Abstract
Enhanced Recovery After Surgery (ERAS) protocols have substantially proven their merit in diminishing recuperation durations and mitigating postoperative adverse events in geriatric populations undergoing colorectal cancer procedures. Despite this, the pivotal aspect of postoperative pain control has not garnered the commensurate attention it deserves. Typically, employing a multimodal analgesia regimen that weaves together nonsteroidal anti-inflammatory drugs, opioids, local anesthetics, and nerve blocks stands paramount in curtailing surgical complications and facilitating reduced convalescence within hospital confines. Nevertheless, this integrative pain strategy is not devoid of pitfalls; the specter of organ dysfunction looms over the geriatric cohort, rooted in the abuse of analgesics or the complex interplay of polypharmacy. Revolutionary research is delving into alternative delivery and release modalities, seeking to allay the inadvertent consequences of analgesia and thereby potentially elevating postoperative outcomes for the elderly post-colorectal cancer surgery populace. This review examines the dual aspects of multimodal analgesia regimens by comparing their established benefits with potential limitations and offers insight into the evolving strategies of drug administration and release.

Patient Controlled Subcutaneous Analgesia of Hydromorphone Versus Morphine to Treat Moderate and Severe Cancer Pain: A Randomized Double-Blind Controlled Trial. J Pain Symptom Manage 2024; 67:50-58. [PMID: 37742793 DOI: 10.1016/j.jpainsymman.2023.09.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 08/17/2023] [Accepted: 09/13/2023] [Indexed: 09/26/2023]
Abstract
CONTEXT Hydromorphone and morphine are the common drugs used for the treatment of moderate to severe cancer pain. Patient controlled subcutaneous analgesia (PCSA) is an effective technique to manage cancer pain. However, few studies have been conducted to show the efficacy and safety of PCSA of hydromorphone for the relief of cancer pain. OBJECTIVES To explore the short-term efficacy and safety of PCSA elicited by hydromorphone for moderate to severe cancer pain. METHODS This was a single-center, randomized, active-controlled, double-blind trial (from April 2019 to August 2021). Sixty patients with moderate to severe cancer pain were randomized (1:1) to hydromorphone or morphine groups according to drug delivery by PCSA. The primary outcome was the pain intensity measured by a numerical rating scale (NRS) at 72 hours. Secondary outcomes included pain intensity measured by NRS at baseline, 15 minutes, 30 minutes, two hours, eight hours, 24 hours and 48 hours. The daily occurrence of breakthrough pain (BTP), impact of pain on quality of life measured by the brief pain inventory (BPI), the daily additional consumption of opioids and the incidence of adverse events were also recorded. Adverse events included nausea, vomiting, dizziness, constipation and respiratory depression. RESULTS A total of 57 patients (28 patients in the hydromorphone group and 29 patients in the morphine group) in the West China Hospital of Sichuan University were investigated. The mean (standard deviation [SD]) NRS in the two groups at baseline was 7.8 (1.7) in the hydromorphone group and 7.6 (1.7) in the morphine group, and at 72 hours were 3.4 (1.8) and 3.2 (1.5), respectively. The postoperative NRS in both groups was decreased significantly compared to baseline. The mean (SD) NRS at 30 minutes in the hydromorphone group was significantly lower than in the morphine group (3.9 [2.6] vs. 5.3 [2.1], P = 0.035). The daily occurrence of BTP in both groups at 48 hours and 72 hours decreased significantly compared to the corresponding baseline (P < 0.05), and there was no significant difference between the two groups. The total scores and sub-item scores of BPI at 24 hours and 72 hours after PCSA in both groups decreased significantly from baseline. A comparison of daily additional consumption of opioids between the two groups revealed no statistically significant difference. There were no significant differences in the incidences of nausea, vomiting, dizziness or constipation between the two groups (P > 0.05). CONCLUSION This study found that the PCSA of both hydromorphone and morphine could effectively and safely relieve short-term moderate to severe cancer pain. Of note, the PCSA of hydromorphone took effect more quickly than that of morphine.

JAMA Netw Open 2023; 6:e2332408. [PMID: 37672272 PMCID: PMC10483316 DOI: 10.1001/jamanetworkopen.2023.32408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 07/30/2023] [Indexed: 09/07/2023] Open
Abstract
Importance A key objective in contemporary surgery is to reduce or eliminate the usage of opioids to minimize gastrointestinal adverse effects, fatigue, and long-term opioid dependency. Objectives To evaluate the association of the implementation of a care bundle of 3 opioid-sparing interventions with the amount of opioids consumed postoperatively among patients undergoing major abdominal surgery and to examine the respective associations of the 3 components. Design, Setting, and Participants This retrospective cohort study was performed at Ersta Hospital, an elective teaching hospital in Stockholm, Sweden. All patients undergoing major colorectal surgery between January 1, 2016, through December 31, 2019, were included. Data analysis was conducted from February 1, 2020, to May 30, 2022. Exposures A care bundle consisting of an individualized opioid regimen, regular gabapentinoids, and clonidine as a rescue analgesic was gradually introduced early in the study period. Main Outcomes and Measures Amount of in-hospital administered intravenous and oral opioids on the day of surgery and the first 5 postoperative days (morphine milligram equivalents [MME]). The association between exposure and outcome was examined using multivariable linear regression. Results Overall, 842 patients had major colorectal surgery in the study period (mean [SD] age, 64.6 [15.5] years; 421 [50%] men). Median (range) opioid usage decreased from 75 (0-796) MME in 2016 to 22 (0-362) MME in 2019 (P < .001), and the proportion of patients receiving 45 MME or less increased from 35% to 66% (P < .001). On multivariable analysis (F5, 836 = 57.5; P < .001), an individualized opioid strategy (β = -11.6; SE = 3.8; P = .003), the use of gabapentin (β = -39.1; SE = 4.5; P < .001), and increasing age (β = -1.0; SE = 0.11; P < .001) were associated with less opioid consumption, while the use of clonidine was associated with more opioid intake (β = 11.6; SE = 3.6; P = .001). Conclusions and Relevance In this cohort study of 842 patients undergoing colorectal surgery, a care bundle consisting of an individualized opioid regimen, regular gabapentin, and clonidine as a rescue analgesic was found to be associated with a significant decrease in opioids consumed postoperatively. Regular gabapentin and an individualized opioid regimen were particularly strongly associated with this decrease and should be further evaluated as components of multimodal, opioid-free postoperative analgesia.

Abstract
Background Spinal anaesthesia as an adjunct to general anaesthesia may reduce postoperative pain and opioid consumption after laparoscopic abdominoperineal rectal amputation. We designed a randomized double blinded pilot study with two objectives: 1) to explore potential benefits of spinal anaesthesia as an adjunct to general anaesthesia and 2) to provide power and sample size estimations for potential differences between the groups. Primary outcome measures were postoperative pain and oral morphine equivalent (OMEq) consumption. Methods Patients scheduled for elective laparoscopic abdominoperineal rectal amputation at the University Hospital of North Norway were randomised to spinal (n=5) or a sham spinal procedure (n=5). Numeric rating scale (NRS) and OMEq were monitored postoperatively for 72 h. Results Age, sex, body mass index, and ASA were not significantly different between the groups. During surgery, patients in the spinal group received less remifentanil (p=0.06). NRS was lower in the spinal group 1 hr after admittance to the post-anaesthesia care unit (PACU) (p=0.06) and on the first postoperative day at 8 AM (p=0.03). OMEq consumption in the PACU was lower in the spinal group (p=0.008), but no differences between the groups were detected after discharge to the ward. Sample size estimations revealed that eight patients in each group would be needed to study potential NRS differences after admission to the PACU and 23 patients in each group to study potential differences in OMEq consumption on day 1. Conclusion Spinal anaesthesia as an adjunct to general anaesthesia reduces postoperative pain and opioid consumption after laparoscopic abdominoperineal rectal amputation. Data from the current study should be followed up by a sufficiently powered randomized controlled trial. Clinical Trial Registration Trial registered at https://clinicaltrials.gov (NCT05406765).

Abstract
BACKGROUND Orthopaedic surgeries are among the most painful procedures. By adding low-dose morphine to intrathecal bupivacaine for spinal anaesthesia, the analgesic effect can be improved. The objeсtive of the study was tо compare the efficacy and safety of lоw-dоse (0.1 mg аnd 0.2 mg) intrаtheсаl mоrphine (ITM). METHODS А prоspeсtive rаndоmised study was соnduсted at the Hоspitаl оf Trаumаtоlоgy аnd Оrthоpaediсs, Riga, Latvia (February 2020 tо May 2021) and enrolled 90 patients undergoing primary hip arthroplasty. All subjects were randomised intо three study grоups, using the online tool оn www.randomiser.org . Treatment groups were allocated to intrathecal morphine (0.1 mg and 0.2 mg) in addition to bupivacaine (15 to 18 mg). The primary outcome was postoperative pain intensity among the three study groups within 24 hours by NRS. The secondary outcomes: pain at rest 4 h, 7 h, 12 h, 24 h postoperatively, respiratory rate, SpО2, morphine соnsumptiоn, оxygen supply, opioid-related аdverse reасtiоns within 24 hours postoperatively. Dаtа were аnаlysed using R version 4.2.0, applying the Mann-Whitney test, Pearson's chi-squared test, Fisher's exact test, Friedman test, Wilcoxon test. RESULTS The primary outcome in the control, ITM 0.1 mg, ITM 0.2 mg groups, respectively: 2.56, 0.87, 0.28 (p < 0.001). The secondary outcomes in the control, ITM 0.1 mg, ITM 0.2 mg group, respectively: pain scores 4h - 1.21, 0.48, 0.17 (p = 0.068); 7 h - 2.62, 1.00, 0.17 (p < 0.001); 12 h - 3.08, 0.65, 0.37 (p < 0.001); 24 h - 2.50, 1.20, 0.41 (p < 0.001); rescue medication requests (incidence, %): 77%, 16.7%, 13.3% (p < 0.001); mean respiratory rate (breath/min) - 15.2; 15.2 (p > 0.05); mean SpO2 (%): 96.7%; 95.7%; 96.07%. Significant adverse effects: pruritus in ITM 0.2 mg group (23% of subjects, p < 0.001). CONCLUSIONS Adult patients undergoing THA under spinal anaesthesia with bupivacaine and 0.2 mg morphine had superior analgesia to patients who received spinal analgesia with bupivacaine or bupivacaine and 0.1 mg morphine.

Abstract
(1) Background: The management of postoperative pain after knee replacement is an important clinical problem. The best results in the treatment of postoperative pain are obtained using multimodal therapy principles. Intrathecal morphine (ITM) and single-shot femoral nerve block (SSFNB) are practiced in the treatment of postoperative pain after knee replacement, with the most optimal methods still under debate. The aim of this study was to compare the analgesic efficacy with special consideration of selected side effects of both methods. (2) Materials and methods: Fifty-two consecutive patients undergoing knee arthroplasty surgery at the Department of Orthopedics and Traumatology of the Medical University of Warsaw were included in the study. Patients were randomly allocated to one of two groups. In the ITM group, 100 micrograms of intrathecal morphine were used, and in the SSFNB group, a femoral nerve block in the distal femoral triangle was used as postoperative analgesia. The other elements of anesthesia and surgery did not differ between the groups. (3) Results: The total dose of morphine administered in the postoperative period and the effectiveness of pain management did not differ significantly between the groups (cumulative median morphine dose in 24 h in the ITM group 31 mg vs. SSFNB group 29 mg). The incidence of nausea and pruritus in the postoperative period differed significantly in favor of patients treated with a femoral nerve block. (4) Conclusions: Although intrathecal administration of morphine is similarly effective in the treatment of pain after knee replacement surgery as a single femoral triangle nerve block, it is associated with a higher incidence of cumbersome side effects, primarily nausea and pruritus.
