Although there are many studies about catheter related infection in industrialized countries, very few have analyzed it in emerging countries. The aim of our study was to determine the incidence, microbiological profile and risk factors for catheter-related bloodstream infection (CRBSI) in a Tunisian medical intensive care unit. Over eight months (1 January(More)
OBJECTIVE We compared extubation time following daily interruption of sedation in intensive care unit patients with renal impairment with two sedation regimes remifentanil-midazolam and fentanyl-midazolam. STUDY DESIGN Prospective, randomized double-blind trial. PATIENTS AND METHODS Patients with renal impairment needing mechanical ventilation for more(More)
BACKGROUND AND OBJECTIVE The aim of this study is to compare the efficiency of low dose vs. varying doses of hyperbaric bupivacaine in spinal anesthesia for endoscopic urological procedures. METHODS Sixty consecutive patients were studied in a randomized prospective manner. They received either of 5 (Gr I), 7.5 (Gr II) or 10 mg (Gr III) of hyperbaric(More)
BACKGROUND Cardiopulmonary bypass induces a nonspecific inflammatory response. Procalcitonin has been advocated as a specific biomarker for infection. The authors studied the accuracy of procalcitonin to diagnose postoperative infection after cardiac surgery and compared it with those of C-reactive protein, white blood cell count, and interleukins 6 and 8.(More)
The aim of this study is to report the emergence of IncA/C conjugative plasmids harboring blaTEM-24, blaDHA-1, qnrA6, and aac(6')-Ib-cr genes among Providencia spp. isolates recovered in 2008 in Tunisia. The double-disk synergy test confirmed the phenotype extended-spectrum β-lactamase (ESBL) in 2 Providencia stuartii and 5 Providencia rettgeri. These ESBLs(More)
BACKGROUND Hypotension is a common complication following spinal anesthesia for cesarean delivery. Techniques to prevent hypotension include preloading intravenous fluid. AIM To compare the effect of two preloading regimens: 6% hydroxyethyl starch (HES) and 9‰ saline solution, to prevent hypotension after spinal anesthesia in cesarean delivery. METHODS(More)
