“…The unique sedative property of DEX may be the reason for the observed differences among the three groups in our study. Unlike in previously reported studies, the percentage of bradycardia, hypotension, nausea, and vomiting were comparable among the three groups during the surgery and in the PACU; this could be because of the shorter observation time, different types of surgery and patients, and mode of anesthesia administration (Muttu et al, 2005; Jessen Lundorf et al, 2016; Song et al, 2016). …”

Background: Chronic subdural hematoma (CSDH) is a very common clinical emergency encountered in neurosurgery. While both general anesthesia (GA) and monitored anesthesia care (MAC) can be used during CSDH surgery, MAC is the preferred choice among surgeons. Further, while dexmedetomidine (DEX) is reportedly a safe and effective agent for many diagnostic and therapeutic procedures, there have been no trials to evaluate the safety and efficacy of DEX vs. sufentanil in CSDH surgery.Objective: To evaluate the safety and efficacy of DEX vs. sufentanil in MAC during burr-hole surgery for CSDH.Methods: In all, 215 fifteen patients underwent burr-hole surgery for CSDH with MAC and were divided into three groups: Group D1 (n = 67, DEX infusion at 0.5 μg·kg−1 for 10 min), Group D2 (n = 75, DEX infusion at 1 μg·kg−1 for 10 min), and Group S (n = 73, sufentanil infusion 0.3 μg·kg−1 for 10 min). Ramsay sedation scale (RSS) of all three groups was maintained at 3. Anesthesia onset time, total number of intraoperative patient movements, hemodynamics, total cumulative dose of DEX, time to first dose and amount of rescue midazolam or fentanyl, percentage of patients converted to alternative sedative or anesthetic therapy, postoperative recovery time, adverse events, and patient and surgeon satisfaction scores were recorded.Results: The anesthesia onset time was significantly less in group D2 (17.36 ± 4.23 vs. 13.42 ± 2.12 vs. 15.98 ± 4.58 min, respectively, for D1, D2, S; P < 0.001). More patients in groups D1 and S required rescue midazolam to achieve RSS = 3 (74.63 vs. 42.67 vs. 71.23%, respectively, for D1, D2, S; P < 0.001). However, the total dose of rescue midazolam was significantly higher in group D1 (2.8 ± 0.3 vs. 1.9 ± 0.3 vs. 2.0 ± 0.4 mg, respectively, for D1, D2, S; P < 0.001). The time to first dose of rescue midazolam was significantly longer in group D2 (17.32 ± 4.47 vs. 23.56 ± 5.36 vs. 16.55 ± 4.91 min, respectively, for D1, D2, S; P < 0.001). Significantly fewer patients in groups S and D2 required rescue fentanyl to relieve pain (62.69 vs. 21.33 vs. 27.40%, respectively, for D1, D2, S; P < 0.001). Additionally, total dose of rescue fentanyl in group D1 group was significantly higher (212.5 ± 43.6 vs. 107.2 ± 35.9 vs. 98.6 ± 32.2 μg, respectively, for D1, D2, S; P < 0.001). Total number of patient movements during the burr-hole surgery was higher in groups D1 and S (47.76 vs. 20.00 vs. 47.95%, respectively, for D1, D2, S; P < 0.001). Four patients in D1 and five in S converted to propofol. The time to recovery for discharge from the PACU was significantly shorter in group D2 (16.24 ± 4.15 vs. 12.48 ± 3.29 vs. 15.91 ± 3.66 min, respectively, for D1, D2, S; P < 0.001). Results from the patient and surgeon satisfaction scores showed significant differences favoring group D2 (P < 0.05). More patients in groups D1 and S showed higher levels of the overall incidence of tachycardia and hypertension, and required higher doses of urapidil and esmolol (P < 0.05). Six patients experienced respiratory depression in group S...

“…[25] Of note, the hemodynamic stability, alleviated pain, and reduced stress responses offered by Dex might help patients quickly recover early postoperative walking which contributes to recovery of postoperative gastrointestinal motility. [26] Furthermore, as a α2 receptor adrenoreceptor agonist, Dex is able to accelerate intestinal wound healing by increasing intestinal epithelial cell proliferation. [27] …”

Dexmedetomidine improves gastrointestinal motility after laparoscopic resection of colorectal cancer

et al. 2016

Background:To investigate the effects of intraoperative application of dexmedetomidine (Dex) on early gastrointestinal motility after laparoscopic resection of colorectal cancer.Methods:In this prospective, randomized double-blind investigation, 60 patients who underwent laparoscopic resection of colorectal cancer were randomly allocated to receive Dex (DEX group, n = 30) or saline (CON group, n = 30). In the DEX group, Dex was loaded (1 μg/kg) before anesthesia induction and was infused (0.3 μg/kg/h) during surgery. Time to postoperative first flatus (FFL) and first feces (FFE), and time to regular diet were recorded. Serum diamine oxidase (DAO) activity and intestinal fatty acid-binding protein (I-FABP) were detected.Results:Both the time to the FFL (44.41 ± 4.51 hours vs 61.03 ± 5.16 hours, P = 0.02) and the time to the FFE (60.67 ± 4.94 hours vs 82.50 ± 6.88 hours, P = 0.014) were significantly shorter in the DEX group than the CON group. Furthermore, the time to regular diet of the DEX group was shorter than that of the CON group (76.15 ± 4.11 hours vs 91.50 ± 5.70 hours, P = 0.037). Both DAO and I-FABP increased significantly from beginning of surgery to postoperative day 1 in the CON group (2.49 ± 0.41 ng/mL vs 4.48 ± 0.94 ng/mL for DAO, P = 0.028, 1.32 ± 0.09 ng/mL vs 2.17 ± 0.12 ng/mL for I-FABP, P = 0.045, respectively), whereas no significant change was observed in the DEX group. Furthermore, patients in the DEX group had stable hemodynamics and shorter hospital stay than those in the CON group.Conclusion:Dex administration intraoperatively benefits recovery of gastrointestinal motility function after laparoscopic resection of colorectal cancer with stable hemodynamics during surgery though further studies are needed to explore the mechanisms of Dex on gastrointestinal motility.

“…A review and meta-analysis by Blaudszun et al [95] describes a reduced post-operative cumulative opioid consumption with clonidine (−4.1 mg morphine equivalents) and dexmedetomidine (−14.5 mg morphine equivalents), 24 h after surgery. A recent Cochrane review summarizes seven studies with a total of 492 participants and addresses the opioid-sparing effect of perioperative dexmedetomidine for acute pain after abdominal surgery in adults [96]. A modest reduction in opioid consumption in the first 24 h after surgery was found, although no clinically important differences in postoperative pain were noted.…”

Clinical Pharmacokinetics and Pharmacodynamics of Dexmedetomidine

et al. 2017

Dexmedetomidine is an α2-adrenoceptor agonist with sedative, anxiolytic, sympatholytic, and analgesic-sparing effects, and minimal depression of respiratory function. It is potent and highly selective for α2-receptors with an α2:α1 ratio of 1620:1. Hemodynamic effects, which include transient hypertension, bradycardia, and hypotension, result from the drug’s peripheral vasoconstrictive and sympatholytic properties. Dexmedetomidine exerts its hypnotic action through activation of central pre- and postsynaptic α2-receptors in the locus coeruleus, thereby inducting a state of unconsciousness similar to natural sleep, with the unique aspect that patients remain easily rousable and cooperative. Dexmedetomidine is rapidly distributed and is mainly hepatically metabolized into inactive metabolites by glucuronidation and hydroxylation. A high inter-individual variability in dexmedetomidine pharmacokinetics has been described, especially in the intensive care unit population. In recent years, multiple pharmacokinetic non-compartmental analyses as well as population pharmacokinetic studies have been performed. Body size, hepatic impairment, and presumably plasma albumin and cardiac output have a significant impact on dexmedetomidine pharmacokinetics. Results regarding other covariates remain inconclusive and warrant further research. Although initially approved for intravenous use for up to 24 h in the adult intensive care unit population only, applications of dexmedetomidine in clinical practice have been widened over the past few years. Procedural sedation with dexmedetomidine was additionally approved by the US Food and Drug Administration in 2003 and dexmedetomidine has appeared useful in multiple off-label applications such as pediatric sedation, intranasal or buccal administration, and use as an adjuvant to local analgesia techniques.
