IMPLICATIONS: Sevoflurane enhances cardiac preconditioning induced by regular ethanol consumption, an effect, mediated in part by protein kinase and mitochondrial KATP channels. Modulation of nitric oxide synthase expression by regular ethanol consumption may also play a role in this enhanced cardioprotection.
IMPLICATIONS: Protection by isoflurane preconditioning is highly effective in diseased postinfarct remodeled rat hearts and depends on activation of the two well-established key signaling elements, protein kinase B and mitochondrial ATP-dependent potassium channel.
IMPLICATIONS: Administration of the perfluorocarbon perfluoro-tert-butylcyclohexane during cardiopulmonary bypass resulted in an excessive inflammatory response, hypotension, myocardial contraction band necrosis, and a high mortality rate in rats. This study suggests that further investigations are warranted before clinical administration of this compound is pursued.
IMPLICATIONS: Platelet transfusions are risk factors for patient survival after liver transplantation, which appears to be independent from other well-known risk factors. These findings call for a cautious use of platelet transfusions in patients undergoing liver transplantation.
IMPLICATIONS: The optimal method for detecting venous air embolism has not been well defined. We compared a new technology, transvenous intracardiac echocardiography with transesophageal echocardiography and precordial Doppler in a swine model, evaluating detection and image-guided catheter aspiration of venous air embolism. The greater sensitivity of intracardiac echocardiography in this model suggests that clinical studies may be warranted.
IMPLICATIONS: We present a case in which pulmonary artery catheterization via the left internal jugular approach resulted in positioning of the catheter in the ascending aorta. Subsequent postmortem examination revealed the presence of a partial anomalous pulmonary venous connection between the left brachocephalic vein and an otherwise normally developed left upper pulmonary vein. Anatomic considerations suggest that such placement may be more likely with left-sided cannulation approaches.
IMPLICATIONS: During thoracotomy, a tension pneumothorax should be considered in the presence of increasing airway pressures, even in the absence of marked hypoxemia and hypotension.
IMPLICATIONS: This study found that clinicians rated the complexity, compatibility, relative advantage, and overall clinical utility higher for the r-FLACC and NAPI compared with the NCCPC-PV, suggesting that these tools may be more readily adopted into clinical practice.
IMPLICATIONS: In this prospective study of the effects of dexmedetomidine (DEX) on cardiac electrophysiology in 12 children, we found that DEX significantly depressed sinus and atrioventricular nodal function. Heart rate decreased and arterial blood pressure increased during administration of DEX. The use of DEX may not be desirable during electrophysiology study and may be associated with adverse effects in patients at risk for bradycardia or atrioventricular nodal block.
IMPLICATIONS: Therapeutic hypercapnia, which is used to deliberately increase CO2, may also be used for minimizing the deleterious effect of CO2 insufflation during pediatric video-assisted thoracoscopic surgery.
IMPLICATIONS: Accurate placement of local anesthetic around the ilioinguinal/iliohypogastric nerves in children is seldom possible when landmark-based techniques are used. In the majority of patients, the local anesthetic was inaccurately placed in adjacent anatomical structures with unpredictable block results.
IMPLICATIONS: Continuous infraclavicular block offers good intraoperative and postoperative pain relief for an extended period. There is always an issue of catheter dislodgement. Slight modifications in the technique can help to secure the catheter.
IMPLICATIONS: The authors describe the use of ultrasound to guide placement of a caudal block in an infant with difficult anatomy.
IMPLICATIONS: The study demonstrates that the clinical outcome after an infusion of remifentanil 0.085 {micro}g {middle dot} kg 1 {middle dot} min 1 compares favorably with 66% N2O in a desflurane/fentanyl anesthetic during ambulatory orthopedic surgery. Therefore, using an infusion of remifentanil may be an effective strategy for those who wish to avoid N2O yet want to achieve similarly rapid recovery profiles.
IMPLICATIONS: Mirtazapine is a new antidepressant whose mechanism of action includes blockade of the 5-HT2 and 5-HT3 receptors. Premedication with mirtazapine reduced preoperative anxiety and postoperative nausea and vomiting.
IMPLICATIONS: We compared the hemodynamic, analgesic, sedative, and respiratory effects of dexmedetomidine and propofol in combination with small-dose fentanyl during extracorporeal shockwave lithotripsy (ESWL). Dexmedetomidine in combination with small-dose fentanyl can be useful during ESWL and it may be a valuable alternative to propofol.
IMPLICATIONS: IV ketamine 0.5 and 0.75 mg/kg provides a more rapid onset of effect than meperidine 25 mg for the treatment of postoperative shivering, but these doses of ketamine had a greater incidence of side effects.
IMPLICATIONS: Laryngeal mask airway anesthesia induced with propofol reduced acute postoperative pharyngeal morbidity in terms of sore throat, dysphonia, dysphagia, nausea, and vomiting, compared with thiopental. The benefits should encourage the use of propofol for induction of laryngeal mask airway anesthesia.
IMPLICATIONS: Xenon does not affect 11C-flumazenil binding in the living human brain, indicating that the anesthetic effect of xenon is not mediated via the {gamma}-aminobutyric acid type A receptor system.
IMPLICATIONS: We examined how different anesthetics per se affect variables of glucose metabolism in nonfasted rats, i.e., under similar hemodynamic conditions and in the absence of major surgical stress. Our results indicate that choice of anesthetic strategies may be an important determinant whether, and to what degree, hyperglycemia develops.
IMPLICATIONS: A continuous epidural infusion of ropivacaine inhibits CYP2D6 activity, but not enough to affect the metabolism of other drugs in patients with normal CYP2D6 activity.
IMPLICATIONS: We present a protocol for the rapid detection of the atypical- and Kalow-variant in the butyrylcholinesterase gene. Detection of these frequent variants is useful in pharmacokinetic studies investigating drugs metabolized by this enzyme.
IMPLICATIONS: Spectral entropy predicts motor but not hemodynamic response to intubation and skin incision.
IMPLICATIONS: This study shows that the STG-22TM provides continuous glucose measurement; however, the need to confirm measurements with another reliable device is not eliminated.
IMPLICATIONS: Low frequency heart rate variability correlates with plasma norepinephrine, arterial blood pressure, and heart rate during pheochromocytoma surgery.
IMPLICATIONS: Noninvasive radial artery tonometry is not suitable to determine cardiac output in critically ill hemodynamically unstable patients.
IMPLICATIONS: Changes in dead space fraction can be used to evaluate the response to recruitment maneuvers in perioperative patients.
IMPLICATIONS: A new modified technique for emergency cricothyroidotomy offers no relevant advantages over the standard technique.
IMPLICATIONS: The transversus abdominis plane block, when used as part of a multimodal analgesic regimen, resulted in better analgesia and decreased supplemental opioid consumption after cesarean delivery.
IMPLICATIONS: Software continuously scanned anesthesia information system data for missing clinical documentation. A one-time prompt was sent via pager to the anesthesiologist. Within 5 days, missing documentation decreased by more than 70%, and the improvement was sustained even on days when no prompts were sent.
IMPLICATIONS: Video-assisted preanesthesia patient education increased patients' knowledge, but did not reduce their anxiety nor increase their satisfaction. The duration of the preanesthetic interview was markedly extended (e.g., from patients' questions) among patients both viewing the video and scheduled for anesthesia with invasive monitoring.
IMPLICATIONS: Significant electroencephalogram (EEG) experience is an Accreditation Council for Graduate Medical Education requirement for anesthesiology training. This article provides a new educational EEG teaching methodology combining the expertise of a fellowship-trained neurophysiologist and neurology attending during the neurosurgical intensive care unit rotation to provide additional educational opportunities.
IMPLICATIONS: Tactical planning of additional operating room block time for capacity expansion must be differentiated from a second, operational stage of matching staffing to expected workload. Ten reasons are presented to explain why tactical planning of block time should not be based on utilization.
IMPLICATIONS: Dantrolene, given into the cerebral ventricles reduced necrotic, but not apoptotic, injury in this neonatal rodent model of cerebral ischemia with hypoxia.
IMPLICATIONS: We compared two different models of assessment of dynamic cerebral autoregulation. They agreed relatively well in a cohort of 50 severely head-injured patients. The outcome after head injury was better in patients with preserved cerebral autoregulation.
IMPLICATIONS: Third molar extraction was followed by coma due to nonfatal cerebral air embolism from the use of a high speed dental drill.
IMPLICATIONS: Shivering threshold reduction during neuraxial anesthesia may result from an apparent increase in the lower body skin temperature.
IMPLICATIONS: We studied the efficacy of the Pentax-AWS (Tokyo, Japan), a new portable, battery-operated video-laryngoscope, in 100 patients. A full view of the glottis was obtained in 99 patients, and tracheal intubation was successful in 98 patients.
IMPLICATIONS: A facial emphysema occurred while using the Bonfils fiberscope and high-flow oxygen insufflation.
IMPLICATIONS: There is less postoperative pain and morphine use after general anesthesia with propofol than with isoflurane, a finding unaffected by the use of nicotine.
IMPLICATIONS: To distinguish acute complex regional pain syndrome type I fracture patients from control fracture patients with and without complaints, thermographic recordings of extremities under resting conditions can be used only as a supplementary diagnostic tool.
IMPLICATIONS: After laparoscopic surgery, intraperitoneal meperidine and ropivacaine, alone or in combination, did not produce better pain relief or opioid dose-sparing compared with systemic opioid.
IMPLICATIONS: The addition of ketamine in a 1:1 ratio to morphine IV patient-controlled analgesia did not benefit postoperative analgesia
IMPLICATIONS: We postulated that perioperative cyclooxygenase 2 inhibition would significantly reduce postoperative morphine requirements after major thoracic surgery and investigated the site of this potential analgesic effect. Nimesulide, at a dose of 90 mg twice daily, does not influence pain scores and morphine requirements after major thoracic surgery and does not appear to influence cerebrospinal fluid prostaglandin levels perioperatively.
IMPLICATIONS: In this study, the addition of epinephrine 4 {micro}g/mL (12 32 {micro}g/h) to a low-dose mixture of ropivacaine and fentanyl did not improve lumbar continuous epidural analgesia after total knee arthroplasty. This confirms earlier findings that lower dose epinephrine as an adjuvant to continuous epidural analgesia given at a lumbar level has no, or only limited, beneficial effects on postoperative pain relief.
IMPLICATIONS: The median effective analgesic dose (median value and 95% confidence interval) of preemptive gabapentin in patients undergoing elective posterior lumbar spinal fusion was 21.7 mg/kg (19.9 23.5 mg/kg).
IMPLICATIONS: We evaluated the analgesic effectiveness and side effects of IV patient-controlled morphine, pethidine and tramadol for postoperative pain management. The use of these drugs resulted in equivalent pain scores and side effects, but our tramadol group required more rescue analgesic doses of fentanyl.
IMPLICATIONS: Repetitive administration of epidural ropivacaine starting 7 days after injury partly reverses the thermal hyperalgesia and mechanical allodynia that develops after chronic constrictive injury in rats.
IMPLICATIONS: Bupivacaine stimulates cyclooxygenase-2 gene expression after tissue injury. This may increase overall prostaglandin E2 production, resulting in an enhanced inflammatory response and postoperative pain.
IMPLICATIONS: The combination of intraarticular morphine, ketorolac, and ropivacaine combined with intraarticular patient-controlled regional analgesia using an elastomeric pump for delivery of local anesthetics is more effective than IV ketorolac, but only during the initial postoperative period.
IMPLICATIONS: Pretreatment with oral gabapentin had no effect on the spread of sensory block or the regression of motor block but was associated with lower systolic arterial blood pressure values in patients undergoing spinal anesthesia with ropivacaine.
IMPLICATIONS: We examined ultrastructural aspects of spinal nerve root cuffs such as their cellular and fibrillar components using special histological staining methods, transmission and scanning electron microscopy from six human cadavers. The presence of few capillaries and short distance between fat and axons may affect the passage of epidurally injected substances towards nerve root axons.
