Bacteremia among Children in Central Teaching Hospital of Pediatric in Baghdad City

Introduction: children with Occult bacterimia shows presenceof fever, difficulty in breathing, tachycardia, refusal of feeds,malaise or lethargy. In such a potentially life-threateningcondition, isolation of the causative pathogen in blood cultureis one of the most important bacteriological examinations withimportant clinical and therapeutic consequences.Material and methods: This prospective study was carriedout in the Central Teaching of Pediatric Hospital in Baghdad.Total 300 febrile patient aged from 1 days to 11 years of agewithout any localizing clinical features attending centralteaching hospital of pediatrics in Baghdad and who werenot hospitalized 30 days prior to the initial evaluation wereenrolled into the study.Results: Among 300 patients, 49 were positive for differentkinds of bacteria confirming OB and 235 were negative after18 hrs of incubation. Among different age groups, OB waspositive in 9.7% in age group 1day-<29 days, 4.3% in agegroup 1 month -<11 months, 1.0% in age group 1year-<5 yearsand age group 5years-10years represent (3/49) respectivelyand 0.3% in age groups over 11years.Conclusion: Occult bacteremia is the most prevalent conditionamong children’s less than one months. Imipenem, class ofquinolone antibiotic is found to be sensitive towards bacterialisolates and thus could be

Comparison of Two Different Doses of Dexmedetomidine as an Adjuvant to Intrathecal Bupivacaine in Patients Undergoing Femur Surgery.

Background: Duration of action of local anaesthetic is an important limiting factor in spinal anaesthesia. Dexmedetomidine, selective α 2- agonist has been recently used in addition to other adjuvants to prolong the duration of intrathecal local anaesthetics. Aim: To compare two different doses of dexmedetomidine added to heavy bupivacaine 0.5% intrathecally for femur surgeries. Methods: In this prospective double blind trial, one hundred and twenty patients were randomly allocated into two groups, D1 and D2. Group D1 received 12.5 mg 0.5% hyperbaric bupivacaine and 5 μg dexmedetomidine. Group D2 received 12.5 mg 0.5% hyperbaric bupivacaine and 10 μg dexmedetomidine. Results: Sensory and motor block were comparable in both groups in terms of characteristics like the highest level of sensory block achieved, time to achieve maximum sensory block and time of two segment regression, time to achieve maximal motor block and duration of regression to Bromage scale 0. However time of first analgesic request and total analgesic requirement were significantly reduced by increasing intrathecal dose of dexmedetomidine to 10 μg without any undesirable effects. Conclusion: Intrathecal dose of 10 μg dexmedetomidine provided an increased duration of sensory compared to 5μg dosing, with no significant increase in duration of motor blockade or the incidence of hypotension, bradycardia and any other undesirable side-effects.
