Postoperative recovery of colorectal patients enhanced with dexmedetomidine (PReCEDex): a systematic review and meta-analysis of randomized controlled trials. Surg Endosc 2024:10.1007/s00464-024-11060-x. [PMID: 39060623 DOI: 10.1007/s00464-024-11060-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 07/06/2024] [Indexed: 07/28/2024]
Abstract
BACKGROUND Intraoperative administration of dexmedetomidine has shown promise in improving postoperative gastrointestinal function. In the context of colorectal surgery, the results remain inconsistent. This review aims to provide a synthesis of studies assessing the effect of dexmedetomidine on postoperative gastrointestinal function in colorectal surgery patients. METHODS CENTRAL, Emcare, Embase, and MEDLINE were searched up to September 2023. Randomized controlled trials involving adult patients (≥ 18 years) undergoing elective colorectal surgery, comparing dexmedetomidine administration to a control group, and reporting on postoperative gastrointestinal function were included. Non-comparative and emergent procedures were excluded. Primary outcome was time to first flatus or bowel movement, and secondary outcomes included length of stay and time to solid oral intake. Risk of bias was assessed using the Cochrane risk of bias tool for randomized studies. RESULTS After screening 1194 citations, eight studies were included. Studies comprised of 570 patients in the dexmedetomidine group (mean age: 65.8 years, 43% female, mean BMI: 22.7 kg/m2) and 556 patients in control group (mean age 70.6 years, 40% female, mean BMI 22.5 kg/m2). Dexmedetomidine administration resulted in a shorter time to flatus (MD -4.55 h, 95% CI: 20.14-8.95, p < 0.005, very low certainty of evidence), a shorter time to first bowel movement (MD -11.9 h, 95% CI: 18.74-5.05, p < 0.005, very low certainty of evidence), a shorter time to solid oral intake (MD -4.34 h, 95% CI: 17.43-11.24, p < 0.005, moderate certainty of evidence), and a shorter length of stay (MD -.06 days, 95% CI: 1.99-0.12, p < 0.05, very low certainty of evidence). CONCLUSION In adult patients undergoing elective colorectal surgery, intraoperative use of dexmedetomidine results in clinically meaningful improvements in postoperative gastrointestinal function and consequently, shorter length of stay. Therefore, dexmedetomidine may serve as a valuable adjunct in enhancing postoperative recovery of patients following elective colorectal surgery, thereby reducing healthcare utilization, and improving patient outcomes.

Abstract
BACKGROUND Postoperative paralytic ileus (POI) is a significant concern following gastrointestinal tumor surgery. Effective preventive and therapeutic strategies are crucial but remain elusive. Current evidence from randomized-controlled trials on pharmacological interventions for prevention or treatment of POI are systematically reviewed to guide clinical practice and future research. MATERIALS AND METHODS Literature was systematically searched for prospective randomized-controlled trials testing pharmacological interventions for prevention or treatment of POI after gastrointestinal tumor surgery. Meta-analysis was performed using a random effects model to determine risk ratios and mean differences with 95% CI. Risk of bias and evidence quality were assessed. RESULTS Results from 55 studies, involving 5078 patients who received experimental interventions, indicate that approaches of opioid-sparing analgesia, peripheral opioid antagonism, reduction of sympathetic hyperreactivity, and early use of laxatives effectively prevent POI. Perioperative oral Alvimopan or intravenous administration of Lidocaine or Dexmedetomidine, while safe regarding cardio-pulmonary complications, demonstrated effectiveness concerning various aspects of postoperative bowel recovery [Lidocaine: -5.97 (-7.20 to -4.74)h, P <0.0001; Dexmedetomidine: -13.00 (-24.87 to -1.14)h, P =0.03 for time to first defecation; Alvimopan: -15.33 (-21.22 to -9.44)h, P <0.0001 for time to GI-2 ] and length of hospitalization [Lidocaine: -0.67 (-1.24 to -0.09)d, P =0.02; Dexmedetomidine: -1.28 (-1.96 to -0.60)d, P =0.0002; Alvimopan: -0.58 (-0.84 to -0.32)d, P <0.0001] across wide ranges of evidence quality. Perioperative nonopioid analgesic use showed efficacy concerning bowel recovery as well as length of hospitalization [-1.29 (-1.95 to -0.62)d, P =0.0001]. Laxatives showed efficacy regarding bowel movements, but not food tolerance and hospitalization. Evidence supporting pharmacological treatment for clinically evident POI is limited. Results from one single study suggest that Neostigmine reduces time to flatus and accelerates bowel movements [-37.06 (-40.26 to -33.87)h, P <0.0001 and -42.97 (-47.60 to -38.35)h, P <0.0001, respectively] with low evidence quality. CONCLUSION Current evidence concerning pharmacological prevention and treatment of POI following gastrointestinal tumor surgery is limited. Opioid-sparing concepts, reduction of sympathetic hyperreactivity, and laxatives should be implemented into multimodal perioperative approaches.

Effect of intraoperative dexmedetomidine on recovery of gastrointestinal function after caesarean section undergoing spinal and epidural anesthesia: A randomized, double blind, placebo-controlled clinical trial. Eur J Obstet Gynecol Reprod Biol 2024; 297:30-35. [PMID: 38574697 DOI: 10.1016/j.ejogrb.2024.03.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 03/12/2024] [Accepted: 03/26/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE Gastrointestinal dysfunction after cesarean section negatively affects postoperative recovery. Dexmedetomidine has been shown to improve postoperative gastrointestinal function in patients undergoing lumbar spinal fusion surgery and laparoscopic gastrectomy, but its role in cesarean section has not been fully elucidated. The study aimed to investigate the effect of dexmedetomidine on gastrointestinal function after cesarean section. STUDY DESIGN 220 pregnant women who underwent elective cesarean section were randomized into group D and group S. Group D patients received a loading dose of 0.5 μg/kg of dexmedetomidine for 10 mins followed by a maintenance dose of 0.5 μg/kg/h intravenously immediately after the umbilical cord was cut intraoperatively, whereas the other group (group S) received an equivalent quantity of normal saline as loading and maintenance dose IV by infusion pump. The primary outcome was time to first flatus after surgery (hours). Secondary outcomes included time to first feces and first bowel sounds (hours), incidence rates of postoperative gastrointestinal complications, and the length of postoperative hospital stay (days). RESULTS Modified intention-to-treat analysis showed that patients in Group D had a significantly shorter time to first flatus (21 [16 to 28.25] vs. 25 [18 to 32.25] h; P = 0.014), time to first feces (45.5 [35.75 to 55.25] vs. 53 [40 to 60] h; P = 0.019), and time to first bowel sounds (P = 0.010), a lower incidence of abdominal distension (21[20.6 %] vs. 36[34.3 %], P = 0.027), shorter length of postoperative hospital stay (P = 0.010) compared to patients in Group S. CONCLUSION Intraoperative dexmedetomidine infusion reduces the time to first flatus, the incidence of abdominal distension, and shortens the length of hospital stay, promoting gastrointestinal function after cesarean section.

Abstract
BACKGROUND Postoperative pain after cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is important. It appears essential to reduce postoperative pain and morphine consumption. METHODS Retrospective study in a university hospital comparing patient benefiting from CRS-HIPEC under opioid-free anesthesia (OFA; dexmedetomidine) to those anesthetized with opioid anesthesia (OA; remifentanil) using a propensity score matching method. The main objective was the impact of OFA on postoperative morphine consumption in the first 24 h after surgery. RESULTS 102 patients were included, matching on the propensity score allowed selecting 34 unique pairs analyzed. Morphine consumption was lower in the OFA group than in the OA group (3.0 [0.00-11.0] mg/24 h vs. 13.0 [2.5-25.0] mg/24 h; p = 0.02). In multivariable analysis, OFA was associated with a reduction of 7.2 [0.5-13.9] mg of postoperative morphine (p = 0.04). The rate of renal failure with a KDIGO-score > 1 was lower in the OFA group than in the OA group (12% vs. 38%; p = 0.01). There was no difference between groups concerning length of surgery/anesthesia, norepinephrine infusion, volume of fluid therapy, post-operative complications, rehospitalization or ICU readmission within 90 days, mortality, and postoperative rehabilitation. CONCLUSION Our results suggest that OFA for CRS-HIPEC patients appears safe and is associated with less postoperative morphine use and acute kidney injury.

Abstract
BACKGROUND Postoperative ileus (POI) is a complication that may occur after abdominal or nonabdominal surgery. Intravenous dexmedetomidine (Dex) has been reported to accelerate postoperative gastrointestinal function recovery; however, updated evidence is required to confirm its robustness. METHODS To identify randomized controlled trials examining the effects of perioperative intravenous Dex on gastrointestinal function recovery in patients undergoing noncardiac surgery, databases including MEDLINE, EMBASE, Google Scholar, and Cochrane Library were searched on August 2023. The primary outcome was time to first flatus. Secondary outcomes included time to oral intake and defecation as well as postoperative pain scores, postoperative nausea/vomiting (PONV), risk of hemodynamic instability, and length of hospital stay (LOS). To confirm its robustness, subgroup analyses and trial sequential analysis were performed. RESULTS The meta-analysis of 22 randomized controlled trials with 2566 patients showed that Dex significantly reduced the time to flatus [mean difference (MD):-7.19 h, P <0.00001), time to oral intake (MD: -6.44 h, P =0.001), time to defecation (MD:-13.84 h, P =0.008), LOS (MD:-1.08 days, P <0.0001), and PONV risk (risk ratio: 0.61, P <0.00001) without differences in hemodynamic stability and pain severity compared with the control group. Trial sequential analysis supported sufficient evidence favoring Dex for accelerating bowel function. Subgroup analyses confirmed the positive impact of Dex on the time to flatus across different surgical categories and sexes. However, this benefit has not been observed in studies conducted in regions outside China. CONCLUSIONS Perioperative intravenous Dex may enhance postoperative gastrointestinal function recovery and reduce LOS, thereby validating its use in patients for whom postoperative ileus is a significant concern.

Abstract
Background Different approaches to the prevention of postoperative ileus have been evaluated in numerous randomized controlled trials. This network meta-analysis aimed to investigate the relative effectiveness of different interventions in preventing postoperative ileus. Methods Randomized controlled trials (RCTS) on the prevention of postoperative ileus were screened from Chinese and foreign medical databases and compared. STATA software was used for network meta-analysis using the frequency method. Random-effects network meta-analysis was also used to compare all schemes directly and indirectly. Results A total of 105 randomized controlled trials with 18,840 participants were included in this report. The results of the network meta-analysis showed that intravenous analgesia was most effective in preventing the incidence of postoperative ileus, the surface under the cumulative ranking curve (SUCRA) is 90.5. The most effective intervention for reducing the first postoperative exhaust time was postoperative abdominal mechanical massage (SUCRA: 97.3), and the most effective intervention for reducing the first postoperative defecation time was high-dose opioid antagonists (SUCRA: 84.3). Additionally, the most effective intervention for reducing the time to initiate a normal diet after surgery was accelerated rehabilitation (SUCRA: 85.4). A comprehensive analysis demonstrated the effectiveness and prominence of oral opioid antagonists and electroacupuncture (EA) combined with gum. Conclusion This network meta-analysis determined that oral opioid antagonists and EA combined with chewing gum are the most effective treatments and optimal interventions for reducing the incidence of postoperative ileus. However, methods such as abdominal mechanical massage and coffee require further high-quality research.

Abstract
Opioids and benzodiazepines have historically been employed for pain relief; however, they are associated with detrimental long-term neurodevelopmental consequences. Dexmedetomidine, a highly selective alpha-2-adrenoreceptor agonist, has piqued interest as a viable alternative for neonates, owing to its potential analgesic and neuroprotective attributes. We conducted a systematic review to assess the efficacy and safety of dexmedetomidine utilization in neonates. We conducted a comprehensive search of Ovid, MEDLINE, EMBASE, PubMed, Cochrane, and CINAHL, spanning from January 2010 to September 2022. Our review encompassed six studies involving 252 neonates. Overall, dexmedetomidine may be effective in achieving sedation and analgesia. Furthermore, it may reduce the need for adjunctive sedation or analgesia, shorten the time to extubation, decrease the duration of mechanical ventilation, and accelerate the attainment of full enteral feeds. Notably, no significant adverse effects associated with dexmedetomidine were reported. Nevertheless, additional well-designed studies to establish both the efficacy and safety of dexmedetomidine in neonatal care are needed.

Evaluation of the Relationship between Baseline Autonomic Tone and Haemodynamic Effects of Dexmedetomidine. Pharmaceuticals (Basel) 2023; 16:ph16030354.

Abstract
Dexmedetomidine, a central α-2 agonist, is used for procedural sedation and for conscious sedation influences on heart rate and blood pressure. Authors verified whether it is possible to predict bradycardia and hypotension with the use of heart rate variability (HRV) analysis for an autonomic nervous system (ANS) activity assessment. The study included adult patients of both sexes with an ASA score of I or II scheduled for ophthalmic surgery to be performed under sedation. The loading dose of dexmedetomidine was followed by a 15 min infusion of the maintenance dose. The frequency domain heart rate variability parameters from the 5-min Holter electrocardiogram recordings before dexmedetomidine administration were used for the analysis. The statistical analysis also included pre-drug heart rate and blood pressure as well as patient age and sex. The data from 62 patients were analysed. There was no relationship between the decrease in heart rate (42% of cases) and initial HRV parameters, haemodynamic parameters or sex and age of patients. In multivariate analysis, the only risk factor for a decrease in mean arterial pressure (MAP) > 15% from the pre-drug value (39% of cases) was the systolic blood pressure before dexmedetomidine administration as well as for a >15% decrease in MAP sustained at more than one consecutive time point (27% of cases). The initial condition of the ANS did not correlate with the incidence of bradycardia or hypotension; HRV analysis was not helpful in predicting the abovementioned side effects of dexmedetomidine.

The effects of dexmedetomidine for patient-controlled analgesia on postoperative sleep quality and gastrointestinal motility function after surgery: A prospective, randomized, double-blind, and controlled trial. Front Pharmacol 2022; 13:990358. [PMID: 36299885 PMCID: PMC9588938 DOI: 10.3389/fphar.2022.990358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2022] [Accepted: 09/26/2022] [Indexed: 11/25/2022] Open
Abstract
Background: Postoperative poor sleep quality and decreased gastrointestinal motility function are common clinical problems. This study investigated the effects of dexmedetomidine (DEX) combined with sufentanil for patient-controlled analgesia (PCA) on postoperative sleep quality and gastrointestinal motility function after surgery in patients with colorectal cancer. Methods: Patients undergoing colorectal cancer surgery were randomly divided into three groups, DEX 0, 200, or 400 μg, each combined with sufentanil 150 μg for PCA immediately after surgery. The primary outcome was sleep quality in the first 7 days after surgery based on the Athens Insomnia Scale (AIS) score. The secondary outcome was postoperative gastrointestinal motility recovery evaluated by the time of first flatus, first feces and first diet. Postoperative pain intensity, side effects and the length of postoperative hospital stay were also compared among groups. The study was registered with the Chinese Clinical Trial Registry (https://www.chictr.org.cn/enIndex.aspx, ChiCTR2000032601). Results: Ultimately, 210 cases were included. Sleep quality was better in the DEX 200 μg group and DEX 400 μg group than in the DEX 0 μg group. Overall, in the DEX 200 μg group and DEX 400 μg group, the AIS score (p < 0.05) and the incidence of sleep disturbance (7.3%, 4.5% vs. 19.6%, p < 0.001) were lower than those in the DEX 0 μg group in the first 7 days after surgery. There were no significant differences in postoperative gastrointestinal motility among the three groups in the total surgical categories (p > 0.05). In the laparoscopic surgery patients of each group, the time of postoperative first flatus (p = 0.02) and first feces (p = 0.01) was significantly longer in the DEX 400 μg group than in the DEX 0 μg group. There were no differences in postoperative pain intensity, side effects or length of postoperative hospital stay (p > 0.05). Conclusion: The continuous infusion of DEX (200 or 400 μg) for PCA significantly improved postoperative sleep quality after colorectal cancer surgery. DEX (200 μg) was better at improving postoperative sleep quality without affecting gastrointestinal motility function than DEX (400 μg) in patients who underwent laparoscopic colorectal cancer surgery.

Bacillus coagulans TBC169 probiotics for the recovery of intestinal function after gynecological laparoscopic surgery: a randomized, placebo-controlled trial. Int J Clin Pharm 2022; 44:1287-1295. [PMID: 35882823 DOI: 10.1007/s11096-022-01451-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 06/22/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Evidence suggests that Bacillus coagulans TBC169 can improve intestinal motility. AIM To investigate the effectiveness and safety of Bacillus coagulans TBC169 probiotics in promoting the recovery of intestinal function after gynecological laparoscopic surgery. METHOD Patients who underwent laparoscopic surgeries due to gynecological diseases were randomly assigned to the high-dose, conventional-dose, and the placebo-control groups (1:1:1 ratio). The primary outcome was the time to the first passage of flatus time (FFT). Secondary outcomes were the time to the first defecation (FDT), the time to the first bowel sounds (TFBS), the duration of hospital stay (DHS), and the incidence of postoperative adverse events (AEs). RESULTS Compared to the placebo-control group, shorter FFT values were observed in the conventional-dose (23.15 h vs. 29.10 h, P < 0.05) and high-dose (19.15 h vs. 29.10 h, P < 0.001) groups. Similar trends were observed regarding TFBS in the conventional-dose (18.50 h vs. 21.10 h, P < 0.05) and high-dose (15.20 h vs. 21.10 h, P < 0.001) groups. There were no significant differences in FFT and TFBS between the intervention groups. Compared to the placebo-control group, lower incidences of postoperative adverse events were observed in the conventional-dose (12.50% vs. 40.00%, P < 0.05) and the high-dose (5.00% vs. 40.00%, P < 0.001) groups. However, there were no significant differences between these intervention groups. CONCLUSION Bacillus coagulans TBC169 probiotics can accelerate intestinal function recovery, and reduce postoperative adverse events in patients after gynecological laparoscopic surgery. The study protocol was registered at the Chinese Clinical Trial Registry (ChiCTR2200059518).

Abstract
The rapid recovery of gastrointestinal transit is critical for clinical recovery following laparoscopic procedures, including gynecological laparoscopies (GLs). Rehabilitation interventions post-surgery may provide significant prevention against early post-operative gastrointestinal motility disorders and maid aid in the acceleration of post-operative recovery in patients undergoing GLs. Among others, low-frequency electrical stimulation (LFES) has been demonstrated to pronouncedly mitigate the symptoms caused by gastrointestinal motility disorders; thus, this has attracted increasing attention over the past decade. The present study aimed to present an overview of the efficacy and application of LFES in gastrointestinal motility recovery following GL procedures.

Abstract
Dexmedetomidine is a preferred agent for light sedation with minimal adverse effects. We report a case of acute colonic pseudo-obstruction following dexmedetomidine use in a patient with alcohol withdrawal. He was treated with benzodiazepines first to control the withdrawal symptoms, then escalated to dexmedetomidine once delirium tremens ensued. Later on, the patient developed abdominal distension and vomiting. Imaging showed dilated bowel loops and absence of peristalsis on ultrasound. Decompression with the nasogastric (NG) tube was done, with high output from the NG tube. Dexmedetomidine infusion was used twice, and once it was stopped, the NG tube output was reduced, with the resumption of gastrointestinal motility and improvement of the abdominal distension. Recent similar reports of functional intestinal obstruction following alpha-2 (α2) agonist use necessitate further studies of intestinal motility following dexmedetomidine use and awareness of the possible side effect of dexmedetomidine on intestinal motility.

Evaluation of lignocaine, dexmedetomidine, lignocaine-dexmedetomidine infusion on pain and quality of recovery for robotic abdominal hysterectomy: a prospective randomized controlled trial. Braz J Anesthesiol 2021; 72:593-598. [PMID: 34848312 PMCID: PMC9515666 DOI: 10.1016/j.bjane.2021.10.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 10/22/2021] [Accepted: 10/30/2021] [Indexed: 12/22/2022] Open
Abstract
Background: Acute postoperative pain is associated with poor quality of recovery after surgery. Perioperative use of intravenous lignocaine or dexmedetomidine have demonstrated better pain control, early return of bowel function, and effects on quality of recovery. Methods: Ninety-six women planned for elective robotic abdominal hysterectomy were randomized into four groups. Groups received lignocaine infusion (1.5 mg.kg−1 loading, 2 mg.kg−1.h−1 infusion) (Group I), dexmedetomidine infusion (1 µg.kg−1 loading, 0.6 µg.kg−1.h−1 infusion) (Group 2), lidocaine (1.5 mg.kg−1 loading, 2 mg.kg−1.h−1 infusion), and dexmedetomidine infusions (1 µg.kg−1 loading, 0.5 µg.kg−1.h−1 infusion) (Group 3), and normal saline 10 mL loading, 1 mL.kg−1.h−1 infusion) (Group 4). Primary outcome was visual analogue pain scores at 1, 2, 4, 12, and 24 hours after surgery. Secondary outcomes included postoperative fentanyl requirement, time of return of bowel sounds and flatus, QoR15 score on day 1, 2, and discharge. Results: The VAS was significantly lower in Groups 2 and 3 compared to Groups 1 and 4. Total postoperative fentanyl consumption in the first 24 hours was 256.25 ± 16.36 mcg (Group 1), 177.71 ± 16.81 mcg (Group 2), 114.17 ± 16.19 mcg (Group 3), and 304.42 ± 31.26 mcg (Group 4), respectively. Time to return of bowel sounds and passage of flatus was significantly shorter in Groups 2 and 3 (p < 0.01). QoR15 scores after surgery were higher in Group 3 compared to Groups 1, 2, and 4, (p < 0.01) respectively. Conclusion: Combined infusion of lignocaine and dexmedetomidine significantly decreased postoperative pain, fentanyl consumption, and improved quality of recovery score after surgery in patients undergoing Robotic abdominal hysterectomy.

Abstract
IMPORTANCE Postoperative ileus is common after abdominal surgery, and small clinical studies have reported that intraoperative administration of dexmedetomidine may be associated with improvements in postoperative gastrointestinal function. However, findings have been inconsistent and study samples have been small. Further examination of the effects of intraoperative dexmedetomidine on postoperative gastrointestinal function is needed. OBJECTIVE To evaluate the effects of intraoperative intravenous dexmedetomidine vs placebo on postoperative gastrointestinal function among older patients undergoing abdominal surgery. DESIGN, SETTING, AND PARTICIPANTS This multicenter, double-blind, placebo-controlled randomized clinical trial was conducted at the First Affiliated Hospital of Anhui Medical University in Hefei, China (lead site), and 12 other tertiary hospitals in Anhui Province, China. A total of 808 participants aged 60 years or older who were scheduled to receive abdominal surgery with an expected surgical duration of 1 to 6 hours were enrolled. The study was conducted from August 21, 2018, to December 9, 2019. INTERVENTIONS Dexmedetomidine infusion (a loading dose of 0.5 μg/kg over 15 minutes followed by a maintenance dose of 0.2 μg/kg per hour) or placebo infusion (normal saline) during surgery. MAIN OUTCOMES AND MEASURES The primary outcome was time to first flatus. Secondary outcomes were postoperative gastrointestinal function measured by the I-FEED (intake, feeling nauseated, emesis, physical examination, and duration of symptoms) scoring system, time to first feces, time to first oral feeding, incidence of delirium, pain scores, sleep quality, postoperative nausea and vomiting, hospital costs, and hospital length of stay. RESULTS Among 808 patients enrolled, 404 were randomized to receive intraoperative dexmedetomidine, and 404 were randomized to receive placebo. In total, 133 patients (60 in the dexmedetomidine group and 73 in the placebo group) were excluded because of protocol deviations, and 675 patients (344 in the dexmedetomidine group and 331 in the placebo group; mean [SD] age, 70.2 [6.1] years; 445 men [65.9%]) were included in the per-protocol analysis. The dexmedetomidine group had a significantly shorter time to first flatus (median, 65 hours [IQR, 48-78 hours] vs 78 hours [62-93 hours], respectively; P < .001), time to first feces (median, 85 hours [IQR, 68-115 hours] vs 98 hours [IQR, 74-121 hours]; P = .001), and hospital length of stay (median, 13 days [IQR, 10-17 days] vs 15 days [IQR, 11-18 days]; P = .005) than the control group. Postoperative gastrointestinal function (as measured by the I-FEED score) and delirium incidence were similar in the dexmedetomidine and control groups (eg, 248 patients [72.1%] vs 254 patients [76.7%], respectively, had I-FEED scores indicating normal postoperative gastrointestinal function; 18 patients [5.2%] vs 12 patients [3.6%] had delirium on postoperative day 3). CONCLUSIONS AND RELEVANCE In this randomized clinical trial, the administration of intraoperative dexmedetomidine reduced the time to first flatus, time to first feces, and length of stay after abdominal surgery. These results suggest that this therapy may be a viable strategy to enhance postoperative recovery of gastrointestinal function among older adults.

Abstract
INTRODUCTION Dexmedetomidine has opioid sparing actions but its effect on bowel recovery is controversial. Primary aim of this review was to evaluate the effect of perioperative dexmedetomidine on postoperative bowel recovery. Secondary aim was to evaluate the effect of dexmedetomidine on hospital discharge. EVIDENCE ACQUISITION Randomised controlled trials in English language reporting any or all of the following parameters of bowel recovery; time to first bowel sounds, first flatus, first faeces, or time to oral diet were included. EVIDENCE SYNTHESIS Twelve hundred and thirty-five patients from 13 studies were analysed. There were insufficient studies evaluating bowel sounds. Perioperative dexmedetomidine usage significantly reduced the time to first flatus [MD -5.61 hours (95% CI -8.61 to -2.60); P = 0.0003; I2 = 95%], first faeces [MD -12.70 hours (95% CI -19.11 to -6.29); P = 0.0001; I2 = 76%] and the composite outcome of bowel recovery (flatus, faeces, oral diet) [MD -7.44 hours (95% CI -10.31 to -4.57); P < 0.00001; I2 = 96%]. No difference was seen in the time to oral diet [MD -6.29 hours (95% CI -13.48 to 0.91); P = 0.09; I2 = 88%] or hospital discharge [MD -0.47 days (95% CI -1.27 to 0.33); P = 0.25; I2 = 86%]. CONCLUSIONS Perioperative dexmedetomidine usage significantly shortens the time to first flatus, faeces and composite bowel recovery but does not result in a shorter time to oral diet or earlier hospital discharge in adult patients receiving general anaesthesia. Strength of evidence is however very low for the effect of dexmedetomidine on bowel recovery.

Abstract
BACKGROUND Open living donor hepatectomy (OLDH) is a highly painful procedure. Advanced strategies for enhancing perioperative analgesia and accelerating recovery are needed for patients undergoing OLDH. This study evaluated the effects of intravenous infusion of dexmedetomidine (DEX) during OLDH on postoperative analgesia and recovery. METHODS This prospective, randomised, double-blinded, and placebo-controlled study included 34 patients randomised to a control group (group C) and a DEX group (group D). Utilisation of intravenous patient-controlled analgesia (IV-PCA) pump, pain intensity, and postoperative recovery variables were recorded. Moreover, intraoperative anaesthetic consumption, hemodynamic parameters, and fluid status were also recorded. RESULTS During the first 24 hours after surgery, patients in group D had a lower pain intensity. The cumulative numbers of IV-PCA pump presses and fentanyl consumption within 24 and 48 hours postoperatively in group C were significantly higher than in group D. The time to first IV-PCA attempt was prolonged in group D. In addition, faster flatus passage was observed in group D. Intraoperatively, fewer anaesthetic agents were required in group D. Less fluctuation in hemodynamics and reduced bleeding were also found in group D. CONCLUSIONS The present study revealed that the addition of intravenous infusion of DEX during OLDH provided several benefits in relieving postoperative pain and promoting recovery. Therefore, we concluded that intraoperative DEX infusion may play an important role in enhancing the recovery of patients undergoing OLDH.

Abstract
BACKGROUND Acute colonic pseudo-obstruction (ACPO) or Ogilvie's syndrome occurs in 0.22%-7% of patients undergoing surgery, with a mortality of up to 46%. ACPO increased median hospital days versus control in spinal surgery (14 vs. 6 days; P < 0.001). If defined as postoperative ileus, the incidence was 7%-13.4%. Postoperative ileus is associated with 2.9 additional hospital days and an $80,000 increase in cost per patient. We present a case of ACPO in an adult patient undergoing spinal fusion for correction of scoliosis and review the available literature to outline clinical characteristics and surgical outcomes. CASE DESCRIPTION The patient was a 31-year-old woman with untreated advanced scoliosis with no history of neurologic issues. T2-L3 spinal instrumentation and fusion was completed. Plain abdominal radiography showed of dilated cecum 11 cm and the department of general surgery was consulted. Neostigmine administration was planned after conservative treatment failure after transfer to the intensive care unit. The patient was discharged home with no recurrence >60 days. Thirty cases were found in our literature review using PubMed and Embase databases and summarized. CONCLUSIONS Of 30 cases reviewed, only 3 cases of ACPO were specific to patients undergoing spinal fusion for scoliosis. According to the literature, 20% of patients had resolution with conservative treatment, 40% with neostigmine, and 30% with surgical intervention. Other noninvasive treatments may have similar efficacy in preventing complications leading to surgical invention. Sixty clinical trials and 9 systematic reviews were summarized with an updated management algorithm.

Abstract
Background: Dexmedetomidine possesses sedative, sympatholytic, and opioid-sparing properties, but its impact on postoperative gastrointestinal function is controversial. Methods: This single-center, prospective, randomized study compared low-dose dexmedetomidine and placebo on gastrointestinal function recovery and inflammation after posterior lumbar spinal fusion. Sixty-six patients were randomized into two groups and received normal saline (control group) or dexmedetomidine (DEX group) during posterior lumbar fusion. Blood was taken at five timepoints to measure lipopolysaccharides, tumor necrosis factor-α, and C-reactive protein. The primary outcome was duration to first flatus. The secondary outcomes were inflammatory mediators and determination of correlations between perioperative factors and duration to first flatus. Results: Patients in DEX group showed significantly lower duration to first flatus (15.37 [13.35-17.38] vs 19.58 [17.31-21.86] h; p = 0.006) and overall sufentanil consumption (67.19 [63.78-70.62] vs 74.67 [69.96-79.30] μg; p = 0.011) than controls. Lipopolysaccharides, tumor necrosis factor-α, and C-reactive protein did not differ between the groups at any timepoint (all p > 0.05). Multiple linear regression modeling assessed the ability of independent variables to predict variance in duration to first flatus (adjusted R2 = 0.379, p = 0.000). In the model, age (β = 0.243, p = 0.003), gender (β = -3.718, p = 0.011), BMI (β = -0.913, p = 0.001), operative segments (β = -4.079, p = 0.028), and overall sufentanil consumption (β = 0.426, p = 0.000) contributed significantly. Conclusions: Thus, low-dose dexmedetomidine accelerates gastrointestinal function recovery after lumbar spinal fusion. The effect may be partially produced by opioid-sparing effects rather than inhibition of inflammation. Clinical Trial Registration: www.chictr.org.cn, identifier ChiCTR1800018127.

Abstract
BACKGROUND Dexmedetomidine has been shown to have an analgesic effect. However, no consensus was reached in previous studies. METHODS Electronic databases such as PubMed, Embase, and Cochrane Central were searched for relevant randomized controlled trials. The relative risk and weighted mean difference (WMD) were used to analyze the outcomes. Random-effects model was used for meta-analysis. RESULTS Compared with the normal saline group, patients using DEX showed a significantly decreased pain intensity within 6 hours [WMD=-0.93; 95% confidence interval (CI), -1.34 to -0.53) and at 24 hours after surgery (WMD=-0.47; 95% CI, -0.83 to -0.11). DEX usage significantly reduced the cumulative opioids consumption at 24 hours after surgery (WMD=-6.76; 95% CI, -10.16 to -3.35), decreased the rescue opioids consumption in postanesthesia care unit (WMD=-3.11; 95% CI, -5.20 to -1.03), reduced the risk of rescue analgesics (relative risk=0.49; 95% CI, 0.33-0.71), and the interval to first rescue analgesia was prolonged (WMD=34.93; 95% CI, 20.27-49.59). CONCLUSIONS Intravenous DEX effectively relieved the pain intensity, extended the pain-free period, and decreased the consumption of opioids during postoperative recovery of adults in general anesthesia.

Abstract
Post-operative ileus is common after abdominal surgeries. Children undergoing liver transplant are at increased risk of ileus for various reasons including multiple abdominal procedures and use of narcotic medications. Ileus can lead to abdominal compartment syndrome and compromise the integrity of the liver graft. In some of these patients, ileus is resistant to standard therapies including stool softeners, bowel stimulants, enemas, and even methylnaltrexone. Neostigmine has been shown in pediatric case series to be efficacious in some children for refractory post-operative ileus. We report three children (9 months, 3 years, and 12 years old) who developed refractory ileus after liver transplant, with one of them developing abdominal compartment syndrome, who were treated successfully with continuous infusions of neostigmine. Clinical responses included passage of flatus and stool and improvement in abdominal distension. All patients tolerated the infusion without serious adverse effects such as bradycardia or bronchospasm. Neostigmine was used safely in our patients and may be safe and efficacious for the treatment of refractory ileus in pediatric patients after liver transplantation. Neostigmine should be considered early in the treatment of these patients.

Abstract
Background Postoperative pain is one of the most common symptoms after surgery, which brings physical discomfort to patients. In addition, it may cause a series of complications, and even affect the long-term quality of life. The purpose of this prospective, randomized, double-blinded, controlled trial is to investigate the efficacy and safety of dexmedetomidine combined with sufentanil to attenuate postoperative pain in patients after laparoscopic nephrectomy. Methods Ninety patients undergoing laparoscopic nephrectomy were randomized into three groups: the control (sufentanil 0.02 μg/kg/h, Group C), sufentanil plus low dose of dexmedetomidine (0.02 μg/kg/h each, Group D1), and sufentanil plus high dose of dexmedetomidine (0.04 μg/kg/h, Group D2). The patient-controlled analgesia was programmed to deliver a bolus dose of 0.5 ml, followed by an infusion of 2 ml/h and a lockout time of 10 min. The primary goal was to calculate the cumulative amount of self-administered sufentanil; the secondary goals were to estimate pain intensity using the numerical rating scale (NRS), level of sedation, the first bowel movement, concerning adverse effects as well as duration of postoperative hospital stay. Results The total consumption of sufentanil in group D1 and D2 were significantly lower than in group C during the first 8 h after surgery (P < 0.05), whereas there were no statistically significant differences (P > 0.05) between group D1 and D2. Compared with group C, the NRS scores at rest during first 8 h after surgery were significantly lower in group D1 (P < 0.05). The NRS scores, neither at rest nor with movement, show statistically significant differences between group D1 and D2 at each time point following surgery (P > 0.05). The time to first flatus was shorter in group D1 compared with the control group (P < 0.05). In addition, compared with group C, group D1 and D2 had a shorter time for first defecation (P < 0.05). Conclusions Dexmedetomidine combined with sufentanil showed better postoperative analgesia without adverse effects, as well as facilitated bowel movements for patients undergoing laparoscopic nephrectomy. Trial registration We registered this study in a Chinese Clinical Trial Registry (ChiCTR) centre on Dec 23 2015 and received the registration number: ChiCTR-IPR-15007628.

Abstract
AIM To analyze the effect of dexmedetomidine assisted anesthesia on perioperative hemodynamics, anesthetic dosage, and postoperative sedation and analgesia in patients undergoing radical gastrectomy.
METHODS Sixty patients who underwent radical gastrectomy under general anesthesia at Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology from January 2016 to December 2017 were included. The patients were randomly divided into an experimental group and a control group, with 30 patients in each group. In the experimental group, dexmedetomidine infusion was used, while the control group was given equal amount of saline infusion. Hemodynamics, anesthetic dosage, epinephrine norepinephrine and parathyroid hormone levels, and sedative and analgesic effects were compared between the two groups of patients before injection (T0), before induction of anesthesia (T1), before intubation (T2), immediately after intubation (T3), 3 min after intubation (T4), immediately after extubation (T5), and 3 min after extubation (T6).
RESULTS The BIS value of the observation group at T1 was significantly lower than that at T0 group and that of the control group (76.3 ± 3.9 vs 94.1 ± 2.8, P < 0.05). At T1, T3, and T5, the MAP and HR of the control group were significantly higher than those of the observation group (P < 0.05). At T3 and T5, the concentrations of E and NE in the control group were significantly higher than those at T2 and those of the observation group (P < 0.05), although the changes in the observation group were not significant (P > 0.05). At 1 and 4 h after surgery, the VAS scores in the observation group were significantly lower than those in the control group (1.3 ± 0.6 vs 2.6 ± 1.1, 1.6 ± 0.6 vs 2.1 ± 1.8, P < 0.05), and the Ramsay scores in the observation group were significantly higher than those in the control group (3.4 ± 1.0 vs 1.8 ± 0.8, 2.6 ± 0.6 vs 1.9 ± 0.7, P < 0.05). The doses of propofol (1421.6 ± 328.6) and remifentanil (5.3 ± 1.3) in the control group were significantly higher than those in the observation group (1009.8 ± 209.4 and 3.2 ± 1.2, respectively; P < 0.05).
CONCLUSION Dexmedetomidine assisted anesthesia can effectively reduce the fluctuation of hemodynamic parameters and the kinetics of epinephrine and norepinephrine, decrease the amount of narcotic drugs used, reduce postoperative discomfort and pain, and provide good sedation in patients undergoing radical gastrectomy.

Abstract
BACKGROUND The surgical stress response plays an important role on the pathogenesis of perioperative cardiac complications. Alpha-2 adrenergic agonists attenuate this response and may help prevent postoperative cardiac complications. OBJECTIVES To determine the efficacy and safety of α-2 adrenergic agonists for reducing mortality and cardiac complications in adults undergoing cardiac surgery and non-cardiac surgery. SEARCH METHODS We searched CENTRAL (2017, Issue 4), MEDLINE (1950 to April Week 4, 2017), Embase (1980 to May 2017), the Science Citation Index, clinical trial registries, and reference lists of included articles. SELECTION CRITERIA We included randomized controlled trials that compared α-2 adrenergic agonists (i.e. clonidine, dexmedetomidine or mivazerol) against placebo or non-α-2 adrenergic agonists. Included trials had to evaluate the efficacy and safety of α-2 adrenergic agonists for preventing perioperative mortality or cardiac complications (or both), or measure one or more relevant outcomes (i.e. death, myocardial infarction, heart failure, acute stroke, supraventricular tachyarrhythmia and myocardial ischaemia). DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality, extracted data and independently performed computer entry of abstracted data. We contacted study authors for additional information. Adverse event data were gathered from the trials. We evaluated included studies using the Cochrane 'Risk of bias' tool, and the quality of the evidence underlying pooled treatment effects using GRADE methodology. Given the clinical heterogeneity between cardiac and non-cardiac surgery, we analysed these subgroups separately. We expressed treatment effects as pooled risk ratios (RR) with 95% confidence intervals (CI). MAIN RESULTS We included 47 trials with 17,039 participants. Of these studies, 24 trials only included participants undergoing cardiac surgery, 23 only included participants undergoing non-cardiac surgery and eight only included participants undergoing vascular surgery. The α-2 adrenergic agonist studied was clonidine in 21 trials, dexmedetomidine in 24 trials and mivazerol in two trials.In non-cardiac surgery, there was high quality evidence that α-2 adrenergic agonists led to a similar risk of all-cause mortality compared with control groups (1.3% with α-2 adrenergic agonists versus 1.7% with control; RR 0.80, 95% CI 0.61 to 1.04; participants = 14,081; studies = 16). Additionally, the risk of cardiac mortality was similar between treatment groups (0.8% with α-2 adrenergic agonists versus 1.0% with control; RR 0.86, 95% CI 0.60 to 1.23; participants = 12,525; studies = 5, high quality evidence). The risk of myocardial infarction was probably similar between treatment groups (RR 0.94, 95% CI 0.69 to 1.27; participants = 13,907; studies = 12, moderate quality evidence). There was no associated effect on the risk of stroke (RR 0.93, 95% CI 0.55 to 1.56; participants = 11,542; studies = 7; high quality evidence). Conversely, α-2 adrenergic agonists probably increase the risks of clinically significant bradycardia (RR 1.59, 95% CI 1.18 to 2.13; participants = 14,035; studies = 16) and hypotension (RR 1.24, 95% CI 1.03 to 1.48; participants = 13,738; studies = 15), based on moderate quality evidence.There was insufficient evidence to determine the effect of α-2 adrenergic agonists on all-cause mortality in cardiac surgery (RR 0.52, 95% CI 0.26 to 1.04; participants = 1947; studies = 16) and myocardial infarction (RR 1.01, 95% CI 0.43 to 2.40; participants = 782; studies = 8), based on moderate quality evidence. There was one cardiac death in the clonidine arm of a study of 22 participants. Based on very limited data, α-2 adrenergic agonists may have reduced the risk of stroke (RR 0.37, 95% CI 0.15 to 0.93; participants = 1175; studies = 7; outcome events = 18; low quality evidence). Conversely, α-2 adrenergic agonists increased the risk of bradycardia from 6.4% to 12.0% (RR 1.88, 95% CI 1.35 to 2.62; participants = 1477; studies = 10; moderate quality evidence), but their effect on hypotension was uncertain (RR 1.19, 95% CI 0.87 to 1.64; participants = 1413; studies = 9; low quality evidence).These results were qualitatively unchanged in subgroup analyses and sensitivity analyses. AUTHORS' CONCLUSIONS Our review concludes that prophylactic α-2 adrenergic agonists generally do not prevent perioperative death or major cardiac complications. For non-cardiac surgery, there is moderate-to-high quality evidence that these agents do not prevent death, myocardial infarction or stroke. Conversely, there is moderate quality evidence that these agents have important adverse effects, namely increased risks of hypotension and bradycardia. For cardiac surgery, there is moderate quality evidence that α-2 adrenergic agonists have no effect on the risk of mortality or myocardial infarction, and that they increase the risk of bradycardia. The quality of evidence was inadequate to draw conclusions regarding the effects of alpha-2 agonists on stroke or hypotension during cardiac surgery.

Comparison of the effects of patient-controlled epidural and intravenous analgesia on postoperative bowel function after laparoscopic gastrectomy: a prospective randomized study. Surg Endosc 2017; 31:4688-4696.

Abstract
BACKGROUND Although laparoscopic surgery significantly reduces surgical trauma compared to open surgery, postoperative ileus is a frequent and significant complication after abdominal surgery. Unlike laparoscopic colorectal surgery, the effects of epidural analgesia on postoperative recovery after laparoscopic gastrectomy are not well established. We compared the effects of epidural analgesia to those of conventional intravenous (IV) analgesia on the recovery of bowel function after laparoscopic gastrectomy. METHOD Eighty-six patients undergoing laparoscopic gastrectomy randomly received either patient-controlled epidural analgesia with ropivacaine and fentanyl (Epi PCA group) or patient-controlled IV analgesia with fentanyl (IV PCA group), beginning immediately before incision and continuing for 48 h thereafter. The primary endpoint was recovery of bowel function, evaluated by the time to first flatus. The balance of the autonomic nervous system, pain scores, duration of postoperative hospital stay, and complications were assessed. RESULTS The time to first flatus was shorter in the epidural PCA group compared with the IV PCA group (61.3 ± 11.1 vs. 70.0 ± 12.3 h, P = 0.001). Low-frequency/high-frequency power ratios during surgery were significantly higher in the IV PCA group, compared with baseline and those in the epidural PCA group. The epidural PCA group had lower pain scores during the first 1 h postoperatively and required less analgesics during the first 6 h postoperatively. CONCLUSIONS Compared with IV PCA, epidural PCA facilitated postoperative recovery of bowel function after laparoscopic gastrectomy without increasing the length of hospital stay or PCA-related complications. This beneficial effect of epidural analgesia might be attributed to attenuation of sympathetic hyperactivation, improved analgesia, and reduced opioid use.

Abstract
BACKGROUND Practitioners of traditional Chinese medicine know that auricular point acupressure (APP) using vaccaria seeds on the large intestine point (CO7) has a significant effect on postoperative gastrointestinal dysfunction. A standardized, clinical, research design will transform this clinical experience into scientific evidence, thus providing a basis to promote the wider use of this therapy. We aim to carry out a double-blind, randomized, controlled trial (RCT) to evaluate the efficacy and safety of APP treatment for gastrointestinal dysfunction after laparoscopic cholecystectomy. METHODS/DESIGN This study is a randomized, double-blind, controlled, single-center, clinical, pilot trial. It has been designed according to the Consolidated Standards of Reporting Trials (CONSORT 2010) guidelines as well as the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA). Study subjects are being selected from among hospitalized patients who have undergone laparoscopic cholecystectomy at the Department of Minimally Invasive Surgery of Tianjin Nankai Hospital. Qualified subjects will be assigned randomly either to the APP group or to the APP sham stimulation group on the basis of random numbers generated using SPSS 19.0. A specifically appointed investigator will be responsible for the randomization. The APP therapy (or sham stimulation) will be performed 6 h after surgery and every 12 h subsequently; six sessions will be conducted, each lasting 3 min. The first evaluation will be performed immediately before the first treatment (6 h after surgery) and, then, every 12 h for seven evaluations. The primary outcome is the time to first passage of flatus after surgery; the secondary outcome measures are abdominal distension, nausea, vomiting, time to first defecation, psychological status, and quality of life. DISCUSSION This pilot trial is a standardized, scientific, clinical trial designed to evaluate the efficacy and safety of APP treatment-using vaccaria seeds on CO7-for gastrointestinal dysfunction after laparoscopic cholecystectomy. We aim to provide objective evidence to promote this therapy in clinical practice. TRIAL REGISTRATION Chinese Clinical Trial Registry, ChiCTR-IPR-15007643 . Registered on 14 December 2015.

Abstract
BACKGROUND Lignocaine + adrenaline; a local anesthetic agent; frequently used for perilesional infiltration, maintains the stable hemodynamics and decreases the postoperative pain after maxillofacial surgery. α2 agonists have peripheral analgesic effects. This prospective study was to evaluate the effectiveness of perilesional dexmedetomidine administered preincisionally in addition to conventional lignocaine adrenaline combinations for reconstructive maxillofacial surgery in an ambulatory care setting. MATERIALS AND METHODS 76, American Society of Anesthesiologists I-II patients scheduled for unilateral traumatic maxillofacial surgeries were randomly allocated into group DL (n = 38) receiving 15 cc of 2% lignocaine + adrenaline (1:200,000) mixed with 1 μg/kg dexmedetomidine and group PL receiving 15 cc of 2% lignocaine + adrenaline with normal saline (placebo) via local wound infiltration 5 min prior to skin incision. Perioperative hemodynamics, time to first analgesic use, total analgesic need, bleeding, and side effects were recorded for each patient. RESULTS Dosage of supplemental propofol; total perioperative, postoperative, and postanesthesia care unit (PACU) fentanyl consumption was significantly lower (P = 0.0001, P= 0.0001, P= 0.0001, P= 0.004, respectively) in dexmedetomine treated group than placebo. Rescue analgesic requirement was significantly earlier in group PL than group DL. Group DL patients suffered from significantly less (P = 0.02) bleeding and surgeon's satisfaction score was also high in this group. Discharge from PACU was significantly earlier in group DL. Intraoperative hemodynamic parameters were significantly lower in group DL (P < 0.05) without any appreciable side effects. CONCLUSION Thus, prior dexmedetomidine local infiltration at the site of maxillofacial trauma has significantly reduced bleeding from wound site; perioperative fentanyl, propofol consumption, and subsequently ensured earlier discharge from PACU, better surgeon's satisfaction score with better hemodynamic control and lesser side effects.

Abstract
Intraperitoneal insufflation of carbon dioxide may affect the sympathetic activity that leads to changes in ventricular repolarization. This in turn can result in changes of heart rate-corrected QT (QTc) interval and Tpeak-Tend (Tp-e) interval. Dexmedetomidine is a highly selective α2-receptor agonist and has potential antiarrhythmic properties. This prospective, randomized, double-blinded, controlled study evaluated the effects of dexmedetomidine administration on QTc and Tp-e intervals during robot-assisted laparoscopic prostatectomy with steep Trendelenburg position.Fifty patients scheduled for robot-assisted laparoscopic prostatectomy randomly received either a continuous infusion of dexmedetomidine at a rate of 0.3 μg/kg/hour, from anesthetic induction until the end of the Trendelenburg position (dexmedetomidine group; n = 25), or the same volume of normal saline (control group; n = 25). Anesthesia was maintained with sevoflurane and remifentanil. The primary and secondary goals were to evaluate the effect of dexmedetomidine on the QTc and Tp-e interval changes. Mean arterial pressure, heart rate, end-tidal CO2, and end-tidal sevoflurane concentrations were assessed as well.Forty-seven patients (94%) completed the study. Dexmedetomidine significantly attenuated QTc interval prolongation and reduced the Tp-e interval, even though the baseline values of the QTc and Tp-e intervals were similar between the 2 groups (PGroup × Time = 0.001 and 0.014, respectively). Twenty-two patients (96%) in the control group and 13 (54%) in the dexmedetomidine group had QTc interval prolongation of >20 ms from the baseline value during surgery (P = 0.001). The maximum QTc interval prolongation from the baseline value during surgery was 46 ± 21 ms in the control group and 24 ± 21 ms in the dexmedetomidine group (mean ± SD, P = 0.001). Mean arterial pressure and heart rate were comparable between the groups.Continuous infusion of dexmedetomidine at a rate of 0.3 μg/kg/hour significantly attenuated the QTc interval prolongation induced by CO2 pneumoperitoneum with steep Trendelenburg position. Furthermore, dexmedetomidine reduced the Tp-e interval. Thus, dexmedetomidine administration may be effective for patients who are susceptible to the development of ventricular arrhythmia during robot-assisted laparoscopic prostatectomy.

Abstract
To investigate the effects of intraoperative dexmedetomidine on pain in highly nicotine-dependent patients after thoracic surgery.Highly nicotine-dependent men underwent thoracic surgery and received postoperative patient-controlled intravenous analgesia with sufentanil. In dexmedetomidine group (experimental group, n = 46), dexmedetomidine was given at a loading dose of 1 μg/kg for 10 minutes, followed by continuous infusion at 0.5 μg/kg/h until 30 minutes before the end of surgery. The saline group (control group, n = 48) received the same volume of saline. General anesthesia was administered via a combination of inhalation and intravenous anesthetics. If necessary, patients were administered a loading dose of sufentanil by an anesthesiologist immediately after surgery (0 hours). Patient-controlled analgesia was started when the patient's resting numerical rating scale (NRS) score was less than 4. Resting and coughing NRS scores and sufentanil dosage were recorded 0, 1, 4 hours, and every 4 hours until 48 hours after surgery. Dosages of other rescue analgesics were converted to the sufentanil dosage. Surgical data, adverse effects, and degree of satisfaction were obtained.Cumulative sufentanil dosage, resting NRS, and coughing NRS in the first 24 hours after surgery and heart rate were lower in the experimental compared with the control group (P <0.05). No patient experienced sedation or respiratory depression. Frequency of nausea and vomiting and degree of satisfaction were similar in both groups.Intraoperative dexmedetomidine was associated with reduced resting and coughing NRS scores and a sufentanil-sparing effect during the first 24 hours after thoracic surgery.
