Opioid-sparing effect of preemptive bolus low-dose ketamine for moderate sedation in opioid abusers undergoing extracorporeal shock wave lithotripsy: a randomized clinical trial Ketamine has been used as part of a multimodal analgesia regime in opioid abusers undergoing general anesthesia. We studied the opioid-sparing effect of a very low-dose bolus of ketamine as part of moderate sedation for opioid abuse patients undergoing extracorporeal shock wave lithotripsy.In this randomized, placebo (...) -controlled clinical trial, 190 opioid abusers were enrolled. They were stratified into 2 blocks based on their daily opioid consumption. Both blocks were then randomized to receive 0.1 mg/kg IV ketamine (group K) or placebo (group P). Lithotripsy was performed under moderate sedation with intermittent bolus doses of remifentanil (0.2 µg/kg) to alleviate pain. The total remifentanil dose (primary outcome) and respiratory adverse events (secondary outcome) were compared in the 2 groups.Remifentanil

Adjunctive Atropine Versus Metoclopramide: Can We Reduce Ketamine-associated Vomiting in Young Children? A Prospective, Randomized, Open, Controlled Study Pediatric procedural sedation and analgesia (PPSA) with ketamine administration occurs commonly in the emergency department (ED). Although ketamine-associated vomiting (KAV) is a less serious complication of ketamine administration, it seems to be cumbersome and not uncommon. The authors evaluated the incidence of KAV and the prophylactic (...) effect of adjunctive atropine and metoclopramide in children receiving ketamine sedation in the ED setting.This prospective, randomized, open, controlled study was conducted in children receiving ketamine sedation in the ED of a university-affiliated, tertiary hospital with 85,000 ED visits, including 32,000 pediatric patients from October 2010 to September 2011. The primary outcome was a measure of the incidence of KAV in the ED and after discharge according to the adjunctive drug administered
Ketamine for management of acute exacerbations of asthma in children. Asthma is the most common chronic disease in children, and children with asthma frequently visit the paediatric emergency departments with acute exacerbations. Some of these children fail to respond to standard therapy (aerosol beta(2)-agonist with or without aerosol anticholinergic and oral or parenteral corticosteroids) for acute asthma leading to prolonged emergency department stay, hospitalisation, morbidity (e.g (...) . barotrauma, intubation) and death, albeit rarely. Ketamine may relieve bronchospasm and is a potentially promising therapy for children with acute asthma who fail to respond to standard treatment.To evaluate the efficacy of ketamine compared to placebo, no intervention or standard care for management of severe acute asthma in children who had not responded to standard therapy.We identified trials from the Cochrane Airways Group Specialised Register of trials (CAGR) and ClinicalTrials.gov. We reviewed
Ketamine as an adjuvant to opioids for cancer pain. This is an update of the original review published in Issue 1, 2003. Ketamine is a commonly used anaesthetic agent, and in subanaesthetic doses is also given as an adjuvant to opioids for the treatment of cancer pain, particularly when opioids alone prove to be ineffective. Ketamine is known to have psychotomimetic (including hallucinogenic), urological and hepatic adverse effects.To determine the effectiveness and adverse effects of ketamine (...) as an adjuvant to opioids in the treatment of cancer pain.Studies were originally identified from MEDLINE (1966 to 2002), EMBASE (1980 to 2002), CancerLit (1966 to 2002), The Cochrane Library (Issue 1, 2001); by handsearching reference lists from review articles, trials, and chapters from standard textbooks on pain and palliative care. The manufacturer of ketamine (Pfizer Parke-Davis) provided search results from their in-house database, PARDLARS.An improved and updated search of the following was performed
The effect of perioperative intravenous lidocaine and ketamine on recovery after abdominal hysterectomy Perioperative ketamine infusion reduces postoperative pain; perioperative lidocaine infusion reduces postoperative narcotic consumption, speeds recovery of intestinal function, improves postoperative fatigue, and shortens hospital stay. However, it is unknown whether perioperative IV lidocaine and/or ketamine enhances acute functional recovery. We therefore tested the primary hypothesis (...) that perioperative IV lidocaine and/or ketamine in patients undergoing open abdominal hysterectomy improves rehabilitation as measured by a 6-minute walk distance (6-MWD) on the second postoperative morning.Women having open hysterectomy were anesthetized with sevoflurane, followed by patient-controlled morphine. Patients were factorially randomized to one of the following groups: (1) lidocaine and placebo, (2) placebo and ketamine, (3) placebo and placebo, or (4) lidocaine and ketamine. Lidocaine was given
Ketamine-propofol combination (ketofol) versus propofol alone for emergency department procedural sedation and analgesia: a randomized double-blind trial We determine whether a 1:1 mixture of ketamine and propofol (ketofol) for emergency department (ED) procedural sedation results in a 13% or more absolute reduction in adverse respiratory events compared with propofol alone.Participants were randomized to receive either ketofol or propofol in a double-blind fashion. Inclusion criteria were aged
Morphine and Ketamine Is Superior to Morphine Alone for Out-of-Hospital Trauma Analgesia: A Randomized Controlled Trial We assess the efficacy of intravenous ketamine compared with intravenous morphine in reducing pain in adults with significant out-of-hospital traumatic pain.This study was an out-of-hospital, prospective, randomized, controlled, open-label study. Patients with trauma and a verbal pain score of greater than 5 after 5 mg intravenous morphine were eligible for enrollment (...) . Patients allocated to the ketamine group received a bolus of 10 or 20 mg, followed by 10 mg every 3 minutes thereafter. Patients allocated to the morphine alone group received 5 mg intravenously every 5 minutes until pain free. Pain scores were measured at baseline and at hospital arrival.A total of 135 patients were enrolled between December 2007 and July 2010. There were no differences between the groups at baseline. After the initial 5-mg dose of intravenous morphine, patients allocated to ketamine

Procedural sedation with propofol for painful orthopaedic manipulation in the emergency department expedites patient management compared with a midazolam/ketamine regimen: a randomized prospective study The use of procedural sedation and analgesia to allow painful orthopaedic manipulations in the emergency department has become a standard practice over the last decade. Both propofol and midazolam/ketamine are attractive sedative regimens for routine use in the emergency department. We (...) hypothesized that sedation with propofol as compared with midazolam/ketamine will save time in the emergency department. The purpose of the present study was to compare the recovery time, the total sedation time, and the adverse events of procedural sedation and analgesia induced with propofol as compared with midazolam/ketamine.This prospective randomized study was conducted in the emergency department of a tertiary care, university-affiliated medical center. All sedations and orthopaedic manipulations

A randomized controlled trial of ketamine/propofol versus propofol alone for emergency department procedural sedation We compare the frequency of respiratory depression during emergency department procedural sedation with ketamine plus propofol versus propofol alone. Secondary outcomes are provider satisfaction, sedation quality, and total propofol dose.In this randomized, double-blind, placebo-controlled trial, healthy children and adults undergoing procedural sedation were pretreated (...) with intravenous fentanyl and then randomized to receive either intravenous ketamine 0.5 mg/kg or placebo. In both groups, this procedure was immediately followed by intravenous propofol 1 mg/kg, with repeated doses of 0.5 mg/kg as needed to achieve and maintain sedation. Respiratory depression was defined according to any of 5 predefined markers. Provider satisfaction was scored on a 5-point scale, sedation quality with the Colorado Behavioral Numerical Pain Scale, and propofol dose according to the total
Brief report: the effect of suggestion on unpleasant dreams induced by ketamine administration The use of ketamine may be associated with the recall of unpleasant dreams after sedation. We hypothesized that a positive suggestion before sedation could reduce the incidence of ketamine-induced unpleasant dreams. To test this hypothesis, we randomized 100 patients receiving sedation with ketamine for their procedure into 2 groups with 1 group having an anesthesiologist provide a mood-elevating (...) suggestion to the patient before ketamine administration (suggestion group), whereas in the control group no suggestion was provided. Patients were provided with a pleasantness/unpleasantness scale to rate "the overall mood of the dream" as very unpleasant (grade 1), quite unpleasant (grade 2), neither or mixed (grade 3), quite pleasant (grade 4), and very pleasant (grade 5). In those patients who lost consciousness, the frequencies of grades 1, 2, 3, 4, and 5 were 0%, 0%, 46%, 24%, and 30

Ketamine, but not priming, improves intubating conditions during a propofol-rocuronium induction Both ketamine and priming may shorten the onset time of rocuronium. This study investigates the effects of ketamine and priming as components of a propofol induction on intubating conditions and onset of neuromuscular block.This prospective randomized double-blind study was performed in 120 American Society of Anesthesiologists (ASA) I-II patients who were assigned to one of four groups of 30 (...) patients each: control, priming, ketamine, and ketamine-priming. Ketamine 0.5 mg x kg(-1) or saline was given before priming and induction. Rocuronium 0.06 mg x kg(-1) or saline was injected 2 min before propofol 2.5 mg x kg(-1). This was followed by rocuronium 0.6 mg x kg(-1) or by rocuronium 0.54 mg x kg(-1) if priming was given. Intubation was performed one minute later. Intubating conditions were graded as excellent, good, or poor. Heart rate, noninvasive blood pressure, and train-of-four (TOF
Preemptive analgesic effect of ketamine in patients undergoing elective cesarean section In this study, the preemptive effect of a small dose of ketamine on postoperative wound pain and morphine consumption in patients undergoing elective cesarean section was evaluated.In a randomized, double-blind clinical trial, 60 women with American Society of Anesthesiologists class I and II identification undergoing elective cesarean section were enrolled. In the case group, the patients received 0.5 mg (...) /kg ketamine, and in the control group, they received isotonic saline, 5 minutes before the induction of anesthesia. Anesthesia was induced with 4 mg/kg thiopental followed by 1.5 mg/kg succinylcholine. A further neuromuscular block was achieved by using 0.2 mg/kg of atracurium. Anesthesia was maintained with nitrous oxide 50% and halothane in oxygen. The lungs were mechanically ventilated. After fetus delivery, fentanyl (2 microg/kg) and morphine (0.15 mg/kg) were given intravenously
The early and delayed analgesic effects of ketamine after total hip arthroplasty: a prospective, randomized, controlled, double-blind study Ketamine has been shown to have a morphine-sparing effect soon after surgery. Nevertheless, whether this effect still exists after being combined with nonsteroidal antiinflammatory drugs and acetaminophen, and whether ketamine can decrease chronic pain after nononcologic surgery remain unclear. Thus, we designed a study to assess ketamine's effect on acute (...) and chronic postoperative pain when combined with multimodal analgesia after total hip arthroplasty (THA).Patients scheduled for primary nononcologic THA using standardized general anesthesia were randomized. They received IV ketamine before incision (0.5 mg/kg), and a 24-h infusion (2 microg x kg(-1) x min(-1)) or a similar blinded saline bolus and infusion. Postoperative analgesia included IV acetaminophen, ketoprofen, plus morphine/droperidol patient-controlled analgesia for 48 h. Data pertaining
