BACKGROUND: The aim of the present study was to examine whether gabapentin, a new anti-epileptic agent with relatively low toxicities and side effects, could reduce postoperative pain. METHODS: Thirty-two patients scheduled for an elective total hysterectomy were investigated in this randomized, double blind, placebo-controlled study. The patients were randomized to receive either oral gabapentin 400 mg (gabapentin group, n = 16) or a matching placebo capsule (control group, n = 16) the night before and again 30 min before surgery as an adjunct to morphine patient-controlled analgesia (PCA). The visual analogue scale (VAS) for pain at rest and on movement, morphine consumption, overall satisfactions and postoperative side effects including sedation were recorded for 24 h after surgery. RESULTS: Total morphine consumption for 24 h after surgery was not significantly different between the two groups, but mean hourly morphine consumption during the period of 2 6 h after surgery was significantly greater in the control group. Movement VAS of gabapentin group measured at 6 h and 12 h after surgery was significantly lower than those of control group. There were no significant differences between the two groups with respect to the sedation score, patient's satisfaction and the frequencies of side effects. CONCLUSIONS: We observed that preoperatively administered oral gabapentin 800 mg reduced postoperative morphine consumption and incidental pain without increasing side effects. The addition of gabapentin to a morphine regimen may lower morphine consumption and provide better pain relief without increasing side effects.

PURPOSE: To evaluate the usefulness of the coaxial technique in US-guided breast core biopsy. Materials andMethods : Using the coaxial technique, US-guided breast core biopsy was performed in 49 breast lesions (40patients). Under US-guidance the 17-gauge, 13 cm long introducer needle was positioned proximal to the lesion.Once the needle was in place, the central trocar was removed and was replaced with the core biopsy needle. We usedan 18-gauge, 16-cm-long core biopsy needle with a 17 mm specimen notch. Four to eight tissue specimens wereobtained from each lesion, and the quality and quantity of specimens, procedure time, and complications and theirrate were evaluated. RESULTS: For 48 of 49 lesions, specimens were adequate for histopathologic diagnosis, andthe findings were as follows : six cases of invasive ductal carcinoma, one of ductal carcinoma in situ, 29 offibrocystic disease, eight of fibroadenoma, two of chronic inflammation, and two of sclerosing lesion. In 12lesions agreement between the pathologic results of needle core biopsy and surgical results was 100%. Theprocedure time was about 15 minutes and no significant complications were noted. CONCLUSION: In breast corebiopsy, the coaxial technique is simple and time-saving, and compared with stan-dard breast core biopsy, may alsobe less traumatic and decrease the potential risk of seeding the biopsy tract with malignant cells.

Purpose: Previous studies have suggested that serum phosphate concentration is a prognostic factor in critically ill patients. However, the association between changes in serum phosphate levels and prognosis of patients with trauma remains unclear. Materials and Methods: This study included patients with severe trauma who were treated at the emergency department. Delta phosphate (Δ phosphate) was defined as the difference between serum phosphate concentrations measured at baseline and after 24 hours from the initial measurement. Patients were divided into five groups according to their Δ phosphate levels: group I (Δ phosphate <-2 mg/dL), group II (Δ phosphate -2 to -0.5 mg/dL), group III (Δ phosphate -0.5 to 0.5 mg/dL), group IV (Δ phosphate 0.5 to 2 mg/dL), and group V (Δ phosphate ≥2 mg/dL). Results: Overall, 1905 patients with severe trauma were included in the analysis. The 30-day mortality was the lowest in group III and tended to increase in groups with a larger Δ phosphate in both the positive and negative directions (group I: 13.7%, group II:6.8%, group III: 4.6%, group IV: 6.6%, and group V: 26.8%). In multivariable analysis with group III as the reference group, the odds ratios (ORs) of mortality were statistically significant in group IV [OR, 1.92; 95% confidence interval (CI), 1.05–3.56] and group V (OR, 5.28; 95% CI, 2.47–11.24). Conclusion An increase in serum phosphate concentrations 24 hours after the initial measurement could be considered as an independent prognostic factor in patients with severe trauma.

Corpora amylacea (CA) are glycoproteinaceous inclusions that accumulate in the human brain during normal aging and neurodegenerative diseases. Although it has been suggested that the cellular sources of CA are neuronal or glial, the mechanisms underlying CA formation remain controversial. The aim of this study was to identify the source of CA in the human brain. Sample of the human brain tissues were obtained from the cadavers. H-E stain, periodic acid-Schiff (PAS) stain, and immunohistochemistry were performed in the brain tissues. Experimental induction of CA was also performed in rats. CA have been found in large numbers in the superficial, rather than in the deep, layer of the white matter in the lateral ventricle that is in contact with the cerebrospinal fluid (CSF) and sometimes near the blood vessels. Destroyed choroid plexi with psammoma bodies have been observed in the lateral ventricle of aged brains containing substantial numbers of CA. The cores of CA were mainly composed of amorphous PAS-positive materials, and glial fibrillary acidic protein-positive astrocytic processes were attached to the surface of the CA. Weak MAP2 was detected on a few CA in the gray matter such as dentate gyrus. PAS-positive CA were located on the border of the hippocampus contacting the CSF in the lateral ventricle in the cysteamine-induced CA animal model. Taken together, main cellular source of CA is astrocytes and CA core formation may be associated with CSF in the aged human brain.

Although perioperative pulmonary thromboembolisms (PTEs) are not rare, most anesthetists are unfamilar with the condition. We experience a case, which showed a sudden capnographic score drop, increased pumonary arterial pressure, and a D-shaped right ventricle by echocardiography in a femur surgery patient under general anesthesia. The case described provides an example of PTE and should remind anesthetists of the clinical course and treatment of this condition.

BACKGROUND: Haloperidol, a major tranquilizer similar to droperidol, has been found to have a potent antiemetic effect on postoperative nausea and vomiting (PONV), but the supporting evidence was incomplete, especially in Korea.Therefore we evaluated the prophylactic effect of haloperidol on opioid-based IV patient-controlled analgesia (PCA) related PONV in susceptible patients after gynecological laparoscopic surgery. METHODS: Ninety-six adult women scheduled gynecological laparoscopic surgery were enrolled in a randomized, double-blinded and placebo study.Patients received haloperidol 1 mg (Group H) or saline (Group C) 30 min before the end of surgery.Fentanyl-based IV PCA was administered after surgery.The incidences and severity of nausea, vomiting, rescue antiemetic administration, pain, and adverse effects (cardiac arrhythmias and extrapyramidal effects) were assessed for 24 h after surgery.The sedation score was recorded in the post-anesthesia care unit for 2 h. RESULTS: The incidences and severity of nausea and the number of antiemetic administration were significantly lower in Group H than Group C (P < 0.05). But the sedation and pain score were similar. There was no QTc prolongation or extrapyramidal symptom in both groups. CONCLUSIONS: Prophylactic haloperidol 1 mg is effective in preventing PONV related to fentanyl-based IV PCA, with less adverse effects, in patients undergoing gynecological laparoscopic surgery.

BACKGROUND: Most local anesthetics decrease neuromuscular transmission and potentiate the neuromuscular blocks of muscle relaxants. The purpose of this study was to examine the influence of lidocaine on it effects rocuronium onset and intubation conditions in rapid-sequence intubation and to compare with those of succinylcholine. METHODS: Seventy five ASA physical status 1 and 2 patients were randomly allocated to three groups. Group S received succinylcholine (1.0 mg/kg), Group R received rocuronium (0.6 mg/kg) and additional lidocaine (1.5 mg/kg) was given intravenously prior to the administration of rocuronium 0.6 mg/kg in Group RL. Anesthesia was induced with midazolam 0.03 mg/kg, fentanyl 2microgram/kg, and thiopental 5 mg/kg. Intubation was performed 60 seconds after the administration of muscle relaxants and intubation conditions were evaluated. Neuromuscular blockades were assessed by single twitch responses of the adductor pollicis after ulnar nerve stimulation by accelerography (0.1 Hz, 0.2 ms supramaximal stimuli). RESULTS: The onset time of Group S (47.8+/-11.3) was shorter than those of Group R (87.8+/-30.2) and Group RL (75.4+/-21.5), but no differences was observed between the onset times of Group R and Group RL. Intubation conditions were good or excellent in all groups. CONCLUSIONS: Additional lidocaine to rocuronium neither influences intubation condition nor accelerate the rocuronium onset, and it is cannot be viewed as an alternative for succinylcholine in rapid-sequence tracheal intubation.
