, and significantly more effective at 24 hours postoperatively for reducing pain after ACLR. Total morphine-equivalent consumption showed no significant differences between the 2 techniques.

Efficacy of Ultrasound-Guided Serratus Anterior Plane Block for Postoperative Analgesia in Patients Undergoing Breast Surgery: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

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.

Persistent Postoperative Opioid Prescription Fulfillment and Peripheral Nerve Blocks for Ambulatory Shoulder Surgery: A Retrospective Cohort Study

Background There is need to identify perioperative interventions that decrease chronic opioid use. The authors hypothesized that receipt of a peripheral nerve block would be associated with a lower incidence of persistent postoperative opioid prescription fulfillment. Methods This was a retrospective population-based cohort study examining ambulatory shoulder surgery patients in Ontario, Canada. The main outcome measure was persistent postoperative opioid prescription fulfillment. In opioid-naive patients (no opioid prescription fulfillment in 90 days preoperatively), this was present if an individual fulfilled an opioid prescription of at least a 60-day supply during postoperative days 90 to 365. In opioid-exposed (less than 60 mg oral morphine equivalent dose per day within 90 days preoperatively) or opioid-tolerant (60 mg oral morphine equivalent dose per day or above within 90 days preoperatively) patients, this was classified as present if an individual experienced any increase in opioid prescription fulfillment from postoperative day 90 to 365 relative to their baseline use before surgery. The authors’ exposure was the receipt of a peripheral nerve block. Results The authors identified 48,523 people who underwent elective shoulder surgery from July 1, 2012, to December 31, 2017, at one of 118 Ontario hospitals. There were 8,229 (17%) patients who had persistent postoperative opioid prescription fulfillment. Of those who received a peripheral nerve block, 5,008 (16%) went on to persistent postoperative opioid prescription fulfillment compared to 3,221 (18%) patients who did not (adjusted odds ratio, 0.90; 95% CI, 0.83 to 0.97; P = 0.007). This statistically significant observation was not reproduced in a coarsened exact matching sensitivity analysis (adjusted odds ratio, 0.85; 95% CI, 0.71 to 1.02; P = 0.087) or several other subgroup and sensitivity analyses. Conclusions This retrospective analysis found no association between receipt of a peripheral nerve block and a lower incidence of persistent postoperative opioid prescription fulfillment in ambulatory shoulder surgery patients.

Postoperative Use of Ketorolac Improves Pain Management and Decreases Narcotic Use Following Primary Cleft Palate Surgery

Objective To study the efficacy and safety profile of ketorolac in cleft palate surgery. Design Retrospective analysis of patients who underwent primary cleft palate surgery and received either postoperative ketorolac or opioids. Setting Tertiary care children's hospital. Patients, Participants Eighty-nine patients enrolled who were all younger than 36 months of age, not dependent on a gastrostomy tube, with no history of bleeding disorders, and had undergone their primary cleft palate procedure by one specific surgeon between January 2010 and June 2019. Interventions n/a. Main Outcome Measure Morphine equivalent dose (MED), Face, Legs, Activity, Cry, Consolability (FLACC) score, length of stay (LOS), total oral intake (mL), total oral intake/LOS, and postoperative adverse events between ketorolac and no ketorolac groups. Results MED, FLACC score, and LOS were significantly lower in the ketorolac group compared to the no ketorolac group. One patient in the ketorolac group had a bleeding event. Conclusions Use of ketorolac significantly decreased narcotic usage and pain scores as reported by the FLACC score. Moreover, postoperative bleeding was rare in both ketorolac and no ketorolac groups.

Impact of a tiered discharge opioid algorithm on prescriptions and patient-reported outcomes after open gynecologic surgery

ObjectiveTo compare discharge opioid refills, prescribed morphine equivalent dose and quantity, and longitudinal patient-reported outcomes before and after implementation of a tiered opioid prescribing algorithm among women undergoing open gynecologic surgery within an enhanced recovery after surgery program.MethodsWe compared opioid prescriptions, clinical outcomes, and patient-reported outcomes among 273 women. Post-discharge symptom burden was collected up to 42 days after discharge using the validated 27-item MD Anderson Symptom Inventory and analyzed using linear mixed effects models and Kaplan–Meier curves for symptom recovery.ResultsAmong 113 pre-implementation and 160 post-implementation patients there was no difference in opioid refills (9.7% vs 11.3%, p=0.84). The post-implementation cohort had a significant reduction in median morphine equivalent dose (112.5 mg vs 225 mg, p<0.01), with no difference in median hospital length of stay (3 days vs 3 days, p=1.0) or 30-day readmission rate (9.4% vs 7.1%, p=0.66). There was no difference in patient-reported pain between the pre- and post-implementation cohorts on the day of discharge (severity 4.93 vs 5.14, p=0.53) or in any patient-reported symptoms, interference measures, or composite scores by post-discharge day 7. The median recovery time for most symptoms was 7 days, except for pain (14 days), fatigue (18 days), and physical interference (21 days), with no differences between cohorts.ConclusionsAfter implementation of a tiered opioid prescribing algorithm, the quantity and dose of discharge opioids prescribed decreased with no change in post-operative refills and without negatively impacting patient-reported symptom burden or interference, which can be used to educate and reassure patients and providers.

Underutilization of Acetaminophen in Older Adult Trauma Patients

Introduction Older adults are more vulnerable to opioid-associated morbidity. The purpose of this study was to determine the frequency and timing of acetaminophen and opioid use in the postoperative period. Methods Older adult trauma patients (≥65 years) with hip fractures requiring femur or hip fixation were reviewed (Premier Database 2008-2014). We examined rates of acetaminophen use on the day of surgery and prior to receipt of oral opioids. Mixed-effects linear regression models were used to examine the effects of an acetaminophen-first approach on opioid use the day prior to and on the day of discharge. Results Of the 192 768 patients, 81.6% were Caucasian; 74.0% were female; and the mean age was 82.0 years [± 7.0]. Only 16.8% (32 291) of patients received acetaminophen prior to being prescribed opioids. 27.4% (52 779) received an acetaminophen-opioid combination, and 9.2% (17 730) received opioids without acetaminophen first. Acetaminophen first was associated with reduced opioid use on the day prior to and on the day of discharge (3.52 parenteral morphine equivalent doses (PMEs) less [95% CI: 3.33, 3.70]; P < .0001). A statistically but not clinically significant reduction in length of stay was observed in the acetaminophen-first group. Conclusion Nearly 37% of older adult patients did not receive acetaminophen as first-line analgesia after hip surgery. Multimodal analgesia, including non-opioid medications as first-line, should be encouraged.
