Preexisting Cognitive Impairment in Patients Scheduled for Elective Coronary Artery Bypass Graft Surgery
Anesth Analg 2007 104: 1023-1028. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We found that 35% of 349 patients had cognitive impairment before coronary artery bypass graft (CABG) surgery, based on a comparison of psychometric testing results with that obtained from 170 healthy control individuals free of cardiovascular disease. These results suggest that impaired cognition before surgery must be considered when assessing the effects of CABG surgery on cognitive performance.

Pressure-Controlled Versus Volume-Controlled Ventilation During One-Lung Ventilation for Thoracic Surgery
Anesth Analg 2007 104: 1029-1033. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We compared pressure-controlled ventilation with volume-controlled ventilation during one-lung ventilation in patients with good preoperative pulmonary function undergoing thoracic surgery. We found no difference in arterial oxygenation between ventilatory management strategies, but pressure-controlled ventilation did lead to lower peak airway pressures.

There Is No Dose-Escalation Response to Dexamethasone (0.0625–1.0 mg/kg) in Pediatric Tonsillectomy or Adenotonsillectomy Patients for Preventing Vomiting, Reducing Pain, Shortening Time to First Liquid Intake, or the Incidence of Voice Change
Anesth Analg 2007 104: 1052-1058. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: There is no significant difference in five escalating doses of dexamethasone (0.0625-1.0 mg/kg) in children after adenotonsillectomy for preventing vomiting, reducing pain, or shortening time to first oral intake. The lowest dose of dexamethasone (0.0625 mg/kg) is as effective as the highest dose (1 mg/kg).

Lidocaine, MK-801, and MAC
Anesth Analg 2007 104: 1098-1102. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Although lidocaine is a sodium channel blocker, and, thereby, might be predicted to decrease MAC by decreasing the release of N-methyl-d-aspartate from nerve terminals, this does not appear to be the primary means by which lidocaine decreases MAC.

The Effects of Fentanyl on the Contractile Response of Ovalbumin-Sensitized Rat Trachea
Anesth Analg 2007 104: 1103-1108. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Although fentanyl affects airway responsiveness, the mechanisms involved are not fully understood. Using sensitized rat trachea we found that fentanyl attenuates airway hyperresponsiveness by inhibition of cholinergic nerves on the smooth muscle. Fentanyl would be a relatively useful analgesic for patients with antigen-induced asthma.

The Effects of Systemic Lidocaine on Airway Tone and Pulmonary Function in Asthmatic Subjects
Anesth Analg 2007 104: 1109-1115. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Lidocaine can reduce airway responsiveness to drugs that cause bronchospasm but does not reduce baseline airway tone. Instead, it caused a significant amount of increased tone and airway narrowing. Therefore, although lidocaine can prevent intubation-induced bronchospasm, the airways should be constantly monitored by auscultation, even during IV lidocaine administration.

Lack in Effects of Therapeutic Concentrations of Dexmedetomidine and Clonidine on the Neuromuscular Blocking Action of Rocuronium in Isolated Rat Diaphragms
Anesth Analg 2007 104: 1116-1120. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: We demonstrated by in vitro experiments using rat diaphragms that very high, but not therapeutic, concentrations of clonidine and dexmedetomidine enhance the rocuronium-induced neuromuscular block mediating non-{alpha}-2 adrenergic mechanisms. The results imply that these {alpha}-2 adrenoceptor agonists do not influence nondepolarizing neuromuscular block at clinically relevant concentrations.

Prolongation of Intrathecal and Sciatic Nerve Blocks Using a Complex of Levobupivacaine with Maltosyl-ß-Cyclodextrin in Rats
Anesth Analg 2007 104: 1121-1128. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The complex of levobupivacaine with maltosyl-{beta}-cyclodextrin prolonged the anesthetic effect of levobupivacaine in both intrathecal and sciatic nerve blocks in rats. This complex may be used to prolong the effect of a long-acting local anesthetic such as levobupivacaine 1.4-2.0 times through a conduction block and to supply adequate postoperative analgesia.

The Effects of Sevoflurane Anesthesia on Rat Brain Proteins: A Proteomic Time-Course Analysis
Anesth Analg 2007 104: 1129-1135. [Abstract] [Full Text] [PDF] [Data Supplement]   

IMPLICATIONS: Changes in cerebral protein expression may persist for several days after anesthesia. In the present study, we showed that sevoflurane anesthesia induced direct changes in protein expression which persisted for 72 h after anesthesia. These changes may contribute to long-term effects such as neurocognitive dysfunction after anesthesia.

The Effects of General Anesthetics on P2X₇ and P2Y Receptors in a Rat Microglial Cell Line
Anesth Analg 2007 104: 1136-1144. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Microglial cells coordinate inflammatory brain responses to hypoxia and trauma. Although anesthetics produce neuroprotective effects through neuronal mechanisms, little is known about how they modulate microglial responses in the pathological state. Our results suggest that IV anesthetics, particularly thiopental and propofol, may modulate microglial functions through P2X7 receptors in pathological conditions.

Cricoid Pressure Impedes Insertion of, and Ventilation Through, the ProSeal Laryngeal Mask Airway in Anesthetized, Paralyzed Patients
Anesth Analg 2007 104: 1195-1198. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This prospective cross-over study demonstrated that cricoid pressure applied before insertion of the ProSeal laryngeal mask airway (ProSeal LMA) might prevent correct placement. Temporarily releasing cricoid pressure during insertion will facilitate advancing the ProSeal LMA to the proper position.

Perineural Resiniferatoxin Prevents the Development of Hyperalgesia Produced by Loose Ligation of the Sciatic Nerve in Rats
Anesth Analg 2007 104: 1210-1216. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: This study evaluated the potential of perineural resiniferatoxin (RTX) for prevention of neuropathy induced by peripheral nerve injury. Perineural RTX administered before surgery completely prevented ligation-induced reduction in withdrawal latency, increase in paw lift duration, and increase in withdrawal frequency to von Frey filaments. The preventive effect of RTX on the development of deficits in hindpaw posture was pronounced, but not complete.

Refinement of Symptoms of Neuropathic Pain Measurements After Various Transections of the Nerve Endings of the Sciatic and Femoral Nerve in Rats: An Exploratory Behavioral Analysis
Anesth Analg 2007 104: 1236-1245. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: The neuropathic pain behavior after transection of the three peripheral nerves of the rat hindlimb resulted in different degrees and severity of neuropathic pain behaviors. Transection of the tibial nerve alone, or in combination with the sural or the saphenous nerve, induces the development of neuropathic pain behavior characterized by the presence of mechanical hyperalgesia and cold allodynia.

Amitriptyline Is a Potent Blocker of Human Kv1.1 and Kv7.2/7.3 Channels
Anesth Analg 2007 104: 1256-1264. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Amitriptyline potently blocks human Kv1.1 and Kv7.2/7.3 channels. Since amitriptyline inhibited these channels at toxicologically relevant plasma concentrations, our results suggest a role for these channels in the neuroexcitatory side effects of amitriptyline. The Kv7.2/7.3 opener retigabine reverses the effects of amitriptyline, indicating that a combination of both drugs could be of additional benefit in the therapy of neuropathic pain.

Neurostimulation in Ultrasound-Guided Infraclavicular Block: A Prospective Randomized Trial (Medical Intelligence)
Anesth Analg 2007 104: 1275-1280. [Abstract] [Full Text] [PDF]  

IMPLICATIONS: Ultrasound-guided infraclavicular block is more rapidly performed and yields a higher success rate when visualization of local anesthetic spread is used as the end point for injection rather than neurostimulation. Posterolateral spread of local anesthetic around the axillary artery predicts successful block and circumvents the need for direct nerve visualization.
