Randomized Controlled TrialIntravenous paracetamol improves the quality of postoperative analgesia but does not decrease narcotic requirements.
Paracetamol, a centrally acting inhibitor of cyclooxygenase, has less gastrointestinal and platelet-inhibiting side effects and is clinically better tolerated than nonsteroidal anti-inflammatory drugs. Therefore, it will be ideally suited for postoperative pain relief. In this prospective, double-blind, randomized, placebo-controlled study, we evaluated the analgesic efficacy, opioid-sparing effect and effects on opioid-related adverse effects of intravenous (IV) paracetamol in combination with IV morphine after lumbar laminectomy and discectomy. ⋯ Vomiting in group 2 was significantly higher (P=0.027). Significantly more patients in the paracetamol group rated their pain management as excellent (45% vs. 5%). Although repeated IV paracetamol usage after lumbar laminectomy and discectomy did not demonstrate a significant opioid-sparing effect, it did decrease visual analog scale scores at certain evaluation times and incidence of vomiting and increase patient satisfaction.

Admission microalbuminuria and neurologic outcomes in intensive care unit patients with spontaneous intracerebral hemorrhage.
This study was performed to determine the prevalence and the prognostic significance of microalbuminuria in patients admitted to intensive care unit (ICU) after spontaneous intracerebral hemorrhage (ICH). From May 2004 to April 2006, we studied 59 consecutive ICH patients verified using computed tomography and admitted to our ICU within a day after stroke. General clinical, neurologic data, and Glasgow Coma Scale (GCS) were recorded at admission to ICU. ⋯ The areas under the receiver operator characteristic curves showed that the urinary microalbumin/creatinine ratio [0.81 (95% CI, 0.70-0.92)] and the GCS score [0.78 (95% CI, 0.66-0.90)] at admission were significant predictors of unfavorable neurologic outcome at hospital discharge. The threshold value, sensitivity, specificity, and likelihood ratio for the urinary microalbumin/creatinine ratio were 200 mg/g, 51% (95% CI, 39-64), 96% (95% CI, 90-100), and 11.3 (95% CI, 7.9-16.0); and those for the GCS score were 11, 46% (95% CI, 36-61), 96% (95% CI, 90-100), and 10.1 (95% CI, 7.2-14.1), respectively. This study confirmed a high prevalence of microalbuminuria in ICH patients in ICU, and suggested that the urinary microalbumin/creatinine ratio >200 mg/g was comparable to the GCS score <11 at admission to the ICU with regard to its prognostic characteristics after ICH.

Combined therapeutic hypothermia and barbiturate coma reduces interleukin-6 in the cerebrospinal fluid after aneurysmal subarachnoid hemorrhage.
Inflammatory response with cytokine release is reported to correlate with clinical outcome after aneurysmal subarachnoid hemorrhage (SAH). In selected cases, hypothermia and barbiturate coma are applied as means for neuroprotection after severe SAH. Hypothermia and high-dose barbiturate are reported to attenuate the inflammatory response. ⋯ The mean systemic IL-1beta level was significantly lower in group 1 (P<0.001), as well as the leukocyte counts, both, systemic and in the CSF (P<0.001 and P=0.032). The present data show a most pronounced decrease of IL-6 levels in the CSF, beside decrease in systemic IL-1beta levels, systemic leukocyte counts, and CSF leukocyte counts in group 1, which would be expected to reflect an attenuation of inflammatory response. The impact and role of TNF-alpha remains unclear.

Neurogenic pulmonary edema in patients with subarachnoid hemorrhage.
Neurogenic pulmonary edema (NPE), leading to cardiopulmonary dysfunction, is a potentially life-threatening complication in patients with aneurysmal subarachnoid hemorrhage (SAH). We sought to assess the clinical presentation and risk factors for the development of NPE after SAH. The database contained prospectively collected information on 477 patients with SAH. ⋯ In conclusion, patients with NPE have a high mortality rate more likely due to their severity grade of the bleeding. Morbidity and mortality due to cardiopulmonary failure might be reduced by appropriate recognition and treatment. The awareness of and knowledge about occurrence, clinical presentation, and treatment of NPE, are essential for all those potentially confronted with patients with SAH in the acute phase.
