Pediatric anesthetic guidelines for the management of preoperative fasting of clear fluids are currently 2 hours. The traditional 2 hours clear fluid fasting time was recommended to decrease the risk of pulmonary aspiration and is not in keeping with current literature. It appears that a liberalized clear fluid fasting regime does not affect the incidence of pulmonary aspiration and in those who do aspirate, the sequelae are not usually severe or long-lasting. With a 2-hour clear fasting policy, the literature suggests that this translates into 6-7 hours actual duration of fasting with several studies up to 15 hours...

INTRODUCTION: The optimal intravenous fluid regimen for patients undergoing major abdominal surgery is unclear. However, results from many small studies suggest a restrictive regimen may lead to better outcomes. A large, definitive clinical trial evaluating perioperative fluid replacement in major abdominal surgery, therefore, is required. METHODS/ANALYSIS: We designed a pragmatic, multicentre, randomised, controlled trial (the RELIEF trial). A total of 3000 patients were enrolled in this study and randomly allocated to a restrictive or liberal fluid regimen in a 1:1 ratio, stratified by centre and planned critical care admission...

BACKGROUND: This study compares the accuracy of cerebral monitoring systems in detecting cerebral ischemia during carotid endarterectomy. METHODS: The authors compared transcranial Doppler sonography (TCD), near-infrared spectroscopy (NIRS), stump pressure (SP) measurement, and somatosensory evoked potentials (SEP) in 48 patients undergoing carotid surgery during regional anesthesia. Cerebral ischemia was assumed when neurologic deterioration occurred. During clamping, the minimum mean middle cerebral artery velocity (TCD(min)), its percentage change (TCD%), the minimum regional saturation of oxygen (NIRS(min)), its percentage change (NIRS%), the mean SP, and the changes of SEP amplitude were recorded...

PURPOSE: Intranasal dexmedetomidine premedication is a newly introduced method for reducing stress and anxiety before general anesthesia in children. We performed a meta-analysis to identify the effects of intranasal dexmedetomidine premedication in children. SOURCE: We conducted a systematic review to find published randomized-controlled trials using intranasal dexmedetomidine as premedication. We searched databases in EMBASE™, MEDLINE®, and the Cochrane Controlled Trials Register using the Ovid platform...

Perineural dexamethasone has gained popularity in regional anaesthesia to prolong the duration of analgesia, but its advantage over systemic administration is disputed. The objective of this meta-analysis was to compare the analgesic efficacy of both routes of administration during peripheral nerve block. The methodology followed the PRISMA statement guidelines. The primary outcome was the duration of analgesia analysed according to the type of local anaesthetic administered (bupivacaine or ropivacaine). Secondary outcomes included cumulative opioid consumption in morphine i...

BACKGROUND: Lidocaine administration produces pain due to its acidic pH. OBJECTIVES: The objective of this review was to determine if adjusting the pH of lidocaine had any effect on pain resulting from non-intravascular injections in adults and children. We tested the hypothesis that adjusting the pH of lidocaine solution to a level closer to the physiologic pH reduces this pain. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, to June 2010); Ovid MEDLINE (1966 to June 2010); EMBASE (1988 to June 2010); LILACS (1982 to June 2010); CINAHL (1982 to June 2010); ISI Web of Science (1999 to June 2010); and abstracts of the meetings of the American Society of Anesthesiologists (ASA)...

BACKGROUND: The risk of severe neurologic injury after neuraxial blockade is extremely rare among the general population. However, patients with preexisting neural compromise may be at increased risk of further neurologic sequelae after neuraxial anesthesia or analgesia. METHODS: We retrospectively investigated 567 patients with a preexisting peripheral sensorimotor neuropathy or diabetic polyneuropathy who subsequently underwent neuraxial anesthesia or analgesia...

In ultrasound-guided central venous catheterization, there is no standard technique either for the needle tip visualization or for the adequate needle angle and entry to the skin with short-axis view under out-of-plane technique. In the present study, we propose a novel technique named "stepwise flashing with triangulation", and the efficacy of this technique is assessed. Before and after a didactic session in which the technique was explained, 12 novice residents were asked to position the needle tip on or into the imitation vessels and to avoid deeper penetration by using an agar tissue phantom with ultrasound guidance...

BACKGROUND: Regional anesthesia (RA) provides excellent anesthesia and analgesia for many surgical procedures. Anesthesiologists and patients must understand the risks in addition to the benefits of RA to make an informed choice of anesthetic technique. Many studies that have investigated neurological complications after RA are dated, and do not reflect the increasing indications and applications of RA nor the advances in training and techniques. In this brief narrative review we collate the contemporary investigations of neurological complications after the most common RA techniques...

BACKGROUND: The transversus abdominis plane (TAP) block has been shown to provide effective postoperative analgesia in lower abdominal surgery. Subcostal TAP block has also been proposed as a new technique to provide analgesia for the supraumbilical abdomen. We compared the analgesic and opioid-sparing effects of a single-injection subcostal TAP block with continuous thoracic epidural analgesia and IV opioid analgesia. METHODS: Ninety patients undergoing elective radical gastrectomy were randomized to receive either combined general-subcostal TAP anesthesia (group TAP), combined general-epidural anesthesia (group EA), or general anesthesia (group GA), and were analyzed on an intention-to-treat basis...

BACKGROUND: Optimal analgesia for total knee arthroplasty remains challenging. Many modalities have been used, including peripheral nerve block, periarticular infiltration, and epidural analgesia. However, the relative efficacy of various modalities remains unknown. The authors aimed to quantify and rank order the efficacy of available analgesic modalities for various clinically important outcomes. METHODS: The authors searched multiple databases, each from inception until July 15, 2016...

BACKGROUND: Dexmedetomidine, a specific α(2) agonist, has an analgesic-sparing effect and reduces emergence agitation. We compared an intraoperative dexmedetomidine infusion with bolus fentanyl to reduce perioperative opioid use and decrease emergence agitation in children with obstructive sleep apnea syndrome undergoing adenotonsillectomy (T&A). METHODS: One hundred twenty-two patients with obstructive sleep apnea syndrome undergoing T&A, ages 2 to 10 years, completed this prospective, randomized, U...

BACKGROUND: Administration of dexmedetomidine (DEX) in the pediatric population for its sedative, analgesic, and anxiolytic properties has been widely reported, despite there being no label indication approved by the U.S. Food and Drug Administration for pediatric patients. Infusions of DEX, rather than bolus administration, are recommended to attenuate the hemodynamic response caused by the α2-adrenoreceptor agonist. In this prospective, double-blind, randomized study, we examined the effect of rapid IV bolus injection of DEX on emergence agitation and the hemodynamic response in a large sample of children undergoing tonsillectomy with or without adenoidectomy, with or without myringotomy, and/or tympanostomy tube insertion...

Importance: Despite increased focus on reducing opioid prescribing for long-term pain, little is known regarding the incidence and risk factors for persistent opioid use after surgery. Objective: To determine the incidence of new persistent opioid use after minor and major surgical procedures. Design, Setting, and Participants: Using a nationwide insurance claims data set from 2013 to 2014, we identified US adults aged 18 to 64 years without opioid use in the year prior to surgery (ie, no opioid prescription fulfillments from 12 months to 1 month prior to the procedure)...

Although needleless connectors (NC) are frequently used in the perioperative setting, the potential of modern NCs to slow delivery of IV fluids has not been thoroughly studied. We examined flow characteristics of 5 NC models during pressurized delivery of crystalloid and banked red blood cells from a Level 1 warmer through various IV catheters. Crystalloid flow rates were reduced by 29% to 85% from control in catheters >18 gauge, while red blood cell flow reductions ranged from 22% to 76% in these catheters (all P < 0...

REVIEW
Harriet Daykin
Opioids remain the mainstay of analgesia for the treatment of moderate to severe acute pain. Even in the young, the use of opioids can be associated with an increased incidence of post-operative complications such as respiratory depression, vomiting, pruritus, excessive sedation, slowing of gastrointestinal function, and urinary retention. The need to manage acute pain in the older patient is becoming more common as the population ages, and increasingly older patients are undergoing more major surgery. Medical conditions are more common in older people and can result in the requirement of systemic analgesia for fractures, malignancy, nociceptive or neuropathic pain and peripheral vascular disease...

Background: During fluid challenge, volume expansion (VE)-induced increase in cardiac output (Δ VE CO) is seldom measured. Methods: In patients with shock undergoing strictly controlled mechanical ventilation and receiving VE, we assessed minimally invasive surrogates for Δ VE CO (by transthoracic echocardiography): fluid-induced increases in end-tidal carbon dioxide (Δ VE E'CO2 ); pulse (Δ VE PP), systolic (Δ VE SBP), and mean systemic blood pressure (Δ VE MBP); and femoral artery Doppler flow (Δ VE FemFlow)...
