OBJECTIVE: To observe the clinical efficacy of Miao medicinal crossbow acupuncture therapy as adjuvant treatment for lung cancer pain based on oxycodone hydrochloride extended-release tablet. METHODS: A total of 60 patients with lung cancer pain were randomized into an observation group (30 cases, 1 case dropped off) and a control group (30 cases). In the control group, oxycodone hydrochloride extended-release tablet was given orally, 10 mg a time, once every 12 hours. On the basis of the treatment in the control group, Miao medicinal crossbow acupuncture therapy was applied once every other day in the observation group. The treatment of 14 days was required in the two groups. Before and after treatment, the numerical rating scale (NRS) score, number of break-out pain and Karnofsky performance status (KPS) score were observed in the two groups. The equivalent oxycodone consumption and rate of adverse reactions were recorded, the analgesic effect was evaluated in the two groups. RESULTS: Compared before treatment, the NRS scores and number of break-out pain were decreased while the KPS scores were increased after treatment in the two groups (P<0.01). After treatment, the NRS score and number of break-out pain in the observation group were lower than the control group (P<0.01), the KPS score in the observation group was higher than the control group (P<0.05). The equivalent oxycodone consumption of whole course and the rate of adverse reactions i.e. constipation, drowsiness, nausea and vomiting in the observation group were lower than the control group (P<0.05). The analgesic effect rate was 93.1% (27/29) in the observation group, which was superior to 63.3% (19/30) in the control group (P<0.05). CONCLUSION On the basis of oxycodone hydrochloride extended-release tablet, Miao medicinal crossbow acupuncture therapy as adjuvant treatment can effectively relieve the pain degree, reduce the number of break-out pain and improve the health status and quality of life in patients with lung cancer pain, enhance the efficacy of medication and reduce its adverse reactions.

BACKGROUND: Managing acute postoperative pain is challenging for anesthesiologists, surgeons, and patients, leading to adverse events despite making significant progress. Patient-controlled intravenous analgesia (PCIA) is a recommended solution, where oxycodone has depicted unique advantages in recent years. However, controversy still exists in clinical practice and this study aimed to compare two drugs in PCIA. METHODS: We performed a literature search in PubMed, Embase, the Cochrane Central Register of Controlled Trials, Web of Science, Chinese National Knowledge Infrastructure, Wanfang, and VIP databases up to December 2020 to select specific randomized controlled trials (RCTs) comparing the efficacy of oxycodone with sufentanil in PCIA. The analgesic effect was the primary outcome and the secondary outcome included PCIA consumption, the Ramsay sedation scale, patients' satisfaction and side effects. RESULTS: Fifteen RCTs were included in the meta-analysis. Compared with sufentanil, oxycodone showed lower Numerical Rating Scale scores (mean difference [MD] = -0.71, 95% confidence interval [CI]: -1.01 to -0.41; P < 0.001; I2 = 93%), demonstrated better relief from visceral pain (MD = -1.22, 95% CI: -1.58 to -0.85; P < 0.001; I2 = 90%), promoted a deeper sedative level as confirmed by the Ramsay Score (MD = 0.77, 95% CI: 0.35-1.19; P < 0.001; I2 = 97%), and resulted in fewer side effects (odds ratio [OR] = 0.46, 95% CI: 0.35-0.60; P < 0.001; I2 = 11%). There was no statistical difference in the degree of patients' satisfaction (OR = 1.13, 95% CI: 0.88-1.44; P = 0.33; I2 = 72%) and drug consumption (MD = -5.55, 95% CI: -14.18 to 3.08; P = 0.21; I2 = 93%). CONCLUSION: Oxycodone improves postoperative analgesia and causes fewer adverse effects, and could be recommended for PCIA, especially after abdominal surgeries.

OBJECTIVE: To evaluate the clinical effect of filiform fire needling on moderate and severe pain in advanced cancer. METHODS: A total of 66 patients with moderate and severe pain in advanced cancer were randomly divided into an observation group (34 cases, 4 cases dropped off) and a control group (32 cases, 2 cases dropped off). The two groups were treated with oral analgesics continuously for 4 weeks. The moderate pain patients was given bucinnazine hydrochloride tablets (starting at 30 mg, once every 6 hours, increasing by 30%-50% until the titration volume was reached), and the severe pain patients were given oxycodone hydrochloride sustained-release tablets (starting at 20 mg every 12 hours and increasing by 25%-50% until the titration volume was reached). The observation group was cooperated with filiform fire needling at point, Zusanli (ST 36), Liangqiu (ST 34), Qihai (CV 6), Guanyuan(CV 4), Quchi (LI 11) and Waiguan (TE 5) once every other day for 4 weeks. The changes of numerical rating scales (NRS) scores were observed in both groups before and after treatment, and the amount of analgesics and the incidence of adverse reactions were recorded. The clinical effects in the two groups were evaluated. RESULTS: The effective rate was 90.0% (27/30) in the observation group, which was higher than 66.7% (20/30) in the control group (<0.05). After treatment, the NRS scores of both groups were lower than those before treatment (<0.05), and the reducing degree in the observation group was larger than that in the control group (<0.05). The average dosage of bunarizine hydrochloride tablets and oxycodone hydrochloride sustained release tablets to titration volume in the observation group was less than that in the control group (<0.05). The incidence of adverse reactions was 23.3% (28/120) in the observation group, which was lower than 44.2% (53/120) in the control group (<0.05). CONCLUSION Filiform fire needling can alleviate pain symptoms of patients with moderate and severe pain in advanced cancer, reduce the amount of analgesics, and decrease the incidence of adverse reactions.

OBJECTIVE: Oxycodone, a semi-synthetic thebaine derivative opioid, is commonly used for treating moderate to severe pain. The aim of this study was to compare the efficacy and side effects of oxycodone and fentanyl used for treating postoperative pain with intravenous patient-controlled analgesia (IV-PCA) after laparoscopic gynecologic surgery. METHODS: A total of 122 patients were randomized to receive postoperative pain treatment with either oxycodone (n=62, group O) or fentanyl (n=60, group F). Patients received 7.5 mg oxycodone and 150 mcg fentanyl with ketorolac 30 mg at the end of anesthesia, and then continued with IV-PCA (conversion dose ratio, 50:1) for 48 hours postoperatively. A blinded observer assessed postoperative pain based on a numerical rating scale, postoperative nausea and vomiting and other side effects, infused PCA dose, patient satisfaction, and sedation level. RESULTS: No significant differences were observed in patient satisfaction according to the analgesic used during the 48 hours postoperative period. CONCLUSION: Oxycodone showed similar efficacy for pain relief compared to fentanyl when used at a conversion dose ratio of 50:1. Therefore, oxycodone may be useful as an alternative to fentanyl for IV-PCA after laparoscopic gynecologic surgery.

BACKGROUND/AIMS: Opioids cause gastrointestinal (GI) dysmotility, decrease gut secretion, and affect gut sphincters. Symptoms of opioid-induced bowel dysfunction may be alleviated by peripherally acting opioid antagonists like naloxegol, but detailed knowledge on GI effects of this drug is lacking. We hypothesized that naloxegol, compared to placebo, would reduce GI transit time and colonic fecal volume in opioid-treated healthy participants. METHODS: We conducted a randomized, double-blinded, single-center, 2-way cross-over study in 24 healthy males, randomized to a 6 day treatment period of oxycodone (15 mg twice a day) co-administered with either naloxegol (25 mg once a day) or matching placebo. Participants swallowed an electromagnetic capsule which determined GI transit times. Colonic fecal volume was quantified with magnetic resonance imaging both pre-treatment and post-treatment. RESULTS: Naloxegol reduced total GI transit time by 21% (56 hours vs 71 hours, P = 0.02) and colonic transit time by 23% (45 hours vs 59 hours, P < 0.01), compared to placebo. However, no difference in colonic fecal volume was found (818 mL vs 884 mL, P = 0.20). CONCLUSIONS: Short-term administration of naloxegol in healthy participants reverses the retardation of total GI and colonic transit induced by oxycodone. This supports the use of naloxegol in the treatment of GI side effects to opioid treatment, and add knowledge to the current understanding of mechanisms behind peripherally-acting opioid antagonists.

We compared the analgesic profile between patient-controlled analgesia (PCA) using oxycodone and morphine in post total abdominal hysterectomy patients. Eighty-four ASA I or II patients, aged 18 to 65 years who underwent total abdominal hysterectomy were recruited into this prospective, double blind, randomised controlled study. They were randomised to receive either PCA oxycodone 0.7 mg per bolus or PCA morphine 1 mg per bolus for postoperative pain relief. At the end of surgery, all patients received IV morphine 0.1 mg/kg and skin incision was infiltrated with 20 mls of bupivacaine 0.25%. Post-operative pain scores, opioids consumptions, sedation scores and side effects were assessed upon arrival and at 30 minutes after arrival to recovery area, as well as at 6 hours and 24 hours after the operation in the ward. Patients’ overall satisfaction was also assessed 24 hours postoperatively.No significant differences were observed in terms of postoperative pain scores, opioids consumption, sedation scores, side effects as well as patient’s overall satisfaction between the PCA oxycodone and PCA morphine group. Oxycodone was comparable to morphine as PCA in terms of total opioid consumption, pain scores and satisfaction level for patients undergoing total abdominal hysterectomy and therefore may be an alternative to morphine in postoperative pain management as PCA

Background: Intravenous (IV) oxycodone has been used at induction to prevent an intubation reaction. The aims of the current study were to calculate the median effective dose (ED) and the 95% effective dose (ED) of an IV bolus of oxycodone that blunts the hemodynamic response to tracheal intubation with propofol according to gender and to observe the adverse events of induction-dose oxycodone. Methods: Adult patients who required general anesthesia and tracheal intubation were enrolled. Tracheal intubation was performed using unified TD-C-IV video laryngoscopy and an ordinary common endotracheal tube. Dixon's up-and-down method was used to obtain EDdata for women and men separately. The initial dose of oxycodone was 0.2 mg/kg for women and 0.3 mg/kg for men (step size was 0.01 mg/kg). Next, a dose-response curve from the probit analysis was generated to determine the EDand EDto blunt the intubation reaction in female and male patients. Adverse events following oxycodone injection were observed for 5 min before propofol injection. Results: Sixty-three patients were analyzed, including 29 females and 34 males. According to the probit analysis, the ED and EDof oxycodone required to blunt the intubation reaction in women were 0.254 mg/kg (95% confidence interval [CI], 0.220-0.328 mg/kg) and 0.357 mg/kg (95% CI, 0.297-2.563 mg/kg), respectively. In men, the ED and EDwere 0.324 mg/kg (95% CI, 0.274-0.381 mg/kg) and 0.454 mg/kg (95% CI, 0.384-2.862 mg/kg), respectively. Men required 28% more oxycodone than women for induction (P < 0.01). The most common adverse events were dizziness (87.3%), vertigo (66.7%), sedation (74.6%), and respiratory depression (66.7%). Conclusions Oxycodone can be used for induction to prevent intubation reactions. Gender affected the EDand EDof oxycodone for blunting the tracheal intubation reaction.

OBJECTIVE: To investigate the relationship between OPRM1 118A/G gene polymorphism and oxycodone analgesic dose in patients with cancer pain. METHODS: DNA sequencing was used to detect the genotypies of OPRM1 118 A/G site in 203 patients with moderate and severe cancer pain, and to compare the relationship between the pain degree and the dose of oxycodone at 3 and 30 days after treatment in patients with different genotypes. RESULTS: The fequencies of AA, AG and GG genotypes at the OPRM1 118 A/G site were 34.78%, 52.70%, and 12.52%, respectively. The dosage of oxycodone in GG genotype was significantly higher than that in AA genotype and AG genotype (15.44±10.19 vs. 10.25±4.53, 10.49±5.26; 89.15±27.69 vs. 43.59±12.19, 48.27±18.79) on the 3 and 30 day after treatment, difference was statistically significant (P< 0.05). CONCLUSION For cancer pain patients with GG genotype of OPRM1 118A/G site, if they need to achieve the same analgesic effect as patients with AA and AG genotype, the dose of oxycodone should be increased.

PURPOSE: The purpose of this study was to assess the factors influencing the rescue medication decisions for breakthrough cancer patients and evaluate treatments using the factors. METHODS: Based on the results of an online survey conducted by the Korean Society of Hospice and Palliative Care from September 2014 through December 2014, we assessed the level of agreement on nine factors influencing rescue medication preference. The same factors were used to evaluate oral transmucosal fentanyl lozenge, oral oxycodone and intravenous morphine. RESULTS: Agreed by 77 physicians, a rapid onset of action was the most important factor for their decision of rescue medication. Other important factors were easy administration, strong efficacy, predictable efficacy and less adverse effects. Participants agreed that intravenous morphine produced a rapid onset of action and strong and predictable efficacy and cited difficulty of administration and adverse effects as negative factors. Oral oxycodone was desirable in terms of easy administration and less adverse effects. However, its onset of action was slower than intravenous morphine. While many agreed to easy administration of oral transmucosal fentanyl lozenge, the level of agreement was low for strength and predictability of its efficacy, long-term durability and sleep improvement. CONCLUSION: Rapid onset of action is one of the important factors that influence physicians' selection of rescue medication. Physicians' assessment of rescue medication differed by medication.
