Perioperative intravenous lidocaine in thoracoscopic surgery for improved postoperative pain control: a randomized, placebo-controlled, double-blind, superiority trial.

ABSTRACT:

Background

Pain, including associated pain management, remains a burden on patients after thoracic surgery. Our objective was to investigate whether perioperative intravenous administration of lidocaine reduces postoperative morphine consumption and pain intensity after video-assisted thoracoscopic surgery (VATS).

Methods

In this double-blind, placebo-controlled superiority trial, patients undergoing VATS with a planned duration of ≤90 minutes were randomized within an intention-to-treat setting. Patients received either intravenous lidocaine or placebo as a bolus of 1.5 mg/kg 30 minutes before incision, followed by a continuous infusion of 3.0 mg/kg/hour until 2 hours after skin closure. Pain and morphine consumption were evaluated when resting and when coughing 1, 2, 4, 8, 16, 24, and 48 hours after skin closure and in a follow-up 14, 90, and 180 days postoperatively.

Results

Twenty-eight patients were included in the lidocaine group, 24 in the placebo group. Patients' characteristics and preoperative pain scores were similar in both groups. When coughing, patients of the lidocaine group had less pain within 24 hours after skin closure than the placebo group (4.60±1.64 vs. 5.52±1.65; P=0.02). Morphine consumption was not statistically significantly lower in lidocaine group (18.22±12.87 vs. 21.26±9.39 mg; P=0.26). There were no significant differences between groups in secondary outcomes.

Conclusions

Our results suggest that perioperative intravenous lidocaine administration reduces pain scores after VATS. The beneficial clinical effects are limited. Nevertheless, intravenous lidocaine may be helpful as part of a multimodal analgesia protocol or with patients in whom the use of other analgesics is contraindicated.

Project description:BackgroundChronic postoperative pain (CPSP) is one of the common complications of breast cancer patients, which can seriously affect the quality of life and long-term prognosis of patients. The purpose of this study was to investigate whether perioperative intravenous lidocaine infusion could reduce the incidence of CPSP in patients with breast cancer.MethodsFemale patients undergoing radical breast cancer surgery were randomly assigned to the 2% lidocaine group (L) and the control group (S). group L received an intravenous infusion of 1.5 mg/kg lidocaine 10 minutes prior to induction, followed by a continuous infusion of 2 mg/kg/h until the end of surgery. The control group received an equal amount of saline. The primary outcome was the incidence of CPSP at 3 months. Secondary outcomes included VAS pain scores and frequency of remedial analgesia within 24 hours postoperatively; incidence of CPSP at 1 and 6 months; and scores on the Brief Pain Inventory (BPI), Simplified McGill Pain Questionnaire (SF-MPQ), and Neuropathic Pain Score (DN-4) at 1, 3, and 6 months postoperatively.ResultsEighty-two patients participated in this study. A total of 78 patients completed the 3-month postoperative follow-up (39 in group S and 39 in group L). At 3 months, the incidence of CPSP was significantly lower in the L group than in the S group (33.3% in the S group and 12.8% in the L group, P=0.032). Pain scores at rest and during exercise were significantly lower in the L group than in the S group at different time points (P≤0.001 and P<0.001). The need for remedial analgesia at 24 hours postoperatively also differed significantly between the two groups (P=0.036). At 6 months, the incidence of CPSP was also lower in the L group than in the S group (29.7% in the S group and 10.5% in the L group, P=0.038). The differences in SF-MPQ scores were statistically significant at both 3 and 6 months postoperatively (P=0.022, P=0.037).ConclusionsIntravenous infusion of lidocaine reduces the incidence of CPSP in breast cancer patients at 3 and 6 months and is effective in relieving acute postoperative pain.Trial registrationChinese Clinical Trial Registry ChiCTR2100050445.

Project description:IntroductionThe transition of acute to chronic postoperative pain (CPP) remains a significant burden to the rehabilitation of patients. The research for adjuvants to prevent CPP continues; among others, dexmedetomidine and lidocaine seem promising agents.MethodsThis is a long-term follow-up of a randomized, placebo-controlled, double-blind study on women who underwent open abdominal gynecological surgery and received dexmedetomidine or lidocaine or placebo infusion perioperatively (n = 81). The effect of these adjuvants on the development of CPP and neuropathic pain was assessed during a 12-month follow-up. Eighty-one (81) women ASA I-II, aged between 30 and 70 years, were randomly assigned to receive either dexmedetomidine (DEX group) or lidocaine (LIDO group) or placebo (CONTROL group) perioperatively. Before anesthesia induction, all patients received a loading intravenous dose of either 0.6 μg/kg dexmedetomidine or 1.5 mg/kg lidocaine or placebo, followed by 0.6 μg/kg/h dexmedetomidine or 1.5 mg/kg/h lidocaine or placebo until last suture. Patients were followed up to obtain the long-term outcomes at 3, 6, and 12 months. At these time-points, pain intensity was assessed with the Numerical Rating Scale, (NRS: 0-10) and the development of neuropathic elements with the Douleur Neuropathique 4 (DN4) score. Prognostic parameters that could affect chronic pain and its components were also identified.ResultsData from 74 women were analyzed. Dexmedetomidine significantly reduced NRS scores comparing to placebo at 3 months (p = 0.018), while at 6 months, lidocaine was found superior to placebo (p = 0.02), but not to dexmedetomidine, in preventing neuropathic pain (DN4 < 4). Regarding secondary endpoints, higher NRS cough scores at 48 h were associated with statistically significant NRS and DN4 scores at 3, 6, and 12 months (p < 0.02). At 6 months, a statistically significant correlation was also found between higher NRS values and older age (p = 0.020).ConclusionsDexmedetomidine was superior to placebo regarding the duration and severity of CPP, while lidocaine exhibited a protective effect against neuropathic elements of CPP.Trial registrationClinicalTrials.gov identifier, NCT03363425.

Project description:BackgroundThe risk of postoperative cognitive dysfunction(POCD) in laparoscopic surgery should not be overlooked. Intravenous lidocaine can reduce perioperative inflammatory response in patients undergoing laparoscopic surgery, while the effect of intraoperative intravenous lidocaine on postoperative cognitive function in patients undergoing laparoscopic colorectal cancer surgery has not been well studied. We investigated whether intraoperative lidocaine improves postoperative cognitive function after laparoscopic radical resection for colorectal cancer.MethodsWe conducted a prospective, randomized double blinded controlled trial to investigate the effect of intravenous lidocaine on rapid postoperative recovery in patients undergoing laparoscopic radical resection of colorectal cancer. The patients were randomly assigned to receive either intravenous lidocaine or saline. The primary outcome was cognitive dysfunction defined by a decrease from pre- to postoperative ≥ 2 of the Mini-Mental State Examination (MMSE) score, at the 3rd and the 7th postoperative days. Secondary outcomes were the MMSE raw score and parameters of the patients' postoperative recovery such as agitation and length of stay in the post-anaesthesia care unit (PACU), length of hospital stay, markers of inflammation (white blood cell count and CRP), and incidence of complications.ResultsSeventy-three patients in the lidocaine group and 77 patients in the control group completed the trial. The rate of cognitive dysfunction was lower in the lidocaine group than that in the control group, both at the 3rd (18.57% vs. 63.64% for each group respectively; RR = 0.26, 95%CI = 0.19-0.32; p < 0.0001) and at the 7th postoperative day (12.33% vs. 53.25% for each group respectively; RR = 0.28, 95%CI = 0.22-0.35; P < 0.001). The postoperative MMSE scores were also higher in the lidocaine group than in the control group both at the 3rd (median 25 vs. 24 respectively) and at the 7th postoperative day (26 vs. 24 respectively). Also, patients in the lidocaine group displayed a lower white blood cell count than the control group at the 1st postoperative day (8.5 ± 2.7 vs. 10.4 ± 3.3; p < 0. 001). No differences were evidenced for the other secondary outcomes.ConclusionsIntraoperative intravenous lidocaine can significantly improve postoperative cognitive function in patients undergoing laparoscopic radical resection of colorectal cancer.Trial registrationChinese Clinical Trial Registry (16/1/2022, registration number: ChiCTR2200055683).

Project description:Despite the laparoscopic approach becoming the standard in colorectal surgery, postoperative pain management for minimally invasive surgery is still mainly based on strategies that have been established for open surgical procedures. Patient-controlled epidural and intravenous analgesia are considered standard postoperative analgesia regimens in colorectal surgery. Epidural analgesia provides excellent analgesia, but is increasingly scrutinized in laparoscopic surgery since postoperative pain after the laparoscopic approach is significantly reduced. Moreover, epidural analgesia can be associated with numerous complications. Therefore, epidural analgesia is no longer recommended for the management of postoperative pain in laparoscopic colorectal surgery. Likewise, patient-controlled intravenous analgesia is subject to significant side effects. Given these important limitations of the traditional strategies for postoperative analgesia, effective and efficient alternatives in patients undergoing laparoscopic colorectal surgery are needed. Both the transversus abdominis plane block and systemically administered lidocaine have already been reported to effectively reduce pain after laparoscopic colorectal surgery. We hypothesize that the transversus abdominis plane block is superior to perioperative intravenous lidocaine.One hundred and twenty five patients undergoing laparoscopic colorectal surgery will be included in this prospective, randomized, double-blind controlled clinical trial. Patients will be randomly allocated to three different postoperative strategies: postoperative patient-controlled intravenous analgesia with morphine (control group, n = 25), a transversus abdominis plane block with ropivacaine 0.375% at the end of surgery plus postoperative patient-controlled intravenous analgesia with morphine (TAP group, n = 50), or perioperative intravenous lidocaine plus postoperative patient-controlled intravenous analgesia with morphine (LIDO group, n = 50). As the primary outcome parameter, we will evaluate the opioid consumption during the first 24 postoperative hours. Secondary endpoints include the Numeric Rating Scale, time to return of intestinal function, time to mobilization, inflammatory response, incidence of postoperative nausea and vomiting, length of hospital stay and postoperative morbidity as assessed with the Clavien-Dindo classification.Recognizing the importance of a multimodal approach for perioperative pain management, we aim to investigate whether a transversus abdominis plane block delivers superior pain control in comparison to perioperative intravenous lidocaine and patient-controlled intravenous analgesia with morphine alone.EudraCT Identifier: 2014-001499-73; 31 July 2014.

Project description:BackgroundExperimental evidence has indicated the benefits of statins for the treatment of postoperative delirium. Previously, clinical trials did not reach definite conclusions on the effects of statins on delirium. Some clinical trials have indicated that statins reduce postoperative delirium and improve outcomes, while some studies have reported negative results.AimTo evaluate whether perioperative rosuvastatin treatment reduces the incidence of delirium and improves clinical outcomes.MethodsThis randomized, double-blind, and placebo-controlled trial was conducted in a single center in Jiangsu, China. This study enrolled patients aged greater than 60 years who received general anesthesia during elective operations and provided informed consent. A computer-generated randomization sequence (in a 1:1 ratio) was used to randomly assign patients to receive either rosuvastatin (40 mg/d) or placebo. Participants, care providers, and investigators were all masked to group assignments. The primary endpoint was the incidence of delirium, which was assessed twice daily with the Confusion Assessment Method during the first 7 postoperative days. Analyses were performed on intention-to-treat and safety populations.ResultsBetween January 1, 2017 and January 1, 2020, 3512 patients were assessed. A total of 821 patients were randomly assigned to receive either placebo (n = 411) or rosuvastatin (n = 410). The incidence of postoperative delirium was significantly lower in the rosuvastatin group [23 (5.6%) of 410 patients] than in the placebo group {42 (13.5%) of 411 patients [odds ratios (OR) = 0.522, 95% confidence interval (CI): 0.308-0.885; P < 0.05]}. No significant difference in 30-d all-cause mortality (6.1% vs 8.7%, OR = 0.67, 95%CI: 0.39-1.2, P = 0.147) was observed between the two groups. Rosuvastatin decreased the hospitalization time (13.8 ± 2.5 vs 14.2 ± 2.8, P = 0.03) and hospitalization expenses (9.3 ± 2.5 vs 9.8 ± 2.9, P = 0.007). No significant differences in abnormal liver enzymes (9.0% vs 7.1%, OR = 1.307, 95%CI: 0.787-2.169, P = 0.30) or rhabdomyolysis (0.73% vs 0.24%, OR = 3.020, 95%CI: 0.31-29.2, P = 0.37) were observed between the two groups.ConclusionThe current study suggests that perioperative rosuvastatin treatment reduces the incidence of delirium after an elective operation under general anesthesia. However, the evidence does not reveal that rosuvastatin improves clinical outcomes. The therapy is safe. Further investigation is necessary to fully understand the potential usefulness of rosuvastatin in elderly patients.
