Analgesic Effects of Intravenous Acetaminophen vs Placebo for Endoscopic Sinus Surgery and Postoperative Pain: A Randomized Clinical Trial

Oral versus intravenous acetaminophen for perioperative pain management in adult patients undergoing non-cardiac surgery: A quantile segmented regression analysis

STUDY OBJECTIVE

Determine whether preferential use of perioperative enteral acetaminophen is associated with changes in perioperative pain, narcotic administration, or time to meeting criteria for post anesthesia care unit (PACU) discharge, compared to preferential parenteral administration.

DESIGN

Retrospective Cohort with quantile segmented regression analysis. Groups determined by date of surgery, one year pre-initiative and one year post-initiative.

SETTING

Operating room and PACU of a tertiary academic medical center.

PATIENTS

Adult (age > 18 years), ASA status 1-5, non-pregnant patients undergoing non-cardiac surgery of less than six hours duration admitted to the PACU postoperatively.

INTERVENTIONS

A multidisciplinary initiative to preferentially utilize enteral over parenteral acetaminophen.

MEASUREMENTS

The primary outcome was narcotic consumption in the PACU. Secondary outcomes were intraoperative narcotic administration, pain score on PACU admission and discharge, and time to meeting criteria for PACU discharge.

RESULTS

24,701 patients were included in the analysis; 12,379 had surgery prior to the initiative and 12,322 after. Enteral acetaminophen administration increased preoperatively from 13.49% to 26.84%, and postoperatively from 43.16% to 51.45%, while intraoperative parenteral APAP use dropped from 43.23% to 6.81%. Quantile Segmented regression analysis after adjusting for period (pre versus postintervention), day, age, gender, inpatient status, and ASA class demonstrated a decrease in adjusted median perioperative acetaminophen dose (-175 mg P < 0.001), with no significant difference in level change of intraoperative or PACU narcotic administration. There was no significant difference in median time to meet criteria for PACU discharge, though there was a significant change in the slope, (-0.36, p = 0.007.) Median pain scores measured on a standard 0-10 numeric rating scale at PACU admission did not change, while median pain scores at PACU discharge decreased slightly (-0.24 p < 0.001). There was no change in the probability of PONV.

CONCLUSION

In adult patients undergoing non-cardiac surgery of <6 h duration, preferential use of enteral rather than parenteral acetaminophen is associated with non-inferior outcomes in narcotic requirements, pain scores, time to PACU discharge, and probability of PONV when compared with routine parenteral administration. Further studies are needed to validate these findings.

Evaluation of efficacy and safety of subcutaneous acetaminophen in geriatrics and palliative care (APAPSUBQ)

INTRODUCTION

Subcutaneous infusion (SC) or hypodermoclysis is an old perfusion technique that is often used off-label although it has been shown to be effective. Acetaminophen (paracetamol) subcutaneous injection is performed in some centers despite the lack of conclusive evidence on its effectiveness. This study aims to evaluate the efficacy of subcutaneous infusion of Acetaminophen in the treatment of pain and fever in geriatrics and in palliative care and to determine its safety profile and possible side effects.

MATERIAL AND METHODS

This experimental study was conducted between 2018 and 2019 on adult patients in palliative care or in geriatrics in several hospitals and nursing homes in Lebanon. Primary outcomes were change in temperature; change in pain score on the numerical rating scale (NS) or on the Algoplus scale after 60 min from the start of the infusion; and the appearance of local side effects at the infusion site. Changes in the various parameters at 30 min and 180 min were also evaluated as secondary outcomes.

RESULTS

Thirty-one patients were included in the study, with a total of 120 doses of acetaminophen. At 60 min, the mean decrease in pain on the NS was 5.35 points, while the mean decrease in temperature was 0.79 degrees Celsius. At 60 min, 75%, CI = [47.62-92.73] of the patients who received acetaminophen for pain and 66.67%, CI = [38.38-88.17] of those who received it for fever had clinically significant improvement. The overall effect of subcutaneous acetaminophen, defined as any clinically significant effect on pain or fever, was 70.97%, CI = [51.96-85.78]. The overall effect at 30 min and at 180 min was 23.33%, CI = [9.93-42.28] and 87.10%, CI = [70.17-96.37], respectively. The side effects reported 30 min after the injection and observed after at least one of the doses were: local edema in 16 patients (51.61%), induration in one patient (3.23%), local pain in one patient (3.23%) and local heat in one patient (3.23%). At 180 min, only 2 patients (6.45%) still had edema at the infusion site.

CONCLUSION

Subcutaneous administration of acetaminophen is effective and well tolerated in geriatric and palliative care patients. It is appropriate when no other route is available, especially for home-based care. Comparative studies are needed to allow the expansion of this practice.

Assessment of Opioid Use and Analgesic Requirements After Endoscopic Sinus Surgery: A Randomized Clinical Trial

Importance

The opioid epidemic has generated interest in optimizing opioid prescribing after common surgeries. Recent studies have shown a broad range of analgesic prescription patterns following endoscopic sinus surgery (ESS).

Objective

To compare the efficacy of different analgesic regimens after ESS.

Design, Setting, and Participants

This multi-institutional, nonblinded randomized clinical trial was conducted at 6 tertiary centers across the US and Canada and included participants who underwent ESS for acute or chronic rhinosinusitis. The study was conducted from March 2019 to March 2020, and the data were analyzed in November to December 2020.

Interventions

All participants received acetaminophen, 650 mg, as the first-line analgesic. From there, patients were randomized to either oxycodone rescue (oxycodone, 5 mg, as second-line therapy) or ibuprofen rescue (ibuprofen, 600 mg, as second-line therapy, with oxycodone, 5 mg, reserved for breakthrough pain).

Main Outcomes and Measures

Baseline characteristics and disease severity were collected at enrollment. Medication logs, pain scores, and epistaxis measures were collected until postoperative day 7. The primary outcome was the postoperative visual analog scale score for pain. Brief Pain Inventory Pain Severity and Pain Interference Scores were also collected.

Results

A total of 118 patients were randomized (62 [52.5%] oxycodone rescue, 56 [47.5%] ibuprofen rescue; mean [SD] age, 46.7 [16.3] years; 44 women [44.0%]; 83 White [83.0%], 7 Black [7.0%], and 7 Asian individuals [7.0%]). After exclusions for loss to follow-up and noncompliance, 51 remained in the oxycodone rescue group and 49 in the ibuprofen rescue group. The groups had similar demographic characteristics and disease severity. Thirty-two (63%) in the oxycodone rescue group had adequate pain management with acetaminophen only, while 19 (37%) consumed at least 1 oxycodone dose. In the ibuprofen rescue group, 18 (16%) required only acetaminophen, 28 (57%) used only acetaminophen and ibuprofen, and the remaining 13 (26%) consumed 1 or more oxycodone doses. The groups had similar average acetaminophen (9.69 vs 7.96 doses; difference, 1.73; 95% CI, -1.37 to 4.83) and oxycodone (1.89 vs 0.77 doses; difference, 1.13; 95% CI, -0.11 to 2.36) use. Both groups had similar postoperative visual analog scale scores. A subanalysis that compared opioids users with nonusers showed clinically significant lower pain scores in nonusers at multiple postoperative points.

Conclusions and Relevance

In this randomized clinical trial, most patients who underwent ESS could be treated postoperatively using a nonopioid regimen of either acetaminophen alone or acetaminophen and ibuprofen. Ibuprofen as a second-line therapy did not reduce overall narcotic consumption, but the overall narcotic use was low in both groups.

Perioperative Opioid Administration

Opioids form an important component of general anesthesia and perioperative analgesia. Discharge opioid prescriptions are identified as a contributor for persistent opioid use and diversion. In parallel, there is increased enthusiasm to advocate opioid-free strategies, which include a combination of known analgesics and adjuvants, many of which are in the form of continuous infusions. This article critically reviews perioperative opioid use, especially in view of opioid-sparing versus opioid-free strategies. The data indicate that opioid-free strategies, however noble in their cause, do not fully acknowledge the limitations and gaps within the existing evidence and clinical practice considerations. Moreover, they do not allow analgesic titration based on patient needs; are unclear about optimal components and their role in different surgical settings and perioperative phases; and do not serve to decrease the risk of persistent opioid use, thereby distracting us from optimizing pain and minimizing realistic long-term harms.

The efficacy of sphenopalatine ganglion block for pain management after endoscopic sinus surgery: a meta-analysis of randomized controlled studies

INTRODUCTION

The efficacy of sphenopalatine ganglion (SPG) block for pain control after endoscopic sinus surgery remains controversial. We conduct a systematic review and meta-analysis to explore the influence of SPG block on pain intensity after endoscopic sinus surgery.

METHODS

We search PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases through June 2019 for randomized controlled trials (RCTs) assessing the efficacy of SPG block for pain management after endoscopic sinus surgery. This meta-analysis is performed using the random-effect model.

RESULTS

Six RCTs are included in the meta-analysis. Overall, compared with control group for endoscopic sinus surgery, SPG block is associated with the decrease in pain scores at 6 h (Std. MD =  - 0.71; 95% CI =  - 1.08 to - 0.34; P = 0.0002) and 24 h (Std. MD =  - 0.51; 95% CI =  - 0.87 to - 0.14; P = 0.006), the number of rescue analgesics (RR = 0.26; 95% CI = 0.16 to 0.42; P < 0.00001) and incidence of nausea and vomiting (RR = 0.52; 95% CI = 0.30-0.89; P = 0.02), but demonstrate no obvious impact on pain scores at 2 h (Std. MD =  - 0.99; 95% CI =  - 2.80-0.83; P = 0.29) or headache (RR = 1.30; 95% CI = 0.38-4.46; P = 0.67).

CONCLUSIONS

SPG block can provide additional benefits for pain management after endoscopic sinus surgery.

Perioperative Analgesia for Sinus and Skull-Base Surgery

Perioperative analgesic management is multifaceted, and an individualized approach should be taken with each patient. Preoperative discussion of the plan for pain control and the patient's postoperative expectations is a necessary facet for optimal outcomes of analgesia. There is the potential for significant abuse and development of dependence on opioids. Nonopioids, such as nonsteroidal anti-inflammatory drugs, acetaminophen, and gabapentinoids, provide reliable alternatives for analgesic management following sinus and skull-base surgery. There is a paucity of literature regarding perioperative pain regimens for sinus and skull-base surgery, and the authors hope that this review serves as a valuable tool for otolaryngologists.

Effect of Intravenous Acetaminophen on Postoperative Hypoxemia After Abdominal Surgery: The FACTOR Randomized Clinical Trial

IMPORTANCE

Opioid-induced ventilatory depression and hypoxemia is common, severe, and often unrecognized in postoperative patients. To the extent that nonopioid analgesics reduce opioid consumption, they may decrease postoperative hypoxemia.

OBJECTIVE

To test the hypothesis that duration of hypoxemia is less in patients given intravenous acetaminophen than those given placebo.

DESIGN, SETTING, AND PARTICIPANTS

Randomized, placebo-controlled, double-blind trial conducted at 2 US academic hospitals among 570 patients who were undergoing abdominal surgery, enrolled from February 2015 through October 2018 and followed up until February 2019.

INTERVENTIONS

Participants were randomized to receive either intravenous acetaminophen, 1 g (n = 289), or normal saline placebo (n = 291) starting at the beginning of surgery and repeated every 6 hours until 48 postoperative hours or hospital discharge, whichever occurred first.

MAIN OUTCOMES AND MEASURES

The primary outcome was the total duration of hypoxemia (hemoglobin oxygen saturation [Spo2] <90%) per hour, with oxygen saturation measured continuously for 48 postoperative hours. Secondary outcomes were postoperative opioid consumption, pain (0- 10-point scale; 0: no pain; 10: the most pain imaginable), nausea and vomiting, sedation, minimal alveolar concentration of volatile anesthetic, fatigue, active time, and respiratory function.

RESULTS

Among 580 patients randomized (mean age, 49 years; 48% women), 570 (98%) completed the trial. The primary outcome, median duration with Spo2 of less than 90%, was 0.7 (interquartile range [IQR], 0.1-5.1) minutes per hour among patients in the acetaminophen group and 1.1 (IQR, 0.1-6.6) minutes per hour among patients in the placebo group (P = .29), with an estimated median difference of -0.04 (95% CI,-0.18 to 0.11) minutes per hour. None of the 8 secondary end points differed significantly between the acetaminophen and placebo groups. Mean pain scores within initial 48 postoperative hours were 4.2 (SD, 1.8) in the acetaminophen group and 4.4 (SD, 1.8) in the placebo group (difference, -0.28; 95% CI, -0.71 to 0.15); median opioid use in morphine equivalents was 50 mg (IQR, 18-122 mg) and 58 mg (IQR, 24-151 mg) , respectively, with a ratio of geometric means of 0.86 (95% CI, 0.61-1.21).

CONCLUSIONS AND RELEVANCE

Among patients who underwent abdominal surgery, use of postoperative intravenous acetaminophen, compared with placebo, did not significantly reduce the duration of postoperative hypoxemia over 48 hours. The study findings do not support the use of intravenous acetaminophen for this purpose.

Nonopioid Adjuncts and Alternatives

Multimodality nonopioid analgesia can be effective for pain control. Balancing risks and benefits of treatment should guide the appropriateness of opioid versus nonopioid pain control.

Anesthesia Management and Postanesthetic Recovery Following Endoscopic Sinus Surgery

OBJECTIVES

Delayed anesthesia recovery following endoscopic sinus surgery (ESS) can be an indicator of immediate complications and negatively impact healthcare efficiency. This study aims to examine clinical factors with a focus on improving clinical practice.

METHODS

Medical records of patients undergoing ESS under general anesthesia from 2014 to 2018 were reviewed. Based on the interquartile range of anesthesia recovery for the cohort, patients in the upper quartile were categorized as "prolonged" and the lowest three quartiles as "goal" recovery. Patient and surgical characteristics were investigated.

RESULTS

Analyzing 416 patients who underwent ESS, the median anesthesia recovery time was 48 [35-66] minutes. Prolonged recovery was associated with higher body mass index (odds ratio 1.50 [95% confidence interval 1.03-2.18] per 10 kg/m² , P = .03) and surgical duration (1.37 [1.10-1.72] per hour, P < .01). Inversely, goal recovery was associated with preoperative acetaminophen (0.61 [0.38-0.98], P = .04) and intraoperative remifentanil (0.55 [0.32-0.93], P = .03). Patients with prolonged recovery had higher rates of severe pain (33 (31.7%) vs. 25 (8.0%), P < .01), respiratory depression (7 [6.7] vs. 2 [0.6], P < .01), oversedation (39 [37.5] vs. 39 [12.5], P < .01), and the need for rescue opioids (52 [50] vs. 71 [22.8], P < .01). In addition to reduced postanesthesia recovery time, patients who were administered preemptive acetaminophen had lower rates of severe pain (OR 0.55 [0.31-0.98], P = .04) and nausea and vomiting (0.39 [0.17-0.87], P = .02).

CONCLUSION

Our findings substantiate the use of acetaminophen and remifentanil in ESS, facilitating anesthesia recovery. Broadly consideration of preemptive acetaminophen could further increase postoperative comfort in ESS.

Opioid prescribing patterns and usage after rhinologic surgery: A systematic review

OBJECTIVE

Judicious management of analgesics following rhinologic surgery is important for curtailing over-prescription of opioids. Limited data exists defining expected pain levels and appropriate opioid requirements after rhinologic surgery.

METHODS

A systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PubMed, Embase, Ovid MEDLINE, Cochrane Library databases were queried, and relevant articles were identified.

RESULTS

A total of 405 articles were identified, of which 13 met final inclusion criteria. Significant heterogeneity existed regarding type and quantity of opioid medication prescribed. Eight studies utilized a subjective patient-reported pain score as an outcome measure and reported mild to moderate postoperative pain that diminished over the first 3-6 days. Eight studies reported over-prescription of opioid medications with inappropriate storage of excess pills at home. Several factors were associated with an increased opioid requirement, including concurrent septoplasty, younger age, and current smoking status.

CONCLUSION

Rhinologic surgery is well tolerated with mild to moderate, short-lived postoperative pain. A limited amount and duration of opioid medications is required for routine management. Patients are frequently prescribed more opioids than is necessary for expected pain level, resulting in the potential for opioid misuse, abuse, and diversion. Current evidence is limited by a predominance of level 4 studies. Larger, higher quality studies with standardized reporting of pain score and opioid prescription quantity are needed.

Intravenous vs oral acetaminophen in sinus surgery: A randomized clinical trial

BACKGROUND

Multimodal perioperative analgesia including acetaminophen is recommended by current guidelines. The comparative efficacy of intravenous vs oral acetaminophen in sinus surgery is unknown. We aimed to determine whether intravenous or oral acetaminophen results in superior postoperative analgesia following sinus surgery.

METHODS

This was a prospective randomized trial with blinded endpoint assessments conducted at a single large academic medical center. Subjects undergoing functional endoscopic sinus surgery were randomized to intravenous vs oral acetaminophen in addition to standard anesthetic and surgical care. The primary outcome was visual analogue scale pain score at 1 hour postoperatively.

RESULTS

One hundred and ten adult patients were randomized; 9 were excluded from the data analysis. Fifty patients were assigned to intravenous acetaminophen and 51 to oral acetaminophen. Postoperative pain scores at 1 hour (primary endpoint) were not significantly different between the intravenous and oral acetaminophen groups. Similarly, there was no significant difference in pain scores at 24 hours postoperatively. Finally, there was no significant difference in postoperative opioid usage in the postanesthesia care unit or over the first 24 hours postoperatively.

CONCLUSIONS

This is the first comparative efficacy trial of oral vs intravenous acetaminophen in sinus surgery. There was no significant difference in pain scores at 1 or 24 hours postoperatively, and no difference in postoperative opioid use. Intravenous acetaminophen offers no apparent advantage over oral acetaminophen in patients undergoing sinus surgery.

Patterns in Pain and Opiate Use after Endoscopic Sinus Surgery

OBJECTIVE

To evaluate postoperative opiate use and patients' opinions regarding pain management after endoscopic sinus surgery (ESS).

STUDY DESIGN

Case series with planned data collection.

SETTING

Tertiary referral medical center.

SUBJECTS AND METHODS

We prospectively evaluated postoperative opiate utilization in adults undergoing ESS over a 2-year period at an academic medical facility. Exclusion criteria included use of nasal packing, intracranial or orbital procedures, tumor surgery, and any use of endoscopic drills. All patients underwent bilateral maxillary antrostomy, total ethmoidectomy, sphenoidotomy, and frontal sinusotomy with or without septoplasty. Patients were discharged with 30 oxycodone-acetaminophen (5-325 mg) and a survey assessing pain and narcotic/nonnarcotic use on postoperative days 0 to 7.

RESULTS

A total of 64 patients completed surveys. Mean ± SD narcotic use over the 7-day postoperative period was 7.7 ± 7.6 pills. Patients with high narcotic use (>6 pills total) had no differences in demographic or surgical factors from those with low use (≤6 pills) but did report a higher level of postoperative day 1 pain (4.8 ± 1.1 vs 2.0 ± 1.4, P < .001). Narcotic use declined during this period, with <30% of patients requiring narcotics by postoperative day 3.

CONCLUSION

Our results support reduced opiate prescription and encouragement of nonnarcotic use after ESS without compromising effective pain management.

Effect of Over the Counter Ibuprofen Dosing after Sinus Surgery for Chronic Rhinosinusitis: A Prospective Cohort Pilot Study

Introduction:

Management of pain following endoscopic sinus surgery (ESS) often involves intermittent use of opioid medications. Given the current opioid crisis, many surgeons aim to minimize opioid prescriptions. However, surgeons often avoid the use of NSAIDs following ESS out of concern for increased bleeding risk. We sought to evaluate the effectiveness and safety of over the counter dosing of ibuprofen on pain and bleeding rates following ESS.

Methods:

Prospective cohort pilot study of patients undergoing ESS. Patients self-selected either control arm (acetaminophen and PRN oxycodone) or intervention arm (alternating ibuprofen with acetaminophen, and PRN oxycodone). Outcome measures included pain (10-point visual analog scale [VAS]), bleeding rate (10-point VAS), and number of opiate pills consumed.

Results:

Thirty-nine patients completed the study (15 control and 24 intervention). Overall, patients in the intervention arm reported decreased pain levels at days 1 (−0.9 [95%CI: −2.2, 0.5], 3 (−0.9 [95%CI: −2.3, 0.5]), and 7 (−0.6 [95%CI: −1.8, 0.6]), as well as decreased postoperative bleeding at those same days −0.9 [95%CI: −2.1, 0.4], −0.9 [95%CI: −2.1, 0.4], and −0.7 [95% CI: −1.2, −0.7], compared to controls. Opiate consumption was similar between groups with patients consuming on average four opiate pills (oxycodone 5 mg).

Conclusions:

Over the counter dosing of ibuprofen along with acetaminophen may yield better pain control after sinus surgery compared to acetaminophen alone. Additionally, there was no significant difference in epistaxis in the ibuprofen cohort compared to the cohort who did not take ibuprofen. Furthermore, this study showed very few opioid pills were consumed after routine ESS regardless of pain regimen prescribed. A larger trial is needed to make definitive statements on safety and efficacy.

Predictive value of SNOT-22 on additional opiate prescriptions after endoscopic sinus surgery

BACKGROUND

Endoscopic sinus surgery (ESS) is generally well tolerated, yet a subset of patients require an additional opiate prescription in the postoperative period. The purpose of this study was to quantify differences in both preoperative and immediate postoperative 22-item Sino-Nasal Outcome Test (SNOT-22) scores between patients with a single prescription and those requiring additional opiate prescriptions (AOPs).

METHODS

Patients undergoing ESS between November 2016 and August 2017 were reviewed retrospectively. The Medical and Controlled Substance Utilization Review and Evaluation System (CURES) records were reviewed; patients requiring AOP within 60 days after surgery were identified. The primary and secondary outcomes of interest were the association of baseline and first postoperative visit SNOT-22 total and domain scores with AOP.

RESULTS

A total of 121 patients were reviewed, 22 (18.2%) required AOP. Baseline SNOT-22 scores were higher in aggregate (58.7 ± 16.0 vs 46.1 ± 22.5) and ear/facial domain (11.4 ± 4.8 vs 8.5 ± 5.4) in the AOP group (p < 0.01). AOP patients also demonstrated higher scores across all SNOT-22 domains (p < 0.001) at the immediate preoperative visit. There was no difference in the absolute improvement between groups (15.5 ± 18.30 vs 12.3 ± 23.9, p = 0.54). AOP patients experienced less relative improvement (20.2% vs 34.8%, p < 0.05) and smaller mean effect size (0.57 vs 0.70, p < 0.001) after ESS.

CONCLUSION

Patients reporting increased ear and facial symptoms at baseline have an increased risk of additional opiate prescription after surgery; preoperative SNOT-22 scores may provide utility in identifying these patients. Subjects in both cohorts report symptomatic improvement after ESS; however, relative, not absolute, improvement in SNOT-22 scores is more predictive of AOP.

Perioperative analgesia for patients undergoing endoscopic sinus surgery: an evidence-based review

BACKGROUND

Misuse and diversion of prescription opioids have been critical in facilitating the opioid epidemic. Our objective was to perform a systematic evidence-based review delineating perioperative regimens (including opioid alternatives) evaluated for endoscopic sinus surgery.

METHODS

PubMed/MEDLINE, Cochrane Library, and EmBase databases were evaluated for studies detailing analgesics employed after endoscopic sinus surgery. Studies were assessed for level of evidence. Bias risk was evaluated using the Cochrane Bias tool and GRADE criteria. Medication, administration, adverse effects, pain scores, and rescue analgesic consumption were evaluated. A summary of evidence detailing benefits, harm, and cost was prepared.

RESULTS

Thirty-two studies encompassing 1812 patients were included. The GRADE criteria determined the overall evidence to be of moderate quality. Perioperative acetaminophen had few adverse events and reduced immediate need for opioid rescue after sinus surgery; studies evaluating acetaminophen demonstrate a preponderance of benefit over harm. Nonsteroidal anti-inflammatory drugs (NSAIDs) also reduce postoperative opioid consumption, although a small portion of patients undergoing sinus surgery harbor the potential for NSAID intolerance. The aggregate level of evidence for studies evaluating NSAIDs was grade A, whereas the aggregate grade of evidence for several other agents was grade B.

CONCLUSION

There is evidence supporting the use of NSAIDs and gabapentin for the control of pain after endoscopic sinus surgery. Acetaminophen, α-agonists, and local anesthetics are also viable options for postoperative analgesia. Familiarity with these data is essential to facilitate the use of opioid alternatives. Further large-scale, multi-institutional, randomized trials are needed to provide conclusive recommendations for these perioperative analgesics.
