RESUMEN

BACKGROUND: Thromboelastography (TEG) has recently become popular for assessment of whole blood coagulation in the operating room. Ketorolac, a potent injectable nonsteroidal anti-inflammatory drug (NSAID), is commonly used for postoperative analgesia. NSAID inhibit platelet aggregation in coagulation process. This study was designed to determine whether ketorolac used for postoperative analgesia can affect hemostatic function using a TEG. METHODS: Seventy-four female patients, ASA physical status 1 or 2, scheduled for an elective gynecologic surgery were randomly allocated into one of four groups (Group 1: n = 10, control without patient-controlled analgesia (PCA); Group 2: n = 21, PCA with morphine 60 mg; Group 3: n = 20, PCA with morphine 30 mg + ketorolac 90 mg; Group 4: n = 23, PCA with ketorolac 180 mg). Blood samples were obtained for TEG analysis preoperatively and 24, 48 and 72 h after surgery. Cumulative drug dosage, visual analog pain scale, satisfaction degree and side effects were measured at 24, 48 and 72 h after surgery. RESULTS: There were no significant differences in TEG parameters among the four groups at each time. There were no significant differences in visual analog pain scales and satisfaction degrees among the three groups using PCA for postoperative analgesia. Among the three groups using PCA for postoperative analgesia, Group 2 experienced more side effects. CONCLUSIONS: Ketorolac does not affect hemostatic function for 3 days after surgery when administrated as a PCA drug.

RESUMEN

BACKGROUND: Bacterial lipopolysaccharide (LPS), an endotoxin, can increase nitric oxide (NO) production by expression of an inducible isoforms of nitric oxide synthase (iNOS). Bacterial infections of the central nervous system dilate cerebral vessels and increase cerebral blood flow. We hypothesized that systemic and intraventricular application of bacterial lipopolysaccharide would increase cerebrospinal fluid (CSF) production due to increase in blood flow to choroid plexus caused by NO-induced vasodilation. METHODS: Ventriculocisternal perfusion was used to measure the production of CSF in pentobarbital-anesthetized rats. The lateral ventricle and cisterna magna were cannulated stereotactically and perfused continuously with artificial CSF with blue dextran 2000 as the indicator. Baseline collections of CSF began after steady state outflow was established; then, endotoxin was administered intravenously or intraventricularly. The baseline rate of CSF production was compared with that measured during 3 hours after endotoxin administration. RESULTS: The baseline rate of CSF production was 2.6 0.3 (2.2~3.5)microliter/minute in the rat. There were no significant changes in CSF production rate after intravenous or intraventriculr administration of endotoxin. CONCLUSIONS: We could not observe significant changes in CSF production rate with the ventriculocisternal perfusion method of measuring CSF production after intravenous or intraventriculr administration of endotoxin in the rats.
