Background:
Obstetrical brachial plexus lesion (OPBL) complicates a very small proportion of births. The aim of this study was to establish incidence of OPBL at Department of Gyneclogy and Obstetrics during a period of nine years, from 01.01.1996 to 31.12.2004, and to analyse intrapartum risk factors for OPBL.
Subjects And Methods:
The analysis was retrospective and is based on medical documentation from Departments of Gynecology and Obstetrics, Neurology, and Rehabilitation, University Clinical Center Tuzla. We analyzed a group of 86 newborns with OPBL born form 01.01.1996. - 31.12.2004. Differences among study and control groups were compared using Hi2 test. Probability value of p<0.01 was considered significant.
Results:
During nine years period incidence of OPBL was 1.86 per 1000 live-born children. Analyzing maternal factors, and the delivery pattern itself, we have found that the highest factors of risk for OPBL are shortened second stage of delivery (<15 minutes) (p<0.01), and vacuum-extractor assisted delivery of newborns (p<0.01). Newborns, who were delivered vaginally, were not diagnosed to have a higher frequency of OPBL compared to newborns who were delivered by Caesarian section.
Conclusion:
Incidence of OPBL at Departmenf of Gynecology and Obstetrics is 1.86/1000 liveborn children. Most important intrapartum risk factor for OPBL are shortened second stage of delivery and vacum-extractor assisted delivery.
