We conducted this study to compare once-daily dosing regimen to the twice-daily dosing regimen for neonates with birth weight of >/=2500 g during the first 7 days of life. METHODS: Fifty full term infants with birth weight of >/=2500 gm admitted to the neonatal intensive care unit of King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia between November 1999 to October 2000 and received gentamicin at a dose of 2.5 mg/kg every 12 hours (control group) were compared with 50 term infants who received gentamicin at dose of 4 mg/kg every 24 hours during the period of November 2000 until October 2002 (protocol group). Trough and peak serum gentamicin levels (SDL) were measured on all infants. RESULTS: Peak SDL was 8.4 +/- 1.8 mg/ml in the protocol group, compared to 6.7 +/- 2 mg/ml in the control group (p=0.001). Ninety-eight percent (n=49) of the protocol group, compared to 86% (n=43) of the control group, had peak SDL in therapeutic range. Fifty-eight percent (n=29) of infants in the protocol group, compared to 24% (n=12) of infants in the control group, had peak SDL in higher therapeutic range of 8-12 mg/ml. Six percent (n=3) of the protocol infants, compared to 26% (n=13) of the control infants, had trough SDL >2 mg/ml. Six infants (12%) in the protocol group, versus 20 infants (40%) of the control group, required a dosing adjustment. CONCLUSION: Gentamicin dose of 4 mg/kg given at 24-hour interval achieved significantly higher peak and safe trough serum concentrations in term infants, compared to the twice-daily regimen of 2.5 mg/kg. We suggest that measurement of gentamicin concentration may be not required when once-daily regimen is prescribed for 72 hours to term infants with suspected sepsis  ISSN : 0379-5284  Journal Name : The Saudi Medical Journal  Volume : 24  Issue Number : 9  Publishing Year : 1424 AH 2003 AD  Article Type : Article  Added Date : Monday, August 31, 2009  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email سعد الصاعدي Al-Saedi, Saad Researcher Doctorate   Files File Name Type Description  29342.zip zip   Back To Researches Page
